We have a few pro bono accounts that we would love to give truly free to the client but our only option is to give them the account for $1/month or $10/year which is the minimum available on SaaS Plans and then give a 365 day free trial, but they still get billed after the year expires.
The main issue is, we want to have these free accounts for select clients we work with but we need to have them on SaaS Mode so we aren't also paying for their phone/email/etc usage.
