Airbase vs Brex: guided procurement or a card-and-travel-led spend stack?
Airbase organizes non-payroll spend around guided procurement, AP automation, expenses, corporate cards, reporting, and Paylocity for Finance. Brex combines corporate cards, expenses, travel, business accounts, bill pay, reimbursements, and accounting automation.
Compare how each product controls company spend
Follow a request from policy and approval through payment and accounting close. The better fit is the workflow your finance team can operate without extra handoffs.
- · Mid-market and larger teams standardizing guided procurement, AP automation, expenses, cards, and spend analytics
- · Finance orgs that want policy checks before spend commits and reconciliation after payment
- · Companies already on Paylocity that want payroll and non-payroll spend closer together
- · Finance teams standardizing employee spend, travel, reimbursements, and AP policy in one suite
- · Companies that want global card programs with local-currency controls and NetSuite/Xero sync
- · AP teams paying vendor invoices through card, ACH, check, wire, and reimbursement workflows together
The right spend suite should match how purchases enter the company
Follow a planned software purchase, an employee trip, and a supplier invoice to see which product model matches the work finance handles most often.
Procurement-led spend favors Airbase context
Airbase can connect a purchase request to policy, budget, vendor, approver, payment method, and accounting record, with headcount and Paylocity context available in the wider finance offering.
Card and travel activity favors Brex context
Brex brings corporate cards, localized spend policies, travel, reimbursements, bill pay, business accounts, and ERP sync into the employee and supplier spend experience.
Global scope needs entity-level detail
For either product, match card availability, expenses, bill-payment methods, subsidiaries, currencies, treasury or account features, and accounting behavior to the entities that will use them.
Card programs
Reading a card program past the rebate
How a rebate number is built
Take $2m of annual card spend against a quoted 1.5% rebate and the answer is $30,000. Assume, because the quote does, that every dollar is rebate eligible and that the tier holds all year. The constant underneath is interchange, the fee an acquirer pays the card issuer on each purchase, which is set per region and per card type. That is why the figure does not travel. European rules cap consumer card interchange at 0.2% on debit and 0.3% on credit, and they exclude commercial cards from both the caps and the obligation on a merchant to accept them. Some of the spend in the model may never reach the card.
One hotel charge, line by line
Say a card is authorized for $412 at a hotel on Sunday and posts on Wednesday at $437. The $25 is a resort fee and a city tax added at checkout. The descriptor on the statement is the booking platform, which matches no name in the supplier list. The traveler attaches the reservation email, showing a room rate and no tax lines. US substantiation rules ask for documentary evidence on lodging at any amount, where other expenses only need it at $75 and above, and the folio is the document that separates the room, the tax, and the bar tab that codes elsewhere. Getting one means asking the traveler weeks later for paper they never collected.

Feature-by-feature comparison
Six practical questions to take into demos and procurement. Use the same workflow and inputs with both vendors, then compare what your team would actually have to operate.
| Capability | | |
|---|---|---|
Best for Team size, program type, and workflow shape where each product fits. | Teams that want to control non-payroll spend before commitment and reconcile it after payment, especially when HCM and finance data need to sit closer together. | Finance teams that want employee spend controls, travel policy, vendor bill payments, and ERP sync in one spend stack. |
Money flow & contracting Who invoices, who collects, and how funds travel from source to recipient. | Purchase request or supplier invoice → policy approval → card, expense, or bill payment → accounting sync. External payout programs run on different operating rails. | Company spend and vendor invoices flow through cards, ACH, checks, wires, reimbursements, and accounting sync. Client-funded payout holds and MoR invoices are outside the model. |
Onboarding Who gets onboarded, what documents they submit, and who verifies them. | Employees, requesters, approvers, vendors, budgets, cards, expense rules, ERP mappings, and procurement policies are onboarded. External recipient onboarding is not the model. | Employees, approvers, entities, vendors, cards, policies, and accounting rules are onboarded. Creator, affiliate, marketplace, or contractor payee onboarding is a separate workflow. |
Integrations APIs, webhooks, imports, exports, and the systems each product needs around it. | Accounting, HRIS, SSO, card, AP, and spend-data integrations. The strongest fit is procurement and non-payroll spend, not payee-source payout ingestion. | Accounting and ERP sync, travel/expense workflows, business accounts, and spend exports. Integration shape is employee-spend and vendor-AP oriented. |
Reporting & reconciliation Export packages, ledger records, and audit trails your finance team closes the books with. | Spend analytics, vendor context, approval history, and accounting close sync. Payout-program reconciliation requires source funding, payee state, and exception traces elsewhere. | Strong for spend analytics, card/expense records, bill-pay status, and accounting sync. External payout reconciliation still needs source funding, payee status, and hold/release proof elsewhere. |
Pricing model Fee structure overview. Vendor terms change often, so confirm pricing during your evaluation. | Quote-based packaging through Airbase / Paylocity. Validate module bundle, user count, entities, card economics, payment fees, ERP connectors, and implementation scope. | Public plans include Essentials, Premium, Enterprise, and Smart Card tiers; payment methods, travel, treasury, local cards, and international usage can add route-specific economics. |

Exception handling
The address on a failed record
Who the exception is addressed to
A feature grid records that a product handles failed records. It does not record who the failure gets addressed to, and there are two designs behind that one line. In the first, the product contacts the counterparty itself, and the queue your team works is only what is still unresolved after a reminder has gone out. In the second, every failure routes back to your team, and each one becomes a message out, a wait, and a re-entry keyed by hand. Which design you are buying is not usually stated on a product page. Ask what the product sends to a payee whose bank details were rejected, and ask what it does when that payee does not reply.
Take this into your procurement call
Five questions that surface the meaningful fit differences between vendors.
- 1Name the business job, starting record, and team that will own the workflow.
- 2Ask Airbase to demonstrate one normal run and one exception using your inputs.
- 3Ask Brex to run the same scenario so the comparison stays fair.
- 4Compare onboarding, handoffs, exception ownership, support, and the final finance export.
- 5Confirm current pricing, coverage, integrations, and contract scope directly with each vendor.

- 02Give Airbase and Brex the same representative workflow, including an incomplete record and a failed or changed transaction.
- 03Assign an owner to every handoff and exception so gaps do not disappear between product demos.
- 04Run a parallel close before retiring the existing process, then compare the operational and finance outputs side by side.
