The best part about this shipping software was that it helped me ship my products within minutes for free! I also liked how easy they make things like tracking shipments as well as receiving them once shipped which made life much easier.
There are many other features but these two were what i used most frequently so far. Also there could be more options when sending international packages because sometimes customs can delay your items by up to 3 weeks even though you have paid all fees required beforehand in order to release those goods faster. We use SF express mainly for our domestic deliveries since we live very close together in one city where everything's just around us.
