Database for customers

Hello

I would love the ability to have a database of our customers with some custom fields i.e. Customer No: to uniquely identify them so that I can link projects in Asana.

The main reasons for this are as follows:

Be able to search and report on projects for that customer.
Be able to link the data via API to another cloud serves ie. Zendesk for some workflow/produces and reporting.

Regards
Neill
