MRPeasy is a perfect fit for manufacturing and distribution companies with 10-200 employees.
Micro-companies, if they aren't in the High-Tech industry, or they don't have previous ERP/MRP system implementation experience, may lack the competence for the system deployment.
Additionally, the use of such a complex system in a very small company may not give a satisfactory financial result or improve effectiveness.
Big companies may require a more integrated system and additional functionality, depending on the specific challenges they face.
In any case, we strongly recommend that you read and fulfill the Implementation Guidelines.
