Track costs with tagging

You can use tags to categorize and track your Amazon costs. When you apply tags to your Amazon resources, including Firehose streams, your Amazon cost allocation report includes usage and costs aggregated by tags. You can organize your costs across multiple services by applying tags that represent business categories (such as cost centers, application names, or owners). For more information, see Use Cost Allocation Tags for Custom Billing Reports in the Amazon Billing User Guide.
