Start with the supply, then the reporting
GST work depends on what is supplied, by whom, to whom and where. A portal task should follow that analysis rather than substitute for it. We separate recurring return work from classification advice, refund claims and disputes.
A consistent record across systems
Sales registers, purchase records, payment records and portal information should be reconcilable. We define the GSTINs, periods, transaction volume and exceptions covered by the engagement.
Choose support for the task ahead
- Set up or change registrations: registration, multiple-registration coordination, cancellation and revocation.
- Maintain recurring records: return filing, input tax credit reconciliation, annual return and reconciliation, e-invoicing and e-way bills.
- Resolve a transaction question: classification and rate opinions, place-of-supply advice, reverse-charge review.
- Support exports and claims: LUT and export records, refund claim preparation.
- Investigate or respond: GST health checks, departmental audit support, legacy indirect-tax matters.
A recurring filing assignment and an advisory opinion have different inputs and outputs. If a transaction question is holding up a return or claim, identify it in the brief so its assessment and implementation can be coordinated.
Prepare your initial brief
Describe the business activity, operating states, number of registrations and periods involved. Explain whether you need recurring preparation, a one-off assessment or a response to an authority. For an existing problem, identify the affected transaction stream and the records available rather than sending only a net difference.
The written scope should identify who supplies the records, resolves factual queries, approves the working and handles payments. Detailed invoices and taxpayer records can be exchanged through the agreed secure channel after the assignment is defined.
