Overview
PFinance is a multi-tenant business and personal finance management platform designed to track real-world cash flows across multiple independent revenue streams (e-commerce platforms, SaaS subscriptions, freelance client billing, and shared physical wallets). It replaces complex, error-prone spreadsheets with an authoritative double-entry-style ledger.
