The beauty of modern ERP packages is that you have options to choose from during your ERP software selection. You can either deploy a solution by hosting it internally on your own servers (“traditional ERP”) or perhaps you would rather not deal with the software and have it hosted somewhere else (“Software As A Service” or “SaaS”). As part of your ERP selection process, however, you should be aware of five key variables that will ultimately factor into the decision that is right for you.

Five Key Differentiators Between SaaS and Traditional ERP Software Packages

  1. Simplicity. In general, SaaS is simpler to deploy from a technical perspective. Because you don’t need to purchase additional servers or physically install the software for yourself, it can be an easy and quick means of deploying the software. On the other hand, the high level of technical ease may create additional business complexities that you may not otherwise experience with traditional ERP (see #2 below).
  2. Flexibility. Because traditional ERP is installed on your servers and you actually own the software, you can do with it as you please. You may decide to customize it, integrate it with other software, etc. Although any ERP software will allow you to configure and set-up the software the way you would like, SaaS is generally less flexible than traditional ERP in that you can’t completely customize or rewrite the software. Conversely, since SaaS can’t be customized, it reduces some of the technical difficulties associated with changing the software.
  3. Control. Because of #2 above, many companies find that they don’t have control over SaaS software as they would like, relative to traditional ERP. This is especially true of mid-size or large companies with well-defined business processes that are not able to be changed to fit the software. Smaller companies generally are able to adapt their business processes to the software easier than a larger organization.
  4. Accessibility. Since SaaS is entirely accessed through the web, you are in a world of hurt of the internet goes down. Alternatively, traditional ERP does not require internet reliability, provided your users are accessing the software from inside your company’s network.
  5. Cost. In general, SaaS can be deployed at a much smaller initial cost, which can be attractive to smaller businesses. However, the ongoing annual payment can be higher for SaaS because you’re paying to use the software. Much like leasing vs. buying a car, that payment never goes away as long as you’re using the software and can become costly as you grow and add employees to the system.

Clearly, there are tradeoffs between the two options. The above five factors should be thoroughly prioritized and evaluated as part of any effective ERP software selection project.
