The sale of the company can be threatening for employees who fear being downsized. If you are always collecting documents you can be stealthier, instead of asking all departments for all documents on short notice, which can shake things up.

The sale of a company is often a long and complex negotiation, with many levers applied, fair or not. Opening yourself up to complaints from a buyer over incomplete or missing diligence items can cost a seller needlessly in deal points or even a reduced purhase price.
