THE PROBLEM

B2B e‑commerce faces significant friction today

It is very cumbersome for buyers and suppliers alike to discover one another and build new trade relations.

Credit Risk Burden

Credit Risk Burden

Buyers prefer deferred terms to ease cash flow, shifting large-invoice credit risk to suppliers.

Complex Onboarding

Complex Onboarding

To stay safe, suppliers impose a time-consuming and demanding onboarding process, discouraging potential partnerships before they even start.

Tedious Synchronization

Tedious Synchronization

After onboarding, the buyer experience remains tedious: account and order data must constantly be synchronized with their procurement suite, either manually or with a costly one-off integration.

The result? What should be simple business discovery becomes an expensive, time-consuming barrier that limits growth potential for both buyers and suppliers.

OUR SOLUTION

One account, many shops

b4b removes technical and commercial barriers between B2B buyers and suppliers so they can find each other, build trusted partnerships, and seamlessly exchange value in a digital world.

We issue trusted digital identities to B2B buyers so they can access all B2B online shops that recognize b4b as an Identity Provider — with one click, much like social logins in B2C. On first sign‑in to a participating shop, we share relevant account details for instant account creation.

Instant Credit Lines
Transaction

Instant Credit Lines

On first sign‑in, we issue a supplier‑specific instant credit line to the B2B buyer. This enables immediate shipping orders with zero risk for suppliers thanks to exclusive insurance arrangements.
