Every promo as one contribution-margin line, with a verdict.Every discount read in profit, not revenue.
Margin OS is a promo ledger in true contribution margin: each code, automatic and manual discount as a single line showing what you gave away versus the realized CM1 the promoted orders produced, with a Healthy, Margin-thin or Underwater verdict on every one. The give is split by mechanic into product give and shipping subsidy, scored on incrementality, and run through a restructure simulator. Then it hands you who to wean onto full price and who to suppress. We tell you the move; we do not run your store.

The questions behind every promo decision.
Not "how much revenue did the sale do." What it cost in margin, who it actually won, and who to stop subsidising.
Which lever earns its keep, and is the lift real?
A promo verdict tells you about one code; the mechanic tells you about the lever. Margin OS scores each discount mechanic on realized-CM1 efficiency, then asks the harder question: does it cannibalise full-price sales, just pull orders forward, or drive genuinely incremental volume? Incrementality is measured against a holdout, so you keep the lever that wins net-new orders and retire the one that discounts demand you already had.
- Give per $1 CM1. Every lever ranked on the discount it hands out per dollar of realized margin
- Cannibalization & pull-forward. Give flowing to full-price buyers and orders that came early
- Measured incrementality. The causal lift each mechanic drives, read against a holdout
Tune the promo before a dollar leaves the door.
Before you run a promo, see what it gives away and who it targets, in true CM1. Configure depth, eligibility by dependency band and audience reach, and the give, the audience and the net contribution recompute live in a CM1 cascade. A portfolio restructure re-depths every band at once, so you can hold the full-price loyals out of the next sitewide sale and watch the blended discount rate and the margin recovered move together.
- Single-promo designer. Depth, eligibility and reach, with the give and audience live
- CM1 cascade. Baseline margin, the give, the incremental lift and the net, end to end
- Portfolio restructure. Re-depth each dependency band and read the margin recovered
Know who to wean, and who you're just subsidising.
Stopping discounts blind loses customers; discounting blind burns margin. Margin OS scores every customer on full-price propensity and sorts the whole base into dependency bands, from full-price loyal to discount-only, in true CM1. Then it turns the edges into two exportable audiences: the full-price-loyal buyers you are needlessly subsidising, and the valuable discount-dependent ones worth weaning onto full price.
- Dependency bands. The whole base scored on full-price propensity
- Subsidy leak surfaced. Loyal customers being discounted for no reason
- Suppress & Wean audiences. The two lists this engine produces, exported to your email tool
Built on your store, reconciled to true profit.
Discounting is read straight off your orders and costs. No ad connection is required to see the margin cost of a promo.
◷Orders & discounts
Every order, refund and discount from your store, so the discount given is net and real and tied to the customer who used it.
☵True cost
COGS, landed cost, shipping and payment fees, so the discount is measured against the margin it actually erodes, not the headline price.
↗Audiences & holdouts
The suppress and wean audiences sync to your email tool, and the same connector runs the holdout that measures whether a mechanic drove genuinely incremental margin. The discounting decision becomes a send your team controls.
