Quatuor TMS’s AEAT modules automatically generate the accounting entries and electronic files required by the Tax Agency for products subject to Excise Duties (primarily hydrocarbons). The system applies the specific accounting logic for each type of operation (release for consumption, export, return, regulatory loss, etc.) and generates the accounting record books that must be submitted to SILICIE. This eliminates the need for double data entry and drastically reduces the risk of errors or tax penalties.

SILICIE (Sistema Informático de Libros de Contabilidad de Impuestos Especiales) is the AEAT’s electronic platform where energy sector companies must declare all movements of products subject to Excise Duties in real-time. Quatuor’s TMS is specifically developed to automatically generate the XML messages required by SILICIE in the correct format and timeframe, connecting directly with the Tax Agency without manual intervention from the operator. This guarantees continuous regulatory compliance without burdening your team with additional administrative work.

Yes. Quatuor’s TMS features bidirectional integration connectors with the market’s leading ERP systems: SAP, Oracle, Microsoft Dynamics, Sage, and others. The integration is configured to synchronize relevant data in each case: purchase/sales orders, billing, client/vendor data, and general ledger accounting. In this way, the TMS acts as the terminal’s operational system while the corporate ERP maintains the global financial view, avoiding duplicate data entry.

TMS onPremise is installed and executed on the terminal’s or corporate group’s own servers. This offers several advantages in the petrochemical sector: maximum security by not relying on an internet connection for critical operations, total control over data and its location (GDPR compliance in industrial environments), guaranteed availability even during connectivity outages, and total adaptability to corporate IT security policies. It is the preferred option for large energy groups and critical infrastructures. For smaller operators or those with multiple dispersed terminals, we also offer managed hosting modalities.

Quatuor Tank Monitor is supervisory software that connects to field instruments installed on your tanks (level gauges, thermometers, density meters, leak detectors) via standard industrial protocols (Modbus, OPC-UA, etc.). Data is received in real-time and displayed on a web dashboard accessible from any device. The system allows you to configure threshold alerts (minimum/maximum level, abnormal temperature), generate automatic inventory reports, and export data to higher-level management systems. Its implementation is non-intrusive and compatible with existing SCADA systems.

The implementation time depends on the size and complexity of the terminal, but our typical projects are executed within a 3 to 6-month timeframe. This period includes the analysis of current processes, system parameterization to your specific needs, integration with existing systems (ERP, SCADA, weighbridge), historical data migration, team training, and assisted production go-live. Our methodology is designed to minimize operational disruption: the new system is launched in parallel with the previous one, and the handover is carried out gradually and securely.

Quatuor’s TMS is developed with full knowledge and compliance of the Spanish and European regulations applicable to the petrochemical sector: Excise Duties Law and its implementing regulations, AEAT SILICIE obligations, ADR regulations for the transport of dangerous goods, requirements for Tax Warehouses and Fiscal Warehouses, legal metrology regulations applicable to meters and measuring systems, and environmental regulations regarding emissions and spills. Quatuor’s development team continuously monitors regulatory changes to incorporate them into software updates, guaranteeing permanent compliance at no extra cost to the client.

Yes. Our technical support team consists of professionals with combined knowledge of software and the petrochemical business. This means that when an incident is reported, the responding technician understands not only the IT aspect but also the operational context: what operation was being performed, what the impact on the process is, and what the most appropriate solution should be. We offer different SLA (Service Level Agreement) levels tailored to each client’s needs, from standard business hours support to 24/7 assistance for terminals with continuous operations.

Quatuor’s TMS is designed with a parameterizable architecture that allows adapting the vast majority of the system’s behaviors without the need for custom development: types of operations, approval workflows, document formats, accounting rules, integration interfaces, and dashboards are configured via parameters. Custom development is only used for truly unique functionalities of your terminal or corporate group, and it is built upon the stable foundation of the standard product. This reduces cost and implementation time, and guarantees that your system can be seamlessly updated in the future.
