For HVAC, refrigeration & pest-control teams

Field work to final bill, straight from a voice note.

Your technicians already talk through every job on WhatsApp. CaseSetu listens, writes it up as a clean job record, and puts it in front of you to approve — no forms, no app to install, no chasing.

Illustrative example

Four steps. You only do one.

Technicians keep working the way they already do. The only thing that needs you is the approval.

Technician speaks

After a job, they send a WhatsApp voice note to one number. Hindi, English or Hinglish — however they talk.

CaseSetu writes it up

The note is transcribed and turned into a structured record: job type, parts used, labour hours, notes.

You approve

The summary lands on your WhatsApp with Approve and Edit buttons. Fix anything by just replying.

Invoice draft, ready

Approved jobs become invoice drafts using your own labour rate and parts prices — for you to review.

Built for how small teams actually work

Nothing for technicians to learn

No app, no login, no form. If they can send a WhatsApp voice note, they can use CaseSetu.

Understands Hinglish

Part names, brand names and mixed Hindi-English speech, the way it’s really said on site.

An end-of-day summary

One evening message with everything that was approved today — who did what, for how long.

Your dashboard, your data

Sign in with a WhatsApp code — no passwords. See every job, manage your technicians, set your rates.

Nothing reaches a customer without your yes.

Every note waits for the owner’s approval. Every invoice is a draft until you confirm it. CaseSetu prepares the paperwork — you stay in charge of it.
