Repair approvals signed before the wrench comes out
Plumbing work starts with a call that can't wait and ends with a customer who wants to know why the bill says what it says. A signature before the work settles that. SignMaster puts your repair approvals, replacement contracts and membership agreements on the phone your plumbers already carry, and customers sign without making an account.

What a plumbing company gets signed
| Document | When | Who signs, and how |
|---|---|---|
| Repair authorization | After the diagnosis, before any work | The customer on site, or the owner by link |
| Water heater replacement | Before the old tank is drained | The homeowner, in person at the tank |
| Drain or sewer cleaning release | Before you snake or jet an old line | The homeowner, in person |
| Sewer line replacement contract | After the camera inspection | Both owners, often by link once they've watched the video |
| Membership plan | At sign-up, then every year | A public link to join, bulk send to renew |
| Commercial service agreement | Yearly, with a restaurant or building | The manager by link, with accounts payable copied |
On the service call
The plumber finds the leak, opens the repair template on their phone and types the fix and the price, or asks Alana to fill it from one sentence. They send it, choose Sign in person and hand the phone over. The customer reads the price, initials the line that says what isn't included, and signs. In the iPhone and iPad app, signing mode can't be swiped away, and only the plumber's Face ID or passcode ends it.
Replacement choices fit on one page. A radio group lets the homeowner pick a standard tank, a high-efficiency tank or a tankless unit, checkboxes add an expansion tank or a new shut-off valve, and a calculated field shows the total as they choose. Conditional fields keep the tankless venting lines hidden unless that option is picked.
Jetting an old line?
Cast iron and clay pipe can be in worse shape than the camera shows. Before you clean one, have the homeowner initial a short release that says what you saw and that cleaning can expose damage that was already there. Put it in the repair template as a required initials field, so nobody skips it on a busy day.
When the person paying isn't the one who called
Tenants, house sitters and grown children call plumbers too. If the owner isn't standing in the wet kitchen, send the authorization to them by link from the driveway. They open it on any phone or computer and sign, and the tenant can sign the same envelope in person on your phone. When a property manager must approve before you open a wall, put them first in the signing order and let the tenant's turn come after.
Membership plans and commercial accounts
- Sign-ups: turn your membership agreement into a public signing link or QR code for invoices and your website. Each customer who joins signs their own copy.
- Renewals: bulk send the renewal from one CSV of members. Columns fill each member's name, address and price, and labeled text boxes carry wording that changes per row, like the number of visits a year.
- Restaurants and buildings: add a signer group so any one of the client's managers can sign for the company, and copy accounts payable so they get the signed PDF too.
- Records: on paid plans, the template's Responses tab lists every member's answers in one table, ready to export as a CSV.
No agreement of your own yet? Start from the plumbing service agreement in the template library. Use this template opens it in SignMaster with the blanks marked, so you fill in your terms once and send it from then on.
Pricing for a plumbing shop
A one-van plumber can run on Solo: $15 a month, unlimited envelopes and bulk sends of up to 250 rows. Crew is $49 a month for 5 people, so plumbers and the dispatcher all send from shared templates, and each extra person is $8 a month. Free gives one person 3 envelopes a month to try on real calls. New workspaces get 14 days of Crew free, no card. Compare plans.
What SignMaster leaves to your other tools
- It doesn't hold your flat-rate price book or build the estimate. Bring the price, or the PDF your field software makes.
- It doesn't dispatch, schedule or take card payments.
- It emails signing links. To reach a customer by text, copy their link and send it from your own phone.
- It doesn't pull permits or tell you which jobs need one.
Questions? Answers.
Can a plumber get a repair approved on site before starting?
Yes. Fill in the repair from a template, send it and choose Sign in person. The customer signs on the plumber's phone, and the signed PDF reaches everyone by email once the last signature is in.
Who should sign when a tenant calls for a repair?
Whoever your policy says pays. Send the authorization to the owner or property manager by link, and add the tenant to the same envelope if you want their signature as well. Signing order decides who goes first.
Can customers join a plumbing membership plan online?
Yes. A public signing link turns your membership agreement into a page anyone can fill in and sign, each in their own envelope. Share it as a link or print the QR code on your invoices.
Do plumbers with Android phones need an app?
No. There's no Android app; Android phones send envelopes and run in-person signing in the browser. The iPhone and iPad app adds scanning with searchable text and a Face ID lock on signing mode.
