Accounts payable is one of those jobs where the work is dull and the mistakes are expensive. Someone types the invoice in, checks it against the purchase order, chases the right person for approval, and posts it before the terms run out. Do that a thousand times a month and something slips: a duplicate payment, a missed early payment discount, a unit price that quietly went up in March.
So I built Ledgerpilot, an accounts payable system that handles the routine invoices end to end and asks for a person only when it should.
An invoice arrives by email, supplier portal or EDI. The system reads it, checks every line against the purchase order and the delivery note, looks for duplicates across the last six months, then applies the company rules before it goes into the accounting system.
Three things I cared about while building it.
The person gets evidence, not a verdict. When an invoice needs review, the screen shows the scanned document with every field the AI read marked on it, how sure it was about each one, the line by line comparison against the order, and a note on what it recommends and why.
Policy comes before confidence. Rules like "over $10,000 goes to the controller" or "new supplier, first three invoices" run first. A confident read never lets an invoice skip the person who is supposed to sign it.
You can change the rules and see the effect before you save. Move a threshold and the screen tells you how many of the last 30 days of invoices would have gone through on their own.
The front end is React and TypeScript. The backend is designed around .NET and Node.js services, RabbitMQ, PostgreSQL and AWS, with queue depth, worker health and cost per document visible in the app.
I built this as a portfolio project with realistic sample data, not a client system, so the thinking is mine to show: the flow, the screens and the checks around the AI.
If your finance team is buried in invoices and you want automation your auditor will be happy with too, I am glad to talk it through.
It runs 23 characters over 2,000. Cut the words "and the mistakes are expensive" from the first line and it lands at 1,993. I left it in because it earns its place in the hook, and most feeds allow more than 2,000.
