Why Sacramento brands come to us for this
- Company accounts for state agencies, districts and universities: PO checkout, tax exemption on file, net terms and quotes
- Grower reorder lists with volume breaks and quantity rules written as Shopify Functions, replacing stacked discount apps
- Allocation logic at checkout — per-member caps and tier access windows that hold on a release-day traffic spike
- Checkout extensibility for age and adult-signature messaging plus state shipping restrictions, shown before payment
- One catalogue and one inventory serving DTC, club, wholesale and institutional pricing without a parallel portal
The most valuable Plus work in this region rarely involves a headless rebuild. It involves getting a sales desk out of a spreadsheet. Sacramento's anchor employer is state government, and around it sits a whole layer of suppliers invoicing agencies, school districts, community colleges and university departments on purchase orders and net terms. Those orders arrive as emails and PDFs, get keyed in by hand, and the reorder that should take a buyer ninety seconds takes your team twenty minutes. Shopify B2B fixes the mechanics: company profiles, contract price lists, tax-exempt status, payment terms and a self-serve reorder history.
The second pattern is agricultural supply. Growers buy on a narrow seasonal window against a repeat list — the same nozzles, the same tape, the same amendments, ordered in a two-week rush before an application date. That behaviour rewards quantity rules, saved lists, volume-break pricing written as a Shopify Function instead of three stacked discount apps, and delivery logic that knows the difference between a ranch address off a county road and a yard in West Sacramento.
Then there is release day. A producer with an allocation programme does more revenue in a single hour in October than in the preceding six weeks, and that hour is where a stack made of apps fails. Per-customer purchase caps, tier-based access windows and member pricing belong in Functions running server-side at checkout, not in a script that races the customer. Checkout extensibility handles the rest — age and signature messaging, delivery-date choice, and the state-restriction notice appearing before payment rather than after.
Local context
Public-sector buyers and grower buyers break commerce in opposite directions
A district buying supplies and a grower buying inputs are both B2B, and almost nothing about them overlaps. The institutional buyer is constrained by procurement rules: they need a quote document with a number on it, a tax-exemption certificate on file, a PO reference carried through to the invoice, and net terms that will not be negotiated by a checkout page. The grower is constrained by weather: they need to buy fast, at volume, on a mobile signal that drops between Yolo and Sutter counties, with a delivery promise tied to an application window they cannot move. We build these as two distinct company-account experiences on one catalogue and one inventory — different price lists, different payment terms, different checkout requirements, different reorder logic — rather than pretending a single wholesale portal serves both. Getting that split right is usually what makes Plus worth it here, well before anyone needs Hydrogen.
Scope
What Plus & Headless includes
The same standard of work we run for every client — applied to a Sacramento 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 Sacramento store
We do not work off a rate card. Every Sacramento 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.”

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 Sacramento — your questions
Yes. On B2B you set payment terms per company so an approved account completes checkout with a PO reference and gets invoiced on net terms rather than paying by card. Tax-exempt status sits on the company profile so nobody has to remember to zero it manually. The part that needs care is your own approval process — we build a gate so a new company cannot self-serve onto terms before your finance team says yes.
Almost never. Shopify's checkout absorbs the spike; what falls over is usually your own stack — a queue app fighting a discount app, an inventory sync running on a five-minute cadence, or per-customer limits enforced in JavaScript that a determined buyer can bypass. Moving that logic into Functions and cleaning the app layer solves the problem far more reliably than a Hydrogen rebuild, and costs a fraction of it.
Price lists per company on one product. The distributor sees case pricing, the restaurant account sees its contract rate, the club member sees member pricing through a Function tied to their tag, and the public sees retail. Because it is one catalogue, your inventory is truthful across all four — which is the actual failure mode when producers run a separate wholesale site alongside a DTC one.
For the common cases, yes. A buyer builds a list, requests a quote, and your team approves or adjusts it into a document they can attach to a requisition. Complex or contract-bid work will still involve a person, and it should. The goal is not to eliminate your sales desk, it is to stop it re-keying the eighty percent of orders that are simply last year's list again.
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.
Through a documented middleware layer, never point-to-point. Every sync gets idempotency keys, retry with backoff, dead-letter handling and alerting into your Slack. You also get a daily reconciliation report so a silent failure cannot run for a week.
