Free plumbing proposal generator
Plumbing quotes are either a flat price for the job or time plus materials. Customers trust the quote more when parts, labor and permit are on separate lines. Here is how to set one up.
Updated October 2026. By AI Automation Education.
Our free generic generator prices by quantity times rate. For plumbing, enter the quantity in the width box and 1 in the height box, and your price per fixture or per hour as the rate.
How plumbing work is usually priced
Flat-rate pricing gives the customer one number and puts the risk on you, so use it for repeat jobs you know well. Time and materials fits repairs where the problem is unclear. Either way, list parts and labor separately so the price looks fair.
What a good plumbing proposal includes
- Exact fixtures or parts, with brand and model where it matters
- Labor as a flat price or hours times your rate
- Permit and inspection if the job needs them
- What is not included, such as drywall repair or tile work
- Warranty on labor and on parts
- How you handle surprises behind the wall

Frequently asked questions
Should plumbers quote flat rate or time and materials?
Flat rate works for jobs you do often, like water heaters or fixture swaps. Time and materials suits repairs where the cause is unknown. Many shops use flat rate for known jobs and time and materials for diagnostics.
What should a plumbing estimate include?
Parts, labor, permit, what is excluded, warranty and an expiry date. Name the brands of major fixtures and say whether you or the customer supplies them.
Can I use the free generator for plumbing jobs?
Yes. It multiplies quantity by rate. Put the number of fixtures or hours in the width box, 1 in the height box, and your price per unit as the rate. It stores nothing, so save the PDF before you leave.
How do I protect myself from hidden problems?
Add a line in the terms saying work behind walls or floors may change the price, and that you will get approval in writing before extra work.
