"How much does it cost to build an app?" is the question we hear most. The honest answer: it depends. A simple booking app and a company-wide ERP are both called "apps", but their complexity is worlds apart. This article explains what drives the cost so you can plan your budget more accurately.
1. Number and complexity of features
This is the biggest factor. Login and user profiles are relatively simple, while scheduling, dynamic pricing, multi-level approvals or analytics reports need much more development and testing time.
2. Target platforms
Web only, mobile only, or both? For mobile, do you need Android and iOS? A cross-platform approach can lower costs because one codebase serves both platforms.
3. UI/UX design
Custom design based on user research takes more time than standard components, but it usually pays off with an app that is easier to use and causes fewer user errors.
4. Integrations with other systems
Connecting the app to payment gateways, ERP, marketplaces, WhatsApp or IoT devices adds work, especially when the other system has poor API documentation.
5. Security and scale
Apps that handle sensitive data or serve thousands of users at once need more mature architecture, security testing and infrastructure.
6. Maintenance after launch
Costs do not stop at launch. There is hosting, security updates, compatibility with new operating system versions and further feature development. Budget for it from the start.
Tips for a more efficient budget
- Start with an MVP: build the core features first, launch, then grow based on real user feedback.
- Write clear requirements: the clearer the business process you want to digitise, the more accurate the estimate.
- Prioritise: separate must-have, important and later features.
- Consider ready-made products: for common needs, a customisable product is often faster and cheaper than building from scratch.
