Starting point

A mid-market client (several hundred employees, double-digit million revenue) wanted to automate tasks in their phone communications. The obvious option, an off-the-shelf product on the market, was too expensive and too rigid for the specific requirements. The open question: is build cheaper than buy here?

Approach

We proved the feasibility of a custom voice bot in a PoC. Fast, cost-controlled, with clear acceptance criteria. No "feels doable" gut call, but a solid basis for the investment decision.

Delivery

  • Requirements analysis for the prioritised phone tasks
  • Prototype covering the most critical voice flows
  • Cost and effort comparison build vs. buy
  • Handover into the production build

Outcome

Feasibility confirmed, economics proven. The in-house build comes out cheaper and more tailored than the off-the-shelf product. The PoC has moved into a production project at wonk.ai.
