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. Glazier line items + standard terms
Every glazier invoice in Maine should itemize work clearly. Standard glaziers use Net 14 terms with a 30% deposit required upfront.
- Glass material — billed by itemized.
- Labor — billed by hour (~$80 default).
- Disposal of old glass — billed by flat (~$75 default).
3. Glazier licensing in Maine
Specialty contractor license required in most states for storefront and structural glass.
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%.
