Invoicing and project management software

Invoicing and project management software for work and money in one place.

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 10 seats, 500 GB of storage, and 120,000 AI tokens per month at $299/mo.

Additional seats cost $15 each and 100 GB of additional storage costs $15; full pricing is public on the Workspace369 pricing page.

The problem

Where project and billing systems break

The scope changes, but billing does not

Change orders, retainers, deposits, payment schedules, and credit notes need the same context as the work plan.

Finance only sees the invoice

The real story includes tasks, time, expenses, files, status, client messages, and payment history.

Project profitability arrives too late

Owners need to see AR, expenses, and project financials while decisions can still be made.

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.

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

A cleaner path from scope to cash

01

Scope and quote

Use estimates, proposals, service catalogs, optional line items, and public proposal URLs to package the work.

02

Deliver the project

Manage tasks, subtasks, files, comments, calendar views, dependencies, templates, and workload visibility.

03

Invoice accurately

Create branded invoices, recurring invoices, change orders, retainers, payment plans, deposits, and credit notes.

04

Watch the numbers

Track payment status, expenses, AR aging, dashboards, project profitability, and accounting activity.

Loved on the App Store

Rated by the people running their client work on it.

Finally feels calm

Bounced between three or four all-in-one tools and always ended up in a mess of tabs. This is the first one that feels calm. Set up my client projects in ten minutes.

Painless team rollout

Rolled it out to our eight-person team and adoption was painless — intuitive and polished. One star off only because I'd love more integrations, but they keep shipping.

Samantha D. · Operations lead · App Store review
Hours back every week

Was juggling separate tools for notes, tasks, docs, and updates. Consolidating into one place has genuinely saved me hours each week. Support is responsive too.
