Virtual tags

Every dollar has an owner.

See spend by team, product, or any other dimension across Cloud, SaaS, and AI, ready for showback and chargeback. You build the rules from your own bills and apply them up to 12 months back.

A LevelFour board card with twelve months of cost by team, across providers

Cost allocation with no tagging project

Native tags stop at each provider, and plenty of spend never carries one: shared accounts, support fees, AI seats billed per person. Virtual tags read the bills instead, so finance gets one view of Cloud, SaaS, and AI spend and your engineers retag nothing.

A virtual tag rule whose values come from the bills of several providers

Build tags from your own bills

Define tag keys and values with rules, and fix tagging hygiene without waiting on engineering. You tick accounts, services, people and workloads off your providers' bills, and LevelFour runs each new cost line through your rules.

A virtual tag's page with every provider it reads and the spend of each value

Unify tags across every provider

One tag covers your cloud bills, AI tools, data platforms and Kubernetes clusters, including providers with no native tags. A team's database, its pods and its AI seats land on one value, ready for showback and chargeback.

A shared cost split between four teams by percent

Re-allocate shared costs

Give each team its share of support plans, shared clusters and AI subscriptions. You split them by percent, evenly, the way another tag already divides cost, or by the usage you send.

The settings that apply a tag to past cost and override a provider's tag

Back-fill history and override provider tags

Apply a new tag up to 12 months back, and your first report already shows a trend. If a provider tag and your rule disagree, you choose which one wins. You also name the line for cost no rule claims.

An AI agent creating a virtual tag and editing it over MCP

Create and edit tags with AI agents, over MCP

Ask an AI agent to create a tag, change a rule or rename a value. It picks from the values on your bills and previews the change before saving, so a new allocation takes one sentence.

The Tags page with tagged spend, untagged spend and its virtual, predefined and provider tags

Track tagging coverage

See how much of your spend carries a tag and how much stays untagged, across provider and virtual tags. You also get 19 predefined tags, such as AI Spend and the FOCUS fields, before you write a rule.

Virtual tags documentation

The docs cover rules, splits and predefined tags. The API, the CLI and the SDKs read and write the same tags.
