The document summary in GSTR-1 is the table that lists the total count and the serial number range for every category of document you issued during the period — invoices, revised invoices, credit notes, debit notes, and other prescribed document types — including any that were cancelled. It exists so the GST system can check that your invoice numbering is sequential and complete, not just that the tax values add up. This guide explains what belongs in it and how to fill it without gaps.
What Is the Document Summary in GSTR-1?
The document summary is a table in GSTR-1, commonly referred to as Table 13, that records the number of documents issued and their serial number range for each document category in the return period, including cancelled documents. Unlike the B2B or B2C tables, it does not report values or tax amounts — it reports counts and serial ranges, so the portal can verify that no invoice number in your declared series is unaccounted for.
Which Document Types Appear in the Document Summary?
| Document Type | What It Covers |
|---|---|
| Invoices for outward supply | Regular tax invoices issued for B2B and B2C sales |
| Revised invoices | Invoices issued to revise supplies made before obtaining registration, where applicable |
| Debit notes | Notes raised to increase a previously invoiced value |
| Credit notes | Notes raised to reduce a previously invoiced value, including sales returns |
| Receipt vouchers | Vouchers issued for advances received where advance receipt reporting applies |
| Payment vouchers | Vouchers issued for payments under reverse charge, where applicable to the taxpayer |
| Refund vouchers | Vouchers issued when an advance is refunded without a supply taking place |
Why Does GSTR-1 Require a Document Summary at All?
The document summary exists to let the GST system confirm that your document numbering for each series is continuous and accounted for, separately from confirming that your reported sales values are correct. Two businesses can report identical B2B and B2C totals while one has gaps in its invoice numbering and the other does not — the document summary is what surfaces that difference.
Do You Need to Report Cancelled Invoices in the Document Summary?
Yes. Cancelled invoices still count within the total number of documents issued and within the serial number range for their series; they are reported separately as cancelled so the range accounts for every number, including the ones that were voided rather than sent to a buyer.
How Do You Fill the Document Summary Table Correctly?
- List every document series you used in the period — for example, a separate invoice series per sales channel or per GSTIN branch.
- For each series, record the starting and ending serial number actually used in the period.
- Count the total documents issued in that series, and separately count how many of those were cancelled.
- Repeat for credit notes, debit notes, and any vouchers relevant to your business.
- Check that the serial range for each series has no unexplained gap before submitting.
What Happens If Your Invoice Numbers Aren't Sequential?
A gap in a declared serial number range without a matching cancelled-document entry can draw scrutiny, since it suggests a document exists that was not reported anywhere in the return. If you skip numbers deliberately — for example, across parallel systems — either avoid overlapping series or be ready to account for the gap as cancelled documents in the document summary.
What Are Common Document Summary Errors?
- Forgetting to include a document series used by only one sales channel or branch.
- Reporting a serial range that does not match the invoices actually issued in the period.
- Leaving out cancelled invoices, which creates an unexplained gap in the range.
- Mixing two unrelated numbering series into one row instead of reporting them separately.
Does the Document Summary Affect Your Buyers' Input Tax Credit?
The document summary itself does not carry tax values, so it does not directly change the input tax credit visible to your buyers in their GSTR-2B — that comes from the B2B invoice table. However, an inconsistent or incomplete document summary can flag your GSTIN for review, which indirectly affects the reliability buyers place on your filings over time.
How Should Multi-GSTIN and Multi-Channel Sellers Organise Document Series?
If you sell through more than one marketplace or hold more than one GSTIN, keep a distinct, clearly labelled invoice series for each combination of channel and registration rather than letting numbering overlap between them. A single shared series across two GSTINs, or across a marketplace channel and an offline counter, makes it difficult to report an accurate serial range for either one in the document summary, since the numbers used by one channel interrupt the sequence expected from the other.
Does the Document Summary Need to Match Your Accounting Records?
Yes, in practice the serial ranges and counts you report in the document summary should be traceable back to your own invoice register or accounting software, since that is the source you would use to explain any gap if a query arises. Keeping your accounting records and your GSTR-1 document summary aligned as you go, rather than reconstructing the numbering at filing time, makes this far less error-prone.
How OneBooks GST Builds the Document Summary Automatically
OneBooks GST tracks every invoice, credit note, and debit note generated or imported for a GSTIN and uses that same record to build the document summary alongside the B2B, B2C, and HSN tables, so the serial ranges reported match what was actually issued rather than being reconstructed by hand at filing time. When sales come in from Amazon, Flipkart, Meesho, or other supported marketplaces, or through direct invoice entry, OneBooks GST keeps the numbering and cancellation status attached to each document so the document summary in your GSTR-1 automation workflow reflects it correctly. The completed return, document summary included, exports as GSTR-1 JSON for the GST portal or into Tally XML, CSV, Excel, Miracle, and Profit NX formats. If you are setting up invoicing for the first time, the direct invoice entry feature under accounting software in OneBooks GST helps keep your numbering series consistent from the start.
For the value-based summary in the same return, see our guide on the GSTR-1 HSN summary, and if you need to correct a document already reported, read how to amend GSTR-1 after filing.
Frequently asked questions
What is the document summary in GSTR-1?
The document summary is a table in GSTR-1 that records the count and serial number range of every document type you issued in the period, including cancelled ones, so the portal can verify your numbering is complete and accounted for.
What document types go into the document summary?
It covers invoices for outward supply, revised invoices, credit notes, debit notes, and where applicable, receipt, payment, and refund vouchers, each reported with their own serial number range.
Do cancelled invoices need to be reported in the document summary?
Yes, cancelled invoices are still counted within their series' serial number range and reported separately as cancelled, so the range accounts for every number used, including voided ones.
Why does GSTR-1 need a separate document summary from the sales tables?
The document summary checks that your invoice and note numbering is sequential and complete, which is a different check from whether your reported sales values are correct. A business can have accurate totals while still having gaps in its numbering.
What happens if there's a gap in my invoice numbering?
An unexplained gap in a declared serial range can draw scrutiny, since it suggests a document was issued but not accounted for. Gaps should be explained through the cancelled-document count in the same series.
Does the document summary affect my buyers' ITC?
Not directly, since it does not carry tax values — that comes from the B2B invoice table. But an inconsistent document summary can flag your GSTIN for review, which can indirectly affect how buyers view your filings.
