We compared ten tools on four kinds of collaboration: chat, meetings, shared documents and working with people outside the company. Most tools are strong at two of the four.

Disclosure: this guide is written by the team that makes Arpixa, which is one of the tools ranked. Every tool is scored on the same criteria, using vendor documentation and public pricing, and we point out where another tool is the better fit.
The short answer
Slack is the best collaboration tool overall, for fast chat and the widest integrations. Microsoft Teams is the best value inside Microsoft 365, and Zoom the most reliable for video. Arpixa ranks seventh: it is not a chat or video tool, but it is the strongest here for collaborating with clients.
Internal collaboration is well served. External collaboration, with clients, freelancers and partners, is where most stacks break down: people get added to tools they do not want, or left out of decisions that affect them.
Chat and meetings are what most teams buy collaboration software for, so Slack, Teams and Zoom take the top spots. Tools built for one job, such as client collaboration or documents, rank lower overall and may still be the right pick for that job.
Pricing: Free to $7.25/mo Edge: Superior chat features Fit: Communication-centric teams
Best for real-time team communication. Slack excels as a communication hub, offering channels, direct messages, and voice/video calls to keep teams connected. Its primary strength is facilitating rapid, organized conversations and extensive third-party app integrations. However, managing notifications and avoiding information overload can be a significant challenge for larger teams.
Strengths
Exceptional real-time chat
Robust third-party integrations
Organized channel discussions
User-friendly interface
Quick file sharing
Where it falls short
Can lead to notification fatigue
Limited built-in project management
2
Microsoft Teams
Collaborate smarter, connect seamlessly.
8.5out of 10
Pricing: Free to $4/mo Edge: Deep Microsoft 365 integration Fit: Microsoft-centric businesses
Best for Microsoft 365 ecosystem users. Microsoft Teams provides a comprehensive suite for collaboration, tightly integrated with the Microsoft 365 ecosystem, offering chat, video conferencing, and document co-editing. Its strength lies in its seamless compatibility with other Microsoft applications, making it ideal for existing users. A key trade-off is its resource-intensive nature, sometimes slowing down older systems.
Strengths
Excellent Microsoft 365 integration
Robust video conferencing
Secure guest access
Comprehensive file sharing
Integrated document co-editing
Where it falls short
Can be resource-heavy
Interface can feel cluttered
3
Zoom
Connect visually, communicate clearly.
8.3out of 10
Pricing: Free to $14.99/mo Edge: Superior video quality Fit: Remote-first teams
Best for high-quality video conferencing. Zoom is renowned for its industry-leading video conferencing capabilities, providing stable, high-definition calls for various team sizes. Its main strength is unparalleled reliability and ease of use for virtual meetings and webinars. The primary limitation is its less robust feature set for comprehensive project management or persistent team chat outside of meetings.
Best for cloud-native productivity suite. Google Workspace offers a tightly integrated suite of productivity and collaboration tools, including Gmail, Drive, Docs, and Meet, all accessible from the cloud. Its strength lies in providing a familiar, web-based environment for document creation, storage, and communication. A drawback is that its project management features are less specialized compared to dedicated platforms, requiring reliance on third-party integrations.
Strengths
Familiar, intuitive interface
Excellent real-time co-editing
Generous cloud storage
Strong security features
Seamless Gmail, Calendar integration
Where it falls short
Less specialized project tools
Can be overwhelming for new users
5
Notion
All-in-one workspace for your team.
7.9out of 10
Pricing: Free to $8/mo Edge: Highly customizable workspace Fit: Information-heavy teams
Best for flexible knowledge management. Notion serves as an incredibly flexible workspace, allowing teams to create custom wikis, databases, documents, and project boards tailored to their specific needs. Its core strength is its unparalleled adaptability and capacity for consolidating diverse information. The primary trade-off is a steep learning curve for new users, making initial setup and adoption challenging.
Pricing: Free to $10.99/mo Edge: Superior task management Fit: Project-driven teams
Best for structured task and project management. Asana is a robust project management tool designed to help teams organize, track, and manage their work from start to finish. Its main strength lies in its intuitive task management, clear project views, and workflow automation. A significant trade-off is its less emphasis on real-time communication, often requiring integration with other chat tools.
Pricing: Free plan, then from $12/mo Edge: External collaboration with clients Fit: Agencies and service firms
Best all-in-one option for collaborating with clients. Arpixa is built for the external side. Clients see projects, deliverables, documents and invoices in a branded portal, approve work there and message the team by topic. Internally, a shared workspace inbox keeps updates and handoffs together. It does not replace a real-time chat app or a video platform, so expect to keep Slack, Teams or Zoom for those.
Strengths
Clients collaborate in their own branded portal
Approvals and messages are recorded with the project
Pricing: Free to $8/mo Edge: Highly visual interface Fit: Creative and marketing teams
Best for visual project and workflow management. Monday.com offers a highly visual platform for managing projects, tasks, and workflows, utilizing customizable boards and intuitive interfaces. Its primary strength is its flexibility and visual appeal, making complex projects easier to track at a glance. However, the platform can become costly as teams scale, and some users find its extensive features overwhelming.
Pricing: Free to $7/mo Edge: Extensive feature set Fit: Versatile project teams
Best for all-in-one customizable workspace. ClickUp aims to be an all-in-one productivity platform, consolidating tasks, docs, chat, goals, and more into a single customizable workspace. Its strength lies in its extensive feature set and customization options, catering to almost any workflow. The main trade-off is that its sheer number of features can be overwhelming and lead to performance issues or a steep learning curve.
Pricing: $15/mo per user Edge: Simple, focused design Fit: Small, agile teams
Best for simple, focused project communication. Basecamp focuses on providing a straightforward platform for project management and team communication, emphasizing simplicity over extensive features. Its strength is its uncomplicated approach to keeping projects on track with clear message boards, to-do lists, and schedules. The key trade-off is its limited advanced functionality, which may not suffice for complex projects requiring intricate workflows or deep integrations.

Before you buy
Mistakes we see buyers make
01
Adding a tool for every conversation
Each new tool is another place to check. Agree which tool is for which kind of conversation before adding more.
02
Making chat the record
Important decisions should be written where the work lives, not left in a scrolling channel.
03
Forgetting external people
Clients and freelancers need a simple way in. Check guest access and what they can see before you commit.
04
Ignoring notification fatigue
Tools that ping constantly reduce focus. Look for quiet defaults and digest options.

Questions
About this review
Slack, for most teams: fast chat, huddles and thousands of integrations. Microsoft Teams is better value if you already pay for Microsoft 365.
Not exactly. Arpixa handles collaboration around client work: projects, files, approvals and client messages. Many teams use it alongside Slack or Teams for quick internal chat.
Record decisions where the work lives, such as on the project, deliverable or document. Chat is good for quick questions and poor as a record.
Shared channels can work for close partners, but they mix client talk with internal chat. A client portal with topic-based messages keeps client conversations organised and separate.
Slack has the better chat experience and integrations. Teams is better value if your organisation already pays for Microsoft 365.
Not if you use Teams or Google Workspace, which include video. Arpixa adds Google Meet links to client meetings.
Many teams collaborate primarily through their project tool, with comments and files on tasks. They are strong for internal work and lighter on client collaboration.
A combination usually works best: Slack or Teams for chat, Zoom or Teams for calls, and a shared workspace for decisions. Teams working with clients should add a portal like Arpixa.
Yes, especially for teams that want fewer notifications and flat pricing. It also supports inviting clients to projects.
Project and client collaboration, chat and meetings, documents and files, and visual or async tools. Most teams need one tool in each.
