Shopify Plus B2B Accelerator
B2B Protocol
The Shopify Plus B2B accelerator built by operators, not integrators.
B2B Protocol is our pre-built implementation framework for manufacturers and distributors migrating to Shopify Plus. It's not an app you install — it's a proven architecture of custom middleware, ERP integration, and buyer experience logic that we configure for your business. Every feature was built on real projects. Every module ships production-ready.
Shopify Plus has B2B features. You need B2B operations.
Shopify Plus ships with company accounts, catalogs, and price lists. That gets you 40% of the way. The other 60% — ERP-connected pricing, multi-segment routing, approval workflows, spend controls, automated reporting — requires custom development.
Most agencies scope that work from scratch every time. We don't. B2B Protocol is the 60% already built.
Account & access
Company user management
Add, manage, and assign roles across your organization. Granular permissions for ordering, approvals, and account administration.
Customer segment routing
Route buyers to isolated storefronts with their own catalog, pricing, and UX. Built as custom Shopify middleware — not theme-level logic.
Order approval workflows
Multi-level approval chains configurable per company tier. Managers review and approve before orders submit to your ERP.
Ordering
Quick order & bulk ordering
SKU-based rapid entry, CSV upload, paste-from-spreadsheet. Built for procurement teams who order the same 200 items every week.
Shopping lists & reorder
Create, save, and share shopping lists across teams. One-click reorder from past orders. Approval workflows on shared lists.
Pricing & catalogs
Real-time ERP pricing
Prices fetched live from your ERP and validated at Shopify checkout. No manual syncs. No price discrepancies between systems.
Customer-specific catalogs
Restrict product visibility per company, segment, contract, or region. Each account sees only what they should.
Fulfillment
Favorite store selector
Customers pick their preferred warehouse or branch location. Orders route there by default for fulfillment.
Inventory & lead times
Real-time stock levels by location. Estimated delivery dates. Backorder visibility and partial shipment handling.
Budget control
Corporate spend control
Gift cards as employee allowances. HR sets budgets per person, employees self-serve within their limit. Charge codes captured at checkout.
Automated expense reporting
Monthly spend reports per employee, department, or location. Auto-delivered to finance and HR contacts. No manual reconciliation.
Integration
ERP middleware
A custom private Shopify app that acts as the integration layer between your store and your ERP — orders, inventory, pricing, customer data. Works with ServiceCentre, SAP, Dynamics, Epicor, NetSuite.
Custom B2B account portal
Self-serve dashboard: order history, invoices, saved lists, team management, spend tracking. Everything your buyer needs without calling your sales team.
From legacy to live in weeks, not months.
Discovery & scoping
We audit your current systems, map your buyer segments, and identify which B2B Protocol modules your business needs. This is a paid engagement — not a free estimate.
Configure & integrate
We deploy the B2B Protocol modules on your Shopify Plus store and connect them to your ERP, PIM, and existing systems. Your pricing logic, catalog rules, and approval workflows are configured — not rebuilt from scratch.
Launch & train
Your team gets trained on managing B2B operations in Shopify. We handle 30 days of post-launch support. Your buyers start self-serving on day one.
Battle-tested on real B2B operations.
B2B Protocol was forged on the Husky Boutique implementation — a full migration from custom Laravel to Shopify Plus, serving four distinct buyer segments on a single platform: consumers, schools, multi-location enterprises, and corporate uniform programs with employee spend control.
Every module in B2B Protocol exists because a real client needed it, and we built it.
"Human After All's technical expertise and solution-oriented mindset have been strong throughout the project."
— Jérémie Gougoux, Director of Operations, Husky Boutique
Built for manufacturers and distributors who've outgrown their platform.
Distributors on legacy systems
You're running Magento, WooCommerce, or a homegrown solution. Your B2B buyers are ordering by phone because the website doesn't support their workflow. B2B Protocol gives you a production-ready Shopify Plus B2B storefront connected to your ERP.
Manufacturers selling direct and through dealers
You need different pricing, catalogs, and approval rules for different customer types — and it all has to run on one platform without duct tape. B2B Protocol handles the segmentation natively.
Hybrid B2B/B2C brands
You sell retail and wholesale from the same Shopify store. Online, pricing segmentation works. In-store, at trade shows, and across locations — B2B Protocol extends that logic everywhere, including Shopify POS.
Not a theme. Not a plugin. A proven architecture.
B2B Protocol is not an app you install from the Shopify App Store. It's a set of custom Shopify applications, middleware, and integration logic that we deploy and configure for your business.
Operator-led, not just developer-built.
Every module was designed by someone who's run B2B eCommerce at scale — not just implemented it. 18+ years of experience operating commerce for manufacturers and distributors, including delivering 52% B2B sales growth and four consecutive years of double-digit online growth in electrical distribution.
Custom middleware, not off-the-shelf connectors.
The core of B2B Protocol is a private Shopify app that handles the logic between your storefront and your back-office systems. This is what makes segment routing, real-time ERP pricing, and corporate spend control possible — not Shopify's native features alone.
Production-proven, not prototyped.
Every feature in B2B Protocol has been deployed, tested, and validated on live B2B operations. We don't sell roadmap items.
