What is customer churn?
Customer churn is the event in which a customer stops doing business with a company or ceases using its products or services. It represents the loss of a customer, whether through cancellation, non-renewal, switching to a competitor, or inactivity.
For example, let's say you run a project management software with 250 active corporate customers on April 1. During the month, 2 enterprise accounts don't renew due to budget cuts, and 3 small-business customers cancel after switching to a cheaper tool. That means 5 companies churned in April.
You can calculate customer churn using this formula:

Different types of churn
You may come across multiple types of churn. Here are some common ones:
User churn: User churn refers to the number or percentage of individual users who stop using your product or service during a specific period. It's focused on how many people walked away regardless of how much revenue they generated.
Revenue churn: It is the percentage of recurring revenue lost due to downgrades, cancellations, or non-renewals. It focuses on monetary impact rather than user count.
Voluntary churn: Voluntary churn occurs when a customer intentionally chooses to stop using a product or service. This often results from dissatisfaction, a better alternative, unmet expectations, or a change in needs.
Involuntary churn: Involuntary churn happens when customers are lost due to unintentional things like failed payments, expired cards, or technical issues.
Subscription churn: When a user or company formally cancels or chooses not to renew their active product subscription with you.
Negative churn: When the expansion revenue from existing accounts (via upsells or upgrades) exceeds the revenue lost to churned customers.
5 reasons why your customers might be churning
If you want customers to stick around, it's important to understand why they leave in the first place. In B2B SaaS, churn often includes problems with the product, but that's just one piece of the puzzle. Let's look at some of the most common reasons for customer churn:
Product problems
Product-related issues are one of the primary drivers of customer churn, particularly in B2B SaaS. Customers expect software that is reliable, efficient, and easy to use. When their experience falls short of these expectations, they begin to disengage. Several factors within a product can contribute to churn, and understanding them can help you pinpoint where your product might be falling short:
Lack of essential features: When key features are missing, customers may seek alternatives that offer a more complete solution. For example, if your project management tool lacks integrations with other essential tools, your customers might move to competitors who provide these integrations.
Complex or unintuitive UX: Even the most feature-rich products can lose customers if the user experience isn't intuitive. A confusing or overly complicated interface forces users to waste time searching for basic functions, which can quickly lead to frustration.
Inconsistent performance: Frequent downtime or laggy interactions can quickly erode trust in your product. Businesses rely on SaaS products to run efficiently, and any performance issues can damage their experience.
Lack of value realization
Sometimes, customers leave not because the product is broken but because they don't clearly see the value it provides. This can happen when your product's benefits aren't well communicated or when you attract the wrong customer. In B2B SaaS, where buying decisions are often tied to ROI, a lack of visible impact can quickly lead to dissatisfaction.
Customers are much more likely to churn if they can't connect your product to a meaningful outcome like time saved, better performance, or measurable business growth. Even if the product works, if the results aren't clear, decision-makers may start questioning whether it's worth the cost.
Poor customer support
When customers have questions or problems, they want help quickly. In B2B, where time is money, slow replies, confusing answers, or no response at all can make customers frustrated. Research found that 80% of customers leave because of bad support.
Over time, this can make customers feel unimportant, especially if they have to keep repeating themselves or looking through unorganized help documents. Eventually, they may decide it's not worth the hassle and look for a company that gives them better support.
Financial challenges
Sometimes, customers churn not because of any product issues but because of financial constraints. When companies face tight budgets or economic downturns, they are often forced to make tough decisions about which services to keep and which to cut. If they don't see your product as an essential tool, it might be one of the first expenses they trim.
That's why it's important to demonstrate the value of your product from the get-go. By clearly showing how your product helps customers save time, optimize processes, or deliver measurable results, you can reinforce its importance and increase the likelihood that they'll retain it. The more integrated your product is into their workflow, the less likely they are to cancel, especially if they see it as an essential part of their business operations.
Losing key users inside the company
Many times, a company uses your product because one internal champion pushed for it - they liked it, saw the value, and got others on board. But if that person leaves or gets a new job, the rest of the team might not feel the same way.
The issue lies in the fact that without their constant influence, other users might not see the full value of the product, and they may not be as motivated to use it regularly. This can lead to disengagement and, ultimately, churn. Additionally, new personnel coming in might not immediately see the product's value or prioritize it in the same way as the original advocate.
5 Key tactics for reducing churn
The biggest improvements in reducing customer churn often come from experimentation, testing different approaches, and using real-world data to understand what works best for your business. Here are some proven methods that can help you get started:
Maintain product reliability
The reliability of your product plays a huge role in whether B2B customers stay or leave. Downtime, bugs, and sluggish performance often lead users to stop logging in without ever opening a support ticket.
Here's how to maintain optimal performance for your product.
Schedule regular product testing: Start by scheduling quarterly performance testing. This means simulating real-world conditions: user load, cross-device behavior, and edge cases your dev team might not consider day-to-day.
Transparency: Maintaining a public status page gives your customers real-time visibility into outages or incidents. Even if something goes wrong, users are likelier to trust a vendor who communicates openly than one who goes silent during issues.
Feedback system: Create a feedback system between your support and product teams. If support hears the same complaint repeatedly, the product team should be aware of it. When you fix something or add a requested feature, tell the users who asked. A simple "we heard you" can go a long way in keeping customers loyal.
Demonstrate clear value to your customers
Churn often starts when customers no longer see your product as essential. Your job is to make the value of your product clear, ongoing, and specific to each person who uses it.
A strong value communication flow often includes:
Tie your product to business results: Help customers see the tangible outcomes of using your product. Go beyond typical usage stats and show how your tool affects things they care about, like saving time, hitting KPIs, or improving efficiency. For example, "Automated processing saved your team 30 hours last week."
Ongoing value reminders: Set up check-ins, like quarterly reviews, product education emails, or feature recaps, that spotlight underused tools and recent improvements. You can also use in-app messages or reminders to show them the benefits of your product at the right time.
Give better customer support
You may have made a great product and sent helpful welcome emails, but if support is hard to find, users will get frustrated. That's why it's important to improve how you give help.
Here are a few ways companies strengthen their support experience:
In-app support: Add support inside your app, such as embedding a chat widget. This lets users get help quickly without leaving what they're doing. This makes support faster and more helpful and keeps users from quitting.
Multi-channel support: Customers should be able to interact with you from wherever they are. Live chat is ideal for quick issues, email works well for more detailed queries, and having a support option on social media channels like LinkedIn adds an extra layer of convenience.
Self-service options: A simple, searchable help center (or FAQ) can answer common questions so users can solve problems on their own. Consider adding an AI chatbot to further improve support.
Customer service enablement: To support your service team effectively, provide continuous training and the right resources. Create a knowledge base, offer troubleshooting guides, and establish clear workflows to ensure your team can handle any scenario efficiently.
Simplify and maintain the payment process
A complicated payment process can silently push customers away. Even if they love your product, friction during checkout, limited payment options, or failed transactions can lead to frustration, missed renewals, and, ultimately, churn.
Here's how to optimize the payment process:
Simplify the payment flow: Aim for a single-page checkout with only essential form fields and clear instructions. Use auto-fill functionality and, for returning customers, implement one-click payments.
Expand payment options: Offer a variety of payment methods to meet customer needs. Different businesses have different preferences, so provide options like credit cards, bank transfers, ACH, or PayPal. So, make sure you've the best business banking with your SaaS that provides everything your clients need.
Implement auto-renewal: To ensure no interruptions in service, offer auto-renewal as an option. This way, customers don't have to worry about manually renewing their subscriptions, reducing the risk of accidental cancellations due to missed payments or administrative oversight.
Encourage team-wide adoption
Team-wide adoption lowers the risk of churn caused by single-user dependency. When multiple people in a department use your product, it becomes embedded in the company's workflow and much harder to replace.
Strategies to encourage wider adoption include:
Simplify user invitations: Evaluate how easy it is for a single user to expand access to others. Make sure permissions are easy to assign and clearly explained.
Encourage collaboration: If your product supports multiple roles, such as admins, contributors, or viewers, ensure the features are accessible and intuitive.
Team-based onboarding: Offer team-based onboarding or training. This could include custom demos, role-specific walkthroughs, or even recorded sessions for busy departments. These sessions help internal champions get support from other stakeholders.
Final thoughts
Customer churn might not be something you can completely eliminate, but that doesn't mean you shouldn't keep an eye on it and minimize it as much as possible. To manage churn effectively, start by understanding its causes, whether that is poor UI, weak customer support, or pricing issues, and then implement the tactics that address these pain points.
Remember, the more you focus on creating great experiences and building strong relationships, the more likely your customers are to stay loyal, continue using your services, and even recommend you to others.
