SPS/EDI Transaction and ERP transactions - We are paying twice?

In researching the high number of ERP transactions, we seem to be incurring, the EDI transactions are counting as ERP transactions along with the transaction cost with SPS and EDI? These significantly pump up the ERP transactions since a majority of our business is EDI based. Something as simple as updating statuses, runs the entire file every time and is counting each line as an ERP transaction. Since these Mapadoc reports tend to be suspect, sometimes this can get run multiple times per week. SO we pay for each part of the SPS transaction and add to the ERP transactions every time we run anything in SPS. Why are we paying twice since this is an Acumatica add-on and integrated - shouldn’t there be an advantage?
