Hi cmi5,

Allow me to further assist you with the incorrect payment details showing on your invoice email. If you've used Airy New template before, we can try to check the payment details you've entered on the Airy New template if it is showing the correct one. Here's how: 

1. Go to Gear icon and select Custom form styles.
2. Select Edit on the Standard template. 
3. On Design tab, select Change up the template. 
4. Select Airy New. 
5. Click Done to save.
6. Once done, open the invoice template and then select Content. 
7. Then click on the pencil icon located on the the footer of the invoice. 
8. On Your payment details text box, enter the correct bank details. 
9. Click Done. 

Once you've enter the correct payment details on Airy New template, you can change it to the correct one by selecting the Design tab. To confirm that the changes you've made on the settings has been reflected, you can create a dummy invoice and sent it on your email. 

Let me know how it goes. Thanks.
