Verdict

Who should choose what

Callin.io (ai voice platform) vs Markate (field service platform): pick the model that matches how you want calls handled.

  • Choose Callin.io if you want highly customizable AI voice for inbound and outbound calling.
  • Choose Markate if you need field service ops (jobs, dispatch, technicians) as the system of record.
  • Consider ServiceAgent if you want an AI front office that answers 24/7, books the job, and takes payment without forcing a per-minute receptionist model.

One of these is ours. Here is the honest pitch.

ServiceAgent is the AI front office built for home service teams. It answers every call, books the job, and keeps your records straight. Try it and judge for yourself.
