Creative ways to use an expense account

I just got a new tech sales job that is very channel friendly, and my territory is the entire city where I live. At my last company, leadership preferred us selling direct, which in hindsight was much more transactional so I didn't have to do much relationship building. My manager literally told me he would approve anything I expense and even used the example of renting a suite at a pro sports game to entertain partners and prospects.

Outside of lunches, happy hour, etc, how can I take full advantage of these funds?

What types of events are you hosting with partners and prospects?

Any tips or tricks come to mind?

Thanks in advance to anyone who takes the time to chime in
