The challenge
Where teams get stuck
The problems we're most often brought in to solve.
- 01
Theme cannot reflect the catalogue
The standard theme cannot present the catalogue's real complexity.
- 02
No app fits the requirement
Wholesale or subscription needs depend on workarounds and stacked apps.
- 03
App sprawl slows the store
Installed apps inject scripts that slow every page.
Overview
Shopify Plus Commerce at VulcanTech
Shopify Plus development is the customisation of Shopify's enterprise commerce plan with bespoke themes, apps and integrations. VulcanTech builds and extends Shopify themes and integrates the apps and custom logic your catalogue requires beyond the standard theme, including subscriptions, wholesale pricing and ERP synchronisation. Checkout changes are delivered within Shopify's checkout extensibility, and we are explicit about what your plan does and does not permit.

Discovery
A focused working session on your objectives, constraints and existing systems. It concludes with a scoped proposal and a clear view of value, risk and effort.

Architecture & planning
We agree the target architecture, data model and integration approach before product code is written, and secure your sign-off.
- 03
Iterative delivery
Working software reaches a staging environment on a regular cadence, giving stakeholders continuous visibility and the ability to steer priorities.
- 04
Assurance & hardening
Automated testing, accessibility and performance budgets, and a security review are completed before anything reaches production.
- 05
Launch & continuity
We manage cutover and remain engaged through an agreed support period, with a structured handover to your teams or ongoing operation by ours.
