Why B&A Developers
Built properly, and built to last
Made for here
Local payments, prices in shillings, and apps that run well on everyday phones and weak connections.
Keeps working
Built to carry on when the internet drops, then catch up by itself.
People you can call
You talk to the founders directly, before, during and long after launch.
Yours to keep
Your data stays yours, and you can take it with you whenever you want.
Clear from day one
A written plan and quote before any work starts. No surprises at the end.
How it works
Four simple steps
From a WhatsApp message to an app your staff use every day. See the full process.
Step 1: Chat with us
WhatsApp or call. Tell us what you need.
Step 2: We plan it together
A written plan and a clear quote.
Step 3: We build, you test
Short rounds, tested on your own phone.
Step 4: Launch and support
Training for your staff, and help when you need it.
Tell us about your business
A free chat, no pressure. We will tell you honestly what would help and what it costs.
