What is client portal

A Client Portal is the space where you meet your clients and partners in one place. A great client portal doesn't require any learning curve from your clients. If a client portal looks like a Project Management tool, your clients won't use it. From years of experience, the best engaging client portal must look and feel like a secure microsite, because all people know is how to navigate websites. That's exactly how we built FuseBase Portals: a one-stop shop for all your client collaboration with no learning curve, matching your brand identity.

Frequently asked questions

How does client portal software work?

FuseBase provides internal and external workspaces. External workspace = client portal. These are special areas that have the look and feel of a microsite with protected access. Your clients and partners don't need to learn how to use them. Every client portal has all the necessary tools for your client collaboration. Additionally, FuseBase lets you build apps that you can connect to and use to ex

What's the difference between client portal software and a project management tool?

Project management tools are built for tech-savvy users, and they DO require onboarding and training. You don't want to overwhelm your clients; that's why you need a special area with zero learning curve for your clients and partners. PM tools look and feel heavy, unlike client portals, which are specifically designed for service delivery and external collaboration. The last thing you want is to f

What is client collaboration software?

Client collaboration software is specifically designed to enable your internal team to collaborate with external team members, such as clients/partners/vendors, in a way where they don't need to learn how to use it. Client collaboration software has workspace areas with all advanced tools, including CRM, Project Management, Billing, Invoicing, etc., and external workspaces - client portals. These

How is FuseBase different from Notion, SharePoint, or Confluence?

These tools are primarily built for internal collaboration, and these are great tools! However, we believe that they are not fully optimized for client collaboration, e.g., lack of advanced client permissions, branding and customization, and client portal areas that are specifically designed for external users such as clients/partners/vendors. FuseBase brings both worlds: internal collaboration an

Can I white-label FuseBase with my own brand?

Yes, FuseBase provides multiple options. You can fully white-label your FuseBase organization by connecting it to your subdomain.

Can I build client-facing apps inside FuseBase?

Additionally, you can connect FuseBase apps to your domains and make them fully whi

Does FuseBase work for agencies and consulting firms?

Yes, FuseBase is built for client-facing teams and businesses. That's why FuseBase provides internal and external workspaces.
