Your online store is doing well, sales are growing… and suddenly, you run out of product.
The solution? **Having a proper safety stock**.
## **What is safety stock?**
Safety stock is an extra reserve of products kept to cover unforeseen events.
It’s not used daily, only when there are demand spikes or supplier delays.
It acts as a “logistics cushion” to prevent stockouts and missed orders.
## **Why is it so important?**
Running out of stock means:
- Lost sales
- Frustrated customers
- Damage to your brand reputation
An e-commerce without safety stock is always at risk.
## **When is it used?**
Safety stock is activated when:
- Demand rises unexpectedly
- Replenishment is delayed
- Forecasting or transport errors occur
- Market conditions change
## **How to calculate your safety stock**
There’s no single formula, but a simple approach is:
**Safety stock = Daily demand × Expected delay time**
Example: if you sell 20 units per day and your supplier may be delayed 3 days, you should have 60 extra units.
The key is to adjust this value based on your sales history and product type.
## **Tips for managing it well**
1. **Use a WMS with full visibility**
A good Warehouse Management System shows in real time how many units are available and how many belong to the safety stock.
2. **Check your order history**
Detect sales patterns and seasonality to adjust preventive stock before shortages occur.
3. **Integrate your inventory with your e-commerce**
Avoid selling out-of-stock products. At AMPHORA, we connect your store with our systems to keep stock synchronized.
4. **Don’t overstock**
Excess stock also generates costs. The key is balance: enough to respond quickly without overloading your warehouse.
Safety stock is more than a reserve: it’s peace of mind, control, and responsiveness.
At AMPHORA, we help your inventory flow smoothly, even when things get complicated.
