Rules Engine

Pricing Rules Engine for Ecommerce

Manual repricing is slow, inconsistent, and error-prone. Price Patrol's rules engine lets you define pricing logic once, then lets automation handle the execution — with built-in guardrails to protect your margins.

Knowing what competitors charge is only half the equation. The other half is deciding what to do about it and executing that decision consistently across your entire catalog. This is where most merchants struggle. You see a competitor drop their price and manually adjust yours. But by the time you update the spreadsheet, log into Shopify, and change the price, hours or days have passed. Then you forget to change it back when the competitor raises their price again. You end up with inconsistent pricing that neither maximizes revenue nor protects margins.

A pricing rules engine automates this entire decision-and-execution cycle. Instead of manually reacting to every competitor price change, you define rules that describe your pricing strategy: "Match the lowest competitor price but never go below $24.99." "Undercut the market leader by 3% but cap at 15% below MSRP." "If all competitors are above $50, set my price to $49.99." The engine evaluates these rules every time new competitor data arrives and adjusts your Shopify prices automatically.

Price Patrol's rules engine is built specifically for e-commerce pricing. Rules are defined per product or in bulk across categories. Every rule includes mandatory floor pricing to prevent the race-to-the-bottom trap. MAP compliance settings ensure you never price below manufacturer requirements. And because all changes are logged, you have a complete audit trail showing when prices changed, why they changed, and what rule triggered the adjustment. This is pricing on autopilot — but with guardrails.

Key Benefits

Rule Templates

Start with proven rule templates: match lowest, undercut by percentage, maintain position, or beat specific competitor. Customize from there.

Margin Guardrails

Every rule requires a floor price. The engine will never reprice below your minimum profitable price, no matter what competitors do.

MAP Compliance

Set Minimum Advertised Price limits per product. The rules engine ensures your automated pricing never violates manufacturer pricing agreements.

Batch Rules

Apply rules across entire product categories or your full catalog at once. No need to set up rules product by product for large inventories.

Change Audit Trail

Every automated price change is logged with the rule that triggered it, the competitor data that prompted it, and the before/after prices.

Instant Execution

When new competitor data triggers a rule, your Shopify price updates automatically. No manual intervention, no delays, no forgotten updates.

How It Works

Get started in minutes with a simple setup process.

1

Define Your Rules

Choose a strategy: match lowest competitor, undercut by a percentage, maintain a specific position, or create custom logic. Set floor prices for margin protection.

2

Apply to Products

Assign rules to individual products or apply them in bulk across categories. Each product can have its own rule or inherit a category-level rule.

3

Automation Takes Over

Every time competitor prices are checked, the rules engine evaluates your pricing and makes adjustments automatically. Review the audit log anytime.

Use Cases

High-SKU Retailers

Stores with hundreds or thousands of products cannot manually reprice. Batch rules let you set competitive pricing across the entire catalog effortlessly.

MAP-Bound Brands

Brands with Minimum Advertised Price agreements need pricing automation that respects MAP limits. Price Patrol's rules engine enforces MAP as a hard constraint.

Competitive Categories

In fast-moving categories like electronics or fashion, competitor prices change daily. Automated rules ensure you respond immediately instead of hours or days later.
