A PSA (Professional Services Automation) manages the business side of an MSP: tickets, time, contracts, billing, and reporting. An RMM (Remote Monitoring and Management) manages the technical side: monitoring endpoints, deploying patches, running scripts, and providing remote access. Both are required for a managed service practice — they are complementary tools, not alternatives.
The PSA is where your business lives. Tickets flow in, time gets logged, agreements generate invoices, and reports measure profitability. The RMM is where your technical operations live. Alerts fire when a device is offline or a disk is filling up, patches deploy on schedule, and techs remote in to diagnose issues. In a typical workflow, an RMM alert creates a PSA ticket automatically, a technician logs time against that ticket in the PSA, and the time rolls up to the client's monthly utilization report. The two systems must talk to each other — most PSA and RMM vendors offer native or API-based integration. Some platforms (SuperOps, Atera, Syncro) combine PSA and RMM functionality in a single tool, which reduces integration complexity but may offer less depth in each module than best-of-breed solutions.
A PSA is not a CRM, though many MSPs use it to manage prospects. An RMM is not a backup solution, though some RMMs (NinjaOne) include backup modules. Neither tool replaces a dedicated security platform — EDR and SIEM are separate categories. Running a PSA without an RMM means you're doing break-fix, not managed services.
