Welcome to the December 2025 edition of our monthly FinOps feature roundup. Each month, we highlight the latest Ternary innovations designed to improve cost transparency, boost operational efficiency, and strengthen collaboration across teams.
In November, we announced the private beta of the Ternary Optimization Hub, improvements to the Billing Rules Engine, and new capabilities in MSP Billing Statements. Our December 2025 FinOps roundup introduces Bring Your Own Data integration, a new report type, and enhancements to cost reallocation rules.
Read on to explore how these enhancements help you maximize the value of your technology investments.
Introducing Bring Your Own Data: A unified view of technology spend
We’re excited to introduce Bring Your Own Data (BYOD), a new capability that allows you to import any time-series spend data into Ternary.
BYOD extends our FOCUS-based ingestion pipeline beyond native cloud billing to unify total technology spend within a single system. With BYOD, you can now bring in SaaS costs, data center expenses, internal finance outputs, revenue data, and more!
Data can be ingested from a cloud storage bucket or a BigQuery table using schema-agnostic mapping. No custom code, per-vendor adapters, or data limits are required.
By combining cloud and non-cloud data into a single source of truth, Ternary enables finance, engineering, and executive teams to analyze total cost of ownership, unit economics, margins, and profitability. This gives you the power to connect technology spend directly to business outcomes at enterprise scale.

Track spending trends with Variance Reports
In December, we introduced a new Variance Report chart type in the Ternary Reporting Engine. Variance Reports help you quickly understand how recent cloud spend compares to historical averages for the same time period.
This report makes it easy to analyze trends across flexible time ranges, such as the last 30 days by day, the last 90 days by week, or an entire quarter by month. You can break down variance by services, business units, or any dimension you choose, so it’s clear which areas are trending higher or lower than expected.
By highlighting deviations from normal spending patterns, the Variance Report helps you:
- Spot emerging cost anomalies early
- Confirm the impact of optimization efforts
- Understand how spend is shifting over time
You can use it to stay proactive and make faster, more informed decisions about cloud spend.
Preview and validate cost reallocation rules
We’ve enhanced the Ternary Billing Rules Engine to make cost reallocation easier to build, validate, and trust. The new guided, step-by-step rule creation flow walks you through clear stages, reducing errors and simplifying even complex reallocations.
While configuring a rule, you can now preview source cost data directly in a report. This helps you validate filters, groupings, and assumptions before you save.
After execution, you can view the rule’s impact in a report to clearly understand how costs were reallocated, troubleshoot issues, and refine logic as needed. With these enhancements, you can also more easily distinguish between reallocated and non-reallocated costs.
The Ternary team is here to support your FinOps journey. Thanks for reading our December 2025 FinOps roundup. Stay tuned for next month’s updates!
