GST return filing that comes out of your own books
The returns are not a separate exercise in Zembook. GSTR-1 and GSTR-3B are computed from the vouchers you already entered and export as JSON the portal accepts, so correcting an invoice corrects the return - there is no second place to keep in step.
GSTR-1 and GSTR-3B
Both export as portal-ready JSON. Because both are derived from the vouchers rather than typed into a summary, the figures cannot disagree with your books - and when they look wrong, you can drill from the figure to the ledger to the individual bill behind it.
Zembook produces the file and you upload it on the portal. It does not file on your behalf, and no software should claim to without holding your portal credentials.
GSTR-2B reconciliation is the one that pays for itself
Download the portal's own 2B and Zembook matches it line by line against the purchases you entered. What comes out is the list that matters: which supplier has not filed your bill, and therefore which input credit you are about to claim and lose.
That is money, and it is invisible until somebody actually compares the two.
Reverse charge, and the rest of the statutory load
A purchase under reverse charge is marked on the voucher and reported separately in 3B, which is where RCM most often goes missing entirely.
There is a TDS register with sections and thresholds as an editable master, income-tax computation from the year's books, a depreciation run that writes its own entries, and a fixed asset register.
e-Way Bill and e-Invoice
e-Way Bill exports in the NIC format including the portal's own UQC codes - KGS not KG, DZN not DOZ - which is the small detail that gets a JSON rejected. e-Invoice exports for IRN generation.
Questions people ask
- Does Zembook file my GST return for me?
- No. It produces the portal-ready JSON from your books and you upload it. Filing on your behalf would need your portal credentials, and software that claims to do it without them is describing something it is not doing.
- What does GSTR-2B reconciliation actually tell me?
- Which of your purchase bills your suppliers have not filed. That is input credit you would otherwise claim and then lose, and it is not visible anywhere until the portal's 2B is matched against your own entries.
- Is reverse charge handled?
- Yes - marked on the purchase voucher and reported separately in GSTR-3B rather than folded into ordinary input tax.
