How can I issue a refund on a paid invoice?

Issuing a refund for an Invoice that has been paid will depend on how the client paid the Invoice. 

If your client paid the Invoice using their credit or debit card, the payment was processed through Stripe. In this case, the refund would need to be issued through your Stripe account.

If you have any questions about the processing of this refund please contact Stripe support directly.

If your client paid via a direct transfer (ACH bank transfer, Wire transfer, Found-to-Found transfer) into your Found account you can send them back a payment from your Found account. In your Found account, you can click the ‘Send Money’ option and select ‘Pay a person or business’ to send an ACH bank transfer payment out of your Found account back to the client. 

If your client paid via one of the payment apps (Cash App / Paypal / Venmo / Zelle), and if you never transferred the funds to Found, you could send a payment back to the client directly from the payment app where you received the funds.
