Margin Intelligence OSby Structora

Your margin is lying to you.

Margin Intelligence OS connects your Shopify, 3PL, and ad accounts to show the contribution margin you actually earn — per SKU, per channel, after every cost. Because the number in your Shopify dashboard is not the number that pays your bills.

Built by Structora for DTC Shopify brands doing $1M–$10M.

The P&L says profitable. The bank account disagrees.

You think your margin is 58%. Shopify told you so. But Shopify has never seen your 3PL invoice, doesn't know your supplier raised unit costs in March, and counts a refunded order as if the outbound shipping never happened. Your real contribution margin — on your best-selling SKU — might be 31%. You've been scaling ad spend against a number that doesn't exist.

Here's how it actually plays out. A $45 candle with $12 in COGS looks like a 73% margin. Then the 3PL charges $6.80 to pick, pack, and ship it. Returns run 11% on that SKU, and each one costs you the refund, the return label, and half the product. Meta attribution says the ads are printing money, but spend per unit actually sold puts that channel underwater. None of this shows up anywhere — until you connect it.

The worst part is where the losses hide. Most brands we audit have at least one hero SKU quietly losing money on every order — usually the heavy one, the discounted one, or the one that gets returned twice as often as the rest. It sells well, so nobody looks. The winners subsidize it, the blended margin looks fine, and the cash gap grows a little every month.

The best seller loses money on every order. The winners subsidize it, and nobody looks — because the blended number looks fine.
