I would highly recommend not using ShipMonk. I'm providing 2 stars because their UI is great, and the sync with Shopify is helpful so that we in theory don't have to update our inventory on a consistent basis (which in reality is not the case). If you have under 100 SKU's they may be a fit, we've been using them for a few years and everything was fine until we really starting scaling our inventory levels and SKU count. Then came receiving issues, lost inventory (and by default overselling to our customers and having to cancel orders), and sending the wrong product to our customers - as in not even inventory sold from our store (we sell dog merch, our customers have received human supplements, perfume, etc). I had to track down and reach out to the other stores separately to make sure they were aware their product (sometimes worth $100+) was being sent out to the wrong customers so they could also file claims. The lost inventory has been the biggest headache for us. When I say lost inventory I mean hundreds of units (some SKU's have a >6% shrink which ShipMonk claims is normal) that have gone missing within a few months, and no reimbursement with often what I would consider odd rational - they couldn't store everything in a single bin, therefore it's not their fault. Money drain! I will say different from other ShipMonk reviews I have mostly had good experiences with their CX team, and I think the bigger issue is that there are larger wide scale systemic issues with ShipMonk and the CX team is either not equipped to handle or they truly have no idea what happened and that's that. My negative experiences have been when agents will resolve a ticket when the issue is not fixed, so I've had to reopen tickets just to make sure they actually respond. Overall - I would keep shopping, not worth it.
