It may be a increase in a receivable but most accounts would argue that it isn't cash. When I help client's set up CC Clearing accounts, I set the account up in the receivable section of the balance sheet, not cash. Yes, it is an extra step but as @ThereseLogeais points out, timing is everything. I also sent up ""customers"" in AR so that clients can post the actual cash using AR cash receipts entry. Transaction JE's also work now, but in the old days, not so well.
I have thought about creating a VI to import the transactions, but no client has asked about one.
