Client portal and billing software

Client portal and billing software for a calmer client experience.

Clients should not have to chase links, ask for status, or wonder how to pay. Workspace369 helps businesses keep requests, shared files, proposals, invoices, payment links, and communication organized around the client.

Key facts

Client portal and billing software at Workspace369 covers 10 areas, including client records and profiles, requests and forms, shareable files and permissions.

The workflow runs in 4 steps, from "collect clean intake" to "follow up without chaos".

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

What clients feel when systems are scattered

Too many separate links

One link for intake, another for files, another for invoices, another for payment, and no obvious source of truth.

Status updates become manual

Teams repeat the same answers because client requests, files, messages, and billing are not connected.

Payment friction delays cash

Payment links, deposits, plans, reminders, and invoice status need to be easy for both the business and the client.

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.

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

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.
