A B2B portal is a private online store where your professional clients (distributors, installers, retailers, or wholesalers) log in with their user accounts, view their specific prices and conditions, and place orders without involving your sales team. If today those orders reach you via WhatsApp, email, phone, or an attached Excel file, the B2B portal is the piece that converts that chaos into an organized flow that goes directly into your ERP.
In this guide, we compare the three options we most frequently implement for industrial and distribution companies in Spain —Shopify B2B, WooCommerce, and Odoo— using criteria that truly matter in B2B e-commerce: per-client pricing, minimum order, deferred payment, ERP integration, and automation. We don’t sell a single platform: we are certified in all three and choose the one that fits each business.
What is a B2B portal and how does it differ from an online store?
A B2C online store displays the same catalog and price to everyone, charges instantly with a card, and that’s it. A B2B portal works the other way around: each client sees a different catalog and pricing, buys in professional quantities and formats, pays in 30 or 60 days, and reorders every week or month.
| Aspect | B2C Online Store | B2B Portal |
|---|---|---|
| Access | Open to any visitor | Private, with validated registration by your company |
| Prices | One for all, VAT included | Per-client or group pricing, VAT excluded |
| Quantities | Single units | Minimums, cases, multiples, and volume-based scaling |
| Payment | Card or Bizum instantly | Bank transfer, direct debit, or deferred payment based on credit |
| Repurchase | Occasional | Recurring: reorder in one click |
| Invoicing | Ticket or simplified invoice | Full invoice synchronized with the ERP |
That’s why setting up a B2B e-commerce isn’t just “putting up an online store with lower prices.” It’s about digitizing the commercial relationship you already have with your professional clients, with all its rules.
Signs that your company needs a B2B portal
For the manufacturers and distributors we work with, the trigger is almost never “we want to sell online.” It’s usually one of these symptoms:
- Orders arrive through five different channels and someone in administration manually enters them into the ERP, with the errors that implies.
- Pricing lives in Excel and each salesperson manages their own version, so two clients at the same level end up paying different prices.
- Your sales team spends more time checking stock and taking orders than acquiring new clients.
- Clients call to ask about the status of an order, an invoice, or a delivery note that they could check themselves.
- You want to grow your distributor network outside your area without proportionally increasing your sales and administrative staff.
If you recognize yourself in two or more of these, a B2B portal makes sense as an operational investment, not just a sales channel. The realistic goal isn’t to replace the salesperson, but to relieve them of the task of “taking orders” so they can focus on selling.
Essential features of a B2B portal
Before choosing a platform, it’s good to have a clear list of requirements. These are the functionalities that separate a useful B2B portal from an online store with a login:
1. Per-client pricing and catalogs
Each client or group (distributor, installer, key account) must see their specific pricing and, if necessary, only a portion of the catalog. This is the number one requirement and the one that most influences platform choice.
2. Quantity rules and volume discounts
Minimum order value, sales by case or multiples, and tiered pricing based on quantity. Without this, the portal generates orders that then need to be manually corrected.
3. Professional payment terms
Deferred payment at 30, 60, or 90 days based on each client’s risk, in addition to bank transfer or direct debit. B2B clients do not pay with a card at checkout.
4. Quick reorder and order by reference
Repeat a previous order, upload references from a list or CSV, and favorite lists. The professional buyer knows what they want: they don’t need to browse, they need speed.
5. Client area with documents
Order history, invoices, delivery notes, and shipping status available without calling anyone. This is what most reduces the administrative workload.
6. Bidirectional ERP integration
Stock, pricing, clients, and risk must come from the ERP; orders must return to the ERP without manual intervention. A B2B portal disconnected from the ERP only changes where someone re-types orders.
Shopify B2B vs WooCommerce B2B vs Odoo: A Comparison
All three platforms can function as a B2B portal, but they start from very different logics. Here is the summarized comparison we usually use to start a conversation with a client:
| Criterion | Shopify B2B | WooCommerce B2B | Odoo eCommerce B2B |
|---|---|---|---|
| B2B Features | Native (companies, catalogs, payment terms) | Via extensions | Native (pricing, client portal) |
| Individual client pricing | Complete only in Shopify Plus | Yes, with B2B extension | Yes, pricing assigned to each contact |
| ERP Integration | Via apps or custom connectors | Via API or custom connectors | It is the ERP itself: no synchronization needed |
| Design and logic flexibility | Medium, within SaaS limits | Very high (open source) | Medium-high |
| Technical maintenance | Low | Medium-high | Medium |
| Best fit for | Brands selling B2C and B2B with a simple catalog | Companies with complex pricing logic and a WordPress website | Manufacturers and distributors already using or planning to use Odoo |
Shopify B2B: quick to launch, with a limit worth knowing
Shopify includes native B2B features: company profiles with multiple locations, catalogs with custom pricing, quantity rules, volume discounts, and net payment terms. Its big advantage is the speed of implementation and low maintenance, especially if you already sell B2C on Shopify and want to open a professional channel within the same store.
The important nuance lies in the plan. According to Shopify’s official documentation on B2B features by plan, on Basic, Grow, and Advanced plans, you can only have up to 3 active B2B catalogs assigned to markets, while unlimited catalogs and direct pricing assignment to each company are reserved for Shopify Plus. In other words: if you have dozens of clients with individually negotiated prices, a true Shopify B2B means Shopify Plus, and that significantly changes the cost. We analyze this in more detail in our WooCommerce vs Shopify comparison.
WooCommerce B2B: maximum flexibility, in exchange for more architecture
WooCommerce does not natively include the concept of a wholesale client with their own pricing: B2B is built with extensions. WooCommerce itself offers a B2B pricing extension to create per-client group pricing, quantity discounts, and tax exemptions, and there are more comprehensive third-party alternatives for quotes, validated registration, or quick orders.
Its strength is that, being open source, you can model any commercial logic, no matter how unusual: family and client-specific pricing, prices based on region, technical catalogs with configurators. The cost is that you need a well-thought-out architecture (hosting, performance, plugin maintenance) and, above all, solid ERP integration. If you already have WordPress and a technical team or partner, it is often the option with the best control/cost ratio in the medium term.
Odoo B2B: the portal is an extension of your ERP
With Odoo, the approach changes: e-commerce and ERP are the same system. Pricing, stock, clients, and invoicing are already there, so there’s nothing to synchronize. The official Odoo documentation on B2B and B2C eCommerce details how to hide prices from anonymous visitors, grant portal access only to invited clients, assign pricing to each contact, and automatically generate invoices upon order confirmation.
It is the most natural option for manufacturers and distributors who already manage their operations in Odoo or are considering implementing it. Its limitation is on the front-end: the design and shopping experience are less flexible than in WooCommerce, which in B2B usually matters less than in B2C. If you are hesitating between the two, we recommend reading E-commerce with Odoo or WooCommerce: how to choose.
The piece almost no one explains: ERP integration and order automation
Most B2B e-commerce comparisons focus on the storefront. In our experience, the success of a B2B portal depends 20% on the platform and 80% on how it connects with the rest of the company. These are the integrations that have the most operational impact:
- Stock and pricing from the ERP to the portal, in real-time or in batches depending on volume, so the client never buys something that doesn’t exist at the wrong price.
- Orders from the portal to the ERP as already validated sales orders, ready for preparation and invoicing.
- Risk control: if a client exceeds their credit limit or has overdue invoices, the portal detects it before accepting the order.
- Automatic notifications for confirmation, shipping, and invoice availability, via email or WhatsApp.
When e-commerce and ERP are distinct systems (WooCommerce or Shopify with Odoo, for example), synchronization must be carefully designed to avoid saturating the API or the server. We explain this step-by-step in how to synchronize WooCommerce and Shopify with Odoo without blocking the server.
Beyond that integration, an automation layer with tools like n8n allows solving what no platform offers natively: converting an Excel file that a client still sends by email into a portal order, notifying the salesperson when an account hasn’t purchased for weeks, or automatically reminding the client of their usual reorder. You can see examples of these types of flows in our guide on WordPress and WooCommerce automation and, if your clients use WhatsApp, in AI agents on WhatsApp for businesses, which can take orders via that channel and directly upload them to the portal.
How to choose the platform for your B2B portal
Beyond the tables, the decision is usually resolved with four questions:
- Which ERP do you use or plan to use? If it’s Odoo, start by evaluating Odoo’s e-commerce. If it’s another ERP, the quality of its API is what matters.
- How many different pricing structures do you manage? With few group-based pricing structures, a standard Shopify plan might suffice. For client-by-client negotiated prices, consider Shopify Plus, WooCommerce, or Odoo.
- Do you also sell to the end consumer? If B2C and B2B coexist, Shopify and WooCommerce handle mixed stores well; for Odoo, it’s usually recommended to separate the websites.
- Who will maintain it? Without a technical team, the low maintenance of Shopify or Odoo is paramount; with a technical partner, WooCommerce gives you more flexibility.
Cost and timelines for a B2B portal
The cost of a B2B portal depends much more on ERP integration and the number of business rules than on design. The factors that most influence it are the platform and its plan (Shopify standard is not the same as Shopify Plus), the number of SKUs and pricing structures, the type of ERP integration, and additional automations. As a general guide, a portal built on an already organized ERP can be operational in a few weeks, whereas if the catalog, pricing, and client data need cleaning, the project will take longer. In how much an e-commerce costs in 2026 we break down the investment ranges by platform.
A practical tip: start with your top 20 or 30 recurring clients as a pilot. This will allow you to validate pricing, order flow, and integration with low risk before opening the portal to your entire distribution network.
Frequently asked questions about B2B portals
In practice, they are used synonymously. “B2B portal” emphasizes private access and the client area (orders, invoices, documents), while “B2B e-commerce” refers more broadly to selling online to businesses. A good B2B portal includes both.
Yes. Shopify and WooCommerce allow for a mixed store where professional clients see their specific prices upon logging in. In Odoo, it’s possible with a single site, although its documentation recommends separating B2B and B2C sites when both models coexist.
Most B2B features are, but with limits: on standard plans, you can have up to 3 active B2B catalogs, and direct pricing assignment to each company is only available on Shopify Plus. It’s advisable to review this point before choosing a plan.
Yes, through extensions that add group-based pricing, minimum order, quotes, and validated registration. It’s the most flexible option, but requires good technical architecture and solid ERP integration.
It’s not mandatory, but without an ERP, the portal loses much of its value: stock, pricing, and invoicing would end up being managed manually. If you don’t have an ERP yet, it’s a good time to consider an integrated solution like Odoo.
Conclusion: the B2B portal is an operations project, not just a website project
Shopify B2B, WooCommerce, and Odoo can all support a good B2B portal. The difference isn’t in the storefront, but in how well the platform fits your pricing, your ERP, and your way of working with professional clients. Choosing wisely at the beginning avoids an expensive migration two years later.
At Inprofit, we design B2B portals connected to ERPs and automated from start to finish, as an Odoo partner in Spain and a certified team in WooCommerce and Shopify.
