For some reason, shipstation can't figure out what to charge so they bill you later with adjustments. As a business, it's impossible to collect those charges once you've billed a customer. Twice in the last couple months I was billed adjustments. One three package shipment was adjusted 340.00 extra. The second time it was a two package shipment adjusted 194.00. I can understand a 5.00 mistake or even 10.00, but their errors are way out of line and non negotiable
