How it works

  1. 1

    Systems map

    We map every tool you use, what data each holds and where it needs to go.

  2. 2

    Integration design

    We design the sync rules and error handling and quote a fixed price.

  3. 3

    Build & test

    We build and test the integration with real data, including edge cases like refunds and duplicates.

  4. 4

    Monitor

    We monitor integrations and alert you before a failed sync becomes a problem.

Real-time rates, label automation, perishables and freight: we have built the systems that get orders out the door.

You own everything

Your code, domain, data and accounts stay in your name. No lock-in and no hostage situations.

AI that keeps you human

We use AI to take busywork off your team so they have more time for customers, never to replace the people your customers trust.

Custom Shopify Apps & Integrations FAQs

Should I build a custom app or use an existing one?

Use an existing app when one fits and is reliable. Build custom when you need your own logic, deep integration or want to avoid stacked monthly fees.

Can you connect two systems that do not have a built-in integration?

Usually, yes. If both systems have an API, webhooks or even a reliable export, we can build a dependable connection between them.

Why not just use Zapier?

Zapier is great for simple tasks. When volume grows, logic gets complex or per-task costs climb, a custom integration is often cheaper, faster and more reliable.
