Their customer service team are super friendly, knowledgeable & efficient! They helped us with our inventory management issues when we were using their system as well (we had to move away). Nothing really - they have been great so far though!! Great price point too compared other services out there in this space that charge more than double what you get from them now :) We use speed commerce's warehouse automation software which helps manage incoming orders into warehouses/fulfillment centers across multiple locations at once ensuring timely shipments while reducing errors along way through processing steps such as picking / packing etc.
