Why Some Clients Drain Your Profit

I have been an entrepreneur since I was a freshman in college back in 2009, and one of the hardest lessons I have learned is that the wrong clients can hurt your business just as much as having no clients at all. That might sound counterintuitive, especially when you are building a business and someone wants to pay you for your products or services. When a new client comes along, the natural reaction is usually gratitude, excitement, and a desire to say yes. I completely understand that reaction because I have been there myself. But over nearly two decades of entrepreneurship, I have learned that revenue alone does not tell you whether a client is good for your business. Some clients can generate revenue while quietly draining your profit, your time, and your energy. 

That is why I want to explore why some clients drain your profit and what you can do about it. In this post (and the YouTube video linked here and the podcast episode linked here), I’ll walk you through the framework I use to evaluate client relationships and protect the profitability of my business. The answer is more complicated than simply saying that certain clients cost too much money. A client can drain your profitability because they require excessive time, consume disproportionate amounts of energy, or create expenses that are greater than the revenue they generate. I have also learned that not every client needs to be evaluated in exactly the same way. Some clients may be worth keeping even when they are not immediately profitable because of the energy, relationships, or long term opportunities they create. The key is to become intentional about who you serve, how you serve them, and what those relationships are actually costing your business.

Why taking on the wrong clients can hurt your business

When you are starting out, I actually recommend being less selective about your clients than you might be later in your entrepreneurial journey. The reason is simple: you need experience. You need to work with different types of people and organizations to discover who you genuinely enjoy serving and who you do not want to work with long term. You cannot always figure that out from a sales call or a proposal. Sometimes you have to experience the relationship firsthand.

However, I do not believe you need to commit to every potential client for six months or a year just to figure out whether the relationship works. One strategy I use today is to compartmentalize the work and test the relationship first. In certain situations, I offer potential clients the opportunity to work with me one on one for a week. During that period, we are both evaluating the relationship and asking whether we can see ourselves working together over the longer term. I believe entrepreneurs should test their clients just as much as clients test them. A short engagement can reveal things that a contract never will.

The first way clients drain your profit: money

The most obvious answer to the question of why some clients drain your profit is money. Sometimes the revenue you receive from a client is simply lower than the expenses required to serve that client. You might sell a project for a certain amount, but the cost of delivering the project can exceed what you actually collected. When that happens, the more you work with that client, the more money your business can lose.

I experienced this myself during the first several years of entrepreneurship. I wanted to serve people, build relationships, establish credibility, and create long term opportunities. Those are all valuable goals, but they can become dangerous when you stop paying attention to the economics of the relationship. There is nothing inherently wrong with giving away free training, free resources, free trials, or other low cost ways for people to experience your business. In fact, those can be excellent ways to build trust. The problem begins when serving people for free or at a very low price causes your expenses to grow significantly.

The fundamental equation is simple: profit equals revenue minus expenses. If you want to increase profit, you ultimately need to increase revenue, reduce unnecessary expenses, or improve both. That means you should regularly ask yourself whether the cost of serving a particular client makes sense relative to the revenue and long term value that client creates.

The second way clients drain your profit: time

The second way clients drain your profit is through time. This one took me much longer to recognize in my own business. Two clients can pay you exactly the same amount of money while requiring dramatically different amounts of your time. On paper, they look equally profitable. In reality, one may be consuming a significant portion of your capacity.

Imagine that you have ten clients paying you the same amount. Nine of them require a reasonable amount of support, communication, and attention. One client constantly needs additional meetings, revisions, explanations, calls, and follow up. That client may not appear unprofitable when you look only at the invoice. But when you calculate the amount of time you are investing, the economics can look completely different.

Time is a limited resource. There are only 24 hours in a day, and none of us knows exactly how many days we have available to build our businesses and live our lives. Money can potentially be earned again, but time that has already been spent cannot be recovered. That is why I believe entrepreneurs should evaluate clients based on the amount of time they require, not simply the amount of money they pay.

If a client consistently requires significantly more time than your other clients, you have several choices. You can decide not to renew the relationship. You can change the scope of the engagement. Or you can increase the price so that the financial return better reflects the time required. If a client takes twice as much time as another client, it is worth asking whether they should be paying substantially more.

The third way clients drain your profit: energy

The third and, in my opinion, most important way clients can drain your profit is through energy. I did not fully understand this until the later part of my entrepreneurial journey. We talk constantly about money and time because they are relatively easy to measure. Energy is harder to put into a spreadsheet, but that does not make it less important.

Think about the number of hours in your day when you actually have the energy to perform at your highest level. It is significantly less than 24. You might technically have eight hours available for work, but that does not mean you have eight hours of high quality creative, strategic, and productive energy. Some clients can leave you energized and excited to do your best work. Other clients can leave you exhausted before the day is over.

For me, this is a critical consideration because I do not want to spend my most valuable asset entirely on work. I want to have energy for my family, my friends, and the things I enjoy outside of business. If a client consistently consumes a disproportionate amount of my energy, that cost is real even if it does not appear on an income statement.

This is one of the biggest reasons why some clients drain your profit without immediately appearing unprofitable. When your energy is consumed by the wrong client, you have less capacity to serve great clients, create new opportunities, make strategic decisions, and build the business. The opportunity cost can be enormous.

Use an energy, time, and money client scorecard

One of the simplest exercises I recommend is creating a client scorecard. Take a sheet of paper or open a spreadsheet. Put your clients across the top and put three categories down the side: energy, time, and money. Then evaluate every client honestly.

Start by identifying your great clients. These are the people you genuinely enjoy serving. You may be passionate about what they are doing, they may give you energy, they may respect your time, and they may pay you well. These are the relationships you want to understand and replicate.

Next, identify your good or average clients. These clients may not excite you, but they treat you well and provide reasonable financial value. There is nothing inherently wrong with maintaining these relationships. However, you should pay attention if they begin consuming significantly more energy, time, or money than they are worth.

Finally, identify your bad clients. If a client is rude, disrespectful, difficult to work with, or fundamentally misaligned with your values, I would not recommend keeping them simply because they pay you. Sometimes the best business decision is to stop working with them altogether.

When should you raise your prices or let a client go?

Once you complete the scorecard, you can start making more intentional decisions. For bad clients, the answer may be relatively simple: find a way to end the relationship. For good or average clients, one major issue in energy, time, or money may be enough to justify either increasing the price or reconsidering the relationship.

If the problem is primarily time, pricing can sometimes solve the problem. A client who requires significantly more of your attention may be perfectly worthwhile if they are paying appropriately for that attention. You do not necessarily need to abandon every client who requires more work. You need to make sure the economics of the relationship make sense.

Great clients require more nuance. I have had great clients who were not immediately profitable, and I was willing to accept that for a period of time because of how much energy and value the relationship created. But even with great clients, I believe you need boundaries. You need to decide how long you are willing to serve them at a loss and what needs to change in the future.

One approach is to communicate that the investment will increase over time. You might be willing to work together for six months at one price, then adjust the price as the relationship evolves. The goal is not to punish great clients. The goal is to create a sustainable relationship that works for both sides.

Focus on the clients creating the most profitability

Ultimately, I want you to build a business around the clients who give you energy, respect your time, and generate strong financial returns. This is where the 80/20 rule becomes incredibly useful. The Pareto principle suggests that a disproportionate amount of your results can come from a relatively small percentage of your inputs.

In business, that means a relatively small percentage of your clients may be responsible for a significant percentage of your profitability. Your job is to identify those clients and understand what makes them different. What do they value? Why do you enjoy working with them? How much time do they require? What makes the relationship financially attractive?

Once you understand those characteristics, you can begin building your business around them. Instead of constantly trying to acquire more and more clients, you can become more intentional about acquiring the right clients. That can improve your profitability while also creating a business that you actually enjoy operating.

Your next step: evaluate your clients

If you want to understand why some clients drain your profit, do not start by looking only at your revenue report. Start by looking at your relationships. Take your current client list and evaluate each one according to energy, time, and money. Be honest about which relationships energize you, which ones consume your capacity, and which ones are financially worthwhile.

You do not have to make every decision overnight. The purpose of this exercise is to create awareness so you can make better decisions. Maybe you need to raise the price for one client. Maybe you need to change the scope of another engagement. Maybe you need to stop renewing a contract. Or maybe you discover that one of your clients is an incredible relationship that you should be doing more to support.

The most important thing I want you to take away is that more clients do not automatically mean a more profitable business. The right clients can help you create more impact, while the wrong clients can consume the very resources you need to grow. If you become intentional about protecting your energy, your time, and your money, you give yourself a much better opportunity to build a profitable and sustainable business.
