18 June 2025 Dear Experts,
I am facing a challange while I accept invoice on IMS. There is no column in IMS, where date of GSTR-1 filling is mentioned.
Generally, I do take action and generate GSTR-2B about 16th or 17th of Each month. But sometimes, I find difference between total of GSTR 2B summary and accepted invoice. On checking with auto generated 2B, I found that the difference is due to late filling (after 11th, cut off date) of GSTR-1 by the vendor.
So, I want to know whether it is portal issue or my working method ?
Please guide with best solution.

12 August 2025 Why the mismatch happens:
GSTR-2B is auto-generated based on GSTR-1 filed by your vendors up to the cut-off date (usually 11th of the next month).
If a vendor files GSTR-1 after the 11th, their invoices will not appear in that month’s GSTR-2B but will appear in the next month’s 2B.
Your IMS shows invoices you accept but does not show the GSTR-1 filing date of your vendor, so you don’t see which invoices got included or excluded based on filing date.
Is it a portal issue or working method?
This is not a portal glitch but how GSTN system generates 2B based on cut-off dates.
IMS not showing filing date is a limitation, but you can cross-verify on the GST portal under your vendor’s GSTR-1 status to check filing dates.
Best practices to handle this:
Check vendor filing date:
Before accepting invoice in IMS, check if vendor has filed GSTR-1 before 11th.
You can do this by viewing vendor’s GSTR-1 status on GST portal.
Reconcile GSTR-2B monthly:
Understand that invoices filed late will appear in next month’s GSTR-2B, causing timing differences.
Use cut-off date for accepting invoices:
Accept invoices in IMS only after confirming vendor’s filing status or after the 11th cut-off to avoid mismatch.
Maintain communication with vendors:
Request vendors to file GSTR-1 timely to ensure smooth ITC flow and reconciliation.
