B2B Procurement Marketplace Software

Aggregate many suppliers into one branded catalog your business buyers order from. Garnet is the multi-vendor layer that turns a Shopify store into a B2B procurement marketplace, with supplier onboarding, order splitting, commissions, and automated payouts.

What is a B2B procurement marketplace?

A B2B procurement marketplace is one storefront where approved suppliers list catalogs and business buyers order from many of them at once, while the operator sets terms and takes a commission. Garnet Marketplace, a Shopify multi-vendor marketplace app, builds the sell side of one on your existing Shopify store, no custom code.

Sell side or buy side? Read this first

The phrase "procurement marketplace" gets used for two very different things, and mixing them wastes a demo call.

  • Buy side. A single company runs an internal catalog of approved suppliers, with purchase-order approvals, punchout into an ERP, and spend controls. That is classic e-procurement software.
  • Sell side. An operator runs a public or invite-only marketplace where many suppliers list and sell to business buyers, and the operator earns a commission on every order. That is a B2B trade marketplace.

Garnet is built for the sell side. If you want to be the marketplace, aggregate suppliers, and take a cut of trade flowing through it, you are in the right place. If you need punchout, requisition approvals, and spend analytics for your own buying team, a dedicated e-procurement suite fits better.

The pull toward sell-side marketplaces is not hype. The US B2B ecommerce market is worth an estimated $10.1 trillion in 2025 (Capital One Shopping research), and Amazon Business runs a third-party $35 billion-plus marketplace of business suppliers (Modern Retail). Procurement is consolidating onto marketplaces, and Shopify stores can own a slice of it.

Built for multi-vendor B2B


A supplier catalog under one roof

A procurement marketplace lives or dies on catalog breadth. With Garnet, each supplier gets their own vendor account, dashboard, and product catalog, and can be listing in about 6 minutes.

Invite known suppliers, open an application form, or bulk-import a roster of vendors instead of onboarding each one by hand. Suppliers already on Shopify, WooCommerce, or PrestaShop can sync their stock rather than re-key it.


One order, split across suppliers

Business buyers rarely need one supplier. Garnet lets a buyer add products from several suppliers to one cart and one Shopify checkout, then splits the order per vendor automatically, with tax allocated per line item.

Each supplier sees only their part to fulfill and ship, while you keep full admin visibility over the whole order lifecycle.


Commissions and automated payouts

You set the commission you take on trade, percentage, flat per product, or a vendor subscription. Garnet then pays each supplier their share through Stripe, PayPal, Mollie, or Airwallex.

Trigger payouts on a schedule or relative to fulfillment, for example 14 days after delivery, so cash flow matches your refund and return policy. No spreadsheets, no manual transfers.


White-label, no-code, and ERP-ready

Garnet is a no-code B2B marketplace builder. Configure commissions, supplier fields, and payout rules from a dashboard, and apply your own white-label branding across the storefront and vendor portal.

Suppliers connect through Shopify-to-Shopify, WooCommerce, PrestaShop, an API, or Google Sheets. Need a specific ERP feed? See the integration options, or we can build a custom one.

How to launch a B2B procurement marketplace on Shopify

Four steps take you from a single-seller Shopify store to a working multi-vendor B2B marketplace.

  1. 1

    Install Garnet

    Add Garnet from the App Store. Your checkout, theme, domain, and any Shopify B2B settings stay exactly as they are.

  2. 2

    Set commission and terms

    Choose your commission model, supplier application fields, and when payouts trigger. This is your business model, done in the dashboard.

  3. 3

    Onboard suppliers

    Invite suppliers, open an application form, or import an existing roster. Each lists their own catalog and syncs stock from their store.

  4. 4

    Approve and launch

    Review the first catalogs, publish, and open to buyers. Garnet splits every order and pays each supplier from the first sale.

A real multi-vendor B2B example: The Vocal Market

Honesty matters on a vertical page, so here is the real fit. Garnet does not claim an industrial-procurement giant as a customer. It does run The Vocal Market, a Netherlands-based B2B and B2C marketplace where 100+ vocalists supply high-quality acapella vocals to producers and studios who buy them.

It is the same sell-side job a procurement marketplace does: many suppliers, one branded catalog, per-supplier dashboards, one-click listing approval, and automated payouts. The founder moved to Garnet after a previous multi-vendor app would not build the vendor catalog and validation flow he needed. That review-and-approve step is exactly what keeps a supplier catalog trustworthy.

The model scales well beyond digital goods: industrial parts, spare components, professional supplies, and local wholesale all fit the same pattern. For more, browse the top B2B marketplaces or the guide to what a B2B marketplace is.

What a procurement marketplace needs, and who handles it

A B2B procurement marketplace has three layers: the multi-vendor side, Shopify's own B2B buyer features, and deep e-procurement tooling. Garnet, the multi-vendor marketplace app for Shopify, owns the first. Here is where each requirement actually lives, gaps included.

Procurement requirementHandled byHow it works
Supplier onboarding and catalogsGarnetSuppliers register, get approved, and manage their own catalog and orders from a dedicated dashboard.
One cart across many suppliersGarnetOrders split per line item, so each supplier fulfills only their part, with tax allocated per item.
Commissions and supplier payoutsGarnetPercentage, flat, or subscription commissions, with automated payouts via Stripe, PayPal, Mollie, or Airwallex.
Net terms and company accountsShopify B2B (Plus)Net 15, 30, or 60 terms and multi-buyer company logins are configured on Shopify's native B2B checkout.
Wholesale and tiered pricingShopify B2B (Plus)Customer-specific catalogs set fixed or percentage wholesale prices and quantity rules per company.
RFQ, quotes, and price negotiationNot GarnetNo built-in request-for-quote flow. Use a Shopify quote app or a dedicated e-procurement tool.
Punchout and PO approval chainsNot GarnetNo cXML or OCI punchout into SAP Ariba, Coupa, or requisition approvals. That is e-procurement software territory.

Buyer-facing B2B features (company accounts, net terms, wholesale catalogs) come from Shopify's own B2B toolset on Shopify Plus. Garnet adds the multi-vendor layer on top. For the wider picture, compare marketplace software or the general B2B marketplace software page.

Where Garnet fits, and where it does not

Garnet is the right fit for the sell side of a B2B procurement marketplace: many suppliers under one branded store, one combined cart, commissions, split orders, and automated payouts to every supplier. Pair it with Shopify's native B2B features for net terms, company accounts, and wholesale pricing, and you have a working B2B trade marketplace.

It is not e-procurement software. Garnet has no RFQ or quote-negotiation workflow, no punchout into ERP or procurement suites, no purchase-order approval chains, and no escrow. If your buyers require punchout catalogs, requisition approvals, or formal spend controls, plan for a dedicated procurement tool alongside the marketplace.

Frequently Asked Questions

Got questions about B2B procurement marketplace software? We have answers.

Ask a Question
  • What is a B2B procurement marketplace?

    A B2B procurement marketplace is one storefront where approved suppliers list catalogs and business buyers order across many of them at once, while the operator sets terms and takes a commission.

    Garnet builds the sell side of one on Shopify: supplier onboarding, order splitting, commissions, and automated payouts, with no custom code.

  • Can you build a B2B procurement marketplace on Shopify?

    Yes. Shopify sells for one merchant out of the box. Add Garnet and it becomes a multi-vendor marketplace where many suppliers list and sell through one storefront.

    Business buyers order across suppliers in a single checkout, orders split per vendor, and each supplier is paid automatically minus your commission.

  • Does Garnet support RFQ, quotes, or punchout catalogs?

    No, and it is worth being clear about it. Garnet has no request-for-quote workflow, and no cXML or OCI punchout into procurement suites like SAP Ariba or Coupa. It runs a catalog-and-cart B2B marketplace.

    If your buyers need punchout or formal RFQ approval chains, plan for a dedicated e-procurement tool on top.

  • How do business buyers place an order on a B2B marketplace?

    Buyers browse the combined catalog, add products from several suppliers to one cart, and check out through Shopify. Garnet splits that order by supplier behind the scenes.

    Each vendor sees only their own line items to fulfill, while you keep full admin visibility over the whole order.

  • How does a B2B procurement marketplace handle net terms and wholesale pricing?

    Net payment terms, company accounts, and customer-specific wholesale catalogs come from Shopify's native B2B features on Shopify Plus, not from Garnet.

    Garnet runs on top of that layer and adds supplier onboarding, order splitting, commissions, and automated payouts for the multi-vendor side.

  • How are suppliers paid on a B2B trade marketplace?

    Garnet deducts your commission on each sale and pays every supplier their share through Stripe, PayPal, Mollie, or Airwallex. Payouts can run on a schedule or relative to fulfillment, for example 14 days after delivery.

    That lets you align them with your refund policy. Garnet does not hold funds in escrow.
