BiG-M Lite is an AI-first accounting and tax assistant designed for freelancers and small businesses operating across different languages, currencies, jurisdictions, and tax systems.

Instead of building a separate accounting product for every country, BiG-M Lite uses one deterministic accounting engine. The user is profiled first, and that profile determines the active language, currency, jurisdiction, business context, and regulatory requirements without changing the core engine or rewriting application code.

Business data can enter through native transaction entry, uploaded documents, OCR-extracted receipts and invoices, or the AI assistant.

Meta Muse is used after profiling to discover and structure the regulatory information required for that user, including applicable tax rules, rates, thresholds, and supporting official sources.

Muse provides regulatory context, while BiG-M Lite's deterministic One Engine performs the actual accounting, ledger, reporting, profit, and tax calculations.

The demo shows the same application adapting to three different users:

Nikos — English, United States, USD
Maya — Bahasa Indonesia, Indonesia, IDR
Haruto — Japanese, Japan, JPY

Each user gets a localized workspace and jurisdiction-specific tax context while the underlying engine remains unchanged.

The core idea is simple:

Profile the user → use Muse to discover the required regulatory context → process business records through One Engine → produce localized accounting and provisional tax results.

Three users. Three languages. Three currencies. Three jurisdictions. One engine.
