I will automate invoice extraction from pdfs with smart validation
About this Gig
Still copying invoice data from PDFs into Excel by hand?
I automate invoice extraction from digital or scanned PDFs into clean, structured Excel data using Python and OCR.
WHAT I EXTRACT:
- Vendor, invoice number, issue & due dates
- Customer, currency, subtotal, tax, and total
WHAT MAKES THIS DIFFERENT:
- Flags ambiguous dates (like 03/04/2026) instead of guessing
- Multi-currency support: USD, EUR, GBP
- Validates totals and flags missing fields
- Never silently guesses - uncertain values get flagged for your review
YOUR PACKAGE INCLUDES:
- Digital and scanned PDF processing
- OCR for image-based documents
- Structured Excel output with validation flags
- Separate review sheet for flagged records
- Custom fields and validation rules
Use cases: accounts payable, bookkeeping, document digitization, batch PDF-to-Excel automation.

FAQ
Can you process scanned or image-based invoices?
Yes. I can use OCR to extract data from scanned or image-based PDF invoices. Clear, high-quality scans usually produce the best results. If your documents are blurry, handwritten, or difficult to read, please contact me before ordering so I can review the files first.
What invoice data can you extract?
I can extract common fields such as vendor, invoice number, invoice date, due date, customer, currency, subtotal, tax, and total. If you need other fields, please send me a sample invoice and your required Excel columns before ordering.
How do you handle missing or incorrect invoice data?
I can apply validation checks for missing fields and inconsistent values, such as a total that does not match the subtotal plus tax. Questionable records can be flagged for review instead of silently guessing the correct value.
Can you process invoices with different layouts?
Yes, but the complexity depends on how different the layouts are. Standardized invoices are easier to automate, while multiple vendors or very different formats may require custom extraction rules. Please contact me with sample files first if you have many different layouts.
What do you need from me before starting?
Please provide your invoice files, the fields you want extracted, and your preferred Excel columns or format. If you have multiple invoice layouts, sending a few representative samples will help me confirm the scope and choose the right package.
How do you handle ambiguous dates like 03/04/2026?
I flag it for your review instead of guessing whether it means March 4 or April 3. If you tell me your date convention upfront (US or European), I apply it automatically and skip the flag. Dates where one number is over 12 resolve themselves and never get flagged.
