This keeps your total cost of ownership low while giving you an agile system to meet customer needs.

Additionally, our forum software seamlessly integrates with our industry-leading ticketing system, so agents can quickly escalate forum posts to support tickets when complicated issues arise.

Community software can allow your customers to get quick answers to their questions, share information, and engage with other users. But that's not all. Here are some specific benefits forum software can have for your business:

• Increases customer engagement: Through gamification features like badges and voting, forum software makes engaging in your community fun and rewarding. People who successfully answer questions earn points for doing so and, in some cases, may acquire greater permission levels as their score increases.
• Provides clearer insights about customer needs: Customers talk to each other on forums about what works and what doesn’t, providing a distinct user perspective. By facilitating genuine conversations about your company, product, and service, forums create a new, unique source of customer feedback for your organization to mine for insights.
• Reduces support costs: An online community turns other users into a self-service resource. This reduces ticket volume by increasing ticket deflections, keeping support costs down, and freeing up your service agents’ time.
• Enables 24/7 support: If your current customer support channels rely on live agents working regular business hours, there may be times when your customers feel left in the dark. By implementing forum software, you’ll automatically provide customers with a self-service solution they can access 24/7.
• Creates more sales opportunities: Customers can organically learn about products from other customers they’d otherwise be unaware of. A service agent can also respond directly to a customer support thread to inform customers of a new or upgraded product that can help solve their problem.

When shopping around for the best forum software for your business, prioritize these five essential features.

• Integrated escalations: Help desk software integrations enable service agents to escalate a community post to a support ticket to continue the conversation when complex issues arise. In short, integrated ticket escalations within community forum software can enhance the customer experience by ensuring community members have a seamless way to receive support.
• Community moderators and moderator groups: Community moderator capabilities empower moderator groups to track questions, bring in support agents, and remove unruly users.
• Unified search: Users can easily search the contents of your entire forum to quickly find the information they are looking for, whether it is an answer to a question or an existing thread they want to comment on.
• Public and private options: Public forums allow for open discussions that anyone can participate in, attracting new members and promoting brand awareness. Meanwhile, private forums require members to log in to view and participate in exclusive discussions and track conversations that interest them.
• AI-powered spam protection: Whether flagging and removing malicious content or automatically detecting phishing attempts, AI-powered spam protection can keep a watchful eye over your community 24/7—ensuring your customers stay safe and saving your moderators time.

Selecting the right forum software may seem like an overwhelming process. Fortunately, keeping the following considerations in mind can help you choose the best forum software for growing a thriving online community for your business.

• Ensure the tool has adequate security features: Choose community software that follows cybersecurity best practices and industry standards to ensure the security and privacy of your business and customers. Better yet, picking software from a provider that meets global security and privacy compliance standards, like Zendesk, can help give you and your customers adequate protection and peace of mind.
• Assess the total cost of ownership: Forum software may be available with no licensing costs, but that doesn’t mean forum hosting is free. Deploying and hosting open-source software may require outside help, which will come at an additional cost. Plus, many forums don’t include integrated ticketing systems, which can increase expenses if you need to link threads to tickets. Consider what it might cost to license, configure, and maintain the forum software when weighing your options.
• Verify it has a fast time to value: The quicker you can get your forum up and running for your employees and customers, the better their experience will be. Zendesk gives you everything you need to set up your community forum right out of the box. That way, you can spend more time helping your customers and less time configuring tricky software.
• Look for a solution with a user-friendly interface: No matter what features a forum software offers, it won’t make an impact if your employees and customers don’t know how to use it. Because of this, you’ll want to prioritize a forum software with a user-friendly interface to host your branded support community.

Finding a solution that balances these criteria will help you get the most value out of your forum.
