A more thorough explanation:

The business-entry rule, also known as the business-records exception, is a legal concept that allows certain business records to be used as evidence in court. This includes reports, memos, and other documents that were created in the normal course of business.

For example, if a company keeps records of its sales transactions, those records could be used as evidence in a court case involving a dispute over those transactions. The business-entry rule allows these records to be admitted as evidence because they were created as part of the company's normal business operations.

However, there are some limitations to the business-entry rule. If there is reason to doubt the reliability of a particular record, such as if it was created in anticipation of litigation, it may not be admissible as evidence.

Overall, the business-entry rule is an important tool for businesses and individuals who need to use their records as evidence in legal proceedings.
