Best B2B Customer Portal Software (2026): Top 9 Compared

Corevist sells a buyer-facing self-service portal that sits on top of SAP. The vendor's stated architecture is a direct extension of the ERP rather than a separate commerce platform fed through middleware, and the published consequence is that pricing, availability, credit standing, order status and shipments are read from SAP at request time instead of from a replicated store.

The published plan structure describes the portal in terms of what a buyer can do. Essential covers full SAP order history, real-time shipment visibility, invoice and payment access, credit and account status, and saved or scheduled SAP reports. That is a post-order account portal: the buyer stops calling to ask where an order is or to request a copy invoice, but does not transact. Professional adds the transactional half, listing online ordering, customer-specific pricing, SAP availability checks, customer-specific catalogs, quick order and reorder, order confirmations and quote-to-order conversion. Enterprise adds touchless order processing, a custom interface, public catalog with guest checkout, multi-country rollouts and product information management integration as add-ons.

The vendor states that most customers go live in 30 to 90 days and that all plans include the SAP integration. Outside SAP, the architecture that makes the product distinctive does not apply.

WizShop is the buyer-facing module of the WizCommerce platform. The wider platform, including the WizOrder representative application and the artificial intelligence order intake that reads emailed purchase orders, is compared on the B2B ecommerce platforms page; this entry covers only the signed-in surface a trade customer uses without a representative present.

The vendor describes WizShop as a storefront configured per account rather than per visitor. Catalogs are assigned by account, group, region or contract, so a buyer sees only the products and prices attached to their account. Pricing rules attach at the same levels and resolve at sign-in, supporting contract rates, tiered and volume breaks and account-level discounts. New trade accounts can be held for approval before pricing becomes visible.

The self-service mechanics target repeat buying rather than discovery. Buyers search by part number, description or a photograph taken on a showroom floor, build large orders through a bulk order form, and reorder a past order in one action with pricing and case packs reapplied. Quotes convert directly into orders, and payment happens in the same flow by card, bank transfer, deposit or net terms. Stock levels are read from the connected enterprise resource planning system, and the vendor lists more than one hundred pre-built integrations with two-way synchronisation of customers, inventory, orders, products, invoices and payments.

Unilog sells the CX1 Platform, combining product content services with a family of commerce and portal products for distributors, manufacturers and specialty retailers. Separate material is published for plumbing, pipe valve and fitting, heating and cooling, industrial supply, safety and sanitation, electrical, construction materials, farm and ranch, and pharmaceutical and medical distribution.

The commerce line is divided by business model rather than by tier. CX1 Sigma is the platform for digital commerce at scale, bringing commerce, product content and automated agents together so a small team can keep a large catalog current and searchable. CX1 Essentials targets independent distributors and retailers with limited marketing and technical resources, starting with a searchable catalog and adding online ordering and connectivity to an enterprise resource planning or point of sale system as the business is ready. CX1 Showroom serves decorative plumbing, hardware and lighting showrooms, letting trade customers browse the assortment, compare finishes and save selections. CX1 SPEX Builder, included with Showroom, turns those selections into branded quotes, project catalogs and architectural submittals with line-level margin control.

The content argument is why a distributor would shortlist Unilog rather than a general platform: a portal is only as usable as the catalog behind it, and manufacturer data in these verticals is often incomplete. No pricing is published for any edition.

Liferay sells a digital experience platform with open-source roots, and customer portals are a documented solution pattern rather than a separate product. The vendor states that more than 1,200 organisations run on the platform, with a partner network of more than 360 firms delivering larger projects.

The portal material organises self-service into four groups: order and shipping, covering placing an order, processing a return and checking shipment status; service and warranty, covering service tickets, warranty claims and appointment scheduling; profile and payments, covering personal details, preferences and stored payment information; and secure documents, covering contracts and statements. Around those sit tailored search weighted by purchase history and profile, integrated chatbots with handover to a live representative, knowledge bases and user forums.

The commerce module extends the same portal into transactions: account-specific catalogs and pricing, approval workflows, customer-managed order tracking and returns, contract pricing and bulk discounts, volume ordering through a list or uploaded file, one-click and automatic reordering, and representative tools for acting on behalf of an account.

Rather than replacing the ticketing, ordering and learning systems a large organisation already runs, the platform fronts them behind single sign-on and role-based permissions, with a content management system that lets non-technical staff keep the portal current. That flexibility is a build, with no published pricing to bound it.

Salesforce sells customer self-service as an addition to Service Cloud, separating the portal meter from the underlying platform. Two portal licences are listed. Service Portal Login is priced per login and described as covering a 24-hour session. Service Portal Member is priced per member and described as covering unlimited sessions in the month. The vendor's own guidance is that a member licence suits a known and frequent user population, and a login licence an unknown or infrequent one.

The licences buy a personalised portal with a single prompt bar for search and chat, a unified view of chat and knowledge articles, and dynamic cards that surface service automations. The artificial intelligence help agent deploys across voice, web, portals, messaging and chat, can trigger workflows such as scheduling appointments and managing orders, and escalates with full context when a case needs a person. That agent is metered separately and per resolution rather than per seat.

This is a support and knowledge portal joined to a service record, not an ordering or invoicing portal. Suppliers whose buyers need catalogs, contract pricing or invoice payment will be evaluating a different part of the Salesforce estate, and a different licence line, on top of this one.

Power Pages is Microsoft's low-code website builder for external-facing business portals, and it reaches this category through its data layer rather than through commerce features. Customer, account and transaction data held in Dataverse, or in Dynamics 365 applications sitting on it, is exposed to signed-in external users through forms, lists and data grids without hand-writing the access layer.

The commercial model is the distinguishing feature. The authenticated users plan is $200 per website per month for 100 users, paid yearly, with content delivery network support and 2 GB of Dataverse database capacity plus 16 GB of file capacity. The anonymous users plan is $75 per website per month for 500 users, paid yearly, with smaller capacity. A free 30-day trial precedes either. Because the meter is the site plus an allowance rather than the named external account, a supplier adding trade customers does not cross a per-seat threshold with each one.

The build surface is a drag-and-drop design studio with themed styling, industry templates, security and governance tooling, and generative assistance for layouts, sitemaps and copy. Developers can drop to the underlying markup, stylesheets and scripts through an integrated editor, or use the command line tooling with Visual Studio Code. Everything a business-to-business ordering portal needs beyond data access is a development project here, not a setting.

Magentrix sells two portal products on one platform, one for channel partners and one for customers, and positions the customer product as a lower-cost alternative to Salesforce Experience Cloud. It connects to Salesforce or Microsoft Dynamics, with a narrower HubSpot integration covering company records, contact and company insights, contact activity, deals and prospects.

The scope is customer service and enablement rather than transactions. Essentials lists case management, ticket deflection, a knowledge base with help articles, training and playbooks through a learning management module, frequently asked questions and wikis, file sharing and events. Advanced adds gamification and incentives, micro sites, a storefront, account hierarchy organisation, a developer console and electronic signature. Unlimited adds unlimited storefronts, a developer sandbox and unlimited users, and is quoted rather than listed.

Ticket deflection is the mechanism the vendor leads with: when a customer starts a ticket, candidate answers from existing content are presented before submission. Around it sit self-registration, content sharing permissions driven by any profile field, role-based record sharing, automation for alerts and group membership, and a no-code theme builder.

Because the platform mirrors the connected schema rather than synchronising selected fields, the vendor's position is that an administrator can extend the portal when the underlying record system changes, without a vendor ticket. Account hierarchy support on Advanced matters for trade customers with parent and child entities.

Versapay sells accounts receivable automation, and the part of it that belongs in this category is the customer-facing invoicing and payment portal.

The documented architecture is two connected portals over one record. The supplier portal carries invoice creation and delivery, payment rules for due dates, grace periods and recurring terms, delivery and engagement tracking, and collections activity. The customer portal gives buyers around-the-clock access to account status, outstanding balances and invoice and payment history, with branded electronic invoices and supporting documents attached.

On the payment side, buyers can pay with stored methods, pay several invoices at once, make partial payments, schedule future payments and enrol in automatic payment, and can update stored methods and notification preferences themselves. Accepted methods documented across the platform include bank transfer, credit card, virtual card and wire.

Collaboration is the differentiator the vendor emphasises. Disputes and short payments are raised in the portal with built-in commenting, so the reason for a withheld amount is captured against the invoice rather than reconstructed later from correspondence. No pricing is published at any level.

Billtrust approaches the customer portal from the order-to-cash side, on the premise that many business customers never visit a supplier's portal because their own accounts payable team works inside a portal of its own. The vendor documents automated invoice delivery into more than 260 such portals, with delivery status tracked in one place, alongside its own buyer-facing portal.

That branded Buyer Payment Portal is the self-service surface, described as showing buyers what they owe with guidance on what to pay, when and how, including where a discount is available. The invoicing product covers delivery across email, the buyer portal, accounts payable portals, the Peppol network, invoice clearance platforms and printed mail, with built-in compliance for electronic invoicing regulations and support for multiple languages and currencies. An email exception assistant surfaces bounced deliveries with recommended fixes and one-click resend.

On payments, the documented capability is policy control rather than a payment button. Rules are configurable by customer or segment, covering accepted methods, timing and how card processing fees are passed through. Methods include bank transfer, credit and virtual cards, direct debit and international modalities, with remittance captured back into the enterprise resource planning system. A digital lockbox automates virtual card processing. Nothing about price is published, and the model combines software with payment economics.
