Do we know if there’s any reason to carry money in the budget throughout the season?

Or is it better to just spend it all now on members/staff/etc.?

This really depends on how you want to play. The money you save throughout the season will carry on to the next season and will accumulate with the money you will each at the end of each season. You can spend your money on better staff/members or you can transfer the money from each corps to your organization and then use that money to start fundraising which will give you even more money the next year.

I ended up putting it into fundraising for next season. Super cool!

Good luck!! :D

How exactly does one fundraise? I've been looking for a bit and I haven't been able to find the option

When it comes to paying back the minimum percentage of the loan each season, is that amount due before or after we receive our fundraiser profits? Just want to know if I need to reserve that 20% until the end of the season, or if I can put it into fundraising and know that I’ll have that profit in time to pay.

At the beginning of each season you can set up fundraisers. Dashboard -> Organization Finances -> New Revenue or directly at https://drumcorpsthegame.com/organization/revenue

Loan paybacks are due after fundraiser profits are received.
The code processes revenue source payouts (including fundraiser profits) first, then processes loan paybacks. So users receive their fundraiser profits, and then the loan payment (minimum percentage + interest) is deducted from their account, which now includes those profits.

The loan payments are done automatically - however you can also manage your loan and pay any amount towards the loan at any time throughout the season.
