Questions Multiple companies in one tenant or multiple tenants?

Hi,

We are researching the best option regarding company structure in Acumatica.

We have a client that has 9 companies. Is there any specific benefit to managing each company in its own tenant? We have always just implemented multiple companies in a single tenant, however, then we can't use the consolidation option in Acumatica. Is it worth giving the multiple tenants a try or would you say one tenant with multiple companies works best?

The above assumes that there is only one base currency for all companies, the sharing of the chart of accounts, customers and vendors is no issue. I am purely looking into the consolidation option. 

Regards

Marine
