Scale · Los Angeles
Why Los Angeles brands come to us for this
- Purchase limits, bundles and set pricing written as Shopify Functions, not stacked apps
- Checkout UI extensions carrying delivery cutoffs that hold across three time zones
- Shopify Collabs and affiliate attribution wired to real revenue, not link clicks
- B2B on Shopify for the specialty retail accounts most LA brands still run by email
- Hydrogen when the performance or content case is genuinely real — and a straight no when it isn't
Plus is a different surface, not a bigger theme, and in Los Angeles the parts that matter are the ones that fire under pressure. Purchase limits that actually hold when 40,000 people hit a 400-unit release. Bundle pricing for a two-piece set written as a Function instead of stacked across three apps. Checkout UI extensions that surface a delivery promise a Santa Monica buyer and a Nashville buyer both believe.
Silicon Beach has made LA founders unusually comfortable with engineering vocabulary, which cuts both ways. We get asked for headless more often here than in any other market we work in, and most of the time the honest answer is no. A well-engineered Liquid theme clears sub-2s LCP for a fraction of the running cost. Hydrogen earns its budget when there is genuine content-and-commerce complexity, an interactive configurator, or a performance ceiling Liquid cannot reach — and we will show you the arithmetic either way.
Where LA brands do consistently need Plus-tier work is the seam between attention and operations. Wholesale to specialty retail on Melrose or Abbot Kinney running through B2B rather than a shared spreadsheet. Multi-market routing when a UK audience follows a US creator. Tour and event merch with inventory holds against dates. Those are Functions, B2B and Markets problems, and none of them are solved by another app.
Local context
Plus features that matter to a drop-driven brand
Most LA brands hit the Plus threshold because of spikes, not steady growth, and that changes which capabilities pay for themselves. Purchase limits and cart-level rules written as Shopify Functions stop one bot-assisted buyer clearing a release. Checkout UI extensions carry the delivery cutoff and the exchange policy into the highest-intent screen, which matters when the marine layer means your customer has no idea what a jacket is for. Shopify Collabs and clean affiliate attribution decide whether a creator partnership is measurable or a vibe. And because the entertainment merch category lives here, we build pre-order and tour-dated releases with real inventory logic instead of a coming-soon page and a Google Form.
Scope
What Plus & Headless includes
The same standard of work we run for every client — applied to a Los Angeles 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 Los Angeles store
We do not work off a rate card. Every Los Angeles 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.
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.”

Verified client, 2026FAQ
Plus & Headless in Los Angeles — your questions
Usually not. Headless adds significant build cost and permanent engineering overhead, and for a typical LA apparel or beauty catalogue a well-built Online Store 2.0 theme performs just as well. We model the cost against the specific ceiling you are hitting. If the case holds we build Hydrogen on Oxygen properly; if it does not, we say so before you spend the money.
Yes, with Shopify Functions applying cart and checkout-level purchase limits by variant, customer and order, plus queue-safe cart behaviour. It is not bot-proof — nothing is — but it moves the outcome from a handful of resellers taking a release to genuine customers getting it, which is what your community judges you on.
Considerably. Tour-dated pre-orders, inventory holds per release, ship-by dates surfaced in checkout and venue or region-specific allocation all need real logic behind them. This is a category with genuine depth in Los Angeles and it is routinely run on a default theme, which is why fulfilment complaints spike after every announcement.
For B2B on Shopify, yes. It gives you company profiles, per-account price lists, quantity rules and net terms on the same store and inventory as your DTC front end. For an LA brand selling into a dozen specialty retailers, that replaces a line sheet PDF, a spreadsheet and a lot of email at a lower cost than a separate wholesale platform.
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.
