How Fast GST Refund works
The goal is to automate the repetitive preparation chain: import records, reconcile export invoices and receipts, compare inward supplies with GST data, isolate exceptions, calculate a traceable Rule 89(4) working, and prepare validated Statement 3 and Annexure B outputs.
This is not a checklist product. Early access is not open yet. The current flow shows the preparation path relevant to a visitor’s claim and provides useful guidance in the meantime.
One possible technical route is an isolated per-claim workspace that can operate Excel, official offline utilities and other desktop tools used in the workflow. That possibility should not be confused with a launched integration or a promise of direct GSTN filing.
Gen GST’s documented workflow
SAG Infotech’s walkthrough shows an operator selecting the client and period, importing Annexure B data from GSTR-2B or a government Excel file, completing missing fields and generating JSON. The article notes that some information absent from GSTR-2B still requires manual entry.
That specificity makes Gen GST relevant to a working CA practice. It does not establish how every part of a service-export claim is handled. Ask the vendor to demonstrate invoice-to-receipt matching, partial receipts, Rule 89(4), ledger limits, Statement 3, amendments, review evidence and the final filing hand-off.

Which should you choose?
Use Gen GST or another currently available route if you need production software today and its pilot passes your requirements. Consider Fast GST Refund if the focused self-serve direction matches your needs—but do not treat it as an available replacement until launch.
