Produce a period summary a founder or bookkeeper can act on: cash in vs out, top merchants, unpaid invoices, overdue bills, pending expenses and open data-quality issues. Use when a user asks "how did we do this month", "month end", "period summary", "cash in and out", "what's unpaid", "what's overdue", "expense claims pending", or wants a weekly/monthly finance briefing from Dynt.
