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.
