Can I use Craftybase for more than one business?

Using Craftybase for multiple businesses is going to depend on your particular situation.

If you file only one tax return for your businesses --  for example, maybe you have multiple Etsy shops set up selling from the same inventory, and just using different names.  Come tax time, you file using just one return for all of it.  This is a situation where it is okay to use Craftybase for your businesses.

If you file multiple tax returns for the businesses in question, then it is not okay to use one Craftybase account for all of them.  Craftybase does all of its reporting for one entity only. 

The exception to this would be if you are only using Craftybase to keep track of your inventory, and don't use it at all for your taxes or reporting.
