Trade credit in B2B portals: ERP integrations and limits

Mikołaj Lehman

CEO & Founder

Trade credit in B2B ecommerce is purchasing on invoice within limits, approved by ERP or an external finance partner.

Where limits live

ERP is usually source of truth; portals cache with short TTLs and invalidate on ERP events.

Multi-currency setups follow finance policy for conversion and rounding.

Holds and escalations

Breaching a limit should not silently wipe carts, show cause and a sales contact path.

Audit log: who changed limits and why.

Testing and compliance

Regression packs for collections, partial returns and invoice corrections.

GDPR docs for financial data shown in the portal.
