Before committing to development, we determine whether the requirement should be solved with an existing app, an integration, Shopify configuration or a custom build.
We document the business problem, users, current workflow, systems, constraints and measurable outcome before recommending a solution.
We evaluate existing apps, Shopify-native capabilities, integration options and custom development. If an existing solution is commercially better, we say so.

We define data flows, API requirements, Shopify extensions, hosting, permissions, security controls, edge cases and release requirements.
For customer-facing and internal tools, we prototype critical workflows before committing to full production development.


The app is built in reviewable stages, with regular demonstrations and access to the delivery backlog.
We test permissions, failure states, high-volume behaviour, API limits, integrations, devices and trading-critical scenarios.
Deployment includes staging, migration, monitoring, rollback planning and trading-team support.

Post-launch support covers monitoring, incident response, Shopify API upgrades, security updates and planned feature development.

“We’ve seen +20% growth in sales, an infrastructure to track initiatives, and our highest grossing months in company history.” We took an iconic Italian fashion house into the 21st century.

A custom Shopify app is built for a specific merchant or group of stores. It can connect Shopify with other systems, automate internal workflows or add functionality that is not available through Shopify’s standard features and public apps.
Not for every custom app. Shopify Plus is required for some advanced checkout and custom Shopify Functions use cases. We assess plan compatibility during discovery before recommending an architecture.
Simple tools and integrations commonly start between £5,000 and £15,000. Customer-facing or multi-system applications typically require larger budgets. The final cost depends on workflows, integrations, security, data and maintenance requirements.
A focused integration or internal tool may take four to eight weeks. More complex customer-facing or multi-system applications can take three months or longer.
Yes. Fourmeta builds and supports integrations with ecommerce, inventory, fulfilment, customer, finance and marketing systems.
