SabiLedger is an autonomous multimodal business ledger designed for emerging markets informal retail, where over 80% of merchants still track credit on messy paper notebooks and lose up to 18% of their annual turnover to uncollected debts.
Powered by Meta Llama 3.2, SabiLedger turns photos of handwritten merchant debt books and colloquial voice notes into verified financial records. We strictly decouple perception (Llama 3.2 90B Vision & Voice) from financial arithmetic (Deterministic Accounting Core) to guarantee 100.0% zero math hallucination. Merchants can review extracted debts with confidence badges, log colloquial voice payments, and send polite one-tap WhatsApp payment reminders with verified customer balances via wa.me deep-links.
