Purchase invoices with AI from file: less typing, fewer reworks

Why it matters: fewer reworks, fewer wasted hours

On site, purchase invoices arrive as PDFs, WhatsApp photos, supplier Excel files or e-invoice XML. Without the right tools, someone must open each file and copy vendor, number, date, items, quantities and prices —and do it again when a typo slips in.

That rework costs real time: admin, procurement or accounting hours that should go to validation, not typing. CoPres AI reads the document for you, proposes the invoice in the platform and leaves your team to do what actually adds value: review, fix if needed and approve.

Step 1: Click «Generate with AI» and choose «From file»

On the Purchase invoices screen, click «Generate with AI» at the top. A window opens with several options; choose «From file».

This option is perfect when you have a single document on your computer: a scanned invoice, the supplier PDF or stamped XML. No templates or forms —just the file as you received it.

Step 2: Select the file on your computer

Your computer asks you to pick the file. Find the invoice —PDF, phone photo, Excel or XML— and click Open.

This option handles one file at a time: one document equals one invoice. If several invoices are mixed in one PDF, the AI may get confused; split documents or use the multi-file option instead.

Step 3: Wait while AI analyzes the document

You will see «Analyzing document with AI…». The system is reading vendor, dates, line items, quantities and prices.

It usually takes a few seconds. Do not close the page while it processes. Large or multi-page files may take a bit longer, but it is still far faster than manual entry.

Step 4: Check the new invoice in the table

When finished, a new invoice appears in your table with the vendor, number and date it could read. If all went well, you will also see a green confirmation message.

That ends automatic entry: what used to be PDF on one screen and typing in Excel or the ERP is now validating what AI already brought in. Fewer reworks because data is captured once, in the same place where you approve and lock.

Step 5: Confirm products, quantities and prices

Open the invoice and review products, quantities and prices. AI helps, but you confirm —that human check prevents costly mistakes on site.

When it is correct, approve and lock the invoice. The flow is traceable: you know who validated and when, without intermediate spreadsheets or duplicate capture.

Before you finish, keep this in mind

To get the most from the feature and avoid reloading the same invoice because of preventable issues:

• One file equals one invoice. Mixed invoices in a single PDF confuse the AI.
• Works with PDF, sharp photos, Excel, CSV and e-invoice XML.
• Files can be up to 12 MB. Compress larger files first.
• Blurry photos or password-protected PDFs may fail. Try a clearer image.
• Always review numbers before approving; AI can occasionally miss a decimal.

CoPres AI in procurement: time back for your team

Digitizing purchase invoices should not mean hiring more people just to type data. CoPres AI turns each file into a structured draft inside the platform, aligned with the rest of your project controls.

Less manual entry, fewer capture errors and more time to negotiate with suppliers, reconcile stock and close months with reliable data. Try a real invoice from your job site and measure the minutes your team gets back.
