These are invoice drafts that appear in the invoice review section, waiting to be checked, adjusted, and finalized into official invoice documents. **What gets included:** - Subscription billing rows that have passed their billing date - Time-based work (tasks with logged time) that has not been billed yet - Express quotations that have been accepted by customers - Products and components that are ready for billing - Manual positions and interim payments **What data is returned:** - List of all potential invoices grouped by project, organization, and billing period - Each potential invoice includes the billing period (dateFrom, dateTo), total net amount, and invoice type - Results are automatically filtered based on project access permissions - Each entry shows which organization and project it belongs to **Invoice Types:** - **Mixed**: Combined invoice with multiple billing types (time, subscriptions, products, components) - **Subscription**: Recurring subscription billing only (monthly or periodic fees) - **TimeBased**: Time-based work (logged hours on tasks) only - **ExpressQuotation**: Accepted express quotations only (quick add-ons from tickets) - **SingleProject**: Single project invoice (project-based billing) - **InterimPayment**: Interim or advance payment invoice **How it works:** The system automatically creates potential invoices when billable items become due. For example, completed tickets appear as time-based items, subscriptions generate entries on their billing dates, and accepted express quotations become billable immediately. **Permission requirements:** Requires Invoices.manage permission to view potential invoices. Results are scoped to projects you have access to.
