How the DGT's position has evolved
Current position
The billing computer system is the set of hardware and software that accepts, preserves, and processes billing information while complying with the requirements of integrity, traceability, and inalterability of the RSIF. The automatic submission of records is voluntary, although its adoption allows for the use of VERI*FACTU systems. Operations exempt from issuing invoices according to the ROF are excluded from the objective scope of the RSIF.
The DGT's position has shifted from focusing on the mandatory nature of the SII and submission deadlines to technically defining billing computer systems under the new RSIF framework. The nature of devices (cash registers, card terminals) and the distinction between the obligation to issue invoices and the obligation to comply with the technical requirements of the regulation have been clarified.
Turning points
-
Defines cash registers as billing systems as long as they comply with requirements of integrity, preservation, accessibility, legibility, traceability, and inalterability.
-
Clarifies that if an operation is exempt from issuing an invoice according to the ROF, it does not need to comply with the technical requirements of the RSIF.
