5 best GST refund tools and workflows for service exporters

There is no honest single ranking because these options do different jobs. The GST portal provides the filing route, Gen GST is operator software, MyGSTRefund advertises a platform-plus-service model, Zoho Books is a source system, and Fast GST Refund is a self-serve automation product in development.

This comparison covers accumulated-ITC refunds on exports of services without payment of tax under LUT. We reviewed public material but did not test authenticated competitor products. Fast GST Refund publishes this article; early access to our product is not open yet.

The five options at a glance

Option	Operating model and status	Refund role	Important limitation
GST portal + official utilities	Available official route	Statement 3 and Annexure B upload workflow	You prepare, reconcile and validate the underlying data
Gen GST	Available practitioner software	A public walkthrough documents Annexure B import and JSON generation	Confirm the licensed package and full service-export workflow
MyGSTRefund	Advertised platform plus managed service	Public claims include calculation, filing, tracking and Statement 3	Confirm what is automated, what experts do and the written fee
Zoho Books	Available accounting source system	Invoice/bill exports and GSTR-2B reconciliation	It is not a complete refund product
Fast GST Refund	Early access is not open yet	Self-serve reconciliation, computation and statement preparation	The current site explains the planned workflow

1. GST portal and official offline utilities

The official route is appropriate when transaction volume is manageable and the claimant or adviser can maintain a controlled invoice-level working. It avoids another vendor and produces the formats the portal expects.

The utilities do not automate the underlying preparation. Export invoices still need to be matched to BRC/FIRC evidence, inward supplies and reversals reviewed, the refund calculated, and ledger limits checked. The portal manual documents separate Statement 3 and Annexure B upload steps. GST portal refund manual.

2. Gen GST

Gen GST belongs on a CA or tax-team shortlist because SAG Infotech publishes a concrete Annexure B workflow: select the client and period, import GSTR-2B or government Excel data, complete missing information and generate JSON.

That is evidence of an operator-led workflow, not proof of a hands-off service-export refund. Ask for a real demonstration covering Statement 3 receipts, Rule 89(4), review controls and the precise licensed package. Read the Gen GST review and Fast GST Refund vs Gen GST.

3. MyGSTRefund

MyGSTRefund advertises a broader outcome: eligibility checks, calculation, filing, tracking, reconciliation and expert support. Its About page describes a hybrid of SaaS automation and performance-based services.

That operating model may suit an exporter who wants a provider involved. Request a written fee, responsibility split, access policy and post-filing scope. The public material does not by itself establish which steps are automated or how a particular claim will perform. See the MyGSTRefund review.

4. Zoho Books

Zoho Books can export invoices and bills and reconcile GSTR-2B. It can reduce extraction work when the books are complete, but it should not be mistaken for the refund product itself. Bank evidence, receipt allocation, earlier claims and several tax decisions live outside a normal accounting export. Zoho invoice export, Zoho GSTR-2B reconciliation.

Follow the Zoho Books export guide to preserve useful source keys.

5. Fast GST Refund: self-serve preparation automation

Fast GST Refund brings the preparation workflow into one self-serve workspace. It is designed to:

• import accounting, return, invoice and receipt data;
• reconcile export invoices to realisation evidence and purchases to GST records;
• surface missing, conflicting and judgement-dependent rows;
• prepare a traceable Rule 89(4) working; and
• generate and validate Statement 3 and Annexure B outputs for final review.

Availability note: early access is not open yet, and pricing has not been announced. The current two-question flow shows the preparation path relevant to your claim and provides useful guidance in the meantime. That guidance is not the product.

One possible implementation is an isolated automation workspace that can operate spreadsheets and official offline utilities while preserving a per-claim audit trail. That is an architecture under consideration, not a launched capability.
