Why Agencies Need Better Contracts
Agencies face three core risks: scope creep eating margins, IP disputes over creative work, and clients ghosting on payment. Solid contracts solve all three.
Retainer Agreement Structure
Best for ongoing work:
Project-Based Agreement Structure
Best for defined deliverables:
IP Ownership
Standard practice: agency owns work product until final payment, then assigns to client. Stock assets, fonts, and proprietary tools remain agency property. Make this explicit — many disputes arise from unclear IP transfer.
Performance-Based Contracts
Performance fees (% of revenue, leads, conversions) are increasingly common but tricky. Key issues: (1) attribution — is it really your work driving results? (2) tracking access — agency needs analytics access, (3) cap on performance fees, (4) clawback if numbers are revised.

FAQ
How much should an agency retainer be?
Industry benchmarks: small agencies $3-10K/month, mid-tier $10-50K/month, enterprise $50K+. Set retainer based on hours included × your blended hourly rate, with 20-30% margin.
Should clients own all the creative work?
Standard: client owns final approved deliverables upon payment. Agency retains rights to use in portfolio (with anonymization if client requests). Source files (PSDs, etc.) often command extra fee.
Can I include automatic price increases?
Yes. CPI-based increases (3-5% annual) are standard for retainers. Notify in writing 60 days before renewal.
