## How to Configure GST E- Invoice Generation in Sale Bill ?
In this tutorial, we’ll explore the **Generate GST E-Invoice** setting in detail. You’ll learn how the three available modes — **None**, **Prompt**, and **Silently** — work, and how to choose the right one for your business workflow.
***
### Access Sale Voucher Configuration
* Navigate to **Sale Voucher Configuration**.
* Select the relevant **Billing Series**.
* Under the Other Settings - 2.
* Locate the option labeled as:
> **"Generate GST E-Invoice"**
### **Parameters Defining the Feature’s Behavior**
#### **None** – *Manual Generation Only*
* **Function:** The system will **not** generate a GST E-Invoice automatically.
* If needed, you must generate it **manually** from the invoice portal or through the E-Invoice utility.
***
#### **Prompt** – *User Confirmation Required*
* **Function:** After saving the bill, the system will ask if you’d like to generate the GST E-Invoice.
* **Example:**
* Save the transaction.
* A confirmation pop-up appears: *“Generate GST E-Invoice?”*
* Click **Generate** to proceed.
***
#### **Silently** – *Automatic Background Generation*
* **Function:** The GST E-Invoice is generated **immediately after saving the transaction** without any prompts.
* Runs **in the background**, requiring no user input.
* The generated invoice can be viewed directly on the GST E-Invoice portal.
***
### **Summary Table**
| Mode | Automatic? | Best For |
| ------------ | ---------- | --------------------------------------------- |
| **None** | ❌ | Businesses preferring manual control |
| **Prompt** | Optional | When verification is needed before generation |
| **Silently** | ✅ | Fast, hands-free processing |
***
### **Recommendation**
* Use **None** if you want full control over when E-Invoices are generated.
* Use **Prompt** if you want the system to ask each time.
* Use **Silently** for high-volume, automated operations.

## 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://kb.logicerp.com/logic-erp-learning-hub-tutorials-and-best-practices/setups/configurations/sale-voucher-configuration/other-settings-2/generate-gst-e-invoice.md?ask=&goal=
```
`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.
