Why Miami brands come to us for this
- Shopify Markets configured for real LatAm expansion: per-country pricing, catalogues, domains and hreflang
- Duties and import tax collected at checkout so a Bogotá or São Paulo buyer sees landed cost, not a carrier invoice
- B2B on Shopify for Doral distributors: company accounts, currency-specific price lists, case packs, net terms
- High-AOV checkout for Design District watches and jewelry — deposits, appointments, fraud-resistant flows
- Hydrogen only when a genuine multi-language content layer justifies the ongoing engineering cost
Miami is the reason Shopify Markets exists, functionally speaking. Brands here cross a border earlier than brands anywhere else in the country — a Wynwood label with a Colombian founder and a Brazilian audience is a completely ordinary business in this city and an exotic edge case in most others. The Plus features that matter here are therefore not the ones in the sales deck. They are Markets, duties collection at checkout, per-country catalogues and payment methods a buyer in Mexico City actually recognises.
The most expensive failure mode we see locally is the surprise carrier invoice. A Miami store sells to a buyer in Bogotá at what looks like a fair price, the parcel arrives, the carrier demands import duty, and the buyer refuses it. You now pay outbound shipping, return shipping, a chargeback fee, and you have burned a customer who told twelve people. Configuring duties and import tax so the buyer sees a landed cost before they commit is one of the highest-return pieces of engineering available to a store in this city.
There is a second Miami archetype that pushes past a standard theme: high-AOV goods out of the Design District. Watches and fine jewelry carry deposit flows, appointment booking, made-to-order lead times and a fraud profile that makes a normal checkout nervous. Shopify Functions and checkout UI extensions handle all of it natively. Headless is a separate question, and we will usually argue you out of it — but when a Miami brand genuinely needs a content-heavy multi-language front end at speed, Hydrogen on Oxygen is the honest answer.
Local context
Doral, Brickell and the Design District need three different Plus builds
Doral operates as a re-export and distribution corridor for goods moving south, so the Plus work there is B2B: company profiles, per-account price lists in different currencies, net terms, and quantity rules that reflect case packs rather than consumer units. Brickell's fintech-adjacent and capital-backed consumer brands tend to need clean multi-market economics and a checkout that survives an audit. The Design District's watch and jewelry trade needs deposit flows, appointment booking and fraud-safe high-ticket checkout. All three are Shopify Plus, and confusing one for another is how a Miami brand ends up paying for capability it will never switch on. We scope which of the three you are in the first workshop, not in month four.
Scope
What Plus & Headless includes
The same standard of work we run for every client — applied to a Miami 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 Miami store
We do not work off a rate card. Every Miami 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.
Get this scopedHow it runs
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.
Solution Design
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.”
Director of WholesaleFood & beverage brand, ~$22M/yr · Dallas, TX
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 Miami — your questions
Markets, in nearly every Miami case we have scoped. Separate stores mean duplicated catalogues, split inventory, three theme codebases to maintain and an SEO problem you created yourself. Markets gives you per-country pricing, currency, language, catalogue and domain routing from one admin. The exception is a genuinely different legal entity with a different assortment and its own fulfilment — that is a business decision, not a platform one.
We configure duty and import tax collection so the buyer pays landed cost upfront and the carrier is prepaid rather than chasing them on delivery. It requires correct HS codes and country of origin on your products, which is usually the real work — most catalogues we inherit have neither. Once it is set, refused deliveries and the chargebacks that follow drop sharply, which is where the money is.
For most mid-market distributors, yes. Company profiles with multiple buyers, price lists assigned per account and per currency, quantity rules for case packs, net payment terms and self-serve reordering cover the majority of the workflow. Where it stops is contract-level quoting with engineering configuration. We tell you which side of that line you are on during technical discovery rather than after the invoice.
Usually not, and we will say so. A well-built Liquid theme reaches sub-two-second LCP and costs far less to run. Headless earns its keep when you have a heavy editorial or content layer across multiple languages, interactive product configuration, or a front-end framework requirement Liquid genuinely cannot serve. Multi-language alone is not a reason — Markets handles that inside a theme.
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.
