I really like that they have some great features for managing orders (shipping labels etc.) as well shipping notifications with tracking numbers! Sometimes it takes awhile to load up but once its loaded there is nothing wrong about this software at all!! It's not something you need right away so if your looking into cart solutions try out several before making yours decision because sometimes their are better options available now than what was offered 4 years ago - however we did endup going ahead w/Smart Cart since our needs were met in many ways by them compared other providers which didn't meet ours either price or feature wise.- Shipping notification emails & invoices sent from customers via snail mail when packages arrive rather then emailing customer only after package arrives thus causing loss of sales revenue while waiting 2 days between each alert vs being able too send same.
