You asked Hi, using the simple start application how do you record a personal expense that has nothing to do with my business income and expenses please?

Welcome to the Community, @doubleawindowcle.

Recording personal expenses affect your business records. Though, we encourage QuickBooks users not to mix personal expenses to your business. However, I can walk you through on how to record it properly in your QuickBooks Online.

Here's how:

1. Click the + New button, then select Expense or Cheque.
2. Choose the payee from the drop-down.
3. Select the appropriate bank account you used in the Payment account drop-down.
4. In the Category details section, choose the category of the purchase.
5. Enter the necessary information and the amount.
6. Click Save and close.

After recording the personal expense, you can reimburse the company when you're ready. For more guidance, feel free to check out this article: Pay for personal expenses from a business credit card or bank account.

To learn more about mixing business and personal funds, you can read this article for detailed information: Mixing business and personal funds.

Please let me know if you need clarification about this, or there's anything else I can do for you. I'll be standing by for your response. Have a great day and keep safe.
