When we start implementing an ERP system then what should be the first point to start?

 Make a team to examine and current system and potential benefits and set objective and develop a project plan and make sure that the objectives are done perfectly

One of the main reason you'd invest in an ERP system is to make it easier for you to do your business and track or monitor your transactions in any given point of time. Since no company are the same, the first thing you'd want to do is gather the requirements in accordance to the flow or cycle of your business, and work out the solutions with your software consultant so that an ERP software that best suit your business requirement can be established.

ERP implementation should start from Requirement gathering.

The team is then trained and trained and set goals.
