Challenges you're facing
After every payment, staff must open a separate e-invoice application, re-enter customer details — 5–10 minutes per invoice
The system listens for payment.completed and auto-issues a fully populated invoice from order data — no manual action required
Incorrect invoice series used, or quota exceeded beyond what's registered with the Tax Authority — regulatory violation risk
Manage each registered series, receive alerts before quota is exhausted, and prevent use of any unregistered series
Customers request invoices but staff can't locate them — files scattered across emails and personal computers
All invoices stored centrally, searchable by invoice number, customer name, or tax period — download PDF/XML instantly from within the system
End-of-quarter tax report compilation from multiple Excel files is error-prone and takes hours
The reporting module automatically aggregates by tax period and exports in the exact format required — ready in seconds
Key features
Built for modern businesses — no complex setup, ready to use immediately.
Provider Configuration
Select & Configure Provider
Supports MISA meInvoice, VNPT-Invoice, Viettel sinvoice, and FPT eInvoice. Enter credentials once — the system stores them securely encrypted.
Two Configuration Contexts
Configure independently for sales invoices (issued to customers) and operator invoices (received from partners or suppliers).
Invoice Series Management
Register and manage series approved by the Tax Authority. Receive automatic alerts when a series quota is running low.
Create & Issue Invoices
Auto-Issue on payment.completed
When a customer pays successfully, the system automatically creates and issues a VAT invoice — no staff intervention needed.
Manual Invoice Creation
Enter individual line items, select VAT rates of 0%, 5%, 8%, or 10% — the system calculates totals and formats everything to the tax standard.
Email to Customer
Send PDF and XML invoices directly from the system. Customers receive a copy with a valid Tax Authority confirmation code.
Invoice List & Details
Full Status Tracking
Status pipeline: Draft → Pending → Issued → Adjusted → Cancelled → Error. Fast search and filtering by any criteria.
Tax Authority Confirmation Code
The Tax Authority confirmation code (mã CQT) is displayed directly in the invoice detail view. Download tax-compliant PDF/XML at any time.
Adjustments & Cancellations
Adjust an Issued Invoice
Create a new adjustment invoice per regulatory requirements — the original confirmed invoice is never edited directly.
Cancel an Invoice Properly
Draft a cancellation memo, send notice to the Tax Authority via your provider. The original invoice remains; only a 'Cancelled' status is added.
Tax Reporting
Periodic Tax Reports
Aggregate revenue and output VAT by month or quarter. Export files in the exact format required by the Tax Authority.
10-Year Archiving
All invoices retained per Decree 123/2020/NĐ-CP requirements. Retrieve any invoice from the past 10 years at any time.
