1. Michigan-specific invoice requirements
- Sales tax line: 6.00% state rate. Most services rendered in Michigan are exempt from sales tax — but materials, parts, and tangible goods are not. State 6%; uniform statewide. No local sales tax.
- Late-fee cap: Michigan statute Mich. Comp. Laws §438.31 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: Michigan requires a signed agreement for any job over $600. Reference the contract number on the invoice.
- Right-to-cancel notice: Customers in Michigan get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Registered Dietician line items + standard terms
Every registered dietician invoice in Michigan should itemize work clearly. Standard registered dieticians use Net 30 terms with no deposit required.
- Initial assessment — billed by flat (~$220 default).
- Follow-up session — billed by session (~$95 default).
- Meal-plan package — billed by flat.
- Insurance billing — billed by flat.
3. Registered Dietician licensing in Michigan
RD/RDN credential plus state license required in most states. Medical-nutrition-therapy CPT codes for insurance claims.
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. Michigan customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
