GST Compliance and Input-Tax-Credit Reconciliation
Coordinate GST data, GSTR-1 and GSTR-3B preparation, purchase-credit review, reconciliations, and documented open items across the filing cycle.
Discuss this serviceWhat this addresses
Sales and purchase data that does not reconcile to GST returns.
GSTR-2B differences and unclear input-tax-credit follow-up.
Multiple registrations, states, channels, or transaction types.
Late discovery of credit notes, reverse charge, classification, or documentation issues.
A sensible fit
Who this is suitable for
- GST-registered startups, MSMEs, and growing businesses.
- Businesses selling across states, marketplaces, or multiple channels.
- Teams with material vendor purchases and working-capital sensitivity to ITC.
- Companies replacing a filing-only process with a books-led review.
Signals to act
When to consider it
- Purchase ledger and GSTR-2B show recurring differences.
- GSTR-1, GSTR-3B, e-invoice, or accounting values do not align.
- A new state, product, service, marketplace, or transaction type is introduced.
- Management cannot see unresolved GST exposures before the due date.
Typical scope

Return preparation
Working papers and agreed preparation support for GSTR-1, GSTR-3B, and specified recurring returns.

Working sequence
How the engagement typically moves.
- 01
Collect and close data
Receive sales, purchases, notes, portal data, and relevant transaction support to an agreed cut-off.
- 02

Compare books, source schedules, GSTR-2B, prior returns, and tax ledgers; classify differences.

Submit authorised returns, retain evidence, and track unresolved vendor or prior-period matters.
Prepare well
Information typically required
- Sales and purchase registers with tax, state, customer or vendor, and invoice details.
- Credit and debit notes, advances, exports, reverse-charge, and adjustment schedules.
- GSTR-2B, electronic ledgers, prior returns, payment references, and registration details.
- E-invoice, e-way bill, marketplace, or branch data where applicable.
- Supporting tax invoices and explanations for unusual or disputed transactions.
Avoid preventable friction
Common risks to manage
- Claiming credit based only on internal books without checking eligibility and supplier reporting.
- Treating GSTR-1 and GSTR-3B as separate exercises instead of reconciling them.
- Using incorrect state, place-of-supply, rate, or transaction classifications.
- Carrying unresolved differences without owners, evidence, or ageing.
- Assuming a portal acceptance confirms the legal correctness of every position.
Scope clarity
What is not automatically included
Separate professional opinions, historical issues, authority matters, or specialist work are identified and scoped explicitly when relevant.
- GST registration, cancellation, refund claims, notices, audits, appeals, advance rulings, or litigation unless separately scoped.
- Legal opinions on complex classification, place of supply, valuation, or eligibility questions.
- Recovery of vendor action or authority approval of credits or refunds.
- Guarantees that a credit, refund, tax position, or return will be accepted without query.

Frequently asked
Useful questions before you begin.
Does GSTR-2B matching automatically determine eligible ITC?
No. Matching is an important control, but eligibility also depends on the nature of the purchase, documents, receipt, restrictions, payment conditions, and applicable law.
Can old GST differences be included in monthly support?
They can be assessed, but historical reconstruction and corrections may need a separate scope so routine current filings remain controlled.
Who approves the GST return?
The authorised business reviewer should approve the data and material positions. FiscalFlow’s process can prepare the review pack and highlight open matters, but the business remains responsible for complete information and authorisation.
Are refunds and notice responses part of recurring compliance?
Not automatically. They require separate factual analysis, documents, and authority interaction and should be scoped independently.
