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. Translator line items + standard terms
Every translator invoice in Washington should itemize work clearly. Standard translators use Net 30 terms with no deposit required.
- Per-word translation — billed by word (~$0.18 default).
- Editing / proofreading — billed by word (~$0.06 default).
- Certified translation — billed by flat.
- Rush fee — billed by pct.
3. Translator licensing in Washington
Court and USCIS work requires certified or sworn translator status (varies by jurisdiction). ATA certification widely recognized.
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%.
