Stampli vs AvidXchange in 2026: Which AP Platform Fits Your Finance Team?

Updated August 2026: every figure below was checked against the vendor's own page or a first-party source, dated inline.

Search "Stampli vs AvidXchange" and you're already past the browsing stage. You're a CFO, Controller, or AP Manager who has been told to shortlist an accounts payable automation platform, and these two names keep coming up on every review site and analyst list you've read this month. You want a straight answer on features and price. The features answer is knowable. The price answer, for both of these vendors, is not, and pretending otherwise is how buyers end up embarrassed in a budget meeting three months from now.

That's the first honest thing to say about this comparison: neither Stampli nor AvidXchange publishes a price anywhere on its website. Both run a "Request a Quote" form, both size the deal around your invoice volume, entity count, and module selection, and both expect a sales conversation before you see a number. That alone doesn't decide anything. What decides it is shape: Stampli is built to sit on top of the ERP you already run, wherever that ERP is, while AvidXchange is built deep into a handful of industries and a large supplier payment network. This article walks through both axes, plus a 2025 ownership change at AvidXchange that's worth knowing before you sign a multi-year contract, so you can steer the sales conversation instead of the other way around. For the wider field of vendors that do post a number, our best AP automation software roundup is the right place to start.

TL;DR

• Neither Stampli nor AvidXchange publishes a price. Both are quote-only, and the number you get depends on invoice volume, entity count, modules selected, and how much of your payment volume runs through the vendor's payment rail.
• Stampli is ERP-agnostic by design. It sits as a collaboration and approvals layer on top of the accounting system you already run, SAP, NetSuite, Sage, Microsoft Dynamics, QuickBooks, Acumatica, and more, rather than asking you to re-platform.
• AvidXchange is mid-market and vertical. Its deepest native integrations and dedicated product suites serve real estate, community association management (HOA), construction, financial services, and media through its FastPay product, backed by a large supplier payment network.
• AvidXchange changed owners in October 2025. TPG and Corpay took the company private at $10.00 per share, about $2.2 billion, with Corpay holding roughly a 34% stake. Corpay also owns Corpay Complete, a competing AP platform, which is worth raising directly with your sales contact.
• Stampli remains independent, has raised about $148 million through a Series D round in October 2023, and shipped a new product, Deep Finance, on 31 March 2026.
• Pick based on shape, not a feature checklist. If your ERP is fixed and non-negotiable, start with Stampli. If you're in one of AvidXchange's core verticals and want a bundled suite plus network reach, start there.

Stampli vs AvidXchange at a Glance

Neither Vendor Publishes a Price, and What That Means for Your Evaluation

Neither Stampli's pricing page nor AvidXchange's publishes a single number. Both run "Request a Quote" forms, and both size a deal in a sales conversation rather than a self-checkout flow. That puts them in a different category from some of the AP platforms they get compared against on best-of lists: Ramp and BILL Spend & Expense both publish a $0 entry tier, and Tipalti publishes a $99-per-month floor for its Accounts Payable module, even though all three still layer transaction fees, platform fees, or custom quotes on top for anything past the entry offer (our comparison of BILL and Tipalti walks through how two published-price vendors actually stack up, and our roundups of Ramp alternatives and BILL alternatives cover those free-entry-tier paths in more depth). Quote-only pricing is not, by itself, a red flag. Mid-market AP software is routinely sold this way. But it does mean the burden sits on you to control the sales conversation, not the vendor.

Two things drive a quote at each company, and they are not the same two things.

Because neither number is public, the quote you get is only as good as what you make the vendor put in writing. Ask for all of the following before you compare a Stampli number against an AvidXchange number, or against anything else on your shortlist.

Invoice Capture and AI Coding

Both vendors lead with AI-based invoice capture, and both have added a newer AI layer on top of it in the last year, but they're solving slightly different problems. Stampli centers the invoice itself as a shared workspace: the platform extracts data from the incoming document, suggests coding based on your GL history, runs 2-way and 3-way PO matching, and keeps every comment, approval, and edit attached to that one record. AvidXchange centers the transaction: it captures and digitizes incoming invoices with AI, matches them against purchase orders, and routes coded data into whichever ERP or vertical accounting system you've connected, replicating that system's own entry experience where the integration is deep enough to do so.

Stampli's own marketing describes its AI as functioning like "an autonomous operator, not a copilot," claiming it handles the large majority of routine finance work across thousands of tracked invoice fields (Stampli). That's the vendor's framing of its own product, not an independently audited figure, so treat it as a question for your own pilot rather than a settled fact before you sign anything.

Approvals and Collaboration: Stampli's Strongest Ground

This is the section where Stampli built its reputation, and it's still the clearest reason to shortlist the product. Every invoice lives on a single shared record, and approvers comment, tag each other, and see the full context of the invoice on that record instead of forwarding it through email or a separate Slack thread. Stampli offers two ways to route it: predefined workflows, where you build the approval chain with a workflow builder, and dynamic workflows, where machine learning suggests the likely approver based on the invoice's history. Either way, the audit trail, who commented, who coded it, who approved it, and when, stays attached to one record rather than scattered across a mail thread.

AvidXchange's approval layer works differently. Routing is generally rule-based, configured to mirror the approval chain your finance team already runs, and it lives inside the platform's workflow screens tied to whichever ERP is connected. That's a perfectly reasonable way to automate an approval chain that already works. It's a less natural fit for a team whose real problem is that the chain itself is fuzzy, informal, or spread across departments that don't share a system today.

Payments and the Supplier Network: AvidXchange's Strongest Ground

Flip the axis and AvidXchange pulls ahead. Its AvidPay Network has included more than 965,000 businesses over the last five years, by AvidXchange's own account, which puts it among the larger supplier payment networks built specifically for the mid-market AP category (AvidXchange). Payments run on a per-transaction pricing model, and AvidXchange has stated that AvidPay can operate at no cost to the buyer once at least 50% of payment volume routes through the network, which is the clearest example of how the platform's economics are built around adoption rather than a flat software fee.

Stampli supports payments too, through Stampli Direct Pay and the Stampli Card program, covering check, ACH, wire, and virtual cards. But Stampli isn't positioned as a network product the way AvidXchange is; your payments still route through your existing banking relationships, with Stampli handling the initiation, controls, and reconciliation around them.

There's a fraud angle worth naming here as well, since it applies more directly to a payment-heavy platform like AvidXchange than to a collaboration-first one. Checks remain the single most targeted payment method for fraud: 76% of organizations faced attempted or actual payments fraud in 2025, and checks were involved in 58% of it, well ahead of ACH debits at 30% and wires at 25%, according to the 2026 AFP Payments Fraud and Control Survey (AFP). Moving vendor payments off mailed checks and onto a controlled electronic rail, whichever vendor's rail it is, is one of the more concrete risk reductions either platform offers.

Vertical and Industry Fit

Stampli names its target industries broadly: automotive, construction, healthcare, manufacturing, energy, professional services, and transportation and logistics. Nothing about the product changes shape by industry beyond which integrations you connect; it's the same collaboration-and-approvals platform wherever you deploy it, which is consistent with an ERP-agnostic design.

AvidXchange goes narrower and deeper. It publishes a dedicated AvidSuite for real estate, community association management (HOA), construction, financial services, healthcare, hospitality, technology and software, K-12 schools, higher education, nonprofits, government, and professional services, plus a distinct product line, FastPay, built specifically for media companies. That's a materially different go-to-market than Stampli's: rather than one product serving many industries the same way, AvidXchange bundles industry-specific workflows and integrations into each vertical suite.

ERP and Accounting Integrations

Stampli's own positioning is direct about this: "Your ERP stays the system of record. Stampli mirrors its structure and evolves as it does." It names 14 or more supported enterprise systems, including SAP ECC and S/4HANA, Oracle NetSuite and Fusion, Microsoft Dynamics GP, 365 Business Central, and 365 Finance, Sage Intacct, Sage 100, and Sage Intacct Construction, QuickBooks Desktop and Online, Acumatica, and Dealertrack DMS (Stampli).

AvidXchange advertises more than 240 integrations on its own integrations page, spanning general accounting systems and industry-specific platforms (AvidXchange). Its deepest native builds sit in real estate and property accounting: Yardi, MRI, Rent Manager, and MIP Fund Accounting, the last of which is common in nonprofit and government fund accounting. It also connects to NetSuite, QuickBooks Online, Sage Intacct, Sage 100, Microsoft, and Acumatica for more general use cases.

If Sage Intacct or NetSuite is the fixed point in your stack rather than the AP layer sitting on top of it, our guides to Sage Intacct alternatives and NetSuite alternatives cover that decision directly, and our accounting software roundup covers the category underneath both AP tools.

Implementation and Time to Value

Both vendors sell to mid-market finance teams through a sales-assisted, quote-only motion, so neither is a same-day self-serve signup. Where they differ is what actually takes the time. Stampli emphasizes that its integrations are "built in-house, built in advance and built to completion," which frames the connector work as largely pre-built rather than a custom project (Stampli). The heavier lift on a Stampli rollout is usually mapping your real approval hierarchy into the workflow builder, especially if that hierarchy has never been written down formally.

AvidXchange's timeline depends more on which system you're connecting. A standard QuickBooks Online or NetSuite integration is comparable to Stampli's. A deep, industry-specific build, replicating a property manager's entry experience inside Yardi or MRI, is a bigger project, and the payment side of onboarding adds a step Stampli doesn't have: supplier enrollment onto the AvidPay Network, since the network's cost advantages depend on adoption.

Vendor Stability and Ownership

This is the axis a feature table won't show you, and it changed materially for one of these two vendors in the last twelve months.

Stampli remains independently owned. It has raised about $148 million in total funding, with its most recent round a Series D in October 2023, and as of this year it's still shipping new product: Deep Finance, launched 31 March 2026, analyzes the invoice data Stampli already processes for more than 1,800 businesses and turns it into an executive-level view of vendor concentration risk and contract-driven cost increases (Stampli, via PR Newswire).

AvidXchange's ownership changed on 15 October 2025, when TPG closed a deal to take the company private in partnership with Corpay, at $10.00 per share, about $2.2 billion total. Corpay invested roughly $550 million for a stake of about 34%, and AvidXchange shares no longer trade on Nasdaq (Corpay investor newsroom). That's not a red flag by itself, but it is a genuinely relevant fact for a buyer signing a multi-year AP contract: Corpay also owns Corpay Complete, a competing accounts payable automation platform, and it now holds a meaningful stake in a company it competes against. Whether that shapes AvidXchange's product roadmap going forward is a fair question to put directly to your sales contact rather than assume either way.

When Stampli Is the Right Call

Stampli is the stronger starting point when your ERP is fixed and non-negotiable, whether that's SAP, NetSuite, Sage, Microsoft Dynamics, QuickBooks, or Acumatica, and you have no appetite to re-platform just to get better AP automation. It's also the better fit when the actual pain in your finance function is coordination, approvers who don't respond to email, invoices that get lost between departments, coding disputes that take three back-and-forth messages to resolve, rather than payment infrastructure itself. If your company sits in one of Stampli's named industries generically (automotive, construction, healthcare, manufacturing, energy, professional services, transportation and logistics) without needing a vertical-specific product suite, that's another point in its favor. And if a recent change of ownership at your AP vendor would complicate a rollout you're mid-way through, Stampli's independence and steady funding history is worth something on its own.

When AvidXchange Is the Right Call

AvidXchange is the stronger starting point when you're squarely inside one of its core verticals, real estate, HOA and community association management, construction, financial services, or media through FastPay, and you want a bundled product suite built for that industry rather than a generic AP layer. It also makes more sense when you process high invoice and payment volume and can realistically commit meaningful spend to one payment rail, since the AvidPay Network's economics reward adoption rather than penalizing low usage the way a flat subscription would. If your accounting system is one of the property or fund-specific platforms AvidXchange integrates natively, Yardi, MRI, Rent Manager, or MIP Fund Accounting, that native depth is hard for an ERP-agnostic tool to match. And if you've done the diligence on the Corpay ownership stake and it doesn't concern you or your industry vertical's roadmap, that removes the one genuinely new variable in this comparison.

Decision Framework

What to Do Next

Before you book a call with either vendor, spend twenty minutes pulling three numbers: last month's invoice count, the ERP or vertical accounting system every entity in your company runs, and the rough percentage of vendor payments you could realistically move onto one payment rail this year. Bring those three numbers into the first sales conversation and ask for a quote broken out by module, not a single bundled figure, using the "what to demand in writing" checklist above as your script.

If your ERP is fixed and the pain is coordination rather than payments, start with Stampli and ask specifically how its dynamic approval workflows would map onto your current sign-off chain. If you're in real estate, HOA management, construction, financial services, or media, start with AvidXchange and ask how deep its native integration runs for your specific accounting system, since that depth is the entire argument for choosing a vertical platform over an ERP-agnostic one. And if either sales call leaves you wanting a published number to anchor against, our best AP automation software roundup for 2026 covers vendors like Tipalti and BILL that do post a starting price, alongside deeper looks at Stampli alternatives and Tipalti alternatives if neither of these two turns out to be the right fit.
