Hi DevHunt 👋 I'm Prabin, a solo developer from Nepal who works on accounting and ERP systems. Every product that touches money eventually gets the same request: "Can we see a P&L? Cash flow? Who owes us what?" Building that properly takes months: statements that reconcile to the cent, drill-down from any figure to the ledger lines behind it, permissions enforced on the server. Numeralens is that module, finished, as Next.js + TypeScript source with a one-time licence (no per-user fees, no licence server). What developers usually ask about: - Your data: one typed DataAdapter (23 methods), or point it at a REST URL in Settings - The AI: a deterministic engine computes every figure; a model answer containing a figure it didn't supply is rejected, and everything works with no API key - Security: every API route is checked per role on the server; the tests try every route x role pair (174 checks) Demo, no signup (pick a role): https://demo.numeralens.com Founding price for the first 30 buyers: $149 Standard / $479 Extended. What would you need to see before putting this inside your product?
