Private and custom apps

Private apps for your specific needs

Private apps are built exclusively for your store. When public apps do not fit your requirements or you need functionality that provides competitive advantage, private apps deliver exactly what you need without compromise or dependency on third-party vendors.

When to build a private app

Private apps make sense in several scenarios:

Unique business logic. Your business processes do not match what public apps assume. You need functionality that reflects how your business actually works.

Deep system integration. You need tight integration with internal systems—ERP, PIM, custom databases, proprietary platforms. Public apps offer generic integrations; private apps connect exactly as needed.

Competitive functionality. The functionality gives you competitive advantage. You do not want competitors using the same capabilities available through public apps.

Data control. You want complete control over how data is handled, stored and processed. No third-party services seeing your customer or order data.

Dependency reduction. Reducing reliance on third-party apps that could change pricing, features or availability. Your business-critical functionality controlled by you.

Performance requirements. You need performance optimization that third-party apps cannot provide. Direct API access and optimized code paths.

Frequently Asked Questions

Private apps are installed on a single store and do not go through the Shopify App Store. Custom apps are built specifically for one merchant but may use the custom app installation flow. Both deliver bespoke functionality for individual stores.
Private app costs vary based on complexity, integrations and ongoing requirements. Simple apps may start around £5,000-10,000, while complex apps with multiple integrations can cost £20,000-50,000+. We provide detailed quotes after discovery.
