General Business License
Colorado does not have a statewide general business license requirement. Businesses must register their entity with the Colorado Secretary of State and obtain a sales tax license from the Colorado Department of Revenue if selling taxable goods or services. Many municipalities require a local business license — Denver, Aurora, Colorado Springs, and Boulder all have their own business licensing programs with fees ranging from $25 to $500 annually.

Denver allows home occupations with restrictions on customer visits (typically 1 person at a time), no exterior display, and no storage of commercial vehicles. Colorado State law preempts local regulations that would completely prohibit home-based businesses. The Colorado Cottage Food Act specifically authorizes home-based food production with certain limitations.

Common Mistakes to Avoid
- 1
Working without signed contracts and scope agreements
- 2

- 3
Underestimating time for client revisions and communication
- 4
Too broad a service offering before establishing niche expertise
- 5
No process documentation making work dependent on founder
Next Steps to Launch Your Marketing Agency

Form your LLC in Colorado — marketing agencies need liability protection for campaign deliverables and IP ownership disputes (filing fee: $50)
- 2
Obtain a business license in Colorado and any local municipality where your office is located
- 3
Get professional liability (E&O) insurance — $800–$3,000/year; clients often require proof before signing retainer agreements
- 4
Set up agency-grade project management — Basecamp, Notion, or Monday.com for client project tracking and collaboration
- 5
Create a client onboarding process: intake questionnaire, brand audit, kickoff agenda, and 90-day plan template
- 6
Build a case study portfolio with 2-3 documented results — even pro bono work with measurable ROI builds credibility
- 7
Set up your invoicing and retainer billing system — FreshBooks or QuickBooks with automatic recurring invoices
- 8
Define your agency's core service offering and ICP — full-service generalists struggle; niche agencies (CPG brands, SaaS) grow faster
