In Stamps.com my presets had a " Message field". There I could write * (item quantity) Thank you* it would print out ON the label for that preset so packaging would be much easier. Without that packaging has to determine quantity to package according to weight.
ALSO in the Stamps.com presets I could customize an international quantity preset to have the correct customs form filled out for quantity ordered. In ShipStation I filled out my preset customs form for 1 unit ordered and when I printed an order for 2 units ordered, I see the automated customs only said pkg had 1 unit in there. PRESETS need to be more like Stamps.com for ease of use! Thank you!
