Plugging the Profit Leaks: How Small Costs Eat Away at Your Business

/

In our last post, we broke down the basics of gross profit and why it’s such a vital number for solopreneurs and small teams. But even when you have a solid handle on your main costs and pricing, it’s surprisingly easy for small expenses to quietly eat away at your gross profit. Stop the leaks.

These hidden “leaks” can happen in any business—whether you sell products, services, or both. The good news? Once you learn where to look, you can start patching these profit drains and protect your margins.

Where Does Gross Profit Leak Away?

1. Unnoticed Supplier Price Increases
If you haven’t checked your supplier invoices lately, now's the time. Vendors may raise prices a little at a time, and those increases slowly eat into your margin unless you adjust your prices or negotiate better deals.

2. Increased Waste or Shrinkage
This could mean more ingredients tossed at the bakery, unused materials in your project business, or wasted billable hours in a service setting. Even “a little here and there” adds up fast.

3. Unbilled Extras in Services
Did you spend extra hours on a client project but forget to charge for them? Or include small add-ons “just to be nice”? When you consistently underbill, you’re cutting directly into your gross profit.

4. Shipping and Fulfillment Surprises
In product businesses, rising shipping costs or packaging changes can sneak in and quietly reduce what you keep from every sale.

Patch the Leaks & Protect Your Profit

Regularly reviewing your true costs—even the small stuff—can make a huge difference. Consider a quick “gross profit checkup” each month:

  • Compare supplier prices to previous months.

  • Audit invoices or timesheets for uncharged extras.

  • Track waste or overages.

  • Adjust your pricing and processes as needed.

Remember: Knowing your gross profit means more than having the right numbers. It’s about keeping what you earn and building a healthy, resilient business—one where small leaks don’t drain big dreams.

Gross Profit Made Simple: What It Is, Why It Matters, and How to Improve It

/

Gross profit is a critical metric on your business’s income statement, representing the amount of money your business retains after deducting the cost of goods sold (COGS) from total revenue.

For service-based businesses, you may be more familiar with the term “cost of sales”—in either case, it’s about the direct costs tied to delivering your product or service.

Understanding gross profit isn’t just about knowing your numbers—it’s about unlocking the story behind your operational efficiency, pricing strategy, and long-term success.

1. What Is Gross Profit?

Gross profit is the money left over after subtracting your COGS or cost of sales—which includes materials, direct labor, and any costs directly connected to your product or service—from your total sales revenue.

It shows how much profit your business is generating from its core operations before factoring in overhead, marketing, rent, or administrative costs.

Example:
Imagine you own a bakery.

  • You bake a chocolate cake and sell it for $50.

  • The cost to make that cake (ingredients, part of your baker’s time, the cake box) is $20.

Gross profit = $50 (earned) – $20 (cost) = $30.

That $30 is what’s left to cover your other expenses and create actual profit.

2. Why Gross Profit Matters

You might ask—why does this number matter so much? Let’s go back to the bakery example:

  • Checks your pricing: If your cake costs $20 to make but you charge $22, you only have $2 left—likely not enough to run your business sustainably.

  • Reveals business health: If your gross profit is shrinking, it could mean ingredient costs increased or you’ve been offering too many discounts.

  • Guides what you sell: If brownies have a higher gross profit than cakes, it might make sense to focus on promoting brownies more.

3. How to Increase Your Gross Profit

Here are a few practical ways to improve it:

  • Increase prices where the market will bear it.

  • Reduce direct costs by buying in bulk or sourcing quality materials at better prices.

  • Prioritize high-margin products or services so you’re focusing on what’s most profitable.

Bringing It All Together

Gross profit is more than just a line on your financial statement—it’s a clear snapshot of how your business is performing at its core. Whether you’re a solopreneur or leading a small team, regularly tracking and understanding it can help you spot trends, adjust pricing, refine your offers, and make smarter business decisions.

Know your number, protect your margins, and let gross profit be your guide to building a business that’s not just busy—but truly profitable.
