How do I create an invoice for a person whose already entered in under expenses? It won't let me create an invoice for this person because I already have them under expe

Hi there,

Welcome to the Community! QuickBooks Online makes it easy to create an invoice and I'll be happy to show you how. 

Step 1: Create and send an invoice

1. Select + New and then Invoice or Send invoice.
2. From the Customer ▼ dropdown, select a customer. Make sure all of their info is correct, especially their email address.
3. Review the Invoice date. Then from the Terms ▼ dropdown, select the due date. Tip: Net refers to the number of days until the payment is due. The default is 30 days, but you can change the due date if needed.
4. From the Product/Service column, select a product or service. You can also select +Add new to create a new product or service right from the invoice.
5. Enter a quantity, rate and change amount if needed.
6. Select a tax rate.

   Note: If you see the Flat rate, By hour, or By item options, this means you're in Business view. Your experience is slightly different. Select Flat rate or By hour for services or By item for products. Then enter the quantity and amount.

7. When you're ready to send the invoice, select Save and send. Or, if you're using QuickBooks EasyStart, select Send.

If you want to send the invoice later, select Save and close or Record if you’re using QuickBooks EasyStart.
