Common questions

The setup fee covers the initial engineering, architecture design, and integration of your product. The monthly fee covers secure hosting, database maintenance, API monitoring (including Daraja status checks), and ongoing bug support.

Yes. Every tier is built on the same modular Next.js and Node.js architecture, so your codebase scales naturally as your transaction volume grows — no rebuild required.

We follow Daraja 2.0 best practices: secure backend webhooks, signature validation on every callback, and encrypted transaction payloads. API keys live only in isolated environment variables, never in client code.

Any defect in code we shipped — broken flows, failed callbacks, integration errors. New feature requests are scoped and quoted separately from maintenance.
