How does GST reconciliation work in Marg ERP (GSTR-1 / GSTR-2A / GSTR-2B)?

Marg ERP's GST module reconciles your outward and inward filings against what's recorded in the software without repeated portal logins. For GSTR-1, go to GST > GST Register & Returns > GSTR-1, load the JSON downloaded from the portal, and click Reconcile to compare it against invoices created in Marg. For GSTR-2A, Marg pulls purchase data via the GST portal's API (enabled once from your portal login under Manage API Access) so it can check the sales your suppliers uploaded against what's showing as your purchases on the portal.

GSTR-1 reconciliation

Marg's help centre documents this as comparing what was uploaded on the GST portal against invoices created in Marg.

Go to GST > GST Register & Returns > GSTR-1.
Select the reconciliation period and click Show to view the GSTR-1 summary.
Click Reconcile GSTR-1 and select the JSON file downloaded from the GST portal.
Review the invoice-level details shown — GSTIN, invoice number, invoice date, taxable amount, cess amount and place of supply.
Click Reconcile — matched invoices are colour-coded, so you can see at a glance what's matched, absent from Marg, pending upload, or mismatched.

GSTR-2A reconciliation

GSTR-2A is inward supplies (purchases). Marg's own documentation describes the point of this feature as letting you "check that the sales uploaded by the party and the purchases displayed to the user in GST Portal are matched or not" — without logging into the portal every time.

In the GST portal (gst.gov.in), go to My Profile > Manage API Access, enable API Request, and confirm with the OTP sent to you.
In Marg, go to GST > GSTR Settings to connect using that API access.
Open GST > GSTR 2A-2B Reconciliation, select GSTR-2A, choose the period, and click Show.
Review the matched entries — Marg's help centre notes matched invoices display in green.

FAQs

Do I need to log into the GST portal every time I reconcile in Marg?

No — once API access is enabled from your GST portal profile and connected in Marg under GST > GSTR Settings, Marg can pull the data without a fresh portal login each time.

What does a colour-coded status mean in Marg's GSTR-1 reconciliation?

Marg's help centre describes the statuses as: matched invoices, invoices uploaded to the portal but not created in Marg, invoices created in Marg but not yet uploaded to the portal, and invoices where the values differ between the two.

Is GSTR-1 reconciliation the same as GSTR-2A reconciliation in Marg?

No — GSTR-1 reconciliation in Marg compares your outward supplies against what you uploaded to the portal, while GSTR-2A reconciliation compares inward supplies (purchases) your suppliers reported against what's recorded in Marg, and they're reached from separate menus.
