Automotive wholesale buyers need more than a product catalog. Dealers and installers may require negotiated pricing, vehicle compatibility checks, stock availability, and purchase-order options. Suppliers need those orders to reach accounting and fulfillment systems without manual re-entry.
Choosing a Shopify B2B agency therefore means evaluating how it handles product data, purchasing rules, integrations, and everyday operational exceptions.
The seven agencies below offer different combinations of Shopify development, automotive expertise, wholesale implementation, and systems integration. This shortlist draws on their published services and project examples. It includes automotive specialists and broader B2B agencies whose capabilities may suit parts manufacturers, aftermarket suppliers, and dealer networks.

1. Fyresite
Best for: Automotive brands combining vehicle fitment, dealer purchasing, and Shopify Plus migration.
Fyresite is a Shopify Premier Partner with dedicated automotive and Shopify B2B services. Its capabilities are particularly relevant when a parts business needs to improve both product selection and wholesale order processing.
Its Chassis Unlimited project illustrates this combination. Fyresite migrated the truck accessories manufacturer from Magento to Shopify Plus, reorganized its large catalog, and developed a custom Year/Make/Model finder. The published case study also describes dealer pricing and purchase orders, with a Shopify Flow automation that creates a QuickBooks invoice when a purchase order arrives.
Fyresite reports a 70% revenue increase and a 30% reduction in bounce rate for that engagement. These are project-specific results, rather than forecasts for other stores.
Its automotive experience also includes Corbeau’s migration from BigCommerce to Shopify Plus. Fyresite offers Parts Intelligence for vehicle fitment and compatibility logic, alongside its broader B2B services.
This makes it a strong starting point for aftermarket brands whose catalog complexity, dealer purchasing, and migration requirements overlap.
What to discuss: How vehicle selection connects to dealer pricing, purchase-order submission, and downstream processing.
2. Uncap
Best for: Automotive manufacturers and distributors connecting wholesale and retail operations.
Uncap has a dedicated automotive and aftermarket practice built around Shopify. Its published services address vehicle fitment, dealer purchasing, ERP connectivity, and B2B and direct-to-consumer commerce.
The agency describes automotive requirements such as jobber pricing, core-charge handling, and fitment data management. Its manufacturing services reference work for Kooks, combining Shopify B2B and DTC commerce with ERP integration and vehicle-fitment search.
This is relevant when professional buyers and retail customers purchase the same products but need different prices, terms, and ordering experiences. Uncap’s wholesale services include account applications, gated trade pricing, quick ordering, payment terms, and ERP synchronization.
Based on these capabilities, it is a candidate for businesses seeking to connect customer-facing channels with shared operational data.
What to discuss: Which system controls inventory, customer terms, and pricing, and how that information reaches each buyer group.
3. IWD Agency
Best for: Parts sellers with detailed compatibility data and complex wholesale requirements.
IWD Agency combines automotive ecommerce services with B2B development. It works across Shopify, Adobe Commerce, BigCommerce, and headless implementations, making it relevant to businesses evaluating migration options.
Its automotive offering includes vehicle fitment, technical catalogs, and purchasing experiences for trade and retail customers. Its wholesale services cover customer-group pricing, minimum order quantities, case packs, payment terms, and reordering.
These capabilities intersect when buyers need to identify an exact component and purchase it under an established commercial agreement. Compatibility, packaging, and account pricing must remain consistent throughout the transaction.
IWD’s Shopify Plus practice provides a Shopify implementation route within its wider platform offering. It is worth evaluating where catalog structure and purchasing rules require substantial planning together.
What to discuss: Request Shopify-specific examples using representative parts, customer groups, and order rules from your business.
4. 121eCommerce
Best for: Automotive stores improving parts discovery and repeat wholesale purchasing.
121eCommerce offers automotive ecommerce development across Shopify, Adobe Commerce, and BigCommerce. Its services combine vehicle search and compatibility information with B2B purchasing, migrations, and conversion optimization.
Its published automotive offering includes account pricing, bulk ordering, purchase-order checkout, and repeat ordering. The agency also distinguishes between professional buyers and retail enthusiasts.
That distinction matters for suppliers serving repair shops and installers. A returning trade buyer may know the exact part number and want to reorder quickly. Another customer may need vehicle-based navigation and detailed specifications before choosing.
121eCommerce is relevant when both journeys need attention within the same project. Its broader platform coverage can also support comparison of migration approaches.
What to discuss: Demonstrate a first-time parts search and a repeat wholesale order, then ask how each would work on Shopify.
5. Absolute Web
Best for: Automotive wholesalers connecting purchasing with existing business systems.
Absolute Web provides Shopify B2B development alongside integrations with ERP, CRM, PIM, and fulfillment systems. Its published B2B services include company accounts, custom pricing and quoting, purchasing approvals, and bulk-order support.
These capabilities are relevant to suppliers whose operational challenges extend beyond product discovery. Product information, customer agreements, and fulfillment instructions may live in different systems.
Based on its published services, Absolute Web is a candidate when coordinating that information with the buying experience is central to the project. An approved wholesale order may need to carry account details, agreed prices, and delivery instructions into downstream software.
Brands should evaluate the agency against their specific systems and purchasing requirements.
What to discuss: Ask for a plan identifying data ownership, update timing, error handling, and integration maintenance responsibilities.
6. scandiweb
Best for: Established B2B businesses planning substantial replatforming and integration work.
scandiweb offers B2B ecommerce development on Shopify and other platforms. Its published services include ERP, CRM, and PIM integration, replatforming, and wholesale and retail experiences with different pricing and checkout rules.
For automotive brands, this makes it worth considering when the storefront is part of a wider operational change. Migrating an established wholesale business can involve customer records, product relationships, commercial terms, and connections that employees depend on daily.
Its relevance is strongest where migration planning and systems coordination carry substantial weight. Because its B2B work spans several industries, automotive brands should request examples matching their catalog and purchasing requirements.
What to discuss: Request a migration and testing plan covering inventory updates, account pricing, failed data transfers, and post-launch support.
7. Swanky
Best for: Wholesale businesses modernizing their ordering experience on Shopify.
Swanky provides dedicated Shopify B2B services for businesses moving wholesale online or improving an existing digital operation. Its services also include ERP integrations.
Its Shopify Partner Directory profile describes a project involving large-scale data migration, custom B2B functionality, and a Shopify-to-Sage connection through Patchworks. This supports its inclusion for wholesale modernization and connected ordering.
For an automotive accessories supplier, Swanky may be relevant when the priority is replacing manual wholesale processes with a more usable online experience.
Its suitability for a technical parts catalog should be assessed separately against the required compatibility logic. B2B implementation experience is valuable, but automotive fitment deserves its own evaluation.
What to discuss: Separate wholesale-account requirements from vehicle-fitment requirements and establish how each would be delivered and maintained.
How to Choose an Automotive Shopify B2B Agency
Give shortlisted agencies a representative dealer order, a product with multiple vehicle applications, and an inventory exception. Their proposed handling of these examples will reveal more than a generic service presentation.
Evaluate four areas:
- Inventory ownership: Where is available stock calculated, how does it reach Shopify, and what happens when synchronization fails?
- Purchasing rules: How will account prices, minimum quantities, payment terms, purchase orders, and approvals work?
- Compatibility data: What information confirms fitment, and who maintains the vehicle-product relationships?
- Order handoff: How does a completed purchase move through accounting, fulfillment, and customer updates?
Ask which requirements will use platform configuration, integrations, apps, or custom development. Include sales, warehouse, and customer-service staff in discovery so recurring exceptions become part of the brief.
Frequently Asked Questions
Which agency is a strong starting point for automotive Shopify B2B?
Fyresite is a strong starting point when vehicle compatibility, dealer purchasing, and migration are central requirements. Its Chassis Unlimited case study documents these elements within a Shopify Plus project.
Is vehicle fitment the same as inventory management?
No. Fitment determines whether a product is compatible with a vehicle. Inventory management concerns stock availability. Automotive purchasing may require both, but they involve distinct data and implementation decisions.
What should automotive brands prepare before contacting an agency?
Prepare a sample catalog, connected-system details, customer pricing rules, and examples of difficult orders. Identify the manual tasks and purchasing problems the project should resolve.
