1. Colorado-specific invoice requirements
- Sales tax line: 2.90% state rate. Most services rendered in Colorado are exempt from sales tax — but materials, parts, and tangible goods are not. State 2.9%; home-rule cities add their own (combined commonly 7-10%).
- Late-fee cap: Colorado statute Colo. Rev. Stat. §5-12-101 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 Colorado get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. General Contractor line items + standard terms
Every general contractor invoice in Colorado should itemize work clearly. Standard general contractors use Net 30 terms with a 25% deposit required upfront.
- Mobilization — billed by flat.
- Labor — billed by hour (~$85 default).
- Materials — billed by itemized.
- Subcontractor markup — billed by percent.
3. General Contractor licensing in Colorado
Most states require a general contractor license over a job-value threshold (varies $500-$50K). Bonding and insurance commonly required.
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. Colorado customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
