Common headaches for plumbers, and what this does about them

1

Writing up a water heater swap at 9pm after a full day of calls

Type it rough on your phone. It comes out as a proposal in about two minutes, with your company name, terms, and warranty already on it.

2

Customers who "need to think about it" and never text back

You get an alert when they open it and when they sign. If they go quiet, a follow-up goes out from you on day 3 and day 7.

3

Losing a job to a company with a nicer-looking estimate

Your proposal goes out with your company name, license, terms, and warranty, a signature box, and a deposit button. It looks like it came from a company with an office.

What to spell out on a plumber bid

Useful whatever you write your bids in. These are the lines that keep a job from turning into an argument.

Put it in writing
  • Where the shutoff is, and how long the water will be off
  • Fixtures by brand and model, or "customer supplied"
  • Whether haul-off of the old unit is included
  • What happens if you open a wall and find more than expected

Water heater and repipe work often needs a permit. Say on the bid who pulls it and whether the fee is in your price.

Questions from plumbers

Before you sign up.

Can I add my plumbing license number?

Yes. It goes in your company profile once and shows on every proposal, which many customers look for.

What about jobs where I find more once I open the wall?

Write the bid for what you know. If the scope changes, write a second bid in two minutes and send it the same way. Both stay in your records.

Is the signature legally binding?

Yes. The customer types their full name and clicks Accept, and we record the name, date, time, and the exact proposal they agreed to. That meets the U.S. E-SIGN Act, the same law behind DocuSign.

Does my customer need an app?

No. They tap the link in your text or email, the proposal opens in their phone's browser, they read it and sign.

Does it change what I wrote?

It fixes spelling and lays your notes out cleanly. It does not add scope, exclusions, or promises you didn't make.

What does it cost?

$29 a month, flat. Unlimited proposals. Your first 30 days are free with no card, and you can cancel anytime.
