What Stampli does
Stampli is a procure-to-pay platform built around accounts payable. Its AI handles the repetitive daily work — capturing invoice data, suggesting coding, matching invoices to purchase orders, flagging duplicates, and routing approvals — so your finance team spends less time on manual entry and more time on oversight.
Rather than replacing your ERP, Stampli sits alongside it. Your ERP stays the system of record; Stampli mirrors its structure, including chart of accounts and approval hierarchies, and passes validated data back. This means your accounting data stays where it already lives, and your team doesn't have to learn a parallel system.
Beyond AP, the platform extends into vendor onboarding, payments (check, ACH, virtual card), and employee purchasing. Each module connects to the same workflow, so a purchase request, the resulting invoice, and the final payment all move through one traceable, auditable process.
Key capabilities
AI-driven invoice processing
Stampli AI handles coding, PO matching, duplicate detection, and risk flagging across invoices. The vendor states it handles on average 87% of finance work across more than 2,700 unique fields.
Centralized approval routing
Invoices move through configurable approval workflows with internal and external messaging attached directly to each invoice, keeping all communication in one place.
ERP-aligned integration
Pre-built integrations cover QuickBooks Desktop and Online, NetSuite, SAP ECC and S/4HANA, Sage Intacct, Microsoft Dynamics GP, 365 BC and Finance, Oracle Fusion, and others — all built in-house by Stampli.
Vendor management and compliance
Vendors onboard through a dedicated portal; Stampli reviews payment-detail changes and enforces compliance checks before any invoice or payment moves forward.
Payment execution with controls
The platform supports check, ACH, global ACH, wire, and virtual card payments, with ERP validation and vendor-readiness checks applied before funds are released.
Audit trail on every action
Every step in the workflow is documented in an immutable audit trail, which Stampli says is ready for inspection at any point.
Best for
- Finance teams processing a meaningful volume of invoices manually who want to reduce keying, chasing approvals, and paper handling
- Businesses that already use a supported ERP (QuickBooks, NetSuite, SAP, Sage, Dynamics, Oracle Fusion, Acumatica, Dealertrack) and don't want to replace it
- AP departments that need clear, real-time visibility into where each invoice stands and who is holding it up
- Companies looking to grow invoice volume without proportionally adding AP headcount
- Organizations that need a documented, auditable approval process — for compliance, audit, or internal control reasons
Worth knowing
- Pricing is custom and not published; you will need to go through a sales conversation to get a number, which makes quick budget comparisons harder.
- Implementation is estimated at three to six weeks — reasonable, but not instant. Plan for some internal project coordination, especially around ERP configuration and user onboarding.
- The platform's value is closely tied to its ERP integrations. If your accounting system is not on Stampli's supported list, verify compatibility before engaging.
- Stampli covers the full procure-to-pay cycle, but if your only need is a lightweight expense tool or simple receipt capture, the platform may be broader than you require.
- As with any AP automation tool, the AI's coding suggestions improve as it learns your chart of accounts and patterns — expect some tuning period after go-live rather than perfection from day one.
