Could you build this?
Partial The invoice-style interest calculator, forms, and diagnostic UI are straightforward to vibe-code, but statutory late-payment rules vary by jurisdiction and change over time, and the 'legal risk diagnostic' needs legal expertise to be accurate.
What it would actually take: Build a web app with a rules engine keyed by jurisdiction, with each statutory interest formula and demand-notice requirement encoded as versioned, testable data. The hard parts are verifying the rules against current statute and getting legal review of the diagnostic logic. That requires a practising lawyer or paralegal in each target jurisdiction, plus ongoing maintenance as laws change.
