Interesting Public sector receivables issue need some advise pls
Background
We are a public transport company and lease out vanpools to users and receive money; there are a few federal users that get IRS subsidy of $ 125 in the past they used to get a subsidy of $ 230 and we used to receive transit chqs that were sent to our lockbox just like regular checks..
Situation changes
TSA/IRS now issues credit cards worth $125 and comes the problems for users that have to pay/owe more than $ 125 say $ 150 the credit card receipts are failing
Currently we are sending credit memos for the difference and is causing us immense problems as we have to manually calculate the dues of hundreds of users need some suggestion please
