1. Washington-specific invoice requirements
- Sales tax line: 6.50% state rate. Services billed to WA customers must include sales tax. State 6.5%; many services taxable. Combined commonly 8.5-10.5%.
- Late-fee cap: Washington statute Wash. Rev. Code §19.52.020 caps interest on unpaid invoices at 1.5% per month. Spell out the rate in writing on every invoice and in your contract — courts won't enforce undisclosed fees.
- Right-to-cancel notice: Customers in Washington get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Cleaning Service line items + standard terms
Every cleaning service invoice in Washington should itemize work clearly. Standard cleaning services use Net 7 terms with no deposit required.
- Recurring service — billed by flat.
- Deep clean add-on — billed by itemized.
- Supplies surcharge — billed by pct.
3. Cleaning Service licensing in Washington
No specialty license in most states. Bonding and insurance required for commercial contracts and key-holder access.
4. Send and follow up
Send the invoice the same day work completes. Use software that records open events and offers a one-click online payment so you don't need to chase a check by mail. Washington customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
