Microsoft recently announced a new ERP system that are designed with SMB in mind. It is developed in Denmark, based on the Danish C5 ERP system and NAVISION – and the new ERP is being called Project Madeira.
This is very exciting, and I expect integration project to and from Madeira will come in the near future.
