I love how quick they are to process invoices when shipping products out from China! It's not always 100% accurate but their customer service is great as well - so no issues there either!! As long time partners with gootan its been easy peasy getting orders shipped quickly without any problems at end user level once received! Would definitely recommend them if you're looking forward towards speedy shipment/invoicing solutions which helps boost your sales & grow revenue!! Great partnership thus far between us both :) I like that they have a lot of flexibility with their platform. I like that they are constantly adding new features to improve the process. I don't like that sometimes it takes a while to get paid. There were times that we had to pay twice for the same invoice. It's a great tool for companies that are looking to manufacture their own products. It's a great way to cut costs at the same time.
