File B2B invoices early with IFF (QRMP)

Under the QRMP scheme, upload B2B invoices for the first or second month of a quarter through IFF, so your buyers can claim input tax credit sooner.

If you file GSTR-1 every quarter under the QRMP scheme, the Invoice Furnishing Facility (IFF) lets you upload B2B invoices in the first two months of a quarter. Your buyers then see them and can claim input tax credit without waiting for your quarterly return.

Before you start

GST registration must be on in GST configuration.
To file on the portal from Arthlekha, link your GST portal account by OTP in GST configuration. Downloads do not need this link.
Set the Authorized Signatory PAN in the GST Filing Authority part of the Business Profile. The OTP goes to the mobile registered with that PAN.
Only invoices to customers with a GSTIN appear. Check the GSTIN on each customer.

What goes in IFF

Use IFF in the first or second month of a quarter, such as April or May. Check the GST portal for the IFF dates.
Only B2B invoices go in IFF. B2C sales, the HSN summary and the document summary always go in the quarterly GSTR-1.
Invoices filed in IFF are left out of the B2B table of the quarterly GSTR-1, so they are not uploaded twice.

Steps

Open Statutory (GST) > IFF (QRMP).
Pick the Month and Year. The period shows next to them.
Check the boxes at the top: PENDING (not in IFF yet), FILED IN IFF, and TOTAL TAXABLE (B2B IN MONTH).
Look through the list. Each invoice shows Pending or the IFF month it was filed in.
Tick the invoices you want to file. Tick the box in the header to select all pending invoices.
File in one of the three ways below.

File on the GST portal from Arthlekha

Click File on GSTN. The File IFF on GSTN window opens.
Click Prepare & request OTP. Arthlekha saves the invoices to the portal, asks the portal for the IFF summary, and sends an OTP to the signatory's mobile.
Type the OTP and click File with OTP. The OTP is valid for about 10 minutes. Click Resend OTP if it did not arrive.
The window shows the Acknowledgement Number (ARN) and date. Note the ARN.
The filed invoices are marked as filed in IFF for that month.

If you tick some invoices, only those are filed. If you tick none, all invoices in the list are filed.

Upload the file yourself

Click IFF JSON to download a file for upload on the GST portal. Click Excel for a spreadsheet of the same invoices.
Upload the JSON on the GST portal.

Downloading the JSON or Excel marks the pending invoices of that month as filed in IFF straight away. If you then do not upload them, unmark them as shown below.

Mark or unmark invoices by hand

Use this when you filed IFF directly on the portal.

Tick the invoices you filed.
Click Mark filed in IFF for the period. The button shows how many invoices are ticked.
To undo, tick the invoices and click Unmark selected. They go back to Pending and will be included in the quarterly GSTR-1 again.

Invoices carried over from last month

If an invoice from the first month of the quarter is still pending when you open the second month, it is shown with a from chip, such as "from 2026-04", and a yellow note. If ticked, it is filed with this month's IFF. Untick it to leave it for the quarterly GSTR-1.

Common problems

The list says there are no B2B invoices — none of the month's invoices has a customer GSTIN. Add the GSTIN on the customer and edit the invoice if needed.
Select at least one invoice — tick an invoice before clicking mark or unmark.
Authorized signatory PAN not set in Business Profile. — fill the GST Filing Authority part of the Business Profile.
GST account not linked. Go to Settings > GST Portal and link via OTP. — link the GST portal in GST configuration.
GST portal session expired. Re-link with OTP. — link again in GST configuration.
Enter the OTP sent to the signatory mobile. — type the OTP before clicking File with OTP.
An invoice was uploaded twice — check its status here. If it shows a month under IFF, it is already left out of the quarterly GSTR-1.
