Tariffs and Small Business: What They Could Mean for Your Bottom Line

If you own a small or midsize business, you probably have enough to think about without trying to keep up with every change in trade policy.

You are already watching sales, payroll, vendors, customers, employees, expenses, and cash flow. Then you hear that tariffs have changed, another round of tariffs may be coming, or a supplier has increased its prices.

The natural question is: What does this actually mean for my business? That is the question I think is most important.

Tariffs do not affect every business in the same way. The impact can depend on what you buy, where products or materials come from, how your suppliers source their products, how much inventory you carry, and how you price what you sell.

And you may not see the word “tariff” anywhere in your bookkeeping records.

Instead, you may simply notice that a supplier invoice is higher than it used to be. Your cost of materials has increased. The inventory you need to maintain is costing more. A project you quoted several months ago is not as profitable as you expected. Or your sales look good, but there seems to be less money left over.

That is why I believe the most useful approach is not to panic over the latest headline. It is to understand what is actually happening in your business.

Here are some areas I would recommend looking at.

Start With Your Actual Costs

The first place I would look is your vendor and supplier costs.

If you purchase products, materials, equipment, components, packaging, or other items from suppliers, compare what you are paying today with what you were paying six or twelve months ago.

You don't have to start by analyzing every purchase your business makes. Start with the expenses that matter most.

Look at your largest vendors and your biggest categories of direct costs. Ask yourself:

• Has the price of anything increased significantly?

• When did the increase begin?

• Is the increase affecting a product or material you purchase regularly?

• Has the supplier explained why the price changed?

• Are there alternative products or suppliers available?

• Has the cost changed enough to affect your profit margin?

This is where having current, accurate bookkeeping becomes especially valuable.

Your books shouldn't simply tell you how much you spent last year. They should help you see what is changing in your business now.

Current U.S. trade policy continues to change by country, product, and specific trade action. For example, the U.S. Trade Representative announced additional actions involving certain Canadian products in September 2026. That is one reason I would be careful about making broad assumptions about how a tariff applies to every business or every imported product.

If you are directly importing goods, your situation may also require guidance from a customs broker or qualified tax professional regarding the specific products and classifications involved.

But even if you are not importing anything yourself, there is still a business question worth asking:

Have my costs changed? That is the part you can see in your own numbers.

You May Not Import Anything—and Still Feel the Impact

This is one of the areas I think can be easy to overlook.

You might say, “We don't import anything, so tariffs don't affect us.”

Maybe. But I wouldn't assume that without looking at your costs.

Your supplier may purchase imported materials or products. Your distributor may be dealing with increased costs. A manufacturer somewhere earlier in the supply chain may be paying more for components.

Eventually, some of those increased costs can work their way through the supply chain.

That does not mean every price increase is caused by tariffs. There can be many reasons a vendor changes pricing, including labor, transportation, materials, demand, exchange rates, or other operating costs.

That is exactly why I prefer looking at the numbers rather than assuming.

If an item that cost your business $60 six months ago now costs $66, that six-dollar difference matters whether the invoice says “tariff” or not.

Watch Your Gross Margin, Not Just Your Sales

This is one of the biggest things I would want a business owner to pay attention to.

It is easy to look at revenue and feel good because sales are up.

But what if the cost of producing those sales has increased even faster?

For example, let's say you sell a product for $100 and your cost is $60.

Your gross profit is $40, and your gross margin is 40%.

Now imagine your cost increases to $66 while your selling price remains $100.

Your gross profit has dropped to $34, and your gross margin has fallen to 34%.

You are still selling the product for $100.

You may even be selling the same number of products.

But you are making less money on every sale.

If you sell 200 of those products in a month, that difference represents $1,200 less in gross profit for that month.

That is why revenue alone doesn't tell the whole story.

When costs change, I want to know what is happening to gross profit and gross margin.

If your bookkeeping doesn't make those numbers easy to understand, that may be a sign that your financial information needs a closer look.

Pricing Is a Business Decision, Not Just a Reaction

Once you know your costs have changed, the next question is naturally:

Should I raise my prices?

There isn't one answer that is right for every business.

I wouldn't recommend simply taking a 10% increase in one of your costs and automatically adding 10% to your customer's price.

Before changing prices, I would want to understand the bigger picture.

Look at:

• Your current cost

• Your previous cost

• Your current selling price

• Your gross profit

• Your gross margin

• How important the product or service is to your customers

• What your competitors are charging

• Whether customers have alternatives

• Whether there are alternative suppliers or materials available

• How much the change affects your overall profitability

The U.S. Small Business Administration emphasizes the importance of understanding costs, margins, pricing, and break-even points when making pricing decisions.

I think that is especially important when costs are moving.

You don't want to make pricing decisions based entirely on fear.

At the same time, you don't want to keep your prices unchanged for months while your costs quietly eat away at your profit.

The goal is to understand what is happening and make a decision that makes sense for your business.

Don't Forget About Cash Flow

There is another side to rising costs that doesn't always get enough attention: cash flow.

Profit and cash flow are not the same thing.

Suppose you need to spend more money to purchase the same amount of inventory.

You may eventually make a profit when you sell that inventory, but your cash has to leave the business first.

That can create pressure, particularly for a business that already operates with a tight cash cushion.

You may notice:

• Your inventory purchases are increasing.

• Your accounts payable balance is growing.

• More cash is tied up in inventory.

• You are using a line of credit more often.

• Your bank balance is lower even though sales are steady.

• You are waiting longer to collect customer payments.

• You are having to purchase larger quantities to manage vendor pricing or availability.

  
  

None of these automatically means your business is in trouble.

But they are signals worth understanding.

If your business is carrying inventory, remember that inventory and cost of goods sold are connected to how your financial results are reported. The IRS provides specific rules around inventory accounting and cost of goods sold, and the appropriate treatment can depend on your accounting method and circumstances.

That is an area where your bookkeeper and tax professional should be working from the same information.

Take a Closer Look at Your Inventory

If you are an inventory-based business, I would also recommend looking beyond the total dollar amount sitting on your balance sheet.

Ask what that inventory is actually doing for you.

Are your fastest-selling products still the most profitable?

Are some products becoming more expensive while your selling prices have stayed the same?

Are you carrying more inventory because you are concerned about future price increases?

Are there items sitting on your shelves that are tying up cash but not producing enough profit?

Sometimes the issue isn't simply that inventory costs more.

The bigger issue may be that too much of your cash is tied up in inventory that isn't moving quickly enough.

That is a business decision worth looking at with your numbers in front of you.

Service Businesses Aren't Automatically Exempt

When people hear “tariffs,” they often think about retailers, manufacturers, wholesalers, or companies importing physical products.

But service businesses can feel the effects too.

Maybe you are a contractor buying equipment or materials.

Maybe you provide a service that requires specialized supplies.

Maybe you purchase technology, components, tools, or equipment from vendors whose costs have increased.

Or maybe you quoted a project six months ago based on the costs you had at the time.

That last situation deserves special attention.

Imagine you quoted a project for $25,000 and expected your direct costs to be $10,000.

If those costs later increase to $11,500 before the project is completed, you have lost $1,500 of expected gross profit if your customer price remains unchanged.

The project didn't get smaller.

The customer didn't necessarily pay you less.

Your underlying economics changed.

For businesses that provide estimates or fixed-price projects, it can be especially important to know how quickly your direct costs are changing.

Talk to Your Vendors

Your vendors can sometimes provide information that your financial statements cannot.

If you are seeing significant price increases, I think it is reasonable to have a conversation with your supplier.

You might ask:

• What is driving the price increase?

• Is this increase temporary or expected to continue?

• Are there alternative products available?

• Are there domestic sourcing options?

• Are there volume discounts?

• Are there changes coming that I should plan for?

• Can you provide advance notice of future price changes?

  
  

You don't necessarily need to change vendors.

Sometimes simply understanding what is coming can help you make better purchasing and pricing decisions.

And if a major vendor is increasing prices, knowing about it before the next several invoices arrive gives you more time to respond.

Know Your Break-Even Point

Another number worth understanding is your break-even point.

Your break-even point is essentially where your revenue covers your costs, leaving you with neither a profit nor a loss.

The SBA provides a basic break-even formula:

Fixed Costs ÷ (Selling Price – Variable Cost) = Break-Even Point in Units

Why does that matter when costs are increasing?

Because when variable costs rise, your contribution from each sale can fall.

That means you may need to sell more products or services simply to reach the same break-even point.

You don't necessarily need to become an expert in financial modeling to benefit from this information.

You just need to know enough about your numbers to answer a few basic questions:

How much does it cost me to deliver what I sell?

How much do I make on each sale?

How much do I need to sell to cover my overhead?

Is that changing?

Those answers can make pricing and planning decisions much easier.

A Simple Tariff Impact Checkup

If you're wondering where to start, I would keep it simple.

Set aside some time to review the areas most likely to be affected.

1. Review your largest vendors

Pull your largest supplier expenses and compare current costs with costs from six to twelve months ago.

2. Identify meaningful cost increases

Don't worry about every small fluctuation. Look for the increases that could materially affect your business.

3. Check your gross margin

Look at whether you are making the same percentage of profit on your products or services as you were previously.

4. Review your pricing

For products or services with significantly higher costs, determine whether your current pricing still supports the margin you need.

5. Look at inventory

If you carry inventory, determine whether rising costs or slower-moving products are tying up more cash.

6. Look at cash flow

Ask whether increased purchasing costs are putting additional pressure on your available cash.

7. Talk to your vendors

Find out what they know about future pricing and whether alternatives exist.

8. Decide what actually needs to change

Not every cost increase requires a price increase. Not every price increase requires a supplier change.

The point is to understand your options before making the decision.

What I Wouldn't Recommend

There are a few reactions I would be cautious about.

Don't raise every price immediately.

Some costs may have changed very little, while others may have changed substantially. A blanket increase may not make sense.

Don't buy huge amounts of inventory simply because you are afraid prices will increase.

There may be situations where purchasing ahead makes sense, but tying up too much cash in inventory can create its own problems.

Don't assume every vendor price increase is caused by tariffs.

Ask questions and look at the actual numbers.

Don't make decisions based only on revenue.

If sales are growing while margins are shrinking, that growth may not be helping your bottom line as much as it appears.

And don't wait until tax time to discover that your margins have changed.

By then, you are looking backward.

Your bookkeeping should give you information you can use while you are running the business—not just information you hand to your tax professional once a year.

The Most Important Question Is: What Is Happening in Your Business?

There is a lot of noise surrounding tariffs and trade policy, and that noise can make it difficult to know what deserves your attention.

I don't think you need to understand every tariff announcement to make good business decisions.

What you do need is a clear picture of your own numbers.

If your costs are rising, know by how much.

If your margins are changing, know which products or services are affected.

If inventory is consuming more cash, understand why.

If pricing no longer gives you the margin you need, know before the problem becomes significant.

And if nothing has materially changed for your business, that's useful information too.

Not every headline requires action.

That is one of the reasons I believe good bookkeeping is so important. Your books should do more than record what already happened. They should help you understand what is happening in your business so you can make decisions with greater confidence.

A Final Thought

Tariffs may be part of the reason your business costs are changing, or they may not be.

Either way, the place I would start is the same: look at your numbers.

Look at what you are paying your vendors.

Look at your gross margins.

Look at your pricing.

Look at your inventory.

Look at your cash flow.

Then ask what those numbers are telling you.

You don't have to make every decision today. But having accurate, timely financial information gives you something extremely valuable as a business owner: the ability to make decisions based on what is actually happening in your business rather than what you think might be happening.

And if you are not sure what your numbers are telling you, that's important information too.

If your books aren't current enough to give you a clear picture of your costs, margins, and cash flow, we'd be happy to help you get a better understanding of what is happening in your business. My goal isn't simply to keep your books organized. I want you to have financial information you can actually use to run your business, make informed decisions, and move forward with confidence.
