Once you configure inventory tracked products within Mews POS, you can create sellable products that automatically deduct inventory from these tracked products.

To do that, you must first configure automatic unit conversion within your inventory tracked product. Using automatic unit conversion, you instruct Mews POS on the quantity of sellable product within each unit of the inventory tracked product. This enables Mews POS to deduct the correct amounts from inventory when the corresponding sellable product is sold.

The unit conversion section is an essential part of inventory management. Incorrect configurations can lead to stock discrepancies or unfavorable inventory use.

 

In this article you can learn about:

Unit conversion example

Example 1: Conversion from bottle to liter

You buy one box containing 24 bottles, each bottle has a volume of  0.75 liters. Your provider invoices per box and you sell the item by bottle and by glass. The system tracks the product inventory by bottle. There are several configurations possible. 

Configuration: If you purchase by box and sell by bottle and glass,

Purchase unit: Bottle 

• Number of items: 24, this is the number of purchased units.  
• Single item unit: 1, this represents 1 bottle.   
• Package price: Price for 24 bottles. This is the price you pay for the purchase quantity.  
• Inventory unit: Bottle.   
• Inventory quantity: 1, counting 1 bottle as 1 unit.   

 

 Conversion: You need to enter 1 conversion.  

• The liters in a bottle.  

 

This information is necessary to create the composite product and to remove it from the inventory after a sale by glass.   

• Purchased Quantity: 1
• Source Unit: Bottle  
• Sellable quantity: 0.75
• Target Unit: liter 

Example 2: Conversion from box to tea bag 

You buy a box of 5 boxes of tea, each containing 50 tea bags. Your provider invoices you by the box and you sell the product by the tea bag. The system tracks the product inventory by the tea bag. There are several configurations possible. 

Configuration: If you purchase by the box and sell by one tea bag,

Purchase unit: Box, represents the box containing 5 tea boxes  

• Number of items: 5, the number of units of the package.  
• Single item unit: 1, this represents a tea box in the package.  
• Package price: Price for 5 tea boxes. This is the price you pay for the purchase quantity.   
• Inventory unit: Piece, this represents the tea bag.   
• Inventory quantity: 1, counting 1 unit of 1 tea bag.

 

Conversion: A conversion is necessary for the number of tea bags per box.  

• Purchased Quantity: 1
• Source Unit: Box  
• Sellable quantity: 50
• Target Unit: Pieces 

Example 3: Conversion from box to piece 

You buy 20 gram crepes in a box of 15 bags, each bag containing 12 crepes. Your provider invoices you by the box and you sell the product by the crepe. The system tracks the product inventory by individual crepe. There are several configurations possible. 

Configuration: If you purchase by the box and sell by individual crepe, 

Purchase unit: Box, represents a box of 15 bags. 

• Number of items: 1 box, the number of units of the package.   
• Single item unit: 1, this represents 1 crepe in a box of 15 bags.  
• Unit price: Price for 1 box of 15 bags. This is the price you pay for the purchase quantity.   
• Inventory unit: Piece, that represents the crepe. 
• Inventory quantity: 1, counting 1 unit for 1 crepe.  

 

Conversion:  

• Purchased Quantity: 1
• Source Unit: Box  
• Sellable quantity: 180, the sum of 1 box x 15 bags x 12 crepes.
• Target Unit: Pieces 

Example 4: Conversion consideration for kilogram product 

You buy 1 box containing 20 duck breast pieces. Your provider invoices you by the kilogram and you sell by the piece. The system tracks the product inventory by kilogram, not by piece or by box.  

 

This variation occurs because the weight of a duck breast can differ per piece, making it difficult to convert pieces to kilograms unless the provider ensures each duck breast weighs the same. In this case, it is not possible to apply automatic unit conversion.

 

Purchase unit: Kilogram, as the provider invoices by kilogram.  

• Number of items: 1, represents the number of units of the package.    
• Single item unit: 1, per kilogram.  
• Unit price: Price per kilogram. This is the price you pay for the purchase quantity.  
• Inventory unit: Kilogram  
• Inventory quantity: 1, counting 1 unit in kilograms.  

 

Conversion:  No conversion

 

After you configure automatic unit conversion for your inventory tracked products, you can now create and link sellable products to these inventory products to track stock changes automatically.
