Does the tool provide visibility into budget limits vs actual spend?

Yes: Exivity Core, the metering and billing engine. Using the Budget Management feature of Exivity Core, organizations are able to set a budget for any business unit or project. A budget can be easily created for a single or multiple business entity. It is possible to configure annual budgets, but also quarterly and monthly depending on your business needs. Alerts can be sent out to each individual user in case a spending threshold is reached.
