If you've spent any time in the automotive aftermarket industry, you've likely encountered the acronyms ACES and PIES. These data standards are the backbone of efficient parts catalogs and inventory management systems that power successful eCommerce operations in the automotive sector.
ACES (Aftermarket Catalog Enhanced Standard) is the industry standard for managing and exchanging vehicle fitment data. It defines which parts fit which vehicles using standardized vehicle attributes. PIES (Product Information Exchange Standard), on the other hand, contains the product data itself—prices, weights, dimensions, descriptions, and digital assets. Together, they create a comprehensive product information ecosystem that enables accurate parts listings across the aftermarket industry.
For eCommerce businesses in the automotive parts sector, these standards aren't just technical requirements—they're essential competitive tools. When implemented correctly, they enable precise fitment information that connects customers with exactly the right parts for their vehicles, reducing returns and improving customer satisfaction.
As a marketing professional working with numerous automotive aftermarket clients, I've seen firsthand how proper ACES and PIES implementation can transform a struggling parts business into a well-oiled eCommerce machine. The difference between success and failure often comes down to how well these data standards are managed.
Managing ACES and PIES data isn't without significant hurdles. Let's examine the most common challenges that aftermarket businesses face when handling these complex data standards.

The complexity is staggering—a single part may fit hundreds of vehicle configurations, while a single vehicle might be compatible with thousands of different parts. Each connection point represents a potential error that could lead to a customer purchasing an incompatible part.
The most common accuracy issues include:
The aftermarket industry doesn't stand still, and neither do its data standards. PIES 7.2, released in March 2024, introduced JSON file support, requiring teams to adapt their data management approaches to accommodate these new formats. (Source: Automotive Aftermarket)
These constantly evolving standards present challenges for automotive parts retailers who must:
Siloed systems create another major headache. When your ERP, PIM, and eCommerce platforms don't communicate effectively, data synchronization becomes complicated and prone to inconsistencies. (Source: Sitation)
These integration challenges often manifest as:
After working with numerous eCommerce businesses in the automotive aftermarket space, I've identified six key strategies that consistently deliver results when managing ACES and PIES data. These best practices can help transform what's often seen as a technical burden into a competitive advantage.
Implementing a robust Product Information Management (PIM) system creates a single source of truth for all your automotive parts data. PDM Automotive's PIM solution has been shown to reduce fitment errors by 60% through automated audits and centralized management. (Source: PDM Automotive)
A dedicated PIM system offers several advantages:
When selecting a PIM solution for optimizing your product data for better conversion rates, look for one with specific ACES and PIES validation capabilities built in. This ensures your data remains compliant with industry standards while streamlining your overall product management workflow.
Monthly audits and validation using specialized tools like AutoCare's VCdb (Vehicle Configuration database) and PCdb (Product Classification database) checks can proactively identify and prevent errors before they impact your business. (Source: PDM Automotive)
An effective audit schedule might include:
Audit Checklist
Create a standardized audit process that examines:
Technical knowledge gaps often create barriers to effective ACES and PIES implementation. Workshops focused on interpreting complex VCdb codes (for example, understanding the difference between "Engine CC" and "Engine Cubic Centimeters") significantly improve team alignment and data accuracy.

Training shouldn't be limited to just your technical team. Cross-functional education helps ensure everyone understands how these standards impact their area of the business:
Effective data management requires smooth collaboration across departments. Companies implementing shared data dashboards for cross-team visibility have observed a 30% reduction in product returns and customer complaints related to incorrect fitment information. (Source: APA Engineering)
To enhance collaboration around ACES and PIES data, consider:
How can data-driven management strategies improve performance when promoting auto parts? The quality of your product data directly impacts your PPC campaign performance, particularly for Google Shopping, where high-quality product feeds can dramatically improve click-through and conversion rates.
Manual data management is inefficient and error-prone. Modern APIs can sync PIM systems with eCommerce platforms, enabling real-time updates and reducing the risk of outdated or incorrect information reaching customers. (Source: Spark Shipping)
Effective automation tools for ACES and PIES data management include:
When evaluating automation solutions, prioritize those with specific automotive aftermarket capabilities and proven integration with the reporting tools for eCommerce performance measurement that you're already using.
The Auto Care Association requires subscriptions to essential databases like VCdb (Vehicle Configuration Database) and PAdb (Product Attribute Database) to maintain compliance with current standards. (Source: Auto Care Association)
Staying current with evolving standards involves:
How do you know if your ACES and PIES management strategy is working? Implementing key performance indicators (KPIs) helps track progress and justify the investment in these data standards.

Key metrics to monitor include:
For eCommerce businesses, these standards directly impact the bottom line through an effective Google Shopping strategy. Well-structured product data improves visibility, increases click-through rates, and enhances conversion rates for auto parts retailers.
Several specialized tools can help streamline ACES and PIES data management. Here are some worth investigating:
Industry associations also provide valuable resources:
Resource Recommendation
The Auto Care Association's Technology Standards Committee produces regular updates and best practices documents that are invaluable for staying current with ACES and PIES requirements.
As automotive technology evolves, so too do the data standards that support the industry. Several emerging trends will impact ACES and PIES management in the coming years:
Preparing for these trends requires developing a flexible data architecture that can adapt to new requirements without requiring complete system overhauls.
Effective ACES and PIES data management isn't just a technical requirement—it's a business advantage that directly impacts your bottom line through improved customer experience, reduced returns, and more efficient operations.
By centralizing your data management, implementing regular audits, training cross-functional teams, streamlining collaboration, leveraging automation, and staying current with industry standards, you'll position your automotive parts business for success in an increasingly competitive marketplace.
The companies that excel at managing these complex data standards will be the ones that win in the automotive aftermarket eCommerce space. Rather than viewing ACES and PIES as technical hurdles, see them as opportunities to differentiate your business through superior product information that helps customers find exactly the parts they need.
