Custom software development
Software built around how your business actually runs.
We design and build the systems behind growing businesses: POS and inventory, ISP billing, fleet, payroll, and the integrations that tie them to M-Pesa, your bank and your accounts.

How we work
No surprises between the first call and launch
You see working software early and often, and you always know what happens next.
- 01
Understand
We sit with the people who do the work and map how your business actually runs today.
- 02
Define
Scope, screens and a phased estimate, agreed in writing before a line of code is written.
- 03
Build
Short iterations with working demos, so you see progress and steer early.
- 04
Run
Launch, training and ongoing support as your team and processes grow.
Why Codeholix
We build what your business actually needs, and nothing it doesn’t.
01
Business first
We learn your operations before choosing any technology. The right system often does less, better.
02
Built for local realities
Mobile money, patchy connectivity, multi-branch operations and shared devices are design inputs, not afterthoughts.
03
Yours to keep
Clean, documented code and repository access throughout. No lock-in, no black boxes.

How much does custom software development cost?
It depends on scope, complexity, integrations and how many people will use the system. After a free consultation we send a written estimate broken down by phase, so you can see exactly what you are paying for.
How long does a project take?
A focused first version (MVP) typically takes 2–3 months. Larger platforms with many integrations can take 6 months or more. We agree milestones up front and demo working software regularly along the way.
Can we start small and grow the system later?
Yes, and we usually recommend it. We start with the workflow that causes the most pain, launch it, then add modules as your team adopts the system.
Can you integrate with our existing systems?
Yes, where technically possible. We integrate payment gateways including M-Pesa, CRMs, ERPs, accounting software such as QuickBooks and Xero, network equipment such as MikroTik, and custom legacy systems.
