Most dashboards we see at Quebec SMBs are full of numbers that do not pay an invoice. Likes, impressions, "reach", followers. It makes for a handsome report and it flatters the ego, but it says nothing about the real health of your business.
An owner does not need fifty metrics. They need five. Five numbers that connect what you spend on marketing to what it brings back in paying customers. The rest you can forget without losing anything.
01 Customer acquisition cost (CAC)
This is what a new customer costs you, all in. The formula fits on one line: take everything you spent on marketing and sales in a month, divide by the number of new customers signed that month. If you put in $4,000 of ads and sales time and signed 10 customers, your CAC is $400.
You look at this number monthly. Not daily. If it climbs while your sales do not, something has broken: a channel running out of steam, a saturated audience, a follow-up going off the rails. CAC is your most honest alarm bell.
02 Customer lifetime value (LTV)
CAC means nothing on its own. Paying $400 to acquire a customer is catastrophic if that customer spends $300 once. It is a bargain if they come back for five years and leave $8,000 behind. Lifetime value is exactly that: what a customer brings you over the whole relationship.
Simple calculation: average order value, times the number of purchases per year, times the number of years a customer stays. A restaurant, a garage and a dental clinic have very different LTVs. You do not need a perfect number, just a reliable order of magnitude.
The only rule that counts: your LTV should be worth at least three times your CAC. Below that, you are working hard to enrich your ad platforms, not your business.
03 Cost per lead and lead-to-customer conversion rate
These two go together, and this is where a lot of SMBs get caught out. Cost per lead (CPL) is your ad spend divided by the number of enquiries received. Easy to get, and often the only number agencies show you. The trap: a low CPL is worthless if those leads never sign.
The number that really counts is the conversion rate: out of 100 leads received, how many become customers? An $8 CPL converting at 2% costs you more in the end than a $25 CPL converting at 15%. Always look at the two together, never CPL on its own.
04 Return on ad spend (ROAS)
ROAS answers the most direct question: for every dollar put into advertising, how much comes back in revenue? You spend $1,000, you generate $4,000 in attributable sales, your ROAS is 4. A ROAS of 1 means you are burning money just to make noise.
Beware the "platform ROAS" trap. Meta and Google will show you a flattering figure by claiming credit for sales that would have happened anyway. Trust your actual revenue, not just the ad platform's dashboard. The right ROAS depends on your margin: a low-margin business needs a higher ROAS to come out ahead.
05 Lead response time
The only number on this list that is not financial, and yet the one that sabotages the most budgets. How much time passes between someone filling in your form and you calling them back? If the answer is measured in hours, you are leaving money on the table.
Five numbers, one page, twenty minutes a month. That is all it takes to steer your marketing like an owner rather than a spectator.
