How to Adjust Quantity Based on the Price

SalesPlay Back Office

Example Scenario

  • Product: Cashew nuts
  • Unit Price: US$ 0.12 per gram
  • Customer's Requested Amount: US$ 10
  • Total Quantity = US$ 10 / US$ 0.12 ≈ 83.33 grams


The user inputs US$ 10

The system automatically calculates the quantity: 83.33 grams


Instead of specifying the quantity, the user inputs the total value the customer is willing to spend on a particular product. For example, a customer wants to buy Cashew nuts for US$ 10.


The system, equipped with the "Adjust Quantity Based on Price" feature, performs an automatic calculation based on the product's unit price. In our example, if Cashew nuts are priced at US$ 0.12 per gram, the system calculates that the customer should receive approximately 83.33 grams of Cashew nuts for the specified US$ 10.
