Cash Flow Planning for Melbourne Service Businesses — Staying Ahead of the Gaps

Why Melbourne Service Businesses Face Specific Cash Flow Risks

A Melbourne service business can be profitable on paper and still run out of cash. The service cash flow cycle is inherently gapped — you deliver work, then invoice, then wait for payment — but Melbourne adds specific pressures that make cash flow management more critical than in regional markets:

• Higher fixed overhead (rent, wages, insurance) means the cash required just to keep the doors open is greater
• Melbourne's corporate clients often expect 30-day terms, extending the collection cycle beyond what the business can sustain on its own working capital
• Melbourne's December/January period combines a busy invoicing month with slow payments and reduced January revenue — a dangerous combination without planning

The Melbourne Service Business Cash Flow Cycle

The cycle for a typical Melbourne service business:

• You quote (free)
• You win the job
• You deliver the work (cost incurred: Melbourne labour rates, materials)
• You invoice
• You wait — 7 days, 14 days, or 30+ days for Melbourne corporate clients
• You receive payment — weeks after the cost was incurred

Every gap in this cycle is working capital you're funding. In Melbourne, the cost of funding that gap is high — and the gap is typically larger than in regional markets.

Melbourne-Specific Cash Flow Traps

• December/January cash cliff: December is often a strong invoicing month, but corporate clients delay payment over the Christmas shutdown (settling in January/February). Meanwhile, January is Melbourne's quietest trading month. The result: low revenue in January combined with delayed December payments arriving in February.
• Corporate 30-day terms with 7-day supplier costs: Common for Melbourne businesses serving corporate clients. You're funding 23 days of working capital on every job.
• Large inner-city project deposits missing: Melbourne's commercial construction and fit-out market involves significant project values. No deposit on a $100,000 job is a large exposure.
• GST collected and spent: 10% of every invoice isn't your money. In Melbourne's higher-revenue businesses, this can represent $30,000–$70,000 per quarter that should be held for BAS.

Deposits and Progress Claims in Melbourne's Market

For any project over $1,000–$2,000, deposits are expected in Melbourne's market. Structure:

• 20–30% upfront deposit — standard across Melbourne trades, fit-out, and professional services
• Progress claims at milestones — for larger Melbourne commercial projects, milestone billing every 2–4 weeks is better than a single end-of-project invoice
• Final invoice at completion — the remaining balance

Invoice Terms for Melbourne Clients

7 days is the standard for residential and small business Melbourne clients. For corporate clients:

• Start negotiations at 14 days — don't offer 30-day as a starting point
• If they insist on 30 days, consider whether the job value justifies the working capital exposure
• Include a prompt-payment incentive for early settlement (1–2% discount for payment within 7 days)
• Always include the specific due date on the invoice — not just "Net 30"

The 13-Week Cash Flow Forecast

A 13-week rolling cash flow forecast shows week-by-week projections of money coming in and going out. For Melbourne businesses, the key inputs are:

• Opening cash balance
• Expected invoice receipts by week (based on invoices issued and payment terms)
• Known outflows: Melbourne wages (often weekly or fortnightly), rent, supplier payments
• Quarterly tax obligations: BAS, PAYG, super
• WorkSafe Victoria premium renewal (annual, but budget the cash reserve monthly)
• Victorian payroll tax if applicable

A negative projected cash balance at any point in the 13 weeks gives you the lead time to arrange a facility, accelerate invoicing, or defer a discretionary outflow — rather than discovering the problem the week it happens.

The GST Separate Account Strategy for Melbourne

Move 10% of every GST-inclusive payment received into a dedicated "GST Reserve" account immediately. In Melbourne, where businesses often operate at higher revenue levels, this discipline can mean the difference between a $50,000 BAS bill being manageable or being a crisis.

Open a separate savings account labelled "GST Reserve." Set up an automatic transfer rule: when revenue arrives in your operating account, transfer 10% immediately. Don't touch it except to pay the BAS.
