Plumbing Bid Sheet Template: 7 Things It Must Include

Use a plumbing bid sheet template that wins jobs. Here are 7 must-have sections for accurate, professional bids that clients actually approve.

Plumbing Bid Sheet Template: 7 Things It Must Include

If you are sending plumbing bids on a blank invoice form or a basic spreadsheet, you are leaving money on the table. A weak bid sheet makes you look unprepared, invites clients to haggle, and causes problems when scope disputes come up later.

A solid plumbing bid sheet template fixes all of that. It keeps your numbers organized, makes your proposal look professional, and protects you if a job goes sideways. Here are the seven things every plumbing bid sheet needs.

1. Your Business Header and License Info

Put your company name, address, phone number, email, and contractor license number at the top. This is basic, but a lot of plumbers skip the license number. Including it builds credibility immediately and is required in most states before a contract is legally valid.

If you have insurance, list your coverage type there too. Clients and GCs check this stuff before they sign anything.

2. Client and Project Information

Your bid sheet should clearly identify who you are bidding for and what the job is. Include the client name, the property address, a job description, and a bid date.

Also include a bid expiration date. Material prices move fast. Without an expiration, a client can come back six months later and hold you to a price that no longer makes sense.

3. Itemized Labor Costs

This is where a lot of plumbing bids fall apart. If you just write a single lump sum for labor, clients have no idea how you got there. Itemize it.

Break labor down by task or phase:

  • Rough-in plumbing
  • Fixture installation
  • Water heater installation
  • Final connections and testing

List the estimated hours and your hourly rate for each item, or use a flat rate per task. Either way, show your work. It reduces pushback and makes change orders easier to justify later.

4. Itemized Materials List

Do not bury materials in your labor line. List them separately with quantities, unit costs, and total costs per item. This level of detail does three things:

  1. It shows the client exactly what they are getting
  2. It protects you if material costs go up before the job starts
  3. It makes it easy to swap materials if the client wants to adjust the budget

Include a markup line if you are adding margin to materials. Be transparent about it. Most clients expect it, and hiding it causes more friction than showing it.

5. Subcontractor or Equipment Costs

If you are pulling in other trades or renting equipment for the job, those costs need their own line on the bid sheet. Do not fold them into your labor rate without disclosure.

Examples to include here:

  • Pipe cutting or threading equipment rental
  • Permit fees (or note that permits are billed at cost)
  • Any specialty work like gas line inspection or backflow certification

Being upfront about these costs keeps the client from feeling surprised when the invoice comes in.

6. Total Cost Summary and Payment Terms

After your itemized sections, include a clean summary that shows:

  • Subtotal for labor
  • Subtotal for materials
  • Subtotal for other costs
  • Any applicable taxes
  • Grand total

Then state your payment terms clearly. Do you require a deposit? What percentage? When is the final payment due? Do you charge for late payments?

Putting this on the bid sheet means the client has agreed to your terms before work starts. That matters when it is time to collect.

7. Scope Exclusions and Terms

Always include a section that spells out what is NOT included in your bid. This is where most plumbers get burned. The client assumes something is covered. You assumed it was obvious it was not. Now you are in a dispute.

Common exclusions to list:

  • Drywall repair after rough-in work
  • Concrete cutting or patching
  • Trenching or excavation
  • Work outside of the agreed fixture count
  • Any items requiring permits not listed above

Also include a line about how change orders are handled. State that any work added to the original scope will be quoted separately before it begins.

Stop Building Bid Sheets from Scratch Every Time

Putting together a thorough plumbing bid sheet every time you quote a job takes real time. Most plumbers are estimating jobs in the truck, between calls, or at the end of a long day. A template helps, but it still requires a lot of manual entry.
