Did you know there’s a metric that could revolutionise your order fulfilment process and boost customer satisfaction? It’s called the fill rate, and it’s an important tool for successful eCommerce fulfilment.
If you run an eCommerce business, you’ve probably experienced the frustration of not having enough stock to meet customer demand. This common problem can lead to unhappy customers, lost sales, and a damaged reputation. But what if there was a way to avoid these issues and keep your business running smoothly?
That’s where the fill rate comes in. By mastering this benchmark, you can get on top of your inventory, streamline your operations, and keep your customers coming back for more. In this guide, we’ll walk you through everything you need to know about how to calculate fill rates and how to use this information to supercharge your eCommerce success.
What is Fill Rate?
Fill rate measures how well you’re meeting customer demand with your available inventory. In simple terms, the fill rate is the percentage of orders you can fulfil completely from stock on hand.
Why is this so important? Well, imagine you’re a customer ordering a new outfit for a special occasion. You’d be pretty disappointed if only part of your outfit arrived, say your suit trousers but no shirt or jacket. That’s the kind of situation a good fill rate helps you avoid.
A high fill rate means you consistently meet customer expectations, which is important for building trust and loyalty. Whereas, a low fill rate can lead to frustrated customers, cancelled orders, and missed opportunities for growth.
Different Types of Fill Rates
Let’s talk about fill rates. There’s not just one type, but a few different options to measure how well you’re meeting customer orders. Don’t worry – they’re not as complicated as they sound, and each will tell you something useful about your business.
The Basic Fill Rate Formula
For example, if a customer orders 10 items and you can ship 9 of them, your fill rate for that order would be (9/10) x 100 = 90%.
While this basic formula is a good starting point, there are variations you might want to consider depending on your business needs:
Line Fill Rate
The line fill rate measures the percentage of order lines completely filled. Order fill lines refer to each individual type of product or item listed in an order. Instead of looking at individual items, it focuses on whether each line in an order (which could contain multiple items) was fully met.
For example, if an order has three lines:
- 10 red t-shirts
- 5 blue jeans
- 8 hats
If you successfully deliver all 10 red t-shirts and all 8 hats, but only 3 out of 5 the jeans, then the line fill rate would consider only lines 1 and 3 as complete. Line 2 would not be counted as fully filled.
In this case, 2 completely filled lines / 3 total lines = 66.7% line item fill rate.
This metric helps you to understand how well you are meeting the demand for entire lines of orders, which can be important for customer satisfaction and inventory management.
Order Fill Rate
The Order Fill Rate is a way to check how well you fulfil customer orders. It shows the percentage of orders that are shipped in full and on time.
Complete orders mean that all items in the order are delivered. If an order includes multiple items, every single one must be included in the shipment for the order to be considered complete. The order must also be delivered by the promised delivery date.
For example, if you receive 100 orders in a month and you ship 90 of them completely and on time, your Order Fill Rate would be:
(90 / 100) × 100 = 90%
A high order fill rate shows that a company is reliably meeting customer expectations for both completeness and delivery times, which is important for keeping your customers happy and building brand loyalty.
Case Fill Rate
The case fill rate is a useful measure for businesses that ship products in bulk, like cases or pallets, instead of individual items. It shows the percentage of cases or pallets that you ship completely filled and as requested.
For example, if you need to ship 100 cases and you ship 95 of them with the correct number of items, your Case Fill Rate would be:
(95 / 100) × 100 = 95%
This metric is especially helpful when stock is ordered in bulk, as a high case fill rate means your inventory management and fulfilment processes are efficient and reliable.
Steps to Calculate Fill Rate
Calculating your business’s fill rate regularly is important because it helps you work out what is or isn’t working. You might have a temporary glitch in your systems or supply chain, but without the data and context, bigger problems might go unnoticed. Your analysis will only be as good as the data you use, so it’s important to have a clear process for calculating the fill rate.
1. Gather Your Inventory and Fulfilment Data
You’ll need information on total orders, items ordered, and items shipped. This might come from your order management system or inventory software.
To get reliable data, consider how you handle partial shipments. Some businesses only count an order as filled if it’s completely shipped, but this can mess up your results. Be clear about how you count these partial shipments to maintain consistency.
Don’t forget about delivery timing. Even if an order is complete, a late shipment can still upset a customer. Including on-time delivery in your calculations will give you a more complete picture of your order fulfilment performance.
2. Choose Your Timeframe
Decide whether you want to calculate daily, weekly, or monthly fill rates. Consistency is king here. To keep everything accurate and reliable, use the same timeframe and data sources for all your calculations.
3. Apply the Fill Rate Metrics
Use the basic fill rate formula or one of the variations we mentioned earlier. While the basic formula is a good starting point, it’s helpful to explore the other metrics too, as they can provide a clearer understanding of your operations.
4. Analyse the Results
A fill rate of 100% is perfect, but anything above 95% is generally considered good.
5. Improve Your Order Fill Rate
Knowledge is power. If you’re falling short of a good fill rate percentage, don’t panic – we’ll cover improvement strategies later.
What is a good fill rate?
While a 100% fill rate might sound ideal, it’s not always practical or cost-effective.
When you’re figuring out what’s a good fill rate for your business, there are a few things to keep in mind. First off, try to find out what is normal in your industry. You might find that what’s considered great in your sector is different from others.
Then, think about your business model and your customers’ expectations. If you’re making things to order, your fill rate expectations will differ from those of a shop that sells ready-made products. If you’re selling luxury goods, your customers might be less forgiving about out-of-stock items compared to those shopping for everyday items.
Just to play devil’s advocate, while achieving a near-perfect order fill rate is excellent for the customer, it might not be the right move for your business. In many circumstances, it’s not realistic to overstock just to have it sit around, costing money. You have to find the balance between maintaining a good fill rate and managing your inventory efficiently.
Try to aim for steady improvement rather than perfection. Even small boosts in your fill rate can make a big difference. Your customers will be happier, and you’ll likely see it reflected in your bottom line too.
How To Improve Fill Rate
Getting good-quality data and accurate fill rates is just the first step. What you do with that information really counts in giving your company a boost.
Forecasting Demand
By looking at your historical data and keeping an eye on market trends, you can get a pretty good idea of what’s likely to fly off the shelves in the coming months. This foresight can help you stock up on the right items at the right time, keeping your fill rate healthy.
Build a Safety Net
Next, consider the idea of safety stock. Think of it as a rainy day fund but for your inventory. Keeping a little extra of your most popular items can be a lifesaver when demand unexpectedly spikes. It’s all about finding that sweet spot between being prepared and not tying up too much cash in excess stock.
Nurture Your Supply Chain
Your suppliers are your partners in this game, so nurturing those relationships is important. Regular communication can help ensure your orders are delivered on time and in full. Don’t be shy about discussing your needs and expectations – a good supplier will be keen to help you succeed.
Pay Attention to Inventory Management
Inventory management is an ongoing task, not a one-time thing. Make it a habit to review your stock levels and reorder points regularly. It’s like giving your inventory a health check-up. This way, you can spot potential issues before they become real problems and keep your stock at that optimal level. Check out our Inventory Costs guide for tips on how to calculate inventory costs and how to reduce fulfilment costs.
Audit Your Fulfilment Process
Take a good look at your picking, packing, and shipping processes. Are there any bottlenecks? Any areas where errors tend to creep in? Streamlining these processes can help reduce mistakes and speed up deliveries, both of which contribute to a better fill rate.
Use Tech To Calculate Your Fill Rate
If you think calculating fill rates will involve late nights with a calculator and a spreadsheet, think again.
Smart inventory management systems can give you real-time insights into your performance and spot trends in your data that you might miss. They’re like having a super-smart assistant who never sleeps, always keeping an eye on your stock levels and customer demand. Some can even predict when you’re likely to run low on items and automatically reorder for you.
