Each vendor row is taken from that vendor’s own pages, checked 2026-10-30; follow [source] for the page. "Not published" or "not mentioned" means the page did not say, not that the feature is missing. Aequo AP values come from our own pricing page and product.

Which tool fits which team?

There is no single best tool; the right one depends on your size, your accounting system and which part of the job is slow.

By job

You only need data out of documents, into your own system: Rossum or Nanonets.
AI coding and approvals on a large ERP: Vic.ai, Medius or Stampli.
Multi-location restaurants, clinics or grocery: Ottimate.
Bookkeeping capture: Dext.
AI capture plus PO matching on QuickBooks Online, Xero, FreshBooks, Zoho Books or Business Central: Aequo AP or Yooz.

Accuracy and automation claims, in each vendor’s own words

Every AI vendor publishes a headline number. These are the vendors’ own claims, measured their own way; we have not tested them, so ask for results on your invoices.

Vic.ai: "99% invoice accuracy without coding or setup" and an 85% no-touch rate by month 6. [source: Vic.ai home page]
Medius: 96.3% touchless processing for PO invoices and 99.5% for non-PO invoices. [source: Medius, why Medius]
Rossum: "up to 100% touchless". [source: Rossum, accounts payable]
Nanonets: 95% straight-through processing. [source: Nanonets, accounts payable]
Stampli: its AI agent Billy performs on average 89% of the work. [source: Stampli home page]
Dext: over 99% extraction accuracy. [source: Dext home page (US)]

Claims are not comparable with each other: some measure field accuracy, others the share of invoices no one touches.

Known limitations of each tool

Every tool here has gaps, Aequo AP included. Each limitation below comes from the vendor’s own pages, or from what those pages leave out.

Vic.ai: No published price or self-serve trial, and QuickBooks and Xero are not named among its integrations [source: Vic.ai, ERP integrations]
Ottimate: No published pricing, and its positioning centers on hospitality, healthcare and grocery [source: Ottimate home page]
Rossum: Starter is capture only: duplicate detection and ERP integration start at the quote-only Business tier, and approvals and GL coding are add-ons [source: Rossum pricing]
Nanonets: ERP integrations need the quote-only Growth plan, and per-invoice cost depends on how many blocks a workflow runs [source: Nanonets pricing]
Stampli: No published prices or trial; buying runs through a quote request, and Xero is not on its ERP list [source: Stampli pricing]
Yooz: No US price is published, and which edition includes PO matching and payments is not stated [source: Yooz pricing (US)]
Medius: Quote only with no trial; AP Essentials covers one entity, and Copilot and the supplier portal are only in AP 360 [source: Medius pricing]
Dext: A capture tool: its pricing page describes no purchase orders or matching, and extraction stops at the monthly document limit [source: Dext business pricing (US)]
Aequo AP: Does not pay vendors yet (coming soon); Oracle NetSuite and Sage Intacct are early access only; no PO approvals or procurement; prices are in US dollars

What it costs: a worked example for 500 invoices a month and 5 people who approve them

Extraction platforms price by usage and charge extra for workflow and integrations; full AP suites are mostly quote only. Compare the cost of the whole workflow, not just extraction.

Monthly subscription cost for 500 invoices a month and 5 people who approve them, from published prices
Tool	Monthly cost at this volume
Vic.ai	Quote only [source: Vic.ai pricing link]
Ottimate	Quote only [source: Ottimate home page]
Rossum	From $1,500 a month ($18,000 a year for Starter, which is capture only) [source: Rossum pricing]
Nanonets	Not published as a monthly price: metered per block run, with ERP integrations on the quote-only Growth plan [source: Nanonets pricing]
Stampli	Quote only [source: Stampli pricing]
Yooz	Not published (priced by document volume) [source: Yooz pricing (US)]
Medius	Quote only [source: Medius pricing]
Dext	Not published at this volume: the listed $25.21 a month (billed annually) covers 250 documents and 5 users [source: Dext business pricing (US)]
Aequo AP	$699 a month on Growth (up to 1000 documents, 3-way matching), the same for 5 approvers or 50

List prices only, before discounts, taxes and implementation. “Quote only” and “not published” mean the vendor does not publish a price; ask for one at your volume. Payment fees apply only if you pay vendors through the tool.

When is Aequo AP not the right fit?

In these cases another tool on this page, or your accounting system on its own, is the better choice.

You need extraction only, delivered by API into your own system. An extraction platform such as Rossum or Nanonets is the closer fit.
You need a generally available connector for an ERP other than QuickBooks Online, Xero, FreshBooks, Zoho Books and Business Central. Oracle NetSuite and Sage Intacct are in early access for selected teams, and Acumatica, SAP Business One and QuickBooks Desktop are in development.
You want one tool that also pays vendors today. Aequo AP vendor payments are coming soon; until then you pay approved bills from your accounting system or bank.

Frequently asked questions

What is the best AI invoice processing software?

For extraction alone, Rossum and Nanonets are document AI platforms with published entry prices; Vic.ai, Ottimate, Stampli, Yooz and Medius put AI inside a full AP workflow, and Dext uses it to capture bills for bookkeeping. Aequo AP uses AI to extract and code invoices, then matches them to purchase orders before approval.

What does AI do in invoice processing?

It reads invoices without templates (supplier, dates, line items, tax and totals), suggests GL coding from past invoices and your chart of accounts, matches lines to purchase orders, flags likely duplicates and unusual amounts, and in some tools suggests or routes approvers.

Is AI invoice processing accurate enough to skip review?

Vendors publish high figures, but they measure different things. Keep a person on exceptions, new vendors and anything that fails matching, and let clean, matched invoices flow through. Test on a sample of your own invoices first.

What is the difference between OCR and AI invoice processing?

Traditional OCR turns an image into text, often using a template per supplier. AI processing understands the layout without templates, pulls out line items and suggests coding and matches, so it copes with new suppliers and formats.

Which AI invoice tools publish prices?

Rossum (Starter from $18,000 a year), Nanonets (per block run, Starter $100 a month), Dext (from $25.21 a month billed annually) and Aequo AP (from $199 a month). Vic.ai, Ottimate, Stampli, Medius and Yooz in the US are quote only.

Automate matching, approvals and exception handling

Aequo AP captures invoices, matches them to purchase orders and receipts, routes approvals and flags duplicates and exceptions, then syncs with QuickBooks Online, Xero, FreshBooks, Zoho Books or Business Central.
