Picking a B2B ecommerce platform is a different job from picking a storefront for a consumer brand. A DTC shop needs a fast checkout, good product pages and a decent email integration. A wholesale or distribution business needs all of that plus customer-specific price lists, quote requests, purchase orders, net payment terms, multiple buyers per account, and a reliable sync with an ERP that was probably installed before anyone on the team joined.
Most platform comparisons skip that last part and rank vendors by feature checklists. This guide is built around the questions that actually decide whether a B2B project succeeds: what your buyers do today, which system owns your pricing and inventory, and how much custom work you are prepared to fund and maintain.
What a B2B ecommerce platform has to do that a B2C platform does not
The core difference is that B2B buyers are accounts, not individuals. One company might have a purchasing manager who places orders, a finance contact who approves anything over a threshold, and three site managers who can browse but not check out. Each of them should see the same negotiated prices and the same payment terms.
That pushes a short list of requirements to the top:
- Company accounts with roles and permissions. Multiple users under one business, with approval rules and spending limits.
- Customer-specific pricing. Price lists per account or segment, tiered and volume pricing, contract pricing that expires.
- Flexible payment terms. Net 30/60/90, invoicing, purchase order numbers at checkout, and credit limits, alongside cards.
- Quotes and negotiation. A way for buyers to request a quote on a large cart and for sales reps to adjust and send it back.
- Fast reordering. Quick-order forms, SKU entry, CSV upload and "reorder last purchase." Repeat buyers do not want to browse.
- Catalog visibility controls. Some accounts should only see the products they are contracted for.
- ERP and PIM integration. Pricing, inventory, customer records and order status usually live in the ERP. The storefront has to read and write to it reliably.
If a platform cannot do the first three natively, you will be paying a developer to build them, and you will keep paying every time the platform updates.
The main B2B ecommerce platform options
The market splits roughly into three groups: SaaS platforms that added B2B features to a strong consumer core, platforms built for B2B from day one, and enterprise or headless suites aimed at large catalogs and complex organizations.
SaaS platforms with native B2B features
Shopify Plus (B2B on Shopify). Shopify has moved B2B features into the core product for Plus merchants: company profiles with multiple locations, catalogs and price lists per company, payment terms, quantity rules and volume pricing, and draft orders that work as quotes. The big advantage is the ecosystem and the operational simplicity. Hosting, security and checkout performance are handled for you. The trade-off is that very complex pricing logic or deep ERP workflows still lean on apps or middleware. It is often the best fit for brands that sell both DTC and wholesale and want one admin for both.
BigCommerce B2B Edition. BigCommerce bundles a B2B layer (originally the BundleB2B product) with company accounts, buyer roles, quote management, shopping lists, invoice portals and sales rep "masquerade" so a rep can shop on behalf of a customer. It also supports multiple storefronts from one back office. Teams that outgrow Shopify's B2B limits but do not want a self-hosted stack often land here.
Platforms built for B2B
OroCommerce. Oro was designed for B2B and has its own CRM layer. It handles complex account hierarchies, multiple price lists per customer, request-for-quote workflows and workflow automation without heavy customization. It suits manufacturers and distributors with complicated customer structures, though it needs a capable implementation partner.
Adobe Commerce (formerly Magento Commerce). Adobe Commerce ships with a B2B module that covers company accounts, shared catalogs, quick order, requisition lists, quotes and payment on account. It is extremely flexible, which is both the selling point and the risk. Total cost of ownership is high once you add hosting, upgrades and agency retainers. If you are already on it, our guide to choosing a Magento development agency covers what good ongoing support looks like. If you are weighing a move off it, see the Magento to Shopify migration playbook.
Enterprise and headless suites
Salesforce Commerce Cloud (B2B Commerce), SAP Commerce Cloud and commercetools sit at the top end. They make sense when you have very large catalogs, many regions and currencies, and an existing investment in that vendor's CRM or ERP. They are usually implemented by systems integrators, and project budgets and timelines are much larger than on SaaS options. Headless setups give you full control of the front end but mean you own the front-end code, performance and hosting.
A practical way to compare platforms
Feature grids make every vendor look similar because every vendor ticks the same boxes. A better comparison runs your own scenarios through each shortlisted platform.
1. Map your buyer journeys first
Write down the three to five most common things customers do. For example:
- A repeat buyer reorders the same 40 SKUs every two weeks.
- A new account requests pricing on a large first order.
- A buyer at a multi-location customer orders for one site under that site's PO.
- A finance contact downloads invoices and pays an outstanding balance.
Ask each vendor (or their partner) to demo these exact flows with your data, not their sample store. You will learn more in an hour of that than in a week of reading feature pages.
2. Decide which system owns what
Before talking to vendors, settle where the source of truth lives for pricing, inventory, customer records, and order status. In most B2B businesses the ERP owns all four. The B2B ecommerce platform then needs a dependable integration, either a certified connector for your ERP or a middleware layer. Integration is the most common reason B2B projects run late, so get a named connector or a written integration scope in the proposal.
3. Test pricing complexity early
Take your three most complicated customers and try to model their pricing on each platform. Contract prices, tiered discounts, freight rules, customer-specific SKUs. If a platform needs custom code to express pricing you already sell at today, that is a long-term maintenance cost, not a one-off build.
4. Check the B2B checkout
The checkout is where many B2B sites lose orders. Buyers expect to enter a PO number, choose payment terms, split shipments across locations and see tax handled correctly for exemptions. Run a test order with each requirement and watch where it breaks.
What a B2B ecommerce platform really costs
License fees are the visible part of the bill. The full cost has four pieces:
- Platform subscription or license. SaaS platforms charge a monthly or annual fee, sometimes with a revenue-based component. Enterprise suites are typically quoted on gross merchandise value or order volume.
- Implementation. Design, build, data migration and integration. On SaaS this ranges from a modest project to a significant one depending on ERP work; on enterprise suites it is usually the largest line item.
- Apps, extensions and middleware. Every gap in native features gets filled with a paid app or connector, each with its own fee and update cycle.
- Ongoing development and support. Upgrades, bug fixes and new features. Self-hosted platforms carry hosting and security costs on top.
Vendor pricing changes often, so get current written quotes rather than relying on published rate cards. Then model whether the investment pays back. A simple approach is to estimate the margin on incremental online orders and the cost saved by moving manual orders (email, phone, fax) online, and compare that against the total annual cost of the platform. The break-even calculator is useful here: plug in the platform's fixed annual cost and your contribution margin per order to see how many online orders you need before it pays for itself.
B2B customers also tend to be worth far more over their lifetime than a typical consumer buyer, because they reorder for years. Running your average account through the LTV calculator gives you a better sense of what a small improvement in retention or reorder frequency is worth, and makes it easier to justify features like quick order and saved lists that drive repeat purchases.
Migration and implementation pitfalls
Most of the B2B replatforming problems we see fall into a handful of categories:
Underestimating data cleanup. Customer records, price lists and product data in a long-running ERP are rarely clean. Budget time to deduplicate accounts, normalize units of measure and fix product attributes before migration, not after launch.
Recreating every legacy workflow. Some old processes exist only because the previous system could not do better. Question each custom requirement before paying to rebuild it.
Forgetting the sales team. If reps are paid on orders and the website "steals" their accounts, they will quietly steer customers back to email. Give reps visibility into online orders, credit them appropriately and give them tools like quoting and shopping on behalf of customers.
Weak onboarding for buyers. Existing customers need invitations, login help and a reason to switch. A launch plan that includes account setup, a short guide and outreach from reps does more for adoption than any feature.
Ignoring SEO during the move. Public catalog pages can bring in new accounts through organic search. Keep URLs stable where possible, map redirects and decide which parts of the catalog should be indexable versus gated behind login. Our ecommerce developer guide covers how to scope a technical build so these details are not left to the last sprint.
Getting buyers to actually use the new platform
A B2B ecommerce platform only pays off if orders move online. Track the share of total orders placed through the site by account, and treat low adoption as a conversion problem.
Start with the basics. Measure how many invited buyers activate their account, how many of those place a first online order, and how many come back for a second. The conversion rate calculator helps you compare those step-by-step rates over time so you can see whether a change to onboarding or checkout made a difference.
Then fix friction. Many of the tactics in our ecommerce conversion rate optimization guide carry over to B2B: clear product data, fast search, visible stock levels and fewer checkout steps. For B2B in particular, prioritize:
- Search that understands SKUs, part numbers and customer-specific product codes.
- Saved lists and one-click reorder on the account dashboard.
- Real-time stock and lead-time information pulled from the ERP.
- Order history and invoice downloads that remove the need to email customer service.
Finally, design the site for the people who use it. Procurement staff and trade buyers want density and speed, not lifestyle imagery. If your current site was built for a consumer audience, the principles in our article on web design for B2B companies will help reshape the experience around how business buyers evaluate and purchase.
Acquiring new accounts through the platform
Once the platform is live, it can also become a channel for new business, not just a portal for existing customers. Open parts of the catalog to search engines, add a clear "apply for a trade account" flow, and use paid search for high-intent product and category terms. Tactics from PPC for ecommerce apply, though B2B campaigns usually optimize for account applications or quote requests rather than immediate purchases.
Because B2B sales cycles are longer, judge new-account campaigns on cost per acquired account and lifetime value rather than first-order revenue. The CAC calculator makes it easy to compare channels on that basis.
A short checklist before you sign
- Have shortlisted vendors demoed your real buyer journeys with your data?
- Is there a named, supported integration for your ERP, with a written scope?
- Can the platform model your three hardest customer price agreements without custom code?
- Does the checkout support POs, payment terms, credit limits and tax exemptions?
- Do you have current written quotes for license, implementation, apps and support?
- Is there a plan for sales team incentives and buyer onboarding?
- Are SEO redirects and indexable catalog pages part of the migration plan?
If you can answer yes to each of these, the choice between two or three good platforms usually comes down to fit with your team and your budget, and any of them will serve you well.
FAQ
What is a B2B ecommerce platform?
A B2B ecommerce platform is software that lets businesses sell online to other businesses. Beyond a standard online store, it supports company accounts with multiple users, customer-specific pricing, quotes, purchase orders, payment terms and integration with ERP systems.
Is Shopify good for B2B ecommerce?
Shopify Plus now includes native B2B features such as company profiles, price lists, payment terms and volume pricing, which makes it a strong choice for brands that sell both wholesale and direct to consumers. Very complex pricing rules or deep ERP workflows may still need apps or custom integration.
How long does it take to implement a B2B ecommerce platform?
It depends mostly on integration and data work. A SaaS build with a standard ERP connector can be a matter of a few months, while enterprise implementations with custom integrations and multiple regions often take considerably longer. Clean data and a clear integration scope are the biggest factors in staying on schedule.
What is the difference between B2B and B2C ecommerce platforms?
B2C platforms are built for individual shoppers paying by card at a single public price. B2B platforms add account hierarchies, negotiated pricing, approval workflows, invoicing and net terms, bulk ordering tools and tighter back-office integration to support repeat business purchasing.
