Building Better Booking Systems

• Behavioral frictions in booking systems contribute to high abandonment and no-shows, highlighting opportunities to improve the user experience and boost performance.
• Adaptive choice architecture condenses complex information and streamlines difficult decisions, reducing the cognitive load on users and minimizing the risk of choice paralysis.
• Timely prompts and nudges throughout the booking process make the immediate benefits of booking more tangible, offsetting upfront effort and high perceived costs.
• Commitment devices and social norms encourage users to follow through on bookings, reducing the intention-action gap that contributes to costly no-shows.

Booking systems have become integral to everyday life. They help us book medical appointments, flights, hotel rooms, restaurant reservations, concert tickets, classes, and more. Thanks to their convenience, these tools have a significant impact on a wide range of industries. In healthcare, online bookings improve provider efficiency, boost patient satisfaction, and optimize resource utilization.¹ In travel and tourism, online bookings are a significant source of revenue. The global online travel industry—valued at $512.5 billion in 2023—is projected to surpass $1 trillion within the next decade, with online bookings expected to account for 75% of total travel revenue by 2029.² Small businesses such as wellness studios, salons, pet groomers, veterinarians, hairdressers, consultancies, and contractors also find these tools incredibly useful for drumming up business and saving time on customer service.

However, this promising shift toward digital self-service is not entirely seamless. While booking systems are undeniably convenient, they show high rates of abandonment.² Users often make it part of the way through the booking process and exit the funnel early, either procrastinating the process or giving up altogether. Data from the hospitality industry estimates that revenue losses from abandoned bookings amount to $10 billion over the course of a full year.³ 

Even worse, completed bookings that result in no-shows can lead to substantial costs for organizations, whether it’s empty seats in fine dining establishments, unused government service slots, or missed doctor’s appointments. In healthcare systems around the world, individual physicians and care networks are on the hook for around $200 for every hour of no-shows.⁴ Other industries struggle with similar absentees. Failures in booking systems can also create operational bottlenecks, like when a customer makes a mistake during booking and requests corrections, increasing customer support needs.⁵ 

From a behavioral science perspective, these challenges are not surprising. Booking systems require consumers to make complex and costly decisions, often during periods of uncertainty and long before they experience the value of the booking—conditions which are not conducive to careful, confident decision-making. When platforms are difficult to navigate, options are too numerous, and bookings are made to feel more like loose plans than true commitments, these tools can suffer from high rates of abandonment, no-shows, and customer service calls. Let’s take a closer look at these challenges and explore some behavioral design opportunities that can make booking systems better for everyone.

One of the most common deterrents for those using online booking systems is complexity. When it comes to booking healthcare, ease of use is directly related to a user’s willingness to self-schedule appointments.⁶ The same goes for hotel bookings, where the number of choices provided to travelers has a significant influence on their decision confidence.⁷ Whether it’s too much information, too many options, or a confusing interface, these complexities tax users’ mental bandwidth and derail their decision-making processes, causing them to abandon bookings or make choices they later regret.

Why More is Not Always Better

More choices don’t always make booking easier for users. Providing more time slots, bundles, upgrades, or add-ons might give users the freedom to create bookings that align with their needs, but human brains have a limited capacity to process information. Giving people too many options leads to a form of decision fatigue called choice overload or choice paralysis, where decisions become so difficult that people often shy away from them altogether. As a result, users might put off their decisions or make choices driven by convenience or impulse rather than a careful evaluation of their available options. Even when users sift through their numerous options and complete a booking, the paradox of choice tells us that people feel less satisfied with their decisions when they have to choose between too many options.⁷ This could contribute to higher cancellation rates and customer service requests.

Poor Interface Design Creates Additional Cognitive Load

Many online booking systems also suffer from user experience (UX) design flaws that increase cognitive load, making users less confident in their decisions. Confusing user interface (UI) layouts, unclear navigation, and even seemingly small frictions like slow load times and multi-page forms can increase demand on users’ decision-making resources, increasing the likelihood that they make suboptimal choices—or no choices at all. 

While travel agencies and digital service providers have made booking UIs fairly frictionless from a design perspective, healthcare has long lagged behind in adopting user-friendly self-scheduling systems.⁶ Patients often express concerns about the usability of these tools, especially among those with limited computer skills, who often prefer verbal communications.⁸ When booking systems are unintuitive, users can have a hard time finding the time slots they need, understanding pricing, coordinating services, managing overlapping reservations, or even trusting that their booking has been successfully recorded.

Choice architecture involves crafting decision-making environments—such as online booking systems— to subtly influence the choices people make without restricting their options. On booking platforms, altering how options and information are displayed can go a long way toward improving the user experience and simplifying complex decisions. This might mean highlighting recommended options, replacing drop-down menus with visual calendars, or collapsing multi-page forms into scrollable pages with progress indicators. Progressive disclosure can further reduce cognitive load by showing users only the most essential information and revealing additional details as needed or upon user request. 

Thanks to machine learning technology, online booking systems can take static choice architecture one step further, using algorithms to filter and present options that are more relevant to individual users—or even update based on environmental factors like the weather or time of day. This creates an adaptive choice environment that helps users quickly find the options they need. 

Personalized Filtering and Ranking

Many booking platforms, such as online travel agencies, allow users to filter and rank their available choices based on their needs. This has been found to reduce choice overload when users are facing a large number of options.⁷ Today, platforms are starting to explore personalized filtering, driven by artificial intelligence (AI), to automatically prioritize options that are likely to appeal to individual users. For example, outpatient scheduling platforms could dynamically learn from user behavior to present commonly booked timeslots or preferred physicians, helping patients make better booking decisions while minimizing the amount of manual work they need to do.⁹ 

Smart Recommendations and Defaults

Besides filtering and ranking options, predictive models can also set defaults for users to gently guide them toward optimal decisions without forcing them to process unnecessary information. Machine learning models in travel booking systems could account for factors like weather, seasonal events, and user preferences, offering hyper-personalized recommendations to improve user satisfaction. Recent research shows that these models are highly accurate at forecasting user behavior and can significantly improve how people interact with booking platforms.¹⁰ Predicting what people need and presenting these options as the default—by pre-selecting them for the user—could help reduce abandonment and improve booking follow-through.

Importantly, filtering systems and defaults reduce cognitive load while still preserving individual autonomy, ensuring users maintain a sense of control over their options. Allowing users to select alternatives or make choices outside of their usual patterns is crucial for building trust and minimizing potential frustration. This is why adaptive choice architecture strategies are preferable to solutions that simply strip back the user's options or outright make decisions for them.

Another common friction point in booking systems is the cost-benefit analysis. When making bookings, users are often confronted with upfront costs, such as hotel room deposits, ticket fees, class registration payments, and membership dues. Even when bookings lack a monetary fee, navigating the platform still costs time and effort. Since these costs won’t pay off for the user until a future date, the reward can seem too distant to be sufficiently motivating. Due to a cognitive tendency called present bias, people tend to overweight the immediate costs of an action while undervaluing future gains. As a result, users often delay making high-effort or high-cost bookings, even when they’re anticipating future benefits—like the excitement of a trip abroad or the peace of mind that comes with a routine visit to the doctor. 

Temporal Discounting Leads to Booking Procrastination

Present bias is a form of temporal discounting, a tendency to value future rewards less than immediate rewards. Generally, the further rewards exist in the future, the less valuable they seem. Studies show a positive correlation between how much people discount future rewards and their tendency to procrastinate.¹¹ When it comes to booking systems, delayed incentives can derail motivation, causing users to put off bookings, especially in the face of heavy upfront costs. 

Hidden fees or unclear trade-offs can exacerbate the impact of temporal discounting on users’ motivation to complete online bookings. Drip pricing—a type of dark pattern that slowly adds fees throughout the booking process—can increase the perceived upfront cost of completing bookings. While drip pricing sometimes increases conversions, users frequently abandon bookings with excessive added fees because they decrease the perceived value of the transaction. This is important because people are more likely to complete bookings when the perceived value is high.¹³

Lack of Trust Cues Creates Perceived Risks

Beyond high effort and hidden fees, perceived risks in booking systems can also make upfront costs feel too high to justify the distant rewards. When users are worried about losing money or giving up their personal information, their attention naturally shifts away from the future payoff and toward the risks involved in the transaction. For example, a lack of perceived security and privacy has a substantial influence on users’ intentions to abandon online hotel reservations.¹⁴ Because people are naturally averse to ambiguity and potential risk, uncertainty about security, privacy, and refund policies can lead to mistrust and abandonment. This issue is even more significant in healthcare portals, where medical appointments often request sensitive information from patients during online bookings. In fact, a lack of trust in the internet is a key barrier to adopting medical self-booking systems on the patient side.⁸

When users abandon bookings because future rewards feel distant and upfront costs feel immediate, well-timed nudges can help bring those future benefits psychologically closer. By highlighting near-term benefits, framing costs transparently, and incorporating trust cues, booking systems can reduce perceived costs and encourage earlier commitments from users.

Introduce Timely Nudges to Highlight Opportunities

Nudges are subtle design interventions intended to steer people toward behaviors that are in their best interest. In online booking systems, timely nudges can encourage users to focus on the near-term benefits of completing a booking, helping them overcome the upfront effort or monetary costs involved. Nudges could take the form of simple statements accompanying high-friction points in booking, such as pages asking for payment details or personal information. Statements like “Book now to secure your preferred doctor,” “Complete your reservation to avoid peak-season travel rates,” or “Schedule your salon appointment to claim your time slot” could be enough to increase the perceived value of bookings.

One study exploring the effects of nudge messaging on medical appointment scheduling included the call-to-action, “Schedule today to secure your preferred time!”²⁴ Compared with standard reminders, these nudge messages were associated with more appointments booked via the patient portal, demonstrating that simply modifying the message in an appointment reminder can have a significant impact on booking behavior.

Importantly, nudges shouldn’t make users panic and rush into unplanned decisions. Rather, they should remind users of the tangible benefits they gain by completing the booking now, adding immediate rewards without creating unnecessary pressure.

Frame Costs to Prevent Last-Minute Abandonment

Cost framing can also be effective in increasing the perceived value of online bookings, especially among users who put off bookings to track down the best price. Showing the total cost from the outset—and stating that all fees are already included—can increase consumer confidence and reduce the hidden fee shock that drives last-minute abandonment. Beyond this, many online travel agencies are moving toward automated rate match tools to guarantee competitive prices so customers feel confident booking without shopping around. The Daeyoung Seoul Hotel in Korea, for example, uses an automatic rate match program to ensure travelers always see the best possible rate for rooms, helping build traveler trust.¹⁵ Hotels that use these tools typically see room bookings rise by about 15%. 

Incorporate Trust Cues Throughout Booking

Transparent pricing is just one type of trust cue that can make users more comfortable completing their online bookings. Other ways to signal trust include offering flexible ticketing options and highlighting cancellation and refund policies before users commit. For example, The Real Mary King's Close, a historic tour in Edinburgh, Scotland, offers a “flexi-ticket” that can be changed before arrival, adding flexibility to encourage pre-booking.¹⁶ Similarly, pages requesting payment or personal information can include verified payment badges, security icons, and personal privacy notices to reassure users. Credibility cues and trust badges like these play a powerful role in influencing a consumer’s perception of risk and purchase behavior.¹⁷

Online reviews can also have a significant effect on users’ trust toward organizations offering online bookings.¹³ Consumer reviews are a valuable form of social proof that communicate information about what others are doing, which can help nudge people toward desired actions when they’re facing uncertainty. Based on this effect, displaying positive reviews throughout the booking process can help increase trust, boosting users’ willingness to complete their bookings.

While online bookings can help reduce no-shows over traditional booking methods, missed appointments and reservations remain a significant issue. In industries that rely on high-volume bookings, like air travel, healthcare, and government services, no-shows frequently lead to lost revenue and underused resources. Research shows that basic reminders only have modest effects, suggesting that there’s more to no-shows than simply forgetting about appointments.¹⁸ Let’s explore some of the deeper behavioral barriers that can prevent people from following through after making an online booking.

Limited Self-Management Support Reduces Self-Efficacy

Scheduling conflicts are a fact of daily life that force people to choose between competing priorities, and pre-booked appointments don’t always top that list. Unfortunately, many booking systems stop serving users at the point of their reservation, failing to provide follow-up support to help users manage their reservations or make cancellations. When users encounter friction when trying to cancel or change a booking, they lose their sense of control. This lack of self-efficacy often leads to decision postponement and can make it easier for users to psychologically disengage from actions.¹⁹ Even the prospect of making a quick phone call can create enough friction to prevent people from bothering with a cancellation, leading to unexplained absences. 

The Intention-Action Gap in Online Booking

Even when users have tools to manage their bookings, another challenge often gets in the way: the intention-action gap between what people intend to do and what they actually do. When most people make online bookings, they have every intention of following through on their commitment, but in reality, intention doesn’t guarantee action. Sometimes, people simply cannot follow through on their bookings because they’re facing unexpected transportation issues or scheduling conflicts. Other times, barriers are psychological. People might feel anxious about a doctor’s appointment, decide their dog doesn’t really need grooming, or simply lack the motivation to drive to the insurance office. When barriers are psychological rather than a simple case of forgetting, generic appointment reminders are not likely to close the intention-action gap. 

Without commitment devices to encourage people to stick to their intentions, they can dismiss them without feeling much psychological resistance. People feel even less obligated to follow through when it seems like no one else is affected by their absence. Often, this is because customers are simply not aware of the impact they can have by missing an appointment, instead feeling a diffusion of responsibility where they are not personally accountable for the effects of their absence.

Building better booking systems isn’t just about encouraging bookings, but ensuring users actually carry out their commitments. This is the value of follow-up support. By empowering users to manage their bookings, employing commitment devices to encourage adherence, and using social reinforcement to motivate action, booking systems can help organizations reduce no-shows and keep everything running smoothly.

Self-Serve Booking Management Increases Self-Efficacy

The best booking systems give users complete control over their appointments. They allow users to sync bookings with their personal calendars, helping them juggle appointments, manage conflicting priorities, and increase their sense of control over busy schedules. They also make it seamless for users to manage or cancel appointments. Online appointment management is one of the key advantages of online booking systems—people are more likely to reschedule or cancel appointments when they’re able to do so online, reducing unexplained no-shows more than offline bookings.¹ As such, ensuring appointment management options are salient and frictionless is crucial for empowering users to maintain control over their commitments.

Commitment Devices Impose a Future Cost for No-Shows

Commitment devices are ideal for bridging the gap between intention and action. These precommitments allow users to willingly restrict their future options or lock themselves into a course of action by establishing undesirable consequences for failing to follow through. Having users pay a deposit or imposing basic no-show penalties can serve as effective commitment devices. Precommitments can also impose reputational penalties or social costs. For example, encouraging users to make bookings alongside other people encourages attendance by increasing accountability. This might not work for all types of bookings, but it can be useful for fitness classes or other events where failing to show up would directly impact others.

Some businesses are understandably hesitant about introducing penalties for missed bookings. For example, fine dining establishments find that cancellation policies hurt the customer experience because they're often perceived as risky or unfair.²⁰ In situations like these, lenient policies tend to be better than strict ones because they feel safer and less salient to the consumer. Even better, research suggests that building awareness around the negative impact of no-shows can soften the drawbacks of cancellation policies on customers’ perceptions of fairness and willingness to book.²⁰ For example, diners are less likely to view a strict cancellation policy as unfair when they understand how missed reservations affect the restaurant. A simple message at the time of booking—such as, “missed reservations lead to food waste and lost income for our staff”—can help justify a cancellation fee or reservation deposit, making the policy feel more reasonable.

Social Reinforcements Highlight Norms and Impacts

One of the best ways to reduce no-shows is to tell people how their lack of commitment can affect others. In the fine dining industry, awareness campaigns educating consumers about the negative repercussions of no-shows have been effective at fostering a sense of accountability and encouraging people to follow through on their reservations.²⁰ While campaigns might exist outside of booking platforms, system-integrated reminders can incorporate similar interventions to reduce no-shows. For example, the Behavioral Insights Team found that text reminders highlighting the specific cost of a missed appointment to the healthcare system reduced no-show rates by 32%.²¹ 

Similarly, social norm interventions also appear more effective at reducing no-shows than simple reminder messages. For example, in one study, reminders included the message “9 out of 10 people attend” to reinforce the idea that following through on bookings is normal and expected.²² By highlighting social norms around appointment attendance and the specific impacts of individual no-shows, booking reminders are more likely to resonate and drive people to act.

When it comes to building better booking systems using practical insights from behavioral science, a few key caveats stand out. First, it’s important to acknowledge that most of the studies in this area come from North America and Western Europe. Less research is available from regions like Asia, Latin America, and Africa, where organizations are increasingly adopting digital booking tools. Research has revealed significant cultural differences in consumer online purchase behavior, highlighting how different norms and expectations can impact how users perceive the usability, trust, perceived risk, and social relevance of online platforms and related nudges.²³ Due to these unpredictable differences, it’s crucial to test interventions in specific contexts before applying them to a wider audience.

It’s also important to keep in mind that not all instances of booking abandonment are due to frictions in the booking system. Many times, consumers are simply shopping around, comparing prices, or exploring their available options without intending to book right away. In these cases, abandonment doesn’t necessarily reflect a weakness of the system, so there are limits to how much interventions can improve follow-through. Improving booking systems is more about capturing booking intent than reducing abandonment from exploratory browsing behavior. That said, these platforms can make it easier for users to browse and resume their booking later. Features that allow users to save their search content, hold available timeslots for a short period, or compare options from other providers can reduce decision pressure while ensuring a seamless return when they are ready to book.

Finally, as with all interventions intended to shape human behavior, ethics and transparency are also crucial when building booking systems that minimize abandonment and no-shows. Interventions that steer behavior can sometimes fall into manipulative territory, especially when they encourage the consumer to act against their best interest. Urgency cues, profit-maximizing defaults, predatory cancellation fees, and guilt-driven social norm tactics like confirmshaming can hurt the user experience. Respecting user autonomy and empowering them to make better decisions for themselves is crucial for building booking systems with a positive, sustainable impact.

While convenient and incredibly valuable, many booking systems create unnecessary friction, leading to lost revenue, wasted resources, and poor user experiences. By acknowledging predictable behavioral patterns like choice overload, present bias, and the intention-action gap, organizations that rely on these booking systems can ensure they’re designed with human psychology in mind. This means using adaptive choice architecture to streamline the decision-making process, presenting timely nudges to make the benefits of booking feel more immediate, and empowering users to follow through on their bookings with commitment devices and social reinforcements.

These human-centric improvements aren’t just a matter of making booking more convenient. Booking systems affect how people access essential services around the world, from healthcare and government services to transportation, travel, and entertainment. Building systems that accommodate human quirks and behavioral patterns ensures that everyone can access and benefit from these tools. Simplifying decisions, building trust, and reducing no-shows can have ripple effects on a global scale—think fewer wasted resources, more efficient service delivery, and equitable access to online bookings in industries moving away from traditional offline methods.

Dancing to the Tunes of a Choice Architect

Many of our decisions are subtly shaped by intentional elements of choice architecture. In this article, we explore some of the most common nudges intended to steer consumer decisions one way or another, from manipulative tactics designed to maximize company profits to more ethical applications that empower consumers to make better decisions.

User Journey Map

Whether related to healthcare, travel, or entertainment, booking systems are a critical phase in the user journey. Mapping the user journey is crucial for making improvements to these systems. By identifying frictions that are not always obvious when looking at a system from a purely technical standpoint, user journey mapping helps designers uncover potential issues from the perspective of the end-user.
