Stampli

AI-powered AP automation built around the invoice, not the ERP.

Overview

Stampli sits between the native AP module inside an ERP and a standalone payments platform like BILL, adding AI invoice capture, coding suggestions, PO matching, and approval workflows on top of NetSuite, Sage Intacct, SAP, Microsoft Dynamics, or 70-plus other ERPs without requiring an ERP migration.

Stampli covers three stages of the AP workflow:

**Intake.** A vendor invoice arrives by email, paper scan, or supplier portal. Stampli's AI reads the document, extracts the header data and line items, and creates a record without manual typing. The supplier is identified, the invoice number is checked for duplicates, and a draft entry is queued. AI coding suggestions appear at this stage, drawn from historical patterns on similar invoices for the same vendor.

**Process.** The draft moves into review. Each invoice has its own communication thread attached, so AP staff, approvers, and vendors can ask questions without leaving the platform or losing context in email. Purchase orders match automatically against invoice lines, with mismatches flagged for human review. Approval routing follows custom rules and logs every decision for the audit trail.

**Handoff.** Approved invoices post to the connected ERP. API connections cover Oracle NetSuite, Sage Intacct, Sage 100, QuickBooks Online, QuickBooks Desktop, SAP ECC, SAP S/4HANA, Microsoft Dynamics GP, Microsoft Dynamics 365, and Acumatica. File-based transfer extends to Workday, Infor, Epicor, Yardi, Blackbaud, and others. NetSuite gets a Built for NetSuite verified connection; Sage Intacct gets Sage Recommended Solution status.

Optional add-on modules cover procurement, direct payments through Stampli Direct Pay, a Stampli Credit Card, and vendor management. Every plan includes unlimited entities, unlimited vendors, twelve pre-built dashboards, a dedicated customer success manager, and a sub-90-second support response time.

Stampli does not publish pricing publicly. Quotes are based on invoice volume and business requirements, and no free trial is offered. An accountant and reseller partner programme is available with revenue sharing and co-marketing support.

Pros and Cons

Pros

  • Mid-sized firms whose clients run NetSuite, Sage Intacct, or SAP and want AP automation without an ERP migration.
  • Practices that need strong purchase-order matching and AI coding suggestions on every invoice line.
  • Multi-entity clients with high invoice volumes that justify a custom-priced enterprise AP platform.

Cons

  • Firms that want published pricing or a free trial. Stampli quotes by volume and offers no trial.
  • Solo bookkeepers with fewer than a few hundred invoices a month. Stampli is built for higher volumes.
  • Clients on QuickBooks Online only with no need for PO matching. Cheaper AP tools handle that workflow.

Pricing

No public pricing. Stampli quotes directly.

Frequently asked questions

What is different about Stampli compared to other AP automation tools?
Stampli's defining feature is keeping all bill discussion, approval activity, supplier communication, and audit trail on the bill itself rather than spread across a separate workflow tool, email, and Slack. When a manager picks up a flagged bill, the entire conversation history (who asked what, who approved, who pushed back) is right there. Other AP tools force you to switch between the bill, the workflow engine, and the chat tool to reconstruct the history. The pattern fits clients with complex approval workflows or where audit trail clarity matters.
How much does Stampli cost?
Stampli prices on application based on bill volume, user count, and integration scope. Public pricing is not transparent. Year-one spend for a mid-market client with moderate bill volume typically lands between 8,000 and 25,000 USD across software, onboarding, and integration setup. The pricing model favours mid-market businesses over very small ones; for clients with under 100 bills per month, BILL or Melio are usually more cost-effective.
What approval workflows does Stampli support?
Single approver, multi-step approval, threshold-based (different approvers for bills over a set amount), department-based, project-based, vendor-based, and conditional combinations. The approval engine is one of Stampli's strengths and handles the kind of governance rules that mid-market businesses actually have rather than the simplified flows assumed by smaller AP tools. Test the approval flow with your client's real rules during evaluation, since some niche combinations may need workarounds.
What AI features does Stampli have?
AI bill capture from email or supplier portals, AI auto-coding against the client's chart of accounts and supplier history, AI-assisted supplier matching (catching duplicate suppliers), and AI-flagged anomalies on unusual amounts or new suppliers. Stampli's AI is among the more accurate in the AP space because it learns from the conversation history on each bill in addition to the structured fields, which gives it more context than competitors that only train on field-level data.
Does Stampli work outside the US?
Stampli is US-focused. The platform handles US domestic ACH, US wire, US check, and international wire on outbound payments. UK, Australian, EU, and other domestic payment rails are not supported. UK and Australian firms with a similar approval-flow-heavy use case typically use Tipalti, which has stronger international payments support but less depth on the conversation-on-the-bill model.
