Extensiv Order Management

For a mid to large company ERP system Skubana is the best we've found. It does order routing for multiple warehouses extremely well. It has some very intelligent workflows for moving inventory between warehouses and Amazon and it integrates well with Shopify, our 3PL and Amazon. It's not an inventory solution for your accounting team though without using a third-party app. It still lacks the reporting functionality needed to give us an easy to digest daily, weekly or monthly inventory view. It's still the best solution we've found and the app marketplace allows you to add on to it, easily extending its functionality.
