Custom Apps
Purpose-built Shopify apps you own and control.
When off-the-shelf Shopify apps can't do what you need, we build apps that can. No monthly tax, no feature bloat, no compromise.

What is Custom Apps?
Every growing Shopify store eventually hits the same wall: the app you need either doesn't exist, costs more than it should, breaks at scale, or only does 80% of what you actually need. Stacking three more apps to fill the gaps just makes the problem worse.
BGS Custom Apps gets you off the app-stack treadmill. We build Shopify-native apps tailored to your exact workflow — apps you own, that don't charge per month, that do exactly what you need and nothing you don't.
Common targets: bundling, subscription edge cases, custom checkout flows, admin tooling, internal dashboards, and the kind of one-off automation that would be obvious if anyone had built it.
The deliverables.
Scoping & Technical Design
We figure out what to build before we build it. Architecture, edge cases, scaling considerations — documented.
Shopify-Native Development
Built using Shopify's app framework — Polaris for UI, App Bridge for embedding, Functions for checkout extensibility.
Checkout Extensions
Where Shopify allows it, custom checkout logic — upsells, validations, dynamic shipping rules, etc.
Theme Blocks & Sections
Custom storefront components that integrate with your theme cleanly and survive theme updates.
Admin Tooling
Internal tools for your ops team — bulk operations, custom workflows, reporting tools tailored to your business.
Documentation & Handoff
Code documented, deployment process recorded, your team can maintain it or have us do it on retainer.
The process.
Discovery & Scoping
What problem are we actually solving? What's the simplest thing that solves it? We rule out off-the-shelf options first.
Technical Design
Architecture, data model, integration points, failure modes. You see the plan before we write code.
Build & QA
Built in sprints with weekly visibility. QA across browsers, devices, and Shopify themes.
Deploy & Hand Off
Launched to your store. Documentation delivered. Your team trained on maintenance, or we keep it running on retainer.
Is this right for you?
A Strong Fit If
- Paying $500+/month for apps that don't quite fit
- Have a workflow no off-the-shelf app supports
- At scale where custom is cheaper than the app tax
- Need a competitive moat your competitors can't just install
Probably Not If
- A free or $20/mo app already does what you need
- Need it built in a week
- Don't have someone internally who can scope what success looks like
For the first time we can actually see which products and channels are profitable — not just which look busy.
