The Stripe payment integration allows you to send an invoice link to a client which they then can then view and pay. It will show the product they have purchased and the amount with a Pay button which lets them securely pay through Apple Pay (on iOS devices when enabled), Google Pay (in Google Chrome and Android devices when enabled) or by credit card (all devices). Once payment is processed - this is a matter of seconds - you will receive an instant iOS notification and will find the payment in the Payment tab of the client's profile in the app.
