From your Dashboard go to Settings and click on Invoicing Settings under Client Billing.

In the pop-up window, you will see the invoice template. Scroll down until you find a Payment Details box. Click on the little pen icon to edit and there you should write something like "Click either of the following links to pay with Venmo or PayPal: www.link1.com, www.link2.com". When done with updating click on the Save button. You can also list your bank transfer details there.

If you need a wildcard for Venmo, use this one in the Payment Details Box: {{invoice.venmo_link}}

For Zelle payments, simply add your phone number or email address associated with your Zelle account to the Payment Details or on the "Custom Payment Message" (more details below).

In the first section, you can add a Paypal link, a Venmo username, or a custom payment link

These links will be displayed to your customers next to the invoice when they receive them

In the next section, you can add a Custom Payment Message. This is useful when you want to send an ACH routing number or a Zelle email to your customer, for example

Note that this option takes precedence over Paypal, Venmo, and Custom Links (above); so if you want those links to be displayed instead, you need to leave this section blank

When you are done with all the changes do not forget to click on the Save Changes button.
