募款 is a verb-object separable compound (离合词) meaning 'to raise funds' or 'to collect donations'. It is commonly used in the context of charity, disaster relief, or fundraising events. When you need to add a duration, a measure word, or a complement, the verb 募 and the noun 款 can separate: 募了款 ('raised money'), 募过款 ('have raised money before'), 募到款 ('managed to raise funds'). The object of the fundraising is typically introduced with 为 or 给 before the verb.
