FOCUS Specification

The FOCUS specification sets out a common structure for billing data. Before FOCUS, each cloud provider used its own data format, column names and definitions. AWS, Microsoft Azure, Google Cloud and other providers described similar concepts, such as list price, discounts and commitment purchases, in different ways. Organizations using more than one provider had to build and maintain complex transformations to combine the data. FOCUS defines a standard set of columns and rules so that billing data from different sources can be compared and combined directly.

FOCUS is developed by a working group of the FinOps Foundation that includes practitioners, cloud providers and tool vendors. Version 1.0 became generally available in 2024, and several later versions have expanded its coverage. Major cloud providers and many SaaS and FinOps tool vendors now offer FOCUS-formatted exports. For IT financial management, FOCUS reduces the effort of normalizing technology cost data and makes consistent reporting across providers more achievable.

Definition of FOCUS Specification

The FinOps Open Cost and Usage Specification is a technical specification that defines a standard schema for cost and usage data, including column names, data types, allowed values and the rules providers must follow when generating the data. It is maintained by the FinOps Foundation and published openly.

Providers that support FOCUS produce billing exports conforming to the specification, which customers can load into analytics tools or FinOps platforms without provider-specific transformation.

Key Concepts

FOCUS defines several cost measures for each charge. List cost reflects public prices, contracted cost reflects negotiated rates, billed cost is what appears on the invoice, and effective cost spreads upfront commitment payments over the period they cover. Having all four allows organizations to analyze savings and allocate costs consistently.

It defines standard categories for charges, such as usage, purchases, taxes, credits and adjustments, and for services, such as compute, storage and networking. It also standardizes how commitment discounts, billing accounts, regions, resources and tags are represented.

These shared definitions mean that a report built on FOCUS data works the same way regardless of which provider the data came from.

Scope and Adoption

FOCUS began with public cloud billing and has expanded to cover SaaS and other technology categories, reflecting the broader scope of FinOps.

Major cloud providers, including AWS, Microsoft Azure, Google Cloud and Oracle Cloud Infrastructure, offer FOCUS-formatted exports, as do a growing number of SaaS vendors. Many FinOps tools can ingest FOCUS data directly.

The specification continues to evolve, with new versions adding columns, clarifying definitions and covering more types of charges.

Importance of FOCUS in IT Financial Management

Most large organizations use more than one cloud provider and many SaaS vendors. Combining their billing data has traditionally required significant effort and expertise.

FOCUS reduces this effort and improves consistency. Data that once needed custom code for each provider can be loaded into the same tables and reports, and the definitions behind each column are documented publicly.

It also aligns with the FinOps principle that data should be accessible, timely and accurate, which explicitly calls for using FOCUS to improve normalization across technology categories.

Multi-Provider Reporting

With FOCUS data, organizations can build a single set of reports and allocation rules that apply across providers. This supports multi-cloud cost management and gives leaders a consistent view of total consumption-based spending.

Consistent definitions also make comparisons more meaningful, for example comparing the effective discount achieved with each provider.

For finance, standardized data simplifies the mapping of cloud costs to cost centers and the general ledger, supporting IT cost transparency.

Lower Effort and Lock-In

FinOps teams that previously spent much of their time transforming data can focus on analysis and optimization instead. New providers can be added to reporting with less work.

Because FOCUS is an open standard, organizations are less dependent on a single tool's proprietary data model, making it easier to change or combine tools.

Vendors also benefit, since they can support one standard format rather than building custom integrations for each customer and tool. This is one reason adoption has spread quickly among providers and FinOps tool vendors.
