Decide which bills to pay first when cash is short

Help me plan which bills to pay with the cash available, for {{payer}} to approve before any payment goes out. The goal is to keep the business running and avoid the costliest consequences, while being honest with suppliers we cannot pay yet.

Cash available to pay bills now: {{cash_available}}
Today's date, and the date of the next payment run: {{dates}}
Money expected in before the next payment run, with dates, and whether each is certain: {{expected_receipts}}

Bills due or overdue (supplier, amount, due date, what it is for, late fees or interest, what happens if it is late):
"""
{{bills}}
"""

Priorities I have set: {{priorities}}

Unless my priorities say otherwise, order the bills by the consequences I have described: payroll and payroll taxes first, then bills whose non-payment would stop us operating, then bills with penalties, then the rest. Within a group, earlier due dates come first.

Produce:
1. Pay now: a table with the columns Supplier, Amount, Due date, Why it comes first, Running total. The running total must not go over the cash available: if a bill does not fit, skip it, say so, and continue down the list. Do not propose part payments unless I have said the supplier accepts them.
2. Pay at the next run: what can wait and until when, counting only receipts I marked as certain, and what changes if the others arrive.
3. Contact before the due date: suppliers to ask for a delay or part payment, each with a one-line point to make, for example "Offer half now and the rest by the 20th."
4. Check: cash available minus total paid now, shown as a calculation.

Rules:
- Use only the amounts, dates and consequences I have given. Do not assume a supplier will accept a delay or waive a fee.
- Do not suggest borrowing, using money set aside for taxes, or skipping tax payments. If cash does not cover payroll and payroll taxes, say so at the top and suggest I speak to my accountant or bank today.

Keep it under 350 words outside the tables. If a bill has no due date, or I have not said what happens if it is late, put it in a "Need to know" list rather than ranking it.
