- Cost: £3,000–£8,000
In-App Purchases & Payment Integration:
- Cost: £5,000–£15,000

- Server and Back-end Environment Needs
It can cost anything between £10,000 and £100,000 or more to create a server and back end infrastructure. back-end serverIf you consider the mobile app as an iceberg,then below the water ( unseen ) it is server and back-end infrastructure are lying down code which manages the business logic, data administration,storage etc. The app back-end includes everything that the person who uses the app can’t see but that powers the app, including the server and database, as well as all the software that is run on them and that supplies the app’s functionality.
Backend is very important for apps which have user authentication, real time database, large database to load (like e-commerce apps, social media apps, cab services).
- Development Team: Freelance, In-House or IT Staff Augmentation
The development team you decide to work with can greatly affect cost and quality.
- Freelancers: Cheaper but a gamble – there is a chance they take on too much or just disappear.
- In-House Team: Dependable but costly – as in salaries, benefits and office space.
- IT Staff Augmentation: Get expert workers without the long-term overhead.
- Developer Location: UK-Based vs Offshore Hiring
App Developers UK hiring is significantly more expensive than the offshore hiring. With offshore hiring, you can hire highly skilled workforce at one-third of the cost (without sacrificing quality).
- Integration with Third-Party Services and APIs

- Maintenance and Continued Development
Post-launch expenses are often forgotten and can add up over time. Annual operating expenses are usually 15–25% of the developed capital cost.
Cost: £3000-£15000+ per annum
Example: Revolut needs to (read: has or will be legally obligated to) spend a lot of money just to maintain their security and be compliant, often tens of thousands of dollars year after year.
