Considering data is the lifeblood of any non-profit/fundraising organization, seems very remiss at the basic level to not have a single position in charge of ensuring gifts are properly booked by IRS standards and that the basic data of your donors/potential donors is kept up-to-date and maintained.  I would approach from both the pro’s and con’s of this FTE clearly lining out the strategic importance of this work to the organization. In addition, bolstering the case with such facts as the number of gifts processed should give everyone a good idea of the need. The other option is to seek to outsource this need which will also bear a cost, mostly likely larger than bolstering the need with an FTE.  Lastly, describing how not hiring this FTE will have a negative impact on donor experience, should help advocate for this role.
