Comparison · Rosie
Mainbrace vs Rosie — built for plumbing, not any small business.
Rosie answers calls well. Mainbrace answers calls well, then triages the photo against your previous plumbing work, drafts a regional-priced quote in your voice in under six minutes, and chases the invoice at day 3, 7, and 14 until it clears. Side-by-side, row by row, here is what plumbers actually switch for.
What solo plumbers get from Mainbrace that Rosie doesn’t
Four plumber-specific wins, one per row of the pipeline.
Rosie is a generalist AI receptionist. Mainbrace is built for the one-truck plumbing shop. Every win below comes from the same promise: from the first call to the last invoice, the system acts like a plumber — not a generic small-business bot.
Trade-specific photo triage — the caller’s photo classified against your prior plumbing work.
Plumbing-aware quote generation — regional-priced, drafted in your voice in under six minutes.
Day 3 / 7 / 14 invoice follow-up — an automated polite sequence that pauses the moment the bill is paid.
A private job-by-job knowledge base that sharpens with every closed job — owned by your shop, never pooled.

Why plumbers switch
Four reasons Rosie runs out of runway on a plumbing truck.
Generic answering is the right first step. It is not the second step. Here is what the next step actually requires — and what a plumber gets when they pick Mainbrace instead.
