**What are Project Subscription Billings?**
Project Subscription Billings allow you to manage recurring fees and charges for projects. This feature is ideal for SaaS subscriptions, maintenance contracts, support packages, or any recurring billing arrangement. The system automatically generates billing rows based on your date range and frequency settings, which can then be included in invoices.

**What data is returned:**
- All active subscription billing items for the specified project
- Items are sorted by their sort order (display order)
- Each item includes date range, payment type, price, frequency, and configuration details

**Payment types supported:**
- **fixed**: Fixed monthly fee (e.g., $500/month support package)
- **perUnit**: Variable pricing based on units (e.g., per user, per license)
- **oneTime**: One-time charge within the subscription period

**Use cases:**
- Retrieve all recurring billing items for a project
- Display subscription information in project dashboards
- Generate reports on recurring revenue
- Audit subscription configurations
