How to make the new style invoice I created the default instead of the standard invoice?

I'm here to help you make your invoice template a default, accounts.

We can change the default sales template in the Custom form styles page in QuickBooks Online. I'll show you how:

1. Go to the Gear icon and then select Custom form styles.
2. Locate the form you want to make as the default.
3. Click the drop-down menu under Edit.
4. Select Make default.

Additionally, I've added this article that'll help you gently remind customers about invoice due dates: Send Invoice Reminders Automatically or Manually.

Please fill me in if you have any other questions about customising form templates. I'll always be around to help. Keep safe!
