Connect the system, spreadsheet or table that already holds your products, prices, inventory or capacity. Use the any-system onboarding guide to prepare the right connection in your existing stack. Middleman’s supplier integration model keeps that system authoritative, with no duplicate catalogue to maintain by hand. Start with the integration quickstart and check release status.

What to map from your system

  • Manufacturer and manufacturer part number.
  • Your stock code or listing reference.
  • Quantity available and minimum order quantity.
  • New, used, refurbished, surplus, or another stated condition.
  • Location and available delivery or collection terms.
  • Price, currency, tax basis, quantity tiers, and validity period.
  • Photos, inspection records, certificates, or other supporting evidence.
Missing information stays unknown until someone confirms it. A category, price, or listing title does not determine condition.

How buyers see the information

Middleman keeps your listing reference alongside a separate product identity. Price and availability carry their source, date, quantity, market, and stated terms so a buyer can compare them fairly. A listing or stock response records what was reported at that time. A current quotation confirms the terms a buyer can rely on now.
Use one consistent manufacturer part number, but keep your own stock code or listing reference. Both help a buyer reconcile the item without confusing your reference with the product’s identity.

Before anything is shared or sent

Agree which source fields may be shared before activating a feed. The preview supports public-price context only; keep customer-specific discounts and confidential terms out of its sample payloads. Review the intended recipient, content, and purpose before any external action proceeds.
