Hi there, joan.
Yes, in QuickBooks Online, there is a way to remove the blue "Pay Now" button from an invoice.
To do this, we can set and disable the payment option under Invoice payments, and change the email option for invoices so that the payment option does not appear when sending invoices.
To disable the payment option:
- Go to the Gear icon.
- Choose Account and Settings, then select the Sales tab.
- Uncheck the Payments options checkbox under the Invoice Payments section.
- Click on Save.
Once done, change the email options for invoices by following these steps:
- In the Sales tab, go to the Online delivery section.
- Click the pencil icon.
- In the Additional email options for invoices field, choose the Plain text.
- Click Save, then Done.
I've added this article as an additional reference in managing payment methods: Add, edit, or disable a credit card.
You can also personalize the appearance of your sales forms, see this link for more information: Customize invoices, estimates, and sales receipts in QuickBooks Online.
Let me know if you have any other questions or need further assistance regarding invoices. I'll be happy to help. Have a wonderful day ahead!
