How a project should run
- Discovery: goals, users, constraints and the current setup.
- Scope: a written list of what will and will not be built.
- Build in staging: on a duplicate theme, never on the live store.
- Testing: on real phones and major browsers, including checkout.
- Launch: a plan to roll back if something breaks.
- Handover: documentation and code ownership.
How to choose a provider
- Ask for real Shopify projects and results. See my case studies.
- Check they use staging and version control.
- Ask how they protect speed and Core Web Vitals.
- Ask who does the work.
- Check support after launch.
Custom code or an app?
Use a theme setting if one exists. Use an app if it is light and reliable. Use custom code when the feature is core to your business or apps add too much weight or cost.
