ShipStation

We use ShipStation along with Shopify for shipping of our online orders. The integration is seamless and it's easy to compare shipping rates for different shipping partners like USPS, FedEx, UPS, etc. to find the most economical option or quickest delivery time. The labels are easy to print and the tracking numbers are helpful when we need to follow a package thru the delivery system. Even adding more postage to our online account is a breeze. If I could suggest anything, it would be to offer a subscription level between the 50 and 500 shipments per month level as we often exceed 50, but don't come anywhere near 500 per month.
