Automotive Aftermarket PIM Software Guide

PIM - Product Information Management Marketing

An aftermarket brake rotor can fit dozens of vehicles, replace three older part numbers, ship in two package sizes and need a California warning label. Multiply that by 20,000 SKUs, and the spreadsheet that used to run your catalog starts sending customers the wrong parts.

Automotive aftermarket PIM software keeps parts data, fitment, specifications and digital assets in one system and sends them to each sales channel and trading partner in the format that partner accepts. The sections below show why parts data breaks spreadsheets, what the ACES and PIES standards ask of suppliers, and which questions to put to a vendor before you choose a PIM for automotive parts.

What Is PIM for Automotive Parts?

A product information management (PIM) system for automotive parts holds everything a buyer needs to pick the right part: part numbers, specifications, vehicle applications, images, installation guides and compliance data. Sales, marketing and catalog teams edit the same record instead of copying data between the ERP, supplier files and storefronts.

The difference from a general product catalog is the link between parts and vehicles. A T-shirt has a size and a color. A water pump has a list of vehicles it fits, notes that narrow that list, older part numbers it supersedes and competitor numbers it replaces. A parts PIM has to store these links as records tied to standard vehicle IDs, so they can be checked and exported, which a spreadsheet does not do on its own.

A PIM does not replace your ERP or file storage. Each system has its own job:

If the PIM has built-in digital asset management, each file is attached to its SKU from day one and nobody has to match them later.

Why Aftermarket Parts Data Is Harder Than Typical E-commerce

Most product catalogs describe what an item is. An aftermarket catalog also has to describe where the item fits, what it replaces and how each trading partner wants to receive that information. Each of the three gets its own section below, followed by what mistakes in them cost.

Fitment: One Part, Hundreds of Vehicles

Fitment (also called application data) links a part to the vehicles it fits, usually by year, make, model and engine. In practice, four fields are rarely enough. A single application may depend on submodel, drive type, body style, brake system or a production change halfway through a model year. Qualifiers and exclusions like these stop a customer from ordering front pads for a car with a different caliper.

OE Numbers, Interchanges and Supersessions

Buyers search by the number they already have. That might be the original equipment (OE) number, a competitor's part number or an older number from your own catalog. Interchange data maps those numbers to your part, and supersession data records which part replaces a discontinued one. Without these links, the part sits on the shelf and never shows up in search.

Many Partners, Many Formats

An aftermarket brand usually sells through several channels at once. Large auto parts retailers and distributors expect suppliers to send data in ACES and PIES format. Online marketplaces apply their own fitment and listing rules. Performance and accessory brands often share data through SEMA Data, and dealers still ask for spreadsheets or PDF catalogs. Every channel needs the same facts in a different layout, and with a few thousand SKUs manual updates fall behind.

What Bad Parts Data Costs

Wrong fitment means returns, restocking fees and one-star reviews. An incomplete or invalid data file can hold up a new product line at a retailer or get listings rejected. Missing interchange data loses sales without anyone noticing: the buyer just orders from the competitor whose number came up first. Track returns coded as "wrong part" for a quarter, and you will see what bad fitment costs your business.

ACES and PIES: The Aftermarket Data Standards

In North America, the Auto Care Association maintains two XML standards that most retailers, distributors and catalog providers use to exchange parts data. Once you know what each one covers, it is easier to check a PIM vendor's claims.

In April 2026, the Auto Care Association released ACES 5.0 and PIES 8.0 together with new versions of the reference databases. ACES 5.0 adds vehicle-specific digital assets to application records, several descriptions for one asset and manufacturer labels in multiple languages. Not every trading partner will switch at once, so for a while a supplier may have to send ACES 5.0 to one receiver and the older version to another.

ACES: Fitment Data

An ACES file is a list of applications. Each record connects one of your part numbers to a vehicle configuration from the VCdb, adds a part type from the PCdb and can include qualifiers such as "with rear disc brakes" or "from 03/2019 production". Because vehicles are referenced by standard IDs rather than free text, the receiver can load the data into its own catalog without guessing what "Civic 1.5T" means.

Example: From a Spreadsheet Row to an ACES Record

Here is how one rear brake pad set looks before and after conversion. The part number is made up, and the IDs are shown as placeholders: in a real file, each one comes from the current VCdb or PCdb release.

Most suppliers start with a fitment spreadsheet like this:

The spreadsheet is readable, but a receiver has to guess. Does "Civic" in your file match "Civic" in theirs? Is "Rear disc brakes only" a fitment condition or just a comment? The note matters here: in 2014 and 2015, the 1.8L Civic came with rear drums on the LX and HF and rear discs on the EX and EX-L, while the 2.4L Si always had rear discs and needs no note. In ACES, the first row becomes a record where every vehicle detail is a reference ID:

<App action="A" id="1">
<BaseVehicle id="[VCdb ID]"/>    <!-- 2014 Honda Civic -->
<EngineBase id="[VCdb ID]"/>     <!-- 1.8L L4 -->
<RearBrakeType id="[VCdb ID]"/>  <!-- Disc -->
<Qty>1</Qty>
<PartType id="[PCdb ID]"/>       <!-- Disc Brake Pad Set -->
<Position id="[PCdb ID]"/>       <!-- Rear -->
<Part>EB-4471</Part>
</App>

Each line answers one question. Three values come from you, and the rest are IDs from the Auto Care reference databases:

A complete file also has a header with your brand code and the VCdb version you used, plus a footer with the record count. The 2015 row for the 1.8L Civic becomes a record of the same shape. The Si row does not: in the spreadsheet, "Civic Si" sits in the model column, but in the VCdb, Si is a submodel of the Civic. Its record gets a SubModel element and no brake qualifier, and this kind of mapping has to be right before any file goes out. The receiver checks every ID against the same VCdb version, so a configuration that does not exist, such as a brake type never offered on that model, is flagged before the data reaches a store. Validation cannot tell you that a needed condition is missing, though: drop the brake note, and the record stays valid while the pads show up for drum-brake cars too. That check still depends on your catalog team. This is also why fitment has to be stored as structured data in a PIM: a file like this cannot be exported reliably from free-text notes.

PIES: Product Attributes, Packaging and Assets

A PIES file carries everything about the item itself: descriptions, physical and technical attributes, pricing, package dimensions and weights, hazardous material details, interchange numbers and links to images and documents. PIES 8.0 also adds fields for extended producer responsibility (EPR) packaging information support for several packages at one item pack level, and new options for digital assets, such as file hashing and sequencing of digital asset records.

VCdb, PCdb and Reference Data Licensing

Buyers often expect a PIM to "come with" fitment data. It doesn't. The reference databases come from the Auto Care Association through a separate annual subscription. The VCdb subscription, which you need for ACES, also includes the Qdb, PCdb and Brand Table, while PIES files require the PAdb, licensed on its own. The VCdb alone covers more than 175,000 vehicle applications across the US, Canada, Mexico and Latin America. Which of your parts fit which vehicles is still your job: that knowledge comes from your engineering and catalog teams.

How to Verify Standards Support

"ACES/PIES support" on a features page can mean anything from a full validated export to a CSV template with the right column names. Ask the vendor to run it on your data: import an existing ACES file, keep qualifiers and notes intact, validate against the current VCdb and export a file a receiver accepts. If standards output is built as a custom integration, agree in advance on the version, the validation rules and who maintains it when the standards change.

Core Capabilities of an Automotive PIM

Standards decide the format of the files you send out. Most of the daily work in a PIM for the automotive aftermarket happens before that: modeling parts, tracking changes and preparing data for each channel. If a vendor is weak in any of the seven areas below, your team will make up for it by hand.

A Relational Product Model

Parts data does not fit into one flat row. A PIM should let you set up product families, variants, kits and kit components as linked records. Then a brake kit knows which rotors and pads it contains, and shared attributes are inherited instead of typed again. With attribute sets by category, a spark plug gets heat range and thread size, and a control arm gets bushing type and ball joint details.

Fitment and Compatibility Management

Fitment should be stored as structured relationships between parts and vehicles, not as text in a description field. Then applications can be searched, filtered, edited in bulk and validated, and each one keeps its qualifiers, exclusions and approval status. Each change to an application should keep a record of who made it and when, so a wrong fitment can be traced back to its source.

Digital Assets and Installation Content

Parts buyers rely on more than a product photo. Exploded diagrams, dimension drawings, installation instructions, torque specifications, safety data sheets and 360° images help the customer confirm the part before ordering. The PIM should link each file to the right SKU, family or kit and track versions, so an outdated install guide does not stay live after a design change.

AI Enrichment With Human Approval

AI works well for first drafts of titles, marketing copy, bullet points and channel descriptions built from your attributes. On a large catalog, that removes most of the routine copywriting. Specifications, warnings, warranty terms and fitment still need a person to check and approve them before publishing.

Compliance Data: Prop 65 Warnings and Safety Documents

Many auto parts contain chemicals on California's Proposition 65 list. Depending on the exposure and the size of the business (the law applies to companies with 10 or more employees), products sold to California consumers may need a warning before purchase, and vehicle parts have their own approved warning wording. A PIM should store warning requirements, hazardous material classifications and safety data sheets as structured data, so the right warning appears on every channel by default and nobody has to remember to add it.

Dealer and Distributor Portals

Not every partner connects through a data feed. Many dealers and smaller distributors need a self-service portal where they can browse the current catalog, download images and spec sheets, and see their own pricing. With role-based access, you decide which partner sees which brands, regions and price lists.

Channel-Ready Data for E-commerce and Partners

Each channel has its own rules for titles, categories, required fields and image sizes. The PIM should keep one approved master record and adapt it for each destination: your own storefront, a Google Shopping feed or a file for a retail partner. Validation before publishing catches missing fields while fixing them still takes minutes. Native connectors to your main sales channels replace most of the manual export work.

Automotive PIM by Business Type

What you need from a PIM depends on where you sit in the aftermarket supply chain. Manufacturers, distributors and retailers start from different problems.

Parts Manufacturers and Brands

Manufacturers create the original data. They need solid fitment management, ACES and PIES output for retail and distribution partners, and a fast way to get new parts into every channel. Dealer portals and print-ready catalogs are often part of the same project.

Distributors

Distributors get data from dozens of brands, each in its own format and in varying condition. Their daily work is importing supplier files, bringing units and field names to one standard, filling gaps, mapping everything to one category tree and passing clean data on to their own customers.

Online Parts Retailers

Retailers need fitment that powers a year-make-model lookup, product pages with full specs and photos, and fast updates to their storefront and shopping feeds. For them, PIM is mainly about turning supplier files into product pages that answer the buyer's question: will it fit?

How to Choose Automotive PIM Software

Most automotive PIM vendors list fitment, ACES/PIES and channel syndication on their feature pages, so the list alone tells you little. To compare automotive PIM software properly, test it on one of your own product families. Use these questions in every demo:

• Can we load one of our existing ACES or PIES files, or our current fitment spreadsheet, and keep qualifiers, notes and exclusions?
• How are part-to-vehicle relationships stored, searched and bulk edited?
• How are interchanges and supersessions handled when a part number changes?
• Can kits, components and variants share attributes and assets without duplication?
• Which of our channels connect natively, and which need export files or custom integration work?
• What approval workflow and change history exist for specs, warnings and fitment?
• How do dealers and distributors access data, and can we control what each one sees?
• What is included in the price: users, onboarding, data migration, integration work and support?

Before a full migration, run a pilot on one product line. Audit the source data, map it to the new model, link assets, validate fitment and publish to one channel. A pilot like this shows whether the system handles your data and fits how your team works, and it leaves you with a template for the rest of the catalog.

Accurate Parts Data Sells More and Returns Less

In the automotive aftermarket, one missing qualifier or outdated part number can turn a sale into a return. When fitment, interchanges, assets and compliance data sit in one system with clear approval rules, every channel gets the same correct information. A new retailer or storefront then takes one more export instead of a rebuilt catalog.

For online sales, PIMinto connects natively to Shopify, BigCommerce, WooCommerce, Wix and Google Shopping. For everything else, the team builds custom integrations, from any ERP to ACES and PIES XML files for your trading partners. PIMinto does not ship with VCdb data or a built-in ACES and PIES export: these are set up as a project for each client, with the standard versions and validation rules your partners require.

Pricing is per company rather than per user: there is a free Starter plan, paid plans start at $300 per month, and onboarding is included in every plan.
