# Invoices Used Outside UNOSOF

{% hint style="success" %}
Home/ Accounting/ SRI Electronic Transfer/ **SRI Electronic Management.**
{% endhint %}

The option ADD BLANK INVOICE button, it is used to skip a sequential (SRI Invoice ID) and use it in another (accounting) system where it is necessary to use the numbering (sequential) for both export and national.

#### Example

You want to skip the sequential 3005 of the batch of national invoices, for the sale of a Vehicle&#x20;

**Step 1:** Press the Add Blank Invoice button (appears only in the SRI/Invoice/Generate/Sign/Send module)

**Step 2:** Check in the module: **Invoices Used Outside UNOSOF.** You will see the 3005 sequential is skipped.

Step 3: An informative note can be added in the NOTE field

## Return a Sequential to use it in UNOSOF

By mistake, the sequence could have been skipped, with Add Blank Invoice.&#x20;

We will use the same previous example: return the sequential of the National lot 3005 to the SRI Invoice ID&#x73;**.**

{% hint style="info" %}
This option works when the skipped sequence is the last one AND the following sequences have not been used yet.
{% endhint %}

**Step 1:** The skipped sequence (3005) is no longer available, and can be verified in the ADD BLANK INVOICE segment (national)

**Step 2:** Find the sequential (3005) in Invoices Used Outside UNOSOF

<figure><img src="/files/oPyafxpHcW00SDZgbOde" alt=""><figcaption></figcaption></figure>

**Step 3:** Press the DELETE button to delete that skipped sequence, and return it to the SRI-XML generation module

<figure><img src="/files/nMHj0fyUjG8cTZBU12zg" alt=""><figcaption></figcaption></figure>

**Step 4:** Check if the sequence is available again, in the SRI-XML generation module, Add Blank Invoice (national) segment

<figure><img src="/files/6RFPGOwx9eizYkv0m3Q1" alt=""><figcaption></figcaption></figure>

## Return a sequencial to use it (when it is not the last sequence )

You should follow the same steps of the previous option, but the sequential will be available in the option: **Unused (Skipped) Invoices**, since it is not the last one, for example the sequential 2989 instead of the last one 3005.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://manual.unosofbooks.com/accounting/sri-electronic-transfer/sri-electronic-management/invoices-used-outside-unosof.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
