You guys provide good warehouse processing service. I like auto address correction, label, invoice and other template printing, CAN create own customized template
If it is available in mac and Linux(Specially Ubuntu) this will help a lot.
Support was good, they solve our technical issues.
Still need more online documentation because most of document do not cover all features that you developed. You did not mansion what is maximum length of item(product) name, supported character set(restricted special characters)
