How Do We Show Each Trade Buyer the Prices Their Supplier Agreed With Them on Our Marketplace?

B2B marketplaces cannot show negotiated supplier prices to key buyers, so deals happen off-platform. We build buyer-specific price lists that apply at checkout.

Quick answer — TL;DR

Negotiated pricing breaks marketplaces built for one public price per listing: a large buyer has agreed contract prices with a supplier, sees the list price on your site, and orders by email instead. We build buyer-specific price lists that suppliers manage, that apply automatically when the buyer logs in, carry validity dates and quantity breaks, and are checked on every order line.

Our price is not the one on your website

A regional housing maintenance contractor buys heavily from one of your suppliers. They agreed a price list last year: lower prices on the fifty items they buy most, quantity breaks on a few more, valid until the end of March. When their buyers log into your marketplace, they see the public prices. So they email the supplier's rep with their order, the rep keys it into the supplier's own system, and your marketplace sees none of it.

The supplier would happily sell through the marketplace, if it could show the agreed prices. Your platform shows one price per listing.

Why one price per listing is not enough in B2B

Trade pricing is personal. Large and regular buyers negotiate. Suppliers run price tiers for different customer groups, quantity breaks, contract prices for named customers and time-limited deals. A consumer marketplace model, with one visible price per product, cannot represent any of this.

Suppliers also hold their price agreements in their own systems or spreadsheets, and changes during the year, such as a price review or an extended contract, need to reach the marketplace too.

What missing contract pricing costs

Your biggest buyers, who could bring the most volume, are the ones most likely to order around the marketplace. Suppliers see the marketplace as a channel for small, one-off buyers rather than their core accounts. When contract prices are applied by hand after the order, mistakes creep in and buyers query invoices.

Contract prices that expire without anyone noticing cause the opposite problem: a buyer charged the old contract price months after the supplier reviewed it, and a difficult conversation about who absorbs the difference.

The buyer pricing we build

  1. Price list structure: prices can be set per supplier for a buyer group, a named buyer account or a named site, with products, quantity breaks, start and end dates.
  2. Supplier maintenance: suppliers upload or update price lists through a portal or file import, or by feed from their own system where it supports it, with changes previewed before they go live.
  3. Checkout application: when a buyer logs in, the prices they see and pay are resolved from the most specific applicable list, falling back to the public price where no agreement exists.
  4. Line checks: each order line records which price list applied, so invoices and disputes can be checked against the agreement.
  5. Expiry alerts: suppliers and your account team are told before contract prices expire, so reviews happen before the buyer gets a surprise.
  6. Confidentiality: buyers only ever see their own prices, and suppliers only see price lists they created.

Many marketplace platforms support customer-specific pricing to some degree. We use what your platform offers and add what is missing, rather than rebuilding it.

When key buyers can order on the platform

The contractor's buyers log in and see their agreed prices, with quantity breaks shown on the product page. Orders flow through the marketplace, with the consolidated invoicing and credit terms that come with it. The supplier's rep spends time with the buyer rather than keying orders. Your team can finally see how much trade your biggest relationships represent.

Price reviews become an event with a date, visible to both sides, rather than an email chain that may or may not reach the marketplace.

Do your key buyers order around you?

  • Large buyers email suppliers directly because their prices are not on the site.
  • Your platform supports only one price per listing.
  • Contract prices are applied by hand after ordering.
  • Expired contract prices have caused invoice disputes.
  • Suppliers see the marketplace as only for small buyers.

FAQ

Frequently asked questions

The questions readers ask us after this guide.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Can buyers see other buyers' prices?

No. Each buyer sees only their own resolved prices. This is enforced on the server, not just hidden on screen.

How do suppliers keep price lists up to date?

Through a file upload, a simple portal or a feed from their own system. Changes are previewed and dated before they apply.

Does this work with our platform?

If your platform supports customer-specific pricing, we build on it. If not, we add a pricing service that the checkout calls.

What about quotes that turn into prices?

An accepted quote can create a buyer-specific price for that order or a period, depending on how the supplier wants to treat it.
