Understanding ACES/PIES Standards in Automotive Data Exchange

The automotive aftermarket industry processes billions of parts transactions annually, each requiring accurate vehicle fitment and product information. ACES (Aftermarket Catalog Exchange Standard) and PIES (Product Information Exchange Standard) have emerged as the definitive standards for organizing and exchanging this critical data. Understanding these standards is essential for anyone involved in automotive parts distribution.

What Are ACES and PIES?

ACES: Aftermarket Catalog Exchange Standard

ACES standardizes how vehicle application data is formatted and exchanged. It answers the fundamental question: "What vehicles does this part fit?"

Key Components:

• Vehicle Identification: Year, make, model, and submodel
• Engine Configuration: Displacement, fuel type, aspiration
• Part Applications: Which parts fit which vehicles
• Installation Notes: Position, quantity, and special requirements

PIES: Product Information Exchange Standard

PIES complements ACES by standardizing product information. It answers: "What is this part and what are its characteristics?"

Key Components:

• Product Details: Part numbers, descriptions, specifications
• Pricing Information: List prices, core charges, MAP pricing
• Digital Assets: Images, PDFs, installation videos
• Product Attributes: Dimensions, weight, materials, features
• Packaging Data: Unit of measure, package quantities

Why ACES/PIES Standards Matter

1. Industry Efficiency

Before standardization, each company used proprietary formats:

• Then: 100 suppliers × 50 distributors = 5,000 custom integrations
• Now: 1 standard format = seamless data exchange

2. Reduced Errors

Standardized data significantly reduces:

• Incorrect fitment claims
• Part number confusion
• Pricing discrepancies
• Missing product information

3. Faster Time to Market

With ACES/PIES:

• New products launch faster
• Updates propagate instantly
• Seasonal catalogs deploy efficiently
• Market coverage expands rapidly

4. Enhanced Customer Experience

End customers benefit from:

• Accurate fitment information
• Complete product details
• Consistent data across platforms
• Reduced returns and exchanges
