For merchants comparing platforms
If you're standing up a new automotive parts store — or thinking about replatforming the one you've got — the first question isn't "which app?" It's "which platform?" Here's an honest comparison of Shopify + SPT against the three alternatives most parts merchants actually evaluate: a custom build, Adobe Commerce (Magento), and BigCommerce.
Three things that are very hard for any other option to match — including a custom build with unlimited engineering budget.
Ecosystem
8,000+ apps in the Shopify App Store, tens of thousands of certified agencies and Partners, and a global pool of developers and theme designers. Need a tax integration, a 3PL connector, a CRM, a fitment toolkit (hi 👋), a B2B portal? It already exists.
Modern tooling
Shopify Magic for content generation, Sidekick as your in-admin co-pilot, semantic search that understands intent rather than keywords, and Shop Pay — the highest-converting checkout in commerce. None of this requires a custom build.
Scale + ease
PCI Level 1, edge CDN, near-perfect uptime, and a managed platform that scales from 100 SKUs to 100,000+ without an engineering team. Online Store 2.0 lets your marketing team rearrange the storefront without filing a ticket.
Order-of-magnitude numbers, not promises. Your mileage varies — but if you're at a planning meeting and someone asks "what would it really take to launch on each of these?", this is the conversation.
| Dimension | Shopify + SPT | Custom build | Adobe Commerce (Magento) | BigCommerce |
|---|---|---|---|---|
| Time to launch | Days to weeks | 6–12+ months | 3–9 months | Days to weeks |
| Up-front cost | $0 – low | Six figures and up | Tens to hundreds of thousands | $0 – low |
| Hosting + scaling | Managed by Shopify | On you (and your team) | Self-managed or Adobe Commerce Cloud | Managed by BigCommerce |
| Security & PCI compliance | PCI Level 1 included | Your responsibility | Your responsibility (or Adobe Commerce Cloud) | PCI Level 1 included |
| Talent & agency pool | Largest in commerce | Generic dev market | Smaller, specialized, shrinking | Healthy but smaller than Shopify |
| App / extension marketplace | 8,000+ apps | Build or integrate | 4,000+ extensions | Hundreds of apps |
| Store editor & themes | OS 2.0 visual editor | Build your own CMS | Dev-heavy, limited GUI | Stencil + Page Builder |
| Checkout | Shop Pay — highest-converting checkout in commerce | Build or integrate (Stripe, Adyen, etc.) | Native checkout, often replaced | Built-in checkout |
| AI shopping tools | Shopify Magic, Sidekick, Semantic Search — built in | DIY (OpenAI, etc.) | Adobe Sensei | Limited native AI |
| Fitment-aware parts UX | Built in via SPT | Build it yourself | Plugin or custom | Plugin or custom |
| Ongoing dev team size | Often zero | Permanent in-house team | Specialized devs needed | Light |
| Vendor lock-in | Moderate (your catalog is yours; storefront is Shopify) | None | Moderate to high | Moderate |
Ranges reflect typical projects in the automotive parts vertical. Replatforming projects and headless setups bend these numbers in both directions.
We'd rather you pick the platform that actually wins for your business than win a demo and lose a year. A few scenarios where the answer is honestly something else:
If your business runs on negotiated price books, multi-tier approval workflows, and integrated ERP transactions per order, Adobe Commerce or NetSuite SuiteCommerce can have an edge. Shopify Plus is closing the gap fast, but the legacy enterprise B2B leaders still win some of these RFPs.
If your "product page" is actually a configurator with thousands of branching decisions, or your "checkout" routes through a quote workflow rather than a cart, a custom build (or a headless Shopify deployment with a bespoke front end) is still the right answer.
If you've already paid the integration tax on another platform and it's earning revenue, replatforming is rarely the win. The right move is usually to extend what works, not start over.
Where SPT fits in
Shopify gives you a world-class storefront platform. What it doesn't ship with is fitment search, ACES/PIES ingestion, in-cart vehicle handoff, or order-export plumbing tuned to the way parts merchants actually run. SPT adds exactly those things — without leaving the Shopify ecosystem that the rest of the comparison above is about.
One install per store. Picks up your data from ACES/PIES, ShowMeTheParts, or CSV. Configurable from the theme editor like any well-behaved Shopify app.
We'll run a short demo against a sample of your ACES/PIES file, ShowMeTheParts feed, or CSV so you can see real fitment results before you decide.
