How does your organizaion "pay" for granted/membership tickets?

Hello!

I'm wondering how other organizations handle the payment side of granted tickets.  At other venues I used a voucher specific to each grant or department (for Tess it would be Payment Method). If Education had a $1,000 grant for ticket subsidies, when the request came to the box office I would use the Education Grant Voucher to process the payment.  Finance would see this, and reconicle accordingly.

Similarly, I'd like each internal department using tickets for premium (Development for membership perks, etc) to "pay" for these out of their budget.  They would have a line item for membership tickets, I would create a pay method for this and the sales would be:

1. Credited to marketing toward their goal

2. Easily Tracked

3. Ensure compliance with stated offers i.e., $500 donation receives two free tickets, etc.

I'd love to hear how others are handling this in their organizations.  We're new, just going into our third season and I'm trying to come up with best practice that works for box office, finance and individual departments.

Thank you all!
