The new standards are here. Is your platform ready?

ACES 5.0 and PIES 8.0 were released in 2026, and the industry has already started to adopt them. This is the practical, no-pitch version: what actually changed in the standards, how real parts businesses rebuilt their B2B commerce around fitment, and a way to tell if you’re next.

The standard moved. Staying a version behind is the risk.

ACES and PIES are the data standards the aftermarket runs on, ACES for fitment, PIES for the product. In 2026 the Auto Care Association released ACES 5.0 and PIES 8.0, major schema versions that rename fields, tighten validation, and change the reference databases. Nothing forces you to upgrade. But once your partners publish in the new schema and you’re still reading the old one, records quietly break, and a fitment record that looks right can be wrong.

The goal is not to give every aftermarket business the same storefront. It is to give each one a stronger starting point: fitment built into the architecture, existing systems connected, and the flexibility to evolve as standards, channels, and customer needs change.

What’s inside the playbook

Written for the people who own the decision, and the ones who sign off on it.

What actually changed in ACES 5.0 / PIES 8.0

A plain explainer, no pitch. What’s new, what it means whether you consume the data (distributor) or publish it (manufacturer), what breaks when the two sides fall out of sync, and what a migration actually looks like.

Real examples, stated honestly

How KW Parts runs fitment-driven B2B commerce across roughly 30 countries on a 4M+ part catalog, plus two more from the field: search across 8.6M SKUs, and the pricing-inventory-ERP stack behind a complex parts catalog. We say what each of the three proves, and where the evidence stops.

A framework to see if you’re next

The two buying situations, what turns a long-standing problem into a funded project, and a checklist you can run on your own operation. Plus an honest note on who doesn’t need any of this.

The accelerator, and a look inside it

A fitment-ready starting point for aftermarket B2B commerce from Virto Commerce and Reveation Labs. What’s handled up front, what’s configured per business, and why it’s a head start rather than a switch-on product, with a look inside the experience (vehicle selection, Best Fit / Possible Fit status, saved vehicles).
