Choosing an ecommerce platform for a B2B business is a decision most owners make once and live with for years. Get it right and the platform quietly supports the way you actually sell — quotes, account-specific pricing, purchase orders, reorders. Get it wrong and you spend the next three years fighting the tool, paying for plugins that half-work, or explaining to buyers why they cannot see their negotiated prices.
The trouble is that most ecommerce advice is written for B2C — direct-to-consumer stores selling one item at a time to strangers with credit cards. B2B is a different animal. Your buyers are repeat accounts, they expect tiered pricing, they order in bulk, many pay on invoice rather than card, and the “add to cart, check out” flow is often just the last step of a relationship that started with a sales conversation.
This is a decision framework for the three realistic paths in 2026 — Shopify, WooCommerce, and a custom build — judged on what actually matters for B2B rather than on feature-list length.
Get Clear on Your Real B2B Requirements First
The platform question is unanswerable until you know how you sell.
Before comparing platforms, write down which of these your business genuinely needs — not which sound nice:
- Customer-specific pricing — do different accounts see different prices? This is the single most common B2B requirement and the one that separates the platforms most sharply.
- Gated catalogue — must buyers log in to see prices or products at all?
- Purchase orders and invoice payment — do accounts buy now and pay later, or is everything card-on-checkout?
- Volume and tiered pricing — automatic discounts at quantity breaks.
- Reorder flows — can a returning buyer repeat a past order in two clicks?
- Minimum order quantities and unit-of-measure rules (sold by the box, the pallet).
- Integration with your back office — inventory, accounting, and any existing ERP.
Rank these as must-have versus nice-to-have. A business whose only real need is a public catalogue with card checkout has a very different answer than one that needs per-account pricing and invoice terms. Most platform regret comes from skipping this step and picking on brand recognition instead of fit. This requirements list is also the backbone of a lean operation — see our minimal tech stack for B2B for how the storefront fits the wider system.
Shopify — Fast to Launch, Strong B2B Tier, Predictable Cost
Shopify is the low-friction choice, and its B2B capability is now serious.
Shopify has moved well beyond its D2C roots. Its B2B functionality — company accounts, customer-specific catalogues and price lists, net payment terms, and quantity rules — is built into the higher plans rather than bolted on. For a distributor that wants to be selling online in weeks rather than months, it is often the pragmatic answer.
Strengths:
- Speed to launch. A working store, hosted and secure, in days. No servers to manage, no security patches to chase.
- Reliability and maintenance. Shopify handles hosting, uptime, PCI compliance, and platform updates. You are renting a maintained system, not owning a codebase.
- Native B2B features on the right plan. Company profiles, per-account price lists, and payment terms exist without third-party plugins on Shopify’s B2B-capable tiers.
- App ecosystem for the gaps, though every app is a recurring cost and a dependency.
Trade-offs:
- Cost scales with plan and apps. The B2B features live on higher tiers, and each add-on app carries a monthly fee. Predictable, but not cheap at scale.
- Less deep customisation. You work within Shopify’s model. Highly unusual pricing logic or checkout flows can hit walls that require workarounds.
- Transaction fees unless you use Shopify’s own payments, which may not suit invoice-heavy B2B.
Shopify fits the business that values time-to-launch and low maintenance over total control, and whose B2B needs fall within the standard patterns of account pricing, terms, and reorders. Full product detail lives in Shopify’s own documentation.
WooCommerce — Maximum Flexibility on a WordPress Foundation
WooCommerce trades convenience for control and lower licensing cost.
WooCommerce is an open-source plugin that turns a WordPress site into a store. Because it is open and plugin-driven, almost any B2B requirement can be met — but you assemble and maintain the pieces yourself.
Strengths:
- No platform licensing fee. The core is free; you pay for hosting, plugins, and any development. For a business already on WordPress, it is a natural extension.
- Deep flexibility. B2B plugins add role-based pricing, gated catalogues, quote requests, and purchase-order checkout. If a standard plugin does not cover a need, a developer can build it, because you control the code.
- Content and SEO advantage. Sitting on WordPress makes it strong for content marketing, which matters for B2B discovery. Our guide to SEO for B2B services pairs naturally with a WooCommerce build.
Trade-offs:
- You own the maintenance. Hosting, security updates, plugin compatibility, and backups are your responsibility. A neglected WooCommerce site is a security liability.
- Plugin sprawl and conflicts. Meeting complex B2B needs can mean stacking several plugins, and plugins from different vendors do not always cooperate. Every plugin is an update to track.
- Performance depends on your hosting. Fast is achievable but not automatic; it depends on decent hosting and disciplined plugin choices.
WooCommerce suits the business that wants flexibility and lower licensing cost, already lives in the WordPress world, and has access to someone — internal or a reliable contractor — who can maintain it. It rewards technical ownership and punishes neglect.
Custom Build — Only When the Business Model Demands It
A custom platform is the right answer far less often than founders think.
Building bespoke ecommerce means commissioning software written specifically for your business. It offers total control and, in rare cases, is genuinely necessary. It is also the most expensive path by a wide margin, in both build and ongoing ownership.
When custom is actually justified:
- Your pricing, catalogue, or ordering logic is so unusual that no platform or plugin models it, and the workarounds would be worse than a build.
- You have deep integration requirements with proprietary internal systems that off-the-shelf connectors cannot reach.
- Ecommerce is the core of the business at a scale where platform fees and constraints materially limit you, and you have the engineering capacity to own software long-term.
The honest costs:
- High upfront cost and long timeline — months, not weeks, and a real budget.
- You own everything forever. Security, hosting, bug fixes, browser and payment-gateway changes, and every future feature are yours to fund. There is no vendor updating the platform for you.
- Key-person risk. A custom build is only as maintainable as your access to developers who understand it.
For the overwhelming majority of B2B small businesses, custom is the wrong choice — it consumes capital and attention that would return more if spent on sales and marketing. Choose it only when a platform genuinely cannot express your business model, not because custom feels more serious.
A Simple Decision Frame for 2026
Match the platform to how you sell and who maintains it.
- Choose Shopify if you want to launch fast, keep maintenance near zero, and your B2B needs (account pricing, terms, reorders) fit standard patterns. You are paying for time and reliability.
- Choose WooCommerce if you want flexibility and lower licensing cost, already run WordPress, value content and SEO, and have someone to maintain it. You are trading convenience for control.
- Choose custom only if your business model genuinely cannot be expressed on either, and you have the budget and engineering capacity to own software indefinitely.
Two cautions across all three:
- Do not over-buy. A platform with features you will never use is wasted money and added complexity. Buy for the requirements you actually ranked as must-have.
- Whatever you pick, the store still has to convert. Platform choice is upstream of the work that turns visitors into buyers — our guide to B2B website conversion applies regardless of which engine sits underneath.
Ecommerce platform choice for B2B is not about which tool is “best” in the abstract — it is about which one fits how you actually sell and who will keep it running. Write your real requirements down first, rank them honestly, and the answer usually becomes obvious: Shopify for speed and low maintenance, WooCommerce for flexibility and content strength, custom only when the business model truly leaves no other option.
The most expensive mistake is not picking the second-best platform. It is picking on brand recognition without matching to requirements, then spending years fighting a tool that was never built for the way your business works. Do the requirements exercise, and you will rarely regret the choice.
