How do I automate invoice data extraction when every vendor PDF has a different format?

Why invoice extraction is hard

Invoices rarely arrive in one perfect template. Vendors use different layouts, line-item tables vary, and important values can appear in headers, footers, or multi-page sections.

A simple OCR or copy-paste process may capture text, but it often does not produce the structured fields an AP or finance team needs.

What the workflow should do

A reliable invoice workflow should ingest files from email inboxes, portals, uploads, or shared folders, extract the same invoice fields across many vendor layouts, flag exceptions, and keep the final columns consistent.

For recurring AP work, the workflow should also support batch processing, duplicate checks, and export to the spreadsheet or finance system your team already uses.

How Lido helps

Lido helps teams define the invoice data they need, use AI to extract it, review results in a familiar spreadsheet-like interface, and automate the next step.

That combination is especially helpful when you need practical AP automation without building custom software from scratch.

Example workflow

1. Collect vendor invoice PDFs from email inboxes, portals, uploads, or shared folders.
2. Define the target fields or table columns: the same invoice fields across many vendor layouts.
3. Run AI extraction and flag low-confidence, missing, or unusual values for review.
4. Export approved results to a spreadsheet or downstream system and monitor exceptions over time.
