Head to head
Pro
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
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.
Supplier Trust turns every supplier invoice into an audit. Upload an invoice (Excel, CSV or PDF) and it auto-detects the columns, splits combined "set" lines into individual products, and matches each line to your real Shopify orders. It then flags overcharges, cost and shipping increases, duplicate orders billed twice, missing refunds you were owed, and commission mismatches.
- 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
- Audit any invoice layout — auto-detect columns for Excel, CSV and PDF files
- Match invoice lines to your real Shopify orders and products
- Flag overcharges, cost and shipping increases with evidence
- Catch duplicate orders, missing refunds and commission mismatches
