Synchronize Inventory Across Multiple Platforms

Multichannel selling has become an integral part of the eCommerce business expansion strategy for many merchants. With the advent of the world-famous marketplaces, it is possible to increase brand visibility and enter new markets with little upfront investment.

When you are just making the first steps to multichannel selling, the road might seem bright and sunny. However, there are many pitfalls you need to be aware of and inventory management is one of them.

In this article, we uncover the main challenges every multichannel seller needs to address and discuss why multichannel inventory management software should become an integral part of your daily eCommerce operations.

What is eCommerce Inventory and Why Is It Important?

Synchronize eCommerce Inventory

Inventory is the number of goods, products or services you offer to your customers. These may be raw materials, parts, and everything in between. eCommerce mostly deals with ready-to-use products that are prepared for being purchased and delivered to buyers.

Inventory is a big word for all eCommerce sellers as the lack of its management may have a negative impact on the reputation of a seller, ruin customer experience and even get you banned from the top marketplaces.

Why Inventory is Important for eCommerce

Some products have a longer shelf life while others sell out during the first days of being listed on a website or a marketplace. When sellers track inventory in a spreadsheet, there is no brainer that some products are forgotten about and they lie around for a very long time. As a merchant, you need to avoid having such situations at any cost low-in-demand inventory increases your spending on warehousing thus decreasing your revenue.

All of the above makes inventory management vital for any up and growing eCommerce business as its lack may jeopardize all your other efforts.

To get a better picture of the negative consequences that you may encounter let’s imagine a seller with 100+ SKUs who sells products on a few marketplaces like Amazon, eBay, and Walmart, and tracks inventory in a spreadsheet. Even with the high level of technology development and the availability of various inventory management tools, you would be surprised how many sellers still do everything manually.

The sellers need to constantly divide attention between these marketplaces, manually track orders and make changes in the spreadsheet. However, even it cannot guarantee that there will not be any overselling as two buyers can order the same product on Amazon and eBay, and the seller just cannot personally control the process and manually synchronize data from multiple sales channels.

As a result, you need to deal with refunds. In the case of frequently repeated occurrences, you will get negative customer feedback which directly influences product ranking. Moreover, overselling contradicts with the policy of the top marketplaces like Amazon, Walmart, Rakuten USA, etc., and they may even ban you from selling products on their platform.

The Main Benefits of the Established Inventory Management Process

Keeping track of inventory helps you estimate how products are selling and which products are not popular among your customers. Inventory management brings the following benefits to retailers:

  • Inventory management helps eCommerce companies to keep track of inventory and avoid overselling
  • Sellers can better organize products in categories
  • Items that sell well do not run out of stock as eCommerce business managers control inventory 24/7 and have time to order new batches of goods
  • Inventory management clearly displays which products sell well during specific time periods and which are better suited for other times or even sales channels
  • Keeping track of inventory increases product visibility for online merchants
  • Data is quickly synchronized across all sales channels.

Inventory is what helps companies track their performance at the end of each accounting period, determine which products sell well and which they should not sell in the future. With the help of inventory data, it is easy to make data-driven decisions regarding your stock and promotion activities.
