About Invoice Calculator

Suppliers fulfilling orders for your store typically need to invoice you for the unit value of goods after each billing period. This app lets your supplier connect with read-only order access, pull a date range, match each line item to their quotation sheet, and write a fully formatted invoice to a Google Sheet you control. The output captures order numbers, product names, SKUs, quantities, destination countries, tracking numbers, and per-order totals, ready for review and reconciliation. Your supplier pulls order data for any date range, including pre-60-day orders Read-only access — your supplier can never edit, refund, or modify orders Output goes to a Google Sheet your supplier configures and you can review Show more Show less
