The scope changes, but billing does not
Change orders, retainers, deposits, payment schedules need the same context as the work plan.
Invoicing and project management software
When projects live in one app and billing lives in another, teams lose time reconciling what happened. Workspace369 connects the plan, the delivery details, the invoice, the payment, and the financial report.

Key facts
Invoicing and project management software at Workspace369 covers 10 areas, including project management, tasks and subtasks, kanban, calendar, and timeline views.
The workflow runs in 4 steps, from "scope and quote" to "watch the numbers".
Workspace369 starts at $29/mo for 1 seat, and the Commander plan includes 20 seats, and 120,000 AI tokens per month at $299/mo.
Additional seats cost $10 each; full pricing is public on the Workspace369 pricing page.
The problem
Change orders, retainers, deposits, payment schedules need the same context as the work plan.
The real story includes tasks, time, expenses, files, status, client messages, and payment history.
Owners need to see AR, expenses, and project financials while decisions can still be made.
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
Use proposals, quotes, service catalogs, optional line items, and public proposal URLs to package the work.
Manage tasks, subtasks, files, comments, calendar views, dependencies, templates, and workload visibility.
Create branded invoices, recurring invoices, change orders, retainers, payment plans, deposits.
Track payment status, expenses, AR aging, dashboards, project profitability, and accounting activity.
