Guide to hiring a Shopify agency

Shopify powers over 1.7 million stores worldwide — and for good reason. But getting the most from Shopify, especially at scale, requires specialist expertise. Shopify agencies help brands build faster, sell more, and operate more efficiently on the platform.

What is Shopify?

Shopify specialists design and build custom storefronts, develop custom Shopify apps, implement Shopify Plus features (checkout extensibility, B2B functionality, multi-currency, markets), integrate third-party apps and custom middleware, and optimise existing Shopify stores for performance and conversion. Some agencies also specialise in Shopify migrations from other platforms.

When should you hire a Shopify agency?

Engage a Shopify agency when your existing theme is limiting design aspirations or performance, when Shopify Plus features would unlock significant operational or revenue improvements, when third-party app integrations are becoming unmanageable or conflicting, or when you're migrating from another platform and need a safe, data-accurate transition.

What to look for in a Shopify agency

Shopify Plus partner status — official partner agencies have access to deeper support resources
Liquid, React, and Shopify App development experience
Track record with stores of similar size and complexity to yours
Theme architecture knowledge — Shopify 2.0 sections and blocks expertise
Klaviyo, ReCharge, Gorgias integration experience if these are in your stack

How much does Shopify cost?

Shopify theme builds range from £8,000–£30,000 for a fully custom theme. Shopify Plus implementations with custom checkout and B2B features run £25,000–£80,000. App development costs £15,000–£60,000+ depending on functionality. Ongoing Shopify support retainers run £1,000–£4,000/month.

Frequently asked questions about Shopify agencies

Do I need Shopify Plus?

Shopify Plus (from ~£1,700/month) is typically worth it above £1M annual revenue. It unlocks custom checkout scripts (being replaced by checkout extensibility), unlimited staff accounts, wholesale/B2B channels, dedicated support, and significantly better API rate limits.

Should I use a Shopify theme or build custom?

Premium themes like Prestige, Impulse, and Turbo cover the majority of Shopify stores well and cost £200–£400. Custom themes are worth the investment when your brand requires significant visual differentiation, complex product merchandising, or performance optimisations beyond what themes support.
