Sample data, real code. Nine marketplaces and three storefronts, settled into one base currency.

Every client gets their own. We are not reselling a product.

This one was built for a multi-channel seller, so it counts marketplace commissions and cross-border shipping. A single-storefront Shopify brand does not need those columns and gets different ones — subscription churn, discount depth, cost per acquisition against contribution.

The build starts from your questions and your cost model, not from a template. That is the whole difference between an agency and an app: an app has to average you out, we do not.

02 — The work

What we build.

The storefront

Themes and layout: product pages, collections, the cart
Apps connected to the store, or written where none fits
Checkout: payment methods and delivery rates
Page speed, measured before and after each change
Google product feeds and Merchant Center
Imports and exports of products, customers and orders

Panels that show real profit

One view across every store and marketplace
Landed cost per batch, with freight and duty included
Assortment ranked by contribution, not by revenue
An alert when return on ad spend falls below break-even

Automating the manual hours

Listing pipelines instead of four cards an hour
Supplier and carrier invoices reconciled against what was agreed
Stock and order sync between shop, warehouse and accounts
Scheduled exports into your own data warehouse

AI where someone is still doing it by hand

Product copy and imagery at catalogue scale
Support triage — “where is my order” is usually the biggest single ticket category
Pre-publication checks on cards and claims
Review and ticket text turned into a weekly read

The joins between systems

Shopify ↔ warehouse ↔ accounting
Server-side events into the ad platforms
Marketplace feeds that survive a tariff change
Migrations that keep the order history intact

03 — The difference

A marketing agency configures other people's tools. We write the tool.

They configure someone else's software.

We write our own, for your cost model.

They send a report.

We hand over a working system.

They keep you on a monthly retainer.

We hand over the code and the keys.

04 — Terms

How we work.

Least privilege

Read-only reporting scopes to begin with. We ask for write access one scope at a time, and tell you what each is for.

Everything in your name

Repositories, hosting, API keys and ad accounts are created under your organisation. We are a collaborator, not the owner.

A month at a time

Cancel with a fortnight's notice; we finish the month's work before we stop.

Whoever quotes it, builds it

No account manager between you and the person writing the code.

05 — Prices

What things cost.
