I understand that, and to clarify, if any given member has a job that is booked and you look at the job or invoice, there isn't any way to know if a discount as actually been applied to any given line item within the admin invoice itself at the task level. The customer facing invoice simply says "discount applied = $X".
An example where this gets cumbersome: A customer has multiple estimates, then purchases a membership. Existing estimates will not apply the membership discount. The new estimates do apply the discount. If the customer had 8 different estimates, some from pre-membership, some from post membership, then moves forward with all of the estimates, the discount will not apply to old estimates.
When you convert the multiple estimates into a single job it becomes difficult to validate what line item tasks did or did not get a membership discount when the customers ask if that has been applied. This requires looking at the recently booked job's invoice, pulling up pricebook and comparing each line item task, one by one to see if the customer actually got every line item discounted.
Does that explain it well? Please call if you need me to screen share.
