Hello,
I have QB Desktop for Mac. I have QB set up to track both personal and business expenses on the same P&L. I use the account types "other" to keep the personal expenses on the bottom of the P&L. I am running into trouble with a reimbursement for a credit card charge made with one of the personal credit cards. The personal credit card balance was paid with the personal checking account. Later, funds were transferred from the business checking account into the personal checking account to cover a portion of the expense, which is deductible by the company. If I categorize the transfer from the business checking as "meals and entertainment" it does not reflect on the balance of the personal checking account. If I transfer the money directly to personal checking the balance for both accounts is correct but there seems to be no way now to categorize the purchase on the P&L. 
In summary, it seems there is no way to have a reimbursement transfer between checking accounts reflect against an expense tracking account on the p&l the way I have things set up. Unless I'm missing something. 
Thanks for reading
