Startup cash and spending operations
Connect a dated cash forecast, existing payment commitments and a cash check for proposed startup spending.
A startup must know what cash it can use, which payments are coming due and what new spending would do to that position. Keep a dated cash forecast, a record of existing commitments and a cash check for proposed spending. The decision is whether the business can meet payments when they fall due under assumptions the team can explain.
Keep the spending plan separate from the forecast
A budget describes what the business wants to happen; a forecast estimates what is likely based on past and current finances. Budgets are generally set for the year and tend to stay stable, while forecasts should move as actual sales, costs and current trends change.
Use the budget to frame planned activity, then use actual financial information to keep the cash forecast grounded in expected events. A profit and loss budget can include non-cash items such as depreciation and invoices raised but not yet paid, and excludes loan payments. It therefore does not, by itself, show whether cash will be available for payments when due.
Budget vs Forecast: Key Differences for Australian SMEs
- Purpose
- Budget: planned activity; Forecast: expected financial outcome based on current reality
- Timeframe
- Budget: typically annual; Forecast: updated regularly (monthly or weekly)
- Non-Cash Items
- Budget includes depreciation, unpaid invoices; Forecast focuses only on actual cash movements
- Flexibility
- Budget: stable; Forecast: dynamic, adjusts to real-world changes
Build a view of cash by payment date
Start with the cash available at the beginning of the forecast. Add expected receipts and subtract expected payments for each period, then carry the closing balance forward. An issued invoice is not cash received. Mark receipts as received, due under agreed terms or less certain, and use a realistic expected arrival date.
Choose periods that reveal the decisions ahead. A monthly forecast may show the broad direction while concealing a difficult payment week. Add dates or shorter periods where a large receipt or payment makes timing important. Identify cash that is restricted or otherwise unavailable for general payments.
Include the payments that apply to the business, such as wages, suppliers, loan repayments and relevant tax and superannuation amounts. Check amounts and due dates against current records. State how GST is handled, and account for applicable GST cash payments without omitting or counting them twice.
Customer and supplier payment terms affect when cash is available, even when sales and expenses are recorded. Compare expected customer receipts with supplier payment dates. Consider timing invoices and payments so customer cash arrives before supplier payments fall due where possible.
Key Cash Flow Management Steps for Australian Startups
- Start of Forecast Period
- Initial cash balance as at beginning of period
- Expected Receipts
- Cash inflows from sales, invoices received (GST-inclusive), and other sources
- Payment Due Dates
- Wages, supplier payments, loan repayments, GST, PAYG, superannuation
- Cash Balance Adjustment
- Closing balance carried forward to next period
- Review & Update
- Refresh forecast with actuals; update assumptions based on new data
Distinguish commitments from choices
Show payments the business already owes separately from spending it can still decline, delay or change. An approved purchase may already be a commitment; a budget allocation alone may not be. Check the agreement and the point at which the business became bound.
Some costs can change only after a notice date or another party's agreement. Keep the current payment in the forecast until a different amount or date is confirmed. Record the earliest point at which each proposed change could affect cash. This lets the team compare actions that would help in time with actions that would take effect too late.
Check cash before adding a commitment
When a proposed purchase reaches the business's existing approval route, show its full payment schedule, term and effect on the forecast. A small first payment can lead to a larger later obligation. If the proposal creates a tight period, the authorised decision-maker can change its timing or scope, defer it, or consider a confirmed source of cash. Record the decision and the assumption it relies on.
Supplier selection and contract administration belong in the vendor process; this check supplies the cash information for that decision.
Pre-Commitment Cash Check for Australian Startups
- Confirm full payment scheduleInclude all instalments, terms, and renewal dates
- Assess impact on forecastEvaluate whether the commitment creates a cash shortfall
- Identify alternative fundingCheck if a confirmed source of cash exists (e.g. retained earnings, line of credit)
- Document decision and assumptionRecord who approved, what was assumed, and under what conditions it can be revised
Connect finance inputs to the cash view
Map how money moves from a sale to the bank account and from a purchase request through approval to payment. This makes it easier to see where timing or information gaps could leave the forecast out of step with the business.
Give each recurring input an owner and a consistent place to record it, rather than relying on separate spreadsheets or someone's memory. The finance system should provide one reliable source of financial data, supported by clear workflows. Not every step needs automation, but each step needs an owner.
Australian Startup Cash Management Essentials
- GST HandlingMust be accounted for in cash flow; paid quarterly to ATO via BAS
- PAYG WithholdingWithheld from wages and remitted to ATO monthly or quarterly
Refresh the view when facts change
Name the person maintaining the forecast and the owners of receipt, payroll and payment inputs. Replace elapsed estimates with actual movements, investigate material differences and update future dates. Keep a dated prior view so readers can see what changed.
Where a material receipt or cost is uncertain, compare the working forecast with a more cautious case. If either shows that a payment may not be met, raise the issue before it falls due. A possible funding round, unagreed extension or hoped-for sale is not available cash.
