Spend management

Available on: Pro projects.

A Pro project keeps working beyond its included usage, and the extra is billed as on-demand usage at the on-demand rates. Spend management decides how far that can go. It’s set per project, so a limit on one project doesn’t affect the others in the team.

What counts toward on-demand usage

Everything a Pro project uses beyond its included usage:

API requests, database capacity and asset storage;
agent chat turns, automation runs and agent steps;
sandbox compute.

These don’t count: seats, and AI model usage paid from AI credits. AI credits have their own monthly ceiling for automatic top-ups.

Choose a mode

Open the project’s Settings → Spending. The On-Demand Usage card has three modes:

Mode	What happens beyond the included usage
Unlimited (default)	Usage continues and is billed. Flexkit emails the billing contacts every $50 of on-demand usage.
Fixed	Usage continues up to the Monthly Limit you set, in US dollars. At the limit, the project is paused until the 1st or until you raise the limit.
Disabled	No on-demand usage. The project is paused once it uses up its included API requests, database capacity or asset storage, and the agent stops at its monthly allowance.

Open the project’s settings

Go to the project, then Settings → Spending. The tab appears only on Pro projects.

Pick a mode

Choose Unlimited, Fixed or Disabled. For Fixed, enter the Monthly Limit.

Save

If the project has already used more than the new setting allows, Flexkit tells you it’ll be paused and asks you to confirm with Save and pause.

Team Owners and team members with the Billing role can change these settings.

How Flexkit checks your usage

Flexkit evaluates every project’s usage every 5 minutes. Usage that arrives between two checks still counts, so a project can go slightly past a Fixed limit before it’s paused. Leave some margin if the limit is a hard budget.

The limit applies to the calendar month (UTC). On the 1st, on-demand usage starts again from zero, and a project paused by its Fixed limit resumes automatically.

Alerts

Flexkit emails the team’s billing contacts (the billing email, team Owners and Billing members):

When	Email subject
The project reaches 50%, 75% and 100% of its included usage	Project reached 50% of included usage
A Fixed project reaches 75% and 90% of its monthly limit	Project reached 75% of its monthly spending limit
An Unlimited project passes each further $50 of on-demand usage	Project has $100.00 of on-demand usage this month
The project is paused, or restored	Project is paused / Project is no longer paused

See notifications for every billing email.

What a pause does

A paused project stops serving its GraphQL API, and its automations and agent chat stop. Studio shows a Project paused message and doesn’t save changes. Your data is kept.

A pause stops your application’s access to Flexkit. Before choosing Fixed or Disabled for a production project, make sure your application handles failed API requests.

Restore a paused project

How you restore a project depends on why it was paused:

Fixed limit reached: raise the Monthly Limit, or switch to Unlimited.
On-demand usage disabled: switch to Fixed or Unlimited, or bring usage back under the included amount. API requests reset on the 1st; database capacity and asset storage go down when you delete data.

The project is restored as soon as you save. The Unpause button in Settings → General only lifts a pause you set yourself; it can’t override a spending pause. See project lifecycle.

Pause a project yourself

Project Owners can pause a Pro project at any time from Settings → General, for example to stop all usage while you investigate something. It stays paused until someone chooses Unpause. See pause deliberately.
