My name is Rainer Bay and since 1995 I have worked professionally with Danish as well as foreign companies where I have advised users "how-to" in Dynamics NAV; today Business Central 365.

I develop and maintain using the latest tools so you can feel completely safe with me on board

I have always felt respected for my work and I speak just as well to the warehouse worker as to the finance manager

Cloud or On Premise?
No doubt a cloud solution is future but maybe it is not for all kind of business.

It is important for you that you are aware of which version your ERP supplier installs for you; it is always best to use the latest version. If you choose a Cloud solution from Microsoft, your system will be updated automatically based on the plan that has been created.

I work with both IT Houses and end-users.

For large projects I do great company with other NAV Consultants, .NET developers and project leads.


I have many years of experience in assignments in Dynamics NAV with, among others, these industries: car repair, shops, rental, catering, retail (POS), wholesale, manufacturing, associations/clubs, insurance, iInfrastructure (Train traffic), internet service providers, consultancy, accounting, telephone companies, transport/warehouse management.

My primary competence is to programming C/Side and AL in the new technology Extensions (Apps). I have great financial understanding and have several times taught accounting understanding as well as setting up and starting a company from scratch.
