What do you want to learn?
Preparing ecommerce inventory
Before you establish an inventory management process, you’ll first want to prepare your inventory for the unexpected. Below you’ll find information on how to better forecast future orders and customer demand, plus the different options for inventory financing.
Inventory can be a company’s most expensive asset, requiring investment before you have any sales. Inventory financing ensures continuous business growth through an asset-backed line of credit or short-term loan for purchasing more product.
If your ecommerce business is in the midst of growth (new product offerings, more sales, etc.), then you’ll highly benefit from having a plan in place for possible cash flow gaps, especially if a majority of cash is going towards production. If not, it may lead to problems with inventory accounting. A few inventory financing options include equity finance, WIP finance, AR financing, crowdsourcing, and merchant cash advances.
Inventory forecasting calculates the inventory needed to fulfill future orders. Using historical sales data and other macro-level trends, you can make smarter, more accurate predictions on what products will sell over a specific period of time. There are several benefits of inventory forecasting, including less inventory needed on hand, more sales from fewer out-of-stock items, less manual labor, and more efficient production cycle.
Managing ecommerce inventory
Effectively managing inventory is one of the most critical aspects of running a successful ecommerce business. If you don’t, you risk losing money or failing to meet customer demand. The following information provides insight on how to establish an accurate, efficient, and cost-effective inventory management process.
The inventory management process is an important aspect of ecommerce success. It refers to the management and monitoring process of a company’s stocked goods. The process includes everything from ordering and restocking your inventory to inventory forecasting. A proper inventory management process helps you prepare for the unexpected, such as running out of a product, miscalculating storage needs or space, manufacturing delays, and cash flow issues.
Inventory management software automates and streamlines the process by tracking inventory levels, orders, sales, and shipments across channels and locations. In today’s digital world, an inventory solutions system is a necessity for growing your ecommerce business.
The right inventory software will help automate several of the inventory management techniques and methods listed below, saving time and lowering the number of human errors. It is data-driven and provides real-time updates, rather than manual, one-point-in-time methods.
To ensure your ecommerce business has the right stock levels needed to fulfill orders on time, inventory control is a vital process that optimizes inventory storage. The primary goal of inventory control is to keep only the necessary units on hand without spending too much money upfront. The outcome of accurate inventory control leads to reduced costs, warehousing improvements, and satisfied customers.
When one fulfillment center isn’t enough, you may want to consider distributed inventory. Splitting your inventory across multiple fulfillment center locations is a great way to better serve your customers, especially if they’re scattered across the country or if you’re looking to provide 2-day ground shipping.
Other reasons to consider inventory distribution is if you ship a high volume of orders and/or your products or orders are heavy in weight. Many 3PLs provide multiple warehouses so you can deliver the fastest, most affordable shipping.
Order picking is the secret to a successful fulfillment process. A pick list is the customer order information that’s sent to the warehouse that indicates the items the picker will need to retrieve from storage. There are different types of picks lists, but they should all provide a recap of the items ordered and should be easy and clear to understand. A single pick list may contain a single item or several of a certain SKU. As soon as a pick list is generated, the order fulfillment process can begin.
An inventory audit is an analytical procedure that checks a company’s inventory and confirms the financial records and actual count of goods match. It helps ensure accurate stock levels and reporting, and prevents stockouts. An inventory audit can be conducted by doing a spot check (i.e., counting physical stock to see if it matches how much you believe you should have), or having a third-party auditor perform the procedure.
Inventory tracking consists of knowing which SKUs you have in your possession, the locations in which you store them, and the quantities available at each location. An inventory tracking system will help you keep track of real-time inventory levels of each SKU for better inventory control across your stores.
Accurate inventory tracking should take place throughout the entire supply chain, including tracking inventory from your supplier, returns from customers, and damaged goods. Using an inventory tracking system is the most efficient inventory tracking method as it ensures greater transparency and accuracy than other methods.
Ecommerce inventory reporting
Get smart about your inventory by having a good reporting process in place. All ecommerce businesses, small and large, must be able to report on key inventory data points to continually improve and make better business decisions. Below you’ll find resources for inventory accounting and reporting.
Inventory accounting is a process that tracks and accounts for changes in the values of inventory over time as it relates to manufacturing and costs of goods sold. When new products are purchased at a different cost than before, the inventory value will change. Inventory value will vary based on how much product you have on hand, how much you are selling, and any changes in supplier pricing. Inventory value will also change when products are damaged, expired, or outdated.
An inventory report shows the amount of inventory on hand at a given time. It displays numbers that represent product(s) you’re able to sell now, inventory you are ordering, or inventory you need for internal business use. A well-organized inventory report will you help you avoid over-ordering inventory or running out of inventory when customers buy your products online.
It can be created in physical or electronic form, but a best practice is to connect the systems that utilize your supply chain and customer order data. However, if you’re looking to create your own reports to track your inventory, get started with our free inventory report templates.
Inventory metrics and terms
Understanding all types of inventory data will help you make better business decisions as you scale. To continue your knowledge on how to best prepare, manage, and report ecommerce inventory, below you’ll find inventory metrics and important terms you’ll want to be aware of.
Carrying cost is the sum of all costs related to holding inventory including warehousing, labor, insurance, and rent, combined with the value of damaged, expired, and out-of-date products. The carrying cost of inventory will depend on your products and storage needs, your total number of SKUs, your location, your inventory turnover rate, and whether you keep retail fulfillment in-house or outsource it.
It’s impossible to predict the unexpected, especially changes in buying patterns and last-minute issues with suppliers. However, there are ways to help avoid an out-of-stock situation by understanding the inventory safety stock formula. Safety stock is extra product you keep on hand in case of an emergency or supply chain failure. It provides a safety net in your inventory to ensure you don’t run out of items.
Inventory turnover rate = cost of goods sold (COGS) / average inventory
Measuring inventory turnover can help you better manage your supply chain and sales channels effectively, as well as improve inventory forecasting. It’s the ratio that indicates how many times inventory is sold and then replaced in a specific time period.
High inventory turnover rate may indicate that you’re selling a product in a timely manner while low inventory turnover rate may indicate that certain products are not selling. Whether your inventory turnover is too high or too low, by learning how to best measure, you’ll be able to better regulate the issues as they arise.
Days on hand = (average inventory for the year / cost of goods sold) x 365
Inventory days on hand (or days of inventory on hand) measures how quickly a business uses up its inventory levels on average, and allows you to minimize stockouts. With accurate stock levels, you can ensure customers are going to be able to purchase what they need without needing to subscribe to “Back in Stock” notifications.
You can use this measurement combined with inventory forecasting to determine how quickly your products are being sold on average and accurately predict future inventory levels. In general, the fewer days of inventory on hand, the better.
Just in Time (JIT), commonly known as the Toyota Production System, is a supply chain management method designed to cut costs, increase efficiency, and decrease waste by receiving goods when they are needed. The method entails having enough inventory available to meet customer demand and the remainder is quickly stockpiled thereafter.
The JIT inventory method is most commonly used in manufacturing, but it can apply to ecommerce stores. Some advantages include reduced storage costs, improved communication, less waste, and smaller inventory investments. Some disadvantages include difficult implementation, greater risk of supply chain failure, more planning, and higher probability of stockouts.
Reorder point formula = demand during lead time + safety stock
Reorder point is the minimum unit quantity that a business should have in available inventory before they need to reorder more product. Understanding the inventory reorder point formula helps to ensure you order at the right time and don’t risk ordering too late and run out of stock. It’s done at the SKU level so you acknowledge that each product has a different sales cycle, so it’s data-driven and accurate. Solutions like ShipBob can help automatically setup reorder points to remind you it’s time to order more inventory.
Inventory shrinkage rate = (recorded inventory – actual inventory) / recorded inventory
Inventory shrinkage is when actual inventory levels are less than accounting has them recorded as. The four most common causes of inventory shrinkage include consumer theft, employee theft, inventory damage, or management errors. There are several ways to prevent inventory shrinkage.
Writing off inventory is the process of removing the cost of a portion of inventory from accounting records. This is done when inventory loses value and cannot be sold due to damage, theft, loss, or decline in market value.
