The Store Desk

Know what an order earns before you spend to win it

six skills·one subagent·one command·9-page guide

Your agent builds the contribution per order with every line of arithmetic shown, reads payback from the cohorts you actually have, and prices a promotion before it runs.

Executive summary

The problem
Revenue is the one figure that improves when you discount, pay more to acquire, or a third of an order comes back. A store can double its top line and run short of cash in the same quarter, and the dashboard never shows which orders lost money.
What it does
Six skills and a read-only catalogue-reader check your exports first, then walk each order down the Contribution Ladder with the arithmetic shown, read payback from real cohorts, compare channel margins and price each promotion before it runs.
Why take it
Every spending decision rests on what an order leaves behind. This gives you that number per SKU and per channel, so you stop buying orders that cost more than they earn.

For store owners and ecommerce managers running on revenue who need to know what an order leaves behind.

In the first week you will

  • 01Run unit-economics-sheet on your best seller and read the Contribution Ladder down to what the order actually leaves behind
  • 02Run /pdp on a product page and get the Objection Ledger, every buyer question marked answered, buried or absent
  • 03Price the quarter with promo-planner and see the break-even volume of each promotion before anything is discounted

Contents of the Kit

  • 01Six installable agent skills: unit-economics-sheet, cohort-read, channel-economics, product-page-audit, promo-planner, returns-review
  • 02The catalogue-reader subagent: reads a product, order or returns export and reports what each column holds, what is missing and what is inconsistent, before any arithmetic runs. Read-only
  • 03A /pdp slash command that opens a product page audit from a URL or a pasted page
  • 04The Contribution Ladder as a worksheet: seven rungs from list price to what the order actually leaves behind, with every line of arithmetic shown and every assumption labelled
  • 05Blank templates for the unit economics sheet, the cohort table and the returns log
  • 06A 9-page Field Guide on running a store on contribution rather than revenue, and plugin manifest included

One skill, as it ships

SKILL.md

unit-economics-sheet

Use when
Use when a store owner asks what an order actually earns, what they can afford to pay for a customer, whether a SKU is worth stocking, or why revenue is growing and cash is not. Never invents a cost, a fee or a margin.
Requires
The SKU, order or basket, and the channel it sold on · List price excluding VAT · Landed cost of goods · Channel fees
Will not
Never invent a cost of goods, a fee, a shipping tariff, a return rate or a benchmark · Never merge a platform's reported figures with the store's own · No promised improvement
Returns
Contribution Ladder: {SKU} · {channel} · {period}

One of six skills in the kit · All of them install the same way

The contents, in full · six skills, one subagent, one command
  1. 01unit-economics-sheetOne SKU, one order or one basket down the Contribution Ladder: list price, discount, net revenue, cost of goods, fulfilment, shipping and packaging, payment fees, channel fees, returns provision, variable acquisition, contribution. Every rung shows its arithmetic on its own line, any figure you do not supply is asked for or written into an assumptions block, and the sheet states which rungs are estimates so the total is never read as accounting.
  2. 02cohort-readOrders or customers grouped by first-purchase month, with repeat rate, orders per customer and cumulative contribution per cohort, then the payback month wherever the data actually shows it. It refuses to project: lifetime value is reported as observed-to-date value with the observation window named beside it.
  3. 03channel-economicsYour own store against a marketplace, a wholesale account or a third channel, per unit, after the fee schedule you supply: referral or commission, fulfilment, storage, returns handling, and the advertising it now takes to be visible on a surface that sells its own shelf. It names which channel buys you a customer and which merely rents you an order, and refuses to compare channels whose fee schedules you have not supplied.
  4. 04product-page-auditA product page or a marketplace listing as an Objection Ledger: every question a buyer would need answered before paying, each marked answered, half answered on the page, buried below the fold, or absent. Findings cite the element on the page, are ranked by the objection's weight rather than by ease of fixing, and carry no promised uplift, because nobody can promise one.
  5. 05promo-plannerA promotional calendar built against a discount policy you supply, with the margin cost of every planned promotion computed on the ladder before it runs: the contribution given away per unit, the volume the promotion has to add to break even, and how much of the discount is going to buyers who would have paid full price. It applies a policy, it does not write one.
  6. 06returns-reviewYour returns export read by SKU, by reason and by channel: the return rate, the contribution each return consumes (twice, since the order also paid to be won), the SKUs that carry the problem, and the cause routed back to where it belongs, usually the page, the size guide, the photography or the packaging. Legal and tax questions about refunds are written out as questions for a qualified adviser, never answered.
  7. 07catalogue-reader (subagent)Reads a product export, an order export or a returns file and reports what is in it: the columns, the grain, the coverage, which SKUs lack a cost, which orders lack a channel, which fields are inconsistent between rows. It fills no gap with a guess and runs no arithmetic, so the sheet is never built on a column nobody checked.
  8. 08/pdpThe slash command that opens a product page audit from a URL or a pasted page.

Think Like a CMO calls marketing return on investment a broken speedometer. Ecommerce has its own, and it is revenue. The honest number is contribution per order: what is left after the goods, the fulfilment, the fees, the discount and the orders that come back. The Store Desk builds that number and shows its arithmetic. It invents no conversion rate, margin, fee or benchmark: every number is yours, or it is labelled an assumption.

Pairs with

The Ecommerce Operator is the manual this kit is built from: the Contribution Ladder, the Payback Floor, the Channel Rent and the Objection Ledger are its frameworks, and Part VI documents every tool here. Think Like a CMO explains why the gauge on the dashboard decides the behaviour of the business, and why pricing is a brand decision before it is a margin lever. The Third Wave of Digital Marketing explains the surface your marketplace listing now competes on, since the retailer selling you shelf space is also selling advertising against it. The Analytics Desk decides what gets measured before it is built; this kit assumes the numbers exist and asks what they leave behind.

Before you buy

01Do I need Claude Code?

No. Every skill uploads to claude.ai as a zip. Subagents and slash commands are the Claude Code extras.

02I am not a programmer.

Install is copying folders into a .claude directory. The Field Guide in each kit assumes nothing beyond that.

03Will it work in my agent?

Skills follow the open Agent Skills standard (SKILL.md), so any agent that reads it can run them. Built for Claude first, our recommended agent.

04Do the tools invent numbers?

Never. Every figure is supplied by you, confirmed by you, or labeled as an assumption in the output.

05How does it arrive?

Instantly. Pay by card and the download link is in your inbox within seconds, and on the confirmation screen.

06Is this a subscription?

No. One payment, lifetime access to your download, every future revision of what you bought included.

07What if it is not useful to me?
