The Anatomy of a Private Order Portal on Shopify Plus (2026 Guide)
A private order portal on Shopify Plus is a restricted-access storefront that wholesale buyers log into and experience as their own: their prices, their catalog, their payment terms, their order history. No public browsing. No retail pricing. No friction from a generic checkout not built for their purchasing workflow.
For manufacturers and distributors, a properly built portal eliminates phone orders, manual entry, and the operational overhead that comes from B2B buyers who cannot self-serve. For buyers, it means 24/7 access to correct pricing, instant reorder, and full account visibility without waiting for a sales rep.
This guide breaks down every component of a Shopify Plus private order portal: how each layer works, how to set it up, what the buyer experience looks like, and where the native features end and custom development begins.
This is the first question, and it deserves a direct answer.
On Shopify Plus: Native B2B features are fully available. Company accounts, unlimited price lists, unlimited custom catalogs, net payment terms, purchase order capture, and a dedicated buyer portal are all built into the platform. No third-party apps required for core functionality.
On standard Shopify plans (Basic, Shopify, Advanced): In 2026, Shopify expanded some foundational B2B features to all plans, including basic company profiles (limited number), up to three custom catalogs, and volume discounts. The full B2B feature set, including unlimited catalogs, direct catalog-to-company assignment, net payment terms enforced at checkout, buyer permissions, partial payments, and a complete self-service portal, remains Shopify Plus exclusive.
Third-party apps on standard plans can replicate some portal functionality: customer-tagged pricing, wholesale registration forms, and restricted catalog visibility. These are viable for small wholesale operations testing the channel before upgrading to Plus.
For any B2B manufacturer or distributor where wholesale is a meaningful revenue channel, Shopify Plus is the correct foundation. The native capabilities it provides replace the complexity of maintaining multiple apps, and the total cost is lower than the app stack required to approximate the same functionality.
The portal begins before a buyer sees a single product. Access control determines who can enter, what they can see, and how they authenticate.
Restricted storefront access. On Shopify Plus, the B2B portal can operate as a completely separate storefront with its own URL (yourstore.com/a/login/b2b or a custom subdomain), accessible only to invited users. The storefront is not indexed publicly and not accessible without valid credentials.
Company account-based access. Access is not granted to individuals, it is granted to companies. A buyer's login is linked to their company account, which determines what catalog they see and what pricing they have. If a buyer works for two companies, they need two separate logins.
Invitation-based onboarding. The standard flow for new buyers: you create a company and contact in the Shopify admin, assign their catalog and pricing, and send them an invitation email. The buyer sets their password and lands directly in their portal with the correct catalog and prices loaded on first login.
New buyer request flow. For inbound wholesale inquiries, a form on the public-facing site captures buyer information. Shopify Flow can automate the review and setup: when a tagged form submission arrives, Flow creates the company record, assigns a default catalog, and sends the invitation email. What was a manual multi-step admin task becomes a single approval action.
Passwordless login option. Shopify Plus supports passwordless authentication (login link sent by email) as an alternative to password-based credentials for buyers who prefer frictionless access.
Company accounts are the account management layer in Shopify B2B. Understanding how they are structured is critical for setting up a portal correctly.
Companies and locations. A company represents the buying organization. A location represents a specific purchasing entity within that company (a branch, warehouse, or subsidiary). Catalogs, price lists, and payment terms are all assigned at the location level, not the company level. A company with three locations can have different pricing and catalogs at each one.
Multi-user accounts. Each company location can have multiple buyer contacts, each with a defined role. Two roles are available natively: Ordering Only (can browse the catalog and place orders) and Location Admin (can also approve orders and manage the location's account). Additional role customization is available through custom development.
Sales rep assignment. You can assign internal team members as account managers for specific companies. This surfaces order history and account activity for your sales team without requiring them to ask operations.
Order history and account visibility. Every buyer has full visibility into their own order history, filtered by date, order number, and status. For manufacturers where buyers reorder frequently, this self-service history is the most-used feature in the portal, eliminating the "what was the status of my order from last month?" support inquiry.
This is the point where many B2B setups go wrong. Collections and catalogs look similar but serve entirely different purposes.
Collections group products for storefront navigation and merchandising. A collection called "Fasteners" contains all fastener products. Every buyer who can access the storefront can see any public collection. Collections do not control pricing.
B2B Catalogs control which products a specific company sees AND at what price. A catalog assigned to Company A shows 200 of your 500 SKUs at that company's negotiated pricing. A catalog assigned to Company B shows a different 300 SKUs at different pricing. Neither company sees the other's catalog or pricing.
Collections: Navigation grouping for all visitors
B2B Catalogs: Product and pricing assignment per company
Collections: No
B2B Catalogs: Yes (percentage adjustment, fixed overrides, volume tiers)
Collections: Public storefront
B2B Catalogs: Per company location
Collections: Not built-in
B2B Catalogs: Built-in per product in catalog
Collections: All customers
B2B Catalogs: Only assigned companies
Unlimited catalogs are Shopify Plus exclusive. Standard plans support up to three catalogs.
Shopify B2B's pricing architecture has three distinct layers that work together. Understanding the difference matters for setup and for avoiding misconfigurations that show buyers incorrect prices.
Catalog pricing (price lists). Sets the base price each company pays for each product. Configured as: a percentage adjustment off the standard retail price (e.g., Company A gets 30% off all products), or fixed price overrides for specific products or variants (e.g., Company A pays exactly $8.90 for SKU X regardless of the standard price).
Quantity rules. Controls how much a buyer can purchase. Minimum order quantity (must order at least 6 units), maximum order quantity (cannot order more than 144 units per order), and order increment rules (must order in multiples of 6) are all configurable per product within a catalog.
Volume pricing. Creates tiered unit pricing based on order quantity. A distributor who orders 50 units gets a lower per-unit price than one who orders 10 units, all within the same catalog and the same checkout without discount codes or manual quoting.
What It Controls: Who pays what base price
Set At: Catalog level, per product
Example: Company A sees SKU X at $8.90, Company B at $9.50
What It Controls: How much can be ordered
Set At: Per product in catalog
Example: Must buy 6+, in multiples of 6
What It Controls: How price changes with quantity
Set At: Per product in catalog
Example: 1-9 units at $10.00, 10-49 at $9.50, 50+ at $9.00
These three layers stack on top of each other and apply automatically when a buyer is logged in. The buyer sees their correct price without entering a code, without contacting a rep, and without any manual intervention from your team.
B2B buyers do not pay at checkout the way consumers do. The payment structure for wholesale accounts requires different checkout behavior.
Net payment terms. Shopify Plus enforces net payment terms natively. A buyer on Net 30 completes their order without entering payment details. The order is confirmed, fulfillment begins, and a payment reminder is issued 30 days after shipment. Net 15, Net 30, Net 60, and Net 90 are all supported. Payment terms are configured per company location.
Purchase order number capture. Buyers enter their internal PO number at checkout. The PO number flows through to the Shopify order record, your ERP, and all order notifications and invoices. This is a hard requirement for procurement-managed purchasing in most wholesale accounts.
Tax exemption management. B2B buyers with tax-exempt status have their exemption applied at the account level. Buyers do not need to upload certificates at each checkout. Tax exemptions are configured in the company account and enforced automatically.
Multiple shipping addresses. Buyers can select from all locations registered to their company account without re-entering addresses. A buyer at a company with five warehouse locations selects the correct delivery address from a dropdown.
Custom checkout forms. Shopify Functions enables custom fields in the B2B checkout: internal order notes, special delivery instructions, approval codes, or any field your operation requires. This replaced Shopify Scripts (end-of-life June 2026) and is the current architecture for all checkout customization.
What buyers see when they log in determines whether they use the portal or route around it. A portal with correct pricing but a frustrating interface does not reduce support volume. It generates it.
The buyer dashboard. The default landing page after login shows two sections: order history and shop. Order history provides a filterable view of all past orders for that location. The shop shows the catalog assigned to that location with the buyer's pricing already applied.
Product search and discovery. Buyers searching for a specific SKU, part number, or product description in a large catalog need search that works like B2C search. Shopify's native search handles standard catalogs. For operations with thousands of SKUs, complex attribute structures, or technical part number searches, Algolia provides the search experience that drives buyer adoption.
Quick reorder. The most frequently used feature in wholesale portals. Buyers view their order history, find the last order for a product or a full order, and reorder with a single action. Shopify Plus's native buyer portal supports order history reorder. For operations with heavy repeat ordering patterns, custom reorder features (CSV upload for bulk orders, saved carts, quick-add by SKU) extend the native capability.
Mobile access. B2B buyers place orders from warehouse floors, job sites, and trade shows. The buyer portal must work on mobile without compromising functionality. Shopify Plus storefronts are mobile-responsive by design. The B2B buyer portal renders on mobile with full order placement capability.
A private order portal without ERP integration is a data entry job. Orders placed by buyers in the portal must flow automatically to your fulfillment and accounting systems without manual re-entry.
Real-time order sync. Orders placed in the Shopify portal appear immediately in the ERP's fulfillment queue. No one on your operations team needs to manually enter the order. The buyer places the order; your warehouse receives the pick slip.
Inventory sync. Stock levels in your ERP update the portal in real time. Buyers see accurate availability. Overselling on out-of-stock items is prevented at the point of ordering. For manufacturers with complex multi-location inventory, inventory sync shows availability by warehouse or displays a combined total, depending on your configuration.
Pricing sync. Customer-specific pricing in your ERP syncs to Shopify's price lists. When contract terms change in your ERP, the buyer's price in the portal updates automatically. Pricing disputes caused by portal prices differing from invoiced prices are eliminated.
Customer account sync. New accounts approved in your ERP are created in Shopify. Account status changes and credit limit adjustments apply in both systems. A buyer whose account is placed on hold in the ERP cannot place new orders in the portal.
Uncap builds ERP integrations to Shopify Plus for NetSuite, SAP, Microsoft Dynamics, and Epicor as part of our B2B portal implementations. The Uncap Connect service handles the full integration architecture with real-time, bidirectional sync.
Shopify Flow handles the rule-based automation that makes the portal operational without manual admin work.
New buyer onboarding automation. When a wholesale inquiry form is submitted and tagged, Flow creates the company account, assigns a default catalog, and triggers the invitation email. What took 15 minutes of admin work per new account becomes an automated sequence.
Order routing. Custom order tags based on company account, order value, or product type route orders automatically to the correct fulfillment team or warehouse. Large orders above a threshold get a review tag before fulfillment confirmation.
Credit limit enforcement. Flow can trigger alerts or hold orders when a company account approaches or exceeds its credit limit, giving your finance team visibility before fulfillment is completed.
Reorder reminders. Automated communications via Klaviyo triggered by order history patterns (last order was 30 days ago, buyer normally orders monthly) prompt buyers to reorder before they run out of stock.
Navigate to Settings, then B2B. Activate the B2B feature. Confirm that new customer accounts are enabled for your storefront. Organize your product data with unique SKUs and clear variant structures before proceeding.
From the Shopify admin, navigate to Customers, then Companies, then Create Company. Enter the company name and primary contact information. You can create the company without a location, but you will not be able to assign a catalog or payment terms until a location is added.
Every company requires at least one location. Orders, catalogs, price lists, and payment terms are all assigned at the location level. For companies with multiple purchasing locations (different warehouses, branches, or subsidiaries), create a separate location for each.
Configure payment terms at the location level: select the appropriate net terms (Net 30, Net 60, etc.) or set the location to pay at checkout if no credit terms apply.
Add buyer contacts to the company location. Assign each contact a role: Ordering Only or Location Admin. Once saved, Shopify sends an invitation email to each contact with a link to set their password and access the portal.
Navigate to Products, then Catalogs, then Create Catalog. Add the products this company should see. For each product in the catalog, configure:
Assign the completed catalog to the company location.
Log in as a test buyer contact. Confirm that:
Fix any mapping issues before inviting real buyers.
Build the integration between Shopify Plus and your ERP before go-live. Define the five core data flows: order sync (Shopify to ERP), inventory sync (ERP to Shopify), pricing sync (ERP price lists to Shopify price lists), customer account sync (ERP accounts to Shopify companies), and fulfillment status sync (ERP fulfillment events back to Shopify order status). Test each flow with real data against your staging environment before switching buyers to the live portal.
For manufacturers operating across multiple countries or legal entities, the portal architecture needs to account for regional differences in pricing, catalogs, compliance, and currency.
Shopify Markets. The recommended approach for most international B2B operations. Shopify Markets allows catalog management with market-specific pricing, currency, and product availability from a single Shopify backend. A German distributor and a US distributor log in to the same portal but see market-specific pricing and currency automatically.
Expansion Stores. For operations with complete operational independence per region, separate legal entities, or significantly different product ranges across markets, Expansion Stores create fully separate Shopify environments under one Plus contract (up to 9 expansion stores are included). Each store has its own B2B portal, its own catalog, and its own admin.
Most mid-market B2B manufacturers serving international distributors use Shopify Markets. Expansion Stores are appropriate for enterprise operations with regulatory, legal, or structural reasons for complete separation.
Shopify Plus's native buyer portal handles the core self-service workflow. For B2B operations where buyers need more than order history and reordering, the native portal has limits.
Uncap's Self-Serve Portal extends the native Shopify B2B experience with capabilities built specifically for wholesale manufacturers and distributors:
The Self-Serve Portal sits natively inside your Shopify Plus storefront, fed by your ERP integration. It extends the platform rather than replacing it.
What is a Shopify private order portal?
A Shopify private order portal is a restricted-access storefront on Shopify Plus where approved wholesale buyers log in to access their company-specific pricing, product catalogs, and ordering workflow. Unlike a public Shopify store, the portal is not accessible without a login. Each buyer sees only their assigned catalog and pricing, not the pricing or products assigned to other accounts.
Do you need Shopify Plus for a B2B ordering portal?
For a complete native B2B portal with unlimited catalogs, net payment terms, purchase order capture, buyer role management, and a self-service account dashboard, yes. Shopify Plus is required. Standard Shopify plans (Basic, Shopify, Advanced) support limited B2B functionality: up to three catalogs and basic volume discounts. Third-party apps can extend standard plan B2B capabilities but require additional cost and configuration.
What is the difference between B2B catalogs and collections on Shopify?
Collections group products for storefront navigation and are visible to all customers. B2B catalogs control which products a specific company sees and at what price. A catalog assigned to one company shows different products at different prices than a catalog assigned to another company. Collections do not affect pricing. Catalogs define both product access and pricing for each wholesale account.
Can a Shopify B2B portal integrate with an ERP?
Yes. Shopify Plus integrates with ERP platforms including NetSuite, SAP, Microsoft Dynamics, Epicor, and Sage through API-based connectors. A properly built integration handles real-time order sync, inventory updates, pricing sync, customer account management, and fulfillment status tracking between the portal and the ERP. Neither system requires manual data entry once the integration is live.
How does pricing work in a Shopify B2B portal?
Shopify B2B pricing works across three configurable layers. Catalog pricing sets the base price each company pays through percentage adjustments or fixed price overrides per SKU. Quantity rules control minimum order quantities, maximum quantities, and order increments. Volume pricing creates tiered unit pricing that drops automatically as order quantity increases. All three layers apply simultaneously when a buyer is logged in, with no discount codes or manual quoting required.
Can multiple buyers from the same company use the same portal?
Yes. Company accounts support multiple buyer contacts, each with their own login and role. An Ordering Only contact can browse the catalog and place orders. A Location Admin can also approve orders and manage account settings. All contacts within a company location share the same catalog and pricing, but each has their own login and activity history.
How long does it take to build a Shopify B2B private order portal?
A standard B2B portal on Shopify Plus with ERP integration, custom pricing configuration, catalog setup, and buyer onboarding automation typically takes 6 to 12 weeks from project kickoff to go-live. Projects involving large catalog migrations, heavily customized ERP environments, or international multi-market configurations may require additional time.
What is the best way to handle new wholesale buyer applications?
The most efficient approach combines a public-facing wholesale application form with Shopify Flow automation for the review and onboarding sequence. When a completed form submission is tagged as approved, Flow creates the company account, assigns the appropriate catalog, sets payment terms, and sends the invitation email. This reduces the time-per-new-account from 15 or more minutes of manual admin work to a single approval action.
A private order portal is not a Shopify theme install. The complexity is in the pricing architecture, the ERP integration, the buyer onboarding workflow, and the account management layer that has to work correctly from the moment buyers start using it.
