Invoice-to-pay automation
Invoices arrive in every format and get re-keyed by hand. Automate capture, matching and posting, and keep people on the exceptions only.
Why this workflow costs more than it should.
The problem
Invoices arrive as PDFs, scans and email bodies in many formats. People re-key them into the ERP, chase approvals and resolve price or quantity mismatches by hand. Invoices take an average of 8.2 days to process, and AP staff spend 21.9% of their time answering supplier questions1.
Integration footprint
- Input: AP inbox or supplier portal
- System of record: accounting or ERP API (e.g. Xero, QuickBooks, NetSuite, SAP Business One)
- Match data: purchase orders and goods receipts
- Approvals: Slack, Teams or email
- No rip-and-replace: the ERP stays the source of truth
Five steps, one human checkpoint.
The agent does the repetitive work. People decide the exceptions. Every action is logged against the baseline.
Capture every invoice
Watch the AP inbox and portal. De-duplicate and log each document.
Read header and lines
Pull supplier, amounts, VAT and line items, with a confidence score for each field.
2- and 3-way match
Check against the PO and receipt. Flag price, quantity and duplicate exceptions.
Exceptions only
Low-confidence items and mismatches go to a reviewer with the evidence attached.
Post to ERP, log
Create the bill, route it for approval and write an audit trail for every action.
What your team works in.
One screen for the queue, the evidence and the decision. Exceptions come with the reason and a suggested action, so reviewing one takes seconds.

What it could be worth.
Mid-size company, 2,000 invoices a month
Baseline uses the Ardent average cost per invoice. The scenario assumes automation halves the cost per invoice. That is well short of the 79% gap Ardent reports between best-in-class teams and their peers.
| Annual volume | 24,000 invoices |
| Baseline × $9.84 | $236,160 / yr |
| Scenario: −50% cost / invoice | $118,080 / yr |
