Invoi is a modern e-invoicing platform for Vietnamese founders and accountants. It helps you send VAT invoices (Hóa đơn GTGT) and get paid faster — in one shared workspace.
#Who is Invoi for?
- Business owners / founders who need to issue compliant e-invoices quickly and see which invoices are matched to bank payments
- Accountants who want complete records without chasing files over Zalo
- Small teams that collaborate on customers, quotations, and invoices together
Invoi is designed for limited liability companies (công ty TNHH) and joint stock companies (công ty cổ phần) that are eligible to issue VAT invoices (Hóa đơn GTGT) with Tax Authority codes.
Business households (hộ kinh doanh) are typically required to use sales invoices (Hóa đơn bán hàng). Invoi does not support those yet.
#What makes Invoi different
#Built for Vietnam
VAT e-invoices with official Tax Authority codes and DK01 registration, aligned with Decree 254/2026/ND-CP — the current e-invoice framework under the Law on Tax Administration 108/2025/QH15 (replacing Decree 70/2025/ND-CP). Guidance follows Circular 91/2026/TT-BTC.
#Free eSignature
Every plan includes a free cloud eSignature (chữ ký số) from a licensed certificate authority. Sign and issue invoices in the browser — no USB token. Certificates are used in compliance with Decree 23/2025/ND-CP on electronic signatures and trust services (the current law succeeding Decree 130/2018/ND-CP).
#Sales and purchases in one place
Invoi pulls every invoice issued to your company from the tax portal — every supplier bill against your MST — and keeps it next to the invoices you issue. AR and AP live in one workspace: sales you send, purchases you receive.
#Bank statements that reconcile
Import bank statements and match each transaction to an invoice. Matched vs unmatched stays accurate, and month-end reconciliation is faster for you and your accountant.
#Owner + accountant together
One workspace. Two perspectives. Owners stay on cash flow; accountants stay on the books — same source of truth.
#From invoice to capital
Issue invoices, prove your cash flow, then unlock Invoi Capital (VIP) — a revolving line of credit backed by cash flow and verified by invoices, through partner banks.
