# Expenses

Group: PSA

[Open in the interactive reference](https://docs.api.lensing.ai/lensing/v1/groups/psa-expenses)

An expense is a cost recorded on a PSA project and can be assigned to one of the project's expense budgets.

You can read expenses but not change them: there is no endpoint to create, change, or delete an expense or an expense budget, or to assign an expense to an expense budget.
