Smart Options Pricing is a practical OpenCart module for live price recalculation when customers choose product options and change quantity. It updates the product price in real time, so shoppers instantly see what they will pay. This reduces confusion on product pages and helps customers make decisions faster.

The module works with regular price, special price, tax line, points, and reward values. It keeps the price block clean and consistent and can show smooth updates instead of abrupt changes. When a product has a special price, the regular price stays readable and the special price remains the main focus, just like buyers expect.

You can control how prices are displayed in two places. Product Price Mode defines whether the main price shows the final total or only the markup from selected options. Option Price Mode controls how each option value shows its price in the options list, either as a simple “+10” style markup or as the calculated full price. This makes the module useful for different store styles, from simple catalogs to stores with complex option pricing.

A separate Design & Styles section lets you adjust typography without breaking your theme. You can set font color, font weight, and individual font sizes for each price element, plus add your own custom CSS. This makes it easy to match the module output to any storefront design while keeping the original layout intact.
