Invoices
JoyOne’s invoice module lets you generate, send, and track electronic invoices — fully compliant with Vietnamese e-invoice regulations (Nghị định 123/2020/NĐ-CP).
How It Works
Invoices in JoyOne are powered by the E-Invoices plugin, which connects to a certified e-invoice provider. Once enabled, invoices can be issued directly from an order.
Prerequisites
Before issuing e-invoices, you must configure the E-Invoices plugin under Settings → Plugins → E-Invoices and connect your e-invoice provider credentials.
Required setup:
- Tax code (Mã số thuế) of your business
- E-invoice provider account (e.g. VNPT, MISA, Viettel)
- Invoice template (provided by your e-invoice provider)
- Digital signature certificate
Issuing an Invoice
Complete the order
An invoice can only be issued from an order in Completed or Confirmed status.
Open the order
Go to Orders, find the relevant order, and open it.
Click “Issue Invoice”
Click Issue Invoice in the order actions panel.
Fill invoice details
- Buyer name and tax code (if B2B)
- Invoice series and template (pre-filled from plugin config)
- Notes (optional)
Submit
Click Issue. The invoice is sent to your e-invoice provider, signed digitally, and returned with a unique invoice number.
Invoice Statuses
| Status | Description |
|---|---|
| Draft | Not yet submitted to provider |
| Issued | Submitted and signed by provider |
| Sent | Delivered to buyer by email |
| Cancelled | Voided (requires replacement invoice if applicable) |
Sending to Customers
After issuing, send the invoice to the customer:
- Email — attached as a PDF
- Download — share the PDF or XML file manually
Cancelling an Invoice
Cancelling an issued invoice creates a cancellation record. Depending on regulations, a replacement invoice may be required.
Go to the invoice → Cancel Invoice → provide a reason. Both the original and cancellation records are kept for audit purposes.
