1. North Dakota-specific invoice requirements
- Sales tax line: 5.00% state rate. Most services rendered in North Dakota are exempt from sales tax — but materials, parts, and tangible goods are not. State 5%; combined typically 6-8.5%.
- Late-fee cap: North Dakota statute N.D. Cent. Code §47-14-05 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 North Dakota get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Auto Mechanic line items + standard terms
Every auto mechanic invoice in North Dakota should itemize work clearly. Standard auto mechanics use Net 0 terms with no deposit required.
- Diagnostic fee — billed by flat (~$95 default).
- Labor — billed by hour (~$120 default).
- Parts — billed by itemized.
- Shop supplies — billed by pct.
3. Auto Mechanic licensing in North Dakota
State auto repair acts (e.g., California BAR) require written estimate before repairs and itemized invoice with parts/labor breakdown.
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. North Dakota customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
