Within the SAAS Configurator, add the ability to charge per user and a different charge per admin rather than just the monthly or annual amount for sub accounts. In addition, add the ability to charge a one-time set-up fee or a one-time set-up per user/admin.
Without to much detail, our setup requires 80% outside of GHL on a very robust product, and an excess amount of zaps and webhooks back into GHL is required, which easily justifies the cost per user/admin for a sub-account.
