Summarise a Year of Freelance Income Into a Clear Financial Picture

Twelve months of invoices in a spreadsheet and no real sense of the shape of the year beyond the total. This works out the monthly average, spots the busiest and quietest stretches, names the client carrying the biggest share of income, and flags one risk worth watching, all without straying into tax advice.
