Irrigation Invoice Template: Sprinkler Repair + Install
Irrigation invoice template for sprinkler installs per zone, spring startups, winterization blowouts, backflow tests and repairs, with a worked example.
Quick answer: An irrigation invoice bills a customer for sprinkler system work: new installations priced per zone, spring startups, fall winterization (blowouts), backflow testing and repairs. It lists the service date, zones worked, parts such as heads, valves and controllers, labor, trip or service charges, payments received and the balance due, plus notes on settings and next service.
Irrigation work is seasonal and high volume: a busy company may run dozens of startups or blowouts a day in spring and fall, then large installs in between. Clear invoices keep cash flowing through that rush and reduce calls from customers asking what was done. This guide covers what to include, how to price installs, startups, winterization and repairs, and a full worked example you can recreate in our free invoice generator.
What is an irrigation invoice?
An irrigation invoice, also called a sprinkler invoice or sprinkler repair invoice, is the bill an irrigation contractor, landscaper or plumber sends after working on an automatic watering system. Customers include homeowners, HOAs, commercial property managers, sports fields and municipalities.
Many irrigation companies also offer lawn and landscape services, so the invoice may appear alongside mowing or planting work. Our landscaping invoice template and lawn care invoice template cover those services. For backflow and water supply connections that fall under plumbing rules, see the plumbing invoice template.
What should a sprinkler or irrigation invoice include?
| Section | Details |
|---|---|
| Business details | Company name, phone, address, irrigator or contractor license and backflow tester certification where required |
| Customer and site | Name, service address, gate code or access notes, HOA or property manager reference |
| Service type | Install, startup, midseason check, winterization, repair, backflow test |

How much do irrigation contractors charge?
Prices vary by region, water source, soil and labor costs. Rather than quote national figures that may not fit your market, set per zone and per visit rates from your costs. The table shows the most common pricing structures.
| Service | Common pricing method | Invoice notes |
|---|---|---|
| New system installation | Per zone, plus controller, backflow and tap | Zone count, spray vs rotor vs drip, sleeves |
| Spring startup | Flat fee up to a set number of zones, plus per extra zone | Leaks found, controller programmed, adjustments |
| Fall winterization (blowout) | Flat fee up to a set number of zones, plus per extra zone | Zones blown out, backflow drained |
| Repairs | Service call plus hourly labor and parts | Parts by zone, time on site |
| Backflow test | Flat fee per device | Device type, serial, pass/fail, report filed |
| Controller upgrade | Controller price plus install and programming | Model, stations, sensor |
| Drip conversion | Per zone or per bed | Emitters, tubing, pressure regulator, filter |
| Seasonal service plan | Annual fee or installments | Visits included, repair discount |
If you charge a minimum or trip fee, explain it on your estimate and invoice. The guides to the service call fee and billing for travel time show how other trades present it.
Invoicing installs per zone
A zone is a group of sprinkler heads or drip emitters controlled by one valve. Because each zone needs a valve, pipe, wire, heads and trenching, per zone pricing tracks labor and material reasonably well. Typical line items for a new system:
- Zones installed, split by type: spray, rotor, drip
- Main line from the tap or meter to the valve manifold
- Backflow preventer installed (type and size) and permit
- Controller, rain sensor or soil moisture sensor
- Sleeves bored under driveways or sidewalks
- Locates, permits and water tap fees at cost
- Restoration of lawn after trenching or pulling pipe
Here is how per zone pricing might add up on an illustrative new residential system with six spray zones, two rotor zones and one drip zone. Using example rates of $550 per spray or rotor zone and $450 per drip zone, the zones total $4,850 (8 x $550 plus $450). Add a smart controller installed and programmed at $380, a pressure vacuum breaker with permit at $420, two driveway sleeves at $150 each and lawn restoration at $250, and the contract total is $6,200. On the invoice, each of those items appears as its own line, so the customer can see that the zones are only part of the price and can compare your bid fairly with another contractor's.
Record the final zone map on or with the invoice: which valve controls which area, where valve boxes are, and the controller station for each zone. It saves time on every future service call and is one of the most appreciated things you can hand a new customer.
Large installs usually need a deposit and sometimes progress payments. See our guides to the deposit invoice and progress billing.
Startups, winterization and backflow testing
Spring startup
Startup invoices should list the date, steps taken (water turned on slowly, each zone run, heads adjusted, leaks noted), the controller program set and any repairs needed. Separate the flat startup fee from repairs so the customer can approve extra work.
Fall winterization
In freezing climates, compressed air blowouts clear water from pipes and heads. Note zones blown out, that the backflow device was drained or protected, and the controller set to off. Many companies schedule thousands of these a season, so a quick, consistent invoice format saves hours. Batch similar invoices at the end of each day with sequential numbers from the invoice number generator.
Backflow testing
Backflow preventers protect the public water supply from contamination. Many water utilities require annual testing by a certified tester and a test report filed with the utility. List the device type (for example pressure vacuum breaker or reduced pressure zone assembly), serial number, test result and any utility filing fee. If a device fails, quote the repair separately.

Whether parts, labor or maintenance are taxable depends on your state, so treat the tax line as an example. Our sales tax calculator helps with the math once you know the rate.
How to create an irrigation invoice step by step
- Choose the service type and enter the date and site.
- Record system details: zones, controller, backflow device.
- Add the flat fee for startup or winterization, plus extra zones.
- List repair labor by time and each part by zone.
- Add backflow test results and filing fees.
- Apply sales tax according to your state's rules.
- Add notes about settings and next service.
- Send the PDF from the free invoice generator the same day, or batch invoices at day's end.
Water efficiency and rebate paperwork
Many water utilities offer rebates for efficient irrigation equipment, especially smart controllers and high efficiency nozzles. The EPA's WaterSense program labels irrigation controllers and spray sprinkler bodies that meet its efficiency criteria, and utilities often require a WaterSense labeled model and an itemized invoice showing the model number. Put the model, number of stations and installation date on the invoice so your customer can apply.
Licensing also matters for paperwork. In Texas, for example, irrigation installation requires a license from the Texas Commission on Environmental Quality, and other states regulate the work through plumbing or landscape contractor boards. Show your license number on the invoice where it is required.
Seasonal service plans and recurring billing
Service plans smooth out irrigation income and lock in customers before competitors call. A typical residential plan includes spring startup, one midseason check and fall winterization, often with priority scheduling and a discount on repair labor. Commercial and HOA plans may include monthly inspections during the watering season with a written report for each visit.
There are three common ways to bill a plan:
- Annual prepayment. One invoice at the start of the season, sometimes with a small discount for paying upfront.
- Per visit billing. An invoice after each included visit at the plan rate, plus any parts and repairs.
- Monthly installments. Equal payments across the season, useful for HOAs and commercial sites with monthly budgets.
Whichever you choose, list the visits included, the repair discount and the cancellation terms on the first invoice. Show what each later invoice covers, for example "Plan visit 2 of 3: midseason check", so customers can see what remains. Our guide to recurring payments explains autopay options that reduce chasing.
Billing HOAs and commercial properties
Large properties bring bigger invoices and stricter approval processes. Expect to provide a certificate of insurance, a W-9, and invoices that reference the property name, a purchase order or work order number and the manager who approved the work. Inspection reports with zone maps, photos of broken parts and notes on water waste help managers approve repairs quickly.
Set an approval threshold in your service agreement: repairs below a fixed dollar amount can be done on the spot, while anything above it needs written approval. This avoids return trips for small fixes and protects you from disputes on larger ones. Bill each property separately when one management company oversees several sites, because each site usually has its own budget.
Common irrigation invoice mistakes
- No zone details. "Fixed sprinklers" tells the customer nothing. Name the zone and part.
- Unapproved repairs during a startup. Get approval before replacing valves or controllers. A simple signed work order helps.
- Missing backflow serial numbers. Utilities reject reports without them.
- Late invoices in peak season. Send invoices daily during startup and blowout rushes.
- Unclear seasonal plan terms. List the visits included and what is extra.
- Wrong tax treatment. Parts, labor and installs can be taxed differently.
- No payment terms for HOAs. State the terms and late fee. Our guide to invoice payment terms explains options.

Frequently asked questions
How do irrigation contractors usually price new sprinkler systems?
Most price new systems per zone, because each zone needs a valve, pipe, heads and wiring, and labor scales with the number of zones. The per zone price is then adjusted for soil conditions, drip versus spray zones, the controller, a backflow preventer, the water tap and any sleeves under driveways or walks. Itemize these parts on the invoice so customers can compare against the estimate.
What should a sprinkler winterization invoice include?
Include the service date, the method (usually compressed air blowout), the number of zones blown out, whether the backflow device was drained or insulated, controller settings changed to off or rain mode, and the price. Many companies bill a flat fee up to a set number of zones plus a charge per extra zone. Add a note that the system must not be turned on until spring startup.
Do I need a license to install irrigation systems?
It depends on the state and sometimes the city. Texas, for example, requires irrigation installers to hold a license issued by the Texas Commission on Environmental Quality, and backflow testing usually requires a certified tester. Other states fold irrigation into plumbing or landscape contractor licensing. Put your license number on invoices where required, and check local rules before connecting to a potable water supply.
How do I bill for irrigation repairs?
Repairs are often billed with a service call or trip charge, labor in quarter or half hour increments after the first hour, and parts such as heads, nozzles, valves, solenoids and fittings. List each part and the zone where it was installed. Wire locating and valve finding can take time, so many contractors bill those hourly and note it in their terms.
What is backflow testing and should it be a separate line?
Backflow testing checks that the device preventing irrigation water from flowing back into the drinking water supply works correctly. Many water utilities require annual testing by a certified tester and a submitted test report. Bill testing as a separate line, list the device type and serial number, record pass or fail, and note any filing fee the utility charges.
Can I sell seasonal irrigation service plans?
Yes. Many companies sell annual plans covering spring startup, a midseason check and fall winterization, often with a discount on repair labor. Bill the plan upfront or in installments and list each visit on the invoice. Make clear that parts and repairs beyond adjustments are extra, and state what happens if the customer cancels part way through the season.
Should I charge sales tax on irrigation work?
Sales tax rules vary. Some states tax repair parts and certain landscaping services, while new system installation may be treated as a real property improvement where the contractor pays tax on materials. Seasonal maintenance may be taxable in some states and exempt in others. Check your state's guidance and apply tax line by line where required.
How do I invoice a smart controller upgrade?
List the controller make and model, the number of stations, any rain or soil moisture sensor, Wi-Fi setup and programming time. Note if the controller is WaterSense labeled, since some water utilities offer rebates for labeled controllers and ask for an itemized invoice. If the customer bought the controller, bill only installation and programming and say so.
