Prioritize collections from an accounts receivable aging report

Review the accounts receivable aging below and turn it into a collections plan for {{period}}, for {{collector}} to work from. The goal is to bring in the most cash with the least damage to good customer relationships, so the plan should put effort where the money and the risk are.

Aging report (customer, invoice, invoice date, due date, amount, days past due):
"""
{{aging_report}}
"""

What we know about each customer's payment history, disputes and promises to pay:
"""
{{customer_notes}}
"""

Our credit and collections policy (reminder steps, when to hold credit or charge late fees, who approves write-offs):
"""
{{policy}}
"""

Today's date: {{today}}

Produce:
1. Summary: total outstanding, and the amount and share in each bucket (current, 1 to 30, 31 to 60, 61 to 90, over 90 days past due), plus a "Check the data" line for invoices that cannot be placed, so the shares add up to 100%. Show each share as a calculation, for example "12,400 / 86,000 = 14.4%".
2. Chase first: up to 10 customers, with the columns Customer, Amount overdue, Oldest days past due, Why now, Next action, Owner (the collector, or the person our policy names for that step). Rank by amount overdue, moving older debt up, and state the ranking rule you used in one line. If a customer has both disputed and undisputed invoices, chase the undisputed ones and mention the dispute under Why now.
3. Disputes and blockers: invoices held up by a dispute, a missing purchase order or wrong billing details, with what is needed to clear each. Keep these invoices out of the chase list, because chasing a disputed invoice as unpaid usually slows payment down.
4. Policy steps due: customers who have reached a step in our policy, such as a final notice or a credit hold, quoting the step. Where that step would hit a customer with a good record, show the record beside it and leave the call to the approver.
5. Write-off candidates, with the facts only, for the approver named in our policy to decide.

Rules:
- Use only the figures in the report. Recalculate every total and say if the report's own totals do not match.
- Do not recommend legal action, collection agencies or credit holds beyond what our policy says.
- Do not invent payment promises or contact history.

Keep the text outside the tables under 250 words. If an invoice is missing a due date or amount, put it in the "Check the data" line instead of placing it in a bucket.
