B2B Marketplace Development
We build multi-vendor B2B marketplaces with enterprise purchase flows: request for quotation (RFQ), bulk ordering, approval workflows, automated invoicing and logistics integration. Platforms that connect suppliers and buyers at scale.
A B2B marketplace is not an online store with more users: it's a complex business ecosystem
B2B marketplaces connect businesses with businesses. Purchase flows are radically different from B2C: there are internal approval processes, price negotiations, orders of thousands of units, framework agreements, invoicing with 30-60-90 day payment terms, and sector-specific logistics requirements. Building a successful B2B marketplace requires understanding both the technology and the dynamics of inter-business commercial relationships.
The multi-vendor architecture of a B2B marketplace must manage dozens or hundreds of sellers, each with their own catalog, prices, stock, shipping conditions and return policies. Unlike conventional e-commerce, B2B buyers don't add a product to the cart and pay by card: they send requests for quotation (RFQ), negotiate terms, require approval from their purchasing department, and generate formal purchase orders that integrate with their ERP.
Vertical B2B marketplaces (specialized in a sector) are transforming entire industries. Instead of relying on PDF catalogs, trade shows and phone calls, professional buyers can search, compare and purchase products from multiple suppliers on a single platform. The operational efficiency this generates is enormous: procurement times reduced from weeks to hours, price and terms transparency, and complete traceability of every transaction.
At Soamee we have built B2B marketplaces in production. Brytspace is a marketplace platform for the B2B events sector connecting organizers with service, equipment and venue providers. Somos Musica operates as a music licensing marketplace where record labels and content creators negotiate licenses and royalties. Each with its own business particularities, but sharing the same technical pillars of a well-designed B2B marketplace.

What we build in every B2B marketplace
The technical pillars a B2B marketplace needs to connect suppliers and buyers efficiently.
Multi-vendor architecture
Platform managing multiple sellers, each with their own admin panel, product catalog, pricing, stock, shipping conditions and return policies. Guided onboarding for new sellers with business verification (KYB), tax documentation and payment method configuration. Centralized dashboard for the marketplace operator with per-seller performance metrics, commission management and content moderation.
RFQ and negotiation flows
Complete Request for Quotation system allowing buyers to send quote requests to one or multiple suppliers simultaneously. Sellers respond with custom offers including price, delivery time, payment terms and validity. Buyers can compare offers in a table, negotiate conditions and accept the most favorable. Complete negotiation history and automatic conversion of accepted offers to purchase orders.
Bulk ordering and framework agreements
Support for large volume orders with tiered pricing by quantity, negotiated volume discounts and minimum order per supplier. Framework agreements fixing conditions (price, lead time, quality) for a set period, with partial orders deducted from the total agreed volume. Recurring purchase lists for regularly ordered products and one-click reordering.
Approval workflows
Multi-level approval system reflecting the buyer organization structure. Employees create purchase requests that pass through approvers based on amount, category or department. Flexible approval rule configuration per buying company: automatic approval below a certain amount, simple approval by direct manager or sequential approval through multiple levels. Notifications and reminders to prevent process blocks.
B2B invoicing and payments
Invoicing system adapted to B2B practices: per-order or consolidated monthly invoicing, 30-60-90 day payment terms, SEPA direct debit, bank transfer with reconciliation reference and payment against invoice. Integration with Stripe Connect or Mangopay for split payment management between marketplace and sellers. Automatic invoice generation with full tax data, accounting system integration and overdue management with automated reminders.
Logistics integration
Connection with seller and carrier logistics systems for B2B order fulfillment management. Support for multiple modalities: direct seller shipping, centralized marketplace fulfillment, dropshipping and warehouse pickup. Unified tracking aggregating information from multiple carriers in a single buyer view. Returns and claims management with flows adapted to each seller.
