Top Shopify Experts For Automotive And Replacement Parts Stores In 2026

Selling auto parts online depends on one thing above all: the buyer has to be confident the part fits. That means Year, Make and Model search, fitment data on every product, and catalogs that can run to hundreds of thousands of SKUs. Many aftermarket brands also sell to dealers and shops at different prices.

Shopify does not ship fitment search out of the box, so the agencies that do this well have built custom apps, metafield structures or vehicle lookups. Each Shopify expert below has a named automotive project verified on its own website.

If you also sell wholesale to dealers, our list of Shopify agencies for B2B and wholesale ecommerce is a useful companion.

Best Shopify Experts For Auto Parts Stores In 2026

1. Realm — Replacement Parts Stores Built By A Shopify-Only Team

Realm has been building websites since 2007 and has worked only on Shopify since 2012, which puts it among the earliest firms listed in the Shopify Experts directory. The Minnesota team has delivered more than 250 Shopify stores and Clutch named it a top Shopify agency every year from 2013 to 2019.

Automotive and mechanical replacement parts are one of the named focus areas of its B2B practice. Realm built the Shopify store for Fleet Wash Supply in Oklahoma City, which serves fleet operators, and its inventory filtering work for European Wine Resource shows the kind of custom product discovery parts catalogs need. Its migrations include merchants moving from Magento, BigCommerce and Volusion, the platforms many older parts stores still run on.

Custom apps, ERP and fulfillment integrations, SEO and marketing sit in the same senior team. Realm suits US parts sellers that want one partner for the build and the growth work after it.

2. Fyresite — Premier Partner Specializing In Automotive Fitment Builds

Fyresite is a Shopify Premier Partner in Tempe, Arizona, and describes itself as Arizona’s first and only Premier Partner.

For Chassis Unlimited it moved the business from Magento to Shopify Plus, built a custom Year Make Model fitment tool and set up B2B dealer pricing with QuickBooks purchase orders. Pages load 150 percent faster, revenue is up 70 percent and bounce rate fell 30 percent. For Corbeau, the seat maker, it moved from BigCommerce to Shopify Plus with a native Year Make Model seat bracket finder built on metafields and a custom app connecting to Alloy ERP.

Fyresite is one of the most proven automotive Shopify partners available.

3. CQL — Original Platinum Agency With Custom YMM Apps

CQL was established in 1995 in Grand Rapids, Michigan and is a Shopify Platinum agency, one of the original ten in the US by its own account.

The Seat Shop, which sells seat covers, came to CQL after a failed Shopify Plus migration. CQL rescued the project, built a custom Year Make Model app and integrated Shopify POS. The conversion rate doubled and the team saves hundreds of hours on site updates.

CQL suits parts sellers whose replatform has gone wrong and who need an experienced team to finish it.

4. Teifi Digital — Million-SKU Fitment Data For Parts Distributors

Teifi Digital is a Shopify Platinum Partner with dedicated distribution and B2B practices.

For Royal Distributing, a powersports and automotive parts distributor, Teifi built a Shopify store carrying more than one million SKUs and 1.27 million vehicle-to-SKU fitment links, with a persistent Year Make Model selector that follows the buyer through the store.

For distributors with catalogs at that scale, few Shopify partners have published comparable fitment work.

5. Evoluted — B Corp Premier Partner Behind Reg-Lookup Commerce

Evoluted is a Sheffield and London agency with 20 years in business, Shopify Premier Partner status and B Corp certification.

CarMats.co.uk uses a bespoke Shopify vehicle registration lookup built by Evoluted. It draws on third-party vehicle data so products do not need manual fitment mapping. The store has handled more than 1.4 million lookups and over £10 million in lifetime orders, with a 7.68 percent conversion rate in 2022.

For UK sellers, number plate lookup is often a better experience than Year Make Model, and Evoluted has proven it at scale.

6. magic42 — Retailer-Born Agency For Motorsport Parts Migrations

magic42 began as a retailer in 2000 and has worked as an agency from Birmingham since 2018.

Roger Clark Motorsport sells rally and motorsport parts to trade and retail buyers. magic42 moved it from a legacy bespoke platform to Shopify with a homepage vehicle part finder, fitment guides on product pages, Doofinder search and ShipperHQ shipping. Online sales doubled year on year.

How To Choose A Shopify Expert For An Auto Parts Store

How Will Fitment Search Work?

Ask whether the agency uses a custom app, a third-party fitment app or metafields, and how fitment data is imported and updated. Year Make Model in North America and number plate lookup in the UK are different builds, so match the approach to your market.

Where Does The Fitment Data Come From?

Many parts sellers use ACES and PIES data or a supplier feed. Confirm the agency can import and maintain it at your catalog size, and ask how long a full catalog update takes.

Can It Support Dealer And Shop Pricing?

Aftermarket brands often sell to installers and dealers at trade prices. Check how dealer accounts, tiered pricing and purchase orders will be handled alongside retail.

Will Search And Speed Hold Up At Scale?

Parts catalogs are large and buyers search by part number. Ask about search tooling, page speed with fitment filters applied, and what happens to performance as SKUs grow.

Has The Team Migrated A Parts Store Before?

Older parts stores often run on Magento or BigCommerce with years of SEO value in their URLs. A team that has migrated parts catalogs will plan redirects and fitment pages carefully.

Conclusion

Auto parts is one of the hardest categories to sell on Shopify well, because fitment has to be right on every page. The ten agencies above have each published automotive work, from Year Make Model tools to number plate lookups and million-SKU fitment catalogs.
