Retainer & Project Billing

Retainer hours tracked in a notebook are hours that quietly go unbilled. We build the billing system that captures every hour and generates invoices automatically.

What we build

• Retainer tracking: Hours logged against each client's retainer, with overage flagged automatically.
• Project invoicing: Fixed-fee and hourly project invoices generated from tracked work.
• Payment tracking: Outstanding invoices tracked with automatic follow-up reminders.
• Revenue reporting: Monthly recurring revenue and project revenue visible at a glance.

Implementation scope

Billing connects to project tracking, so invoices always reflect actual hours and deliverables completed.
