Check your GSTR-3B summary

What it shows

Go to Filing → GSTR-3B and choose the period. You get the summary figures for the month — your outward supplies and the tax on them, split the way the return expects.

It comes from the same invoices as your GSTR-1, so the two agree with each other by construction rather than by luck.

What it is not

It is a summary you check and hand over, not a filed return. Dukaaan does not submit 3B.

Table 4 shows one row and one row only: 4(A)(5), the GST your suppliers charged you on the purchase bills you entered. Every other row of Table 4 reads “Not computed”, because that is the truth — Dukaaan does not test section 17(5) blocked credits, does not work out Rule 42/43 or Rule 37 reversals, keeps no credit ledger, and takes no view on reverse charge or imports. The figure is before eligibility adjustments; confirm it with your CA before you file.

What it can do is show you which of your purchases your suppliers have not reported yet, so you know before you file. See “Reconcile your purchases with GSTR-2B”.

Two more things it does not cover. Reverse charge: a purchase where you pay the GST instead of your supplier cannot be recorded as one, so row 3.1(d) and row 4(A)(3) are yours and your CA’s to fill. Compensation cess: Dukaaan never works it out. It has been nil since 1 February 2026, and on an older invoice, or a note against one, the cess you type in is carried exactly as entered.
