How to automate invoice processing without new software

Every invoice that lands in your inbox has to be opened, read and typed somewhere. Supplier, invoice number, date, due date, net, tax, total. Sometimes line items too.

Each one only takes a few minutes. The trouble is they never stop, and the person doing it is usually someone whose time is worth more elsewhere.

Then there are the typos. A transposed digit in a total, a duplicate entered twice, a due date missed. None of it is dramatic on the day. It all shows up at month end, when someone has to find it.

When I build one of these, it nearly always follows the same shape.

1. Watch the place invoices arrive: a shared inbox, a Google Drive or OneDrive folder, or a supplier portal.
2. When a new invoice comes in, AI reads the PDF or photo and finds the fields you care about.
3. Run checks: does the total add up, is the supplier known, has this invoice number been seen before, is the VAT sensible.
4. If everything passes, save the data to your sheet or accounting software and file the original.
5. If something fails, flag it for a person with a clear note on what looked wrong.

The AI part is reading the document. Everything around it is plain, predictable rules. That mix is what makes it reliable.

Yes. This is the bit that changed in the last few years. Older tools needed a template for every supplier layout, and broke the moment a supplier redesigned their invoice.

AI reads a document more like a person would. It understands that “Amount due”, “Total payable” and “Balance” are probably the same thing, even if they sit in different corners of the page.

It isn't perfect. Blurry phone photos and handwritten notes are harder. That's exactly why the checks and the human review step exist.

Anything unusual is flagged, never guessed. Typical flags look like this:

• A supplier you've never paid before.
• Line items that don't add up to the total.
• An invoice number that looks like a duplicate.
• A missing field, such as no due date or no VAT number.
• An amount well above what that supplier normally charges.

A person looks at those, fixes or approves them with a click, and the rest flows through on its own. You stay in control of what gets paid. The automation just does the typing.

The automation does the typing. You still decide what gets paid.

The same pattern works for orders, delivery notes, receipts and purchase orders. If it's a document with numbers that someone types up, it's a candidate.

No. We connect to what you already have: Gmail or Outlook, Google Sheets or Excel, your cloud storage and your accounting software. Your team keeps working where they already work.

If someone on your team types invoices or orders by hand every week, the answer is usually yes. If you get three invoices a month, probably not yet, and we'll say so.
