Alejandro Aumedes Terés, tax ID (NIF) 43745658A, as the producer of the invoicing system described below, makes this declaración responsable (declaration of conformity) under Article 13 of the Regulation approved by Royal Decree 1007/2023 of 5 December, and Article 15 of Order HAC/1177/2024 of 17 October.
The invoicing system
- Name: Ops
- Identification code: OP
- Version: 0.3.0
Components and functions
Ops is a web application for project management and invoicing, provided as a service. Each customer has its own instance: its own application server and its own PostgreSQL database, hosted on servers in the European Union. It is used from a web browser.
The system has two components:
- The Ops application, made by the declarant. Users prepare invoices as drafts and issue them. When an invoice is issued, Ops gives it a final number, consecutive and without gaps within the series of each issuing NIF. From then on the invoice is locked: it cannot be edited or deleted, only cancelled or corrected with a corrective invoice. Ops classifies each transaction for VAT and produces the invoice PDF with the QR code and the "VERI*FACTU" legend.
- The billing-record module of BOLD Software, connected to Ops through its API. It generates the registration and cancellation billing records, chains them with their hash (huella) and sends them to the Spanish Tax Agency (AEAT). This component has its own declaration of conformity, made by its producer.
This declaration covers the Ops application and its integration with BOLD Software's module.
Operating mode
- Used only as a VERI*FACTU system: yes. Every billing record is sent to the AEAT. If it cannot be sent when the invoice is issued, the record is queued and sent again automatically.
- Used by several taxpayers: yes. One instance can issue invoices for several NIFs, each with its own numbering series.
- Signature of the records: not applicable. In VERI*FACTU mode the records are sent to the AEAT as they are generated, and the rules do not require them to be signed electronically.
