What is multichannel inventory management?

Multichannel inventory management is the process of keeping track of inventory from different sales sources and storage locations. This includes inventory for ecommerce, retail, marketplace and wholesale. With multichannel inventory management, your company can easily oversee stock levels, reorders, and inventory forecasting, so you can accurately plan for inventory turnover every quarter.

Multichannel management solutions allow you to focus on the growth of your business, rather than spending excess time and money tackling the ins and outs of your inventory.

“Extensiv just made it easy to scale. We were at a point where we could not grow at all, and then when we got on Skubana, we went and doubled the company without any pain. We could 10X from here and still keep scaling, and it wouldn't be stressful.”

How does Extensiv Order Manager work with Fulfillment by Amazon (FBA) and Walmart Fulfillment Services (WFA)?

Extensiv Order Manager works in tandem with these ecommerce platforms to provide your company with the most intuitive and customizable order and inventory management software available.

Amazon inventory management with Extensiv Order Manager lets users automatically update their inventory each time a product is sold or returned, removing virtually all the manual work and potential for errors. With Extensiv Order Manager for Amazon, you can easily track your inventory, orders, and deliveries originating from all your Amazon sales channels.

Using WFS, retailers can store all their inventory within the Walmart fulfillment network. Send your inventory to Walmart fulfillment centers to handle storage and orders, then manage WFS inventory, forecasting, and replenishment from Extensiv Order Manager.

Does Extensiv Order Manager help manage bundles and kits?

Extensiv Order Manager can easily help you combine individual products into compelling bundles, while maintaining control over the individual SKUs. Product bundling and kitting is truly a win-win since it gives you the ability to lower your pricing, while also making your offers more compelling than your competitors’ offerings. When done well, bundles can drive sales, increase optimization, and support customer satisfaction at the same time.

How quickly can a business implement Extensiv Order Manager?

90% of customers complete OMS implementation within four to six weeks—and many companies finish faster. This is incredibly fast when compared with typical software implementations, meaning you’ll see a much faster ROI than with competitive solutions. With Extensiv Order Manager in place, you can automate your most time-consuming tasks and customize the features and integrations that best suit your needs.

What makes Extensiv Order Manager reporting the best one in the market?

Our order management reporting is top-of-the-line, thanks to its native, holistic view of First In, First Out (FIFO) costs, sales orders, and shipping fees. We deliver a multitude of pertinent reports, including inventory value, inventory aging, SKU profitability, and demand planning. In addition, Extensiv Order Manager also offers an exhaustive Cost of Goods Sold (COGS) history per purchase order, which makes retroactive reviews of purchasing much more accessible for quarterly and year-end reporting.

What are the benefits of order management?

Order management and order routing are fundamental to modern, adaptable fulfillment strategies. Extensiv Order Manager allows brands to build sophisticated order manipulation rules to translate between the needs of a sales channel and those of a fulfillment provider. Additionally, order management provides order handling capabilities like order splitting, where a single order may be fulfilled by more than one warehouse. Simple order routing provides capabilities like the ability to send an order to the closest warehouse, to minimize shipping times and costs.

What else should I look for in an OMS like Extensiv Order Manager?

Beyond order routing and customer service capabilities, a modern OMS will also offer inventory forecasting capabilities. This uses sophisticated algorithms to predict sales velocity, based on historical sales and other intelligence, and ensure products are reordered before you risk a stockout. We believe order management software should serve the needs of executives like CEOs, COOs, and Directors of Operations, as well as streamline customer service.

Shipping our packages is a headache, and ShipStation doesn’t offer everything we need. Is Extensiv Order Manager a better fit?

Yes! ShipStation was built for simple businesses selling from a single channel and fulfilling from a single node, which is best for brands that are just getting started. As soon as a brand starts selling on multiple channels or fulfilling from more than one node, they should be looking for enterprise-class solutions that can handle the complexities of today while setting your brand up for the growth of tomorrow.
