Turn Excel Pricing Models Into APIs

Why Pricing Models Stay In Excel

Most pricing models start in Excel for a simple reason. Excel allows pricing teams to create, test and maintain reusable pricing logic without software projects. Over time these workbooks become the most valuable pricing asset inside the organization.

They contain years of accumulated business knowledge:

• customer agreements
• discount matrices
• quantity tiers
• margin calculations
• product group pricing
• regional pricing rules
• currency conversion
• special exceptions

The problem is rarely the pricing model itself.

The problem is making that pricing logic available across ERP systems, CPQ platforms, e-commerce applications, customer portals and custom software.

CLE turns Excel pricing models into reusable pricing APIs.
Business experts continue maintaining pricing models in Excel.
Applications consume pricing decisions through REST APIs.

Learn how CLE exposes business decisions through a Decision Engine API.

Real-World Pricing Models Are Full Of Lookup Tables

Most pricing models are not built from simple IF statements.

They contain pricing matrices, customer-specific agreements, product family adjustments and lookup tables that have evolved over many years.

A common example is a pricing factor matrix based on customer groups and product families.

The business user thinks in pricing matrices.
Applications simply provide customer groups and product families.
CLE executes the Excel model and returns the resulting pricing factor.

Pricing Should Be A Service

Pricing decisions are needed everywhere:

• ERP systems
• CPQ solutions
• E-commerce platforms
• Customer portals
• Procurement systems
• Product configurators
• Custom applications

Instead of rebuilding pricing logic in every application, organizations can expose a single pricing service.

One pricing model.
One source of truth.
Every application receives the same pricing decision.

The Problem With Pricing Logic In Application Code

Most organizations eventually outgrow manual spreadsheet workflows.

As pricing logic spreads across ERP systems, CPQ platforms, webshop integrations and custom applications, every change becomes a software project.

• The same discount matrix is implemented multiple times.
• The same pricing rule is maintained in multiple systems.
• The same business logic produces different results.

Pricing becomes harder to maintain, harder to explain and slower to change.
CLE centralizes pricing decisions in a single executable pricing model.

Pricing API Example

The following request uses the pricing matrix shown above. For a Retail customer purchasing Spare Parts, the Excel pricing model returns a pricing factor of 1.80. The resulting pricing factor is then used to calculate the final customer price.

Request

POST /api/decision
Content-Type: application/json

[{
  "customerGroup": "Retail",
  "productFamily": "Spare Parts",
  "quantity": 250,
  "purchasePrice": 85.50,
  "currency": "EUR"
}]

Response

HTTP 200 OK

[{
  "customerGroup": "Retail",
  "productFamily": "Spare Parts",
  "quantity": 250,
  "purchasePrice": 85.50,
  "currency": "EUR",
  "pricingFactor": 1.80,
  "retailPrice": 153.90,
  "tierLevel": 3
}]

Applications send business data.
CLE returns pricing decisions.

Real-Time Pricing From Existing Models

Modern applications cannot depend on manual spreadsheet execution.

Customers expect immediate responses.

Sales teams require instant quotations.

Commerce platforms need pricing decisions in real time.

CLE executes existing Excel pricing models through REST APIs.

No exports.
No imports.
No manual calculations.
No duplicated pricing logic.

Keep Existing Excel Pricing Models

Most pricing models already contain years of business knowledge.

Typical models include:

• IF formulas
• XLOOKUP
• VLOOKUP
• INDEX/MATCH
• SUMIFS
• customer-specific pricing
• quantity discounts
• pricing matrices
• regional pricing tables

CLE allows organizations to keep these Excel pricing models.

One Pricing Model. Every Application.

A single pricing model can power:

• ERP
• CRM
• CPQ
• E-Commerce
• Procurement
• Customer Portals
• Internal Applications

Every system receives pricing decisions from the same model.

No duplicated calculations.
No inconsistent pricing.
No synchronization projects.

Explain Every Price

Pricing decisions should never be black boxes.

Every calculated result can be traced back to:

• input values
• customer groups
• quantity tiers
• discount matrices
• margin factors
• lookup tables
• exchange rates
• intermediate calculations

Business users, developers and auditors can understand exactly how a customer price was generated.
