How to create an invoice?

I'd be glad to provide the steps you need, veenaprodec_iamt.

There are two options where you can create an invoice in QuickBooks Online. The first one is by going to + New > Customers and selecting Invoice.

For the second steps, here's how:

1. On the left panel, select Sales > Invoices
2. Select the New invoice button.
3. Add the customer's name from the Customer drop-down.
4. Choose the Invoice date, and enter the product information.
5. Hit the Save and close button.

Here's an article for more details: Create invoices in QuickBooks Online.

Once your customer paid the invoice, you will then record a receive payment. You can get the instructions here: Record invoice payments in QuickBooks Online.
