RCM platforms should not try to build every workflow on day one.
There are mature vendors for many parts of the revenue cycle. Eligibility, prior authorization, claim scrubbing, clearinghouse submission, payment posting, denial tools, and patient engagement all have existing products. The opportunity is not always to replace them. Often, the opportunity is to orchestrate them.
Buy when the workflow is mature
If a workflow is standardized, compliance-heavy, payer-integrated, and already served by strong vendors, buying can be the fastest path.
The platform still needs to own the operating data that comes back from the vendor.
Build when the workflow creates proprietary advantage
Build when the workflow depends on platform-specific data, internal process knowledge, acquisition strategy, or a unique operating model.
Examples might include portfolio benchmarking, acquisition onboarding, workflow routing logic, or executive operating dashboards.
Integrate when the data matters most
Sometimes the right answer is not buy or build. It is integrate well.
If the vendor handles the workflow but the platform needs visibility, the integration should capture status, outcomes, exceptions, turnaround time, and reason codes in the common data model.
Centralize when variation is the problem
If every company handles the same workflow differently, centralization may create leverage. But centralization works best after the platform understands the current data and process variation.
The rule of thumb
Own the data layer. Be flexible about the workflow layer.
That lets the platform buy where vendors are strong, build where it has an edge, and switch later without losing the operating memory of the portfolio.
