Handwritten whiteboard marker reads surprisingly well when the photo is clean. The meeting ends, someone erases the whiteboard, and the…
⚡ Quick Answer Free invoice workflow for small business: collect (scan paper, save emailed PDFs), batch-OCR with gImageReader, log key fields (number, date, vendor, total) in a spreadsheet, archive searchable PDFs by vendor and year. Honest note: free OCR won’t auto-extract line items — for that you need invoice-specific software (below). Freelancers and small businesses…
