See every featureProfit Guard calculates true net profit on every Shopify order the moment it arrives. Configure your payment processing rate, shipping rate, and COGS ratio once. Profit Guard handles the rest. Orders below your profit threshold are automatically flagged and tagged in your Shopify admin so you can act immediately. The standard tier uses COGS ratio estimation.
Partial returns on discounted orders often over-refund because discount allocations are not applied correctly. RefundMath calculates the exact refund from those allocations for selected items and quantities, including tax credit. Paste an order ID or URL, select return items, copy the correct amount, then finish the refund in Shopify. Example: $500 order with a $50 discount.
