OnCall Office
Never miss another emergency call.
Your phone rings first. We only take what you miss.
OnCall Office answers the calls you can't get to — by text and by phone — and books the job into your calendar. Built for septic, well-pump, water-treatment and specialty contractors.First 30 days free. No contract. 30-min setup. Cancel any time.
Say you're a septic contractor and a homeowner has a backed up tank...
You're on the truck. The phone rings. You can't get it.
The homeowner doesn't leave a voicemail. They call the next company on Google. Small contractors miss a large share of their inbound calls, and most of those callers never call back. Every one of them is a pump-out, a repair, or a replacement that went to someone else.
How OnCall Office works
Step 1 — Your phone rings first. Answer like you always do. Calls you can’t get to (no answer, busy, or no signal) forward to your OnCall line.
Step 2 — Your "office" picks up those missed calls, day or night. A phone assistant that sounds like your office answers in your company’s name. It finds out what’s wrong, gets the address, quotes standard jobs from your price sheet, offers the earliest open time and books it once the caller says yes. You receive a text notifying you of the booking and/or the lead's information. Anything non-standard gets flagged for you with nothing promised until you confirm. Hang-ups get a text-back so the lead isn’t lost.
Step 3 — Emergencies come straight to you. Sewage backup, alarm, no water: during business hours we try to put the caller through to you; after hours we call and text your cell and tell the caller you’ll call back. Every caller gets a text afterward: their booking confirmation, or a note that you’ve been notified.
What you get
A text the moment something needs you: every booking, every emergency, every caller who asked for you.
A daily recap of calls handled and jobs booked
A live dashboard of calls handled, jobs booked, and estimated revenue
Spanish-language support for callers who need it
Setup on your existing phone number — no new phone system, no app
Customers can text to book or reschedule, and it remembers their phone call.
What we never do
We never quote non-standard jobs, never promise arrival times you haven't set, never give out your cell number, never tell a customer someone is on the way and never give advice beyond your own personalized FAQ. Anything unusual, we tell the caller you'll confirm and flag it to you.
