This article explores the fundamentals of lead times, how to use them in our app, and their broader impact on the global supply chain.
Most importantly, we will try and provide you with actionable strategies to avoid stockouts and optimize inventory, ensuring they stay competitive and profitable.
Understanding Lead Times in Retail
What is Lead Time?
Lead time is defined as the total time from the placement of a purchase order for replenishing products to the reception of the order in the warehouse. In retail, this typically includes the procurement time for finished products plus the shipping time to the store or warehouse.
Lead time is a multifaceted concept that involves coordination across suppliers, manufacturers, logistics providers, and retailers. It is a critical metric because it directly impacts inventory levels, customer satisfaction, and operational efficiency.
Types of Lead Times
Lead times can be broken down into three main components:
Lead Time Type
Definition
Key Influencing Factors
Typical Duration
Supplier Lead Time
Time for suppliers to process and ship your order
Supplier reliability, order volume, production capacity
1-12 Weeks
Production Lead Time
Time to manufacture the product (if applicable)
Factory efficiency, labour, raw material availability
1-8 Weeks
Shipping Lead Time
Time for transportation to your location
Shipping method, distance, customs, weather
1-4 Weeks
These components add up to your total lead time, which dictates how far in advance you need to place orders.
Why Lead Times Matter for your Business
Mismanaged lead times can lead to two major problems:
- Stockouts: Running out of products when customers want them, resulting in lost sales and damaged reputation.
- Overstocking: Holding too much inventory, which ties up cash and increases storage costs.
For example, if you underestimate a supplier’s lead time, you might place an order too late and miss out on sales during peak periods. On the other hand, overestimating lead times can leave you with excess stock that’s costly to store and risks becoming obsolete.
How Shelf Planner Helps You Master Lead Times
Shelf Planner is designed to take the guesswork out of lead time management.
Here’s how it works:
- Automated Reorder Points
Shelf Planner calculates the ideal time to reorder based on your lead times, sales velocity, and safety stock levels. No more manual calculations or last-minute panic orders.
- Dynamic Lead Time Tracking
Shelf Planner monitors supplier performance and adjusts reorder points automatically if lead times change, so you’re always prepared.
- Demand Forecasting
By analysing your sales history and seasonal trends, Shelf Planner predicts future demand, ensuring you order the right amount at the right time.
- Weeks of Stock (WoS) Parameters
This feature helps you determine how much stock to keep on hand based on your sales rate and lead time, so you’re never caught off guard.
External factors, like global supply chain disruptions, natural disasters, or geopolitical events, can also extend lead times unexpectedly.
The COVID-19 pandemic, for instance, caused widespread delays, with many retailers facing stockouts due to prolonged lead times.
Even seemingly minor events, like a ship stuck in a canal, can still affect your business negatively.
Practical Strategies to Avoid Stockouts
Managing lead times effectively is the key to keeping your shelves stocked and your customers satisfied.
Below are the five most impactful strategies to help you avoid stockouts, each designed to optimise your inventory and protect your bottom line.

1. Improve Demand Forecasting
Accurate demand forecasting ensures you order the right amount of stock at the right time.

- Utilise to automate predictions and adjust for variability.
the results
By improving your demand forecasting, you’ll minimise guesswork, reduce overstocking, and ensure you have the right products available when customers want them—boosting sales and customer loyalty.
3. Calculate Reorder Points Accurately
Reorder points determine when to replenish stock, balancing the risk of stockouts against the cost of overstocking. Precise calculations ensure you reorder just in time to meet demand without holding unnecessary inventory.
How to do it
- Set your Weeks of Stock (WoS) to determine your needed stock based on future demand.
- Set your lead times, Minimum Order Quantities (MOQ’s) and Pack Sizes for all of your products
- Let Shelf Planner automate this process, so you never miss a deadline again.
the results
You’ll maintain optimal stock levels, reduce emergency orders, and free up cash flow by avoiding excess inventory.
3. Strengthen Supplier Relationships
Strong supplier relationships lead to more reliable lead times, better terms, and priority treatment during shortages. When suppliers understand your business needs, they’re more likely to accommodate rush orders or provide flexibility during disruptions.

Frequently asked questions
Add up the time for procurement, production (if applicable), and shipping. Ask your supplier for their estimated lead time and factor in any potential delays.
If you don’t know the specific lead time for a product, you can apply a default lead time for the supplier. With every order you place, we calculate the average lead time by product type and by supplier that we use in the reorder recommendations.
Lead times vary widely. Fast-moving products (e.g., groceries, fashion) typically have shorter lead times (1–4 weeks), while custom or imported goods may take 8–24 weeks.
