Best ePayment / ACH service for Weekly rentals

[Rich Zellmer]

Can anyone recommend a good service for invoicing tenants for weekly vacation rentals and allowing them to pay via check.   The reason I mention that these are weekly rentals where my friend doesnt need a tenant management portal as he will have mostly one time tenants.   We were going to use quickbooks for the payments as that is what I use but for new clients hey charge a 1% fee for paying via ACH rather then a .50 fixed payment.  There is a $10 cap which wouldn't be awful if he just sent one invoice per customer but payments are often broken down in to 2 or 3 payments over the winter season so we are looking at fees that could be $20-$30 per week of rent.  Rents are high, over $7500 a week so the best solution is likely a cost not a percentage based solution. 

any ideas?
