Development of a 1C-Bitrix pricing rules module

Developing a Pricing Rules Module for 1C-Bitrix

Prices in an online store aren't static. Discounts for bulk orders, seasonal markups, B2B partner rates, clearance prices — all need different rules. Standard Bitrix pricing doesn't handle complex rules. Pricing rules module allows flexible price management via rules.

Price Rule Types

• Bulk discount — quantity ≥ 10 → 5% discount
• User group discount — VIP customers → 10%
• Category markup — Electronics → +15%
• Time-based — Black Friday → -30%
• Regional pricing — Moscow → 1500₽, SPB → 1600₽
• Cart sum threshold — order > 5000₽ → free shipping

Rule Engine

Rule evaluation order-sensitive:

class PricingEngine
{
    public function calculate(Product $product, User $user, Order $cart): float
    {
        $basePrice = $product->getPrice();
        $rules = RuleTable::getActive();
        $discount = 0;

        foreach ($rules as $rule) {
            if ($rule->matches($product, $user, $cart)) {
                $discount = max($discount, $rule->getDiscount());
            }
        }

        return max(0, $basePrice * (1 - $discount));
    }
}

Configuration

Admin interface for creating rules:

• Condition builder (product, user group, cart sum, date)
• Action (fixed discount, percentage, fixed price)
• Priority (rule execution order)
• Date range (when active)

Frontend Integration

On product page and in cart, display:

• Base price
• Applied discounts
• Final price
• Reason ("Bulk discount for 10+ items")
