# How should manufacturers and distributors reconcile GSTR-2B and IMS?

**Question:** How should manufacturers and distributors prepare GSTR-2B and IMS reconciliation?

**Answer:** Compare the purchase register for the relevant GST registration with portal records using supplier GSTIN, document number, document type, date and tax amounts. Separate matched records from missing invoices, differences, duplicates and credit-note issues. Give each exception an owner, review permitted IMS actions with the accountant, and retain the final reconciliation used for filing. A matched invoice is evidence for review; it does not establish input tax credit eligibility by itself.

## Key takeaways

- Reconcile by GST registration and period, retaining original invoice identifiers and source downloads.
- Keep operational mismatch labels separate from actions submitted in the GST portal.
- Read October 2025 IMS changes alongside the original guidance; pending options have conditions and time limits.
- Have the filing team verify eligibility and final figures, and preserve the reviewed version with its supporting evidence.

## Define the scope before comparing records

A manufacturer may purchase ingredients, packaging, maintenance services and equipment through different teams. A distributor may handle purchases, returns and supplier schemes across several warehouses. Start by identifying the GST registration, reporting period and source systems covered by the reconciliation. Name the person preparing it, the person following up with suppliers and the accountant responsible for the filing decision.

> This is a records-preparation checklist. The official sources below describe GST portal behaviour and dated changes; confirm the current rules and your business's treatment with your accountant before filing. No universal filing deadline, GST rate or ITC entitlement is assumed here.

Save the purchase register and portal downloads with their period and download time. If you have several registrations, avoid pooling them into an unexplained total. A supplier can issue invoices to different GSTINs in the same group, and a company's accounting date can differ from the supplier's reporting period. Retaining those distinctions prevents a timing or registration issue from becoming an incorrect accounting adjustment.

## Prepare a consistent matching sheet

_Suggested fields for the working reconciliation, not a replacement for the portal's document schema._
| Field group | Include | Why it helps |
| --- | --- | --- |
| Identity | Recipient GSTIN, supplier GSTIN, document type and original number | Avoid mixing suppliers, registrations or credit notes |
| Timing | Document date, book-entry date, relevant portal period | Explain cut-off and reporting differences |
| Amounts | Taxable value and each applicable tax component | Identify what differs instead of comparing only gross totals |
| Evidence | Invoice, receipt or service evidence, related note and correspondence | Support investigation of the actual transaction |
| Review | Mismatch reason, owner, next date, decision and reviewer | Keep exceptions accountable through filing |

You can create a separate normalised matching key to spot spaces or formatting differences in invoice numbers, but preserve the original value. Never overwrite the source identifier just to force a match. Likewise, an import should distinguish an invoice from an amendment to that invoice. Keep an import reference so that reloading the same source does not create a second purchase entry.

## Separate mismatches into useful work queues

- In books but absent from the relevant portal download: check supplier identity, reporting period and document details, then follow up with evidence.
- In portal records but absent from books: investigate whether the purchase belongs to this registration and whether an invoice or goods-receipt record is missing.
- Different amounts: compare taxable value and tax components, and check the original invoice and any amendment.
- Possible duplicate: review document identifiers and import history before changing an accounting record.
- Credit note or return difference: connect the note to the original purchase and prior accounting or tax treatment.

These are internal investigation labels. They do not instruct a user to accept, reject or keep a document pending in IMS. A portal action has consequences beyond a spreadsheet status, so let the filing team decide the permitted action after reviewing the evidence. Give high-value and ageing exceptions a review date instead of leaving them in a generic mismatch bucket indefinitely.

## Use current IMS guidance with its date and scope

The [GSTN IMS FAQs issued in September 2024](https://tutorial.gst.gov.in/downloads/news/final_faqs_on_ims_22_09_2024.pdf) describe how recipient actions affect portal processing. They explain that no-action records are treated as deemed accepted and that changes after draft GSTR-2B generation require recomputation before filing GSTR-3B. A system status is not a substitute for checking the underlying invoice and eligibility.

Read that baseline with [GSTN's changes from the October 2025 tax period](https://tutorial.gst.gov.in/downloads/news/creative_faq_on_gstr9_for_24_25_dt_15_oct_25_v6_final.pdf). Those FAQs extend pending actions to specified credit notes and amendments, introduce an ITC-reduction declaration for specified cases and describe remarks. The newly covered pending records have a limited window linked to the applicable period and filing frequency. Do not assume every document can remain pending indefinitely or apply one action to every mismatch.

Before a bulk action, filter the actual records, confirm the reason for grouping them and have the reviewer inspect a sample. Keep the list of affected document identifiers with the decision. If a supplier later changes a record or your team receives new evidence, review the affected items again rather than relying on the status in an older export.

## Work through a mismatch without inventing an adjustment

In an illustrative reconciliation, the books show total recorded purchase tax of ₹50,000 and the compared portal records show ₹45,000. Investigation identifies a books-only invoice with ₹4,000 tax and a separate ₹1,000 amount difference. The arithmetic bridge is ₹45,000 + ₹4,000 + ₹1,000 = ₹50,000. This explains the difference being investigated; it is not an instruction to claim ₹50,000 of credit.

Attach the missing invoice to a supplier follow-up and record the response. For the amount difference, compare the actual document and any amendment with both systems. A data-entry correction requires its own evidence and approval. Do not create a balancing purchase, change a tax amount or move a date solely to make two totals agree. Keep the bridge open until the reviewer can explain what happened and which period or record is affected.

## Review returns and credit notes alongside the original purchase

Food manufacturers and distributors often deal with damaged goods, quality rejections, short supplies and commercial adjustments. Keep the return or claim evidence with the supplier's credit note and the original invoice. Check whether the commercial adjustment has actually been recorded and whether the filing team already dealt with related credit in a previous period. Similar-looking totals can hide different transactions.

GSTN's October 2025 FAQ provides specific treatment for declaring ITC reduction where credit was not availed or was already partly reversed. Ask the accountant to review those conditions using the previous filing evidence before selecting the applicable option. Keep that evidence attached to the working paper so a later reviewer can understand the decision without reconstructing it from emails.

## Close the review with a reproducible evidence pack

1. Record the GST registration, period and version of every source export used.
2. Save the comparison, mismatch explanations and supporting supplier documents.
3. Record reviewed portal actions and check whether the working comparison needs refreshing.
4. Have the filing team verify eligibility, reversals, exclusions and the final figures.
5. Retain the approved reconciliation and filing evidence; carry unresolved items into a dated follow-up list.

If purchases are entered after the review, identify which records changed and return the affected reconciliation to the reviewer. Mark the superseded working copy so another team member does not use it for filing. An evidence pack should make it possible to reproduce the numbers and explain decisions, while keeping invoice and taxpayer data accessible only to people who need it.

## Evaluate software against your purchase exceptions

Use a sample containing a clean invoice, a books-only invoice, a portal-only record, a duplicate, an amendment and a supplier credit note. Check that imports retain source numbers and that the exception report can be explained by the accounts team. Measure time spent resolving differences, not just the number of rows marked matched. Demonstrate a revised import too, because a workflow should remain understandable after records change.

The [Naffo GST solution page](/solutions/gst-software) is a starting point for discussing your purchase and reporting workflow. Confirm the supported imports, reports and portal interaction for your actual setup during a [demo](/book-demo). This checklist does not claim that Naffo files returns, synchronises IMS actions or establishes ITC eligibility automatically. Connect the monthly review with your [payment and cash-flow process](/blog/payment-reconciliation-cash-flow-small-business) so supplier disputes and expected payments remain visible.

## Frequently asked questions

### Does a matched invoice guarantee that input tax credit can be claimed?

No. Matching establishes agreement between specified records. The filing team still needs to verify the applicable eligibility conditions, supporting documents, exclusions and reversals for the business before determining the claim.

### Should every missing or mismatched invoice be rejected in IMS?

No. First investigate the registration, period, source document and reason for the difference. An internal mismatch label is not a portal instruction. The accountant should determine the permitted action after reviewing the transaction.

### Can all credit notes be kept pending indefinitely?

No. The GSTN October 2025 FAQ describes specified records and a limited pending window tied to the applicable period and filing frequency. Verify the document's conditions and current portal guidance before choosing an action.
