For 40–90 person Indian companies: we reconstruct your complete recurring vendor spend from your accounting ledger, compute the reverse-charge GST (RCM) exposure and Input Tax Credit position on the foreign-billed ones, and extract contract notice deadlines. Delivered in 7–10 working days as an audit-ready register your CA can file against.
| Narration | Entity | RCM | Self-inv. |
|---|---|---|---|
| FIGMA*SANFRANCISCO | Figma Inc (US) | Yes | Overdue |
| AMAZON WEB SERVICES | AWS India Pvt Ltd | No | n/a |
| MSFT SUBSCRIPTION | Microsoft (SG) Web Direct | Yes | Overdue |
| GOOGLE*CLOUD_ASI | Unidentified | — | Exception queue |
Every row carries a Basis & assumption note and an explicit “could not confirm” list. Illustrative sample.
100% independent. We take ₹0 in vendor kickbacks, reseller margins or referral commissions — stated in our engagement letter.
Why this exists
Your CA files what arrives on their desk. Your accounting software computes the maths once a bill is entered. But when international SaaS is billed across team cards and employee reimbursements, charges hit the ledger as vague bank lines without vendor identity or tax treatment. Nobody owns the complete, de-aliased population — that is the gap we close.
Foreign-billed software (Figma, Notion, Microsoft Web Direct, dev tools) attracts reverse-charge IGST under s.5(3) IGST Act. The foreign vendor cannot issue an Indian GST invoice, so your company must raise a self-invoice within 30 days (Rule 47A).
If undeclared, you owe the tax in cash plus interest under s.50. RCM cannot be discharged from accumulated ITC.
Indian entities of global tools or domestic vendors frequently invoice without your GSTIN on file. Under s.16(4), unclaimed ITC lapses on the earlier of 30 November following the financial year or the annual-return date.
Every un-reissued invoice and un-raised self-invoice is real business cash permanently forfeited.
Industry analysis of standardised cloud agreements finds most auto-renew, and a large share require a 30-day non-renewal notice. Many include automatic fee increases.
Seats paid for departed staff, duplicated tools, and annual contracts that renew because nobody tracked the notice window.
Tax logic & vendor routing
Your tax liability depends on which legal entity contracts and invoices, not the vendor’s brand name — and not simply whether your GSTIN is on file. The same brand can be domestic on one product line and cross-border on another.
| Vendor / tool | Contracting & invoicing entity | Billing currency | GST treatment | RCM? |
|---|---|---|---|---|
| AWS | Amazon Web Services India Pvt Ltd | INR | Domestic forward charge (18% GST) | No — direct ITC |
| Google Cloud | Google Cloud India Pvt Ltd | INR | Domestic forward charge (18% GST regardless of GSTIN status) | No — direct ITC |
| Meta Ads | Facebook India Online Services Pvt Ltd | INR | Domestic forward charge + TDS | No — direct ITC |
| Microsoft Azure / M365 | Microsoft Regional Sales Pte Ltd (Singapore) — Web Direct | Cross-border | Import of service / RCM applies | Yes — self-invoice mandatory |
| Microsoft Azure / M365 | Microsoft Corporation India Pvt Ltd — Customer Agreement | INR | Domestic forward charge | No — direct ITC |
| Figma / Notion / GitHub | US / overseas operating entities | USD / FCY | Import of service / OIDAR | Yes — self-invoice mandatory |
Note: Vendors absent from our reference table default to “foreign-billed / RCM-eligible — evidence required.” The invoice is always the deciding evidence. Routes change per product line and contract vehicle, so we maintain the table at vendor × product × contract-vehicle granularity.
No software adoption required
In 7–10 working days your finance team and CA receive a complete, verifiable deliverable pack. No logins to maintain, no dashboards to check, no integrations to adopt.
One unified view: vendor, owner, card/account, currency, domestic vs. foreign entity, GSTIN status, RCM liability and self-invoice status.
Sourced Basis & assumption column on every tax row, with statutory citations.
Exactly when self-invoices must be raised to satisfy Rule 47A, upcoming contract cancellation notice windows, and s.16(4) ITC cut-offs.
Every deadline carries a named owner.
Pre-formatted GSTIN-reissue requests to domestic vendors, and contract cancellation or downgrade notices with clause citations.
You review and send. We never send on your behalf.
Forward rules for future purchases: who may buy, which card, mandatory GSTIN inclusion, and remittance steps.
A named, delivered artifact — not general advice.
Built for your Chartered Accountant: the register subset, GSTR-3B Table 3.1(d) breakdown, Rule 56(1) record-keeping, and the direct-tax/remittance line.
The only place the direct-tax exposure line appears — never on your board pack.
Showing what we could not confirm — with a stated reason — is what makes the rest of the register credible.
Radical transparency
No single component of the offer clears the fee alone against a free alternative. Defensibility rests on assembling all three components — plus written independence — into one CA-accepted, evidenced deliverable.
Zero friction & DPDP-ready
Supply standard ledger/trial-balance exports (Tally, Zoho Books, Busy, Marg), company-card statements, reimbursement claims and signed SaaS order forms.
We never ask for bank logins, employee personal-card statements, or OAuth access.
Vision models parse unstructured billing lines against our Indian-billing reference table. Every computation is deterministic — not LLM guesswork — and a human specialist reviews all tax rows.
Low-confidence fields become human questions, never guesses.
Receive the five deliverables with per-row Basis notes and an explicit could-not-confirm list. Your CA reviews the GSTR-3B RCM numbers and files; you send the drafted emails.
We never file returns, give legal opinions, or cancel on your behalf.
Encryption in transit and at rest; per-engagement isolation.
DPDP-aligned itemised consent; purpose limitation enforced.
Deletion on request, with a written deletion date on the consent.
End to end
No app, no login, no integration. The product experience is a delivery experience — built around trust at every step.
A 15-minute call checks fit: 40–90 people, ≥30 recurring vendors, meaningful foreign-billed spend, no procurement function, and a live trigger.
See the redacted sample register, or run a free exposure screen — counts and ranges only, no per-row amounts.
Tier and flat fee stated, the guarantee explained, and the actionable-window scope disclosed in plain terms.
Engagement letter and DPDP consent signed; 100% advance via a payment link. No work starts before payment.
A dedicated intake address and per-engagement folder. You supply the ledger export, reimbursement claims, and company-card statements.
Vision extraction → human exception queue → deterministic rules engine. Four-eyes review on every tax column.
A partial truth within days — vendor counts, foreign share, missing self-invoices — before the full pack lands.
Five artefacts plus the CA hand-off sheet. Your CA files; you send the drafted emails. We never file or send.
Optional Forward Register (₹2,500/month) keeps the matrix current by invoice forwarding, with notice-window alerts.
Quick estimate
Move the slider to your approximate monthly software spend. This is an illustrative estimate using disclosed assumptions — not a computed tax position.
RCM principal generally nets or refunds to roughly zero; the real exposure is interest on delay and time-barred credit. Assumptions: 40% foreign-billed, 18% GST, 1.5% illustrative ITC opportunity. Not tax advice. Your actual position is computed from your documents.

Easier GSTR-9 / 9C reconciliations

Answers
Accounting systems compute RCM only after someone identifies the vendor, determines taxability, and types the bill in. They cannot look into your general ledger, de-alias an ambiguous bank line (FIGMA*SANFRANCISCO), decide whether a Microsoft Web Direct charge is billed from Singapore or India, or extract cancellation clauses from signed PDFs. We do the discovery work upstream and feed them clean data.
Under s.31(3)(f) CGST, a registered recipient must issue an invoice to itself for reverse-charge supplies from an unregistered supplier. Under Rule 36(1)(b), this self-invoice is the document required to claim Input Tax Credit. Effective 1 November 2024 (Rule 47A), the self-invoice must be issued within 30 days of receiving the supply.
Never. No bank APIs, screen scrapers, or OAuth tokens. You provide standard Excel/CSV/PDF exports of your ledger and company-card statements.
We intake ledger files and company cards, and we strictly refuse founders' and employees' personal card statements — so personal data entry is minimised by design. Files are held in isolated, access-controlled environments, used only for the engagement, and deleted on the schedule stated on your consent (with a written deletion date).
CAs value Ventrix because we do the forensic ledger work their teams dislike and cannot easily bill for. We deliver a ready-to-file schedule that supports Rule 56(1) CGST record-keeping and strengthens their client's position. We never file returns, offer legal opinions, or position ourselves as an audit of the CA.
