Go to Settings → Integrations → Stripe.
Click Connect. A secure Stripe window opens to start onboarding.
In Stripe, enter/verify your business details, add a bank account, and enable charges & payouts.
When Stripe redirects you back, confirm your Stripe Account ID shows and there are no “Incomplete” notices.
You’re done—online payment links will now appear on invoices you create (and in any unpaid invoices you resend).
(Optional) Open Stripe Payment Settings on the same page to choose how you handle processing fees.
Go to Settings → Integrations → Stripe.
Click Disconnect.
Confirm in the prompt: disconnecting removes online payment options from invoices. (Existing unpaid invoices will no longer be payable via Stripe.)
You can reconnect anytime by clicking Connect again and completing Stripe’s flow.
