A profitable business can still run out of cash. Insurance renewals, equipment failure, tax payments and a weak booking week do not always arrive when invoices are being paid. The right buffer is not a fashionable round number. It is enough to carry unavoidable costs through a realistic interruption. ## List the costs that continue when work slows Start with expenses that cannot disappear quickly: - vehicle repayments or essential transport costs - insurance - phone and internet - software - storage - payroll and super where employees exist - loan commitments - registrations - minimum product replacement - accounting or bookkeeping commitments Variable products used only when cleaning may fall during a quiet period. Fixed commitments do not. ## Choose the interruption you are protecting against A buffer may cover: - two weeks unable to work - a major vacuum or machine replacement - a cluster of late invoices - a seasonal slowdown - a vehicle repair - an unexpected insurance excess - an employee payroll cycle before customers pay A solo residential cleaner and a small team with weekly payroll carry different cash risks. The amount should reflect the business that exists, not a generic rule from another industry. ## A simple buffer formula **Cash buffer target = essential monthly costs × chosen months of cover + known near-term risks** Optional additions: - a minimum owner drawing - an equipment replacement allowance - an insurance excess - a payroll timing allowance Do not include GST or tax reserves as if they were available buffer money. ## Worked example A solo cleaner identifies A$2,400 in essential monthly business and personal support costs that the business must carry during a short interruption. They choose two months of cover and add A$1,200 for a likely equipment or vehicle issue. **A$2,400 × 2 + A$1,200 = A$6,000 target buffer** This is an example, not a recommended amount for every cleaner. A small team with payroll may need a larger and more carefully timed reserve even when monthly revenue is higher. ## Where should the buffer sit? The business needs access to the money when something goes wrong. It also needs enough separation that the owner does not casually spend it. A separate savings account or clearly named bank bucket can work. Consider account access, deposit protection, interest, fees and the need for fast availability. This article does not recommend a particular bank or financial product. ## When it is reasonable to use the reserve Use it for the risk it was built to carry: - keeping essential bills paid during an interruption - urgent replacement of equipment needed to earn revenue - short invoice-timing gaps - unavoidable payroll timing It is not a marketing budget, a holiday account or proof that an underpriced service can continue indefinitely. ## Refill it deliberately After using the buffer, add a temporary weekly or monthly refill amount to the business plan. Do not wait for one unusually large job. A steady refill is more reliable and reduces the chance the reserve stays permanently half-empty. ## Frequently Asked Questions ### Is a cash buffer the same as profit? No. Profit is an accounting result for a period. A cash buffer is money actually held and available for a defined purpose. ### Should a sole trader keep a personal emergency fund too? Business and personal risks are different. Many owners choose separate reserves. The right structure depends on personal circumstances. ### Can unpaid invoices count toward the buffer? No. Money owed is not the same as money held. Treat payment timing as a separate cash-flow risk. ## Summary Build the buffer from essential weekly or monthly costs. Keep tax and GST reserves separate. Decide whether the buffer protects only the business or also a minimum owner drawing. Refill the reserve after using it instead of treating it as permanent spare cash. ## Sources - [Choose a pricing strategy](https://business.gov.au/products-and-services/choose-a-pricing-strategy) — Australian Government business.gov.au; checked 2026-08-02. - [Record keeping for business](https://www.ato.gov.au/businesses-and-organisations/preparing-lodging-and-paying/record-keeping-for-business) — Australian Taxation Office; checked 2026-08-02. ## Related Tidyly Resources - [Financing Equipment and Vehicles for a Growing Cleaning Business](https://tidyly.au/resources/cleaning-business-equipment-finance-australia) - [Cleaning Business KPIs: The Numbers Worth Tracking Every Month](https://tidyly.au/resources/cleaning-business-kpis) - [How to Reduce Late Payments in a Cleaning Business](https://tidyly.au/resources/how-to-reduce-late-payments-cleaning-business) - [Cleaning Business Break-Even Calculator: How Many Jobs Do You Need?](https://tidyly.au/resources/cleaning-business-break-even-calculator)
