About.app

NexusOS is the operating system for modern agencies — one place to plan, deliver, bill, and delight clients.

Is my data isolated per client?

Yes. Role-based access means founders, team, and clients each see only what they should — zero leakage across organizations.

Does it support GST invoicing?

Fully. Generate GST-compliant tax invoices with CGST/SGST, HSN codes, and amount-in-words, exportable to PDF.

What does the AI studio do?

It drafts SOPs, proposals, status reports, and task breakdowns in seconds, and exports to PDF or Word.

ONE WORKSPACE

Stop stitching ten tools together.

Trello, spreadsheets, WhatsApp, Drive, a separate invoicing app — every context switch costs you. NexusOS puts projects, tasks, docs, billing, AI and clients under one roof, with one login and one source of truth.

  • Role-based views for founder, team and client
  • Zero data leakage across organizations
  • Everything searchable in one place
AI THAT DOES THE WORK

Turn an hour of admin into thirty seconds.

The AI Studio drafts SOPs, proposals, status reports and full task breakdowns from a one-line prompt — then exports clean PDF or Word, on your letterhead, with no filler and no third-party branding.

  • SOPs, proposals, reports & decks
  • Task breakdowns from a single prompt
  • Export to PDF / Word instantly
CLIENTS WHO TRUST YOU

A portal that makes you look enterprise.

Give every client a branded portal: live project status, shared documents, invoices and a direct line to your team. No more 'I'll check and get back to you' — the answer is already there.

  • Branded, white-label client portal
  • Live status, files & invoices
  • Direct client ↔ team messaging

“We replaced five tools with NexusOS. Our project handoffs, invoices and client updates now live in one place — and the AI drafts in seconds what used to take an afternoon.”

FAQ

Questions, answered.

Is my data isolated per client?

Yes. Role-based access means founders, team members and clients each see only what they should. Client organizations are fully partitioned — zero leakage.

Does it support GST-compliant invoicing?

Fully. Generate proper tax invoices with CGST/SGST splits, HSN codes and amount-in-words, then export to PDF or share via the client portal.

What can the AI Studio actually generate?

SOPs, proposals, status reports, presentations and task breakdowns — from a short prompt. Output is clean and unbranded, exportable to PDF or Word.

Can I bring my whole team on?

The Scale plan includes 25 seats across departments — development, branding, content, AI, automation and more — with capacity and utilization tracking built in.

How long does onboarding take?

Most agencies are live the same day. Start the free trial, import your projects and clients, and invite your team — no migration project required.
