Invoice residential pressure washing the day the work is done: each surface on its own line with its method (soft wash or pressure), size and quoted price, add-ons approved on site as separate lines, notes on conditions such as oxidation or stains that didn't fully lift, and before-and-after photos. Collect on site, or by pay link if the customer was out. Bill HOAs, property managers and commercial accounts on agreed terms, citing their work order or PO, after your W-9 and insurance certificate are on file.
Pressure washing businesses bill three kinds of customers, and each one pays differently. A homeowner wants to see a clean house and pay once. An HOA or property manager pays through an accounts payable department that wants paperwork first. A commercial account pays on terms for visits that often happen after closing, with nobody there to see the work.
| Homeowner | HOA or property manager | Recurring commercial | |
|---|---|---|---|
| When you invoice | The day the job is done | When the work order is complete | Per visit or monthly, per the agreement |
| Who approves the work | The homeowner, on the estimate | The manager or board, on a work order | The service agreement, plus any PO |
| Paperwork before payment | Usually none | W-9, certificate of insurance, vendor setup | W-9, certificate of insurance, vendor setup |
| When you get paid | On site, or by pay link that day | On their payment cycle | On agreed terms, such as net 30 |
Your square-foot and per-surface rates come from how to price pressure washing jobs. Here the job is turning a finished wash into a bill the customer pays the same day: what to list, which photos to attach, and when to send it.
Write the invoice so someone who wasn't there can tell what was cleaned, how it was cleaned and what condition it was in. If your estimate follows how to write a pressure washing estimate, copy its surface names and disclaimers word for word, so the two documents never disagree.
Residential jobs are usually paid when the work is done. The twist in this trade is that the customer often isn't home: exterior work needs water and an unlocked gate, not the homeowner. Decide at booking how you'll handle both cases.
When the customer is home, walk every surface together before you pack up. Check flatwork as it dries, since cleaner marks and missed spots often show only then. Point out the conditions you noted, then present the invoice and take payment.
When the customer is out, your photos stand in for the walkthrough. At booking, agree on either a card on file with written permission to charge it when the job is done, or a pay link sent when you finish. Send the invoice with before-and-after photos before the trailer leaves the street, while you can still touch up a spot they question. Payment methods and reminders are covered in how to get paid faster.
Example: A homeowner who will be at work books a two-story vinyl house wash, $450, and the driveway and walk, about 1,200 sq ft, $250. The crew finds orange sprinkler stains on the walk and texts a photo: "Rust stain treatment on the front walk, $75. Should lighten the stains, may not fully remove them. Reply YES to add it." The customer replies yes at 10:40 a.m. The invoice shows three lines totaling $775, notes the text approval and "Oxidation on south wall remains, as noted on the estimate," and goes out with six photos and a pay link before the crew leaves. The prices are made up for illustration.
On-site add-ons invite disputes: the customer says yes over the fence, sees a total above the estimate and remembers the conversation differently. Typical ones are rust, irrigation and oil stains, gum, gutter faces, a patio or pool deck that wasn't quoted, fences and outdoor furniture. Get each one approved in writing before you start it.
The approval message names the surface, the method, the price and any limits, with a photo of the area. For stains, put the limit in the offer itself ("should lighten, may not fully remove"), not in a note written after the result disappoints. If the customer is out, text the offer and wait for a reply; doing the work first turns an add-on into an argument.
Give each add-on its own invoice line with its approval ("Approved by text, 10:40 a.m.") and keep the message with the job. If what you find changes the job itself, such as a deck that needs a lift or growth that needs a different method, stop and price it as a change order; see how to handle change orders.
Much pressure washing happens with nobody watching: homeowners are at work, commercial crews arrive after closing and HOA managers are off site. Take photos for the invoice, not just for social media.
If a customer later reports damage, your before photos and the method on the invoice are what you'll point to. Call your insurance agent early if it could become a claim.
House washes and driveways rarely need a deposit. Ask for one when you're spending money or holding days for a specific customer: sealer or stain bought for that job, a lift rental for a three-story building, or a multi-day HOA, apartment or commercial flatwork project.
Write into your deposit terms that a weather reschedule moves the deposit to the new date. Before you set an amount, check whether your state limits up-front payments on home improvement contracts and whether its definition reaches cleaning or sealing work; how much deposit to ask for covers the rules. On the final invoice, show the deposit as a credit with its date and payment method.
Example: A paver patio clean and seal sells for $3,000, including about $900 of sealer bought for this job. A $900 deposit at booking (where your state's rules allow that amount) pays for the sealer before you order it. A wet week pushes the job back, and the deposit carries over at no charge. The final invoice shows the $3,000 total, the $900 deposit with its date and method, and $2,100 due when the sealing is done. The numbers are made up for illustration.
Management companies pay vendors through accounts payable, and an invoice from a vendor who isn't set up yet tends to sit. Send the paperwork with your first proposal and keep it current.
A Form W-9 gives the payer your legal name, tax classification and taxpayer identification number for its tax reporting. Homeowners rarely ask for one; management companies, associations and commercial clients usually will. Use the name and tax classification you file under, read the instructions closely if your business is an LLC, and sign it. Match the business name on your invoices to the W-9, or accounts payable may hold the payment. Send it securely, since it carries your taxpayer ID.
A certificate of insurance is a summary of your coverage, issued by your agent or insurer, that lists the requester as the certificate holder. Read each request before you call your agent:
Example: A management company's work order covers an association's pool deck, clubhouse walkways and mailbox kiosks, not to exceed $3,000, and your W-9 and certificate went in with the proposal. The invoice is addressed the way the manager asked (the association's legal name, in care of the management company), shows the work order number at the top and lists each area: pool deck $1,400, walkways $900, kiosks $300, for $2,600, with dated photos. When the manager asked on site about the entrance monument, you sent a separate price for approval instead of adding it. The numbers are made up for illustration.
Recurring commercial work (dumpster pads, drive-thru lanes, storefronts, fuel station pads, parking garages, fleets) should run on a written service agreement and be billed on its terms. The agreement should cover:
Because many visits happen after hours, each invoice needs proof of every visit:
Example: A restaurant group pays $150 a visit to wash the dumpster pad at three locations every week, on net 30 terms, with a PO for each location. In a four-week month, a hard freeze cancels one week at all three, and the agreement says weather skips aren't billed or made up. The monthly invoice lists each location's store number and PO, every visit's date and time window, and the skipped week as "Not serviced, freeze, not billed": 3 visits × 3 locations × $150 = $1,350, with dated photos attached. The numbers are made up for illustration.
When a commercial invoice passes its terms, follow the agreement and the reminder sequence in how to collect overdue invoices. Charge a late fee only if the agreement includes one and your state's rules allow it.
Rain, wind that would carry soft wash solution onto plants or cars, and freezing temperatures can each cancel a pressure washing day. Put your policy in writing at booking so the invoice never has to argue about it:
Planning crews and cash flow around the wet and freezing months is covered in the pressure washing seasonal playbook.
It depends on your state, so get a clear answer before you set up your invoice lines. Ask your state revenue department or a CPA whether your cleaning services are taxable, whether the answer differs for homes and commercial property, and whether add-ons such as sealing or staining are treated the same way as washing. Ask again before you take work in another state.
Go look, with the customer if you can, and compare it with your after photos. If you missed it, clean it at no charge under your re-clean terms. If it's a condition your estimate or the add-on approval already named, such as oxidation or a stain that might not lift, show them that note and offer a separately priced treatment if one would help. Either way, add the visit and its photos to the job record.
Only on terms they agreed to before the job. If you want a late-cancellation or lockout fee (a locked gate, a dog in the yard, the water shut off), put it in writing at booking, separate from your weather policy, and use the same name for it on the invoice. A fee the customer first hears about on the invoice is hard to collect and tends to cost you the customer.
