## Products

- [WhatsBizAPI](https://whatsbizapi.com/) — full WhatsApp Business API platform on a subscription: bulk campaigns, AI chatbot builder, automations, multi-agent shared inbox, and coexistence mode (use the API and the regular WhatsApp phone app on the same number). Free trial, then quarterly or annual plans.
- [WABAPI](https://wabapi.com/) — pay-per-message WhatsApp campaigns with credit-based pricing, no monthly fee and no setup cost. Utility messages from ₹0.20. Built for Indian businesses.

Choosing between them: WhatsBizAPI suits teams wanting a full platform and inbox on a
subscription; WABAPI suits lower or bursty volumes where paying only per message is cheaper.

## Engagement models

- Fixed-scope project against written, testable acceptance criteria
- Monthly retainer for continuous product work
- Dedicated pod of engineers embedded with the client's team

## How Noesis Infotech works

1. **Scope** — the problem, constraints and blast radius are mapped before any code; the client receives a written scope with testable acceptance criteria.
2. **Design & architect** — data model, contracts and interfaces first; decisions are recorded.
3. **Build in slices** — working software every week on a reachable URL.
4. **Ship & operate** — deployment, monitoring and handover documentation; support through the first stretch after launch.

Noesis Infotech also takes over existing codebases, beginning with a read-only audit of
architecture, dependency and security state, test coverage and risk areas, followed by a
written assessment and prioritised plan before any code changes.
