Lump sums are typically associated with large payments of money that are made at once, such as a salary bonus or an inheritance. However, there are a variety of synonyms for the term "lump sum" that can also be used to refer to large payments or sums of money. These include terms such as "one-time payment," "single payment," "bulk payment," "fixed sum," and "total payment." Each of these terms conveys the same idea as a lump sum, but may also be more specific in terms of the type of payment that is being referred to. Whatever term is used, the idea of a large, one-time payment is the same.
