Theme migration without a redesign
Changing the architecture and keeping the design is a legitimate project, and a harder sell than a redesign. It is also the one that pays back.
Tax registration thresholds, and when selling abroad gets complicated
A threshold is a date in your future, not a permission slip. The question is which of your markets has one you are about to cross, and which never had one at all.
Search relevance: synonyms, typos and the catalogue you have
Search cannot return a word you never wrote down. Most relevance projects are catalogue projects that somebody has mislabelled.
Custom checkout logic with Functions: three worked examples
Functions run inside Shopify’s own checkout, which is why they can do things no script in your theme can — and why they cannot look at a clock.
Collection merchandising rules that scale past a hundred products
Dragging tiles works until it does not, and it fails silently — the grid keeps rendering long after anyone stopped maintaining the order.
Subscription pause, skip and swap: the retention levers
Three of the four reasons people cancel are not "I want to stop buying this". Give each one its own button and most of them stop being cancellations.

Most stores asking for a warehouse want four numbers nobody agrees on. A warehouse will not settle the argument — it will just host it at higher cost.
App performance budgets: making vendors prove it

A wishlist is a retention feature that most teams buy as a conversion feature. That mismatch is why so many of them end up with a heart icon nobody measures and a dataset nobody reads.
Metafield definitions as an API contract
Half of a metafield definition can never be changed after you create it. That half is a published interface, and treating it like a settings screen is how catalogues end up with three fields that mean the same thing.
