Case studies, with the real numbers.
Real jobs, with the real numbers. Each one says what went wrong in the shop, what I did, and what changed. If a job did not pay for itself, you will read that here too.
the same job, removed
How BoxQuiz stopped paying two apps for a job Shopify already did.
A Danish puzzle shop paid for two AdNabu apps to tell Google about its sales. Shopify's own Google & YouTube channel already does that job. Running both meant some sales could be counted twice. I checked every piece of the shop's tracking: the code that tells Google and Meta when someone buys. I moved the shop onto Google's new tag. I switched on the Merchant Center and Customer Match settings that were off. Then I removed both apps, but only after two weeks of live numbers showed the Shopify channel had it covered.
counts, all put right
One system I built to do three jobs Shopify could not do for a shop that sells to businesses.
A shop that sells to businesses and to everyday shoppers moved to Shopify in late 2025. Its products moved over fine. But three jobs it relied on had no home in Shopify. Bundle stock counts had stopped updating. The team sorted trade orders by hand. And its customer groups sat in another system Shopify could not see. I built one system that does all three jobs. It runs on an account the shop owns, so the shop keeps it whatever happens.
across 7 open supplier orders
True stock counts and arrival dates for all 2,238 of Fathom's product variants.
Fathom sells cookware and tableware from three stock locations. Its bundle pages said "ships in X days" instead of a real date. And the stock maths missed bundles whose parts sat in different locations. I wrote two small apps. They put the real stock at each location, and the real arrival date, on the shop's pages. A full test run on the live shop checked 74 of 74 stock items across 7 open supplier orders. Zero errors.
