1. Denver-specific tax handling
- State sales tax: 2.9%. Local jurisdictions in Denver may add their own rate — verify with your local tax assessor.
- Late fees: CO statute Colo. Rev. Stat. §5-12-101 caps interest on unpaid invoices at 1.5% per month.
2. Standard freelance developer line items
- Development — billed by hour (~$125 default).
- Project milestone — billed by flat.
- Third-party services — billed by passthrough.
3. Payment terms that work in Denver
Net 15 is standard for freelance developers. Most freelance developers in competitive markets like Denver require a 25% deposit upfront before scheduling work. Accept card and ACH on the invoice itself — Denver customers expect a one-click payment link in their inbox.
4. Licensing & disclosures
No license required. W-9 / 1099 reporting standard.
