We build unified B2B and DTC commerce on Shopify Plus with year, make, and model fitment, part-number and interchange lookups, dealer portals, company pricing, net terms, and real-time ERP integration with Epicor, Plex, QAD, SAP, and Infor. Operating since 2013, Uncap serves the Detroit region. Your ERP has history. Years, maybe decades, of customization built up around how your shop floor, your dealer network, and your accounts actually work, none of it documented anywhere except in the system itself. That's not unusual in Detroit. It's the norm. A commerce partner who's never seen a Prophet 21 instance this deeply modified is going to break something or, worse, quietly ignore it. Uncap is a Shopify B2B agency and Platinum Partner built for manufacturers, distributors, and wholesalers doing $2 million to $50 million in revenue, connecting Shopify to the ERP you already run instead of asking you to replace it. ## A City Built on Automotive Aftermarket and Decades of ERP Investment Detroit is the automotive aftermarket epicenter on Uncap's expansion list, and it's Uncap's strongest proof vertical for exactly that reason: dealer networks, jobber accounts, and fitment-driven parts distribution that grew up around one of the deepest manufacturing bases in the country. Heavy equipment and broader industrial parts distribution sit right alongside it, businesses that grew up supplying, and being supplied by, that same manufacturing base. Customers order by account, expect net terms, and call when a production line or a dealer counter needs a part today, not after a website checkout figures out who they are. Detroit's ERP installed base is part of what makes this city different from a metro building its industrial economy from scratch. Decades of manufacturing and distribution here mean Prophet 21 and similar systems are already deeply embedded in day-to-day operations, extended and customized well past whatever the vanilla installation looked like. That depth is an advantage when your commerce partner actually knows how to work with what's already there, and a liability when they don't. Search "web design company Detroit" and you'll find plenty of shops that build good-looking sites, including a few genuinely deep operations with real manufacturing case studies. But building a manufacturer a nice site is a different skill from connecting that site to the ERP actually running the business. Prophet 21, and the account hierarchy a real manufacturer or industrial distributor runs on sit outside that skill set, even for the deepest manufacturing portfolios. A well-designed site that can't see your inventory, your customer-specific pricing, or your credit terms isn't a commerce system, whatever it looks like on the surface. It's a brochure with a cart bolted on, and the reconciliation work it creates for your team outweighs whatever time it saved on the front end. ## The products Uncap works on two things at once for operators in Detroit: getting you live on Shopify with real B2B infrastructure, and making sure Shopify and your ERP are telling the same story in real time, years of customization and all. **Uncap Commerce** is where the actual build happens, a first launch on Shopify, a move off a legacy platform or a manual, spreadsheet-driven process, or merging a DTC and B2B channel that run separately today. Architecture, data migration, and ERP integration are all part of it, not just what the storefront looks like. [Uncap Connect](https://www.uncap.com/products/connect) is what a Detroit manufacturer or industrial distributor feels most. It maps to your ERP as it's actually configured today, not a vanilla installation that doesn't match reality, which in Detroit is closer to the norm than the exception. That includes Epicor's Prophet 21 (P21), one of the systems most deeply embedded in Detroit's manufacturing and industrial distribution base after years of extension and customization. Orders, pricing, inventory, and customer terms sync in real time, so your storefront never shows a price your ERP doesn't already know, and accounts requiring EDI (Electronic Data Interchange) for purchase orders and advance ship notices run through that same layer. [Uncap Quotes](https://www.uncap.com/products/quotes) takes on the request-for-quote work that heavy equipment and industrial parts distribution never really moves past. Quotes get built, sent, revised, and converted into Shopify orders inside the admin your reps already use, with approval hierarchies that match how your accounts order today. [Uncap Portal](https://www.uncap.com/products/portal) gives repeat dealer and distributor accounts their own private ordering door: reorder history, account-specific pricing, and quick reorder on the parts they buy every week, without the friction of a public storefront designed for one-off shoppers. [Uncap Garage](https://www.uncap.com/products/garage) is worth a specific look for any Detroit business selling automotive-adjacent parts by Year-Make-Model fitment rather than a flat SKU list. None of these are bolted onto a template. They're built to reflect how a manufacturer or industrial distributor actually sells: by account, by production schedule, and by relationship. ## Does Connecting an Old ERP to Shopify Risk Breaking It? No, not with the right integration approach. Uncap Connect reads from and writes to your ERP through the same data structures already in use, without altering core configuration or forcing a schema change. The sync layer adapts to how the ERP is actually set up today, custom fields and all, instead of assuming a vanilla installation and breaking on contact. ## Working With a Shopify Platinum Partner Who Won't Flatten Your ERP Uncap became a Shopify Platinum Partner in 2013 and has since completed more than 380 B2B commerce projects. The work typically runs in phases: mapping your ERP, including any customization built up over years, and your pricing structure first, building the storefront and B2B accounts second, then syncing the ERP and going live, with a sandbox environment standing between testing and cutover. The ERP itself is rarely the sticking point for a manufacturer or distributor already on Prophet 21. It's the account-specific pricing, the credit terms, and years of accumulated customization that a generic integration was never built to understand, and that's exactly the layer Uncap Connect handles. A parallel environment during cutover means your team keeps taking orders as usual while the online side comes up alongside it. ## Beyond Heavy Equipment Heavy equipment, industrial parts, and automotive-adjacent distribution put Detroit on Uncap's expansion list, but they aren't the only kind of business Uncap works with here. Uncap's [industry pages](https://www.uncap.com/industries) cover Auto Parts & Aftermarket, Building & Construction, Electrical & Electronics, Industrial Machinery, Janitorial & Safety, Medical & Dental, and more, each built on the same underlying approach: Shopify B2B infrastructure connected to the ERP the business already runs, whether that's Prophet 21, NetSuite, SAP, or something else entirely. If your Detroit business distributes electrical components, industrial machinery, or safety supply rather than heavy equipment parts, the same approach applies. A DTC playbook doesn't describe how Detroit's manufacturers and distributors buy commerce software either way. What they need is a partner who already gets dealer networks, bill of materials (BOM) complexity, back-order handling, and a sales team that still closes deals by walking a customer's shop floor. [Uncap's guide to ecommerce for manufacturers](https://www.uncap.com/post/ecommerce-for-manufacturers) has more detail on what this looks like once a manufacturer is actually online. ## First 90 Days, Customization and All The actual barrier for most Detroit manufacturers and distributors isn't wanting a better system. It's not knowing what the first real step looks like without disrupting a shop floor that's busy every single day, especially when years of customization sit inside the ERP already. - Discovery and data mapping. Uncap reviews what's already in your ERP, including any customization built up over years, your current pricing structure, your account hierarchy, and your SKU or BOM catalog, and maps what moves to Shopify and how. - Storefront and B2B account build. Company accounts, customer-specific price lists, and net payment terms get set up to mirror your existing account structure, not a generic B2C checkout. - ERP sync and testing. Uncap Connect goes live in a sandbox environment first, so pricing, inventory, and order flow are verified against real data before anything touches a live order. - Go-live and parallel support. Your team keeps working the way they already do while the online side comes online, with a real support relationship behind it, not a help desk ticket queue. None of this requires ripping out Prophet 21 or whatever system your business already runs on, customization and all. Uncap builds on top of it. ## Talk to Uncap About Your Detroit Business Detroit's manufacturing and industrial distribution economy runs on relationships and decades of ERP investment, and Uncap builds Shopify B2B commerce the same way: [Shopify B2B](https://www.shopify.com/b2b) infrastructure connected to the ERP you already run, not a template storefront that ignores how your accounts actually work. ## Frequently asked questions ### Can Uncap work with an ERP that's been heavily customized over the years? Yes, and in Detroit that's closer to the norm than the exception. Uncap Connect maps to your ERP as it's actually configured today rather than assuming a vanilla installation that doesn't match reality. ### Does Uncap have a local presence in Detroit? Uncap works with Detroit manufacturers and distributors through dedicated, field-facing relationships, the same model used across every metro Uncap serves. That means direct access to the team building your commerce and someone who has actually walked your shop floor, not a support ticket queue. ### What size manufacturers and distributors does Uncap work with in Detroit? Uncap works with manufacturers, distributors, and wholesalers doing $2 million to $50 million in revenue, the mid-market range that's usually too large for a template Shopify build and too small to justify a six-figure enterprise implementation. That range covers most of Detroit's independent manufacturing and industrial distribution businesses. ### Does Uncap only work with companies already on Shopify? No. Uncap works with manufacturers and distributors at every stage of the process, whether that's a first-time Shopify launch, a migration from a legacy platform, or an existing live store that needs ERP integration or B2B features. Uncap Commerce covers the build or migration, and Uncap Connect handles ERP integration once you're live. ### How long does a Shopify B2B build take for a manufacturer with a legacy ERP already in place? It mostly comes down to how heavily customized the ERP is, the SKU or BOM complexity, and how clean your existing pricing and account data already are. Most mid-market builds run through three stages instead of one long project: mapping, then storefront and account setup, then ERP sync and go-live. Uncap's team can scope a real timeline once they see your ERP and product catalog. ### Does Uncap work with automotive aftermarket dealer networks specifically? Yes. Dealer pricing tiers, jobber accounts, and any direct-to-shop channel can run on the same Shopify storefront, each seeing the pricing and terms tied to their specific relationship. For parts sold by Year-Make-Model fitment rather than a flat SKU list, Uncap Garage matches fitment automatically so a buyer only sees parts that actually fit their vehicle before it reaches a quote.
