Should you build or buy Agency Management System (Creative/Marketing Agency Ops)?
Agency management systems handle the operational core of creative and marketing agencies — project intake, time tracking, resource scheduling, billing, and profitability reporting in one place. They're built around the agency's rate card and client billing structure, with the goal of connecting project delivery to financial performance without requiring agencies to stitch together separate tools.

Check the tier and capabilities your agency actually uses. A purchased system may cover the financial and coordination core while internal tools handle intake, scoping, approvals, and reporting. Compare complete operating costs before replacing the core.
Build it, buy it, or bridge?
When building makes sense
Consider an internal build for intake, scoping, approvals, or margin reporting around existing agency tools. Familiar components make a prototype plausible. The research did not identify a named agency operating a complete self-built PSA as evidence for routine replacement.
When buying makes sense
Buying earns its keep when you need project coordination, time records, billing, accounting integration, and access controls. Compare the vendor’s coverage with the staff, integrations, and controls an internal option would need. Custom extensions can remain useful without replacing the core.

Is agency management software different from general project management tools?

Generic project tools track tasks; agency management tracks margin.
