Revenue growth can mask shrinking profit. They're not the same number.
The most common profit leaks are inconsistent discounting, pricing that hasn't kept up with costs, and software bloat.
Each has a fix that takes less time than you think.
This all matters because profit is the metric that pays you
Most business owners watch revenue. When it goes up, they assume the business is doing well. The problem is, the whole time revenue is going up, profit could be going down.
It's death by a thousand papercuts. No single line item kills you. It's the discount you gave because it felt right, the price you haven't updated in 18 months, the two software subscriptions doing the same job. Each one is small. Together, they start to impact your margin, and eventually how much you as a business owner take home.
After reviewing 80+ books last month - here are the biggest profit leaks we found.
Discounts are not a problem. Random discounts are.
When your team (or you) negotiates discounts on the fly, your margin on each sale becomes unpredictable. A 10% discount on a $5,000 project is $500 off your bottom line. If your margin on that project was 30%, you just gave away 17% of your profit.
Multiply that across 20 projects a month. It's not pretty.
The fix: build a discount structure.
Decide in advance what discounts are available, what they're worth, and what you get in return.
For example: 5% off for a client who agrees to a case study, 5% off for quarterly or annual payment upfront.
Your team still has flexibility. Every discount has a reason. And your margin is protected because you decided the terms before the conversation started.
If you set your prices two years ago and haven't touched them, you're almost certainly making less per dollar of revenue than you were.
Inflation doesn't just hit groceries. It hits your suppliers, your software, and your payroll. If your costs went up 8% over the last two years and your prices didn't move, that 8% came directly out of your margin.
This is especially common with service-based businesses in Canada, where wage expectations have risen faster than most owners have adjusted their rates.
The fix: start with new customers.
Update the pricing on your website or adjust what you quote during your next sales conversation. You don't need a formal pricing review to test this. Change it, run it for 30 days, and see if close rates hold.
Software subscriptions are the easiest cost to ignore. They're small individually, they auto-renew, and no one has time to review them.
But software is moving fast. Tools that were niche two years ago now have overlapping features. There's a good chance you're paying for two products that do the same thing, or paying for a plan with features you're not using.
The fix: audit your stack once a year. Pull every subscription. For each one, ask:
Does this do something nothing else does?
Is someone actually using it?
If the answer to either is no, cut it.
Sarah runs a 12-person marketing agency in Ontario. Revenue grew 15% over the last two years. She assumed profit grew with it.
When her accountant ran the numbers, her net margin had dropped from 24% to 17% over the same period.
The culprits: her team had been discounting proposals without a formal policy (averaging about 12% off on competitive bids), her project rates hadn't changed since 2022, and her software stack had grown from eight tools to 14 (three of which had overlapping functions).
None of those decisions felt significant at the time. Together, they cost her roughly $68,000 in margin on $850,000 in revenue.
Run through these. If you're unsure on more than two, your profit is probably leaking.
Do you have a written discount policy your team follows?
Have you updated your prices in the last 12 months?
Do you know your margin on each service or product line?
Have you audited your software subscriptions in the last year?
Do you review your cost structure at least annually?
How do I know if my profit is actually shrinking?
Pull your P&L report for this year versus two years ago. If revenue grew but margin percentage dropped, profit is leaking somewhere. If your books are up to date this should take 5 minutes.
When should I raise prices?
Start with new customers. Adjust your pricing for incoming work before touching existing clients. If you've had the same rates for more than 12 months and your costs have gone up, you're overdue.
How much is software bloat actually costing me?
More than it looks. A $50/month subscription sounds small. Ten of them is $6,000 a year, before you factor in the ones you're paying for and not using. Audit the stack annually and you'll almost always find $1,000 to $5,000 in redundant spend.
Is this a sign I need a bigger overhaul?
Not necessarily. These fixes are operational, not structural. Most businesses can close a significant margin gap by addressing discounting, pricing, and software without changing their service mix or business model. Start there before assuming the problem is bigger than it is.
