By use case: Invoice processing
Invoice processing automation, from inbox to ledger.
Supplier invoices read as they arrive, matched to the order and the goods received, approved by the right person and posted to your accounting system. People only see the ones that do not match.
- First workflow live
- Invoice capture from email, usually inside the first sprint
- Usually owned by
- Accounts payable clerks and bookkeepers
- Built on
- Xero, QuickBooks, Zoho Books / Tally
- Judged on
- Touchless rate and Cycle time
In short
Invoice processing automation reads each supplier invoice from the inbox, extracts supplier, amounts, tax and line items with AI, matches them to the purchase order and goods receipt, routes exceptions and approvals to the right person, and posts the bill to your accounting system. Anything below a confidence threshold goes to a person, not the ledger.
Who this is for
The people who usually own invoice processing.
- Accounts payable clerks and bookkeepers
- Finance managers and controllers
- Founders who approve every bill themselves
- Operations leads who receive the goods
Is this you?
If three of these sound like your week, this page is about your team.
- Someone types supplier invoices into the ledger every week
- Approvals happen by forwarding emails
- You cannot say where a given invoice is right now
- Suppliers chase you for payment status
- You have paid the same invoice twice at least once
What it costs today
Where invoice processing loses the hours.
Invoices arrive in every format
PDFs, scans, photos and emails with the amount in the body. Someone opens each one and types it into the ledger.
Matching happens by eye
Checking the invoice against the purchase order and what actually arrived is done line by line, or skipped when the month is busy.
Approvals stall in inboxes
The invoice waits for a manager who is travelling, nobody can see where it is, and the supplier calls to ask.
Duplicates and errors slip through
The same invoice sent twice, a price that changed since the order, or the wrong tax code. Found at month end, if at all.
For accounts payable
Type the exceptions, not the invoices.
Send us last month’s invoices. We will show you which would have passed untouched, which would have stopped, and why.

A bookkeeper typing every invoice, approvals by forwarded email.
- 51 to 200
Hundreds of invoices a month, purchase orders in one system and receipts in another, matching done by sampling.

Several entities and approvers, a payables team keying invoices, and duplicate payments found only in audit.
What we build
What we build for invoice processing teams.
- 01
Inbox capture and AI extraction
A dedicated accounts payable inbox watched by an automation. An AI step reads each invoice and returns structured fields with a confidence score for each one.
- 02
Two and three-way matching
Deterministic rules compare the invoice to the purchase order and goods receipt, within the tolerances you set. Matches pass, differences become exceptions with the reason attached.
- 03
Approval routing
Approvers chosen by amount, cost centre and supplier, with reminders, delegation when someone is away, and a full record of who approved what.
- 04
Exception queue and ledger posting
A small internal tool where the finance team clears exceptions in one place. Approved bills are posted to the ledger through its API with the original document attached.
The workflows
The invoice processing workflows, and what sets each one off.
- 01 Invoice capture from email

- 02 Three-way match

ThenCompared to purchase order and goods receipt within tolerance
- 03 Invoice approval routing
When match passed or exception cleared
ThenSent to the approver for that amount and cost centre
- 04 Post to ledger
When invoice approved
ThenBill created in the accounting system with the PDF attached
- 05 Duplicate check
When any new invoice
ThenChecked against supplier, number, date and amount before it moves on
The numbers we move
How a invoice processing build is judged.
Every build has a number written into the blueprint. These are the ones invoice processing builds are measured by, and how we measure them.
| Metric | Before | After | How it is measured |
|---|---|---|---|
| Touchless rate | Every invoice typed | Most pass without a person | Share of invoices posted with no manual edit, weekly |
| Cycle time | Days or weeks | Same or next day for clean invoices | Time from invoice received to posted and approved |
| Exceptions | Found at month end | Listed with a reason on arrival | Open exceptions by reason and age |
| Duplicates caught | Found in audit | Blocked before posting | Invoices flagged as duplicates by supplier, number and amount |

How it starts
An audit of the invoice processing work your team still does by hand.
One to two weeks. We map the workflows, put an hours-a-week figure on each, and give you a costed blueprint in order of payback. The audit is credited in full to the build.
- Week 1 to 2Audit. We sit with the people who do the work and map it.
- Week 3Blueprint. Fixed scope, fixed price, the first build chosen by payback.
- Week 4 onBuild in two-week sprints, working software every second Friday.
- After go-liveSixty days of hypercare, then a care plan or run it yourself.
What this does not do
So the scope is clear before the call.
- Making payments. We prepare and post bills; releasing money stays with your team and your bank.
- A handful of invoices a month. Below a few dozen, a good template and a shared inbox is cheaper than a build.
- Replacing your accounting system. It stays the ledger.
Terms, defined
Invoice processing terms, in plain English.
- Three-way match
- Checking that the invoice, the purchase order and the goods receipt agree on items, quantities and prices before paying.
- Touchless invoice
- An invoice captured, matched, approved and posted without anyone editing it.
- Tolerance
- The difference in price or quantity you accept before an invoice becomes an exception.
Questions
What people ask about invoice processing automation.
How accurate is AI invoice extraction?
Accurate enough to remove most of the typing, not accurate enough to trust blindly. Every field carries a confidence score, and anything below the threshold, or anything that fails a match, goes to a person before it reaches the ledger. During the first weeks we review every extraction with your team and tune the thresholds on your real invoices.
Do we need purchase orders for this to work?
No. Without purchase orders the build matches against supplier, expected amounts and recent history, and relies more on approval routing. With purchase orders and goods receipts it can do full three-way matching. Our guide to automating accounts payable (/guides/how-to-automate-accounts-payable/) walks through both.
Which accounting systems can it post to?
Xero, QuickBooks, Zoho Books, Sage, NetSuite and Tally, among others. Bills are posted through the system’s own API with the document attached, so the ledger stays the system of record.
What does it cost?
Capture, extraction and posting between one inbox and one ledger is around $2,500. Adding matching, approval routing and an exception queue usually lands between $5,000 and $15,000. The guide on what AI automation costs (/guides/how-much-does-ai-automation-cost/) explains how we price it, and the ROI calculator (/tools/roi-calculator/) helps you check it against the hours you spend today.

How much should an AI agent be allowed to do?
An agent with an unscoped token dropped a production database and its backups in nine seconds. Our rule: read widely, write narrowly, cap spend, escalate.
