Most merchants can deliver the majority of orders within a few days. For these merchants, a combined authorization and capture is a huge time-saver. They no longer have to do the capture/invoicing for each order manually.
So, please offer an ‘auto-capture’ option in your backoffice and/or plugins. That way, capture is done automatically, right after authorization.
Please do make sure the order- and invoicenumber of the merchant are used for authorization and capture.
