How to Build a Wholesale Sourcing Marketplace

1. 1

   Step 1 · Scope

   Choose the buyer and supplier relationship

   Decide which businesses can sell, who may buy and what product categories are in scope. Determine whether the site supports discovery and inquiries, direct purchasing, or both. Start with a narrow catalog and state clearly whether listed prices are final, indicative or available only after supplier contact.

   Step 2 · Catalog

   Set useful supplier and product information

   Ask suppliers to provide product descriptions, minimum order details, lead times, pack sizes and the regions they serve. Have sellers confirm which information is current. If a buyer needs a formal quote, explain how to request it; the feature catalog does not list a dedicated RFQ or tender workflow.

   Step 3 · Terms

   Explain ordering and cross-border responsibilities

   Set expectations for deposits, samples, shipping, customs, taxes, returns and damaged goods. These terms vary by supplier and destination and are not handled automatically by a directory. Ask each seller to state which markets they serve and who arranges documentation before a buyer places a large order.

   Tradly: Tradly supports marketplace checkout and delivery options when configured; customs, trade documentation and supplier terms need your own operating process.

   Step 4 · Build

   Use AI to draft buyer and supplier journeys

   Give the AI builder a sample supplier catalog and a small retailer’s sourcing questions. Ask for supplier profiles, product pages, category browsing and an inquiry step. Review all claims about lead time, origin, certification, minimum order and shipping with the supplier before publication.

   Step 5 · AI

   Help buyers discover and compare suppliers

   Train an agent on sourcing policies, catalog terminology and supplier-submitted details so it can explain what information to request. AI search can help buyers query listing text in natural language. Do not let an agent promise capacity, certify suppliers or negotiate binding trade terms.

   Step 6 · Launch

   Pilot a small supplier catalog

   Invite suppliers who can keep their catalog details current. Ask a few buyers to search for products, compare suppliers and send an inquiry. Review whether they understand ordering terms and who handles shipping and documentation. Add more categories after the first buyer-supplier conversations are working smoothly.
