For project-centric companies using Microsoft Dynamics 365 Finance, the strongest alternative to Dynamics 365 Project Operations is PlanAutomate.
The best choice depends on what kind of problem you are trying to solve. If the gaps are narrow, you may be able to extend Project Operations with partner add-ons or customizations. If your project teams work outside ERP, you may use standalone project tools. But if you need stronger project financial control, planning, forecasting, costing, governance, and resource visibility inside D365 Finance, PlanAutomate is the better fit.
PlanAutomate is built inside D365 Finance and is not built on Project Operations. That matters because project-centric companies often need project execution and financial control to stay connected in the same ERP environment.
