When using cash basis what accounts are debited and credited when I create an invoice?

Oh, I see.  It debits A/R and credits Sales Revenue - which means this invoice is actually created on an Accrual Basis, not a cash basis.  Quickbooks screws us again!

The difference between Cash and Accrual is report-based and beneath it all, QuickBooks is an accrual set of books. The fact that you wish to issue a customer an invoice for them to pay later technically is an accrual action and in theory makes you accrual rather than cash. Same goes if you enter a vendor bill to pay later - this is an accrual transaction and "pure" cash basis accounting does not allow for either invoices or bills. What you are doing, as most of us do, is use am IRS approved HYBRID accounting system and they are fine with it as long as we are consistent.

Rest assured, however, that your Cash Basis reports will be correct in the fact that on a cash basis your income ONLY posts when your customers pay, and your expenses ONLY post when you cut a check. It works as it should and we are not "screwed" in the process

And even though an Invoice credits Sales Revenue if you run a cash basis P&L the unpaid Invoice will NOT be included in income. Try it. Run P&L and then toggle back and forth between Accrual and Cash and you will see the difference.

In recording transactions there is no difference in how you record it, only how you report it. And since a customer payment is only a payment - only cash flow and never income - there has to be a debit first to A/R from the invoice. On cash basis A/R cancels out Sales Revenue
