What “lumpy” really means
Revenue is lumpy when a few large receipts make up most of your income and they arrive at irregular times. An architect might receive three big payments in a quarter and nothing for six weeks. An events company might earn half its year in November and December. A kitchen manufacturer might be paid on installation, weeks after most of the cost has been spent.
Lumpy revenue isn’t the same as low revenue. The problem is timing: costs are smooth, income isn’t.
Why it matters more than people think
When revenue is lumpy, three things happen:
- Payroll stress. Wages are due every week or fortnight regardless.
- Decision distortion. Owners feel rich after a big payment and cut back sharply before the next, leading to stop-start investment.
- Tax surprises. A big receipt near balance date can push up both terminal and next year’s provisional tax.
The goal isn’t to make revenue perfectly even. It’s to make sure the dips are predictable and survivable.
Tactic 1: Change when customers pay
The most powerful lever is the payment schedule on new work.
- Deposits. Ask for a deposit when work is confirmed. Many trades and custom manufacturers take 20–50% upfront to cover materials.
- Milestone billing. Break projects into stages — design, build, install — and invoice as each is completed.
- Progress claims. In construction, serve regular payment claims rather than waiting for completion. Our guide to payment claims and debtor days explains how.
- Retainers. Professional firms can move clients from project fees to monthly retainers for ongoing work.
- Pay-in-advance packages. Tourism businesses can sell pre-season passes or multi-visit packs.
Tactic 2: Add steadier income streams
Look for services that generate regular, smaller amounts:
- A landscaper adding monthly garden-maintenance contracts alongside big design-and-build jobs.
- An IT consultancy adding managed-service support at a fixed monthly fee.
- A winery adding a wine club with quarterly shipments.
- An activity tourism business adding corporate team-building in the shoulder season.
These streams rarely replace the big jobs, but they fund the fixed costs between them.
Tactic 3: Shift costs to match income
Some costs can move to where the cash is:
- Schedule maintenance and capital purchases just after peaks, not before.
- Negotiate seasonal rent with your landlord (lower in the off-season, higher in the peak).
- Use casual or contract staff for peaks and keep a smaller permanent core.
- Ask suppliers for terms that line up with your receipts. See negotiating supplier terms.
Tactic 4: Pay yourself a steady salary
Owners who take drawings whenever cash is available make lumpy revenue worse. Set a fixed monthly amount you pay yourself, and leave the rest in the business until the year’s shape is clear. It’s a simple discipline that makes the business’s cash flow easier to read — for you and for any lender.
Tactic 5: Ring-fence tax
Every time a big receipt lands, move a set share into a separate tax account straight away. That money is not yours to spend; it belongs to GST, PAYE and income tax. Businesses that do this rarely face a tax crunch.
Tactic 6: Build a buffer and a backstop
Even with all of the above, some gaps will remain. Cover them with two layers:
- A cash reserve, built from strong months, for small and medium surprises. See building a cash buffer.
- A standby facility, such as a business line of credit, for gaps bigger or longer than the reserve can handle.
Arrange the facility after a strong period, when your bank statements show the business at its best.
Measuring whether it’s working
Track two numbers each month:
- Lowest closing bank balance in the month. Is it rising over time?
- Share of revenue from the top three receipts. Is it falling as steadier streams grow?
If both trend in the right direction, your revenue is getting smoother, even if it never becomes perfectly flat.
A quick self-check
| Question | If “no”… |
|---|---|
| Do new jobs include a deposit or milestone schedule? | Start with your next quote |
| Do you have at least one regular monthly income stream? | Identify one service you could offer monthly |
| Is tax money moved aside when received? | Open a separate tax account this week |
| Do you know your lowest expected balance this year? | Build a seasonal cash flow plan |
| Is funding arranged before you need it? | Look at standby working capital |
When you need funding to bridge the gaps
If your plan shows a gap that tactics alone won’t close, Capital On Call can help you put capital on call. Lines of credit suit businesses usually trading six months or more, and property-secured loans of $20,000 to $1m suit larger needs. The 60-second enquiry is free and doesn’t affect your credit score.
