You already track one number — how much money came in last month. That's the one everyone tracks. But it's also a lagging indicator, which means by the time you see it drop, it's already too late to fix. The 5 numbers below tell you where your business is heading, not where it's been. We'll go through each one in plain English, with the formula and a real example you can copy tonight.
1Why tracking revenue alone isn't enough
Revenue is the scoreboard at the end of the match. Useful for telling you who won, useless for helping you win.
The problem: if you only look at revenue, you can't tell the difference between a good month that was lucky and a good month that was earned. Same for bad months. A quiet October might mean your marketing is broken — or it might just be a slow month that corrects itself in November.
Five other numbers give you the picture revenue can't. Track these monthly and you'll stop flying blind.
2Customer Acquisition Cost (CAC)
What it is: How much it costs you — in marketing and sales spend — to land one new customer.
Formula: Total marketing + sales spend last month ÷ Number of new customers last month.
Example: You spent $2,000 on ads and $500 on the quoting app you pay for. You got 10 new customers. Your CAC is $250.
Why it matters: If your average job is worth $400 and your CAC is $250, you only keep $150 before delivery costs. If you raise your average job to $800 without raising CAC, you've doubled your profit per customer without doing more work.
Most small businesses don't know this number, and it's the first one that tells you whether your marketing is working.
3Customer Lifetime Value (CLV)
What it is: How much a customer is worth to your business across everything they ever buy from you — not just their first job.
Formula: Average order value × Average number of orders per customer × Average years they stay with you.
Example: A physio clinic charges $120 per session. Their average patient comes 8 times over 2 years. CLV = $120 × 8 × 2 = $1,920.
Why it matters: If your CAC is $150 and your CLV is $1,920, you can afford to spend much more on winning each customer than you thought. Most small businesses under-spend on marketing because they're comparing CAC to the first sale instead of the full relationship.
The average small business misjudges CLV by 60% or more, according to Harvard Business Review data cited across 2024-2025 marketing analytics reports. At Bare Bayside Labs, we see this every week — owners convinced they "can't afford" $100 per lead when their actual lifetime customer value is over $2,000.
4Win rate
What it is: Of every quote or proposal you send, what percentage turns into a paying job.
Formula: Jobs won ÷ Quotes sent × 100.
Example: You sent 20 quotes last month. 6 turned into jobs. Your win rate is 30%.
Why it matters: Win rate tells you whether the problem is your pricing, your pitch, or your positioning. A low win rate with lots of quotes means you're attracting wrong-fit leads. A high win rate with few quotes means your marketing is leaving money on the table.
Watch this number month over month. A win rate that's dropping is usually the first sign a competitor has started eating your lunch.
5Sales cycle length
What it is: The average time between a lead first reaching out and them paying you.
Formula: Date of payment − Date of first contact, averaged across recent customers.
Example: Your last 10 customers first contacted you anywhere from 3 days to 6 weeks before paying. Your average is 18 days.
Why it matters: If your sales cycle is getting longer, something is slowing the decision down. It might be your follow-up (or lack of it). It might be pricing objections you're not addressing. It might be that competitors are making prospects shop around more.
A shrinking cycle means your process is getting sharper. A growing one needs attention before it hurts revenue.
6Pipeline coverage
What it is: The total value of open quotes and prospects you're currently chasing, compared to your monthly revenue target.
Formula: Sum of all open quote values ÷ Monthly revenue target.
Example: Your revenue target is $30,000/month. You have $90,000 of open quotes being considered. Your pipeline coverage is 3x.
Why it matters: Most small businesses need roughly 3x coverage to hit target, because not every quote closes. If your coverage drops below 2x, revenue in the next 60 days is going to suffer — and you still have time to do something about it.
This is the single best "leading indicator" you can watch. Low coverage today = low revenue in a couple of months. Spot it early, fix it early.
7A full example tying them together
Let's say you run a bookkeeping practice.
- CAC: $200 (ads + your quoting time)
- CLV: $3,600 (average client stays 3 years at $100/month)
- Win Rate: 40%
- Sales Cycle: 14 days
- Pipeline Coverage: 2.5x (target $20K, open quotes $50K)
From those five numbers, you know: your marketing is highly profitable (CAC is 5% of CLV), your quoting is solid (40% close rate), decisions happen quickly (2 weeks), but your pipeline is borderline — you need more leads this month or next month's revenue will dip.
One spreadsheet. Five numbers. The whole health of your business at a glance.
Businesses that track at least 3 of these metrics monthly grow revenue 23% faster on average than those tracking revenue alone (synthesised from SaaS Capital benchmark data 2024). At Bare Bayside Labs, we see the biggest change in owners who build a simple monthly dashboard — usually 30 minutes of setup, then 5 minutes a month to update.
Key takeaways
- Revenue is a lagging indicator — by the time it drops, it's too late to fix the cause.
- CAC tells you if marketing is profitable — compare it to CLV, not to the first sale.
- CLV is almost always higher than you think — and it unlocks bigger marketing budgets without risk.
- Win rate and sales cycle length catch problems in your sales process weeks before revenue suffers.
- Pipeline coverage is the best leading indicator — aim for 3x monthly target.
- You don't need software — a five-row spreadsheet, updated monthly, beats 90% of small businesses.
Common questions
How often should I update these numbers?
Monthly is plenty for most small businesses. Calculate them once at the end of each month and write the figure down so you can see month-over-month trends. Weekly tracking is overkill unless you're running a high-volume operation.
Do I need a CRM to track this?
No. A simple spreadsheet with 12 rows (one per month) and 5 columns (one per number) is enough to start. A CRM makes it easier later because the numbers calculate themselves, but don't wait for software to start tracking.
What if my business is too small for some of these?
If you have fewer than 10 customers, focus on CAC and Win Rate first. CLV needs history you might not have yet, and pipeline coverage only matters once you have a steady flow of quotes.
What counts as "marketing spend" in CAC?
Any dollar you spent trying to win customers — ads, directory listings, website costs, subscriptions to tools, even your time at networking events if you want to be strict. Most owners count hard money first (ads, tools) and add time later.
Which number should I look at first?
Win rate. It's the fastest to calculate, the easiest to influence, and the number that tells you the clearest story about whether your sales process is working.
