how many workspaces are allowed for a business class account?

OK. thank you @Laura Holton _ACE Manchester_ .
but I would like to understand it a little better.
so can i have only one businessclass payment and with that account create multiple workspaces?

No worries at all, so when you’re considering purchasing Trello Business Class the upgrade happens per-Workspace, rather than per-individual-account, which is why Trello suggest trying to organise your boards and members into a single Workspace. 

Business Class provides lots of additional features, such as integrations with other services, collections, and a host of features to make it easier to manage your Workspace.

If you do need to maintain several Workspaces for your company, you may be interested in Trello’s Enterprise plan.

OK. ok, thanks @Laura Holton _ACE Manchester_.

you clarified a doubt that I had. This information is not clearly explained in the documentation.

I completely understand, there can be so much information sometimes it’s hard to get down to the direct answer you seek - that’s why we’re here to help 😃

Anything else you’d like to know at any point just drop us a question and we’ll get on the case!

I also had this question @Laura Holton _ACE Manchester_ and it was not clearly explained.. also kind of disappointed in this. Why can't we just call the entire business class account a "workspace" and allow them to create various teams? It would make a lot of our lives much easier where we want certain content hidden for one part of our team and others available for the whole team. Why force us to pay double for a new workspace when you allow unlimited free workspaces anyways? Seems more of a hindrance to your users than it is skin off your nose.
