Quick Answer
Choose the model that covers fixed and variable costs at realistic cohort volumes and gives buyers an understandable invoice. Flat plans can lose money when usage rises; transaction and hybrid plans need reliable metering. Test the economics and safe cutover before choosing.
How to Choose Between Per-Transaction and Subscription Pricing#
For a payment platform, the right pricing model is the one your unit economics and billing operations can actually support, not the one that looks cleanest on a pricing page. In practice, teams usually choose among three mechanics: usage-based billing, per-transaction pricing, and recurring subscriptions, or combine usage-based and recurring charges where supported. Each one changes revenue behavior, invoice logic, and margin risk.
Per-transaction pricing charges for defined billable payment events. A flat subscription charges a recurring amount for an agreed scope; usage can still be billed within a subscription. A hybrid combines a base fee with usage charges. Define the commercial unit separately from the billing relationship.
Operational readiness is the other gate. A usage-tied model depends on clean metering, reliable usage ingestion, and threshold monitoring before invoicing. The usage-based billing lifecycle published by Stripe explicitly includes ingestion as a core component. If event records are late, duplicated, or hard to reconcile, invoice disputes become more likely.
At-a-glance comparison of per-transaction, subscription, and hybrid#
For most payment platforms, the common tradeoff is straightforward: per-transaction pricing tracks activity, subscription pricing can improve forecastability, and a hybrid combines recurring and usage components when customer behavior is mixed. The right choice is the one you can meter, reconcile, and defend on the invoice.
| Model | Best fit | Revenue predictability | Margin sensitivity to Transaction Volume | Sales simplicity | Onboarding friction for B2B SaaS buyers | Upside | Downside | Common failure mode |
|---|---|---|---|---|---|---|---|---|
| Per-Transaction Pricing | Customers with variable payment activity or low commitment appetite | Lower than fixed recurring plans because charges move with usage | Directly tied to transaction volume because fees are charged per successful transaction | Can be high when framed as pay-as-you-go | Can be lower at entry because there is no recurring commitment | Price tracks activity closely | Harder for buyers that need budget certainty | Billable events can be miscounted, creating disputes |
| Subscription Pricing | Buyers that want a fixed amount at a fixed frequency | Higher because amount and billing cadence are set by plan | Can increase when usage spikes but fees stay flat | Can be high once packaging is clear | Can be smoother for buyers with fixed budgeting; harder for low-commit buyers | Cleaner recurring revenue and forecasting | Can drift from actual platform load and delivered value | Heavy-use accounts on flat plans can erode margin |
| Hybrid Pricing Model | Mixed customer maturity and mixed usage patterns | Medium to high, depending on recurring base vs variable component | Can sit between pure subscription and pure per-transaction, depending on the mix | Moderate because two components must be explained | Moderate because buyers must understand base fee plus usage | Baseline recurring revenue plus usage-linked expansion | More invoice complexity | Customers may understand one component but not the other, leading to pushback |
What matters most in practice#
The main difference is where volatility lands. Per-transaction pricing often makes revenue more variable, while fixed subscriptions shift risk to how well flat fees match actual usage.
A flat fee shifts volume risk to the platform when costs rise with activity. Transaction charges move some of that risk into the customer’s invoice. Compare both at the same volumes and with the same fee, refund and support assumptions.
Buyers choosing between variable and committed spend need sample invoices at ordinary and spike volumes, not processor price examples from another region. Explain minimum commitments, included usage, overages and cancellation terms.
Where Stripe-style usage logic helps and hurts#
Metered billing works best when value is consumption-driven and usage is auditable. It requires recording usage throughout the billing period, and metered invoices are calculated from end-of-period usage multiplied by the unit amount.
It starts to fail when metering quality is weak. Before launch, validate one full billing cycle by reconciling billable-event records and invoice quantities so data errors do not turn into invoice disputes.
Where PayPal-style recurring logic helps and hurts#
Fixed recurring charges can help budget owners plan when service scope is stable. Quantity-based and usage-based components can coexist with a recurring relationship; they need separate units and calculation rules.
The risk is usually commercial fit, not the recurring mechanics themselves. Uneven transaction activity can make flat recurring fees feel expensive in low-activity periods and underpriced in high-activity periods.
Test a hybrid alongside flat and transaction plans when cohorts have different usage patterns. It is useful only when the added metering and invoice complexity earns its keep.

Pick the billing metric before you pick the pricing model#
Choose the meter first. If you cannot explain, capture, and reconcile the unit being billed, both per-transaction pricing and subscription pricing become hard to operationalize and audit.
The core decision is what the customer is paying for: Transaction Volume, Payment Value Processed, Payment Method, or API Call. Packaging and metric are separate decisions, and subscription plans can still use quantity-based tiers.
| Billing metric | What you are charging for | Usually works when | Verification detail | Common failure mode |
|---|---|---|---|---|
| Transaction Volume | Number of processed transactions | Transaction count is a measurable usage unit for your product | Reconcile billable counts against recorded usage for the full billing period | Reconciliation gaps |
| Payment Value Processed | Value moved through the platform (if your definition is explicit) | Customers and internal teams use the same definition of processed value | Verify that value definitions, period extracts, and invoice math are consistent end to end | Value definitions are inconsistent across teams or systems |
| Payment Method | Different charges by method used | Your economics vary by payment method | Confirm payment-method mapping on each invoice line | Method-mapping gaps |
| API Call | Requests sent to your APIs (and related data transfer) | Product value is tied to programmatic usage | Validate usage-event capture throughout each billing period before billing | Recently received events are not yet reflected in summaries or upcoming invoices |
The metric quality test#
A billing metric is only strong if it passes three checks: customers understand it, it reflects value, and your team can audit it.
| Check | What to confirm | If it fails |
|---|---|---|
| Customer understanding | Customers understand the meter | Acceptance gets harder even when calculations are technically correct |
| Value alignment | The metric reflects how customers get value | The price feels arbitrary |
| Auditability | Usage is recorded throughout each billing period and usage records still reconcile to invoice quantities despite processing lag | Usage records and invoice quantities do not reconcile |
Customer understanding is a gate, not a nice-to-have. If customers do not understand the meter, acceptance gets harder even when calculations are technically correct. Value alignment matters just as much. If the metric does not reflect how customers get value, the price will feel arbitrary.
Define a billable event precisely: for example, one completed payment, excluding failed attempts and transport retries. State whether refunds reverse the platform fee, which timestamp and timezone choose the billing period, how late events are corrected, and which currency and FX rule apply. Preserve business event ID, customer, unit, amount, price version and effective time so an invoice can be reconstructed.

Where unit economics actually flip the decision#
The decision often flips when variable payment costs rise faster than revenue per customer. If your cost to serve moves with each payment, each dollar processed, or payment method mix, per-transaction pricing can protect margin. If your cost base is mostly fixed and demand is stable, subscription pricing can be easier to defend.
For a per-transaction price p and variable cost v, contribution is (p − v) × transactions minus fixed cost. Fixed cost ÷ (p − v) gives the transaction count needed to cover fixed cost only when p exceeds v. For a flat plan, contribution is monthly fee minus fixed cost minus variable cost × transactions: more volume can reduce profit rather than reach the same break-even point.
Fixed cost recovery vs variable cost recovery#
A fixed-pricing subscription plan charges a fixed amount at a fixed cadence. It fits when platform costs are mostly fixed and do not change much per additional payment. In that case, a recurring fee can recover baseline account cost and improve forecastability.
Use your contracted cost stack by payment method and ticket size. A percentage fee responds to processed value; fixed cents respond to event count. Neither is interchangeable with your own platform revenue price.
That is why flat monthly plans can look good in sales but still create finance risk. As usage grows, the customer's effective unit price under a subscription can fall, while processor costs may not. In spike months, that can push margin below plan assumptions.
Break-even view by customer profile#
Compare the same customer under each model. The following invented inputs are for arithmetic, not market rates: fixed account cost $40/month, variable cost $0.06 per completed transaction; transaction price $0.15; flat fee $100; hybrid $50 including 500 transactions plus $0.12 per extra transaction. Taxes, refunds and other costs are excluded here and must be added to your forecast.
| Completed transactions/month | Cost: $40 + $0.06 × volume | Transaction revenue / contribution | Flat revenue / contribution | Hybrid revenue / contribution |
|---|---|---|---|---|
| 200 | $52 | $30 / −$22 | $100 / $48 | $50 / −$2 |
| 1000 | $100 | $150 / $50 | $100 / $0 | $110 / $10 |
| 2000 | $160 | $300 / $140 | $100 / −$60 | $230 / $70 |
At 1000 transactions the hybrid contributes $10 on $110 revenue, a 9.1% margin. At 2000 it contributes $70 on $230, about 30.4%. The flat plan breaks even at 1000 transactions and loses money above that volume with these inputs. The transaction plan needs at least 445 completed transactions to cover its $40 fixed cost.
Gross margin protection when usage spikes#
Model ordinary and spike usage by payment method, refund rate and support workload. A blended average can hide a loss-making cohort even when total revenue rises.
Avoid promising unlimited processing at a flat fee unless the plausible upper volume remains viable. If you choose hybrid, define included units and overage rules explicitly rather than relying on the billing vendor’s plan labels.
Use subscription pricing to recover fixed platform cost and support budgeting when usage is stable enough that effective unit price remains above variable cost. Use per-transaction pricing, or hybrid pricing with explicit overages, when costs move with payments and spikes are a real operating condition.

Best-fit model by platform stage and customer segment#
Choose the model by what you can close and what you can reconcile. Lean on per-transaction pricing when low entry friction drives growth. Lean on subscription pricing when budgeting certainty drives procurement. Consider a hybrid when cohorts are mixed and costs still move with payment activity.
Segment by observed buying needs and cost behavior. An SMB with steady high volume can behave differently from an enterprise customer with low, erratic use; company size alone does not determine the model.
| Platform stage and segment mix | What usually matters most | Recommended pricing bias | What to verify before launch |
|---|---|---|---|
| Early-stage Payment Platform with mixed SMBs | Fast signup, low commitment, easy first value | Per-Transaction Pricing, or hybrid with a light base fee | Verify effective unit price clears variable processing and support cost in both average and spike months |
| Mid-market B2B SaaS expansion | Budget clarity, approval flow, predictable invoicing | Subscription Pricing, often with usage overages | Confirm billing-cycle invoice clarity and reliable usage ingestion before adding overage logic |
| Enterprise-heavy distribution | Custom terms, procurement requirements, volume sensitivity | Hybrid or negotiated subscription with usage components | Validate custom-package governance, exception logging, and KPI monitoring at the account level |
Early-stage with mixed SMBs#
For early customers, pay-as-you-go may reduce commitment at signup. Test whether revenue still covers onboarding and support at low volumes; a base fee or minimum commitment can change that result.
Use this bias when activation speed is the primary constraint. Before rollout, test real transaction patterns by cohort so your planned take rate remains defensible if usage spikes.
Mid-market B2B SaaS expansion#
A recurring fee may suit procurement that needs predictable budgets. Fixed fees can be invoiced in advance while metered usage is billed in arrears; recurrence does not imply all charges arrive at the end of the cycle.
If usage variability can compress margin, keep the subscription anchor and add usage overages. Only add them when your billing operations can ingest usage data and monitor thresholds and KPIs consistently.
Enterprise-heavy distribution#
Enterprise buyers may need negotiated commitments, usage limits and service scope. Version those terms in the plan catalog so a custom deal can be reproduced on the invoice.
A practical pattern is one commercial spine: recurring charges for baseline platform value plus usage-linked charges where payment activity drives cost. Pick the structure your unit economics and Revenue Operations maturity can support at month-end close.
For a step-by-step walkthrough, see Usage-Based Billing for Platforms That Holds Up at Month-End Close.
Hidden costs and failure modes teams underestimate#
The most expensive pricing mistake is often not the model choice on paper. It is choosing a model your buyers cannot follow, your margins cannot absorb, or your billing team cannot defend at month end. If you cannot explain an invoice in one pass to Finance and Customer Success, the design is probably too complex for scale.
Where each model usually breaks#
Per-transaction pricing can lose margin when payment-method costs or refund behavior change. Review costs and the billable-event definition by cohort rather than assuming a stable blended take rate.
Subscription pricing can break when the fee loses a visible link to customer value. Risk increases when Payment Value Processed moves sharply but the price stays flat, because buyers start asking why price is disconnected from the activity they can see.
Hybrid pricing can reduce both risks, but it adds operational burden. A flat fee with overages stays simple only when included limits, overage units, and customer-visible usage are easy to audit.
The operational burden teams skip#
Meter aggregation can lag ingestion. Compare durable product records, the provider’s accepted usage and the finalized invoice for the same cutoff. An acknowledgment of an API request is not proof that the invoice includes it.
| Issue | Article detail | Risk |
|---|---|---|
| Asynchronous meter processing | Meter events are processed asynchronously, so upcoming invoices and summaries might not immediately reflect recently received events | Metering and invoices fall out of sync |
| Limited meter edits | After a meter is configured, only the display name can be changed | Wrong event or aggregation logic can force migration, credits, and customer explanations |
| Pre-aggregated overwrite behavior | A newer event in the same hourly or daily window can overwrite the previous one | Billing mismatches, including potential underbilling |
Persist each accepted business event and the local metering effect atomically, protected by a unique identifier. Keep the correction history. Provider API idempotency protects a documented scope and retention window; it does not replace durable local deduplication. Query an unknown submission before creating a replacement event.
For a pre-aggregated meter, distinguish a replacement total for the same window from an incremental event. Follow the deployed provider’s rules for ordering, accepted timestamps and corrections; replay must not silently add a window total twice.
Before launch, run shadow billing on real cohorts and compare three numbers for the same period: product-side usage, billing meter totals, and invoice line items. If they do not align within your tolerance, delay overages.
Warning signs worth treating as pricing problems#
Some signals show up early. Treat these as pricing signals, not just support noise:
- dispute activity rising
- repeated customer questions about overage calculations
- discount requests that remove usage charges without changing service scope
- growing manual credits at month end
- accounts where Payment Value Processed and perceived value are consistently misaligned
Review base fee, included usage and overage economics together when approving discounts. Any changed customer terms need the agreed notice, consent and effective-date process; a margin problem does not permit unilateral mid-cycle repricing.
Finance controls that keep pricing honest after launch#
After launch, treat pricing as a finance control system, not a product experiment. In practice, that means recurring checks on margin, plan-level retention signals, and forecast-versus-actual transaction volume, with documented evidence for pricing changes that affect billing or reporting controls.
Payment revenue is volume-sensitive, and profitability can shift as subscription and transaction-fee mix changes. A recurring review should test whether actual Transaction Volume, plan mix, and gross margin match what the forecast assumed, not just whether booked revenue landed on target.
The control points that matter most#
A practical monthly review includes three checks:
Review gross margin by plan family, not only in aggregate, because shifts between subscription and transaction-fee revenue can change profitability.
Track churn separately for subscription billing, usage-based pricing, and fixed fee plus overage plans. Focus on deterioration after packaging changes, discounts, or overage-term changes, not on a universal churn threshold.
Compare forecasted and actual processed volume each period. Misses here can quickly distort both revenue and margin in payment businesses.
Review forecast variances by cohort and explain volume, fee mix, refunds and exceptions separately. Recurring revenue improves predictability only if renewals and the underlying cost assumptions hold.
What Finance should ask from each model#
| Model | Finance upside | What to monitor closely | Common red flag |
|---|---|---|---|
| Subscription billing | More predictable recurring billing at regular intervals | Cohort churn, discounting, and value-to-price alignment | Fee stays flat while customer activity changes materially |
| Usage-based pricing | Better expansion capture as consumption grows | Volume variance, meter-to-invoice alignment, and margin sensitivity | Growth with weak forecast confidence or rising month-end adjustments |
| Fixed fee and overage | Baseline predictability plus upside from higher usage | Included limits, overage incidence, and invoice explainability | Repeated overage disputes or exceptions |
The evidence pack that keeps decisions auditable#
Keep consistent documentation for each pricing decision, such as change logs, approval records, and reproducible Revenue Operations extracts. For SEC registrants, changes that affect internal control over financial reporting must be evaluated during the quarter, so pricing changes that affect billing or reporting controls should follow that path.
Before sign-off, verify data accuracy and completeness across source usage, billing extracts, and posted invoice totals for the period. If those do not align, resolve the data issue before repricing.
A governance cadence that prevents reactive repricing#
Set a governance rhythm that fits your operating model and use it consistently. Run recurring operating reviews for margin, churn, and variance, and define off-cycle repricing triggers in advance, such as persistent variance, plan-specific churn deterioration, or repeated exceptions.
That keeps you from rewriting plans because of one noisy period and helps separate a real pricing issue from a control break.
Product and billing architecture requirements#
Keep meter records, invoice calculation, payment collection and revenue recognition separate. Cash can arrive in a batched net payout that includes fees, refunds and earlier periods; it does not establish how much revenue is earned for the invoice period.
| Architecture requirement | Why it matters by model | What to verify | Common failure mode |
|---|---|---|---|
| Billing meters for usage events | Usage and transaction plans depend on correct aggregation across the billing period. Hybrid plans can also rely on this for overages or feature usage. | Confirm meter definitions match the commercial promise, and raw meter events roll up to the same billable count Finance expects. | Billing uses a metric customers cannot audit, or unlike events are merged into one billable unit. |
| Invoice line-item clarity | Subscription logic needs the base fee to be explicit. Usage and transaction logic need variable charges broken out clearly. | Generate sample invoices and verify each billed component appears as its own invoice line item with clear explanation. | Customers see a total but cannot tell what came from volume, payment-method mix, or fixed fees. |
| Idempotent billing event handling | Retry-heavy pipelines can create duplicate billing side effects without idempotency controls. | Durable local business-event/effect deduplication; scoped provider keys; query unknown outcomes before replacement. | Duplicate billing after retries, followed by credits and manual cleanup. |
| Settlement and payout visibility | Unit economics depend on transaction-level costs, payout timing, and Merchant of Record (MoR) context. | Bridge gross payments, fees, refunds and disputes through payout batches to bank receipts; recognition follows the revenue policy. | Billing appears healthy, but settlement reveals margin gaps from payment-method cost differences or payout timing. |
Architecture should stay tied to pricing logic. Virtual accounts can improve lifecycle visibility for payment status, merchant payouts, and withdrawals, which matters when payment flows affect pricing or reconciliation. MoR status should also be explicit in your data model, because the party shown as receiving payment affects charge explanation and transaction responsibility.
Test with late usage, duplicate deliveries, refunds and delayed bank payouts. Bridge invoices to payment allocations and provider balance activity, then to the bank statement; do not force a one-to-one invoice-to-payout mapping.
How to migrate plans without breaking trust#
Use a two-track migration approach when it fits your stack. One documented sequence is to route new signups to the target plan first, then move existing customers in cohorts only after shadow billing and reconciliation show the new logic on real accounts. This can reduce missed legacy accounts and cutover surprises.
Order of operations#
| Step | Action | Control point |
|---|---|---|
| Lock the target design | Finalize plan catalog, meters, invoice line items, and the old-to-new plan map | The target setup and plan map are finalized before migration |
| Route new signups first | Start new signups on the target setup before legacy migration | Avoid creating new legacy subscriptions that get missed |
| Set mapping rules by cohort | Keep the base fee as its own line item for subscription-to-hybrid changes, and group per-transaction customers by recent volume or payment value processed for tier mapping | Each cohort has explicit migration rules |
| Apply supported payment-conditioned changes | Stripe pending updates apply only to supported automatic-collection methods and attributes | Preserve old terms until the required payment succeeds; handle expiry and meter loss explicitly. |
| Map Stripe price changes to the existing subscription item | Use the existing subscription item when running Stripe price changes | Wrong item mapping can leave both old and new prices active on one subscription |
| Cut over in waves | Start with low-complexity accounts, then expand | Expand after lower-complexity accounts |
Stripe pending updates have method and attribute limits; do not assume they protect every migration. On expiry, outstanding metered usage can be discarded, and removing a metered price can lose intervening usage outside documented flexible-billing behavior. Preserve the final old-plan usage snapshot, test expiry and failure, and reconcile the resulting invoice before replacing a metered component.
Transition mechanics customers actually feel#
Use a grandfather clause where economics support it: existing customers keep their original price while new customers get the new one. Define each cohort rule explicitly: who stays on legacy pricing, what event ends it, and which renewal or contract event triggers the move.
Send notices using each contract’s change and renewal requirements. Include the effective cycle, new rates, included units, overage math and customer choices before the change takes effect.
No-surprises cutover and rollback rules#
Run shadow billing before cutover. Stripe invoice preview lets you view upcoming charges without creating a real invoice, and Zuora supports pre-activation preview with simulated usage charges and tax calculation. Then require Revenue Operations to reconcile previewed charges against historical activity, settlement detail, and customer-facing invoice logic.
Keep a cohort evidence pack with customer list, old and new mappings, sample previews, expected deltas, notice status and rollback owner. Announce dates only after your actual data and integration are ready.
Define rollback before launch. Pause or roll back if:
- churn, cancellation intent, or support contacts exceed pre-approved tolerance for that cohort
- invoice preview outcomes and Revenue Operations reconciliation do not match on real accounts
- dispute or fraud levels move outside acceptable range for your setup
Watch customer disputes and support contacts during migration against pre-approved internal triggers. If they rise, pause expansion, investigate and keep charging only under valid agreed terms.
Decision checklist for the next pricing cycle#
Make the next pricing decision only when you can defend it with billing evidence, not preference. If your team cannot audit meters, explain invoice lines, or reassess variable consideration at each reporting date, keep the simpler model for one more cycle instead of forcing a hybrid.
Confirm model fit#
Start with unit economics and segment behavior, not plan labels. A subscription plan sets a predefined billing amount and cadence. Usage-based billing charges based on customer consumption. Choose the model that fits your economics and the value signal you can measure reliably.
Pressure-test the billable metric before you price on it. Confirm the metric is understandable to customers, aligned to value, and auditable in your records. If the metric is noisy, delayed, or frequently challenged, do not make it your core commercial promise yet.
Verify operational readiness#
For usage pricing, confirm clear ownership across the four lifecycle components: ingestion, catalog setup, billing, and monitoring. Also confirm the meter is in place before promising alert-based controls, including threshold alerts and threshold-triggered invoicing.
Treat billing transparency as a launch requirement. Group invoice line items so customers can interpret charges, keep invoice identifiers consistent for tracking and reconciliation, and check invoices for accuracy, tax, and legal compliance. If you rely on advanced usage billing, do not assume reporting is complete by default. Verify Revenue Operations can actually report and reconcile the model you plan to ship.
Validate complexity budget and lock the call#
Hybrid pricing can work, but complexity rises quickly when you manage many rates across one or more meters. If support cannot explain variable line items clearly, or reconciliation repeatedly needs manual investigation, your complexity budget may already be stretched.
| Decision | Choose it when | Must be true before launch |
|---|---|---|
| Keep current model | Economics and segment behavior still match | Recent invoices reconcile cleanly |
| Switch | Current metric or plan shape is misaligned | New meter, invoice logic, and Revenue Operations reporting are verified |
| Hybridize | You need both budget certainty and usage capture | Base fee and variable metric are separately auditable and customer-explainable |
Make the decision explicit: keep, switch, or hybridize. Assign one owner, set the effective cycle, and require a finance review checkpoint at each reporting date when variable consideration is involved.

Frequently Asked Questions
Which is better for payment platforms, per-transaction or subscription pricing?
Neither is universally better. Per-transaction pricing is a stronger fit when value rises with consumption and your usage metric is easy to explain and audit. Subscription pricing is a stronger fit when customers want budget certainty and you can deliver ongoing value, which supports more predictable recurring revenue.
When should a payment platform use a hybrid pricing model?
Use a hybrid model when you need a predictable base and still want upside from higher usage. This can be a practical middle ground when customer usage patterns are uneven. Only launch it if the base fee and variable charges are each clear and auditable.
What are the biggest risks of usage-based pricing for B2B SaaS payments?
The biggest risks are revenue volatility, arrears billing complexity, and heavier operational pressure. Usage-based billing requires explicit usage recording and reporting, often through meter events tied to charges. In practice, operational strain shows up as billing disputes and reconciliation pressure.
How can we keep pricing aligned with customer value without losing forecast predictability?
Start with a usage metric that maps to customer value, then add a recurring base fee if forecast stability is a priority. A hybrid structure can preserve usage alignment while improving predictability. Set usage-threshold alerts to help reduce bill shock and protect customer trust.
Which pricing metrics are most defensible for finance and customer trust?
The most defensible metrics are easy for customers to understand, clearly tied to value, and reconstructible from billing records. For payment platforms, a usage metric can work when every charge maps to recorded usage. If a metric is frequently disputed or hard to reconstruct, it is not a strong billing metric yet.
How do we migrate existing customers from subscription to usage-based without churn spikes?
Use phased cohorts and agreed notice. Set one effective cutover with no overlapping billable plans: preserve final old-plan usage, credits, prepaid amounts and entitlements, then verify the new plan. Update the existing subscription item where supported. If replacement is required, prevent both from charging for the same period. A failed cutover must preserve service and unbilled usage without recreating already-posted charges.
