Common Mistakes to Avoid
- 1
Working without signed contracts and scope agreements
- 2
No retainer model — project-only work creates feast/famine cycles
- 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
- 1
Form your LLC in Idaho — marketing agencies need liability protection for campaign deliverables and IP ownership disputes (filing fee: $100)
- 2
Obtain a business license in Idaho and any local municipality where your office is located
- 3
Get professional liability (E&O) insurance — typically a low-to-mid four-figure annual premium; 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
