Engineered for High-Velocity Workshops

Eliminating manual parts typing and billing leakages across independent automotive service centers.

Multimodal Paper Ingestion

Mechanics capture photos of supplier invoices using mobile devices. The vision pipeline handles crumpled carbon copies, low-contrast dot matrix printouts, and stained margins without custom OCR templates.

OEM SKU Fuzzy Matching

Raw part descriptions are mapped to official Honda, Yamaha, and Toyota catalog numbers. The engine resolves spelling errors, vendor slang, and superseded part numbers before updating stock records.

Line-Item Math Verification

Every extracted line item is checked against unit costs, quantities, wholesale discounts, and tax totals. Discrepancies are flagged before purchase orders post to the accounting ledger.

Predictable Deployment Tiers

Transparent monthly subscription plans with local offline SQLite synchronization.
