How to Get Paid the Same Day the Siding Is Dry

Cash flow kills more wash companies than bad tips. You can be booked solid and still scrape fuel if invoices go out after the homeowner has already forgotten the wet siding. Good house-wash invoicing is simple: bill what was done, before you leave the lot, with a payment path they will actually use.

This guide covers why exterior cleaning collections are different from a weekly mow, how to invoice from completed work, deposits, Regular vs Cash, and what to do when nobody is home. Pair it with quoting from the driveway and pricing siding and concrete.

Why house-wash collections go cold

A weekly mow trains the customer to expect a bill. A house wash is often a one-off. By Saturday they are thinking about something else. By next Wednesday your text looks like a stranger asking for money.

Other leaks:

• Quote lived in a text. Invoice is a different number.
• Driveway was “while you’re here” and never hit the invoice
• Cash in the truck, card on a Square link, check in a cupholder - three books
• They were not home. You told yourself you would bill tonight.
• Commercial AP cannot match “pressure washing $800” to a property

The fix is not a prettier PDF. The fix is tying invoices to jobs and properties you already scheduled.

Invoice from completed work, not from memory

Ideal flow:

1. Job is on the calendar for a property, copied from the accepted quote
2. You (or the helper) mark it complete and check add-ons
3. Invoice drafts from that completion
4. Customer pays by portal, card, cash, or check - recorded in one place
5. Open balances stay visible until cleared

When quoting, scheduling, and invoicing share customers, you stop retyping line items. That is the real product of invoicing connected to quotes, not another logo on a card reader.

Worked example: Thursday closeout

You finish three houses. One added a driveway. One was not home. One paid cash on the hood.

Weak closeout: You Square-link the no-show on Sunday. You forget the driveway. The cash job never hits the books. Next month you cannot tell if you made money.

Strong closeout:

1. Completions marked before leaving each lot.
2. Driveway checked on the job that added it.
3. Invoices sent from the truck - including the empty house.
4. Cash recorded on the invoice, not in a notebook.
5. One glance at open balances that night.

Three extra minutes per stop beat a weekend of reconstruction.

Dual Regular vs Cash on the invoice

If you accept cards, processing has a cost. Publish two totals:

• Cash - cash or check, no processing
• Regular - card, covers the fee

Cash and check stay free. In MowProHQ, cards are 4% + $0.30 on Free and 3.5% + $0.30 on Growth and Pro. Put both numbers on the quote and the invoice. Do not invent a third number on the driveway because they “didn’t know.”

A clean script: “Cash price is on the invoice. If you tap the card link, that’s the Regular total. Same work.”

Do not negotiate the difference away job-by-job unless you are intentionally discounting margin. Mixed policies create arguments.

Why this matters more on washes than on mows

House-wash tickets are larger. A 4% miss on a $400 wash is real money. Dual pricing keeps the cash job honest and lets card payers cover processing. Bake-it-into-one-price is allowed - then cash customers subsidize cards. Pick one policy. Print it.

Deposits: when they help, when they annoy

Take a deposit when a no-show costs a weather window you cannot refill:

• Two-story restoration with a dedicated day
• First commercial visit that blocks the crew
• Booked-out holiday weeks
• Long-distance jobs with a trip premium

Skip deposits on a standard one-story maintenance wash you can replace. Asking $100 down on every $250 rinse trains people to shop you as difficult.

Write it on the quote:

• Amount or percent
• Due at accept, not at some vague “before we come”
• Applied to the final invoice
• Forfeited or reschedule rule if they cancel inside X days / weather excepted

Card deposits hit Regular unless they pay cash. Say that too.

When the homeowner is not home

This is the default on a lot of weekday washes. Plan for it.

1. Confirm on the quote that they do not need to be present (water on, cars moved, gate unlocked, dog inside).
2. Complete the job. Photos if you use them - especially for “you missed a spot” later.
3. Send the invoice immediately with portal pay.
4. Text: “18 Cedar is done. Invoice is in your email and portal. Cash total and card total are both on it.”
5. If no pay by evening, one reminder. Next morning, one more. Then your collections ladder - not silence until next month.

The customer portal exists so they can pay without you standing in the foyer. Use it. A Square link with no property history is how people dispute a charge they do not recognize.

If they insist on leaving cash in a lockbox, still create the invoice and mark it paid. Invisible cash is how you lie to yourself about revenue.

Commercial: same-day invoice, their terms

Restaurants, lots, and managers will not tap a phone on the dumpster pad. Invoice the same day anyway.

• One invoice per property or a multi-property invoice with lines they can match
• PO or job number if they gave you one
• Net 15/30 on the quote, not invented after 40 days of silence
• Recurring pads on a route plan, not a new Square link every Friday

Same-day invoice plus net 30 still beats invoicing when you remember. AP cannot pay a job they never received.

A collections ladder that is not personal

Put this in the quote once so enforcement is policy:

House-wash customers rarely become weekly accounts. You have less leverage than a mow route. Speed at day zero is the whole game. Late fees can exist; they will not save a invoice you sent two weeks late.

Photos help collections more than they help Instagram

A clean-line photo on the property record is not marketing. It is how you answer “you missed a spot” without driving back for free. It is also how a not-home customer recognizes the charge on the portal. One after shot of the worst wall and one of the driveway if you washed it. Store them on the job, not in a camera roll you will never search.

Residential one-offs argue from memory. Your photos are the memory.

Add-ons cannot be a memory test

Patio, walk, extra stall, “can you hit the AC condenser pad.” If it happened, it is on the completion. If it is on the completion, it is on the invoice.

Train yourself (and any helper) that “complete” is not a mood. It is a checklist: quoted lines done, extras noted, photos if needed, invoice sent.

Missing add-ons are unpaid labor. Fake add-ons are how you lose reviews. Completions are the audit trail.

Metrics worth a Friday glance

You do not need a finance department. You need to see unbilled work before payroll.

Mistakes that create unpaid washes

• Invoicing from memory on Sunday
• A Square link that does not match the quote
• Hiding the card total until they tap pay
• No invoice because they “said they’d Venmo later”
• Commercial billed as one vague line
• Letting not-home jobs wait until you feel like paperwork
• Recording cash in the truck and nowhere else

Venmo later is not a policy. It is a wish.

How MowProHQ helps you collect

MowProHQ invoices from the same customer, property, and quote you already used. Regular vs Cash dual pricing sits on the quote and the invoice. Cash and check stay free. The customer portal is on Free so a not-home wash can still pay. Two seats, scheduling, CRM, quotes, invoices, and a website editor are included.

Growth is $39/mo for unlimited seats, live site and lead inbox, dispatch, GPS, and timeclock, with cards at 3.5% + $0.30 versus 4% + $0.30 on Free. Pro is $89/mo. Phone is $19/mo. AI receptionist is $29/mo.

Start free. Send the invoice before you coil the hose. Work done should be money in motion, not a reminder you will write when you get home.

Frequently asked questions

How do I get paid the same day after a house wash?

Invoice from the completed job before you leave the lot, include Regular vs Cash totals and a payment path, and collect cash, check, or card while the siding still looks like you were there. Sunday invoicing is how balances age into awkward texts.

What should a house wash invoice include?

Customer and property address, service date, line items that match the quote (house, driveway, extras), Regular vs Cash totals if you dual-price, and a simple way to pay. If they were not home, the invoice still has to stand on its own in a text or portal.

Should I take a deposit on house washing?

Deposits help on two-story restorations, commercial first visits, and booked-out weeks when a no-show costs a weather window. For a standard maintenance wash, same-day collection at completion is usually enough. Write the deposit rule on the quote so it is not a surprise.

How do I collect if the homeowner is not home?

Send the invoice and pay link as soon as you complete the job. Use the customer portal, not a Square link with no job history. Follow up that evening, then the next morning. Do not wait until the weekend. They have already stopped thinking about the siding.

Is dual cash and card pricing allowed on invoices?

Many operators publish a Cash price and a Regular card price that covers processing. Cash and check stay free. Put the same language on quotes and invoices so payment method never becomes a dispute after the wash.

Why do driveway add-ons get missed on invoices?

Add-ons happen on site and never reach billing when completion and invoicing are disconnected. Mark extras at completion and draft the invoice from that job so the patio you washed cannot vanish.

How should I handle commercial accounts that pay in 30 days?

Invoice the same day anyway, with property-level lines their AP can match. Put net terms on the quote. Recurring pads should sit on a plan, not a pile of one-off links. Same-day invoice plus their terms is still faster than invoicing when you remember.
