Grant-issuing bodies impose a number of restrictions and reporting requirements on nonprofits, including which programs or activities may receive the funding, what geographical region it must be used in, and in which financial year each installment should be spent.
The UK Fundraising Regulator, for example, requires that you must use all funds raised for a particular cause for that exact cause. You must make sure that donations are used to support the project in line with any conditions attached to the donation. And you must keep a record of contributions given for specific purposes to make sure that you stick to the conditions of the donation.
There are also conditions relating to a certain defined measure of success, the amount of allowable indirect costs a grantee can charge to the donor (specified as an Indirect Cost Rate), and how different types of transactions and costs must be recorded. The complexity increases, for example, when multiple funders provide match funding, as it must be reported to all donors in full, even though it is only refunded in part by each donor.
