Basecamp Flat-Fee Client Fit Matrix

Basecamp's pricing splits on two variables agencies usually conflate: user count and active project count. Pro Unlimited at $299/month flat removes per-seat math entirely, so a retainer with 30 client stakeholders costs the same as one with 3. Pro at $79/month caps at 10 users and 8 active projects, and Freelancer at $29/month holds 5 users and 3 projects. The matrix: plot each client retainer by headcount and concurrent projects. Retainers with many invited client users but few live projects belong on Pro Unlimited, where free client and contractor seats stop inflating cost. Retainers with 3 or fewer projects and a small internal team sit comfortably on Freelancer. Agencies running several small retainers on Pro risk paying $79 per workspace when $29 covers the same 3 projects, so audit project counts quarterly before renewal.
