9.5 Invoice Issuance

Some information which needs to note during input through 2 modules:

Invoice date: If the company needs to back-date an invoice, you must enter the desired date manually. For Viettel providers, the company can back-date up to 25 days from the current date, provided no invoice has been issued after the chosen date (to maintain sequential numbering).

For example, today is 1^st July. The company can back-date to as early as 6^th June. If the company chooses 15^th June, it can only issue that invoice if no invoice has been issued with a date after 15^th June.

Invoice number: Generated automatically according to the invoice form number (mẫu số) and series symbol.

a) Input data through Inventory Management Module

Open E-invoice issue screen >> vouchers which choose will be shown on data grid

b) Input and issues invoice through Account Receivable Module

Choose Release batches function

Choose Voucher which issue >> choose E-invoice checkbox and Click Execute

Create an invoice issuance notice

When to use: When you need to declare an issuance notice for each invoice form before use: serial, the range of numbers allowed for issuance, and tracking of used / deleted / lost / cancelled numbers per form.

To create an invoice issuance notice, proceed as follows:

1. The system auto-generates the Issue number and pre-fills the company details (name, address, tax code, phone); enter the Issue date.

2. On the grid, add each invoice form: enter/select the Form (press F3), Form name, Form serial, Serial.

3. Enter the number range: From no. / To no. and the tracking numbers (used, deleted, lost, cancelled) if any.

4. Click Save to finish. Use New to create another issuance notice, Delete to remove an unused one.

• Operational notes:

  • Form serial is 11–13 characters; Serial follows the VN/YY[E/T/P] format (6 or 8 characters).

  • Company details are taken automatically from Company information and cannot be edited here.

  • An issued notice cannot be edited or deleted (view only).
