Wholesale and B2B merchants agree rebates with their customers, then work them out in a spreadsheet. This app operates them inside Shopify. Record the signed terms as a versioned agreement, choose which companies, locations or customers it covers, and test the terms on worked examples before anything counts. Each period: calculate, review the exceptions, close, and produce a statement showing the orders behind the figure. Read-only to your store. It never moves money and never changes an order.

• Four rebate types: flat rate, retrospective tier, incremental tier, bonus
• Cover B2B companies, single locations or named customers per agreement
• See worked examples from the real engine before you approve any terms
• Statements show the tier bands, the rounding and the orders behind them
• Evidence pack ZIP with a checksum manifest for a disputed period

Your carrier bills you weeks after the sale, in a file that does not mention order numbers. So the gap between what a customer paid for shipping and what the carrier billed you stays invisible. Freight Margin Guard reads your UPS, FedEx or LTL invoice, matches every line to the order it belongs to, and shows the margin on every shipment. Extra fees, weight adjustments and lines with no matching order are listed for you to review, with the arithmetic behind each one.

• Match every carrier invoice line to the Shopify order it belongs to
• Compare shipping collected against carrier billed, order by order
• Surface surcharges and weight adjustments you did not expect
• Try a sample audit built from your own shipments before uploading a file
• Export accounting ready CSV and PDF summaries for your finance team
