What does error message " select at least one way to get paid"...I've mean please?

Hi there, @Lindaam.

There are times that the data in your browser is outdated, which needs to be cleared to avoid this error. To isolate this, I suggest using an incognito browser to check if this is a browser-related issue.

Here's how you can access private browser:

• Google Chrome: Ctrl + Shift + N
• Microsoft Edge: Ctrl + Shift + P
• Firefox: Ctrl + Shift + P
• Safari: Command + Shift + N

Then, try creating the transaction again. If it woks, you can go back to your regular browser and clear it's cache. It will speed up the process next time you want to create a transaction in QuickBooks Online (QBO).

Check this article for detailed guidance in creating an invoice: Create invoices in QuickBooks Online. It'll also show you how to send customers a link over SMS or messenger service to view their invoices and how to review open invoices. 

After receiving the invoice payment, we'll have to record it to mark the invoice as paid. Refer to the following article for detailed guidance: Record invoice payments in QuickBooks Online.

I'm always here if you need further guidance in creating an invoice and or anything else by leaving a reply below. Take care and have a great rest of the day!
