1. Maine-specific invoice requirements
- Sales tax line: 5.50% state rate. Most services rendered in Maine are exempt from sales tax — but materials, parts, and tangible goods are not. State 5.5%; uniform statewide. Lodging/meals 9%.
- Late-fee cap: Maine statute Me. Rev. Stat. tit. 9-B, §432 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 Maine get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Music Instructor line items + standard terms
Every music instructor invoice in Maine should itemize work clearly. Standard music instructors use Net 0 terms with no deposit required.
- 30-min lesson — billed by session (~$35 default).
- 60-min lesson — billed by session (~$65 default).
- Recital fee — billed by flat.
3. Music Instructor licensing in Maine
No license required for private instruction. Background check and child-safety policies expected for working with minors.
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. Maine customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
