Plumbing Invoice Template: Fixtures, Hours, Materials

Short answer: A plumbing invoice template needs two kinds of lines on one page: fixture work priced per unit (toilet reset, lavatory faucet, 50-gallon water heater) and repair work billed as a call-out fee plus hours. Name the material on every pipe line — PEX, Type L copper, or PVC — with the linear feet and the fitting count. Put the after-hours premium, the permit, and any wall opening and patching on their own separate lines.

Plumbing is the one trade where the customer can watch you work for two hours and still have no idea what you did, because most of it happened inside a wall or under a slab. The invoice is the only record of it. The general field checklist in what to include on an invoice still applies, and the paid-in-full document is a separate piece of paper from the bill itself, which is the distinction in invoice vs receipt.

What does a plumbing invoice template need on it?

Fill every block below before you pull out of the driveway. The material and access blocks are the two that plumbers skip and then argue about later.

Block	What it reads
Job and access	Address, unit number, floor, slab or crawlspace, where the main shutoff is
Fixtures worked on	Named and counted: toilet, lavatory, tub/shower valve, kitchen sink, 50-gal water heater
Findings	Measured values: static pressure in psi, PRV setting, camera footage to the break, heater serial
Materials	Type and size: 1/2 in PEX-A, 3/4 in Type L copper, 2 in PVC DWV, with feet and fitting count
Valves	Angle stops, full-port ball valves, PRV, thermal expansion tank, each by the unit
Labor	Call-out fee plus hours at your rate, or a flat price per fixture
Access and restoration	What you opened, how big, and exactly how you left it
Demolition and haul-off	Old galvanized, cast iron, the removed water heater, tile spoil
Permit and inspection	At cost, with the permit number printed
Totals and terms	Material subtotal, labor subtotal, tax, deposit applied, balance due
License	Your plumbing license number in the footer

Findings should be numbers, not adjectives. Static pressure at 96 psi with no PRV. Water heater manufactured 2009 per the rating plate. Camera shows a break at 31 feet from the cleanout, offset joint, roots present. A homeowner cannot argue with a measurement, and the next person to open that wall can read what you found.

How do I put fixture lines and hourly lines on the same invoice?

Split the invoice into two blocks with a subtotal on each. Work you have done a hundred times gets a per-fixture price. Work behind drywall or under concrete gets a call-out fee plus hours, because you could not see it when you quoted it.

Block	Line	Unit	Qty
Flat-rate fixture	Toilet pull and reset — new wax ring, closet bolts, 1/4-turn angle stop	each	2
Flat-rate fixture	Lavatory faucet remove and replace, fixture supplied by owner	each	1
Time and material	Locate and expose leak, kitchen wall	hour	1.5
Time and material	1/2 in PEX-A hot and cold rerun to sink	linear ft	34
Time and material	PEX-A expansion fittings, elbows, drop-ear at valve	each	11
Access	Open drywall 24 in × 18 in, kitchen side	each	1
Haul-off	Cut sections of corroded galvanized, removed to shop	job	1

The rule that keeps this readable: one line carries one pricing method. A line is either a fixture price or an hourly price, never a fixture price with hours quietly added into it. When a homeowner questions the bill, they are almost always questioning a single line, and you want to be able to point at it and say what it covers.

Print the two subtotals separately for a second reason: many states tax materials and not labor on real property work. Confirm the treatment where you work rather than trusting whatever the invoice app defaults to.

Why should the invoice name the pipe material?

Because the price gap between materials is larger than the price gap between plumbers. A customer holding three bids where one is copper and two are PEX is not comparing the same job, and if your invoice says only “pipe and fittings” you have handed away the reason your number was higher.

Material	Where it belongs	How the line should read
PEX-A, expansion fittings	Hot and cold supply, repipes, tight retrofits	”1/2 in PEX-A, 34 ft, 11 expansion fittings”
PEX-B, crimp or clamp ring	Same service, different fitting method and cost	”3/4 in PEX-B, 22 ft, 9 crimp fittings”
Type L copper	Supply where code, the location, or the customer calls for the heavier wall	”3/4 in Type L copper, 18 ft, 12 sweat fittings, 2 ball valves”
Type M copper	Thinner wall than L; restricted underground in many jurisdictions	Name the type, never just “copper”
CPVC	Hot and cold supply where it is accepted	”3/4 in CPVC, 16 ft, solvent weld”
PVC, DWV grade	Drain, waste, and vent only — not a hot supply material	”2 in PVC DWV, 12 ft, one san-tee, one cleanout”
Removal	What you took out	”Removed 9 ft of 2 in galvanized drain, corroded closed”

Drain sizes belong on the line too, because the material cost and the labor to fit it are not the same at every diameter: 1-1/2 in for a lavatory trap arm, 2 in for a shower or kitchen line, 3 in or 4 in for a toilet. Fitting count matters as much as footage. A 40-foot run with three 90s and a 40-foot run with fourteen fittings and two wall penetrations are different days of work, so either list the fittings or say how many the line includes.

When you supplied the fixture, name the model and its rating. A toilet carrying the EPA WaterSense label is capped at 1.28 gallons per flush against the 1.6 gpf federal maximum, and a water utility rebate form asks for exactly that line off your invoice.

How do I bill an emergency or after-hours call?

The premium goes on its own line, never buried in a higher hourly rate that the customer discovers by comparing two invoices.

Hours category	How the invoice reads
Standard weekday	”Labor 2.5 hr” at your posted rate
After hours	Base hours, then a separate line: “After-hours premium, 6 PM–7 AM”
Weekend or holiday	Same split, base hours plus a named premium line
Emergency dispatch	”Emergency call-out, 2 hr minimum” as its own line, quoted on the phone before you roll

Two more lines earn their keep on a night call. Write the time the water was shut off and the time it came back on — that single detail settles most landlord and tenant disputes about what the flood cost. And when the visit was a stop-the-water visit, say so plainly: “Isolated and capped 1/2 in supply to hall bath. Bath out of service. Repair quoted separately.” Emergency work often splits into two invoices, one to make it safe that night and one for the repair when the part arrives.

Access difficulty deserves the same honesty. A water heater on the third floor with no elevator, a crawlspace you could not stand up in, a shutoff buried under a deck — put it on the invoice as a stated line rather than padding the hours and hoping nobody asks.

How do I charge for opening and patching a wall or floor?

Getting to the pipe is work, and leaving the hole is a decision the customer has to make in writing. Give access its own line, then state the finish level in words that cannot be misread.

What you are selling	The words on the invoice
Access only	”Wall left open for inspection. Patch and paint by others.”
Patch to tape	”Drywall replaced, taped and mudded. Sanding, texture, and paint not included.”
Patch to paint-ready	”Drywall replaced, finished, and sanded. Paint not included.”
Tile or stone	”Tile removed for access. Owner supplies replacement; match not guaranteed.”
Concrete slab	”Slab cut 3 ft × 2 ft, spoil hauled, patched back to grade. Finish flooring by others.”

Never promise a tile match, and never let “we’ll patch it up” stand as the only record of what patching means. When a drywall sub handles the close-up, price it as a pass-through line with their scope named — the per-square-foot logic in drywall estimate per square foot is what that number comes from, and it is worth understanding before you mark it up.

Where do permits, inspections, and tests go on the invoice?

Permits are a pass-through at cost with the number printed on the invoice. The inspection is its own line, and a failed inspection revisit caused by another trade is a billable return trip.

Routine repairs generally do not need a permit. Water heater replacement, repipes, sewer replacement or lining, gas line work, and new fixtures on new drain lines usually do. Verify with the authority having jurisdiction rather than copying the shop across town, because this varies by city, not just by state.

Two documents ride along with specific jobs. A water heater changeout invoice should name the T&P discharge line, the expansion tank if the system is closed, and the seismic strapping if your jurisdiction requires it. A backflow assembly test invoice should carry the assembly make, model, size, and serial, the test readings, and confirmation that the report went to the water purveyor. Put your license number in the footer of everything; many jurisdictions require it on invoices and contracts.

When does a repipe or remodel need a project invoice instead?

	Service call	Repipe, remodel, or sewer
Priced from	The failed fixture or line	Fixture count and linear feet
Unit	Call-out plus hours, or flat per fixture	Per fixture rough-in and trim-out, per foot of pipe or trench
Approval	Verbal on site	Signed scope with named allowances
Billing	Due on receipt	Deposit, draw at rough-in inspection, balance at trim-out
Change orders	Rare	Written and signed before the work happens
Unknowns	Few	Everything under slab, inside walls, or behind tile

New construction and full repipes price by fixture count, not by hours, and the invoice reads that way: “11 fixtures, rough-in complete, inspection passed” then a separate trim-out invoice when the fixtures go on. Splitting the money at the inspection is also what keeps a builder current with you rather than ninety days behind, which is half the battle described in how to get clients to pay.

Anything you cannot see before you open it goes in as a conditional line with a stated allowance: “Includes 8 ft of 2 in PVC replacement under slab. Additional footage billed per foot, photographed before and after.” That sentence turns a fight into a math problem, which is the point.

What do I keep after the plumbing invoice goes out?

Keep the supply house receipt for the material, the permit and inspection card, photos of the pipe before and after with a tape in frame, and the camera stills if you scoped a line. The supply house receipt settles any markup question and supports the deduction at tax time; the photos are what a warranty claim or an insurance adjuster asks for a year later.

Keel is an iOS app that runs entirely on the device: no account, no bank connection, no cloud, no login, and an App Store privacy label that reads Data Not Collected. On-device matters more in this trade than in most, because half the invoices get written in a crawlspace, a mechanical closet, or a slab-on-grade garage where there is no signal to sync to anything. You write it where you are standing — the fixture lines, the hour lines, the psi reading you just took, your logo and your numbering, and a payment link rendered as a QR code the homeowner scans off your screen before you have loaded the wet vac. Photograph the supply house receipt at the counter and Apple Intelligence reads it on the phone; the drive from the night call to the next stop is logged as a trip. Freeboard shows cash minus tax reserve minus committed invoices minus buffer, so a deposit on a repipe you have not roughed in yet does not read as money you can spend. The ledger is append-only and hash-chained, so the shut-off time you recorded at 2 AM cannot quietly change three months later, which is exactly what an adjuster is checking for. At year end it exports as one file, or as the Accountant Pack: a CSV plus a one-page summary PDF.

Frequently asked questions

What should a plumbing invoice include?

Job address and access notes, every fixture you touched by name and count, measured findings like static pressure and camera footage, materials named by type and size with linear feet and fitting count, valves by the unit, labor as a call-out fee plus hours or a flat fixture price, wall or floor opening with the restoration level stated, permit at cost, subtotals for material and labor, and your license number.

Should I charge a call-out fee and an hourly rate?

Yes, as two separate lines, and say both numbers on the phone before you drive. The call-out covers showing up with a stocked truck; the hours cover the work. Keeping them separate stops the customer from doing the math on a twenty-minute repair and deciding your hourly rate is unreasonable. State any minimum, such as a one-hour or two-hour emergency minimum, on the line itself.

Do I have to list the pipe material on the invoice?

No rule forces it, but list it anyway. PEX-A, PEX-B, Type L copper, CPVC, and PVC carry different material costs and different labor, and a customer comparing bids has no way to see that unless you write it. The material and diameter also tell the next plumber what fittings to bring, and appraisers and home inspectors read those lines years later.

Who pays to fix the wall after a plumbing repair?

Whoever the invoice says, which is why the restoration level belongs in writing before you cut. Access only means the wall is left open and patching is by others. Patch to tape means drywall replaced, taped, and mudded, with texture and paint excluded. Tile is its own conversation: remove for access, owner supplies replacement, and no match guaranteed on discontinued tile.

Can I charge more for an emergency plumbing call at night?

Yes, as long as the premium is quoted before you roll and printed as its own line rather than hidden in a raised hourly rate. Name the window on the invoice, such as after-hours 6 PM to 7 AM, weekend, or holiday. Also record the time the water was shut off and restored, because that timeline is what disputes over flood damage actually turn on.

How do I invoice a job when I cannot see the pipe until I open it?

Price the part you can see and write the rest as a conditional line with an allowance: a stated number of feet of replacement included, additional footage billed per foot with before and after photos. Get that language agreed before demolition starts. Once the wall or slab is open, photograph what you found and reference the photo on the final invoice line.
