# Offer Suite > An offer engine for Shopify brands, run by their agents through an API. Offers are validated documents bound to Shopify; nothing goes live until a real Storefront cart charges what the offer promises; verified offers are served to a buy box through a theme block or the API; realized profit is tracked per offer option, net of refunds, renewals apart and cancelled orders counted separately, each order costed at the costs in effect on its date, in a current and an as-recorded view. The calculators on this site run the same margin engine as the product. Offer Suite is not open yet; brands join a waitlist: [Join the waitlist](https://offersuite.io/waitlist) ## For agents - OpenAPI 3.1 description of the API: https://api.offersuite.io/openapi.json - MCP server: https://mcp.offersuite.io/mcp (send the workspace secret key on each request; it is never stored) - How agents use Offer Suite: https://offersuite.io/features/agents ## Site - [Know what every offer earned](https://offersuite.io/): Offer Suite builds Shopify offers from documents your agents write, proves each with a real cart, and reports realized profit per option with costs as of the sale. - [Join the waitlist](https://offersuite.io/waitlist): Offer Suite opens to Shopify brands a few at a time.

[Contribution margin: definition and formula](https://offersuite.io/glossary/contribution-margin): What an order keeps after every cost that grows with it: product cost, fulfilment, shipping, card fees and refunds. The number an offer should be judged on. - [Gross margin: definition, formula and example](https://offersuite.io/glossary/gross-margin): Revenue minus the cost of the goods sold, as a share of revenue. The accounting margin: it leaves out shipping, fulfilment and payment costs. - [Profit per visitor: definition, formula and example](https://offersuite.io/glossary/profit-per-visitor): The profit an offer earns for every visitor who sees it: margin per order times conversion rate. It weighs a lower price against more buyers fairly. - [Break-even conversion lift: definition and formula](https://offersuite.io/glossary/break-even-conversion-lift): How much more an offer has to convert to earn, per visitor, what another offer earns: the gap a cheaper offer, a gift or a discount must close. - [Average order value (AOV): definition and formula](https://offersuite.io/glossary/average-order-value): Total order revenue divided by the number of orders. Useful for spotting a trend, misleading for setting thresholds because it hides the shape of your orders. - [Cost of goods sold (COGS): definition and formula](https://offersuite.io/glossary/cost-of-goods-sold): What the units you sold cost you to make or buy. In an offer calculation it is charged per unit, gifts included, at the cost in effect on the order's date. - [Landed cost: definition, formula and example](https://offersuite.io/glossary/landed-cost): A unit's full cost on your shelf: the supplier's price plus inbound freight, duties and brokerage. The unit cost an offer should be priced on. - [Fulfilment cost: definition, formula and example](https://offersuite.io/glossary/fulfilment-cost): What it costs to get an order out: pick and pack, extra picks, the box and the label. Charged per order or parcel, which is why bundles and gifts change it. - [Refund reserve: definition, formula and example](https://offersuite.io/glossary/refund-reserve): A share of revenue set aside, in a forecast, for the refunds that will come. It turns an unknown future cost into a rate you can price an offer against. - [Refunded revenue: definition, formula and example](https://offersuite.io/glossary/refunded-revenue): The part of an order's revenue given back, counted after discounts and before tax, and never taken off the order's cost, because the goods already shipped. - [Realized profit: definition, formula and example](https://offersuite.io/glossary/realized-profit): The profit orders actually made: revenue net of refunds, minus the cost of every unit shipped, per offer and per option, first orders and renewals apart. - [Cost restatement: definition, formula and example](https://offersuite.io/glossary/cost-restatement): Repricing past orders after a cost is corrected or backdated, while keeping what they were booked with. Both numbers stay, so the change is traceable. - [Renewal order: definition, formula and example](https://offersuite.io/glossary/renewal-order): A subscription order the subscriber didn't place by hand, billed by the subscription contract. Priced at the renewal price, without first-order-only costs. - [Subscribe and save: definition, formula and example](https://offersuite.io/glossary/subscribe-and-save): A standing discount for buying on subscription, often with a deeper first-order discount. Its cost has to be priced over the renewals, not the first order. - [Retention rate: definition, formula and example](https://offersuite.io/glossary/retention-rate): Of subscribers who received an order, the share who receive the next one. Each renewal's profit is weighted by it, so small changes compound quickly. - [Cancelled order: definition, formula and example](https://offersuite.io/glossary/cancelled-order): An order cancelled after it was placed. It is not a sale: no revenue, refund, cost or profit should count for it, whether or not money was refunded. - [Free-shipping threshold: definition and formula](https://offersuite.io/glossary/free-shipping-threshold): The order value above which shipping is free. It costs the shipping revenue of every order already above it, and pays only if enough smaller orders top up. - [Conversion rate: definition, formula and example](https://offersuite.io/glossary/conversion-rate): The share of visitors who buy. An offer test's most reported number and its least sufficient: a better-converting offer can earn less. - [Gross revenue: definition, formula and example](https://offersuite.io/glossary/gross-revenue): An order's revenue as Offer Suite books it: line prices after discounts plus shipping charged, tax excluded, frozen at the sale as placed. ## Compare - [Intelligems alternative: Offer Suite compared](https://offersuite.io/compare/intelligems): Offer Suite and Intelligems side by side: what each does, pricing, what it measures, and where Intelligems wins.
