Start with SparkLayer — highest vibe code, weakest moat.
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

- 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

SparkLayer
If you only need a quick-order matrix and customer-tagged wholesale discounts on Shopify, an AI coding agent can build a custom solution in weeks.
