1. Mississippi-specific invoice requirements
- Sales tax line: 7.00% state rate. Most services rendered in Mississippi are exempt from sales tax — but materials, parts, and tangible goods are not. State 7%; very few local additions. Restaurants/lodging 9-10%.
- Late-fee cap: Mississippi statute Miss. Code §75-17-1 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 Mississippi get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Plumber line items + standard terms
Every plumber invoice in Mississippi should itemize work clearly. Standard plumbers use Net 14 terms with a 30% deposit required upfront.
- Service call fee — billed by flat (~$95 default).
- Labor — billed by hour (~$110 default).
- Materials — billed by itemized.
3. Plumber licensing in Mississippi
State-licensed in most states. Master plumber license typically required for self-employment.
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. Mississippi customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
