Rent Attribution - Multiple tenants paying same amounts

[Chuck M.]

We've grown our portfolio up to 22 units and have a mix of tenant payment methods: manual cheques (fun), e-transfers, bank counter deposits and some have done PADs at their local branch.

Our challenge has become with the PADs, we don't see any information about the source account owner - our statements just show TransferXYZ to Account ABC or similar vague transaction information.

We have about ten units that all pay the same amount and thankfully only a few are on PADs but if we have one that is late - we never know who it may be until we do the dial-around.

Is there another solution out there we should be directing these tenants to be using? What are others doing in similar situation?
