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

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
