Effective communication is one of the most important foundations of a successful small business. As teams grow, conversations quickly move beyond simple email threads. Employees need tools that allow them to chat in real time, collaborate on tasks, share files, and organize conversations by projects or teams.

In this article, we share our 5 best communication platforms for small businesses, focusing specifically on team chat and team collaboration aspects. These tools enable employees to communicate instantly, keep discussions organized, and collaborate without switching between multiple apps.

Table of Contents

1. Elastic Email Inbox

  • Combines Team Chat, Live Chat & Help Desk under one affordable roof
  • Very competitive pricing with a generous Free Plan and paid plan at $9/seat/month with no-limit message history and no hidden costs
  • Bridges internal and external communication
  • Built by Elastic Email - long-term expertise in email marketing and email delivery
  • Very new product with a limited track record and far fewer integrations, but it’s promising and constantly evolving and improving. 

After over 15 years of experience and expertise in the area of email marketing and email delivery, Elastic Email decided to expand its offering by entering the world of communication platforms. After the launch in fall 2025, Elastic Email Inbox is the newest entrant on this list, but it addresses a pain point that is very real for small businesses. It connects internal team communication and external customer communication under one roof. Most companies solve this by running two completely separate tools. For Elastic Email Inbox, these two worlds need not be separated at all. 

The platform is built around three integrated components: Team Chat for internal messaging, Live Chat for real-time conversations with website visitors, and a Help Desk for managing ongoing customer support threads. For small businesses, this unified approach can be particularly valuable. Teams can collaborate internally while also managing customer inquiries and support messages within the same platform. Instead of switching between multiple tools for internal chat, live chat, and email support, employees can manage everything from one workspace.

Another advantage is its cost-effective pricing, which makes it attractive for smaller organizations looking to simplify their communication stack. The free plan is really generous, offering all features with a limited message history (90 days). For unlimited message history, Elastic Email Inbox costs only $9/seat/month. 

Elastic Email Inbox is a very new product with a limited track record and far fewer integrations than its competitors, but the product is promising, constantly evolving and improving. 

Best for:

Elastic Email Inbox is perfect for small businesses and startups that handle customer support in-house and want to unify internal chat and external communication in a single, affordable platform.

2. Slack

  • Channel-based chat keeps conversations organized
  • 2,600+ integrations with tools like Google Drive, GitHub, and Trello
  • Excellent search and message history
  • AI summaries and workflow automation available
  • Huddles for quick, low-friction voice & video calls
  • Free version limits message history (90 days)
  • Many channels can create notification overload
  • Expensive for growing teams

Slack is one of the most recognizable team communication platforms in the world and is widely used by startups and small businesses. The platform is built around the concept of channels, which allow teams to organize conversations by projects, departments, or topics. This makes it easier to follow discussions relevant to employees’ work while avoiding unnecessary noise from unrelated conversations. Slack also offers powerful search functionality, which helps users quickly find previous messages, files, or links shared within the workspace. 

Another strength of Slack is its vast ecosystem of integrations. It connects seamlessly with 2,600+ productivity tools such as project management software, cloud storage platforms, and development tools. Also, features like “Huddles” allow for spontaneous audio and video calls with teammates.

However, its free version has a limited message history (90 days), and as more channels are created, the workspace can become overwhelming, especially if notifications are not carefully managed. For small businesses with limited budgets, the pricing of premium plans may also become a concern.

Best for:

It’s a great solution for growing startups, remote teams, and small-to-medium businesses that rely heavily on integrations and want the gold standard in chat user experience. 

3. Google Chat

  • Seamless integration with Docs, Sheets, Drive, and Meet
  • Simple interface and browser-based access
  • Spaces organize conversations by project
  • No extra cost if you already use Workspace
  • Gemini AI assistant embedded across all apps
  • Fewer integrations compared to Slack
  • Limited advanced collaboration features
  • Not ideal for complex workflows

Google Chat is a team messaging platform that is tightly integrated with the broader Google Workspace ecosystem. For organizations already relying on tools like Google Docs, Google Sheets, Google Drive, and Google Meet, Google Chat naturally becomes a central hub for team communication and collaboration. Employees can discuss projects while simultaneously sharing documents, editing files in real time, or launching meetings directly from the chat interface. Plus, Google Chat is included with most Google Workspace subscriptions, which means no additional costs. 

The platform offers a clean, intuitive interface that works directly in a browser, so teams can access conversations from virtually any device without installing additional software. Communication is organized through Spaces, which act as collaborative environments for projects, departments, or teams. Another important feature across all Google Workspace applications is the integration of the Gemini AI assistant. It can help summarize conversations, assist with writing messages, and streamline document collaboration. For small teams, this can reduce time spent on routine tasks and help maintain context across ongoing discussions. 

However, the platform does have limitations. Compared with tools like Slack, Google Chat offers fewer integrations and automation options. It can become a constraint for companies that rely on multiple specialized tools for project management, development workflows, or customer operations. Additionally, Google Chat lacks some of the advanced collaboration features found in more specialized platforms or highly structured project communication.

Best for:

Google Chat works best for small to medium businesses already using Google Workspace. Teams that collaborate heavily on shared documents, spreadsheets, and meetings will benefit the most from its seamless ecosystem integration and simple communication structure.

4. Discord

  • Free voice channels and screen sharing
  • Always-on voice channels reduce the need to schedule calls
  • Fast real-time chat
  • Highly customizable servers and bots
  • Unlimited message history
  • Designed originally for gaming
  • Limited business integrations
  • Lacks enterprise management features like task management, project tracking, or file version control
  • Limited compliance or security certifications (e.g., SOC 2, ISO 27001, HIPAA, FedRAMP)

Discord has evolved from a gaming communication platform into a versatile messaging tool used by online communities, developer groups, and increasingly by startups or remote teams. Its communication model is built around servers, which contain multiple text and voice channels dedicated to different topics or teams. The platform offers free voice channels and screen sharing, making it easy for team members to collaborate spontaneously. Unlike traditional meeting tools that require scheduling, Discord’s always-on voice channels allow employees to join conversations instantly. 

Messages appear instantly, and the platform supports a wide range of bots and automation tools that can add functionality such as notifications, moderation, or integrations with other services. Teams can customize their servers extensively by creating channels for different departments, projects, or topics. Another advantage is that Discord offers unlimited message history for free. 

Despite these strengths, Discord still carries several limitations for business environments. It was originally designed for gaming communities, and its interface and culture reflect it. While it works well for informal collaboration, some organizations may find it less professional compared to traditional workplace communication tools. Additionally, Discord has limited native business integrations and lacks built-in features for team management, like task management, project tracking, or advanced file version control. Compliance and security certifications commonly required by corporate environments, such as SOC 2, are also more limited.

Best for:

Discord is best suited for startups, creative teams, developer communities, and remote groups that prioritize real-time communication and informal collaboration. 

5. Mattermost

  • Full data ownership - self-host on your own infrastructure
  • Strong security & compliance for regulated industries
  • Open source and highly customisable via plugins
  • User-friendly and intuitive interface
  • Self-hosting requires technical knowledge to set up & maintain
  • Smaller ecosystem of integrations vs. Slack
  • Cloud-hosted pricing is not competitive for small teams
  • Less polished mobile experience than commercial alternatives

Mattermost is a powerful team communication platform designed for organizations that require greater control over their data and infrastructure. Unlike most cloud-based messaging tools, Mattermost allows companies to self-host the platform on their own servers, ensuring full ownership and control over sensitive information. It makes Mattermost particularly appealing to industries with strict compliance requirements, such as finance, healthcare, and government organizations. 

Mattermost’s interface is user-friendly and intuitive. Conversations are organized into channels, with support for threaded discussions, file sharing, and direct messaging. Because the software is open source, organizations can extend its functionality through plugins, custom integrations, and automation workflows tailored to their internal systems. 

However, the self-hosting nature of Mattermost requires from businesses technical expertise to handle installation, infrastructure management, updates, and maintenance by themselves. For small businesses without dedicated IT resources, this setup process can be a significant barrier. Additionally, Mattermost has a smaller integration marketplace, which may limit connectivity with certain third-party applications. The cloud-hosted version of Mattermost also tends to be less competitively priced for small teams, reducing its appeal for startups looking for affordable SaaS solutions. Finally, while the desktop experience is solid, the mobile app is often considered less polished than those of more commercially focused platforms.

Best for:

Mattermost is best suited for organizations that require high security, data sovereignty, and customization, such as technology companies, government institutions, and enterprises operating in regulated industries.
