Project billing should reflect what you’ve done: milestones, time, or both. PrimeBase lets you create invoices from the project, with line items tied to time entries or fixed fees. So what you bill matches what you delivered, and you can track revenue per project.
Bill projects accuratelyBill by milestone when the client has agreed to phases; bill by time when you’re on an hourly rate. Or mix both. PrimeBase keeps invoices linked to the project so you always know what’s been billed and what’s outstanding.
Invoices and costs live on the same project. You see what you’ve billed and what you’ve spent so margin per project is clear. That’s project billing software without spreadsheets or a separate invoicing tool.
