About the App

Beyond the Year-Make-Model widget. Get an enterprise-level search infrastructure, where keyword search, filters, and fitment selection work in sync.

Convermax is not just a YMM selector. Our app manages complex catalogs with hundreds of thousands of SKUs, helping your customers to quickly find compatible parts and reducing returns, while also lowering the load on your support team.

We don’t sell a fitment database. Instead, our app pulls fitment data from ACES/PIES files, custom spreadsheets, PIM exports, or from one of sixteen fitment sources you already may have accounts with. It automatically indexes and applies to the products in your store. You can mix fitment data from different sources without overriding or duplicates. In addition, with our built-in Fitment Editor, your team can also create, extend, or refine your own fitment data.

Our search engine provides a range of industry-specific features.

  • My Garage

    Saves selected vehicles across sessions and inside customer accounts. The selected vehicle is also displayed in the cart and order details to minimize fulfillment errors.

  • Universal fitment logic

    The engine understands that certain products, such as oils, maintenance items, or merchandise, are universal and should not be restricted by vehicle selection.

  • Vehicle Landing Pages

    Automatically generated, fitment-specific URLs to support SEO and marketing campaigns.

  • Fitment-related Products

    Product suggestions are shown on the product page, even if the shopper hasn’t selected a vehicle yet.

  • and more.

It works with tools like Klaviyo, Yotpo, Affirm, and other e-commerce services.

Stores switching from generic search tools see immediate improvements in navigation, product discovery, and customer satisfaction.

It gives you control over fitment data. With Fitment Editor, you can build fitment data for your own brand or the boutique brand you distribute.
