We make payments by card as easy as possible for your customers.
You just need to create and send an invoice. You can do this from the "Overview" page by clicking "Get Paid" and then selecting "Send Invoice", or by clicking a specific contact in your contact database and selecting "Get paid by..."
While creating the invoice, you will have the option to enable "Accept payment via card," and this is turned on by default.
When your customer receives an invoice and opens it online, the option to pay by card will be available.
