Estimate. Job agreement. Job list. Change order. Invoice. For small independent plumbers — one truck, solo — who are tired of “we’ll pay you Friday” after the heater is already in. Most unpaid plumbing jobs are not mysteries. There was no signed list of what was in, no deposit, and a “while you’re here” that never got a price. This kit is the paperwork you fill in before you open the wall, and the emails you send if the balance still sits. You get letter-quality HTML you open in Chrome and print to US Letter PDF: estimate, plumbing service agreement (job agreement), a job list that grows, change order, invoice, cash receipt, four late-pay emails, and a spreadsheet that tells you which email is next. Fill in [Your Name] and [Owner Name]. Print. Get signatures. Take the deposit. Stop inventing this on the tailgate. What’s inside Estimate — HTML, print to PDF. Line items, tax, deposit to start, license line. Plus a filled sample so you can see the density. Plumbing service agreement — fill-in-the-blank job agreement. Who, ROC license number, owner mailing address, jobsite and legal description, dates, the job, total including tax, deposit, progress payments, change orders, access, materials, late pay / pause, labor warranty, cancel, copies and cash. Registrar complaint notice in 10-point bold, as Arizona asks for on contractor–owner jobs over $1,000. Template, not legal advice. Job list (Exhibit A) — room, work, material / brand / size, qty, included Y/N, price. Add line / add item / add room / add fixture. Add as many lines as you need. Totals count new rows. Change order — date, extra work found, price change, both sign. Invoice — deposit, progress, or final. Add check, card, Zelle, Venmo, cash, bank transfer, or other, and type your own payment details. License number. Add line. Plus a filled sample (~$2,800 water-heater job). Cash receipt — one page, for the true amount of any cash, because Arizona asks you to hand that over at signing. Storm / insurance addendum — optional extra page. Use only if this job is insurance-paid storm repair. Leave it in the folder for a faucet call. Late-pay emails — day 0, 7, 14, 30. Plumber to homeowner, not lawyer to file. Job tracker — .xlsx with formulas (balance, which email next) and a .csv for Google Sheets. Type in the next empty row. Start-here guide and a license / disclaimer. Buy once. Use on every job. No subscription. No dispatch app. Who it’s for US one-truck and solo plumbers who invoice homeowners and want papers that look like they charge for the work. Who it’s not for Multi-crew shops that need dispatch, GPS, or a shop OS Anyone looking for a lawyer, a license, or building-code advice (this is a template kit; see the disclaimer) People who want Canva templates with 14 colorways Roofers looking for a storm-chaser pack (the storm page is one optional addendum, not the product) Use AI to write the job description Stuck on what to put in the job list? Paste what you told the owner into ChatGPT, Claude, or any AI. Ask it to turn that into short lines: room, work, material, qty. Paste those lines into the job list. Read them. They have to match the job before you print. How to use it Fill the agreement once. Set your ROC number, late fee, and warranty days. Write the job list for this house. Use AI if you want help with the wording. Get both signed. Give the owner a copy. Take the deposit. Do the work. Change orders in writing. Invoice. Log the job. If the balance ages, send the matching email. Disclaimer Template. Not legal advice. Not a substitute for a lawyer in your state, including an Arizona contractor attorney. Not a contractor license, not building code, not permit advice. Using this file does not make you licensed and does not mean the job will pass inspection. Have a lawyer in your state read it before a real job. For the purchaser’s own plumbing practice. One purchaser, one practice. Not for resale as a template kit.
