Built for change with standardized data, automated validations, and rapid sync that reduce friction from day one.
Global e-invoicing mandates are reshaping compliance for businesses worldwide. More than 90 countries now require real-time invoice reporting and continuous transaction controls (CTCs), putting tax teams under pressure to maintain accuracy, speed, and transparency in every transaction. Outdated processes and disconnected technology simply can’t keep up.
ONESOURCE Pagero and Oracle have partnered to deliver an embedded e-invoicing solution that simplifies compliance and scales globally. In this blog, we’ll cover how the integration works, its technical foundation, and practical steps to future-proof your organization.

Key benefits of embedded e-invoicing
By embedding e-invoicing directly into Oracle Fusion ERP, businesses gain a unified solution that minimizes change management and grows with their needs.
Three major advantages for global enterprises:
- Real-time compliance across 85+ countries: ONESOURCE Pagero’s global network integrates natively with Oracle, validating invoices instantly and reducing compliance risk without manual intervention.
- Lower IT complexity and cost: Embedded capabilities eliminate third-party middleware and custom connectors, freeing up IT resources for strategic projects.
- Faster onboarding and global rollout: Pre-configured mappings enable quick activation across jurisdictions, minimizing errors and accelerating expansion.
For tax leaders, this translates to fewer compliance headaches, lower costs, and greater confidence in meeting global mandates.
The technical foundation: CMK framework and PUF mapping
The integration relies on two critical components: Oracle’s Collaboration Messaging Framework (CMK) and ONESOURCE Pagero’s Universal Format (PUF).
Oracle’s CMK framework
CMK is Oracle’s standard for exchanging structured messages between ERP systems and external platforms. It supports outbound invoice messages for accounts payable (AP) and accounts receivable (AR) processes and captures inbound responses from tax authorities or suppliers.
However, CMK has limitations when handling complex mandates. For example, it does not validate response codes for AR flows, requires additional BI Publisher integrations for cross-border AP scenarios, and often needs custom lookup tables for mapping non-standard fields.
ONESOURCE Pagero’s Universal Format (PUF)
PUF standardizes invoice data across multiple jurisdictions, ensuring consistency and compliance. It supports country-specific requirements, real-time embedded validations for mandates like ZATCA in Saudi Arabia or KSeF in Poland, and scalability for future changes. Together, CMK and PUF create a robust foundation for global e-invoicing.
How Oracle CMK maps to Pagero PUF for seamless compliance
Mapping Oracle’s CMK message structure to Pagero’s PUF schema is the key to achieving compliance without manual intervention.
Here’s how it works:
- Field alignment: Standard Oracle invoice fields, such as supplier details and tax amounts, are mapped to PUF equivalents.
- Custom extensions: For countries with unique regulatory demands (e.g., Malaysia’s self-billing, Italy’s split payment), custom attributes are added to CMK messages and mapped to PUF.
- Dynamic lookups: Lookup tables ensure accurate mapping of tax codes and payment terms.
- Real-time synchronization: ONESOURCE Pagero uses webhook notifications to trigger updates in Oracle every few minutes, ensuring invoice statuses remain current.
This mapping strategy ensures that invoices generated in Oracle are automatically validated, enriched, and reported according to each country’s requirements.
Why embedded e-invoicing is the future for global enterprises
ONESOURCE Pagero’s embedded integration with Oracle Fusion ERP is designed for organizations that operate across multiple jurisdictions and need a unified compliance strategy.
Scalability and automation are key advantages
Pre-mapped fields and native integration make it easy to add new entities or adapt to changing regulations without heavy customization. Touchless AP and AR processes, powered by webhook notifications and AI-driven validations, reduce manual intervention and minimize errors.
For organizations prioritizing real-time compliance, the embedded connector ensures continuous transaction controls and real-time reporting without disrupting existing workflows.
If you’re already running Oracle Fusion or planning a migration, this embedded approach eliminates the need for custom connectors and multiple country-specific solutions. Instead, you gain a single compliance layer that integrates seamlessly into your ERP environment, reducing IT complexity and accelerating time-to-value.
Assess your current needs before implementation
Implementing embedded e-invoicing can transform compliance and operational efficiency, but success depends on planning. When done well, it reduces risk and supports broader finance transformation objectives.
Evaluate your current state
Use the Pagero compliance map to identify where e-invoicing mandates apply and understand the requirements in those jurisdictions. Then, review your ERP setup to uncover any gaps or manual processes that could slow down compliance. This helps prioritize countries needing immediate action.
Engage key stakeholders early
E-invoicing compliance isn’t an isolated project—it affects tax, finance, AP, AR, IT, procurement, and operations. Align these teams on timelines, technical needs, and goals to ensure smooth implementation. This collaboration ensures decisions support both business workflows and regulatory obligations.
Verify technical readiness
Before you can automate invoice flows, make sure your master data is in good shape. Confirm that key information—such as supplier details, tax codes, and country-specific attributes—is accurate and centralized in your ERP system. Clean, consistent data is essential for automation and scaling.
Test before go-live
Use Oracle’s UAT pods to validate invoice flows and simulate real-world AP and AR scenarios, including exceptions. After go-live, focus on maintaining compliance by monitoring invoice statuses and error logs in Oracle and using Pagero’s analytics to track performance across jurisdictions. This proactive approach helps you stay ahead of evolving mandates—even in markets without current requirements.
Consider a phased rollout
If you’re rolling out gradually, start with countries that have strict real-time clearance requirements, such as Saudi Arabia or Italy, to reduce compliance risk quickly and demonstrate early success.
