Client Portal Builder

Look like an enterprise. Charge like one too.

The Problem

Freelancers and small agencies share files via email, track projects in spreadsheets, and communicate through scattered channels. It looks unprofessional and creates friction. Enterprise clients expect a polished experience, but building a custom portal is expensive and time-consuming.

The Solution

A white-label client portal that agencies can set up in minutes. Custom branding, file sharing, project timelines, and secure messaging—all under your domain. Look like you have a 10-person team when it's just you.

How it works:

1

Create portal

Add logo, colors, domain

2

Invite clients

Email invite, secure login

3

Collaborate

Share files, track progress

Market Research

The freelance economy is massive (60M+ in US alone). Agencies need professional tools to compete with larger firms. Client portal tools like Copilot and Dubsado prove the market.

  • Dubsado raised $7M+ for client management—proves demand
  • 70% of clients prefer self-service portals (Forrester)
  • Average agency spends 5+ hours/week on client communication
