E-invoice for credit notes and debit notes: Reporting workflow

What is an E-invoice

The electronic invoice, also known as an e-invoice, refers to a goods and services tax invoice that has received electronic confirmation from the Invoice Registration Portal (IRP). Instead of preparing the invoices on the government portal, companies prepare them with the help of the ERP or GST compliant billing systems and send them to the IRP for authorization. Therefore, the generated invoices will fulfill the requirements of GST law and ensure precision. The following transactions are carried out once the invoice has been authorized:

Invoice Reference Number (IRN)
JSON and QR Code signed by digital signature
Validation status

After the e-invoice is created, it will automatically be transmitted to the GST and e-way bill systems. Thus, it eliminates the need for data input and complies with tax regulations.

Understanding credit notes and debit notes

The issuance of credit notes and debit notes is one of the effects of GST on businesses when they need to change the amount of tax charged in invoices already issued.

Credit note

Credit notes can be issued in several situations:

When goods are returned back by a customer
When goods are damaged
When it is necessary to reduce the value of the invoice
When there is an overcharge of GST
When discounting takes place after invoice is issued
When the quantity supplied decreases

Debit note

A debit note can be drawn in cases like:

When the invoice amount needs to be increased
When goods are supplied additionally
When GST has been undercharged
When there is a mistake in pricing
When the quantity supplied increases after invoicing

Both documents are designed to change the invoice issued and need to reference it correctly.

Are credit notes and debit notes covered under e-invoicing?

If your company is subject to the GST e-invoicing requirement, you should assure that all credit notes and debit notes issued for B2B transactions are reported to the Invoice Registration Portal. Every credit/debit note will have its own:

Invoice Reference Number (IRN)
QR code
Digital signature

Only when IRN is generated successfully will these documents become valid.

E-invoice reporting workflow for credit notes and debit notes

The report is based on a pre-defined workflow.

Step 1: Generate credit/debit note

Create the credit/debt note with the help of your accounting software. Such a note contains:

GST registration number of the supplier
GST registration number of the receiver
Invoice reference number
Invoice date
Referring to the original invoice
Value of the transaction
GST details
Reason for a credit/debit note.

Step 2: Create the JSON file

A document will be in the format of GST e-invoice JSON. It has following required fields:

Type of a document
Reference of an invoice
GST details
Breakdown of taxes
HSN codes and names of the items

Step 3: Upload the file to Invoice registration portal

JSON file will be uploaded through the following systems:

Integration with ERP
GST Suvidha Provider (GSP)
API integration
Third parties providing services of e-invoicing

Step 4: Validation at IRP

IT system validates the following:

Correctness of the GSTIN
Duplicate document numbers
All required fields
Calculation of tax
Overall format of the invoice
Complying with the schema

If the validation fails, the document will be returned for correction before re-submission.

Step 5: IRP generates IRN

Moreover, a system will produce:

Invoice Reference Number (IRN)
Signed JSON
QR
Digital signature

This credit or debit note thus becomes a valid GST document.

Step 6: GST portal updates

The authenticated details are automatically transmitted to:

GST Portal
Supplier records
Recipient records
E-way bill system (if needed)

This reduces manual reporting work.

Step 7: Keep business records

Business entities must keep safe:

Original credit/debit note
IRN
QR Code
Signed JSON
GST reporting information

These are necessary during GST audits and assessments.

Information required for reporting

A credit and debit note usually contains necessary details such as the details of suppliers, details of recipients, GSTIN of both, original invoice number with date, credit and debit note number, document date, taxable value, applicable CGST, SGST, IGST, and Cess (if applicable), HSN code, item description, quantity, unit price, total invoice amount and reason for adjustment. Including these particulars ensures GST reporting, reconciliation with the original invoice, and compliance with e-invoicing requirements.

Common reasons for issuing credit notes

Credit notes are mainly issued in case of:

Returns
Faulty merchandise
Wrong invoicing
Extra tax imposed
Sale rebates
Price cuts post sale
Cancellation of orders

Common reasons for issuing debit notes

Debit notes are mostly issued for:

Extra billing
Revised pricing
GST undercharge
Additional volume provided
Freight changes
Improved service
Contract changes

Benefits of reporting credit and debit notes through E-invoicing

Enhanced GST compliance

The usage of the Invoice Registration Portal (IRP) ensures that credit and debit notes meet the necessary GST rules and e-invoicing specification, thus reducing the risks of being fined for non-compliance and allowing businesses to comply with the law.

Enhanced transparency

Thanks to the fact that verified documents are available to both the seller and the buyer, companies can create a consistent record of transactions, which helps to enhance the level of transparency and avoid conflicts during the reconciliation.

Lowered error levels

By automating the verification process, businesses reduce the chances of making the mistakes related to manual data entry. Consequently, companies can generate reliable credit and debit notes without any concerns.

Faster reconciliation

As the data from e-invoices gets registered automatically with the GST system, businesses can perform the reconciliation of invoices, credit notes, and debit notes much quicker.

Easier audits

With the help of IRN and QR code, the process of GST audits is made much simpler for the businesses because they can easily find the evidence that tracks any transaction and adjustment.
