Sydney service businesses should typically allocate 5-12 percent of target revenue to lead generation, with the exact figure depending on trade type, geographic competition, and growth stage. New businesses need more (10-15%) to build a customer base quickly. Established businesses with strong referral networks can maintain 4-7%. The biggest mistake is treating marketing as an afterthought and spending irregularly.
- 5-12 percent of target revenue is the standard lead gen budget range for Sydney operators
- New businesses typically need 10-15 percent to build momentum
- Emergency trades (plumbing, electrical) can justify higher spend due to higher job values
- Spreading budget across 3 channels is more resilient than concentrating on one
- Track cost per acquired customer, not cost per lead
- Review and adjust budget quarterly, not annually
Sydney service business owners ask us some version of this question at least once a week: 'How much should I be spending on getting new customers?'
The honest answer is: it depends on your trade, your revenue, your area, and your growth ambitions. But there are benchmarks that help most businesses sense-check whether they are under-investing, over-investing, or roughly in the right range.
This post gives you those benchmarks and the thinking behind them.
The percentage-of-revenue benchmark
The most useful starting point is to think about lead generation spend as a percentage of your target revenue. Not your current revenue. Your target.
A plumber doing $400,000 per year and wanting to grow to $550,000 should plan their lead generation budget around the $550,000 target, not the current number. The spend drives the growth; it does not come after.
| Business stage | Revenue range | Suggested lead gen % of revenue |
|---|---|---|
| Just starting | Under $200K | 12-18% |
| Growing | $200K-$500K | 8-12% |
| Established | $500K-$1M | 5-8% |
| Mature business | Over $1M | 3-6% |
These are for businesses relying on lead generation for growth
If your business is primarily referral-driven and lead generation is a supplement rather than the engine, these percentages can be lower. If you are starting fresh with no referral base, they need to be at the higher end.
What different Sydney trades typically spend
Different trades have very different job values, competition levels, and margin profiles. The right lead generation spend for a plumber is very different from the right spend for a carpet cleaner.
| Trade or service | Average Sydney job value | Suggested monthly lead gen spend |
|---|---|---|
| Emergency plumbing | $350-$800 | $1,500-$3,500 |
| General electrical | $300-$600 | $1,200-$2,800 |
| Carpet cleaning | $150-$350 | $600-$1,500 |
| End of lease cleaning | $250-$500 | $800-$2,000 |
| Pest control | $200-$450 | $700-$1,800 |
| Landscaping / lawn care | $200-$600 | $800-$2,500 |
| Painting | $1,500-$8,000 | $1,500-$4,000 |
High-value trades can spend more per lead
A painter whose average job is $4,000 can afford to spend significantly more to acquire each customer than a carpet cleaner averaging $200. The cost per acquired customer is the metric that matters, not cost per lead.
Spreading budget across channels
Concentrating all your lead generation budget into one channel is risky. If that channel changes its pricing or algorithm, or if a competitor outbids you, your lead flow stops.
A resilient lead generation setup spreads budget across three to four channels with different risk profiles. Some channels produce leads immediately (Google Ads, exclusive lead programs). Others compound over time (local SEO, Google reviews). A good mix has both.
Immediate channel (40-50% of budget)
Google Ads or an exclusive lead program. Produces enquiries from month one. Higher cost per lead but immediate return.
Compounding channel (30-40% of budget)
Local SEO, website development, content. Lower short-term return but produces owned traffic that reduces your cost per lead over time.
Reputation channel (10-20% of budget)
Google reviews system, missed call recovery, referral program. Amplifies the value of every other channel. Cheap to maintain, high long-term value.
How Sydney service businesses should think about lead generation ROI
Return on investment for lead generation is straightforward to calculate, but most businesses do not do it. Without this number, you are guessing whether your spend is working.
| Input | Example values | Your business |
|---|---|---|
| Monthly lead gen spend | $1,200/month | |
| Average jobs per month from leads | 14 jobs | |
| Average job value | $420 | |
| Revenue from lead gen jobs | $5,880 | |
| Gross margin (after labour, materials) | 45% | |
| Gross profit from lead gen jobs | $2,646 | |
| ROI (gross profit vs spend) | 2.2x |
If your ROI from lead generation is below 2x gross profit, there is a problem in the chain. Either the cost is too high, the job value is too low, the volume is too thin, or a conversion problem is losing jobs that should be closing.
Track gross profit, not revenue
A job worth $400 might only leave $150 in gross profit after materials and subcontractor costs. Your lead generation spend needs to be measured against that $150, not the $400 invoice. This is why trades with higher margins can justify higher lead costs than those with thinner margins.
Common budget mistakes Sydney service businesses make
- Spending only when quiet, then cutting when busy. This creates boom/bust enquiry cycles.
- Measuring cost per lead instead of cost per acquired customer
- Investing in one channel only (usually Google Ads) and stopping when it gets expensive
- Not tracking where enquiries come from, so cannot optimise the spend
- Treating the website as a one-time cost rather than an ongoing investment
- Underspending in growth phase then wondering why revenue flatlines
Stop-start marketing is the most expensive approach
Pausing lead generation when you are busy creates gaps in the pipeline that are expensive to refill. A steady, consistent spend maintains a flow of new customers that can be managed. On/off spending produces on/off income.
What this article is not claiming
There are no made-up retention percentages or enquiry counts in this piece. The framework above is what we have seen play out for service businesses on our own program and what other operators in the space report, but the numbers that matter for your business are the ones for your suburb and your service category, which we can only work out together.
If you want a sample of what an actual enquiry looks like when it lands, ring us and we will send you a sanitised SMS example from a similar trade. That is more useful than any blog statistic.
