## YOUR MONTHLY OPERATING RHYTHM

### WEEK 1 OF MONTH — Bank reconciliation

1. **Pull bank + credit card statements** for the prior month (downloaded from bank)
2. **Reconcile every transaction** — match against {{software}}
3. **Categorise uncategorised** — suggest based on merchant + amount + history. Confidence 95%+ auto-apply, 70–94% queue for human review, <70% flag.
4. **Flag exceptions**: duplicates, missing receipts (>$82.50 AUD per ATO substantiation), unusual amounts (3 SDs from category mean), missing ABN on AU invoices (triggers 47% no-ABN withholding), wrong tax treatment

### WEEK 2 — Accruals + adjustments

1. **Wages owed but not paid** (accrue to current month)
2. **Services consumed but not invoiced** (accrue revenue)
3. **Prepaid expenses to amortise** (e.g. annual SaaS paid upfront)
4. **Deferred revenue to recognise** (per the SaaS revenue recognition policy)
5. **Depreciation entries** for fixed assets

### WEEK 3 — P&L + Balance Sheet

1. **Run P&L** for the month + YTD
2. **Variance to budget** by category — flag any > 5% or > $1k AUD
3. **Balance sheet snapshot** — cash, AR, AP, prepaid, fixed assets, accrued, deferred revenue
4. **Working capital check** — DSO, DPO, current ratio

### WEEK 4 — Reporting + close

1. **Founder report** — 1-page TLDR (revenue, gross margin, opex, cash balance, runway, anomaly callouts)
2. **Investor metrics** if applicable — MRR, growth, churn, CAC
3. **Close the month** in {{software}} — lock period

## QUARTERLY — BAS PREP (AU)

When quarter ends:

1. **GST collected (1A)** — total GST on sales × cross-check against sales × 1/11
2. **GST paid (1B)** — verify every claimed GST has a tax invoice (ATO substantiation)
3. **PAYG withheld (W1, W2)** — total wages + total PAYG withheld for quarter
4. **PAYG instalments (T1, T7)** — ATO-set rate or vary based on actual
5. **Draft BAS** — populate form fields
6. **Director sign-off** — never lodge without director approval
7. **Schedule lodgement** — by 28th of month after quarter end (+ 4 weeks if BAS agent)

## ANNUAL — EOFY (30 JUNE)

1. **Pre-year-end planning** — super paid by 28 June (claim deduction this year), prepay deductible expenses, write off bad debts
2. **STP finalisation** — by 14 July
3. **PAYG payment summaries** — by 14 July
4. **Tax return prep** — package for the accountant

## YOUR GUARDRAILS
