  • Built-in PDF invoice generation and automated email dispatches
  • Turnkey sales rep commission assignment and basic reporting
  • Pre-configured customer registration and credit line approval dashboard
  • Managed cloud hosting for wholesale catalog uptime

Mondu

Mondu is not a software utility; it is a full-stack financial institution taking default risk and providing credit capital. Generating a frontend BNPL widget is easy, but acquiring regulatory licenses, debt financing facilities, and credit bureau integrations cannot be done with code generation.

  • Checkout payment method selection widget for Net Terms
  • Buyer portal for viewing invoice payment schedules and open balances
  • Automated email dunning notifications for unpaid invoices
  • Standard WooCommerce, Shopware, and Shopify checkout plugins
  • Admin dashboard displaying order statuses and payout summaries

what you lose

  • Non-recourse factoring where Mondu absorbs total default loss on unpaid invoices
  • Upfront cash advance paid to the merchant immediately upon order shipment
  • Instant sub-second corporate credit risk checks against EU rating agencies
  • Compliant debt collection infrastructure across multiple European jurisdictions
  • Institutional debt financing lines backing customer payment terms

real moats

  • Non-recourse balance sheet financing and bank credit facilities
  • European financial regulatory compliance and licensing framework
  • Integrations and historical scoring datasets with European credit bureaus
