When looking for software there are two options Off-the-shelf and Bespoke Software, below are some of the pros and cons for both. 

Off-the-shelf 

Pros

• Cheaper than bespoke because the development costs are spread across a large number of users.
• The development work has already been done, so all you need to do is set up the software and start using it.
• If it is a commonly used package, users may already be familiar with it, saving on learning time and training costs.
• Off-the-shelf software often has more functionality, because the developers try to meet the requirements of as many users as possible.

Cons

• You may have to compromise on your requirements as it is not build exactly to how your business works.
• The software may include functionality that you don’t need, as it is trying to meet the different requirements of a number of users. 
• The vendor’s plans for the future may not always fit with your own. As a single customer amongst many, you may not be able to get the features you want implemented.

Bespoke

Pros

• Tailored to your business.
• The software will evolve over time with your business.
• No per user costs, as your business grows your user costs wont. 
• Your competitors will not have the same software giving you a competitive edge. 

Cons

• Higher set up costs
• Takes long to set up
