AgencyStack
Software cost tracking built for small marketing agencies
“Valid idea with a clear wedge. Generic subscription trackers ignore client margin allocation, while enterprise spend tools charge enterprise fees. Small agencies leak hundreds monthly in unallocated software fees.”
AgencyStack sits between B2C subscription monitors and enterprise procurement suites like Cledara. It focuses specifically on client-allocated SaaS margins, multi-seat renewal alerts, and card aggregation for 5 to 40 person agencies.
Tool sprawl in agency tech stacks continues to accelerate in 2026, while popular project management tools still lack native software financial tracking.
