How does competitive price monitoring work?

The engine scrapes or polls competitor pricing data on a schedule. When a competitor price is detected below your threshold, the auto-adjust rule reduces your price to the configured differential, respecting your margin floor.

What is a margin floor?

A margin floor is the minimum gross margin percentage you'll accept. The engine prevents any pricing rule from setting a price that would result in a margin below the floor, protecting you from accidental loss-leader pricing.

How does A/B price testing work?

You define two price points for a product and split your audience (by percentage, geography, or session). The engine serves each group their price and tracks conversion rates and revenue per visitor to determine the winner.

The Challenge

Why building a Pricing Engine from scratch is hard

Building a Dynamic Pricing Engine from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing pricing engine-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Pricing Engine needs

ProjectCode generates a production-ready Pricing Engine with all the modules your team needs from day one.

Rule-based pricing with segmentation and conditions

Competitive price monitoring and auto-adjust rules

Time-based promotions and flash sale scheduling

Bundle pricing and kit configuration

Customer-specific pricing by account or tier

Margin floor protection to prevent negative margin pricing

Price change audit log with rollback capability

A/B price testing framework

Architecture

How it's built

The generated Pricing Engine follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for pricing engine workflows

NestJS REST API with dedicated pricing engine modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all pricing engine entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live pricing engine status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Pricing Engine

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

price_rules (id, name, type, conditions jsonb, adjustment, priority, starts_at, ends_at, is_active, workspace_id)
price_lists (id, name, currency, customer_group_id, base_adjustment, product_overrides jsonb, workspace_id)
competitor_prices (id, product_id, competitor_name, price, url, scraped_at)
price_history (id, product_id, price_list_id, old_price, new_price, changed_by, changed_at, rule_id)

FAQ

Common questions about building a Pricing Engine

Rules are evaluated in priority order from highest to lowest. The first matching rule applies its adjustment. If no rule matches, the base price list price is used. You can configure fallback behavior per product category.
