BILL vs Stampli: a published price against invoice approval depth

BILL's own alternatives material names the point at which it stops being the obvious choice: seat costs climbing, payment fees adding up, or a need for 3-way matching, multi-entity AP or many international suppliers. It names Stampli and Tipalti as the tools built for that. So the comparison is less about which product is better and more about where your AP operation sits on that curve.

The seat arithmetic is the thing to do first. On BILL Essentials at $49 and Team at $65, an approver costs the same as an AP clerk; discounted approver-only users start on Corporate at $89. Stampli has no published price but its AP package includes unlimited entities, locations and vendors, so growth in entities does not move the number the way growth in approvers moves BILL's.

BILL is AP and AR automation software: AP, AR invoicing and Spend & Expense cards, with purchase requests, POs and 2-way matching on the $89 Corporate plan. Stampli is AP automation software: invoice capture, AI coding to ERP fields, PO matching and approval routing, with every question kept on the invoice itself. That overlap is real, which is why the two end up on the same shortlist, but the design assumptions underneath differ.

Keep BILL on the list if this is you: small businesses paying mostly US vendors from QuickBooks or Xero. Drop it if this is closer: high invoice volumes across entities, or a large international supplier base. The limitation worth naming up front is that seat cost climbs with every approver, Essentials only moves CSV files, and it is less suited to multi-entity groups with 3-way matching.

Keep Stampli on the list if this is you: mid-sized AP teams whose problem is approvals and coding rather than payouts. Drop it if this is closer: a team whose spend is mostly international, or one that needs a price before the first call. Its own limitation is that no published price and no trial, and the features that round it into a spend platform sit in the higher package.

Matching is the other dividing line. BILL adds purchase requests, POs and 2-way matching on the $89 Corporate plan. Stampli includes semi-automated 2- and 3-way matching, with full automation by its Cognitive AI listed as available on top. If 3-way matching is a requirement, that is where BILL's own material says it is less suited.

The table below carries the facts you can check without a sales call: pricing model, deployment, platform support and trial access. Read it before the demos, then use the sections underneath for the parts that depend on your own environment.

The pricing row is populated on one side only: BILL publishes three per-user plans and Stampli publishes nothing. Read it with the fee and package notes below, because neither figure is the whole cost.

BILL publishes its prices and Stampli does not, which changes how you build the business case for each. Every figure below comes from the vendor's own pricing page, read on 25 September 2026. Nothing here is an estimate, a market benchmark or a range from a third party.

BILL publishes per-user prices: Essentials $49, Team $65 and Corporate $89 per user per month, with Enterprise quoted. Spend & Expense carries no subscription fee. Payment fees sit on top, including $0.59 per ACH payment, $1.99 per mailed check and $19.99 per international USD wire. Trial: A free trial is available in most cases, per BILL's pricing FAQ.

Stampli publishes no prices. Its pricing page lists two packages, Stampli for Accounts Payable and Stampli Beyond Accounts Payable, behind a quote request. Trial: No free trial is listed on the pricing page.

BILL's published cost has three layers and all three are on its pricing page. Subscription: Essentials $49, Team $65, Corporate $89 per user per month, Enterprise quoted, Spend & Expense free. Payment fees: $0.59 per ACH, $1.99 per mailed check, $19.99 per international USD wire. And the plan gates: CSV only on Essentials, two-way QuickBooks and Xero sync from Team.

Stampli's cost is one layer you cannot see. Two packages, quoted, with procurement, Direct Pay, the Stampli Credit Card and advanced vendor management in the Beyond Accounts Payable package. The way to compare is to build BILL's number exactly from its published rates, then ask Stampli to beat it with everything you need included. The AP automation savings calculator will give you the baseline to argue from.

What moves the BILL number: every approver is a paid seat on Essentials and Team, discounted approver-only users start on Corporate, two-way sync with QuickBooks and Xero starts on Team at $65, and payment fees are charged per transaction. For Stampli: semi-automated 2- and 3-way matching is included but full matching automation by its Cognitive AI is listed on top, and procurement, Stampli Direct Pay, the Stampli Credit Card and advanced vendor management come with Stampli Beyond Accounts Payable rather than the AP package. Ask both vendors to put the first-year total in writing, license plus services plus any module you would need in year two, and model it yourself with the AP automation savings calculator before the renewal conversation rather than after it.

Rollout on BILL: self-serve setup with no implementation project. On Stampli: the AP package includes unlimited entities, locations and vendors, so entity count is not the thing that breaks the scope. That is the difference that shows up in the project plan rather than in the demo.

BILL is self-serve with no implementation project and a free trial in most cases, which is a real advantage for a small team with no project capacity. Stampli is an implementation, and the thing to test hardest is the ERP connector: it lists pre-built integrations with more than 70 ERPs including on-premises systems, which is the claim that matters if your ERP is not cloud-only.

Day-to-day, the products serve different people. BILL serves the AP clerk and the accounting system. Stampli serves the approver, keeping every question and answer on the invoice record rather than in email. If you want to know which one that favours, count how much of your AP team's week is spent chasing approvals. For the international version of this question, see the Tipalti and Stampli comparison.

Plan the first close or first cycle after go-live before you sign. Write down who owns configuration changes, who answers an auditor's question about the records, and what happens to your data if you leave. Starting from an invoice approval matrix makes those answers concrete instead of aspirational.

BILL wins when you are a small business on QuickBooks or Xero, you want a price you can budget from today, and a free trial to test it. Stampli wins when invoices stall in approval across several entities and ERPs, some of them on-premises, and approver count would make per-seat pricing painful. If both halves of that sound like you, the tie-breaker is which of the two limitations below you could live with for three years, because that is how long the contract will feel.

Do the seat maths honestly, including every approver, before you accept that BILL is the cheaper option. Twenty approvers on Team at $65 is a different conversation from four, and that is the exact point where BILL's own material says its buyers start looking at Stampli.

The expensive mistake here is rarely picking the weaker product. It is picking the one whose assumptions about your team turn out to be wrong. For BILL the risk is this: seat cost climbs with every approver, Essentials only moves CSV files, and it is less suited to multi-entity groups with 3-way matching. For Stampli: no published price and no trial, and the features that round it into a spend platform sit in the higher package. Both are survivable if you knew about them before signature and planned around them, and both are expensive to discover in month four.
