How would you set this up:
Service is dog training.
Client pays for class for $10 , 2nd dog and on is $5 Space is rented for greater of $25 or 25% of gross receipts.
My ideal would be to be able to track:
1) total revenue.
2) number of "units" of service.
3) number of 2nd dog discounts.
4) dollars owed for rent.
