Designed for the teams carrying European invoice risk
Taxexa secures $470K in funding from GAMA.
Taxexa is funded by GAMA as it builds tax compliance for complex operating environments.
Tax compliance shouldn't live across spreadsheets, emails and disconnected documents.
Manual VAT validation, changing regulations and scattered supporting evidence slow finance teams and increase compliance risk.
Cross-border VAT
Different countries require different VAT treatments, creating uncertainty during every transaction.
E-Invoicing
Invoices move through multiple systems before becoming compliant.
Missing Evidence
Receipts, contracts and supporting documents become disconnected from the original transaction.
Determine. Check. Prove.
Taxexa connects transaction facts, applicable rules, invoice checks and supporting evidence into one reviewable decision trace.
Follow the decision from transaction facts to audit-ready context.
A single fictional Poland-to-Germany invoice connects Taxexa Rules, Check and Evidence into one continuous review path.

Three products. One defensible decision.
A modular concept spanning rule determination, invoice validation and the evidence needed to support the conclusion.
Taxexa Rules
Identify the VAT treatment, authority source and effective rule behind each scenario.
Taxexa Check
Validate VAT IDs, invoice fields and transaction facts before the invoice moves.
Taxexa Evidence
Connect every conclusion to the documents, timestamps and reviews that support it.
Not just a green check. The reasoning behind it.
An illustrative view of how Taxexa could expose inputs, applied rules, validation results, missing evidence and the next review action.
- Seller
- PL · VAT registered
- Customer
- DE · Valid VAT ID
- Supply

Built around the direction of European invoicing.
This demo explores how a single control layer could connect today's Polish KSeF operations with the longer-term direction of ViDA—without pretending every country follows one identical workflow.

KSeF operating reality
A live Polish e-invoicing environment with phased obligations, rejection handling and offline procedures.

EU digital reporting
Structured e-invoicing supports digital reporting for affected intra-EU B2B transactions.
Credibility without pretending the concept is live.
Taxexa is presented as an interactive startup concept. The interface demonstrates how explainable VAT operations could work; it does not claim customers, certifications, live integrations or production coverage.
Sources stay visible
Every illustrated rule result includes its authority reference and jurisdiction.
Dates matter
Effective dates and review dates appear beside the fictional decision.
Uncertainty is explicit
Missing inputs and unavailable sources become review states—not silent assumptions.
Humans remain accountable
The concept keeps reviewer actions and approvals visible in the decision history.
Illustrative plans for different operating models.
Demo pricing shows one possible packaging model and is not a commercial offer.
