Invoi.vn
Bootstrapped Vietnamese e-invoicing app built for SMEs facing mandatory tax-authority compliance
Invoi.vn is a bootstrapped Vietnamese e-invoicing SaaS, in beta since March 2026, that helps SMEs comply with Vietnam's mandatory e-invoicing requirement through a flat monthly subscription starting at USD 8.50 with unlimited invoices and real-time tax-authority integration. It is best for Vietnamese SMEs and sole proprietors needing affordable, self-serve compliance without hiring an accountant. Caveat: it is an early-stage beta product still building its funding round and paying-user base, so long-term support and roadmap execution are unproven.
Judged on regional fit, not vendor glossies.
Built specifically for Vietnam's tax-authority e-invoicing mandate; not applicable to Thailand's e-Tax system.
Deep localization to Vietnam's specific e-invoicing regulation, but confined to a single SEA market and still in beta.
Not a messaging-based product; no LINE Official Account integration.
Not an e-commerce marketplace tool; focused on tax-compliant invoicing.
Flat USD 8.50/month for unlimited invoices is priced specifically for small and micro Vietnamese businesses.
- ✓Flat, low monthly price makes compliance affordable for micro and small businesses
- ✓Real-time tax authority integration reduces manual e-invoicing compliance work
- ✓Self-service onboarding without needing an accountant or IT integrator
- ✓Planned invoice financing could directly address late-payment cash-flow gaps for Vietnamese SMEs
- ×Early-stage beta product launched in March 2026, with an unproven long-term track record
- ×Vietnam-only, unlike established multi-product Vietnamese accounting suites
- ×Still raising its first funding round, which creates uncertainty about long-term viability
About Invoi.vn
Invoi.vn is a Vietnamese SaaS startup, founded by Phan Viet Hung and launched into beta in March 2026, that helps small and medium-sized enterprises comply with Vietnam's mandatory e-invoicing requirements. Vietnam has required e-invoicing since 2022 for its roughly 940,000 active SMEs, with non-compliance carrying fines exceeding USD 3,000, and Invoi.vn was built as an affordable, self-serve alternative to enterprise e-invoicing software for that market. The bootstrapped platform offers a flat monthly subscription with unlimited invoices, real-time integration with Vietnam's tax authority, and online onboarding without needing an accountant or IT integrator, and it plans to add invoice financing so businesses can convert unpaid invoices into working capital through banking partners.
Key Features
Best For
Southeast Asia Fit
Invoi.vn was built specifically around Vietnam's mandatory e-invoicing regime, which requires real-time submission to the tax authority and carries fines above USD 3,000 for non-compliance, a requirement that does not exist in this form in other SEA markets. Its flat, low-cost subscription and self-service onboarding target the roughly 940,000 Vietnamese SMEs and micro-businesses that enterprise e-invoicing software typically prices out, rather than adapting a regional or global invoicing tool to Vietnamese tax rules after the fact.
