ReceiptsMRR reads your Shopify order totals via read-only OAuth and computes your trailing 30-day net revenue — paid orders minus refunds. The figure displays on a public profile that refreshes hourly with a tamper-evident sync timestamp. We never access customers, products, settings, or any field outside order totals. Merchants use it to back revenue claims with verifiable receipts when selling a store, partnering with a brand, or launching a course. We provide a middleman of trust.
