For the one-person plumbing operation
Your 24/7 apprentice is on the truck.
Mainbrace is the AI-native operations stack for the solo plumber. It answers every inbound call, triages emergencies from the photo your customer sends, drafts and sends the estimate, books the job, chases the invoice — and gets sharper at every one of those with the next job you close.

How it works
One vertical pipeline, end to end.
Not five bolted-on tools. One loop — answer, triage, quote, book, invoice, learn — that compounds knowledge week after week so the third water-heater swap is faster than the first.
A 24/7 agent picks up in your shop name, screens emergencies, and books a window into your calendar before the caller hangs up.
The caller texts a photo. The agent classifies the fault against your previous work and surfaces a likely cause with a labor band.
A regional-priced estimate is drafted in your voice, sent in under six minutes, and parked beside the ticket.
The job lands on your schedule and the invoice is dispatched. A polite sequence handles late payment without you picking up the phone.
The call, the photo, the diagnosis, the parts, the close — all of it is logged into a private knowledge base you own.
The learning loop
The third water-heater beat the first.
Every closed job feeds a private knowledge base scoped to your shop — patterns, parts, regional markup, tone. Nothing crosses over. The agent surfaces regional pricing patterns without manual tuning and recalls the call you took last March like it took it this morning.
- Private knowledge, scoped to your shop — no cross-shop training.
- Regional pricing patterns surface from your own closes.
- Diagnostic recall improves with every same-pattern job.

One tier to start, two to scale with you.
The entry tier follows the de-facto trade-AI standard. Higher tiers follow the proven setup-plus-recurring shape — a real apprenticeship, not a monthly subscription.
