From scope to launch — and beyond
We are an engineering team, not a marketing agency. Every engagement runs the same way: a written scope, code reviewed by a second engineer, and a price held firm once it is agreed. Here is exactly what working with us looks like.
- 01
Discovery
A scoping call to map the actual problem — current platform, the constraint you have hit, and the outcome you need. No generic pitch deck; we come with questions about your stack.
- 02
Written statement of work
Before any code, you get a written SOW: scope, milestones, acceptance criteria, and a realistic schedule. The price is fixed in writing once the scope is agreed — never an optimistic estimate that quietly slips.
- 03
Build, reviewed
Work ships as pull requests into your repository, each reviewed by a second engineer before it merges. You see progress as commits, not status-meeting summaries.
- 04
QA and launch
Every build is tested against the platform it targets — theme, Hydrogen storefront, or Shopify Plus customisation — with Core Web Vitals and checkout flows verified before go-live.
- 05
Optional retainer
Most clients stay on an engineering retainer afterwards. The relationship compounds because we keep the context about your codebase instead of rebuilding it every time.
What every engagement includes
- →A written statement of work with milestones and acceptance criteria
- →Code shipped as pull requests, reviewed by a second engineer
- →Documentation and a handover walkthrough with the engineer who built it
- →Core Web Vitals and checkout verified before launch
- →A fixed price, held firm in writing once scope is agreed
Ways to engage us
Fixed-scope project
Well-defined work with a clear finish line — 8–16 weeks is typical for a Shopify Plus build. One SOW, one price, milestone-based delivery.
Engineering retainer
Ongoing development, performance work, app updates, and new features against a monthly engineering allocation. Best when the roadmap keeps moving.
Hybrid programme
A fixed-scope build to launch the core, then a retainer to iterate. Phased delivery for larger replatform or migration programmes.
Scoped service pages
Most engagements start from one of these. Each page covers the deliverables, timeline, and how we price the work.
Why Work With Us?
We're not the cheapest option, but we do things properly. Here's what that means.
Code You Can Maintain
We write code that your next developer can actually understand. Properly documented, sensibly structured.
Fast Stores
Every site we build scores well on Core Web Vitals. Slow stores lose sales—we make sure yours doesn't.
Secure & Compliant
GDPR-ready implementations with proper data handling. No cutting corners on security.
Ongoing Support
We offer retainer packages for clients who need regular updates and maintenance.
How we scope a platform engagement
Most engagements start with a platform decision before any code is written. If you are weighing where to build or replatform, our engineering comparisons lay out the trade-offs the way we assess them internally: Shopify Plus vs BigCommerce Enterprise, Shopify Plus vs Adobe Commerce, and Shopify Plus vs NetSuite SuiteCommerce.
When the decision is a migration, the engineering risk sits in data mapping and redirect strategy, not the build itself. We cover the full process in our platform migration checklist and a worked example in the Volusion to BigCommerce migration guide. Ready to scope one? Request a migration assessment.
