GST Compliance
GST that files itself.
GSTR-2B reconciled overnight. GSTR-1, 3B, 9 and 9C drafted from your books. ITC eligibility per invoice, place-of-supply at every line, multi-state and multi-country.
GSTR-2B Reconciliation
GSTR-2B reconciled overnight.
Authorised GSP pulls 2B for every GSTIN at 02:00 IST. Three-way match against your purchase register and books on PAN, GSTIN, invoice number, date and tax components. Vendor non-filers, near-matches, missing-in-2B and amended-by-supplier each surface in their own bucket with a resolution path.
GSTR-1 Filing
GSTR-1 drafted from your invoices.
B2B, B2C (large), B2C (small), exports, SEZ, deemed exports, credit and debit notes, advances and amendments. All sections of GSTR-1 auto-populated from your invoice book. CA reviews, signs off with DSC, files via authorised GSP API. The GSTN response posts back automatically.
GSTR-3B Filing
GSTR-3B drafted from your books, gated by 2B sign-off.
Outward supplies, ITC available, ITC reversed (Rule 42/43), RCM liability and net tax payable all drafted from the books. Table 4 auto-populated against the GSTR-2B match. Filing only happens after the period is signed off.
GSTR-9 Annual Return
GSTR-9 drafted. Variances flagged.
Annual return drafted from twelve months of filed GSTR-1, GSTR-3B and books. ITC reconciliation surfaces variances at the line level. Demand and refund tracking inline. CA reviewer signs off with DSC. Filing pushed via authorised GSP.
GSTR-9C Reconciliation
GSTR-9C drafted from books. CA signs off with DSC.
Reconciliation between annual financial statements and the GSTR-9 return, drafted automatically. Variances at the line level. Tax-audit alignment under Section 44AB read with Section 35(5). Multi-tenant CA-firm portal supports review across clients.
ITC Management
ITC tagged at the bill.
Every bill line gets an ITC eligibility tag (eligible, ineligible, RCM, blocked) at capture. Section 17(5) blocked credits identified automatically. Rule 42/43 common-credit reversal computed on actual turnover. ITC at risk surfaced before payment. Section 16 conditions enforced.
GST Compliance Calendar
Every filing, mapped to entity, state and owner.
GSTR-1, IFF, 3B, 9, 9C, ITC-04 and CMP-08 tracked per entity, per state, per GSTIN. Owner per filing. Slack and email reminders. Evidence packs auto-assembled per filing for the next audit. Multi-country (India, UAE, UK, Singapore) on the same calendar.
Place of Supply Rules
Place of supply, validated at invoice creation.
Sections 10, 11 and 12 of the IGST Act applied at invoice creation. Branch transfer vs interstate sale auto-classified. Service-specific rules (telecom, banking, training, transportation) handled. The wrong CGST/SGST vs IGST split never makes it to the books.
RCM Compliance
Reverse charge handled at capture.
Notified categories under Section 9(3) (legal, GTA, security, advocate, residential rent, import of services) auto-flagged. Section 9(4) flagged where applicable. Self-invoice with IRN where the threshold applies. GSTR-3B Table 3.1(d) populated. ITC claimed the next month per Section 16(2)(c).
GST Audit Evidence Pack
Per-return evidence pack, hash-verified, audit-ready.
Every filed return ships with its evidence: source invoices, the 2B match, the Rule 42/43 reversal workpaper, the CA sign-off, the DSC trail, the GSTN ARN. Packaged hash-verified per period. Department audit, scrutiny notice and statutory audit all answered from one pack.
GSTN Portal Integration
Every GSTN action from inside OneFinOps.
IRN generation, e-way bill, GSTR filing, 2B pull, IMS actions, refund applications and demand notice responses. All via the authorised GSP API. No portal switching. Status posts back automatically.

Buyer FAQ
What teams ask before they switch.
Will the system actually help us recover ITC we are missing today?
Most teams see the equivalent of 15 to 20% of monthly ITC in the first 90 days, almost entirely from catching vendor non-filers and amount mismatches before GSTR-3B is pushed. The recon engine flags ITC at risk at the bill, so the AP team can chase the vendor or hold the payment before the ITC window closes.
We have GSTINs in 6 states. Does it consolidate?
Yes. Per-GSTIN filings run in parallel with an entity-level rollup. Multi-state branch transfers are handled with the right place of supply. The CFO sees ITC, output liability and filing status across all GSTINs on a single dashboard.
GSTR-9C requires CA sign-off. How does that work?
GSTR-9C is drafted from the books with the variances against GSTR-9 surfaced for review. CA reviewer access is provisioned per FY. Sign-off is captured with DSC, and the supporting workpaper is hash-verified for audit. CA-firm portal supports multi-tenant review.
Reverse charge (RCM). How is it handled?
RCM bills are tagged at capture under Section 9(3) (notified categories) or 9(4) (registered buyer, unregistered seller). Self-invoice raised with IRN where applicable. The liability flows to GSTR-3B Table 3.1(d), with the matching ITC claim drafted for the next month per Section 16(2)(c).
How does it handle place-of-supply mistakes that cost us ITC?
The place-of-supply rules engine validates at invoice creation. Branch transfer vs interstate sale auto-classified per Sections 10, 11 and 12 of the IGST Act. Mistakes flagged before posting, so the wrong CGST/SGST vs IGST split never makes it to the books.
IMS (Invoice Management System). Can we use it from here?
Yes. IMS-actioned invoices (accepted, rejected, pending) are read alongside GSTR-2B. Full IMS workflow runs from inside the recon screen, so your books, your IMS state and your 2B stay aligned.
We file GST in India and VAT in UAE. Can the same platform handle both?
Yes. Multi-country tax is native. Indian GST, UAE VAT, UK MTD VAT, Singapore GST and EU VAT/OSS run on the same platform with the right rule set per jurisdiction. Group consolidation rolls up across countries.
