Best AP Automation Software for Business Central

Short answer: if you want AP automation that lives inside Business Central itself, Continia Document Capture is the closest fit, because it runs as an embedded app rather than a separate system. If you would rather keep the AP work outside the ERP and sync it back, Stampli and Tipalti both publish AppSource-certified two-way connectors for Business Central. AutoPayables handles the capture and line-level coding well and hands data back through a REST API, with an accounting sync still on the roadmap.

What Business Central already does for accounts payable

Business Central is a real AP ledger. It holds vendors, purchase invoices, purchase orders, payment terms, dimensions and the general ledger, it runs payment journals and suggests vendor payments, and it has an approval workflow you can switch on. None of that is missing.

What it does not do is read a supplier's PDF. Somebody opens the invoice, reads the vendor and the invoice number and the total, decides which G/L accounts and dimensions the lines belong to, and types it into a purchase invoice card. Microsoft's own answer to this is the incoming document feature, which can hand a file to an external OCR service, but you still get a document that a person has to finish and post. On a hundred invoices a month that is a day of somebody's week. On five hundred it is a job.

So the question is not really whether Business Central can do AP. It is which part of the typing you want to remove, and whether you want that to happen inside the ERP or beside it.

The four realistic options, compared

Every claim below was checked against the vendor's own product pages and Microsoft AppSource listings in August 2026.

BILL also publishes two-way syncs for QuickBooks, Xero, NetSuite, Sage Intacct and Microsoft Dynamics. Its Dynamics listing does not spell out which Dynamics products are covered, so if you are on Business Central specifically, ask them to confirm that in writing before you shortlist them. That ambiguity is common across the category and it is worth an email.

Inside the ERP or beside it? The decision that actually matters

This is the fork everything else hangs off, and there is no universally right answer.

Inside means one system, one login, one set of permissions, and dimensions that cannot drift because there is only one copy of them. Your auditors see one trail. Your BC partner can support it. The trade-off is that you are bound to the ERP's release cycle and to the pool of people who know both AP and Business Central, which is smaller than you think when someone leaves.

Beside means the AP tool evolves on its own schedule, non-finance approvers never need a BC licence, and you can switch it out later without touching the ERP. The trade-off is a sync you now have to trust. Every field that moves between two systems is a field that can disagree, and dimensions are the usual casualty.

A rough rule that holds up: if purchase orders drive most of your spend and matching is the bottleneck, staying inside wins. If the bottleneck is a hundred PDFs a month arriving in a shared mailbox in fifty different layouts, a specialist capture tool beside the ERP usually wins, and it wins faster.

Does Business Central have built-in AP automation?

Partly. Business Central includes vendors, purchase invoices, purchase orders, payment journals and an approval workflow, and the incoming documents feature can route a file to an external OCR service. What it does not include is accurate capture of a supplier's invoice with its line items coded to your G/L accounts and dimensions. That gap is what every product in the table above is selling into.

How much does Business Central AP automation cost?

Continia and Stampli both price by quote, and Business Central add-ons are commonly sold per user or by document volume through your Microsoft partner. Tipalti publishes Select at $99 a month and Advanced at $199 a month before per-payment fees. AutoPayables is free for 20 invoices a month, $49 a month for 200 on the Growth plan, and $149 a month for unlimited invoices plus REST API access on Scale. Ask every vendor whether approvers count as billable seats, because on some platforms an approver who only ever clicks yes is a full-price user.

What should you check before you buy?

Four things, in this order. First, does the connector move dimensions, not just G/L accounts? In Business Central the dimensions are usually where the reporting value lives, and a sync that drops them will quietly cost you the analysis you bought BC for. Second, is it two-way? A connector that only pushes invoices in cannot tell you a bill was already posted. Third, does the tool code line by line or only at the invoice header? Header-level coding looks fine in a demo and falls apart on a real invoice that splits across four accounts. Fourth, what happens on the payment itself: some platforms move money, others record that you paid. Both are legitimate, and they are very different contracts.

Where AutoPayables fits, honestly

We are not the right answer if automatic three-way matching against Business Central purchase orders is what you came for. We store purchase orders and their lines, but we do not match them automatically, and we do not have an accounting sync yet.

What we do well is the front of the process. Forward a supplier invoice to your intake address or upload it, and the AI pulls the vendor, invoice number, PO number, dates, currency, subtotal, tax, discount, shipping, total and every line item, with a confidence score stored against each field so you know what to check. Every line carries its own G/L account, which means one invoice can split across as many accounts as it needs instead of being flattened into a single expense code. Vendors hold tax ID, 1099 status, payment terms and a default G/L account. One approval threshold decides what a human sees, and every approval is written to a log. On the Scale plan the REST API lets you pull that structured data into Business Central yourself.

If capture accuracy and coding are your bottleneck, that is a cheap way to test whether automation helps before committing to a full ERP-embedded rollout. Our page on Business Central accounts payable automation goes deeper on the ERP side, and if you are still deciding between vendors, the comparison of automated accounts payable solutions lists what each one publishes. Teams evaluating the approval chain rather than the capture step should look at accounts payable workflow software, and anyone weighing the full end-to-end picture will find payables automation software covers it. If matching is genuinely the requirement, invoice matching software is the honest place to start.

One more thing worth saying out loud, because it comes up in nearly every Business Central conversation: BC handles the receivables side itself, and plenty of teams discover the real cash problem was never payables at all. If invoices going out are the ones sitting unpaid, software that chases every unpaid customer invoice by email and text automatically is a completely different purchase, and usually a more urgent one. Deciding which side actually hurts before you buy anything is the cheapest hour you will spend on this. Our breakdown of AP AR automation software covers which vendors cover both sides and which are payables only.
