An honest comparison of the AP automation tools US finance teams actually shortlist, with published pricing where vendors publish it and a plain note where they do not. Every one of them starts by reading your invoices, so upload a bill below and see the data capture step for yourself before you book a single demo.

Accounts payable automation covers several different jobs, and vendors use the same words for very different products. A tool that captures invoice data is not the same as a tool that pays vendors, and neither is the same as a tool that routes approvals. Most shortlists go wrong at this step.
Stampli and AvidXchange publish no pricing at all, and Tipalti publishes only a starting platform fee. You cannot build a budget from a demo request, so comparing real cost means running the same volume past several sales teams.
Some teams only need invoice data pulled into their ledger. Buying a full payment rail to solve a data entry problem means paying for approval routing, virtual cards, and vendor onboarding you will never switch on.
BILL charges per user per month. If a dozen budget holders need to approve invoices, a per-user model costs far more than the AP clerks alone would suggest, and the quote you saw does not reflect it.
Header capture (vendor, date, total, invoice number) is standard. The line-item table, the part that matters for GL coding and spend analysis, is frequently metered, credited, or missing entirely.
Ignore the feature grids for a moment. Four things decide whether a tool fits: what it captures, what it does after capture, how it prices, and what it connects to.
Does the tool read the full line-item table (description, quantity, unit price, amount) on every document, or only the header fields? Header-only capture leaves the coding work on your desk.
BILL, Tipalti, Melio, Ramp, and AvidXchange move money. Dext and InvoiceExtractor do not. Deciding which half of the problem you have removes most of the shortlist immediately.
Per user, per month, per invoice, or per transaction. Approver-heavy teams and high-volume teams get very different answers from the same list price.
Native two-way sync with QuickBooks, Xero, NetSuite, or Sage Intacct, or a clean CSV or JSON file you import yourself. Both work. One locks you in, one does not.
A shortlist you can defend, without sitting through six demos first.
Write down whether the pain is keying invoice data, chasing approvals, or paying vendors. Most teams say all three and mean the first one.
Take your ten worst invoices, the scanned ones with long line-item tables, and run them through each tool. Accuracy on clean PDFs tells you nothing.
Tip: Upload one of those invoices here first. It is free and takes under a minute.
Multiply out per-user, per-invoice, and per-transaction fees at the volume and headcount you actually have, not the plan tier that looks cheapest.
The right answer changes completely with company size and where the bottleneck sits.
Melio and Ramp both have genuinely free tiers that pay bills. If the goal is to stop writing checks, start there rather than with an enterprise suite.
BILL and Stampli are built around routing and approvals. Expect per-user cost at BILL and a sales call at Stampli.
Tipalti handles multi-entity, multi-currency payouts and supplier tax onboarding. That is what the platform fee buys.
If approvals and payments already work and the pain is data entry, a focused extractor gets invoice fields and line items into Excel, CSV, JSON, or an API without a new platform.
There is no single best AP automation software, because the category covers three different jobs. BILL and Stampli are strongest for approval routing in mid-market teams. Tipalti fits global, multi-entity payouts. Ramp and Melio offer genuinely free tiers for small businesses that mainly need to pay bills. Dext and InvoiceExtractor do not pay vendors at all; they capture invoice data. Pick by the job you have, not by the longest feature list. Last updated July 2026.
A disclosure first, because it matters when you read the table below. InvoiceExtractor publishes this page, and InvoiceExtractor is in the comparison. We are a data capture tool. We do not route approvals, we do not pay vendors, and we do not issue checks or ACH. For a large share of the people searching for AP automation software, one of the other tools on this list is the correct purchase. The table says so where it is true.
Pricing below is each vendor's own published US list pricing, checked in July 2026. Where a vendor publishes nothing, the table says so rather than guessing. Vendor pricing moves, so confirm on the vendor's page before you commit.
| Tool | Published US pricing (July 2026) | Pays vendors | Best for |
|---|---|---|---|
| BILL (Bill.com) | Essentials $49, Team $65, Corporate $89 per user/month; Enterprise custom | Yes | Mid-market AP with real approval chains |
| Tipalti | AP plans from $99/month platform fee; most pricing quoted | Yes | Global, multi-entity, mass payouts |
| Stampli | None published, quote only | Yes | Approval collaboration on the invoice itself |
| Ramp | Free $0/user/month; Plus $15/user/month plus platform fee; Enterprise custom | Yes | Card spend plus AP in one place, free tier included |
| Melio | Go $0 (one user); Core $25; Boost $55; Unlimited $80 per month; Platinum custom | Yes | Small businesses that mainly need to pay bills |
| AvidXchange | None published, quote only | Yes | Mid-market, industry-specific AP (real estate, construction) |
| Dext | Business from about $31.50/month; Practice from about $239/month | No | Bookkeepers capturing client documents into a ledger |
| InvoiceExtractor | Free to try, usage based | No | Getting invoice fields and line items into Excel, CSV, JSON, or an API |
Published entry points in July 2026 run from $0 per month (Ramp Free, Melio Go) to $49 per user per month (BILL Essentials) and $99 per month as a platform fee (Tipalti AP). Stampli and AvidXchange publish nothing and quote per deal. Add per-transaction fees for ACH, checks, and wires on any tool that moves money, because those rarely appear in the headline price.
The number that matters is cost at your volume and headcount. A ten-approver team on BILL Essentials pays $490 a month before a single payment fee. The same team on Melio Unlimited pays $80. They are not the same product, but the gap is worth understanding before the demo, not after.
Yes, with limits. Ramp's Free plan is $0 per user per month and includes AI invoice capture with OCR plus bill payment by check, ACH, card, and wire. Melio's Go plan is free forever but caps you at one user. Both hold back the deeper AP features, such as automated batch payments and line-item auto-coding, for paid tiers. Free tiers are real here, not trials.
In practice the terms are used interchangeably by vendors, but there is a useful distinction. Accounts payable software is the ledger side: it records what you owe and to whom. AP automation is the workflow around it: capturing the invoice, coding it, routing approvals, and releasing payment. Most modern tools sell both. Read our accounts payable automation software page for how the workflow layer works end to end.
For a small business paying under a few hundred bills a month, start with Melio or Ramp. Both have free tiers that genuinely pay vendors, and neither charges per approver. Move up only when approval routing or multi-entity accounting forces it. We cover the trade-offs in more depth on our accounts payable software for small business page.
QuickBooks Online includes bill capture: upload a PDF, JPEG, JPG, GIF, or PNG and it extracts information to pre-fill a bill transaction. It handles the header fields well. Multi-line invoices commonly still need the line-item table keyed by hand, which is where a dedicated extractor earns its place. See QuickBooks AP automation, and the equivalents for Xero, NetSuite, and Sage Intacct.
Answer three questions in order. Is the bottleneck data entry, approvals, or payment? How many people need to touch an invoice? Which ledger must it sync with? The first answer eliminates most of the market. If data entry is the bottleneck and your approvals already work, you probably need extraction rather than a platform, and you can test that in a minute with the tool at the top of this page.
BILL has the deepest mid-market approval workflow and the widest accountant network. Tipalti is the serious answer for paying suppliers across countries and entities, with tax and compliance onboarding built in. Stampli puts the conversation on the invoice itself, which resolves approval arguments faster than email ever will. Ramp bundles corporate cards and AP, so spend and bills sit in one ledger. Melio is the cheapest honest way for a small business to stop writing checks. AvidXchange knows real estate and construction AP better than generalists do.
InvoiceExtractor wins on one axis only: getting complete, structured invoice data out of any layout, including the full line-item table, into a format you control. That covers AP teams whose approvals work fine and whose real cost is keying, analysts pulling invoice line item extraction into a warehouse, and developers who want an invoice data extraction API rather than a platform. If you need to pay vendors, buy one of the tools above and let extraction feed it.
Comparing capture tools specifically rather than payment platforms? The best invoice data extraction software roundup covers Nanonets, Docparser, Rossum, Docsumo, Mindee, and the cloud OCR APIs, and our Dext alternative page goes deeper on bookkeeping capture.

It depends on the job. BILL and Stampli lead on approval routing for mid-market teams. Tipalti fits global multi-entity payouts. Ramp and Melio offer free tiers that pay bills, which suits small businesses. Dext and InvoiceExtractor capture invoice data but do not pay vendors. Choose by bottleneck, not by feature count.
AP automation software handles the accounts payable workflow with less manual work: capturing invoice data from PDFs and scans, coding it to the general ledger, routing it for approval, and releasing payment. Some tools cover the whole chain, while others specialize in one step, most commonly data capture or payment execution.
Published US entry prices in July 2026 range from $0 per month (Ramp Free, Melio Go) to $49 per user per month (BILL Essentials) and $99 per month platform fee (Tipalti AP). Stampli and AvidXchange do not publish pricing and quote per deal. Payment fees for ACH, checks, and wires usually sit on top.
Yes. Ramp offers a $0 per user per month plan that includes AI invoice capture and bill payment by check, ACH, card, and wire. Melio's Go plan is free forever but limited to one user. Advanced features such as batch payments and line-item auto-coding require paid tiers on both platforms.
Melio and Ramp are the usual starting points for small businesses, because both have free tiers that actually pay vendors and neither charges per approver. Step up to BILL when approval chains grow, or add a dedicated extractor if the real cost is keying invoice line items rather than paying them.
Accounts payable software records what you owe and to whom, on the ledger side. AP automation is the workflow around that record: invoice capture, GL coding, approval routing, and payment release. Vendors use the terms interchangeably, and most modern platforms now sell both layers together.
QuickBooks Online includes bill capture. Upload a PDF, JPEG, JPG, GIF, or PNG and QuickBooks extracts information to pre-fill a bill. It reads header fields such as vendor, date, and total reliably. Multi-line invoices commonly still need the line-item table entered by hand, which is where a dedicated extractor helps.
Decide first whether your bottleneck is data entry, approvals, or payment, because that removes most of the market. Then count how many people must touch an invoice, since per-user pricing punishes approver-heavy teams. Finally check the native integration for the ledger you actually run, or accept a CSV import.
