See every featureSuppliers 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.

- Output goes to a Google Sheet your supplier configures and you can review
- Automatic document delivery — Send invoices and receipts on your rules
- Gift receipts — Send itemized proof of purchase with prices hidden
- Templates that match your brand — Customize document layouts
