How it works: reorder point = sold per day × (lead time + buffer days). When your stock drops to that level or below, it's time to order.

Reorder point questions, answered

Simple answers for small shops and stalls.

What is a reorder point?

It's the stock level at which you should place a new order, so the new stock arrives before you run out. The formula is: sold per day × (lead time in days + buffer days). For example, 4 sold a day with a 1-day lead time and 1 buffer day gives a reorder point of 8.

How do I find how much I sell per day?

Add up the units you sold over the last 30 days and divide by the number of days you were open. A longer period gives a steadier number. If you track sales in Easy Ventory, your outgoing transactions give you this directly.

What is lead time?

The number of days between placing an order and having the stock ready to sell. If you buy from the market the same morning, that may be 0 or 1 day. For a supplier who delivers, it could be several days.

What are buffer days?

Extra days of stock kept as a cushion for busy days or late deliveries, often called safety stock. Use more buffer days for your best sellers or unreliable suppliers.

How is the suggested order quantity worked out?

It brings your stock up to enough for the lead time, the buffer, and the number of days you choose in "Order enough for", minus what you already have. Change that number to order more or less each time.

Does this update automatically?

No, it's a calculator based on the numbers you enter. Easy Ventory tracks your stock as it comes in and goes out, and flags low stock for you without an account or internet.
