Custom software, built for your business
When off-the-shelf doesn't fit — we build the system your business actually needs. Fixed scope, fixed price, no surprises.
CoreStack Custom Software builds bespoke business systems for Kenyan companies. We handle discovery, design, development, launch, and support — one team, one contract, one point of contact. Typical builds run 4-12 weeks depending on scope. Fixed-price quotes before any work begins.

Common questions
How long does a custom build take?+
Most projects run 4-12 weeks depending on scope. Simpler systems (CRMs, dashboards, portals) land closer to 4-6 weeks. Enterprise systems with complex integrations run 8-12 weeks.
What does a custom build cost?+
Fixed-price quotes based on scope. Projects typically start at KES 400,000 for a focused MVP and scale up from there. No hourly billing, no surprise overages.
Do you work with our existing systems?+
Yes. CoreStack Custom Software integrates with existing ERPs, CRMs, M-Pesa, banks, and third-party APIs. We build on top of your current stack — not in isolation.
What happens after launch?+
Every project includes 30 days of free post-launch support. After that, maintenance contracts are available from KES 20,000/month. You own the code either way.
