Meet the tax department behind your tax department

Transactional compliance is the end-to-end process of staying compliant, starting at the moment a transaction happens — from getting tax right on the invoice and meeting real-time e-invoicing/CTC requirements to reconciling what was transacted with what must be reported and filed. With Thomson Reuters, that means connecting tax determination, e-invoicing, reconciliations, and compliance/filing so your team can move from reactive, last-minute work to a more automated “transaction to filing” workflow.

We provide a single, end-to-end workflow that spans the invoice-to-filing journey — linking ONESOURCE Determination (tax calculation) with ONESOURCE Pagero (e-invoicing life cycle), ONESOURCE Reconciliations, and ONESOURCE compliance/filing capabilities. This unified approach is designed to reduce integration complexity by delivering one connected platform experience across the transactional compliance life cycle. The result is greater consistency and auditability from the moment tax is calculated through e-invoice exchange/validation and into filing-ready reporting.

Our approach combines global tax content depth with e-invoicing compliance coverage so you can operate confidently across jurisdictions. ONESOURCE provides global tax rates/rules coverage across 205 countries and territories, supporting accurate determination wherever you do business. For e-invoicing, ONESOURCE Pagero delivers compliance through an open global network with coverage cited as over 75 countries in our enablement materials — supporting evolving mandates and digital reporting requirements. Together, this helps enterprises standardize compliance operations globally while still meeting local requirements.

ONESOURCE Pagero is built on one open, global network that connects businesses with customers, suppliers, and government platforms — so you can exchange and comply with e-invoices through a single connection rather than stitching together country-by-country point solutions. This network model supports the full e-invoicing life cycle — formatting, validation, delivery, real-time status/acknowledgments, and traceability — helping improve control and visibility across invoice flows. It also enables universal connectivity with options such as pre-built connectors — for example, SAP and Oracle — and a global API, helping organizations scale multicountry rollouts with less technical overhead.

ONESOURCE is built to deliver enterprise-grade reliability and operational ease for always-on compliance — using cloud-native capabilities like autoscaling and self-healing while minimizing disruption with no-downtime updates. Customers also benefit from enterprise security and controls — including references to ISO-aligned standards and SLA/uptime commitments in our materials — plus centralized dashboards and workflow visibility to support oversight and audit readiness. In short, you get a platform designed to handle change continuously — across mandates, rules, and volumes — without forcing your team to manage constant upgrades and rework.
