Defaqto Engage is a research and financial planning suite for advisers, and its switching modules answer a narrow question with a lot riding on it: how does moving compare with staying put once every charge is counted? Advisers and paraplanners build that case inside the system. They enter what the client holds today, research a replacement and compare the two on cost. The same working is what a file checker needs, because the comparison, the alternatives considered and the option of leaving things as they are all end up in the report.
