Custom features and connections your store is missing.

When no app does quite what you need, or you're paying for five that half work, we build the feature properly and connect Shopify to the systems you already use.

What we build

From one missing feature to a fully connected store.

Private apps for your store

Features no public app offers, built for your store only and managed from your Shopify admin.

Stock, ERP and accounting links

Stock levels, orders and payouts kept in step automatically, so nobody retypes anything.

Shipping and fulfilment

Orders sent to your warehouse or 3PL, with tracking numbers sent back to the customer.

Product builders and options

Personalisation, made-to-order options and price rules your theme can't handle alone.

Automations

Order tagging, scheduled imports and reports that run by themselves.

App clean-up

Remove apps you no longer use, replace several with one, and clear the code they leave behind.

Connected

Shopify at the centre, everything else in step.

How it works

We check whether you need to build at all.

  1. Tell us what should happen

    Describe the job in plain words: what goes in, what comes out, and who uses it.

  2. We check existing apps first

    If an app already does it well, we'll tell you and save you the build.

  3. Fixed scope and quote

    What the app will and won't do, the price and the timeline, in writing.

  4. Build, test and launch

    Tested with sample orders on a development store first, then launched and watched.

Questions

Before you get in touch.

Something else? Email hello@thecodewhiz.com.

Is it a public app anyone can install?
No. We build custom apps for your store only, so there's no shared listing and no monthly fee to us.
Will there be running costs?
Some apps need a small server to run. If yours does, the quote says so and what it costs, and the account is in your name.
What if Shopify changes its systems?
We build on Shopify's supported APIs. A care plan covers keeping your app working when they change.
Can you fix an app someone else built?
Usually, yes. We review the code first and tell you whether to fix it or rebuild it.
