It sounds like you are using Zoho One. You get 40 apps for that price of $37/month paid annually. But the situation is that to get that great price, and it is fantastic, you have to put Zoho One on every computer. It's stated right in the purchase price. "Must purchase license for ALL employees*" "*Your business will have to commit to purchase Zoho One licenses for ALL employees on payroll." If the volunteers are true volunteers and not on payroll, you should be able to have only one copy. I see that they do have the Flexible-User Pricing for $90/month paid annually.
