If you want to discount the tenant for ACH fees:
1) Go to the property tab, sub tab - tenants
2) Click on tenant name
3) Adjust rent price lower for the ACH fee discount, then save changes
The fee will still be charged to the tenant but you have reduced the rent price.
In this way the net amount the tenant pays is without fee.
This step provides for the fee to be paid by landlord.
Note: This must be done 24 hours before any payment is made.
