Paste the source below the prompt or attach the stated file in a platform that supports it. Use authorized, non-sensitive data. This website does not send attachments to the AI platform.

Your prompt

Read the invoice lines I paste or attach. Extract description, quantity, unit price and printed line total without guessing missing fields. Recalculate quantity × unit price for each fully specified line. Show a table of printed total, calculated total and difference. Sum the calculated line totals separately from tax, shipping and discounts. Apply those adjustments only when the source specifies their amount or exact rule. Flag ambiguous currency and rounding. Do not assert the invoice is valid or paid. Ask me to check the arithmetic in a calculator before acting.

Copy, paste, and create. Outputs can vary by model and settings.
