Platform Modules

Eight integrated modules. One connected system.

SYNE One is not a bundle of loosely connected apps. Every module shares the same data layer - so actions in one area automatically propagate across every other, eliminating reconciliation and double-entry forever.

Tax Management

Cross-border tax. Automated at source.

For businesses operating across multiple jurisdictions, tax compliance is one of the most expensive and error-prone parts of finance operations. SYNE One embeds tax calculation, validation, and reporting directly into every transaction - so the right treatment is applied automatically at the point the invoice is created, not discovered at year-end.

85+ countries. Real-time calculation. Zero retroactive corrections.
Tax rates and rules update automatically as legislation changes - your team never manually manages a rate table again.
🌐

Multi-Jurisdiction VAT & GST

Tax rates, rules, and exemptions applied automatically based on transaction type, supplier location, and buyer location across 85+ countries - with exports to MTD, ELSTER, IRAS, and iTax filing formats.

🌍

CBAM Embedded Carbon Tax

For EU importers, embedded carbon cost is calculated against current CBAM rates using verified traceability data - not sector estimates. Quarterly CBAM declarations pre-populated and registry-ready.

📋

Transfer Pricing Documentation

Inter-entity transactions automatically apply your configured transfer pricing policy and generate contemporaneous documentation - reducing audit risk and compressing compliance from weeks to hours.

🔒

Withholding Tax & Reverse Charge

Withholding obligations on supplier payments and reverse charge VAT on cross-border services are identified and applied at invoice level - with statutory reports pre-populated automatically.
