"How much does it cost to build a custom app in Kenya?" is the first question every client asks us — and it is the right question to ask. The honest answer: it depends on what you are building, who builds it, and how you scope the first version. This guide walks through what actually drives the price.
What drives the price
Custom software is priced by the work, not by the hour count alone. Four things move the number:
- Scope. A single-user internal tool is a different project from a customer-facing platform with payments and field apps. The fastest way to control cost is to control scope.
- Platforms. A web application, a mobile app, or both. Mobile adds the cost of field-friendly design, offline handling, and app store distribution.
- Integrations. Payments (M-Pesa paybill or till), SMS, ERP, and accounting systems all add integration work — and they are usually non-negotiable for real businesses.
- Team and timeline. A focused senior team moving in short cycles costs more per month and delivers sooner. There is no cheap and fast.
What projects cost in Kenya
Nobody honest will quote you a fixed number before understanding your scope. But after more than a decade of building software in Nairobi — and comparing notes with other agencies in the market — the same planning bands keep coming up. Use them to sanity-check any quote you receive:
One to three weeks. You get requirements, wireframes, a technical approach, and a fixed build quote. Worth doing even if you end up not building immediately.
Six to ten weeks. A single workflow done properly: a dashboard, a booking system, an inventory or reporting tool for one team. No complex integrations.
Three to six months. This is where most real businesses land: a web platform plus mobile field apps, M-Pesa paybill/till integration, SMS notifications, and an admin back office.
Six months and beyond. Billing engines serving thousands of accounts, third-party ERP and accounting integrations, audit trails, and compliance work push cost and timeline up together.
Treat these as planning bands for agency-built software in the Kenyan market, not quotes. A solo freelance developer can come in below these ranges for small projects — with the trade-offs around reliability and continuity described in how to choose a development partner. Large firms and offshore teams often quote above them. Support and evolution after launch typically run 10–20% of the build cost per year.
Every project is quoted individually after discovery, and we will give you a clear estimate even if that does not end up being us building it. Tell us what you are building and we will reply with next steps, or read about how we structure pricing and engagement.
How to keep your first version affordable
The most expensive mistake in custom software is building too much, too early. A well-scoped first version, the smallest product that solves the core problem, gets you to market faster, cheaper, and with something real to react to. Features you thought you needed often turn out to be unnecessary once users are on the system.
It also helps to separate what you must own from what you can rent. Infrastructure, SMS, and payment rails are cheaper to buy than to build. Your budget should go into the workflow that makes your business different.
What you get for the money
Unlike subscription software, custom development leaves you with an asset you own. No per-user fees, no forced upgrades, no features you pay for and never use. Over several years, owned software routinely works out cheaper than stacking subscriptions, something we cover in detail in why invest in custom software.
Frequently asked questions
How much does a simple app cost in Kenya?
A focused web or mobile app that solves one workflow — what most people mean by "simple" — typically falls in the KES 500,000 to 1,500,000 range from a Kenyan agency, and takes six to ten weeks. If a quote comes in far below that, ask what has been left out: discovery, testing, deployment, and post-launch support are usually where cheap quotes cut corners.
Why won't agencies just give me a price upfront?
Because scope is the price. Two "ordering apps" can differ by ten times in cost depending on whether they need payments, field apps, and reporting. Serious agencies run a short paid discovery (see the sprint band above) and return a fixed quote — that discovery fee is usually credited against the build if you proceed.
How long does custom software take to build?
Six to ten weeks for a well-scoped first version; three to six months for a customer-facing platform with payments and mobile apps. Timelines stretch when scope grows mid-project, which is another reason to keep the first version small.
What happens to costs after launch?
Budget roughly 10–20% of the build cost per year for hosting, support, and small improvements. The subscription trap — per-user fees that grow with your business — is exactly what custom software avoids, as we explain in why invest in custom software.
