Stampli Review (2026): Pricing, Features & Honest Verdict

TLDR

Stampli is an accounts payable automation platform built around invoice processing, with Stampli AI doing most of the coding, matching, and approval routing on top of your existing ERP. We found it faster to implement and easier to use than Tipalti or BILL. Best for: high-volume mid-market finance teams. Price: custom, reports from roughly $45/mo. Rating: 7.9/10.

What is Stampli?

Stampli is a procure-to-pay platform that started life as an AP automation tool, and invoice processing is still where it shines. You forward or scan invoices in, and Stampli AI captures the data, codes it to the right GL accounts, matches it against purchase orders, and routes it for approval. Every invoice carries its own communication thread, so the back-and-forth about a charge lives on the invoice instead of buried in email. Over time the product has added procurement, vendor management, payments, and a corporate card, but the core pitch is the same: take the grunt work out of paying invoices.

The AI is the headline. Originally nicknamed Billy the Bot and now branded Stampli AI, the company says it performs on average 87% of finance work across more than 2,700 unique fields. Crucially, Stampli sits on top of your ERP rather than replacing it. NetSuite, Sage Intacct, QuickBooks, and the rest stay the system of record, and Stampli syncs to them. That design is a big reason finance teams adopt it without a painful rip-and-replace project. On G2 it holds a 4.6 rating across more than 1,200 reviews, with support and usability cited as the standout strengths.

What Are Stampli’s Key Features?

Stampli AI for invoice capture and coding

This is the engine. Stampli AI reads incoming invoices, extracts header and line-item data, codes them to GL accounts, and matches them to POs and receipts. The company puts the automation rate at roughly 87% across 2,700+ fields, which in practice means an AP clerk reviews and approves rather than keying everything by hand. It learns your patterns over time, so coding accuracy improves the longer you use it. Stampli pitches the AI as something that does the work day to day rather than a chatbot you query, and that framing matches how teams describe using it: invoices arrive already coded and routed, and humans handle the exceptions.

Invoice-centric collaboration

Every invoice gets its own thread. Approvers, AP staff, and vendors can comment, ask questions, and resolve disputes right on the document. This is the feature reviewers single out most, because it kills the email chains that normally slow approvals down. The full history stays attached to the invoice for a clean audit trail.

Payments and the Stampli Card

Stampli pays vendors by check, ACH, wire, and virtual card, and offers the Stampli Card for upfront spend control. It is solid for domestic payables, and the card adds a layer of pre-spend budget enforcement that finance teams use to stop overspending before it happens. It is not, however, built to be a global payments engine the way Tipalti is, so teams paying hundreds of international vendors across many currencies will find the coverage thinner. A few reviewers also flag that ACH payments can be slow to clear, so if speed of disbursement is critical, test it during a pilot.

Procurement and vendor management

Beyond core AP, Stampli layers on configurable approval workflows, purchase orders, and budget management, plus a vendor portal for onboarding, compliance checks, and messaging. This is what makes it a procure-to-pay platform rather than just an invoice tool. The procurement side is competent but not as deep as a dedicated procurement suite, so treat it as a useful extension of AP rather than the main reason to buy.

ERP integrations

Stampli connects to a deep list of accounting systems: Oracle NetSuite, Oracle Fusion, Microsoft Dynamics 365 BC and Finance, SAP ECC and S/4HANA, Sage Intacct, Sage 100, QuickBooks Desktop and Online, and Acumatica. The integration is two-way and keeps the ERP as the source of truth, which is why setup tends to be quicker than competitors that try to own the ledger.

How Much Does Stampli Cost?

Stampli does not publish a price. Pricing is quote-based and depends on invoice volume, the number of users, and which modules you turn on. From user reports, small businesses see figures starting around $45 per month, while mid-market deployments more realistically land in the $500 to $2,000+ per month range. Unlimited users and vendors are included regardless of tier, and billing is month-to-month with no forced annual lock.

Against named competitors, the picture is mixed. BILL publishes its pricing at $45 per user per month for the Essentials plan, plus per-transaction fees, which is more transparent but built for simpler SMB needs. Tipalti, which MakerStack rated 8.2, is also quote-only and aimed at global payments at scale. Ramp takes a different route entirely with a free AP and spend platform funded by card interchange, so its software costs nothing if the card fits your spend.

The honest takeaway: Stampli’s value is strong if invoice volume is your bottleneck, but the lack of a public price means you cannot evaluate it on a spreadsheet without a sales call. When you do get a quote, ask exactly which modules are included, since procurement, payments, and the card can each move the number, and confirm whether your invoice volume sits comfortably inside the tier. Budget for a demo and a custom quote before you can compare it cleanly against the alternatives, and get the BILL and Ramp numbers in hand at the same time so you are negotiating with real comparisons.

Who is Stampli Best For?

Use Stampli if your AP team is drowning in invoices and you want automation they will actually adopt. It fits mid-market companies on NetSuite, Sage Intacct, or QuickBooks that want to keep their ERP and bolt collaborative, AI-driven AP on top. Teams that have struggled through a rough Tipalti or BILL onboarding tend to rate Stampli’s implementation and support highly.

Skip Stampli if your primary need is paying a large number of international vendors across many currencies, where Tipalti’s payments engine is stronger. Skip it too if you want a free or fully transparent self-serve price, in which case Ramp or BILL will be easier to evaluate. And if procurement and PO control are your main goal rather than invoice processing, look at a procurement-first tool before committing.

One more practical note for finance leaders weighing this: the strongest case for Stampli is when adoption has been your problem, not features. Plenty of teams buy a capable AP tool and then watch approvers ignore it and revert to email. Stampli’s invoice-centric threads and clean interface are specifically designed to keep approvers in the system, and that behavioral win is often worth more than a longer feature checklist. If your last AP rollout stalled because nobody actually used it, that is the signal to put Stampli on the shortlist.

Best Stampli Alternatives

Tipalti

Tipalti is the global payments specialist and the strongest alternative for companies paying vendors across many countries and currencies, with built-in tax compliance. MakerStack rated it 8.2. It is also quote-only, and its onboarding is heavier than Stampli’s, with reviewers citing a two to three month implementation. Choose Tipalti for international payment breadth, Stampli for invoice-processing usability.

BILL

BILL, formerly Bill.com, is the popular SMB pick and publishes its pricing at $45 per user per month for Essentials, plus per-transaction fees like $0.59 per ACH payment. It is quick to set up but lighter on procurement and reporting, which growing companies can outgrow. Pick BILL for simple, transparent SMB AP, Stampli for higher volume and collaboration.

Ramp

Ramp bundles AP automation with corporate cards and spend management, and the software is free because Ramp earns interchange on card spend. That makes it the cheapest entry point by far. The trade-off is that you are buying into Ramp’s card and spend ecosystem, and its standalone invoice features are less specialized than Stampli’s. Choose Ramp if free pricing and spend control matter most.

Final Verdict: Is Stampli Worth It?

Stampli earns its 7.9. It is the AP automation tool finance teams tend to actually like, with AI that handles the bulk of coding and matching, an invoice-centric collaboration model that clears approval bottlenecks, and an implementation that is faster and less painful than its bigger rivals. The 4.6 G2 score across 1,200+ reviews backs that up, and keeping your ERP as the system of record removes the usual adoption fear.

The two honest knocks are quote-only pricing and a payments story that is narrower than Tipalti’s. If you process high invoice volume and want AP your team will adopt without a fight, Stampli is an easy recommendation. Just go in expecting a sales call to get a number, and if global multi-currency payouts are your real problem, test Tipalti alongside it.
