How to Build a B2B Marketplace (2026 Playbook)
To build a B2B marketplace, you combine two layers on top of an online store: a multi-vendor layer for onboarding suppliers, splitting orders, and paying them out, and a B2B trading layer for wholesale pricing, net terms, minimum orders, and quotes. On Shopify, a multi-vendor app plus Shopify's own B2B tools covers most of it in days.
That two-layer split is the part most build guides skip. They tell you to pick a niche and recruit suppliers, which is true of any marketplace. The wholesale-specific plumbing is what actually makes it B2B, and it's where projects stall.
If you're still deciding whether a marketplace is the right model, start with what a B2B marketplace is and the top B2B marketplaces already operating. If you want the generic seller mechanics that every marketplace shares, the build a multi-vendor marketplace guide covers onboarding, commissions, and payouts in depth. This page is the wholesale-specific version: the mechanics a Faire or an Ankorstore has that a consumer marketplace doesn't.
The demand is real and it's moving online. In McKinsey's global B2B Pulse survey, 39% of B2B buyers now place orders over $500,000 through self-serve ecommerce or remote channels, up from 28% two years earlier. Six-figure orders used to demand a sales rep and a handshake. Now buyers want to place them from a screen, on their own terms, which is exactly what a B2B marketplace has to support.
What makes building a B2B marketplace different
A consumer marketplace and a B2B marketplace share the same skeleton: many sellers, one storefront, an operator taking a cut. The difference lives at the checkout. Business buyers order by the case or pallet, pay on invoice weeks later, and expect a price negotiated for their account rather than the sticker on the page.
Here's the honest breakdown of who handles each B2B mechanic when you build on Shopify. Some of it is your marketplace app, some of it is Shopify's own B2B feature set, and one piece still needs a separate tool.
| B2B mechanic | Handled by | What to know |
|---|---|---|
| Wholesale supplier onboarding + catalog sync | Multi-vendor app (Garnet) | Suppliers connect a Shopify, WooCommerce, or PrestaShop store, or upload by CSV |
| Order splitting, commission, and payouts | Multi-vendor app (Garnet) | One buyer payment splits across suppliers; you keep a cut; payouts run on a schedule |
| Company accounts and buyer logins | Shopify B2B | Groups several buyers under one business, with roles and permissions |
| Customer-specific and tiered price lists | Shopify B2B | Native and unlimited on Plus; capped at three catalogs on standard plans |
| Minimum order quantities and increments | Shopify B2B | Quantity rules attach to B2B catalogs |
| Net terms (Net 15/30/60) and deposits | Shopify B2B | Deferred payment at the B2B checkout |
| Tax-exempt purchasing | Shopify B2B | Set per company account |
| Quote requests (RFQ) | Extra app | No native RFQ portal; use draft orders or a dedicated quote app |
Two things to flag before you build around this table. First, Shopify's B2B suite is designed for a single-merchant wholesale store, so layering per-company price lists across dozens of independent suppliers can get complex fast, and the deepest features are strongest on Shopify Plus. Second, you can create a B2B marketplace three ways, and only the app route below assumes you already have (or want) a Shopify store. The six steps that follow map to that route.
Step 1: Pick your B2B marketplace model
Before any software, decide what kind of B2B marketplace you're running, because it sets who your suppliers are and how you make money. This is really a B2B marketplace strategy decision, model, monetization, and which side of the market to win first, made before you touch a tool. Most new builds fall into one of three shapes.
- A distributor digitizing its supplier catalog, turning a spreadsheet-and-phone operation into a self-serve ordering channel for retail buyers.
- A brand or platform aggregating complementary makers, so one buyer can order across many suppliers in a single basket.
- A trade association or group pooling its members into a shared, invite-only marketplace.
All three are managed, private marketplaces: you control who joins, you set the commission, and you own the buyer relationship rather than renting it from one of the public B2B wholesale marketplaces like Faire or Alibaba. That ownership is the whole reason to build instead of joining, and it's the theme the rest of this guide keeps coming back to.
Step 2: Onboard and vet your wholesale suppliers
In B2B, supplier quality matters more than supplier count. A retail buyer placing a five-figure order needs to trust that the supplier is legitimate, ships on time, and stocks what the listing says. One unreliable supplier can cost you a buyer for good.
So the onboarding flow needs a real approval gate, not just a signup form. With Garnet, you build custom vendor application fields, review each applicant, and approve before they can list. That review step is your first quality filter, and in wholesale it's non-negotiable.
Catalog entry is the other half. Suppliers should connect a catalog, not retype it. Garnet syncs products, stock, and prices from a vendor's existing Shopify, WooCommerce, or PrestaShop store, and suppliers without one upload through a portal or CSV. The Vocal Market, a Netherlands-based marketplace where more than 100 vocalists sell acapella vocals to producers, runs exactly this way after outgrowing a previous multi-vendor app that couldn't flex to its B2B needs. Large audio files move through a storage integration, and the operator validates listings in one click.
Set minimum order quantities at this stage too. In wholesale, a case or a pallet is the unit, not a single item, and Shopify's B2B quantity rules let each supplier enforce a floor.
Step 3: Set wholesale and customer-specific pricing
This is the first mechanic a consumer marketplace never needs. B2B pricing isn't one public number. A given buyer might see a rate negotiated for their account, and the price often drops as the order quantity climbs.
The work splits in two. Suppliers set their base wholesale prices inside their vendor catalog, which flows in through Garnet. On top of that, Shopify's B2B price lists and catalogs let you show a specific company its own pricing, with tiered and quantity-based rules attached. On Shopify Plus those catalogs are unlimited; on Basic, Grow, and Advanced plans you get a capped version, up to three catalogs.
Be realistic about the limits here. Truly per-buyer negotiated pricing across many independent suppliers is where a multi-vendor B2B build gets genuinely hard, and some operators handle the most bespoke deals through quotes rather than standing price lists. Start with tiered pricing and a couple of buyer segments before you promise every account its own catalog.
Step 4: Turn on net terms, purchase orders, and tax exemption
Business buyers rarely pay by card at checkout. They send a purchase order, receive an invoice, and pay on Net 30 or Net 60. Offering those terms is often what wins the account, and it's why that McKinsey figure on six-figure self-serve orders matters: buyers will spend big online, but only when the payment mechanics match how their finance team works.
Shopify's B2B features cover this natively. You can set payment terms of Net 15, 30, 60, or 90, collect a deposit up front with the balance due later, and mark eligible company accounts as tax-exempt so they aren't charged sales tax at checkout. Company accounts group several buyers from the same business under one profile, each with their own login.
One caveat worth naming: extending net terms means you're carrying credit risk on the buyer side while still paying suppliers out on schedule. Decide your payout timing against your terms deliberately. Garnet lets you trigger payouts relative to fulfillment (say, 14 days after delivery) rather than at the moment of sale, which keeps your cash flow sane when buyers pay late.
Step 5: Handle quote requests, and where you'll need an app
Quotes are the one B2B mechanic that Shopify doesn't do natively, so plan for it honestly. Many wholesale deals start as a request for quote: the buyer specifies quantities and asks for a price before committing. There's no built-in RFQ portal on Shopify or in most multi-vendor apps.
Two workable paths exist. You can handle quotes manually through Shopify draft orders, where you build the order, apply custom pricing, and send it as an invoice, which works fine at low volume. Or you can add a dedicated request-a-quote app from the Shopify App Store when quote traffic grows enough to justify the workflow. Either way, treat RFQ as a bolt-on you add deliberately, not a feature you'll find bundled.
Step 6: Split orders, take commission, and pay suppliers
The last layer is the marketplace engine itself, and it's shared with every multi-vendor build, B2B or not. A buyer's order splits by supplier automatically, each supplier sees only their own line items, tax is allocated per line, and each gets paid out after you take your commission.
Garnet, a multi-vendor marketplace app for Shopify, handles the split, the per-vendor and per-product commission rates, and automated payouts through Stripe, Mollie, PayPal, or Airwallex. Because this piece is identical across marketplace types, the build a multi-vendor marketplace guide walks through it step by step, and the explainer on how marketplace split payments work covers the buyer-to-supplier money flow. No need to reinvent it here.
What it costs and how long it takes to build a B2B marketplace
Cost tracks the route you pick, not the number of suppliers. Here's the honest comparison across the three ways to create a B2B marketplace.
| Route | What you get | Typical cost | Time to launch |
|---|---|---|---|
| Custom build (agency or dev team) | Everything coded to spec, including RFQ and ERP hooks | $75,000 to $250,000+ | 6 to 12 months |
| Standalone B2B platform (Uppler, Virto) | A configured B2B marketplace on a separate site | Several thousand/mo plus setup | 2 to 4 months |
| Shopify + multi-vendor app + B2B tools | Marketplace layer plus native Shopify B2B features | App from $19/mo plus your Shopify plan | Days to weeks |
The catch on the cheapest route is the plan tier. The multi-vendor app is inexpensive, but the full native B2B suite (unlimited price lists, net terms at scale) lives on Shopify Plus, which starts around $2,300 per month. Standard Shopify plans include a lighter B2B feature set with the three-catalog cap, which is plenty for a first launch. For a full route-by-route breakdown, see the cost of building a marketplace.
Where B2B marketplace builds go wrong
The traps here are specific to wholesale, not to ecommerce in general.
- Treating pricing as an afterthought. Per-company and tiered pricing is the hardest part of a multi-vendor B2B build. Scope it before you promise buyers custom catalogs you can't deliver.
- Assuming quotes are built in. RFQ needs a separate app or a manual draft-order process. Decide which before a buyer asks for a quote you can't produce.
- Extending net terms without payout discipline. Paying suppliers before buyers pay you is a fast way to run out of cash. Align payout triggers with your terms.
- Onboarding suppliers you haven't vetted. One unreliable supplier on a five-figure order can lose you a buyer permanently. Approve by hand, especially early.
- Opening with empty shelves. Wholesale buyers won't return to a marketplace with nothing to order. Recruit real suppliers with real catalogs before you invite a single buyer.
The fastest way to build a B2B marketplace on Shopify
If you already run a Shopify store, or you're willing to start one, most of the two layers come pre-built. Shopify supplies the B2B buyer side (company accounts, price lists, net terms, minimum orders, tax exemption), and a multi-vendor app supplies the supplier side. You configure the marketplace instead of coding it, and most operators are live in days rather than months.
That's the trade in one line. A custom build hands you a codebase you own and a bill you maintain forever; the app route rents proven infrastructure so your time goes into recruiting suppliers and buyers instead of into plumbing. To weigh the operator features against the effort, the B2B marketplace software page details what running one on the Shopify marketplace stack actually involves. When you're ready to start a B2B marketplace, that's the shortest path from idea to first order.
FAQ
How do you build a B2B marketplace?
Add a multi-vendor layer to an online store for supplier onboarding, order splitting, and payouts, then layer B2B trading rules on top: wholesale price lists, minimum order quantities, net terms, and quote requests. On Shopify, a multi-vendor app handles the supplier side and Shopify's own B2B tools handle the buyer side, so you configure most of it instead of coding it.
How much does it cost to build a B2B marketplace?
A custom-coded B2B marketplace runs $75,000 to $250,000-plus over six to twelve months. A standalone B2B platform costs a few thousand a month plus setup. The cheapest route is a multi-vendor app on Shopify, from $19 per month plus your Shopify plan, though the full native B2B feature set (unlimited price lists, net terms at scale) needs Shopify Plus at roughly $2,300 per month.
Can you build a B2B marketplace on Shopify?
Yes. Shopify has no native multi-seller feature, but a multi-vendor app adds supplier accounts, order splitting, per-vendor commissions, and automated payouts, while Shopify's own B2B tools add company accounts, price lists, minimum orders, and net terms. Together they cover most wholesale marketplace needs. Quote requests (RFQ) still need a separate app.
Does Shopify support wholesale pricing and net terms for B2B?
Yes, through Shopify's B2B features: per-company price lists, tiered and quantity-based pricing, minimum order quantities, and Net 15/30/60 payment terms at checkout. The full suite is unlimited on Shopify Plus; standard plans include a capped version of up to three catalogs. Tax-exempt purchasing is supported per company.
How do you start a B2B marketplace with no suppliers yet?
Recruit and vet a handful of suppliers by hand before you open. In B2B, quality of supply beats quantity: a few verified suppliers with real catalogs and honest lead times outperform fifty unvetted ones. Onboard them personally, then bring buyers to a marketplace that already has stock worth ordering.
Is there a no-code B2B marketplace builder?
There is no single no-code B2B marketplace builder that does everything. The closest is a Shopify store plus a multi-vendor app configured through a dashboard, which covers supplier onboarding, order splits, and payouts without code, combined with Shopify's built-in B2B settings for pricing and net terms. Quote workflows usually need an extra app.
