FinPro
A deterministic, offline financial workstation that converts structured time into reproducible, defensible money artifacts.

FinPro in plain English.
FinPro is a deterministic, offline-first financial workstation designed to close the gap between work performed and money correctly documented. Freelancers, contractors, and households routinely lose income not because they charge too little, but because time tracking, calculation, and billing systems fail silently—through missed hours, manual transcription, spreadsheet formula drift, and inconsistent rate application. FinPro ingests structured time data (from CalGen or manual entry), applies explicit rate rules, and produces reproducible financial outputs: earnings summaries, invoices, receipts, expense records, and net-pay estimates. Every line item shows its derivation. Totals are always calculated, never typed. Rate definitions are versioned, calculations are immutable after issuance, and regenerated artifacts always match their originals.
What you get.
- Deterministic earnings calculation from structured time, tasks, and projects (same input → same output)
- Explicit rule-based rate application (base, overtime, weekend, holiday, per-task, per-project)
- Versioned rate definitions with effective-date boundaries to prevent retroactive drift
- Integrated invoice and receipt generation directly from calculated data—no transcription step
- Immutable invoice line items preserving applied rates, quantities, and totals at issuance time
- Transparent gross-to-net estimation using user-defined deductions with labeled breakdowns
- Expense tracking with client/project attribution and direct invoice inclusion
- Spreadsheet-grade exports (CSV, JSON, XLS/XLSX) for verification and downstream use
- Fully offline operation with local data storage and no subscription dependency
Built for operators, not enterprises.
Freelancers and independent contractors who bill hourly or per-project, need invoice records that hold up under client or tax scrutiny, and refuse to pay a monthly subscription just to access their own financial data.
