Why Detroit brands come to us for this
- Native B2B company accounts, contract price lists and terms replacing the rep-and-spreadsheet quoting loop
- Checkout extensions capturing PO number, work-order reference and dock or liftgate requirements
- Shopify Functions for quantity breaks, case and pallet rules and freight thresholds on heavy items
- Shopify Markets configured for routine Ontario orders — CAD display, duties and Canadian delivery expectations
- Integration scoped to what your job-shop ERP genuinely needs to sync, not a full two-way mirror
Most Plus conversations in this metro should start with B2B, not headless. A Tier 2 machining or fastener business that has sold through reps and purchase orders for thirty years does not need a Hydrogen storefront. It needs company profiles, contract price lists per account, quantity break rules, payment terms, and a reorder screen a purchasing agent can work through in ninety seconds. All of that is native now, which is why the honest answer to 'should we go headless' is usually no, and we would rather say so early than build you something impressive that your customers never asked for.
Where Plus genuinely earns its place here is in logic that used to require three stacked apps. Shopify Functions carry volume tiers, pallet and case-quantity rules, freight thresholds for heavy or oversized items, and account-specific discounts server-side. Checkout UI extensions add the fields your buyers actually use — PO number, job or work-order reference, dock delivery notes, liftgate requirement — inside a checkout that stays upgrade-safe rather than frozen on legacy code.
Then there is the border. Detroit–Windsor is the busiest commercial freight crossing on the US–Canada border, and a supplier here often has Ontario customers who are simply routine business. Shopify Markets gives them CAD pricing, duty and tax handling and a Canadian delivery experience without cloning the store. Headless enters the picture only when there is a real reason — a configurator, a shared front end across two brands, or content infrastructure that already exists elsewhere — and we will show you the maintenance cost before you sign up for it.
Local context
Your purchase-order process is the spec
Selling to shops in Macomb, Oakland and Washtenaw counties means selling into a buying process that predates ecommerce by decades: an approved vendor list, a PO number that has to appear on every document, terms that are negotiated per account, and a receiving dock with rules of its own. The Plus build here is essentially a translation of that process into checkout and account structure — PO capture as a required checkout field, terms and credit limits per company, ship-to locations for a customer with three plants, and order history a purchasing agent can filter by part number rather than by order date. The second Detroit-specific input is the ERP or shop-floor system already running the business. Job-based manufacturing systems rarely speak Shopify natively, so we scope the integration around what actually has to sync — stock, lead time, pricing tiers, order writeback — instead of attempting a full two-way mirror that nobody in your office can support.
Scope
What Plus & Headless includes
The same standard of work we run for every client — applied to a Detroit brand’s realities.
Full service detailShopify Functions
Custom discount, delivery and payment-method logic written as Functions. Volume tiers, bundle pricing and B2B rules run server-side instead of via three stacked apps.
B2B on Shopify
Company profiles, price lists, payment terms, quantity rules and a self-serve reorder portal. Wholesale and DTC on one catalogue, one inventory, one admin.
Shopify Markets & Localisation
Multi-currency, multi-language, market-specific catalogues, domain routing and correct hreflang. Expansion without a store-per-country sprawl.
Headless Hydrogen Storefront
Hydrogen on Oxygen with the Storefront API, edge caching and streaming SSR. We build this only when the performance or content case is real, and we say so when it isn't.
ERP, PIM & 3PL Integration
NetSuite, Business Central, Akeneo or a 3PL wired in through a documented middleware layer with retry logic, error alerting and a reconciliation report.
Scoped and quoted for your Detroit store
We do not work off a rate card. Every Detroit engagement starts with a fixed statement of work — named deliverables, named dates, one number — written after we have looked at your store, not before. If a smaller first step would serve you better, we will say so.

Supplements (Subscription DTC)
~$4.2M/yr, 60% subscription revenue, 22 SKUs, US · Shopify Plus (Recharge, Klaviyo)
Monthly subscription churn hit 9.4% and the cancel flow was a single button on a hosted page nobody had touched in three years. Support processed 340 subscription changes a month by hand because customers could not do it themselves. The named constraint: no forced logins. The brand refused to gate account access behind a password reset, which ruled out every off-the-shelf portal.

Home Goods & Furniture
~$11M/yr, 2,300 SKUs, configurable upholstery, US · Shopify Plus + Hydrogen storefront (Oxygen)
Fabric, leg and size options turned 2,300 SKUs into more than 40,000 variant permutations, and the Liquid theme rendered a configurable PDP in 6.9 seconds on mobile. Collection filtering ran client-side, so 40% of shoppers left before the first product painted. The named constraint: the ERP stayed. It was the single source of truth for stock and lead times and was not up for replacement.

In their words
Clients on this work
Reorder time 20 min → 3 min
“We sell wholesale into about 400 accounts and were still taking reorders by email like it was 2009. They built the B2B catalog on Shopify with net-30 terms and per-account price lists, and moved our whole rep team onto it in one week. Average reorder went from roughly 20 minutes of back-and-forth to under three.”

Verified client, 2025LCP 4.1s → 1.3s
“A Hydrogen build plus a NetSuite sync that our own team had failed at twice. Inventory finally matches between the warehouse and the storefront, which sounds boring and is the most valuable thing anyone has done for us this year. LCP went from 4.1s to 1.3s. The honest part: the first six weeks felt slow and I genuinely wasn't sure we'd picked right — it only clicked once we moved to a standing Thursday call with the engineers instead of account-manager summaries.”

Plus & Headless in Detroit — your questions
Some will not, and the build should assume that. The ones who convert fastest are the repeat-line buyers ordering the same twelve part numbers monthly, because a reorder list beats retyping a PO. We usually keep an email or draft-order path open for the holdouts and let adoption happen account by account rather than mandating it and losing goodwill.
Yes. Each company gets its own catalog and price list, retail sees published pricing, and the product record and inventory pool stay singular. The important design decision is what a logged-out visitor sees — some brands here publish list price, others hide trade pricing entirely — and we set that deliberately because it affects both your channel relationships and your Shopping feed.
It handles it once the rules are explicit. Weight and dimension data has to be real, oversized items need their own shipping profiles, and freight-quote or call-for-quote paths belong in Functions and checkout logic rather than in a note field. LTL for a pallet of tooling is a solved problem; it is only painful when the catalog data was never populated properly.
No, and running two stores usually costs you more than it saves. Shopify Markets handles CAD pricing, duty and tax collection and market-specific content from the same admin. What does need attention is your commercial invoice data and HS codes, because a Windsor customer waiting on customs for a part they could have driven over to collect is a support problem you only get once.
Usually not. A well-built Liquid theme hits sub-2s LCP and costs a fraction to run. Headless earns its keep when you need a custom front-end framework, a heavy CMS-driven content layer, or interactive product configuration Liquid cannot serve. We will talk you out of it if the numbers don't hold.
No. Shopify has retired it in favour of checkout extensibility, and anything still running on it is on borrowed time. We migrate custom checkout logic into checkout UI extensions and Functions, which survive platform upgrades instead of blocking them.
For most mid-market brands, yes. Company accounts, per-company price lists, net payment terms and quantity rules cover the majority of wholesale workflows natively. Where it falls short is complex quoting and contract pricing, which we handle with Functions or a light custom app.
