The checklist

Each open line has its button on the right; lines with a green tick are done.
When nothing is left it says so, and you can close the month. Use Check again after fixing something. A month that is already closed shows the checklist as it was at the close.
Not sure where to start? Choose Ask Jacinta: she takes you through what is left one item at a time, in plain words.
Done for you at month end
Money in other currencies, owed to you or by you, and held in foreign-currency bank and cash accounts, is revalued at the month-end rate automatically, so your balance sheet shows what it is worth today.See also
