Know what every order earned.

Install Offer Suite on Shopify and it reads your recent orders: realized profit per store and per item, after every cost, each order costed as of the day it sold. Then your agents write custom offers through the API or MCP, a real cart proves each price before it goes live, and experiments are decided on realized profit.

Example: a design for the offer page, drawn with the dashboard's design system. In the dashboard today, an offer's page lists its options and cart checks, and its economics page holds the forecast and realized margins. Example: an option's margin waterfall, a chart from the dashboard's design system. Option margins are the engine's forecast for OF_DEV_KITS on the dev store's costs, captured 2 October 2026. Versions, sales and activity are specimen data.

Profit from the orders you already have.

Install the app and Offer Suite imports your store's last 60 days of orders, or a year once the store grants access to all of them, and costs each one as of the day it sold: realized profit per store and per item, net of refunds, after every cost you enter. Orders placed before your first offer count toward the store and its items; profit per offer option starts with the first order an offer sells.

The same offer holds your best and worst deal. In OF_DEV_KITS, the Ritual Set subscription keeps 32.3% of its first order and 62.0% of every renewal. Once an offer sells, each option's realized profit sits beside its forecast, net of refunds, first orders and renewals apart. Group it by ad platform, campaign or ad, and set the ad spend your agent posts beside it for realized CAC.

Costs are a ledger.

COGS with history, and every cost Shopify has no field for. Rows are appended, never edited: correct a cost today and every order it touches is repriced, while what you believed at the time stays on file. Realized profit comes in both views, current costs and as recorded.

Profit Costs Tracking

Your agents write the offer.

Custom offers, written by your agents through the API or MCP: tiers, subscribe and save, build-your-own picks, add-ons and free gifts are all one validated document. There is no offer type to choose, and a wrong document comes back with the path of every problem.

A create or replace never touches Shopify. Every replace stores draft n+1, and the live version keeps serving until a publish.

Before publishing, the simulator can price the draft against the live version, per order and per visitor, with the conversion lift it needs to break even. It is optional, and nothing it runs is stored.

Offer documents

A real cart signs off every price.

What the page shows is what checkout charges. Every visible option is checked on a real cart before it goes live, and a version that fails a check stays a draft while the live one keeps selling.

Publish and verify

Show it three ways.

Offer Suite supplies the data, the cart and a theme block that draws the buy box; it never builds your page. Whoever renders the buy box gets the same served version, the prices the API computed, and each option's cart check, and the theme block will not sell an option a real cart has not matched. A browser SDK is not available yet: your developers call the HTTP API.

Three ways to show a verified offer, from no code to your own agent
WayWho does itHow
The Verified offer theme blockIn productionThe merchant, in Shopify's theme editor. No code.App Home's setup guide opens the theme editor with the block placed on a product template. Paste the offer's id into the block's text setting and, if you like, pick an accent colour. The store's public key is written for you.
Your developersIn productionYour front-end team, in your own markup or a headless storefront.GET /offers/{id}/resolve to draw the offer, POST /offers/{id}/price for any other selection, then POST /offers/{id}/cart for a checkout URL, or GET /offers/{id}/cart-input to send the cart to Shopify yourself.
Your agentIn productionYour agent, over MCP, with your workspace's key.resolve_offer, price_offer_selection and create_offer_cart: the same three steps as the API, one tool each.

matched on a real cart, 2 October 2026

The dev store's offer, captured 2 October 2026. Every amount is one the API computed. No order is placed.

$58.60

A full paid order went through the Verified offer theme block on a Plus dev store (order #1033, $58.60). On a Basic-plan dev store the block's cart reached a checkout charging the $800.00 it showed; no order was placed there.

Dev store, 29 September 2026

After the buyer pays, one more offer can follow on Shopify's post-purchase page, added to the order in one click. Offer Suite charges exactly the option's price and books what it sold to its own offer, judged on contribution per view. It runs once the merchant picks Offer Suite for the store's post-purchase page.

Buy box Post-purchase

More buyers is not more profit.

Put the new version against the live one on the same traffic. Each visitor is assigned an arm from their own id. Pass that id to resolve and the cart, and the page, the cart and the order all carry the version they were shown. The metric is realized profit per visitor, never conversion.

A price test is one kind of experiment: the challenger charges a lower price on one-time lines, shown at checkout as the product's own price.

no change$0.10$0.42$0.26 per visitor

The interval is an always-valid confidence sequence, so reading the report hourly cannot manufacture a winner. Every arm's options are re-proved with real carts each day; an arm that stops matching pauses its experiment and everyone sees the live version again. Promoting the winner is still your call.

Experiments

Your agent does the work. You approve it.

Claude, ChatGPT or your own agent. Offers start as drafts, and nothing goes live until every visible option passes a real Shopify cart check. Over MCP, publishing also needs confirm: true and refuses without it. Over the API, the publish call itself is the approval.

Offer Suite is not open yet; brands join the waitlist. Once invited, connect any MCP client to https://mcp.offersuite.io/mcp with your workspace secret key: 78 tools in production, one per operation of https://api.offersuite.io/openapi.json.

Start with the math.

The calculators run the same margin engine as the product. The playbooks price common offers on sourced costs, the glossary defines every figure, and the comparisons say, with sources, where other tools win.

Every order, costed to the cent.

Offer Suite opens to Shopify brands a few at a time. Join the waitlist and we'll invite you when it opens to yours, or ask for a free profit audit of your past orders: realized profit per item and per offer option, and where margin leaks.
