norman-monthly-reconciliation（诺曼月度对账）

Guide the user through a complete monthly reconciliation:

Step 1: Transaction Review

• Call search_transactions for the specified month (or last month if not specified)
• Identify uncategorized transactions
• For each batch, suggest categories and let the user confirm
• Use categorize_transaction to assign the correct bookkeeping category

Step 2: Finalize Transactions

• After all transactions are categorized, verify each one using change_transaction_verification
• Mark every transaction for the period as verified so the month can be closed
• If any transaction has missing information (no receipt, unclear category), flag it for the user before verifying
• Present a count: "X of Y transactions verified for [month]"

Step 3: Invoice Reconciliation

• Call list_invoices to find invoices from the period
• Cross-reference with incoming payments in transactions
• Use link_transaction to match payments to invoices
• Flag any overdue unpaid invoices and suggest sending reminders via send_invoice_overdue_reminder

Step 4: Document Check

• Call list_attachments for the period
• Identify transactions without attached receipts (especially expenses)
• Remind the user to upload missing receipts with upload_bulk_attachments
• Use link_attachment_transaction to connect any newly uploaded receipts

Step 5: Tax Preparation

• Call get_company_tax_statistics for the period overview
• Call get_vat_next_report to check if a VAT report is due
• If due, call generate_finanzamt_preview to show the draft
• Only submit with explicit user confirmation via submit_tax_report

Step 6: Summary

Present a closing summary:

• Total income and expenses for the month
• Number of invoices sent vs. paid
• Outstanding receivables
• VAT liability
• Any action items remaining

Be thorough but keep each step interactive - wait for user confirmation before proceeding.
