in Costory give engineering teams monthly cloud cost budgets with built-in budget alerts. Instead of maintaining spreadsheets, you define budget lines by , assign owners, and monitor Budget, Actual, Forecast, and Delta in one place.

Cloud cost budgets for engineering teams

Use Budgets when you need clear spend guardrails that map to engineering ownership:
  • Replace manual spreadsheet updates with a budget table that tracks Budget, Actual, Forecast, and Delta by line
  • Assign owners per budget line to improve accountability
  • Trigger alerts when actual spend or end-of-month forecast crosses a threshold
  • Keep multiple budget versions and compare decisions over time
Budgets are monthly. Each line can have a different owner, so the engineer or manager who controls the spend gets the signal first.

Set up cloud cost budgets and budget alerts

1

Create a new budget and choose the scope

Open Budgets and click Create a new budget. Select the monthly range you want to manage and choose the Virtual Dimension that splits costs into budget lines, for example team, business_unit, or environment.
2

Choose your budget metric

Select the currency and cost metric used to evaluate budget performance. Pick the metric your stakeholders already use for monthly reviews.
3

Choose a fill method

Initialize the monthly budget values with one of the available strategies.
Fill methodWhen to use
ManualYou already have approved values and want direct control
Import CSVFinance prepared values in a spreadsheet
Last year + x%You want a simple growth model on last year’s baseline
Last x months + y%You want a moving baseline with growth applied
4

Assign owners to budget lines

Set an owner for each line so alerts and reviews go to the right person. This keeps accountability distributed across teams instead of centralized in one role.
5

Configure budget alerts

Monitor specific budget lines and add threshold rules. You can alert on:
  • Actual spend exceeds threshold
  • Forecasted end-of-month spend exceeds threshold
Send alerts by Email or Slack, and include line owners in notifications for faster escalation.

6

Save and manage versions

Save the configuration as a budget version. When assumptions change, create a new version and keep past versions for historical tracking and auditability.

Key capabilities for engineering budget workflows

Monthly budgets by business dimension

Use Virtual Dimensions to structure budgets around how your organization operates. You can budget per team, product, environment, or any business mapping already used in Costory.

Forecasting with TimesFM

Costory uses TimesFM by Google to forecast end-of-month values for each budget line. This helps you escalate risk before an overrun appears in invoiced costs.

Multi-version tracking

Budgets support version history, so you can:
  • Keep the original baseline
  • Introduce a revised plan
  • Compare past assumptions with current outcomes

Owner-based accountability

Each budget line can be assigned to a specific owner. This enables practical showback, because teams can see their own target, actual spend, forecast, and delta in one place.

Budget alerts for faster response

Alert rules reduce manual monitoring overhead. Teams get notified when spend risk appears, then can jump to Cost Explorer to find the root cause and take action.

Use cases

VP Infrastructure review with engineering leads

Track all team budgets in one table and review which lines are on track, at risk, or exceeded before month end.

Team-level showback

Give each engineering manager clear visibility into their budget line and ownership of follow-up actions.

Escalation when forecasted spend drifts

Trigger an alert when a forecast crosses a threshold, then investigate the driver in Cost Explorer and coordinate with the line owner.

Frequently Asked Questions
