While it is possible to implement Salesforce independently, it can be challenging without prior experience or technical expertise.
If you are entirely new to Salesforce, we do not recommend doing this by yourself.
While this option may seem tempting with the out-of-the-box admin-friendly back-end interface that Salesforce offers, you run the risk of implementing a solution that may work for today but is not done in a scalable way.
Then, when your business grows, you have to rebuild existing functionality, which can result in other components not working. It is known as
technical debt, and recovering or removing technical debt is a common request for implementers seeking out consultancies.
