Frequently asked questions

How much does it cost to build a web or mobile app in Kenya?

Tech Deciphers works on a fixed price quoted in Kenyan Shillings after a short discovery call. Small websites and integrations typically start around KES 30,000–150,000; full web or mobile applications and SaaS platforms range from KES 300,000 upwards depending on scope. You get the full scope and price in writing before any payment, with a 50% deposit to start and 50% on delivery.

Do you integrate M-Pesa (STK Push and Daraja API)?

Yes. M-Pesa integration is a core service. We implement STK Push, C2B paybill/till callbacks, and B2C disbursements on Safaricom's Daraja API, including callback verification, idempotent request handling, and a reconciliation job so no payment is ever silently lost.

Can you make my POS or ERP KRA eTIMS compliant?

Yes. We build a KRA eTIMS integration layer that generates a compliant tax invoice for every qualifying sale, submits it to KRA in real time, stores the acknowledgement number and QR code, and queues submissions with automatic retry when a branch is offline.

How long does a project take?

Most integrations ship in 2–4 weeks. A typical web or mobile application takes 6–12 weeks depending on scope. Every proposal includes a realistic timeline with sprint milestones and working-software reviews.

Where is Tech Deciphers based and who do you work with?

Tech Deciphers is based in Nairobi, Kenya and works with businesses across Kenya and East Africa — fintech and payments companies, logistics and transport operators, government bodies and NGOs, and SMEs and enterprises.

Do you provide support after launch?

Yes. We offer maintenance and support on retainer — bug fixes with an SLA, security patches, feature additions, and 24/7 uptime monitoring. We do not disappear after go-live.
