1. Idaho-specific invoice requirements
- Sales tax line: 6.00% state rate. Most services rendered in Idaho are exempt from sales tax — but materials, parts, and tangible goods are not. State 6%; very few local sales taxes (resort cities only).
- Late-fee cap: Idaho statute Idaho Code §28-22-104 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 Idaho get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Mobile App Developer line items + standard terms
Every mobile app developer invoice in Idaho should itemize work clearly. Standard mobile app developers use Net 30 terms with a 33% deposit required upfront.
- Sprint / milestone — billed by flat.
- Hourly — billed by hour (~$165 default).
- App Store submission — billed by flat.
- Maintenance retainer — billed by flat.
3. Mobile App Developer licensing in Idaho
No license required. App Store and Play Store policies must be honored.
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. Idaho customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
