GST Working File
The monthly GST workspace that sits between your billing software and the GST portal — sales & purchase registers, GSTR-1 / 2B / 3B reconciliation, IMS and e-invoicing, all in one place and reconciled before you file.
GST prep still lives in a dozen spreadsheets
Return software files what you already organised. Accounting software needs the client to run it. The layer in between — where the actual monthly GST work happens — has only ever been Excel.
A file per client, none of them tie out
Separate sheets for sales, purchase and 2B reconciliation — copied forward each month and never quite matching the portal.
Re-keying the portal by hand
Downloading GSTR-2B, 1 and 3B and pasting figures into spreadsheets, month after month, GSTIN after GSTIN.
ITC mismatches found too late
Gaps between your books and GSTR-2B surface after filing — when reversing or claiming is far harder.
One reconciled workspace for every GSTIN
GST Working File productises that in-between layer. Record outward and inward supplies, pull the real figures straight from the GST portal, let the app match them to your books and flag every gap — then produce filing-ready outputs and e-invoices. Built for a practising CA’s monthly workflow across many clients, and just as clean for a single business.
Everything the monthly GST file needs
Sales & Purchase registers
Item-level entry with HSN, tax split and return-period tagging. Type it, paste from Excel, or extract straight from invoice PDFs.
GSTR-1 — Books, Portal & Reco
Build GSTR-1 from your sales, fetch the filed return, and reconcile the two — monthly or annual, with amendments captured.
GSTR-2B & IMS
Pull 2B and the Invoice Management System from the portal, accept or reject invoices, and match ITC to your purchase register.
GSTR-3B — Books vs Portal
Assemble 3B from your data, capture the filed summary, and reconcile liability and ITC side by side before you pay.
One-click portal fetch
The GST Working File Connector pulls GSTR-1, 2B, 3B and IMS directly from the portal — you solve the captcha, it does the rest.
e-Invoicing, two ways
Generate IRNs, or download a portal-ready bulk JSON for B2B / SEZ / export — validated against the schema, no API needed.
Reconciliation that flags gaps
Sales vs GSTR-1, Purchase vs 2B, 3B Books vs Portal — every mismatch surfaced before filing, not after.
Reports & compliance tracker
Year-to-date outputs, Excel exports and a due-date tracker — plus a CA console for every client with read-only client logins.
Your data, access-controlled
Role-based team access, per-company scoping and client logins that see only their own company. Nothing shared by default.
From entry to filing-ready in six steps
Add your companies
Set up your company — or every client GSTIN — once, with registration type and e-invoicing details.
Enter or import supplies
Key sales & purchases, paste from Excel, or extract them from PDFs — tagged to the right return period.
Pull from the portal
Fetch GSTR-1, 2B, 3B and IMS with the connector — the live figures, not a manual download.
Reconcile automatically
The app matches your books to the portal and flags every mismatch — invoice by invoice.
Act on ITC
Accept or reject in IMS and close the 2B gaps, so you claim the right credit before you file.
Produce outputs
Filing-ready summaries, e-invoice JSON and review reports — ready to file and ready to hand to the client.
