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. Freelance Developer line items + standard terms
Every freelance developer invoice in Iowa should itemize work clearly. Standard freelance developers use Net 15 terms with a 25% deposit required upfront.
- Development — billed by hour (~$125 default).
- Project milestone — billed by flat.
- Third-party services — billed by passthrough.
3. Freelance Developer licensing in Iowa
No license required. W-9 / 1099 reporting standard.
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%.
