1. Iowa-specific invoice requirements
- Sales tax line: 6.00% state rate. Services billed to IA customers must include sales tax. Many services taxable (info, repair, transportation). Combined 6-7%.
- Late-fee cap: Iowa statute Iowa Code §535.2 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 Iowa 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 Iowa 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 Iowa
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. Iowa customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
