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<sup>st</sup> July. The company can back-date to as early as 6<sup>th</sup> June. If the company chooses 15<sup>th</sup> June, it can only issue that invoice if no invoice has been issued with a date after 15<sup>th</sup> June.

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

### 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.

![](/files/GB60TTU4Zg6Yaq4hzc2x)

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).
