10 best business chat tools for free

Below are 10 business chat tools that facilitate smooth communication.
 
Chat tools allow for casual sharing of information to stimulate communication. However, due to the nature of chat tools, there is a problem with information flowing if the communication continues within the same talk room.

Anyone can easily leave information in “Note” of Stock and share it with any member. Also, since “Message” and “Task” are tied to the “Note”, the main feature of this tool is that you can communicate and manage tasks without mixing topics like other chat tools.

7 must-know selection points for business chat tools

Here are 7 points to consider when selecting a business chat tool. It is important to ensure that you select the following selection points in order to avoid mistake of implementing.

(1) Is it easy to use?

Select a tool with simple operability that all employees will find “easy to use”.
 
Especially in non-IT companies, there are often differences in IT literacy among employees. Therefore, if you introduce a tool with complicated operations, employees will easily become resistant to it, and it will not spread throughout the company.
 
Therefore, introducing a tool in which each action can be performed with a few simple operations and the content is easy to read will facilitate information management and sharing. Specifically, the best tools are those with features such as “easy to send messages,” “notification settings,” and “save received messages & make them into tasks”.

(2) Is the security robust?

The robustness of security is also an important indicator when selecting a chat tool.
 
Different business chat tools have different levels of security and permission setting functions. Also, the level of security and the flexibility of permissions that can be set vary depending on the plan, so it is necessary to consider whether the tool meets your company’s security policy as a criterion.
 
If the tool allows administrators to easily manage access privileges, they can immediately suspend access privileges in the event that an employee loses or misplaces a device, preventing information leaks.

(3) Does the cost match your company?

Another important point is the cost of the tool when it is introduced and when it is operated.
 
The cost of a tool varies depending on the tool and plan, including the initial cost, monthly usage fees, and optional features. Therefore, it is advisable to calculate the costs based on your actual image of what functions are necessary and the number of users.
 
Also, be aware that if the tool is cumbersome to set up before you actually start using it, or if you have to provide training to your employees before they can use it, it will cost you more time and effort than necessary to introduce the tool.
 
Many tools offer free plans or trial periods, so consider whether to implement the tool after trying it out for free in relation to your budget.

(4) Is it over- or under-functional?

Make sure that the tool you are considering is not excess or insufficiency functions.
 
Business chat tools generally have multiple functions, such as voice/video calling and file sharing, in addition to chat functionality. However, even if the tool is suitable for your company’s internal environment, there may be cases where you actually try using it and find that you do not use many of the functions
 
Therefore, it is necessary to clarify the purpose of using a chat tool, such as “to activate communication through the chat function,” before considering its introduction.
 
In addition, in many cases, the more multifunctional the tool is, the higher the price is set. So, a tool like Stock, which is equipped with functions that are not excess or insufficiency for information sharing, can reduce both fees and training costs.

(5) Does it support multiple devices?

Make sure that the tool is multi-device compatible.
 
If you can use the tool on your smartphone or tablet, you can easily communicate even when you are not in the office, such as when you are out of the office or working remotely.
 
Also, even if you are out of the office, you can check shared information with a single device at hand, preventing information sharing lags and omissions. Furthermore, it is more convenient if the system can be used on any OS, not to mention iPhone and Android devices.

(6) Is there support?

It is also necessary to confirm that there is a full support system in case of any problems or failures.
 
If the support desk is only available in free plan or nothing, you will not be able to receive sufficient support.
 
Also, if a tool only provides chat support, it may take more time to communicate with the supporter than telephone support, and you may not be able to solve the problem.
 
Be sure to check the availability of satisfactory support to ensure continuous operation of the tool.

(7) Can the tool be integrated with other tools?

It is also important to check if the tool can be integrated with other tools in your company.
 
If you can integrate with other tools, you can easily synchronize information when introducing a new chat tool, and you can save training costs.
 
Also, some tools can be linked with APIs to allow users to log in and operate from other tools, and notifications from other tools can be sent to the chat room. Therefore, if there are tools already in use within your company, you are required to check their compatibility as well.

Summary of 10 best free business chat tools

We have focused on 10 business chat tools and how to choose one.
 
Compared to e-mail, chat tools allow easy communication since there is no need to set up greetings, cc, and bcc. Also, since it is easy to communicate with multiple people, it can be used for “intra-departmental or team meetings”, “sharing project information or customer information”, and so on.

However, a complicated tool will not penetrate the entire company, so the best solution is a business chat tool like Stock introduced here, which can be used immediately even by employees in non-IT companies, and store information without information flow.
