On a schematic way, the problem is: The products we will sale in our website are merchandising products which can be customized (for instance, pens on which a logo can be silkscreened) There are many ways to customize the product (for instance, with one or two colours). So far, no problem, because we are talking about "product combinations" and PrestaShop supports this functionality. The problem is that the impact on the price of each of the combinations is not fixed (not a fixed amount or a fixed percentage), but ranges depending on the amount of products. This "impact on the price depending on the type of combination and quantity of items to customize" is in addition to the "impact on the price depending on how many products 'base' (ie without personalization) and have already met with dithering of prices depending on the amount PrestaShop allows to define the 'base' product. At the end of this post there is a clarifying example. We need a budget to develop this functionality. If you know any existing module to solve this problem, your job will be to verify that the module will meet our needs without problems, install the module and test it. Example: ======== PRODUCT PRICE WITHOUT CUSTOMIZATION: Quantity of products 'Base' price ===================== ============ 0 - 500 5,00 €/unit 501 - 5000 4,00 €/unit > 5000 3,00 €/unit PRICE INCREASE DEPENDING ON CUSTOMIZATION'S TYPE (for instance, 1 color silkscreen or 2 colors silkscreen): Quantity of products 1 color silkscrenn 2 colors silkscreen ===================== ================== =================== 0 - 1000 +0,15€/unit +0,30€/unit 1001 - 2000 +0,10€/unit +0,20€/unit > 2000 +0,05€/unit +0,15€/unit For instace, if the user buys 1.000 pens with a 2 colors silkscreen, the total price will be: 'Base' product: 4,00*1000 = 4.000€ Customization: 0,30*1000 = 300€ ---------------- ------ TOTAL: 4.300€
