1. Massachusetts-specific invoice requirements
- Sales tax line: 6.25% state rate. Most services rendered in Massachusetts are exempt from sales tax — but materials, parts, and tangible goods are not. State 6.25%; uniform statewide. No local sales tax.
- Late-fee cap: Massachusetts statute Mass. Gen. Laws ch. 271, §49 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.
- Written contract required: Massachusetts requires a signed agreement for any job over $1,000. Reference the contract number on the invoice.
- Right-to-cancel notice: Customers in Massachusetts get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Locksmith line items + standard terms
Every locksmith invoice in Massachusetts should itemize work clearly. Standard locksmiths use Net 0 terms with no deposit required.
- Service call — billed by flat (~$75 default).
- Labor — billed by hour (~$95 default).

3. Locksmith licensing in Massachusetts
Licensed in 15+ states (TX, CA, NJ, etc.). FBI background check required for licensing in most.
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. Massachusetts customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
