For years, "Cloud Cost Management" meant AWS, Azure, and Google Cloud. But in 2025, for many digital natives, the SaaS bill (Snowflake, Datadog, MongoDB Atlas, OpenAI) rivals the infrastructure bill. The challenge? AWS bills in "Instance Hours," Snowflake bills in "Credits," and Datadog bills in "Host Hours." Merging these into a single report used to be an ETL nightmare.

Enter FOCUS 1.2 (FinOps Open Cost and Usage Specification). This standard has finally normalized the chaos of SaaS billing.

The Problem: Apples and Oranges

Legacy SaaS billing exports were proprietary CSVs.

• Snowflake: Column CREDITS_USED_CLOUD_SERVICES

• Datadog: Column avg_container_count

Trying to UNION ALL these with AWS CUR data was impossible without massive transformation logic.

The Solution: FOCUS 1.2 SaaS Columns

FOCUS 1.2 introduces standardized columns that abstract the underlying unit of measure.

1. BilledCost: The universal currency column. Whether it was Credits or Hosts, this is what you pay in USD.

2. PricingUnit: The abstraction layer. For Snowflake, this value is "Credit". For OpenAI, it is "Token".

3. UsageQuantity: The raw consumption count.

SQL Example: Normalizing Snowflake Data

Here is how you map a raw Snowflake export to the FOCUS schema:

SQL

SELECT
  'Snowflake' AS ProviderName,
  'SaaS' AS ServiceCategory,
  'Data Warehouse' AS ServiceName,
  start_time AS ChargePeriodStart,
  warehouse_name AS ResourceId,
  credits_used_compute AS UsageQuantity,
  'Credit' AS PricingUnit,
  (credits_used_compute * 3.00) AS BilledCost -- Assuming $3/credit contract
FROM snowflake_usage_history;

The "Single Pane of Glass"

Once normalized into the FOCUS format, your SaaS spend sits alongside your EC2 spend. You can now run a single SQL query to answer executive questions like: "What is the total cost of our Data Platform?" (Summing AWS S3 + Snowflake + Datadog monitoring) or "Who are our top 5 vendors by spend?".

Implementation Strategy

1. Ask Vendors for FOCUS: In late 2025, major vendors like Datadog and Snowflake offer native FOCUS-compatible exports. Enable them in the billing console.

2. Use Open Source Converters: For vendors lagging behind, use the FinOps Foundation's open-source FOCUS Converters (Python-based) to transform proprietary CSVs into the standard schema before loading them into your data lake.

Verdict: FOCUS 1.2 turns SaaS spend from a "black box" into a queryable data asset. It is the prerequisite for total IT cost governance.
