SmartPrice — Degressive Pricing by Quantity

Automatic degressive pricing for Dolibarr

SmartPrice lets you define quantity-based price tiers on any product and applies them automatically when a line is added to a quote, order or invoice — no manual lookup needed.

Key features

• 3-level price resolution — customer-specific → customer category → product default
• Automatic trigger on quote, order and invoice line creation (LINEPROPAL_CREATE, LINEORDER_CREATE, LINEBILL_CREATE)
• Dedicated tab on Product, Third-party and Customer Category cards
• Unlimited tiers per product/customer/category combination
• VAT, local taxes and existing discount % are preserved on line update
• Translations: French · English · German

How it works

1. Open a product card → Degressive Pricing tab
2. Add tiers: from qty X → unit price Y — optionally restricted to a customer or customer tag
3. Done. When that product is added to a document for a matching customer and quantity, the correct price is applied instantly.

Price resolution logic (highest priority wins)

1. Customer-specific tier
2. Customer category (tag) tier
3. Product default tier (applies to all customers)

If no tier is defined for a product, the standard Dolibarr catalogue price is used unchanged.

Requirements

• Dolibarr 20.0 or later
• PHP 7.4 or later
