How to Use Bill Number as Invoice Number for Journal Sales in GST Returns?
In this tutorial, we will learn how the "Use Bill Number as Invoice Number in JV Sales" feature works during GST Return generation in Logic ERP. This option allows the system to use the Bill Number from Journal Sales transactions as the Invoice Number in GST Returns instead of the Journal Sales document number.
Objective of This Feature
Use Bill Numbers as Invoice Numbers in GST Returns.
Improve invoice number consistency with business documents.
Align GST reporting with actual billing references.
Simplify GST reconciliation and verification.
Provide flexibility in Journal Sales reporting.
Access to GST Returns Configuration
Navigate to Reports/Queries and then Sale Registers.
Select GST Reports/Returns.
Open GST Returns Module.
Click on Configuration and open Configuration Settings 2.
Locate the option labeled as:
"Use Bill Number as Invoice Number in JV Sales"

By default, this feature is disabled.
Understand the Journal Sales Transaction
Before generating the GST Return, let's review an existing Journal Sales entry.
Example
A Journal Sales transaction contains:
Document Number
JS10
Bill Number
5522

Observation
The Journal Sales Document Number is JS10.
The Bill Number entered in the transaction is 5522.
Generate GST Return with the Feature Disabled
Action
Open the GST Returns Module.
Select the required Return Type.
Choose the required Return Period.
Click Generate.

Result
Since the feature is disabled:
The Invoice Number column displays the Journal Sales Document Number.
In this example, the Invoice Number appears as: JS10
The system uses the Journal Sales voucher number as the invoice reference.
Generate GST Return with the Feature Enable
Action
Return to the GST Returns Configuration window.
Enable the option: "Use Bill Number as Invoice Number in JV Sales"
Save the configuration.
GST Return Again
Select the same Return Type.
Select the same Return Period.
Click Generate.
Result
After enabling the feature:
The Invoice Number column now displays the Bill Number from the Journal Sales transaction.
Instead of showing: JS10
The system displays: 5522

Comparison
Disabled
Journal Sales Document Number (JS10)
Enabled
Journal Sales Bill Number (5522)
Key Benefits
Uses actual business bill references in GST Returns.
Improves consistency between accounting and GST records.
Simplifies invoice tracking and reconciliation.
Reduces confusion caused by internal voucher numbering.
Enhances GST reporting accuracy.
Best Practice Tips
Enable this feature if your organization uses Bill Numbers as primary customer-facing invoice references.
Ensure Bill Numbers are entered correctly in Journal Sales transactions.
Verify Invoice Numbers before generating GST JSON files.
Maintain a consistent Bill Numbering system for accurate GST reporting.
Final Outcome
When the "Use Bill Number as Invoice Number in JV Sales" feature is enabled, Logic ERP automatically uses the Bill Number from Journal Sales transactions as the Invoice Number in GST Returns. When disabled, the system uses the Journal Sales Document Number instead. This provides greater flexibility and helps align GST reporting with actual business invoice references.
