Good afternoon, Moira.
Congrats on your new CRM implementation! I'm not sure if there is one definition for internal comprehensive donor count that is used across the board by institutions. It depends on what questions you are trying to answer. VSE has its' own reasons for how it counts donors that is largely guided by a desire to maintain the integrity of their data and ensure that their users know they are comparing apples to apples for benchmarking.
I think that, in general, if you are wanting a total number of donors to report externally, most probably would include spouses. However, in your context, you mention internally. If so, I would start with what questions you are trying to answer. If you are counting donors to assess alumni participation, definitely you would want to include both spouses since a number of your households are going to have two alums. If you are counting donors to assess things like donor retention, acquisition, re-activation, or similar, it might make sense to count only households.
Many newer CRMs now include a type of credit called "recognition credit" that is geared towards solving this issue. In that context, recognition credit is given to both the hard credit and soft credit donors on a transaction. In those cases, soft credit is then limited to scenarios where you receive a gift from an organization that you want to link to an individual. If your new CRM has the capability to generate and store recognition credit, I would encourage you to leverage it.
Best to you and your new CRM,
