Re: nit picky accountant has probably insignificant critique of client terminology..
That is utterly confusing. I got it, at least on second reading, but I imagine many people will be utterly baffled.
This is why not many people are accountants. 
LH66 is 100% right on this, though the terms are thrown around incorrectly so much that it doesn't really matter. When someone says "I'll credit your account for this return", everyone knows that they are getting money back, even though the terminology says it should technically be the seller saying they will debit the person's account.
