ActiveCollab Retainer Viability Curve

ActiveCollab's pricing tiers create a clear threshold for agency resale. The Plus plan at $12.50/user/month (annual) caps at 3 members, making it ideal for small client teams but limiting scalability. The Pro plan at $10/user/month (annual) supports unlimited members, so per-client cost scales linearly with seats. An agency packaging ActiveCollab as a managed retainer must map client team size to the right plan. For a 5-person client team, Pro costs $50/month, leaving room for a $150 retainer with a 67% margin. For a 20-person team, the cost jumps to $200/month, squeezing margins unless the retainer scales. The framework plots client team size against ActiveCollab cost to identify the break-even point where retainer pricing becomes unviable. Agencies should target clients under 15 users to maintain healthy margins, or adjust retainer tiers accordingly.
