Project Billing
Project billing charges customers for work according to agreed terms, such as fixed price, milestones or time and materials.
Definition
In general ERP practice
Project billing charges customers for work according to agreed terms, such as fixed price, milestones or time and materials. Billing quantity and project profitability answer different questions.
In Odoo
Odoo connects project services to sales-order lines and their invoicing policies. Timesheet-based billing uses eligible recorded hours, while milestones and expenses have their own configured workflows; invoice generation remains distinct from cash collection.
