The problem
Hours, deliverables, approved changes, and expenses live in different places when it is time to invoice.
A late invoice is easy to miss when payment status, messages, reminders, and the client relationship are separated.
Invoicing looks simple until the freelancer also needs estimates, projects, files, scheduling, CRM, expenses, and reporting.
The product
Email, SMS, calls, and voicemail land beside the client record — with AI summaries, so anyone on the team can reply with full context.

Tasks, files, and status for every engagement — visible to the team and, through the client portal, to the client.

Send quotes, bill milestones or retainers, and let automated reminders chase anything outstanding.

Clients watch progress, files, and invoices in a branded portal instead of asking your team for updates.

Workflow
Keep contact details, notes, requests, estimates, proposals, files, and accepted work together.
Use projects, tasks, time entries, expenses, products, and notes to preserve the work behind the total.
Create invoices, payment links, deposits, retainers, plans, and credits from the same client record.
Review status, communication, overdue work, and reporting without opening a second system.
