The purpose of an icon is to show me a piece of information at a glance. However on various reports and billing screens the same payment icon (green dollar) is shown for all payment methods. So at a glance, I can tell it is money received, but not by which method unless I hover over the icon with a mouse. I'd rather just see the word and no icon, than have to hover with my mouse.
But if we're going to use icons, it would be better to have different icons for different payment methods so I can tell at a glance. E.g. something blue for paypal, something else for Authorize.net, CIM, stripe, bitcoin, etc. Even if it's a box with three unique letters in it.
Also, the same icon is used for Refund as for rebill payment failed.
(also coupons, but I'll make a separate request).
Thank you for this suggestion! This feature request or some aspect of the functionality suggested is currently being reviewed for possible inclusion in a future update. If there is additional information, this post will be updated to reflect it.
