The collection round
The Collect tab is the round in one list: what is still owed this period, worst first, with the arrears from earlier periods above it.
What the tab shows
At the top is the period and the amount still Outstanding, with Arrears from earlier periods shown beneath it when there are any. A bar shows how much of what was billed has been collected, and Read a slip sits alongside.
