Set it up once, and it runs itself
Setup is six short steps: dates, which decisions open in which quarter, the starting accounting methods, co-instructors, and whether to add the evaluation stage.
Each quarter then closes on its own at its deadline. Results are calculated, the next quarter opens, and a team that didn't submit keeps last quarter's decisions. Your pages show who has submitted, what's waiting for you, and every firm's statements side by side, with a spreadsheet download for your own analysis.
The point for your course
You spend class time on the statements, not on running software.
