Why Austin brands come to us for this
- Shopify Functions for variety-pack, case-pack and subscribe-and-save pricing that stops living in stacked discount apps.
- B2B on Shopify for the regional grocery and specialty-retail accounts Austin brands land early, with net terms and case minimums.
- Checkout UI extensions for cold-pack selection, gifting and post-purchase variety upsells on the same order.
- Subscription contract logic that survives a failed payment and a flavour swap without a support ticket.
- An honest Hydrogen recommendation — including the one where we tell a software founder not to build it.
The moment an Austin consumable brand crosses into real volume, the shape of the business changes faster than the store does. Subscription revenue arrives. A regional grocery chain places a standing order. A co-packer's lot codes need to reach the storefront. Suddenly there are three pricing realities — DTC, subscribe-and-save, and a wholesale price list — and they are being held together by a spreadsheet somebody maintains on Sunday nights.
Plus is where that stops being duct tape. Volume and bundle pricing move into Shopify Functions instead of three stacked discount apps. Wholesale moves onto B2B on Shopify with company profiles, case-pack minimums and net terms, on the same inventory as the direct store. Checkout gets extended with the things that actually raise AOV for a consumable: a variety-pack upsell, a cold-pack choice, a post-purchase add-on that does not require a second transaction.
On headless we are deliberately unhelpful to our own invoice. Austin founders come out of software more often than out of retail, which means Hydrogen gets asked about early and for the wrong reasons. We will build it — and we will tell you when a well-engineered Liquid theme will match it for a fifth of the ongoing engineering cost.
Local context
Where Austin brands actually outgrow standard Shopify
It is almost never traffic. In this metro the ceiling is pricing complexity and channel count. A supplement brand in the Round Rock corridor selling one-time, subscription, Amazon and regional wholesale needs four price realities on one catalogue, and standard Shopify will get you about two of them before the app stack starts fighting itself. The second trigger is capital: venture-backed founders in East Austin and around the Rainey Street corridor are usually reporting to a board that wants cohort economics by channel, which means the checkout and the subscription contract have to emit clean, attributable data rather than whatever three apps happen to write. Both problems are Functions, B2B and checkout extensibility problems — not front-end framework problems.
Scope
What Plus & Headless includes
The same standard of work we run for every client — applied to a Austin 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 Austin store
We do not work off a rate card. Every Austin 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.”

Verified client, 2026FAQ
Plus & Headless in Austin — your questions
That the performance case is usually already winnable in Liquid, and that Hydrogen adds a permanent front-end engineering line item. Headless earns its cost when you have genuine content-and-commerce complexity or an interactive configurator a theme cannot serve. For most Austin consumables brands, the money is better spent on subscription mechanics and measurement.
For most mid-market Austin brands, yes. Company profiles, assigned price lists, case-pack quantity rules, net terms and self-serve reordering cover the majority of what a natural-foods wholesale operation needs. Where it falls short is contract quoting and complex broker commission logic, which we handle with Functions or a light custom app.
As structured metafields, synced from whichever system holds the truth — usually the co-packer feed or your ERP. That makes them displayable on the PDP, queryable for recalls and usable in fulfilment routing. Consumables brands that leave lot data in a spreadsheet find out why it mattered during their first quality hold.
Checkout extensions, Functions at scale and native B2B need Plus. If your complexity is really just subscriptions and bundles, standard Shopify plus good engineering can carry you further than most agencies admit. We model the Plus fee against what you would genuinely unlock rather than assuming the upgrade.
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.
