Why Boston brands come to us for this
- B2B on Shopify for university, hospital and lab buyers: company accounts, price lists, net terms, PO checkout
- Tax exemption held at company level so institutional orders stop needing a manual credit afterwards
- Shopify Functions for case-pack quantity rules, volume tiers and delivery logic that replace stacked apps
- Checkout extensions that validate ship day and transit time before a perishable order is accepted
- Hydrogen only where a real content layer justifies it — we argue most Boston brands out of it
Boston is the clearest B2B case in the country and most brands here are still answering it by email. A lab in Kendall Square, a hospital procurement team, a university department, an athletics program — none of them are paying with a personal card. They want a quote, a purchase order, net terms, an invoice addressed to the right cost centre, and a tax exemption certificate held on file so nobody has to reclaim it later. That workflow does not need a separate commerce platform. It needs B2B on Shopify Plus configured properly.
The consumer side of the same catalogue keeps running as it always did, which is the part brands find hard to believe. One product catalogue, one inventory pool, one admin. Company profiles carry their own price lists, their own payment terms and their own approved buyers, so a research group ordering forty units sees institutional pricing and a graduate student buying one does not. Quantity rules handle case packs. Shopify Functions handle the tiered pricing and the delivery logic that used to live in three stacked apps and a spreadsheet.
Then there is the checkout work that is specific to what this city ships. Perishable orders need ship-day selection and transit-time validation inside the checkout, not on a product page where a customer can ignore it. High-value technical hardware needs deposit and lead-time handling. Both are checkout UI extensions and Functions, both are upgrade-safe, and neither is a reason to go headless. Hydrogen earns its place for a genuinely content-heavy front end, and for most Boston brands it does not — we will say so before you spend the money, not after.
Local context
Procurement here is a checkout requirement, not an edge case
In most metros institutional selling is a side channel a brand grows into. In Greater Boston it arrives early and unbidden, because the density of universities, teaching hospitals and research institutes means a consumer brand can get a purchase order in its first year. That changes the Plus build materially: exemption certificates need somewhere to live at the company level, net terms need an approval path finance will accept, and the purchase-order number has to travel from checkout through to the invoice or accounts payable will simply not pay it. We also plan the rollout around the fiscal and academic calendar, because departmental budgets and the ordering that comes with them do not follow the retail year. Getting B2B live before the summer purchasing run, rather than during it, is worth more than any feature on the list.
Scope
What Plus & Headless includes
The same standard of work we run for every client — applied to a Boston 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 Boston store
We do not work off a rate card. Every Boston 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.

From kickoff to results
Technical Discovery
We map your systems, order flows and edge cases end to end, then document where data breaks today. Output is an architecture diagram you can hand to any engineer.

Native-versus-custom decision for every requirement, with cost and maintenance load attached. Plenty of requests get answered with a $0 native setting.
Build in Sprints
Two-week sprints in a dev store with a staged demo at the end of each. You see working software every fortnight, not a status deck.
Load & Failure Testing
Peak-traffic simulation, payment-failure paths, partial-sync recovery and a rollback plan. We break it in staging so BFCM doesn't break it live.
Launch & Enablement
Phased rollout, monitoring dashboards and training for ops and finance. Every custom component ships with a README and a named owner.

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 Boston — your questions
An approved company profile with named buyers, a price list attached to it, payment terms their finance office recognises, and a purchase-order field at checkout that persists onto the order and the invoice. The exemption certificate sits on the company record so the order is untaxed at source rather than credited back. Set up once, the same buyer reorders without you touching it.
Yes, and it is usually the same build as the institutional work with different price lists. Company profiles cover regional stockists, case-pack quantity rules stop somebody ordering three units at wholesale cost, and self-serve reordering removes the email loop entirely. Most brands we see running a separate wholesale site are maintaining two catalogues for no benefit.
Less than people expect. Shopify handles the traffic on any plan; what Plus buys you at peak is checkout extensibility, so you can put gifting, delivery choice and post-purchase offers inside the checkout where move-in and commencement AOV actually moves. If your reason for upgrading is capacity alone, we will tell you to save the money.
Almost never worth it for that reason alone. Deep spec filtering across a large SKU tree is a metafield and search architecture problem, and a well-built Liquid theme with a proper search app solves it at a fraction of the running cost. Headless becomes reasonable when you have a heavy editorial or documentation layer sitting alongside the catalogue, which is a different conversation.
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.
