MVP stands for Minimum Viable Product. It is the first working version of an app, containing the essential features needed to solve the main problem and allow the idea to be tested with real users.

Starting with an MVP helps reduce the initial development cost and avoids spending money on features that may not yet be needed. Once the app has been tested and the business has received user feedback, further features, integrations and improvements can be added in planned development phases.

A fully working, fixed-scope first version of your app, ready for testing with real users or presenting to stakeholders. Depending on the agreed requirements, this may include the user interface, secure data storage, user accounts, essential third-party integrations and testing across the agreed platforms. Source-code ownership and intellectual-property arrangements are confirmed in writing before development begins.

Yes. An MVP is designed to provide a focused first version that can be expanded as the product grows. Additional features, integrations, platforms or design changes can be planned as a separate development phase, with the scope, timescale and price agreed before work begins.rojects.

Yes. We can integrate artificial intelligence into an app to support features such as document analysis, content generation, image recognition, automated recommendations, intelligent search and conversational assistance.

AI features normally rely on specialist third-party services, which may charge according to usage. We will explain the likely costs before development and can design suitable usage limits, subscriptions or credit packages to help keep the app commercially sustainable.

Not always. Some simple apps can store data securely on the user’s device and may have little or no ongoing hosting cost. Apps with user accounts, shared data, payments, AI features or live content will usually require a secure database and backend hosting.

We will recommend only the infrastructure your app genuinely needs and explain all expected running costs before development begins. Wherever practical, these services will be created within your business’s own accounts so you retain ownership and control.

Depending on the features included, your app may have ongoing costs for services such as hosting, databases, AI usage, payment processing, developer accounts and third-party integrations.

We will clearly explain the expected running costs before development begins. There is no compulsory monthly support contract, although optional maintenance and support packages are available if you would like us to manage updates, monitoring and future improvements.

Some app features, such as artificial intelligence, mapping, messaging or document processing, may incur charges each time they are used. We can build suitable subscriptions, credit packages or fair-usage limits into your app so these costs are covered by the income it generates.

Before development begins, we will explain the likely charges and recommend a pricing structure designed to protect your margins, prevent unexpected costs and keep the app commercially sustainable as its user base grows.

Once all agreed invoices have been paid, you will own the bespoke app, source code and intellectual property created specifically for your project, in accordance with the development agreement.

Third-party software, open-source components and external services will remain subject to their own licence terms. We will provide the project files and relevant access details so your business remains in control and is not permanently tied to Bullion Apps for future development.

 Yes. Unless your proposal states otherwise, we build your app for both Apple iOS and Android using a shared cross-platform codebase. This provides a consistent experience across both platforms while keeping development and future maintenance more efficient.

Any platform-specific features or additional versions requiring separate development will be identified and explained before work begins, so there are no unexpected charges.

No. We develop software for a wide range of commercial, industrial and specialist markets—not only consumer apps listed publicly on the Apple App Store or Google Play.

This includes private construction and business applications for inspections, RAMS, COSHH, asset management, reporting, digital forms, photographic evidence, offline site work and other operational processes. Apps can be provided through secure web portals, private organisational distribution, company-managed devices or dedicated Windows, iOS, Android and web platforms.

We will recommend the most suitable technology and distribution method for your organisation, whether the finished product is a public app, an internal company system, a desktop application or a secure browser-based platform.
