The problem
Consulting invoices depend on more than a total
Retainers require manual reconciliation
Hours, milestones, recurring work, credits, and remaining value become spreadsheet work.
The client asks for context
A billing question requires searching meeting notes, email, files, project boards, and payment history.
The product
See the workspace your clients feel.
01
Every channel in one inbox
Email, SMS, calls, and voicemail land beside the client record — with AI summaries, so anyone on the team can reply with full context.
02
Client work, organized as projects
Tasks, files, and status for every engagement — visible to the team and, through the client portal, to the client.
03
Proposals to paid invoices
Send quotes, bill milestones or retainers, and let automated reminders chase anything outstanding.
04
A portal clients actually check
Clients watch progress, files, and invoices in a branded portal instead of asking your team for updates.
Workflow
From consulting proposal to paid engagement
01
Define the engagement
Use client records, proposals, estimates, notes, files, and accepted scope to create a shared starting point.
02
Deliver with a record
Track projects, tasks, calendar events, time, expenses, decisions, messages, and files as the work develops.
03
Bill the right model
Support invoices, retainers, deposits, payment plans, credits, and payment links without losing the engagement context.
04
Review the relationship
See client activity, revenue, expenses, receivables, project status, and follow-up in one workspace.
