Trusted by manufacturers and retailers selling automotive parts on Shopify
Already have a site? SPT installs on your existing store.
Don't need the full build? The SPT app is available for installation on any existing Shopify store — add fitment search, catalog sync, PDP enrichment, and inventory management without re-platforming.
One toolkit, six jobs done right.
Whether we run your store or you install the app yourself, the same six modules do the work — each configurable on its own, all reading from the same source of truth.
YMM Fitment Search
Year-Make-Model dropdowns, a multi-vehicle garage, VIN lookup (where supported), and license-plate lookup (where supported), with in-stock and vendor-priority result sorting.
Learn moreCatalog Parts Sync
Push your catalog into Shopify products - Description, Specifications, Buyer's Guide, and Interchanges.
Learn morePDP Product Information
Fitment, attributes, specs, notes, and Buyer's Guide content on every product page, themed to match your store.
Learn more NewIn-Cart Fitment & Fulfillment Handoff
The shopper's selected vehicle follows them to checkout and to your fulfillment team. Ship the right part the first time.
Learn morePrice & Inventory Sync
Pull price and inventory updates from FTP/SFTP or email and auto-hide out-of-stock products.
Learn moreOrder Export
Route orders to Email, FTP/SFTP, or API destinations by brand or SKU pattern. Customize the format for what your warehouse, ERP, or 3PL expects.
Learn moreBring the data you already have.
SPT speaks three industry-standard parts-data formats. Pick the one that matches how you already operate today. Switch later without rebuilding your storefront.
ACES / PIES XML
The industry-standard XML formats from the AutoCare Association. ACES describes which vehicles each part fits; PIES describes the parts themselves. Send files to us and we'll parses, validate, and sync them with your store.
- · ACES 3.x and 4.x fitment
- · PIES 6.x and 7.x product information
- · Full + incremental updates
ShowMeTheParts
Connect your ShowMeTheParts account and SPT will sync the parts, vehicles, and fitment your store needs without maintaining an ACES/PIES feed of your own.
- · VIN + license-plate lookup
- · On-demand re-sync
CSV
A spreadsheet is enough to get started. If you have a CSV of parts, vehicles, and fitment, you have everything SPT needs to power YMM search, catalog sync, and PDP enrichment.
- · Combined or separate files
- · Configurable column mapping
- · Validation report on each upload
All three connect into the same configuration:your YMM widget, PDP blocks, and admin settings carry over if you switch sources later.
Stop refunding parts that didn't fit.
Generic Shopify search doesn't know which cataltyic converter fits a 2014 Silverado. SPT does, and it carries that knowledge from the search box, to the product page, to the cart, to the order your warehouse pulls. Fitment verified on the product page and the selected vehicle following the order means fewer returns, fewer chargebacks, and shoppers who trust your store the second time.
- 1 SearchShopper picks a vehicle. It's saved to their session.
- 2 Product pageFitment, Buyer's Guide, and notes render from the same data feed.
- 3 CartThe vehicle travels as line-item properties, visible in the cart and order summary.
- 4 FulfillmentYour team sees the exact vehicle on the order before pick and pack.

Been working with Standard Parts Toolkit for a few years now and couldn't be happier. Their fitment toolbar has been a game changer for us. Our customers appreciate the ease in finding the right parts for their vehicle. We've really appreciated how easy it is to work with SPT and how responsive they are. Definitely recommend!
