Legacy system has multiple representations of organizations and we need to merge them

Our customer owns several old applications. Each of them has tables to represents organizations, tables named like : “Customer”, “Supplier”, “Member”, “Dealer”, etc. I count about twenty of them. It poses a lot of problems for accounting, reporting, and basic consistency. We would like to merge all these this legacy tables in one table, with one service exposing them. What are the best practices for this matter ?
