Microsoft Office® 365 and Microsoft Office 2013, while very similar in functionality, still have a few differences. Knowing the differences will help in deciding which is better for you and your staff.
First and foremost, Office 2013, once purchased, is yours to keep because you own it. Office 365, on the other hand, is subscription-based which means you pay a monthly or annual subscription fee for its use. So, depending on what you are using it for, having this flexibility may be useful.
Another key difference is Office 2013 packages can only be installed on one computer, while Office 365 can be used on up to five PCs/Macs or more depending on the product you purchase.
Office 2013 products can be purchased in the typical bundles, such as Home Office & Student, Office Professional 2013, etc., or as one-offs as well. When purchasing a subscription to Office 365, no matter if you want them or not, you get the whole suite of products including Word, Excel®, PowerPoint®, OneNote®, Outlook®, Publisher®, Access®, SkyDrive®, and more depending on your subscription level.
Knowing these things in advanced can make your purchasing decision a lot easier. Once your decision is made, make sure to utilize your software purchase with easy-to-use online training from Atomic Training.
