Software as a service (SAAS) is a business model where the software is hosted and managed by the vendor. The customer pays a monthly fee for the right to use the software, instead of buying it outright.

This model has been around for some time, but has recently been adopted by many companies who offer software as a service. There are many advantages to this model, and the benefits far outweigh the disadvantages.

What is SAAS?

SAAS refers to a business model where the vendor hosts the software, and the customer pays a monthly fee for access to the software. The customer does not own the software, but rather pays for access to the software, as well as any updates that may be made to the software.

This model is popular in the field of software development, and has been used for many years to develop applications for clients. This model has also been used to create websites, which can be accessed through a web browser.

The advantages of using software as a service over buying the software outright include:

1. Less investment needed to get started. When you purchase software outright, you must pay for the software, as well as the installation of the software on your computer. With software as a service, you only need to pay for the software once, and then you can use the software indefinitely.
2. Easier to update. Since the software is hosted by the vendor, you can easily update the software at any time. In addition, you can often receive upgrades for free, if they are available.
3. No capital outlay. You do not need to invest money in order to start using software as a service. Instead, you simply pay a monthly fee for access to all the features of the software.
4. More flexible. Since you are not purchasing the software outright, you have more flexibility with how you use the software. For example, you can use the software in a way that is most appropriate for your company.
5. Better security. Since you are not the owner of the software, you cannot accidentally delete or corrupt files. This means that you have better security, since there is no chance of data loss.
6. Improved productivity. Since the software is hosted, it can be accessed from anywhere, anytime. This means that you can work on the software at any time, regardless of where you are.
   
7. Reduced costs. Since you are paying a monthly fee for access to software, you can reduce the amount of money you spend on software. In addition, you will not need to hire additional employees to install and maintain the software.

The disadvantages of using software as a service include:

1. Requires a monthly payment. When you purchase software outright you can pay a one-time fee, and then you can use it for an indefinite period of time. With software as a service however, you must pay a monthly fee.
2. Limited support. When you purchase the software outright, you can contact the vendor for support. However, when you use software as a service, you are likely to have to contact the vendor directly.
3. Additional fees. If you want to upgrade the software, you may need to pay an additional fee.
   
4. Unreliable. Since the software is hosted on the vendor’s servers, it can become unreliable. In addition, the vendor may discontinue the service at any time.
