Communication Tools for Business, by Category

Communication tools are the software and apps teams use to share information, both with each other and with customers. Common examples include business phone systems, video conferencing, team messaging and SMS, email, contact center software, and AI agents that handle customer conversations.

Most businesses use several of these at once. As teams grow, many move from separate apps to a communication platform that brings several of these channels together in one system. The challenge is choosing tools that work together, so conversations, context, and customer details don't end up scattered across apps. This guide covers the main types of communication tools, the features worth evaluating, and examples by category.

What are communication tools?

Communication tools are software that helps people exchange information at work across channels like phone calls, video meetings, messaging, SMS, and email. They support two kinds of communication: internal, between employees and teams, and external, with customers, prospects, and partners.

Examples of communication tools include:

• Business phone systems for calling, voicemail, and call routing

• Video conferencing for meetings and screen sharing

• Team messaging and business texting for quick conversations

• Email for longer, asynchronous communication

• Contact center software for customer-facing teams

• AI agents that answer and resolve routine customer conversations

• Collaboration tools like project management, productivity suites, CRMs, and file sharing that keep work and customer information connected

Communication tools vs. communication platforms

A communication tool is a single app built for one job, like a video conferencing app or a team messaging app. A communication platform brings several channels together in one system, typically calling, video meetings, messaging, and SMS, with shared admin settings and customer data. Some platforms also include contact center software and AI agents.

Examples of communication platforms include:

• Unified communications platforms, also called UCaaS, which combine business calling, video meetings, and messaging for internal and external communication

• Contact center platforms, also called CCaaS, for customer-facing teams that handle high volumes of calls and digital conversations

• Internal communication platforms, like company intranets and employee apps, for announcements and company-wide updates

• Customer communication platforms that manage customer conversations across channels like SMS, chat, and social messaging, often grouped with customer engagement software

• Communications platforms as a service (CPaaS), which give developers APIs to add calling and messaging to their own apps

Many businesses start with individual tools and move to a platform as they grow. One platform can mean fewer apps to manage and fewer places for customer context to get lost.

Internal vs. external communication tools

Internal communication tools

Internal communication tools help employees work together across locations, devices, and teams. Most teams rely on messaging for quick questions, video meetings for discussions, and phone calls for conversations that need more nuance.

Tools that transcribe and summarize meetings can help too. People can focus on the conversation instead of taking notes, and colleagues who missed the meeting can catch up from the transcript or recap.

External communication tools

External communication tools shape the customer experience. Sales teams reach prospects by phone, SMS, and video, while support teams need call routing, call transfer, and contact center software to get customers to the right person quickly.

More businesses are also using AI agents to answer routine customer questions at any hour and hand complex ones to people with the full context. When internal and external tools run on the same platform, teams can share the full picture of each customer conversation, which can make it easier to understand what customers want and act on it.

Key features to evaluate in business communication tools

Whether you're replacing one tool or rethinking your whole stack, look for:

• Calling, SMS, and video in one app. A unified communications solution that combines phone calls, business texting, team messaging, and video meetings means employees aren't switching between apps, and IT isn't managing several vendors.

• Support for internal and external communication. The same tools can work for team conversations and customer conversations, so context can carry over between them.

• Admin controls that scale. Admins should be able to add users, manage phone numbers, and change settings themselves, without waiting on a support ticket.

• AI features included. Check whether AI transcription, call and meeting summaries, and other AI features are part of the plan or sold as add-ons.

• Integrations. Look for integrations with the CRM, help desk, and productivity tools your teams already use.

• Security and compliance. Ask about encryption in transit and at rest, role-based access controls, and compliance documentation like SOC 2, HIPAA, and GDPR.

• Reliable support. Find out what support hours and channels are available, especially if your teams work across time zones.

• Desktop, mobile, and browser access. Employees should be able to use the same tools from any device.

Communication tools for enterprise teams

At enterprise scale, the same criteria apply, but the stakes are higher. Large organizations typically need centralized administration across offices and countries, governance over who can access recordings and customer data, compliance documentation for regulated industries, and consistent call quality for global teams.

Many enterprises are also evaluating AI agents for customer conversations, which raises questions about what data those agents can access and how they hand conversations to people. An enterprise communication solution that brings calling, meetings, messaging, contact center, and AI agents onto one platform can simplify these decisions, since security settings, governance, and analytics live in one place.

Communication tools by category

These examples are grouped by what they help teams do. Many businesses use one tool from each category and connect them through integrations.

All-in-one communications: Dialpad

Dialpad brings calling, video meetings, SMS, team messaging, contact center, and AI agents together on one platform, available on desktop, mobile, and web browsers.

Dialpad Connect covers business calling, meetings, and messaging, with AI transcription and AI Recaps included in every plan. Dialpad Support for contact centers adds tools for customer-facing teams, and Dialpad Resolve, AI agents for voice and digital interactions, can answer and resolve routine customer conversations. Dialpad also connects with many of the tools below through the Dialpad Partner Marketplace.

Project management: Asana and Trello

Project management tools like Asana and Trello help teams track tasks, deadlines, and ownership with lists and boards, which can reduce the number of status-update messages and meetings.

Productivity suites: Google Workspace and Microsoft 365

Google Workspace and Microsoft 365 combine email, calendars, documents, and file storage, and most businesses standardize on one of them. Dialpad integrates with Google Workspace and Microsoft Teams, so employees can call, message, and meet alongside their email and calendar.

CRM and customer support: Salesforce, HubSpot, and Zendesk

CRMs like Salesforce and HubSpot track customer relationships and sales activity, and help desks like Zendesk manage support tickets. Connecting them to your communication tools means calls and messages can be logged to customer records without manual entry. Dialpad integrates with Salesforce, HubSpot, and Zendesk.

File sharing: Dropbox, Google Drive, and OneDrive

File sharing tools store documents in the cloud so teams can share and edit them from any device. Google Drive and OneDrive usually come with their productivity suites, while Dropbox works alongside either.

How many communication tools does your team need?

Start with the channels your teams use every day and whether they talk mainly with each other, with customers, or both. Most businesses need at least a unified communications solution for calling, video, and messaging, plus the collaboration and customer tools that fit their workflows. Contact center software and AI agents can be added as customer-facing needs grow.

Every app that holds part of a customer conversation is one more place context can get lost. Dialpad's AI platform for customer experience keeps calls, meetings, messages, contact center, and AI agent conversations in one place, so teams can turn those interactions into operational insight.
