India GST · EU VAT · Design-partner programme open
Know the tax treatment before the invoice posts — and why.
Aurevat determines India GST and EU VAT line by line, cites the provision behind each answer and keeps the evidence. It is new software from an old hand at indirect tax, and we have no customer logos to show you yet — only an engine you can test against your own data today.
- 19 years
- Indirect tax implementation experience behind the engine — Vertex O Series and SAP FICO
- 27 EU + India
- Member state VAT rulesets plus India GST, with place-of-supply and reverse-charge logic
- 0 customers
- We are pre-revenue. Early partners are priced and treated accordingly
What the platform does
Four things, done properly
Nothing here is a projection. This is the behaviour available to a design partner today.
Determination, not a rate lookup
Place of supply, liable party, registration status, reverse charge and rate resolved together for each line — the sequence a tax reviewer would follow.
Validation of what your ERP already produced
Import a transaction export and Aurevat re-determines each line, then flags only where its answer differs from yours, with the difference stated plainly.
A citation on every answer
Each determination carries the statute or directive article it rests on, so a reviewer can agree or disagree with the reasoning rather than the output.
An evidence trail that survives an audit
Inputs, rule version, result, reviewer and any override are recorded immutably. You can reconstruct why a line was treated that way months later.
ERP connectors
Works with the systems you already use
Aurevat reads a transaction export from your ERP, maps its column names, re-determines every line server-side and never writes anything back. The mapping profiles below are live today — bring a month of your own data and compare.
India
- Available today
Tally Prime
Tally Solutions
Display More Reports > Account Books > Sales Register, then Export in CSV (Detailed) format.
Place of supply in the Tally register drives the intra vs inter-state split automatically.

Zoho Books
Zoho
Sales > Invoices > Export Invoices (CSV), with GST fields included.
A scheduled Zoho Books API pull is in build — it needs a sandbox organisation before it can be verified.
Global
- Available today
SAP S/4HANA
SAP
Billing document list (VF05N) or FI line items (FBL5N) exported to spreadsheet, saved as CSV.
Mapping matches a standard VF05N layout. Field names differ per client configuration, so review the first run.
- Available today

Receivables > Billing > Manage Transactions, export the transaction lines to CSV (or an OTBI transaction line extract).

Stated plainly
What we can prove, what we're building, what we can't claim
Most software in this category leads with percentages it cannot show you the working for. Here is the whole picture instead, including the parts that don't flatter us.
19 years implementing indirect tax for global enterprises of indirect tax implementation experience
Vertex O Series and SAP FICO tax configuration across enterprise rollouts. Verifiable — ask and we will walk you through the engagements.
India GST and EU-27 VAT determination logic
CGST/SGST/IGST and all 27 EU member state standard rates, with place-of-supply and reverse-charge handling. Rate data current as of 1 January 2026.
Rule citation and audit trail on every determination
Built into the engine, not a reporting add-on. Try it on the public demo.
ERP connectors for SAP S/4HANA, Oracle Fusion, Dynamics 365, NetSuite, Tally Prime and Zoho Books
Export-based today and read-only: Aurevat maps the column names, recomputes every line server-side and never writes back into the ERP. First runs are reviewed together.
Scheduled ERP API pulls (Zoho Books first)
In build. A sandbox organisation is needed before it can be verified — we will not claim a live integration before then.
Statutory report formats (SAF-T, Peppol, SDI, SII)
In build. We will name the exact formats and versions when each one is tested, not before.
Live filing submission to tax authorities
Not built. Aurevat prepares and evidences; you or your filing agent submit.
Customer case studies and named references
We have none, because we have no customers yet. There is no logo strip on this site for that reason. The first pilots will be named only with written permission.
SOC 2 / ISO 27001 certification
Not held. Our security posture is described in plain terms on the security page instead of behind a badge.

How a pilot runs
Three steps, no implementation project
A pilot is deliberately small. If the engine doesn't earn its place on your own data, there is nothing to discuss.
- 01
Send a representative export
A CSV or XLSX of transaction lines from your ERP — a month is usually enough. No connector, no IT ticket, no sandbox.
- 02
Aurevat re-determines every line
Place of supply, liable party, rate and rule reference, computed independently of what your system decided.
- 03
We review the differences together
You get the flagged lines with the reasoning beside each one. Some will be our engine learning your policy; some will be findings you can act on.
Who is behind it
Dr. Harish Ojha
Founder, Pinnacle Consultancy Group
“I spent nineteen years configuring determination logic inside other people's tax engines and watching finance teams inherit answers they could not explain. Aurevat exists to show the reasoning, not just the rate. Until a customer says that worked, I would rather publish what the software actually does than a number I cannot evidence.”

If the engine disagrees with your ERP, you will see exactly where and on what authority. That conversation is useful whether or not you ever become a customer.
