Tax & Compliance · THE NO-PANIC PLAN
Reconcile purchase invoices against GSTR-2B before filing
GSTR-2B is a read-only, auto-drafted statement built from supplier and other reported information. It is an important reconciliation input, not a substitute for the business?s books, original invoices or the current GST law. This workflow helps an Indian registered business compare records, investigate mismatches and keep an auditable resolution trail. Use the GST portal?s current return-period instructions and have a qualified tax professional determine eligibility, reversals and filing treatment. Nirmion?s GST Invoice Checker checks key invoice fields and basic GSTIN structure only; it cannot validate a GSTIN against the live portal, reconcile ledgers or decide input tax credit eligibility. Avoid entering bulk or confidential records into a public tool.
MISSION Reconcile a registered Indian business?s purchase records with the GST portal?s GSTR-2B and resolve invoice differences before an authorized person finalizes the return.

Download the period?s books and GSTR-2B from authorized systems; standardize document identifiers and amounts; compare invoice, debit/credit-note and supplier details; investigate missing, amended, duplicate or inconsistent records through the GST portal and supplier; then document review and reconcile the approved return figures without treating a match as automatic eligibility.
YOUR CHECKLIST, WITH FEWER DRAMATIC SIGHES
One step at a time.
Follow the order below. If a step names a Nirmion tool, its link is right there with it.
- 01
Collect the same-period records from authorized sources
Choose the GST registration and return period, then export the purchase register and relevant expense/inward-supply records from the accounting system. Sign in through the official GST portal to download the matching GSTR-2B and, where applicable, inspect the Invoice Management System (IMS) dashboard and supplier-filed amendments. Retain the download date and source file names in a restricted work folder. Preserve original invoices, debit notes, credit notes, import documents and payment or receipt evidence under your records policy. GST portal guidance describes GSTR-2B as a read-only auto-drafted statement derived from supplier filings and other sources; it should be reconciled with your own books. Use authorized accounts and do not place credentials or full confidential ledgers in the Nirmion tool. (Sources 1, 2, 5)
- 02
Standardize records and prevent duplicate matching
Create a working comparison keyed to the relevant GST registration, supplier GSTIN, normalized invoice or debit-note number, document date and financial period. Keep original values alongside normalized values so punctuation or leading-zero cleanup does not overwrite evidence. Separate document types, amendments, credit notes, reverse-charge items, imports and other categories instead of matching unlike records as if they were the same transaction. Flag duplicate rows and confirm whether they are true duplicate documents, repeated exports or an amendment. The GST portal?s GSTR-2B documentation lists separate document categories and advises reconciliation with books; never claim the same document twice. Limit the comparison file to staff who need it and retain it according to your organization?s tax-record policy. (Sources 1, 2, 5)
- 03
Compare invoice fields and classify every difference
Compare supplier GSTIN, document number and date, taxable value, tax amounts, place-of-supply or tax-head details where relevant, document type, amendment status and credit/debit-note treatment. Classify each record as matched, absent from books, absent from GSTR-2B, value/field mismatch, amended, duplicate, or requires eligibility review; assign an owner and evidence link. For an individual authorized invoice, Nirmion GST Invoice Checker (tool 209) can check key Indian GST invoice fields and basic GSTIN structure. It does not connect to the GST portal, establish registration status, verify a supplier return or decide tax treatment. Do not treat a green field check or a GSTR-2B match as proof that input tax credit is legally available. (Sources 2, 3, 4)
- 04
Resolve supplier and portal differences before recording a decision
For a missing or incorrect supplier document, contact the supplier through a verified business channel and share only the information needed to correct it. Check whether the supplier filed or amended the relevant document, then refresh or review the appropriate GST portal statement and IMS status using current official instructions. Do not silently change your books to force a match, create an invoice on a supplier?s behalf or assume a discrepancy is resolved because a request was sent. Record the response, evidence, owner, deadline and period in which the correction appears. Escalate classification, blocked-credit, reversal, reverse-charge or legal questions to the authorized tax professional; the applicable provisions and portal behavior can change. (Sources 1, 2, 4, 5)
- 05
Review the return figures and preserve a closeout trail
Before the authorized filer submits the return, reconcile the final proposed figures to the books, GSTR-2B, resolved differences, credit/debit-note treatment and the current GST rules applicable to the entity. Confirm that no document is counted twice, required reversals or reverse-charge treatment were reviewed, and unresolved items have an explicit disposition approved by the responsible reviewer. Keep the reconciliation, source exports, supplier correspondence, approval, filed-return acknowledgement and any later correction trail in the approved records system. The CBIC Act and Rules describe statutory requirements, but a workflow checklist or invoice-field tool cannot decide a particular taxpayer?s eligibility. Use the GST portal?s latest guidance and obtain professional review when facts or treatment are uncertain. (Sources 1, 3, 4, 5)
