About this Gig
Looking for a developer who can turn your invoices and receipts into spreadsheet rows your team can review and use?
I build custom AI document OCR apps for businesses that want to spend less time on data entry. Each app is built around your document layouts, the fields you need, and where the data goes next.
What I deliver
- Document OCR Extract invoice numbers, dates, line items, and totals from scans and photos.
- Data validation Flag missing fields and totals that dont add up. Edit a value and the app reruns the checks immediately.
- Excel and JSON export Download a workbook with separate sheets for summaries and line items, or export structured JSON.
- Workflow automation Process documents from a folder, inbox, or API and send reviewed records to your database, CRM, or accounting software.
Every build includes testing on your sample documents, source code, and setup documentation so your team knows how to run it.
Tell me which documents you process and what the finished output should look like. Ill recommend the right approach and package for your workflow.

FAQ
Which documents and languages can you handle?
I build OCR workflows for invoices, receipts, ID cards, and business cards. If your files include PDFs, handwriting, tables, or multiple languages, send a representative sample with sensitive details removed. I’ll test it and confirm which fields the app can reliably extract before you order.
How do you check that the data is correct?
I compare the extracted values with your samples and expected output. Standard and Premium add checks tailored to your documents. For example, the app can flag a missing invoice number or a mismatch between quantity, unit price, and line total. You can correct a field and see immediately whether it
How will you handle my documents?
Redacted samples are usually enough to scope the project. Before you share live files, we’ll agree on where processing runs, which AI provider receives the images, who can access them, and when test files should be deleted.
What do I receive after delivery?
Every package includes the reusable app, source code, and setup instructions. You can keep processing new documents of the agreed type. Premium also includes deployment to your cloud and a walkthrough covering uploads, flagged records, and the connected system. You cover ongoing hosting and AI usage
What do you need from me to get started?
Send a few representative files, the fields you need, and an example of your desired output. A spreadsheet with one completed invoice is especially helpful because it shows whether you want one row per invoice or one row per line item.
