KEEP — THE UI ISN'T THE MOAT
What you pay Mondu for is not the checkout iframe or Shopify plugin—those are basic software wrappers. You are paying for immediate capital payout while offloading 100% of buyer default risk on 30-to-90-day invoice terms. Mondu runs real-time credit checks across European credit bureaus, advances working capital, and manages debt collection under strict European financial regulations. Rebuilding the UI using Cursor takes a few days, but funding millions in invoice working capital and obtaining credit institution clearance cannot be coded.

Why this verdict
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.

The one-shot build prompt
Paste it into your agent of choice. Nothing else needed.
Build a custom B2B Net Terms payment plugin for a web checkout. 1. DATA MODEL: Create entities for Company Account (id, vat_number, credit_limit, current_balance, status), PaymentTerm (id, days_allowed, interest_late_pct), Invoice (id, company_id, order_id, total_amount, due_date, status: [pending, paid, overdue]), and RemindersLog. 2. CORE LOGIC: At checkout, display 'Invoice Net Terms' if Company Account status is ACTIVE and order_total + current_balance <= credit_limit. On order placement, create an Invoice record set to due_date = today + PaymentTerm.days_allowed, update current_balance, and place the order in Processing state. 3. AUTOMATION & DUNNING: Create a daily cron job that scans overdues. For invoices where due_date < today and status is pending, mark as overdue, set Company Account to SUSPENDED if overdue > 14 days, and send automated email reminders with PDF invoices attached. 4. FAILURE MODES: Handle credit limit race conditions using atomic database locks during checkout. Block checkout if pending overdue invoices exist. 5. OUT OF SCOPE: Third-party non-recourse debt financing, real-time credit rating score checks, legal collection automation.

FAQ
+Can I really replace Mondu with an AI-generated app?
NO — YOU CANNOT REBUILD A REGULATED FINTECH BANKING ENGINE WITH AI PROMPTS. 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. An MVP takes roughly 2 weeks; matching the product properly is closer to 12-24 months, due to debt financing lines, regulatory compliance, real-time credit underwriting, and collection infrastructure.
+How long does it take to rebuild Mondu?
A usable internal version: 2 weeks. A version you would sell or bet a business on: 12-24 months, due to debt financing lines, regulatory compliance, real-time credit underwriting, and collection infrastructure, mostly spent on synchronous integration with european credit rating agencies (creditreform, schufa, dun & bradstreet) in under 2 seconds during checkout.
+What do you actually lose by leaving Mondu?
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
+Is it legal to build a Mondu alternative?
