About Calpex Technologies

We build management software for the businesses that keep Kenya moving. Based in Nairobi, founded in 2024.

Who we are

Calpex Technologies is a software company based in Nairobi, Kenya. We build management systems for chamas, rental properties, retail shops, and matatu fleets. Our software helps Kenyan businesses track money, manage operations, and make better decisions.

We started because we saw too many businesses relying on notebooks, spreadsheets, and WhatsApp groups to run critical operations. These tools break down as businesses grow. They lead to lost records, disputes, and wasted time.

Our products are designed specifically for Kenya. That means M-Pesa integration, offline capability for when connectivity drops, and workflows that match how local businesses actually operate.

What we believe

Our approach to building software

Principles that guide how we work and what we build.

Local context matters

Software designed for other markets doesn't fit Kenya. We build for M-Pesa payments, intermittent connectivity, and the specific ways Kenyan businesses operate.

Practical over flashy

We focus on solving real operational problems. No feature bloat, no steep learning curves. Just tools that work for the people who use them daily.

Your data stays yours

We don't sell your data, lock you in, or charge for exports. Your business information belongs to you, and you can take it with you anytime.

Transparent pricing

No hidden fees or surprise invoices. We agree on scope and cost upfront. What we quote is what you pay.

What we build

We develop four main software products, each focused on a specific type of Kenyan business:

Calpex ChamaManager

Management software for savings groups and chamas. Track contributions, loans, merry-go-round cycles, shares, and welfare. Designed for how Kenyan chamas actually operate.

Rental Management System

Property management software for landlords and property managers. Track tenants, leases, rent payments, arrears, and maintenance requests. M-Pesa integrated.

POS System

Point of sale software for retail shops and hospitality businesses. Inventory tracking, sales reporting, and offline-capable checkout. Works even when the internet doesn't.

Matatu Management System

Fleet management software for matatu operators and SACCOs. Trip logging, revenue tracking per vehicle, and driver performance monitoring.

We also offer web development, SEO, and AI search optimisation services to help businesses establish and grow their online presence.
