Same issue like DirtBaggies. We shipped 870 units to Shipwire, after 68 units fulfilled, the inventory shows only 432 units left. There was about 400 units lost in the warehouse for no reason. Customer service is slow (Joel Kemp was our representative), usually responses in about 2+ days and keep telling that the inventory currently is accurate without any proof.
Owning 3 businesses but this time I got screwed from start-up with Shipwire (1st time working with them). Orders was put on hold due to insufficient stock (which is obviously not). Our customer keep emailing us because they think they got scammed. Got another email from customer report that they receive double what she ordered. We believe most of orders was doubled due to Shipwire inventory issue. We have to take the website down after 2 days of Grand Opening - what's a shame.
Will researching on competitor to see if there is any better service out there.
We will update the process that Shipwire do to fix the problem. You guys are welcome to visit our website and contact us regarding using fulfillment service we are more than happy to share our experience.
PS: Sound like a feedback from competitor but it is from a stressful business owner. We are no way get paid or get any benefit of leaving this feedback.
Update August 26, 2015: We got the problem resolved and get refund for all the item lost. They offer me a free project to cycle count the inventory to get an accurate inventory. We still lost sale because it take about 3-4 weeks to resolve the problem while we still paying the warehouse fees.
Please aware the deposit of $1.25 / item if you send large quantity of inventory (about 500 items) so it will cost you more up-front. AND Not all of orders are not ship same day.
