Executive TL;DR
BILL fits teams looking beyond AP to connect customer invoicing, payables, spend, expense, payment options, and accounting sync.
Stampli fits AP teams that want the supplier invoice, its conversation, approval history, payment evidence, and ERP record to stay closely connected.
For the shared AP lane, compare invoice capture, PO matching, approver collaboration, vendor records, payment methods, ERP validation, reconciliation, and audit history.
Finance suite or AP depth
Both pay bills; the surrounding operating model decides the fit
BILL offers a wider business-finance footprint that includes AR, spend, and expense. Stampli builds a focused AP process around the invoice and the ERP that remains the system of record.
BILL connects both sides of business finance
Vendor bills, customer invoices, approvals, payments, spend, expense, and accounting sync can share one product environment.
Stampli makes the invoice the workspace
Capture, coding, matching, approver discussion, vendor context, payment, audit history, and ERP reconciliation stay attached to the supplier invoice.
Bring a difficult invoice to the demo
Use a PO mismatch, changed approver, vendor update, payment exception, and reconciliation issue to see which record keeps the full AP story usable.

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. | SMB and mid-market finance teams that want AP approvals, AR invoicing, payment execution, and accounting sync in a packaged finance workflow. | AP teams that need invoice-centered collaboration and approval control while keeping the ERP as system of record. |
Money flow & contracting Who invoices, who collects, and how funds travel from source to recipient. | Vendor invoice or customer invoice → approval / send / payment → accounting sync. It is AP/AR-centered, not a MoR collect-hold-disburse loop for external recipient programs. | Supplier invoice → coding / matching → approval discussion → payment execution → ERP reconciliation. Client collection and external payout release are distinct categories. |
Onboarding Who gets onboarded, what documents they submit, and who verifies them. | Vendors, customers, approvers, accounting systems, roles, and payment methods are onboarded. Marketplace, creator, affiliate, or contractor payee onboarding does not map cleanly. | AP users, approvers, vendors, ERP connectors, POs, invoice capture rules, and payment methods are onboarded. Payee onboarding for mass creator or marketplace programs is not the model. |
Integrations APIs, webhooks, imports, exports, and the systems each product needs around it. | Accounting sync and developer APIs cover AP/AR objects, vendors, customers, bills, payments, and reports. The strongest integration story is accounting-first. | Pre-built ERP and accounting integrations are central to the product. Integration is optimized for AP objects and ERP reconciliation, not client-funded payee-source ingestion. |
Reporting & reconciliation Export packages, ledger records, and audit trails your finance team closes the books with. | Good for AP/AR close against accounting systems. External payout close still needs source-funding records, payee state, hold reasons, method fees, and exception history. | Invoice conversation, approval history, payment evidence, and ERP sync support AP close. Payout-program reconciliation needs different source and recipient artifacts. |
Pricing model Fee structure overview. Vendor terms change often, so confirm pricing during your evaluation. | Published AP/AR plans include Essentials, Team, Corporate, and Enterprise, plus payment-method and other transaction fees. Model user count, payment mix, spend products, and add-ons together. | Confirm packaging against invoice volume, module scope, ERP environment, user count, implementation services, and payment-method fees. |

Frequently Asked Questions
What is the main difference between BILL and Stampli?+
BILL is a broader financial-operations platform spanning AP, AR, spend and expense, payments, and accounting sync. Stampli is more tightly focused on invoice-centered AP automation and ERP-aligned collaboration.
Which product is built around invoice collaboration?+
Stampli explicitly centers capture, coding, matching, discussions, approvals, vendor records, payments, and audit history on the invoice. BILL provides approval routing within its wider AP and AR suite.
Which product includes accounts receivable?+
BILL includes AR customer-invoice workflows in its current scope. Stampli is positioned around procure-to-pay and invoice-to-pay rather than AR.
How should an ERP-heavy team compare them?+
Use the real ERP, invoice and PO objects, approver roles, vendor fields, payment methods, sync direction, error states, and reconciliation rules. The winning process should preserve a clear audit history without creating duplicate finance records.
If you are switching over
- 01Map the records, identifiers, balances, statuses, and exports your current process depends on before choosing a migration path.
- 02Give BILL and Stampli 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.
