Partial The reminder UI and email drafting are easy to vibe-code, but the late-fee calculations across UK, EU and contract rules need legal accuracy that AI alone cannot guarantee.
What it would actually take: The UI, invoice entry and LLM-written emails and WhatsApp messages are straightforward. The hard part is encoding the statutory interest rules by jurisdiction (UK Late Payment Act, EU Directive variants, contract-rate edge cases) and keeping them current. That requires legal review and a maintained rules engine, not just code generation.
