MVP scope, honest version: paste the invoice's text (from a PDF's text layer, email body, or any text source) below, or upload an actual PDF (OCR'd server-side via this account's own weyland-ocr-worker, no external OCR API). Either path runs the same real regex/heuristic field extraction -- vendor, invoice #, dates, line items, totals -- and produces a QuickBooks Bill-object-shaped draft for your review, matching QuickBooks' actual field names (VendorRef, TxnDate, Line[], etc). Neither path calls the QuickBooks API itself (needs real OAuth credentials this environment doesn't have).
