Our new small business started on 01/04/23. We have 20 startup expense transactions paid with personal CC in 2022. How should I book these given they are in last year?

Hey there, @cookiebyb-gmail-.

You can record these transactions as a regular check or expense in QuickBooks Online (QBO). Here's how:

1. Click + New and select Check or Expense.
2. Choose a Payee from the drop-down ▼ menu.
3. Select the Bank Account, Cash Account, or Credit Card you used to make the purchase.
4. In the Category details section, click the dropdown menu ▼ to select the tax category that fits your need.
5. Enter the Amount of the purchase .
6. Click Save and close.

Once done, create a bank deposit to reimburse your company:

1. From the left menu, click + New.
2. Select Bank Deposit.
3. Choose the Account to add the reimbursement to, and select the Date.
4. Go to the Add funds to this deposit section. In the Received From field, enter the person who made the personal expense, then select the account.
5. Choose the Payment Method and enter the reimbursement amount.
6. Click Save and close.

I'd also recommend reaching out to your accountant for further advice when handling these expenses in QuickBooks. They can provide you with the right guidance to keep your books accurate. 

While it is not advisable to mix personal and business funds, you may encounter situations that will require you to do so. This article will cover enough information on how to handle your business and personal expenditures in QuickBooks: Mixing business and personal funds.
