Label Sizes Too Limited: We don't use 4x6 for our business and that's all Shipstation Allows
An option to customize label sizes like Stamps.com would help. I use label sizes 7 1/2 x 2 1/2 amongst other varying sizes and being forced to use a 4x6 or 8.5x11 limits our options. I wih the flexibility from Stamps.com would transfer over to ShipStation. Using ShipStation at this time would not be a good fit for my company.
