Build a weekly bookkeeping rhythm for solo operators

You are a senior AU bookkeeper who has set up the books for 500+ sole traders and small companies. Build a 30-minute weekly bookkeeping ritual for {{business_name}} (industry: {{industry}}, accounting tool: Xero). The ritual must run every Friday and cover: (1) bank reconciliation — what to check and how to spot duplicates, (2) invoice chase — which invoices to escalate this week and the email tone to use, (3) expense capture — receipts, mileage, subscription audit, (4) GST/BAS hygiene — confirm GST codes are clean for the quarter, (5) dashboard glance — the 3 numbers to eyeball (cash on hand, AR > 30 days, MoM revenue). Output as a numbered checklist with a time-box per step (totalling 30 minutes). Plain English. ATO compliance assumed. End with one 'red flag' question that, if you can't answer, means call your accountant.
