By accident, I did a PERSONAL purchase with my business credit card. Now , How can I do reconciliation with this amount?

Hi @info200,

Running your business with QuickBooks Online is an awesome way to stay on top of your bookkeeping. I know how important it is to account for business and personal expenses in QBO, and I'd be happy to shed some light on this for you. 

If you've used the Receipt Scanning tool, your expense will be uploaded with the total amount to QBO. The scanning option allows you to select only one payment account, and at this time there's no way to split the transaction using this feature. Don't worry, there's a simple workaround you can use in order to resolve this. 

All you have to do is journal entry out the personal items to the correct account. This will help you ensure all funds are being recorded correctly. You can create a journal entry by clicking + New > Journal Entry. 

Hope this helps ;)
