## Alias

An alias links MetraTech to external accounts so that billing data for subscribers can be retrieved from external systems. To ensure that subscribers are accurately billed, all MetraTech accounts must be linked to the correct external accounts. This is done through aliases, which involves linking MetraTech account IDs with unique identifiers (aliases) to the associated account in the external system. If accounts are not accurately linked via aliases, the transactions associated with the accounts fail and end up in a System Failures log.
