You’ve landed a feature in a reputable industry publication for one of your new products. It took you six months to get their attention, but you finally have! Once consumers read the feature, they arrive on your website in droves and want to buy your product. The only problem is, you’ve run out of stock for it.
By the time you get the inventory for the featured product back in stock, you might lose all the customers who were interested in it in the first place.
Demand planning helps you provide for your customers when they want to buy your products and helps you estimate how much inventory you need, when you need it.
Learn why demand planning is important and how you can build a demand planning strategy step by step.
What is demand planning?
Demand planning is the supply chain management process of predicting the future demand for a company’s products and using those predictions to organize its supply chain to meet that demand.
Why demand planning is important to ecommerce retailers
Demand planning isn’t necessary for new ecommerce brands that are just getting started, but it’s absolutely critical for fast-growing retailers that need to keep up with their customers. Here are some ways to ensure you’re accurately planning for demand.
Meet growing customer demands
If you’re a high-growth DTC or ecommerce brand, demand planning helps you meet demand as it grows.
At ShipBob, we’ve seen examples of retailers that grow at different speeds.
In one case, a ShipBob retailer grew from 2,000 orders per month to 20,000+ orders per month in a single year. Another ShipBob merchant grew more slowly, from 2,000 orders per month to 6,000 orders per month in just one year.
Both of these retailers use ShipBob’s inventory forecasting tools in their demand planning process to make sure they’re fulfilling demand as it comes to them.
Maintain healthy inventory levels
Demand planning helps you identify exactly how much inventory you should be holding to meet your business’s demand.
By combining your safety stock availability with your demand forecasting models, you’ll ensure that none of your in-demand products drop below their required inventory levels at the wrong time.
Boost customer satisfaction
When retailers use demand planning, they’re able to ensure higher order fulfillment which, in turn, boosts customer satisfaction.
If you don’t execute demand planning consistently, you run the risk of mismatching your inventory with your demand and disappointing your customers.
Keeping customers happy is a key aspect of returning business. 91% of customers won’t engage with an online store after they’ve had a bad customer experience.
By practicing demand planning, you’re making an investment in your customer retention strategy too.
Step by step guide to demand planning strategy
Now that you know what demand planning is and why it’s important, here’s how you can implement demand planning for your business:
Step 1: Implement inventory technology
Demand planning starts with tracking your inventory’s performance. Inventory management software helps you track your inventory levels, orders sales, and shipments.
If you don’t already have an inventory management system in place, here are a few options we recommend:
- Inventory Planner
All three of these options are web-based applications that either are mobile-friendly or have compatible mobile apps.
Step 2: Collect data
Once you’ve implemented your inventory management software, you’ll need to collect relevant internal data about your business’s order history and performance and external data about your business’s industry, market trends, and consumer behavior patterns.
For internal data, speak to your sales and marketing teams about successful promotions or moments when the business had a surge in demand. Map that qualitative information against the quantitative information around your business’s historical order data and inventory analytics.
For external data, gather industry briefings that document consumer behavior, news articles that share current market conditions, or celebrity social media mentions of your product. Are there any demand signals like market disruptions or natural disasters that might affect demand for your product lines? You’ll have to record them in this step of the process.
Step 3: Organize and analyze data
Now that you’ve collected your internal and external data, it’s time to organize and analyze it.
Some key metrics you should look out for in your data are sales numbers by channel, inventory turnover ratio, and backorder rate.
Is your business seasonal? If so, you should pay special attention to your inventory performance during peak and off-peak sales months.
Step 4: Select your demand forecasting method
Demand forecasting can be done through quantitative and qualitative methods. Here are a few different options to help you decide which method might work best for you:
- Exponential smoothing: This method leverages historical data to make its forecast, but accounts for seasonal variations as well. It’s useful for smaller companies because it can use smaller datasets to make its predictions.
- Regression analysis: This method examines the relationship between two or more specific variables to make its forecast.
- Econometric forecasting: This method is a more complex way of forecasting demand that combines internal and external data to arrive at a forecast.
- Delphi method: This method gathers the opinions and judgments of a small group of industry experts and advisors. These opinions and judgments are summarized by a third party before they’re shared with the business.
- Historical analysis: This method uses the sales history of a parallel product to evaluate future demand. For example, if you’re forecasting demand for a new body wash scent, you might look to past demand for existing body wash scents for your forecast.
- Panel consensus: This method brings internal stakeholders together to provide guidance on the demand forecast. For example, you can ask your customer service team which products are the highest rated by customers. You can also ask your sales team for insights on what customers are requesting from them.
Step 5: Forecast demand
With a mix of methods described above, you can now create your demand forecast.
Demand forecasts are prepared as spreadsheets and represented as trend charts.
Step 6: Make decisions & plans based on forecasted demand
Your demand forecast will help you plan your inventory, which is the last step in your demand planning strategy.
Inventory planning methods like the economic order quantity (EOQ) model use annual demand forecasts to arrive at an optimal inventory mix for your business.
Other factors that you should take into account include production lead times and supplier capacities since they will impact your ability to meet your forecasted demand.
Demand planning process best practices
Good demand planning requires the right software, data, models, and more. Here are a few best practices to ensure your demand planning process is on track:
Use the right software
Utilizing the right software will help you gather data when you need to plan your demand.
You can either choose an inventory management system that tracks your product performance, or you can go for an end-to-end fulfillment system like ShipBob, which tracks your orders from creation to delivery. ShipBob’s inventory management system even tracks returns when your customers need to send an order back to you.
Ensure you have accurate inventory data
Bad data leads to bad decisions in any organization, and the same is true of inventory data. Inaccurate inventory data is usually out-of-date, comes from unreliable sources within your operations, or is presented in confusing ways. It often has a negative impact on your forecast accuracy.
ShipBob’s inventory analytics give you a real-time view of your inventory, including metrics like:
- Fulfillment performance and SLAs
- Current inventory distribution vs ideal distribution
- Transit times, shipping methods, and destinations
- Historical stock levels
- Logistics costs associated with storage, fulfillment, and shipping
“Our favorite aspects of ShipBob’s fulfillment software are the algorithm and analytics. ShipBob’s analytics dashboard has a lot of valuable reports that show our top-selling states, order revenue and costs, units sold, sales by SKU, days of inventory, SKU velocity, sales vs. inventory distributions showing where our customers are and where we’re shipping from, and more.”

Prepare for holiday surges
Holiday season brings about a surge in demand, especially around Thanksgiving, Black Friday and Christmas. This year will be especially difficult for retailers with ongoing supply chain delays across the world.
What does this mean for you? Place your inventory orders in advance and have enough safety stock to account for last-minute orders placed during the holiday season.
Create data process models
Having a process model for your demand planning strategy helps you create an accurate plan.
Go through the steps in your demand planning process and identify which steps apply to your business and can be executed at the right time.
For example, you may want to consider organizing your internal data and conducting an initial forecast before you combine it with external data. Similarly, you may want to think about reconciling bottom-up and top-down forecasts together before arriving at a final forecast, depending on how much data your company has access to.
Set demand planning goals
Goals can help your demand planners organize and streamline your demand planning process.
Is your goal with planning demand to reduce your stockouts? Or is it to prevent overstocking? Are there past scenarios in your business you’re looking to avoid with your latest demand planning exercise?
Knowing this beforehand will help you design a plan that best suits your business objectives.
