A purchase run is used to determine what products need to be ordered, and in what quantities. Readysell provides two basic ways to calculate this: by defining minimum and maximum stock levels for a product (Min Max), or by considering average weekly sales.

Product fields

Each product has a number of fields that govern how it behaves in a purchase run. These fields are set on the Products screen. The table below shows how each field is used in a purchase run, and the tab within the Products screen where each one is located.

FieldWhat it doesUsed inTab
Min Reorder Quantity

When the quantity on hand for any product reaches or falls below the value set in the field of 'Min Reorder Quantity', the system will automatically re-order the product in the next appropriate purchase run. 

Once the Minimum reorder quantity is reached = Maximum Reorder Qty -  Nett Quantity on hand .

Min MaxGeneral tab
Max Reorder QuantityWhen reordering this product, order enough stock until the Value in the Maximum Reorder. Maximum Reorder quantity - nett quantity on hand.Min MaxGeneral tab
Min Order Quantity

It is the minimum quantity which the supplier requires you to order in. EG min qty = 2 means if the product is purchased by each, you must buy at least 2. If the product is purchased by box or pack you must buy at least or 2 or by multiples of 2 from the.supplier. The system will always round up.

Formula = max reorder qty - net qty on hand / min order qty if the pack break is not in eaches eg max reorder = 100 net qty on hand = 10 min reorder qty = 20. purchase order run will order 100 - 10 = 90. Then the system will divide the 90 by the min order qty of 2 = 45 only if the buy unit is not in eaches or box of 1 etc .

Purchase Run Set fields

Each purchase run set has a number of fields that govern how products are selected to order. The table below gives a brief description of each field.

...

Count of Weekly Sales = the average number of sales per week over the date range that contained at least one line with the product in it

...

Quantity of Weekly Shipments = the average weekly each quantity of products shipped over the date range

...

The amount of stock that will be reordered is equal to weeks of floor stock x the quantity of weekly shipments

...

Readysell multiplies the average quantity sold per week by this number to get the acceptable sales variance. If a week's total sales differ from the average by more than this amount, that week's sales are excluded from the calculation.

This is particularly relevant for products where the quantity sold varies significantly in some weeks (such as seasonal stock).

...

If you want to ignore a particular field, you must set it to 0.The topics in this section provide you with information about how to use the Purchase runs functionality within Readysell.
