What is online fax?

Another great benefit is numerous advantages and can be found within different online fax service providers. This is the list that contains some of the most needed features and most interesting ones:

Automatic call recording – This feature will help you save unlimited minutes of phone calls. How many times have you forgotten some important tasks or requests from your clients? You do not have to take notes anymore, now you can just play the recorded call and be on track with your tasks. Also, you can protect yourself and your employees by saving phone calls in case you get a customer complaint. 

Administrator protection – You can oversee everything that is happening on an online cloud service. You can also choose if you want to add somebody else to the role. This way you can see the access to the platform, changes made, give, or close the access to a specific person. 

Optimized CRM – Providers usually offer integrations with Office 365, Salesforce, G Suite, and many more to help you organize internal and external communication. This feature will save you time and allow you to be more effective on an everyday basis and stay up to date with the market and requests from existing and new clients.

Storage – Well, like every cloud-based service you can choose between several different options. If you want to have unlimited storage for your documents, you will have to choose a plan that will cost you more. If you are satisfied with the offered storage possibilities within the basic plan it is a good option. Basic plans also have suitable storage options that will satisfy your business requirements. 

Accessibility – It is important to pay attention to the features that give you better access and mobility. To be able to send your faxes faster you need to have the option to edit and sign the document electronically. Of course, you can always print, sign manually, and send it. But now it is much faster, cheaper, and convenient to do all the tasks with just one click. 

Mobile app – Together with the editing feature, you should also look for providers that offer a mobile app. This way you can send, receive, and operate anywhere and anytime if you have an internet connection. 

Confidentiality – No matter what type of business you have it is always welcomed to have high-end confidentiality. An encrypted connection is a must when talking about business correspondence because you are sending private information like bank accounts, names, addresses, etc. In some other industries, like medical companies, it is recommended to look for providers specialized in this industry because you will also get important compliances to be in accordance with the law in your or your client’s country. 

Trial period – Companies that value their clients, their time and money, will always offer a free trial period. Of course, you want to know if the service suits your business needs. Sometimes these trial periods can include some comprehensive offer with advanced features, the more the better. Remember that the trial period is limited and that you should explore all the options offered before purchasing the online fax service.

Transparent policy – Make sure that you always check the policies of the company, their customer support, and compliances. This is not a detective job, you just need to see if they have it all on their official website, to see if the company has some certificates, affiliates, and compliances. You can also check the reviews on their customer support and see if they are available through email, live chat, or some other option.
