Finance
Recognise dues across the year they cover.
Membership income earned over the term rather than banked on the day it arrives.

Dues collected in January are not January's income. The system holds that distinction so your accountant does not rebuild it in a spreadsheet.
Close a month that reconciles
Orders, refunds and adjustments reach the accounting view from the source the cart wrote. The numbers agree because they came from the same place.
