VegaCity Nha Trang

High-volume automated eInvoice generation from parking transactions

Client: VegaCity Nha Trang | Industry: Commercial Real Estate & Parking Management

Project overview

Automated eInvoice generation
Real-time
Transaction-to-invoice flow

VegaCity Nha Trang, a premier commercial complex, partnered with AllSync to automate electronic invoice generation for thousands of daily parking transactions. The integration connects their parking management system directly to FAST eInvoice, ensuring every transaction is automatically converted into a compliant electronic invoice in real-time.

The high-volume challenge

Managing thousands of parking transactions daily presents a unique challenge for electronic invoicing compliance. Each parking session—whether 30 minutes or 8 hours—requires a proper tax invoice under Vietnamese regulations. Manual processing is impossible at this scale, and any delay in invoice generation creates compliance risks and operational bottlenecks.
