Two kinds of project
A sub-project is just a project with a parent. The relationship is single-level: a sub-project can’t have its own sub-projects.
Sub-projects share billing identity, not data. Each project’s CRM records, content, workflows, integrations, and team membership are still its own — being a member of the parent does not automatically grant access to a sub-project. Only the plan and credit pool are shared.
Credits are one shared pool
The parent project holds the credit balance. Whenever any project — the parent or one of its sub-projects — uses a credit-consuming feature (AI generation, agents, enrichment, …), the cost is drawn from that single parent pool. There is no separate balance per sub-project. Usage is still attributed per sub-project, so you can see how much each client consumed — but every charge draws down the same parent balance, and the monthly refill replenishes that one pool on the parent’s billing cycle.Plan & entitlements are inherited
A sub-project runs on the parent’s plan. Upgrade the parent to Pro and every sub-project immediately gets Pro entitlements and the larger monthly credit allotment; there’s nothing to upgrade on the children. The same is true for custom plans — the parent’s entitlements apply across all of its sub-projects.Where to manage it
Everything billing lives on the parent (top-level) project: the subscription and plan, the payment method, invoices, credit balance, top-ups, and the per-client usage breakdown. Open the parent project and go to Billing. Sub-projects have no billing screen — the dashboard sends you to the parent with a note that “billing is managed by the parent project.” This is the whole point of the model: one place to manage money, however many client workspaces you operate.Good to know
- Single level only. A sub-project can’t have sub-projects.
- Deleting a sub-project doesn’t lose any credits — it never held a balance. Its past usage stays on the parent’s history (shown as a deleted client) so your records stay intact.
- You can’t delete a parent while it still has sub-projects — remove or reassign the children first.
- Spinning up clients. Creating a sub-project (and configuring it from a template) over the API automatically attaches it to the parent’s billing — see Building a client onboarding funnel.
