1. Indiana-specific invoice requirements

  • Sales tax line: 7.00% state rate. Most services rendered in Indiana are exempt from sales tax — but materials, parts, and tangible goods are not. State 7% uniform; very few local additions.
  • Late-fee cap: Indiana statute Ind. Code §24-4.6-1-101 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 Indiana 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 Indiana 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 Indiana

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. Indiana customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
