Trading and service SMEs can run bookkeeping and e-invoicing from one online subscription without IT staff. Firms with branches in several provinces can let staff post vouchers from any location under controlled permissions, and household businesses can keep ledgers under Circular 88.

No installation, update, bug-fix or maintenance fees, with plans from VND 146,000 per month paid in 6-month, 1-year or 2-year terms. More than 300 reports with drill-down give managers detailed financial views without extra BI tools. Search across millions of vouchers returns in seconds, and free Fast e-Invoice integration removes a separate invoicing subscription.

Vietnamese SMEs are shifting from installed accounting software to cloud subscriptions as e-invoices, e-tax filing and new accounting circulars require frequent updates. The move of household businesses to self-declared tax and the upgrade roadmap for e-invoices and e-documents in 2026 add demand for online accounting bundled with compliant invoicing.

FAST's business registration was first issued on 18 June 1997 in Hanoi, and the company is approaching its 30th anniversary. It has won 12 Sao Khue awards, 2 BIT Cups and the Make in Vietnam award, and in 2025 VINASA named it in several Top 10 categories. Its Fast e-Invoice service is recognized by the tax authority.
