Use cases / Document & invoice intake
Use case
Accounts payable automation — and the step the tools skip.
Plenty of software will read an invoice for you. Here's a fair look at the real options, the gap none of them close — reading a document isn't checking it — and what a system that does both looks like.
The real options.
AP automation software captures supplier invoices and receipts — snapped, emailed or uploaded — extracts the details, and posts them into your accounts package. For the firm whose paperwork is a steady flow of standard bills, one of these is exactly the right answer.
| Tool | Known for | Typically best for |
|---|---|---|
| Dext | Receipt & invoice capture with AI extraction | Small firms and their accountants |
| AutoEntry | Document data entry into accounting packages (by Sage) | Practices and SMEs feeding a ledger |
| ApprovalMax | Approval workflows before anything is paid | Firms on Xero/QuickBooks needing sign-off controls |
| Lightyear | Purchasing + AP with multi-level approvals | SMEs with real purchasing volume |
| Xero — built in | Smart document capture, included on all UK small-business plans | Anyone already on Xero |
| QuickBooks — built in | Snap or email receipts and bills, matched to transactions | Anyone already on QuickBooks |
| FreeAgent | UK accounting with built-in capture; free with some business bank accounts | Contractors and micro-businesses |
A snapshot, not a ranking — features and pricing change, so check current specs. Two notes: you may already be paying for this — Xero, QuickBooks and FreeAgent all include capture, so switch it on before buying anything. And if a steady flow of supplier bills into a ledger is your whole problem, one of these fits; buy it, and we'd help you wire it in. (Mid-market suites — Stampli, Tipalti, Basware, Medius — exist too, but they're built and priced for much bigger finance teams.) This page is for the firms the capture tools don't quite fit.
Where the capture tools stop.
Capture tools do one job well: a bill becomes a ledger entry without typing. The wall is everything around that job:
- Reading isn't checking. Extraction is probabilistic — a misread total or a transposed reference flows into your ledger looking exactly as confident as a correct one. The checking still happens later, by a person, at reconciliation — or it doesn't happen at all.
- Bills are only half the paperwork. Orders written in the body of an email, delivery notes, remittance advices, supplier price lists — the documents that actually run your week don't fit the bill-to-ledger pipe, so they stay manual.
- The data stops at the ledger. The same invoice details still get retyped into the job system, the stock system, the spreadsheet that prices next month — the re-keying survives, one step downstream.
- The pricing meters your growth. Capture tools sell document volume — credits per invoice processed — so the bill climbs precisely as your paperwork does.
The cost of standing still
The paperwork is about to change shape anyway.
Capture tools stop where your intake's real needs begin — and the timing matters. Three numbers worth sitting with:
Mandatory e-invoicing is coming: from 2029, the UK will require all VAT invoices to be issued as e-invoices — announced at Budget 2025, with the implementation roadmap due at Budget 2026. Meanwhile HMRC's own research finds 95% of small and medium-sized firms still send invoices as PDFs or email attachments, and just 9% mainly e-invoice. Nearly every VAT-registered firm's paperwork will have to change shape. (HMRC/DBT, 2025) (HMRC research, 2026)
Invoice and mandate scams — a criminal posing as a supplier and redirecting a genuine payment — cost UK victims £41.3m in 2025, and 68% of it, £28m, left business accounts, where payments are larger and a fraudulent one is harder to spot. Less than half the money was recovered. (UK Finance, 2026)
The error rate the government's own e-invoicing consultation put on manually entered supplier invoice data. Keying at speed produces mistakes — and a mistake found at reconciliation, or by a supplier's statement, costs many times the keystroke it came from. (HMRC/DBT consultation, 2025)
What we'd build instead.
An intake for how your paperwork actually arrives, with the step the capture tools skip built into the middle of it. Shaped to your firm, live in weeks, yours to own:
Intake that reads everything
Supplier invoices, orders written in the body of an email, delivery notes, photographed dockets — AI reads each one and turns it into a structured record, whatever shape it arrived in.
Checked, not just captured
Every figure verified with deterministic maths — totals re-added, VAT re-computed, quantity times price re-checked, duplicates caught, details compared against the order. A person sees the one document that fails a check, not the ninety-nine that pass.
A tripwire on bank details
Any invoice where the supplier's payment details differ from the details on record is quarantined until a person confirms the change through a channel they already trust — the procedural defence against the £28m problem above.
Landing where the work happens
The verified record flows to the ledger and the job, stock or pricing system in one pass — entered once, everywhere. And when the 2029 e-invoicing rails arrive, an intake you own adapts to the new format; it wouldn't need replacing.
Every one is a capability we can build now with AI-assisted development — not a promise your firm needs all of it. We start with the document that wastes the most of your week.
Where we've done it
We've built exactly this discipline.
Read-then-verify is how we build all document intake, and it's in production at scale: a UK firm's operating platform we built reads bank statements and financial documents with AI and verifies every line with deterministic checks before anything is accepted — people only ever see what doesn't balance.
Fair questions
What firms ask us about intake.
Can accounts payable be fully automated?
The reading, checking and matching can be. The judgement shouldn't be. A well-built system captures every document, verifies every figure with deterministic checks, and matches invoices to orders and payments on its own — then queues the handful that fail a check for a person, and leaves payment sign-off human by design. Full automation of the routine, none of the authority.
Is OCR accurate enough to trust for invoices?
Reading is probabilistic — every capture tool misreads sometimes. The trust shouldn't come from the reading; it should come from what happens after: totals re-added, VAT re-computed, quantities times prices re-checked, duplicates caught, the figure compared against the order. A system that proves each number, and asks a person when it can't, is trustworthy in a way raw extraction never is.
What's the best AP automation software for a small UK firm?
For standard supplier bills into a ledger: Dext or AutoEntry for capture, ApprovalMax if you need approval controls, Lightyear if you have real purchasing volume — and often the capture already included in Xero, QuickBooks or FreeAgent is enough. If one of those fits how you work, use it. The question changes when your intake is more than bills-into-ledger.
I'm on Xero or QuickBooks — don't I already have this?
Probably, yes. Xero includes smart document capture on all its UK small business plans, QuickBooks includes receipt and bill capture with a subscription, and FreeAgent is free with certain business bank accounts. Switch it on and use it. The custom case starts where those stop: verifying what was read, handling documents that aren't bills, and landing the data in more systems than the ledger.
How much does custom document intake cost?
It's a monthly retainer, not a big up-front project — tiers from £2,500 to £6,500 a month, with a free process audit first and an optional fixed-price discovery sprint credited against month one. You own the code and the data from day one.
