Write down what every number in your shop means.
A metrics book gives each number you look at a written definition: what it counts, how it is calculated, who owns it and how to read it. You start from 38 e-commerce metrics we wrote, and change them to fit your shop.
It is free. Export it as Markdown, JSON, CSV or PDF, or edit it from your own Claude or ChatGPT.
38 metrics in 7 categories
Each one is written out in full, and you can read every one before you sign in. When you start your book, answer four questions about your shop and the assistant fits the template to it. Or take the template as it is.
One metric, the way your book shows it
This is Expected contribution profit from the template. In your book every line is yours to change, and the book keeps the history of every change.
- Description
What an order will earn after expected returns, costs and ads. You know it on the day the order is placed. It counts what is already sold, not sales still to come.
- When to use
Use it to see which products, orders and channels make money. It matters most where margins and return rates differ a lot between products. That is more true for clothing than for jewellery. To see sales alone, use Net sales. Recent days move a little as real carrier costs and returns replace the estimates.
- Formula
Net sales, minus Expected returns. Take off Cost of goods only for items we expect to keep, since a returned item goes back on sale. Take off what it costs to handle Expected returns, with shipping back. Then take off shipping out, payment and platform fees, and packaging. Last, take off the order's share of Marketing spend.

Take it with you
Download the book as Markdown for your wiki, JSON for a developer, CSV for a spreadsheet, or PDF for the next board meeting. Every export holds the whole book.
Connect your own Claude or ChatGPT and edit the book from there. Ask it to add a metric for your loyalty programme, and the metric is in your book.
The book holds definitions only. It never connects to your shop and never sees a sale.
