Ambitious manufacturers know that stock replenishment is one of the areas which can make a huge difference in scaling their business. For one, it can just be incredibly time-consuming to manage correctly. Thankfully, there is a way.
Suppose you’re at the coffee machine, ready for a caffeine top-up. Wouldn’t it be great if the coffee cup was always there, filled to the brim?
Well, it’s a dream most manufacturers have with their coffee as much as they do with their stock replenishment. Dreaming their stock room is always in the process of being refreshed and filled for the perfect flow of consumption.
Now, as with most things in life, there’s a good way of doing replenishment of stock, and there’s a bad way. And to make sure you’re managing your stock replenishment properly, you need to take your inventory management seriously. Otherwise, you’ll come up against stockouts and miserable customers or end up ordering too much stock and unnecessarily increasing your carrying costs.
Experts agree that extra inventory costs 18 – 35% of an item’s value for a year — a staggering number to consider. That’s why we’ve come up with this mini guide to make sure you stay on the right path to replenishing stock success.
What is stock replenishment?
Stock replenishment is the process of reordering materials to meet the demand for your manufacturing and sales orders. That means ensuring you never run out of stock and can deliver to your customers on time.
Manufacturers have been battling inventory levels with spreadsheets and stock replenishment systems for a long time. Thankfully, the dawn of inventory management software has automated many of the processes enough to allow manufacturers to give up the ancient Excel ways and focus on their products and customers instead.
It’s easy enough to say that stock replenishment is ordering stock to meet demand. But to really gain an understanding, we have to step back and see what that means in terms of the supply chain. Ultimately, your capabilities of keeping stock at optimal levels are affected by many external factors. Your suppliers are as paramount to the process as your own principles.
So yes, stock replenishment is about holding an amount of stock that doesn’t drastically increase your carrying costs while also making sure you never have stockouts. However, it also ensures you have an entire overview of your inventory, from supplier relations to purchase planning and even production scheduling.
You need to build yourself a landscape that covers all of these bases so that your inventory replenishment process becomes part of the natural order of your manufacturing business.
Now thankfully, you won’t be on your own with all this. Modern production management software can automate this for you. It makes sure that you know exactly when to purchase more materials while also ensuring you have materials available for your current manufacturing and sales orders.
But before we get to that, let’s see how we can build the foundations of inventory replenishment right off the bat.
Why is stock replenishment important?
Stock replenishment is a crucial part of any manufacturing business. It’s vital for companies that can’t afford stockouts or excess inventory. An efficient inventory management process reduces the risk of these problems and increases the chances of success.
When done correctly, stock replenishment helps improve customer satisfaction by ensuring that orders are fulfilled on time — that customers never have to wait too long for their orders.
Additionally, it keeps your inventory costs in check as you don’t need to carry large amounts of stock just to make sure you can meet demand. By having just enough supply, you will be able to reduce waste while at the same time making sure you have enough stock to meet customer demands.
What are the 3 types of replenishment?
The three main types of inventory replenishment are:
- Reorder point replenishment — This type of replenishment uses a predetermined reorder point based on past sales or forecasts. When the stock level reaches the reorder point, an order is placed with the supplier for additional stock
- Demand replenishment — This replenishment method is based on current and future customer demand. With this method, you only order enough to fill the forecasted demand. It is still essential to have some safety stock
- Periodic replenishment — This type of replenishment occurs when a certain amount of stock is ordered at predetermined intervals, such as weekly, monthly, or quarterly. This method works best for businesses that use seasonal demand cycles and need to adjust their stock levels accordingly
Understanding these different types of replenishment can help you pick out the most suitable strategy for your business, helping you save time, money, and resources.
With the right replenishment method in place, you can be sure that your business is always well stocked with just enough materials to meet customer demands. Proper stock replenishment is essential for any successful manufacturing business — it’s the key to staying competitive in today’s market.
Methods of stock replenishment
So we know that there are plenty of stock replenishment methods to follow, which is why we have decided to break it down into the main building blocks. These methods of stock replenishment are not necessarily in order of importance, but here is what it boils down to:
Covering these bases will give you a complete outline of when you need to replenish stock.
1. Setting safety stock
Stockouts are not always the most predictable crisis for your manufacturing business.
They can occur due to fluctuating manufacturing lead times, supplier changes, or even a sudden spike in customer demand. You can, of course, try to plan to avoid these situations, but some moments are just simply out of your control.
That’s why it’s always important to have safety stock for your materials and finished products.
Safety stock is the quantity of a particular item that is always there in the background to avoid dreaded stockouts. It’s an emergency fund of inventory that guarantees your customers will always be able to get their products on time.
This is the basic stock replenishment formula you can apply to get your safety stock numbers:
