What Drives the Cost of Custom Software in Kenya?

"How much does a system cost?" is one of the first questions businesses ask, and the honest answer is that it depends on what the system must do. A simple internal booking tool and a multi-branch ERP are both "custom software", but they are very different projects. This guide explains what drives the cost so you can budget sensibly and compare quotes fairly.

Why do software quotes vary so much?

Custom software is priced mainly on effort: the time it takes skilled people to design, build, test and launch it. Two quotes for the "same" system can differ because the developers have understood the scope differently, plan different levels of quality and testing, or include different support. Comparing quotes only works when they are based on the same written scope.

What are the main cost drivers?

1. Features and complexity

Each feature takes design, development and testing. Complex business rules, such as pricing tiers, approval chains or calculations, take longer than simple data entry.

2. User roles and screens

A system with one type of user is simpler than one with customers, staff, managers and admins, each with different screens and permissions.

3. Integrations

Connecting to M-Pesa, SMS gateways, email, accounting packages, ERPs or government systems adds work, especially when the other system's documentation is limited or callbacks must be handled reliably.

4. Design and user experience

A functional internal tool needs less design work than a polished customer-facing platform used on many devices.

5. Platforms

A web application that works in the browser is usually the most economical. Adding native Android and iOS apps adds significant scope.

6. Data migration

Moving years of records from spreadsheets or an old system takes cleaning, mapping and verification.

7. Security and compliance

Handling payments, health records or personal data requires stronger security, audit logs and Data Protection Act considerations.

8. Reporting

Dashboards and exports are often underestimated. Each report needs defined data, filters and layouts.

What costs continue after launch?

Ongoing cost	Why it exists
Hosting	Servers, databases, backups and bandwidth
Maintenance	Security updates, dependency upgrades, bug fixes
Third-party fees	SMS, payment gateway charges, email services
Improvements	New features as the business evolves
Support	Helping staff and fixing issues quickly

Budget for these from the start. A system without maintenance becomes slower, less secure and harder to change.

How can you reduce the cost without cutting quality?

• Start with an MVP. Build only the must-have features first.
• Use proven building blocks for standard features such as authentication and payments.
• Choose a web app first and add mobile apps later if needed.
• Decide quickly. Slow feedback stretches timelines and cost.
• Prepare your data before migration starts.
• Write a clear brief so developers do not price in uncertainty.

How do you get an accurate quote?

Share your problem statement, users, must-have features, integrations, data to migrate and any deadlines. A professional developer may suggest a paid discovery phase for larger systems: a short, focused engagement that produces detailed requirements, designs and a fixed quote for development. It reduces risk on both sides. Our guide on planning a custom software project shows what to prepare.

Example: how scope changes the estimate

Consider two versions of a booking system for a clinic. Version A lets reception staff record appointments, see a daily calendar and send SMS reminders. Version B adds online self-booking for patients, M-Pesa deposits, doctor-specific schedules across three branches, patient records with access controls and monthly reports for management. Both are "a booking system", but Version B has several user roles, payment and SMS integrations, sensitive data and multi-branch logic. Its estimate will be several times larger, and the right approach may be to launch Version A first and grow towards B.

Should you choose the cheapest quote?

Compare what each quote includes: testing, documentation, training, ownership of the code, hosting setup, warranty period and support. A low quote that excludes these often becomes expensive when problems appear. Ask how bugs found after launch are handled and what maintenance costs.

When is custom software not worth it?

If an affordable off-the-shelf tool fits most of your process, start there. Custom software makes sense when your process is a competitive advantage, when off-the-shelf tools force costly workarounds, or when you need integrations they cannot provide. Read off-the-shelf vs custom software to decide.
