In Uruguay, certification applies to the software used to issue e-Receipts and other electronic fiscal documents, not to the POS application itself. Before production use, the software must pass testing and homologation with the Tax Authority to prove that it can generate XML documents, apply digital signatures, communicate with the TA, process responses, and support compliant fiscal operations.

In Uruguay, the certification obligation applies to the software used to issue e-Receipts and other electronic fiscal documents, not to the POS application itself. This means that retailers must use a compliant software solution capable of generating electronic documents in the required XML format, digitally signing them, sending them to the Tax Authority, and receiving the Tax Authority’s responses.
Before operating in production, taxpayers must complete a technical certification process. This includes testing the system, passing homologation with the TA, and receiving authorization as an electronic issuer.
The testing phase is mandatory and focuses on validating the technical correctness of the system. The Tax Authority provides tools to check the XML structure, digital signature, messages, reports, and response handling.
After successful testing, the taxpayer may enter the homologation environment. In this stage, the system is tested in controlled conditions by simulating real issuance flows. The process checks whether the software can generate XML documents, sign them correctly, transmit them to the TA, and process the responses.
Once the taxpayer passes homologation, it can move to the production environment and start issuing real electronic fiscal documents, including e-Receipts for B2C transactions and e-Invoices for B2B transactions.
The certification is not time-limited. Once approval is granted, there is no regular renewal requirement. However, the software must continue to comply with the Tax Authority rules, and non-compliant operation may lead to penalties or loss of authorization.
Software providers also have a specific role in the system. They may register in the Authorized Provider Registry and support taxpayers with implementation, onboarding, and integration.
In practice, Uruguay’s certification process ensures that the software can correctly issue, sign, transmit, report, and archive electronic fiscal documents before a taxpayer starts live fiscal operations.
