Discount management system

We need to improve the discount system

For example:

• 2 pieces of the same brand come with the third product as a free option and in that case, take the low unit price as a free

• You can also implement like first 2 pieces will have no discount and the third product with a 50% discount

Need the discount to be applied across all locations when I create it.

Add more promotional and discount features like

• Buy X Get Y Promotion

• Discount Promotion (flat/percentage)

• Promotion Date Range

• Promotion Status
