# Best Shopify Year Make Model Apps Compared [2026 Guide]
If you sell auto parts, wheels, or any vehicle-specific products on Shopify, you already know the headache. A customer lands on your store, finds a part they like, orders it… and it doesn’t fit their vehicle. Now you’re eating the return shipping cost, dealing with a frustrated buyer, and watching your margins shrink.
That’s where Year-Make-Model (YMM) apps come in. They add a simple dropdown — pick your year, make, and model — and only show products that actually fit. Sounds straightforward, but picking the right app? That’s where things get complicated.
We’ve spent months testing the major Shopify fitment apps. Here’s what we found.
## Why You Actually Need a YMM App
Before we compare apps, let’s talk about why this matters beyond the obvious.
**Returns kill auto parts margins.** Industry data puts automotive ecommerce return rates at 20-30% when fitment isn’t verified at checkout. A good YMM app can cut that to under 5%. Do the math on your current return volume — that’s probably your ROI right there.
Beyond returns, there’s the UX angle. Customers who can search by their vehicle spend more time browsing and convert at higher rates. They trust your store more because it “speaks their language.”
## The Apps We Compared
We evaluated six popular YMM apps based on pricing, features, ease of setup, data management, and real merchant reviews. Here’s the lineup:
| App | Starting Price | Rating | Key Strength |
|—–|—————|——–|————-|
| VFitz (Aculogi) | Varies by plan | — | Commission-free, CSV-based |
| EasySearch | $14.99/mo | 4.6★ | Established, multi-category |
| Convermax | $19/mo | 4.9★ | Advanced search integration |
| C: Year Make Model | $14.99/mo | 4.8★ | ACES data, My Garage |
| PCFitment | Custom pricing | 4.7★ | SEMA integration |
| AutoFit AI | $9.99/mo | 4.3★ | AI-powered matching |
### VFitz by Aculogi
VFitz takes a different approach than most YMM apps. Instead of charging commission or per-lookup fees, it uses a flat monthly pricing model. You own your fitment data — upload it via CSV, manage mappings in the admin panel, and customize the dropdown appearance to match your theme.
**What stands out:** The commission-free model is rare in this space. If you’re doing high volume, the cost savings add up fast compared to apps that charge per transaction or per lookup. It also supports custom dropdown configurations beyond the standard Year-Make-Model, which is useful if you sell parts that need additional filtering (like trim level or engine type).
**Where it fits best:** Merchants who already have their fitment data organized (or are willing to build it) and want full control without recurring per-use fees. Check out [VFitz pricing plans](https://www.aculogi.com/pricing/) for specifics.
**Potential drawback:** Less pre-built data compared to apps with SEMA/ACES integrations — you’re building your database yourself or importing via CSV.
### EasySearch (Year Make Model)
EasySearch has been around longer than most competitors and it shows in the polish. It handles not just automotive but also marine, motorcycle, and even electronics categories. The widget is customizable and works well on product pages with a fitment verification badge.
**What stands out:** Multi-category support beyond just cars. If you sell boat parts AND car parts, EasySearch handles both. The fitment table on product pages is clean and informative.
**Where it fits best:** Stores selling across multiple vehicle categories that need a single solution.
**Potential drawback:** Monthly pricing starts reasonable but scales up with features. Some merchants report the initial data setup takes longer than expected.
### Convermax
Convermax consistently gets the highest ratings in the Shopify App Store, and for good reason. It combines YMM search with general product filtering, pulling fitment data from multiple sources — your CSV files, SEMA data feeds, or even your existing product tags.
**What stands out:** The search engine combines fitment with keyword search seamlessly. A customer can search “brake pads” and filter by their vehicle simultaneously. The integration with third-party services (Klaviyo, Affirm, etc.) is also strong.
**Where it fits best:** Larger stores with complex catalogs that need fitment plus advanced search capabilities.
**Potential drawback:** Higher price point. For smaller stores, the feature set might be overkill.
### C: Year Make Model Search
C:YMM has carved out a strong niche with features like “My Garage” (customers save their vehicles) and built-in ACES/EPIDs data support. The URL redirect feature is clever — it creates SEO-friendly URLs based on vehicle selections.
**What stands out:** My Garage feature improves repeat customer experience. ACES compatibility means you can import industry-standard fitment data without reformatting.
**Where it fits best:** Stores that want pre-built ACES fitment data and strong returning-customer features.
**Potential drawback:** The interface can feel overwhelming during initial setup. Some merchants mention a learning curve.
### PCFitment
PCFitment is the enterprise option. Custom pricing, direct SEMA integration, and white-glove setup support. They’ve been in the fitment space specifically for Shopify longer than most.
**What stands out:** If you have SEMA membership and want to pull fitment data directly, PCFitment makes it seamless. Their support team handles a lot of the initial configuration for you.
**Where it fits best:** Established businesses with SEMA data access that want a turnkey solution.
**Potential drawback:** Custom pricing means you need to contact sales. Not ideal if you want to just install and go.
### AutoFit AI
The newest entrant uses AI to help with fitment matching, which sounds great on paper. It attempts to auto-match products to vehicles based on your existing product data, reducing manual data entry.
**What stands out:** The AI matching concept could save hours of manual fitment data entry. Lower starting price than most competitors.
**Where it fits best:** New stores that don’t have fitment data built out yet and want help generating it.
**Potential drawback:** AI matching isn’t perfect — you’ll still need to verify and correct. Lower review count makes it harder to judge long-term reliability.
## How to Choose the Right One
Here’s our decision framework:
**Pick VFitz if:** You want commission-free pricing, already have your fitment data, and want full control over customization. [See VFitz documentation](https://www.aculogi.com/docs/) to evaluate the setup process.
**Pick EasySearch if:** You sell across multiple vehicle categories (cars, boats, bikes) and need one app for everything.
**Pick Convermax if:** You have a large catalog and need fitment search combined with powerful general product filtering.
**Pick C:YMM if:** You work with ACES fitment data and want the “My Garage” saved-vehicle feature for returning customers.
**Pick PCFitment if:** You have SEMA membership and want enterprise-level support with hands-on setup help.
**Pick AutoFit AI if:** You’re starting fresh without fitment data and want AI assistance building your database.
## The Fitment Data Question
Here’s what nobody tells you upfront: **the app is only as good as your data.** Every single one of these apps requires accurate fitment data to work properly. The differences are in how you get that data in:
– **CSV import** — Most flexible, works everywhere. You build and maintain your own database.
– **ACES/SEMA feeds** — Industry standard, but requires membership or data licensing.
– **Manual entry** — Fine for small catalogs, painful for large ones.
– **AI generation** — Promising but unproven at scale.
If you don’t have fitment data yet, budget time for this. It’s the unglamorous part of running an auto parts store, but it’s what makes everything else work.
## FAQ
**How much does a Shopify Year Make Model app cost?**
Pricing ranges from $9.99/month (AutoFit AI) to custom enterprise pricing (PCFitment). Most apps fall in the $14.99-$29.99/month range. VFitz offers commission-free flat pricing — [check current plans here](https://www.aculogi.com/pricing/).
**Can I switch YMM apps later?**
Yes, but it’s not painless. Your fitment data format may need converting. Export your data before switching and verify import compatibility with the new app.
**Do I need ACES data to use a fitment app?**
No. While ACES data is the industry standard, most apps support custom CSV imports with your own Year-Make-Model-Product mappings.
**Will a YMM app slow down my Shopify store?**
Minimal impact if the app is well-built. The dropdown loads asynchronously on most apps. Always test page speed after installation.
**Can I use a YMM app with my existing Shopify theme?**
Most YMM apps work with all Shopify themes. Some offer deeper customization than others — check theme compatibility before installing.
