MarginShield calculates contribution profit per order after COGS, shipping, fees, packaging, refunds, returns, RTO losses and ad spend what each sale leaves behind, not just revenue. Each order uses the COGS from its own date, stored as a snapshot, so past reports stay accurate when your figures change. Missing inputs are marked estimated with a Profit Confidence score, never guessed. Profit is broken down by product, city and courier, with a discount simulator and break-even ROAS calculator.

• Real contribution profit on every order, not just revenue minus COGS
• Past order profit stays accurate when your COGS changes later
• Flags missing expense data instead of showing a misleading profit number
• COD and RTO economics by city and courier, ranked by financial loss
• Break-even ROAS and CPA to check if ad spend is actually profitable
