Make a 13-week cash forecast to get through the quiet months

Help me build a 13-week cash forecast.

My business: [what you do and when it's quiet]
Bank balance today: [amount]
Expected money in by week: [sales, invoices due, or a weekly average]
Regular money out: [wages, rent, suppliers, drawings, loans]
Big one-off payments coming: [VAT, tax, insurance, annual software]
How reliably customers pay: [e.g. most pay late by 2 weeks]

First ask me up to 5 short questions. Wait for my answers.

Then:
1. A 13-week table: week, opening balance, in, out, closing balance.
2. The tightest weeks highlighted, and why.
3. Actions ranked by effect: chase invoices, move a payment date, a quiet-season offer, delay a purchase.
4. A Google Sheets layout with formulas so I can update it in 10 minutes each Monday.
5. A trigger point for talking to my bank or accountant.

Use my figures only; show the sums. Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or figures. UK English.
