Zovo Invoice Reader

Use this when the user attaches 1 to 20 invoice PDFs and wants them in a spreadsheet, wants invoice data extracted (vendor, invoice number, invoice date, due date, subtotal, tax or VAT or GST, shipping, discount, total, amount due, line items), or wants the invoice arithmetic checked. Returns one Excel workbook (Invoices and Line items sheets) and a ZIP of CSV files, plus per-invoice checks: lines add up to the subtotal, subtotal - discount + tax + shipping = total, quantity x unit price = amount. Each check is PASS, MISMATCH with the difference, or NOT CHECKABLE when a value is missing. Text-based PDFs only (no OCR), up to 10 MB and 20 pages per file. Does not pay, approve, or send invoices. Do not use for receipts photographed with a phone or for making a new invoice.

Use this when the user types or pastes invoice amounts (line quantities, unit prices, line amounts, subtotal, discount, tax, shipping, total) and wants to know whether the invoice adds up. Returns PASS, MISMATCH with the difference in cents, or NOT CHECKABLE when a value is missing, for three checks: lines add up to the subtotal, subtotal - discount + tax + shipping = total, quantity x unit price = amount. Uses integer cent math. Does not read files (use read_invoices for PDFs), does not compute tax rates, and does not pay or send anything.
