You price the product right — then guess shipping. Postage, payment fees and discounts quietly eat 8–15% of each sale, and you never see which orders lost money. MarginProof does the subtraction for you, per order, and flags the leaks.
Claim a founding spot →Your dashboard says the sale was $48. It doesn’t tell you the order actually made $4.60 — or lost money.
You set a flat shipping price months ago. Carrier rates crept up. Now half your orders under-charge postage and you eat the difference.
Payment processing, platform fees, app fees, currency conversion — each is small, together they’re a real chunk of every order you never subtract.
A code plus free shipping plus a low-margin SKU can turn a sale into an order that costs you money to fulfil. You find out at month-end, if ever.
A healthy average margin can hide dozens of losing orders. You need to see which specific orders, products and discounts drain your margin.
Automatically, per order — the full cost stack, not an average.
MarginProof pulls each order’s revenue, products, discounts and shipping charged. Nothing to export, nothing to reconcile by hand.
Enter your cost per product (or bulk import). After that it’s automatic. Start with a default margin and refine any time.
Product cost + actual shipping + payment and platform fees + discounts — the full stack, on every order. Revenue minus reality equals true profit.
Orders, products and discount codes that lost money or ran below target get flagged. One short email each week: your true margin, the 3 biggest leaks, what to fix.
Analytics shows you revenue and leaves the math to you. MarginProof does the subtraction — product cost, real shipping, fees and discounts — per order, and tells you which ones lost money. Not charts to interpret. The answer, order by order.
Honest and limited — real numbers only. You’re pre-ordering a lifetime seat.
Analytics shows revenue. MarginProof shows profit — after the shipping and fees your analytics ignores, per order, with the money-losers flagged. Different job.
A founding lifetime seat at $49 instead of $19/mo forever, and a say in what ships. It ships August 2026, with a full refund if it doesn’t. One person builds it and answers every email.
Once per product, or bulk import. After that it’s automatic. You can start with a default margin and refine as you go.
Shopify first at launch. Founding members pick which integration comes next.
Every store owner I talk to can tell me their revenue instantly — then goes quiet when I ask their profit per order. Not because they’re careless, but because nothing does the subtraction for them. So I’m building the small tool that does. Flat price, one builder, ships August. If it doesn’t ship, you get every cent back. — The person building MarginProof
