# Build your workflows once—apply them everywhere

Codify the GTM logic that is custom to your business, centralize it, and scale it across every table and audience in Clay. Your best logic becomes your org's default.

## What are functions?

### Centrally managed workflows

Package the enrichment logic that's custom to your business — your provider preferences, compliance checks, scoring criteria — into a single reusable workflow. Update it once, see your changes everywhere. Your team runs the function. You control what's inside.

## Frequently asked questions

### Can I reuse enrichment logic across multiple tables?
Yes. You can create a Function from any set of enrichment columns and instantly reference it across unlimited tables and workbooks.

### How do I make changes to a Function without breaking live workflows?
Functions have a sandboxed edit mode with publish diffs — so you can iterate safely without disrupting anything that's already running.
