AI invoice and document processing: the end of manual data entry

AI document processing recognizes data in a PDF, scan or photo, such as supplier, amounts, dates, line items and order number, and enters it into your system. For companies that retype hundreds of documents a month, it is one of the fastest-paying automations. A person still checks, but instead of typing, they only confirm.

Which documents AI can read

• Incoming invoices that arrive as PDFs or scans rather than structured e-invoices.
• Purchase orders and quotes from customers and suppliers, so line items become a job or quote in your system right away.
• Delivery notes and timesheets, including handwritten ones, with somewhat lower accuracy.
• Contracts, from which deadlines, amounts and obligations are extracted, with a summary for the owner.

What about e-invoices?

A structured e-invoice already contains data in a form a system can read directly, so AI is not needed for it. The problem is documents that still arrive as PDFs, scans or photos: invoices from smaller or foreign suppliers, purchase orders, delivery notes and contracts. That is where AI saves the most time. A well-designed system handles both: it reads e-invoices directly and lets AI process the rest.

How accurate is it?

On clean digital PDFs accuracy is very high. On poor scans, photos and handwriting it drops. That is why the system shows its confidence for each field: high-confidence data is entered automatically, and uncertain fields are flagged for review. Staff then check only what needs checking, not every document.

What the flow looks like

1. A document arrives at a dedicated email address or is uploaded to the system.
2. AI recognizes the document type and extracts the data.
3. The system compares it with what it already knows, e.g. whether the supplier exists and the order matches.
4. A staff member confirms or corrects the flagged fields.
5. The data moves on: to accounting, inventory or a job.

What it costs

Automating one document type, such as incoming invoices, connected to your system costs up to €5,000 with us. We build a working prototype on your real documents for €1,000, ready in 5 working days and credited to the build. The monthly AI service cost depends on document volume.
