The setup
Owner Ray fans bookings@ out to the office plus four plumbers. Each plumber reads their own inbox on their phone between jobs.
How the mail flows
- A burst pipe is reported at 7:05am with an address and photos.
- All four vans and the office hold the identical job within minutes.
- The nearest plumber replies with a 40-minute ETA from their own address.
- bookings@ keeps the timestamped job record for invoicing.
Why Sinka fits here
- No dispatcher needed for a four-van outfit.
- Damage photos arrive full-resolution on the plumber's phone.
- Subcontractors get copies for a week, revoked when the job ends.
Watch out for
- First-to-claim needs a visible rule (reply-all 'taking 14 Acacia Ave') or two vans roll.
- Customers reply to whoever answered — make sure quotes CC the office for the invoice trail.
