Running out of stock is one of the most common challenges Amazon sellers face. While keeping inventory levels low may reduce storage costs, waiting too long to reorder can result in lost sales and disruptions to your business.
Knowing when to reorder inventory is an important part of maintaining healthy stock levels and ensuring your products remain available to customers on Amazon Australia.
Why Timing Matters
Inventory does not arrive instantly. Between placing a purchase order, manufacturing, shipping, receiving, and Amazon check-in times, several weeks may pass before stock becomes available for sale.
If you wait until inventory is nearly depleted, there may not be enough time for replacement stock to arrive before you run out.
Understand Your Lead Times
Lead time refers to the total time it takes for new inventory to become available for sale.
This may include:
- Supplier production time
- Freight transit time
- Customs clearance (if applicable)
- Warehouse receiving
- Amazon FBA preparation
- Amazon fulfilment centre check-in
Understanding your average lead time is one of the most important factors when planning reorders.
Monitor Sales Velocity
Sales velocity refers to how quickly your products sell.
For example, if a product sells 10 units per day and you have 300 units remaining, you may have approximately 30 days of stock available.
Tracking sales trends helps you estimate when inventory will be depleted and when a reorder should be placed.
Consider Seasonal Demand
Sales patterns often change throughout the year.
Promotions, holidays, and seasonal buying trends can increase demand significantly. Sellers who only look at current sales levels may underestimate future inventory requirements.
Planning ahead helps reduce the risk of stock shortages during busy periods.
Build in a Safety Buffer
Unexpected delays can occur at any stage of the supply chain.
Freight delays, supplier issues, or receiving backlogs can affect inventory availability. Maintaining a safety stock buffer can help protect against these disruptions and reduce the likelihood of stockouts.
Avoid Waiting Until Stock Is Low
A common mistake is waiting until inventory reaches critically low levels before reordering.
By that point, there may not be enough time to replenish stock before inventory runs out. Proactive inventory planning helps maintain sales momentum and avoids unnecessary disruptions.
