Customer-specific B2B pricing.
At scale. Without breaking your platform.

Quantaprice is a dedicated pricing engine that complements platforms like SAP Commerce Cloud and Adobe Commerce, enabling true customer-unique pricing with predictable performance, lower risk, and higher change velocity.

The real B2B pricing problem

Enterprise commerce platforms were built to manage catalogs, content, and checkout. In B2B, they are often forced to also solve a far harder problem: negotiated, customer-specific pricing across massive assortments.

The result is fragile pricing rules, shared catalog hacks, cache explosions, and performance that degrades as pricing complexity grows.

Embedded pricing vs decoupled pricing

Unlock the platform you already paid for

Quantaprice removes pricing pressure from your commerce platform, allowing it to do what it does best: deliver fast storefronts, stable carts, and reliable checkout flows.

Built for real B2B scenarios

• Negotiated contracts per customer
• Millions of SKUs with customer-unique prices
• Frequent price updates and imports
• Consistent pricing across webshop, punchout, EDI, and APIs

Who Quantaprice is for

Pricing is infrastructure. Treat it like one.

Quantaprice lets your commerce platform focus on selling products — while it focuses on pricing them correctly.

How it works in practice

The concepts above — inheritance, metadata, price rules — come together in a straightforward setup. Here's a complete walkthrough: a standard pricelist, one B2B customer with negotiated category discounts, and a single query that resolves the right price.

Organize your catalog with metadata

Articles in Quantaprice carry a free-form metadata object — key/value attributes you define to match your business. Instead of writing discount rules per SKU, you tag articles with categories, brands, and flags, and let rules target those tags.

PUT /api/v1/articles

[
  {
    "sku": "LBR-2X4-8FT",
    "name": "Lumber 2x4 8ft Spruce",
    "metadata": {
      "category": ["lumber"],
      "brand": ["northwood"],
      "unit": ["piece"],
      "no_discount": ["false"]
    }
  },
  {
    "sku": "ELC-CBL-25-3G",
    "name": "Electrical Cable 3G 2.5mm² 100m",
    "metadata": {
      "category": ["electrical"],
      "brand": ["voltline"],
      "unit": ["roll"],
      "no_discount": ["false"]
    }
  },
  {
    "sku": "TLS-DRL-18V",
    "name": "Cordless Drill 18V Kit",
    "metadata": {
      "category": ["tools"],
      "brand": ["kraftwerk"],
      "unit": ["kit"],
      "no_discount": ["false"]
    }
  },
  {
    "sku": "SAF-HLM-PRO",
    "name": "Safety Helmet Pro EN 397",
    "metadata": {
      "category": ["safety"],
      "brand": ["guardex"],
      "unit": ["piece"],
      "no_discount": ["true"]
    }
  }
]

category drives the discount rules we'll set up shortly. brand gives you another dimension for rules or reporting. no_discount is a custom flag — the safety helmet is marked true to exclude it from automatic discounting. Quantaprice doesn't prescribe any particular metadata keys; these are conventions you choose.

Metadata values are stored as lists, so even single values like "lumber" are wrapped in an array. This supports multi-value scenarios like "season": ["summer", "clearance"].

Create a standard pricelist

The standard pricelist is your baseline — the full price for every product. All customer pricelists will inherit from it.

PUT /api/v1/pricelists

{
  "code": "standard",
  "name": "Standard Pricelist",
  "currency_code": "SEK",
  "vat_mode": "NET",
  "description": "Base pricelist with full catalog pricing.",
  "metadata": {
    "type": ["base"]
  }
}

Then add fixed prices for every article:

PUT /api/v1/pricelists/standard/prices

[
  { "sku": "LBR-2X4-8FT",   "prices": [{ "quantity_break": 1, "fixed": 89.00 }] },
  { "sku": "LBR-PLY-12MM",  "prices": [{ "quantity_break": 1, "fixed": 345.00 }] },
  { "sku": "ELC-CBL-25-3G", "prices": [{ "quantity_break": 1, "fixed": 1250.00 }] },
  { "sku": "ELC-BRK-16A",   "prices": [{ "quantity_break": 1, "fixed": 189.00 }] },
  { "sku": "TLS-DRL-18V",   "prices": [{ "quantity_break": 1, "fixed": 2495.00 }] },
  { "sku": "TLS-SAW-CIRC",  "prices": [{ "quantity_break": 1, "fixed": 1890.00 }] },
  { "sku": "SAF-HLM-PRO",   "prices": [{ "quantity_break": 1, "fixed": 425.00 }] }
]

The NET VAT mode means prices are stored excluding VAT; tax is calculated during queries. The currency is SEK here, but Quantaprice supports 32+ currencies with automatic ECB exchange rate conversion.

Create a customer-specific pricelist

Instead of maintaining separate prices for every SKU for every customer, you create a customer pricelist that inherits from the standard list and applies discount rules on top.

PUT /api/v1/pricelists

{
  "code": "customer-12345",
  "name": "Customer Automotion Inc",
  "currency_code": "SEK",
  "vat_mode": "NET",
  "parent_code": "standard",
  "description": "Negotiated pricing for Automotion Inc.",
  "metadata": {
    "type": ["b2b"],
    "customerId": ["12345"]
  }
}

Define category discounts with price rules

Price rules are lightweight, deterministic modifiers attached to a pricelist. They run in the pricing pipeline after the base price is resolved from the inheritance chain, but before currency conversion, VAT, and rounding.

For Automotion Inc, the negotiated discounts are:

PUT /api/v1/pricelists/customer-12345

{
  "price_rules": [
    {
      "code": "lumber-discount",
      "expression": "article.metadata.category == 'lumber' && article.metadata.no_discount != 'true' ? price * 0.76 : price",
      "description": "24% discount on all lumber products"
    },
    {
      "code": "electrical-discount",
      "expression": "article.metadata.category == 'electrical' && article.metadata.no_discount != 'true' ? price * 0.83 : price",
      "description": "17% discount on all electrical products"
    },
    {
      "code": "tools-discount",
      "expression": "article.metadata.category == 'tools' && article.metadata.no_discount != 'true' ? price * 0.955 : price",
      "description": "4.5% discount on all tools"
    }
  ]
}

Each rule checks the article's metadata for the target category and respects the no_discount flag. The safety helmet, flagged as no_discount: true, is excluded from all three rules automatically.

Because rules target metadata rather than individual SKUs, they scale effortlessly. Add a thousand new lumber products to your catalog, and they get the 24% discount for Automotion Inc without any rule changes.

Query the right price

With everything configured, your e-commerce platform resolves the right price with a single API call. The pricelist_filter combines a named pricelist with metadata-based selection:

POST /api/v1/price/query

{
  "skus": [
    "LBR-2X4-8FT",
    "ELC-CBL-25-3G",
    "TLS-DRL-18V",
    "SAF-HLM-PRO"
  ],
  "pricelist_filter": {
    "pricelists": ["standard"],
    "metadata": {
      "type": ["b2b"],
      "customerId": ["12345"]
    }
  },
  "currency_code": "SEK",
  "tax_area": "SE"
}

pricelists: ["standard"] includes the named standard pricelist as a baseline. metadata matches any pricelist tagged with both type=b2b and customerId=12345 — which resolves to customer-12345. Quantaprice evaluates both and returns the best price for each SKU.

// Response
[
  {
    "sku": "LBR-2X4-8FT",
    "sales_price_ex_vat": 67.64,
    "sales_price_inc_vat": 84.55,
    "vat_rate": 0.25,
    "price": { "pricelist": "customer-12345", "currency_code": "SEK" }
  },
  {
    "sku": "ELC-CBL-25-3G",
    "sales_price_ex_vat": 1037.50,
    "sales_price_inc_vat": 1296.88,
    "vat_rate": 0.25,
    "price": { "pricelist": "customer-12345", "currency_code": "SEK" }
  },
  {
    "sku": "TLS-DRL-18V",
    "sales_price_ex_vat": 2382.73,
    "sales_price_inc_vat": 2978.41,
    "vat_rate": 0.25,
    "price": { "pricelist": "customer-12345", "currency_code": "SEK" }
  },
  {
    "sku": "SAF-HLM-PRO",
    "sales_price_ex_vat": 425.00,
    "sales_price_inc_vat": 531.25,
    "vat_rate": 0.25,
    "price": { "pricelist": "standard", "currency_code": "SEK" }
  }
]

The safety helmet wasn't discounted because the no_discount flag excluded it from all three rules. The response shows it resolved from standard rather than customer-12345.

Scaling to hundreds of customers

The pattern repeats for every customer:

Thousands of customer pricelists, each with their own rules, all inheriting from the same standard list. Add a new product and it's instantly available at the correct discount for every customer — no per-customer updates needed.

Need to change a customer's lumber discount from 24% to 26%? Update one price rule. Need a temporary campaign discount for Q4? Use scheduled updates to activate it at a specific date and have it automatically revert.
