Hello, Mike Wilkes. Thanks for reaching out to the Community.
If your QuickBooks Online company was created through an Accountant (QBOA) subscription, there's a couple discounts which are automatically applied. The ones which can presently be obtained this way are promotional pricing for Wholesale Billing and ProAdvsior offers.
Currently, there's no discounts specifically for subscribers who are members of the American Massage Therapy Association (AMTA) or California Massage Therapy Council (CAMTC).
