How to make online booking easier to use for everyone

A customer has found the right appointment. They choose a time, fill in their details, and press “Book.” Then the form says something went wrong, but it does not say which field needs attention. The slot disappears while they try to recover. A booking page can look polished and still make a routine task hard to finish.

The useful first step is to complete a real booking journey yourself without a mouse, then repeat it on a phone and with the page enlarged. Follow the whole path: find the booking link, choose a service and time, enter details, correct a mistake, and read the confirmation. Record where you get stuck. Fix the barriers that prevent completion before polishing minor visual details.

This matters beyond a theoretical checklist. In the Canadian Survey on Disability, 2022, 11.1% of people with disabilities aged 15 and over in Canada reported a barrier related to online booking for appointments, services, or reservations because of their condition at least sometimes in the preceding 12 months. The survey covers people living in private dwellings and asks about online booking broadly. It does not measure your website, your customers, or how many bookings a redesign would recover. It also does not identify which part of a booking journey caused each reported barrier.

Start with the entire task, not just the form

Write down the route a customer actually takes. For a salon, that might begin on a service page and end with an appointment confirmation. For a venue, it might include a date picker, guest count, deposit, and email receipt. A good test includes every step and the messages between steps.

Use a test booking or a safe staging environment so you do not take a real appointment slot. Note the device, browser, and point of failure. Ask a colleague unfamiliar with the site to try the same journey and say where they expected to go next. This is a usability check, not a claim of accessibility compliance.

The W3C’s preliminary accessibility checks offer a useful starting list: page structure, keyboard access, visible focus, forms, labels, errors, and text alternatives. They are explicitly a first review, not a complete evaluation. Your booking provider’s embedded widget, payment step, and confirmation email are part of the customer’s experience too, even when another company supplies them.

Try booking with a keyboard

Put the mouse aside. Use the Tab key to move forward through links, buttons, fields, calendar controls, and the submit button; use Shift and Tab to move back. Look for a visible focus indicator so you can tell which control will respond. Test that a date picker or service menu can be opened, navigated, and closed without trapping you. Check whether the focus moves in a sensible order after an error or a new step appears. The W3C keyboard check explains what to observe.

Common trouble spots are custom calendars that only react to clicks, a pop-up whose close button cannot be reached, and a disabled-looking button that gives no explanation. If a third-party booking tool fails here, report the exact step to the vendor and ask for a fix or an accessible alternative. A telephone option can help someone complete a booking while the issue is being repaired, but it should not become an excuse to leave the online barrier in place.

Make every field understandable before and after an error

Look at each field without relying on placeholder text. Is there a visible label that stays on screen after someone starts typing? Does “Phone number” say whether it is optional? If you require a format, explain it before the customer submits. The W3C forms tutorial recommends clear labels, instructions, validation, and feedback; its label guidance explains why the visible label should also be associated with the control in the page code.

Then deliberately make mistakes: leave a required field empty, enter an invalid email address, and change an earlier selection. Does the response name the field, explain what is wrong, and tell you how to fix it? Can you find the message with a keyboard or screen reader? Do the other entries remain in place? The W3C guidance on error notifications recommends messages that identify the field and provide a clear correction. A vague “Invalid input” or red outline alone leaves the customer guessing.

For example, if a date is unavailable, “Choose another time for this service” is more useful than silently clearing the selection. The exact wording should match what your booking system actually knows. Do not say a slot is reserved until the system has confirmed it.

Check the page at phone size and with larger text

A phone layout is more than a narrow desktop layout. Try the journey with the on-screen keyboard open. Can you still see the field label, current selection, error, and next action? Can you scroll to a calendar’s controls without accidentally changing the date? Enlarge the page and check whether content overlaps, disappears, or requires awkward sideways scrolling. The W3C preliminary checks include text resizing and contrast as part of a first review.

Read the page as if you know nothing about the business. Service names should explain what is included; duration and location should appear before someone commits. If the booking takes multiple screens, make the current step and the way back clear. Ask only for information needed to make and manage the appointment. Each extra field is another place where a customer may have to interpret instructions or recover from an error.

Confirm what happened and provide a recovery path

The final screen should state whether the booking succeeded, what was booked, when and where it is, and what happens next. If a confirmation email is part of your process, check that it arrives and contains the same essentials in readable text. If payment is involved, make clear whether the card was charged, merely authorized, or not processed. Never show a success message before the booking system has recorded the appointment.

Also try a failed submission. Does the page preserve what the customer entered? Can they retry without guessing whether a booking already exists? If the answer depends on an integration, test that integration rather than assuming the visible page tells the whole story. These checks protect the customer from duplicate attempts and give your team a clearer problem report when something breaks.

Decide what to fix first and when to ask for help

Group findings by their effect on completion. A calendar that cannot be used from a keyboard or an error that cannot be found needs attention before a minor wording preference. Record the page, device, steps to reproduce, expected result, and actual result. That gives a developer or booking vendor something concrete to repair and retest.

Automated scanners can flag some problems, but the W3C notes that some checks require manual review. A clean scan does not prove that a person can finish a booking. When the journey includes custom controls, payments, or several connected systems, a specialist can inspect the code, test assistive technology, and coordinate fixes across providers. The owner still has an essential role: deciding what the service means, which details are necessary, and what confirmation should promise.

Making booking easier to use is an ongoing product task. Recheck the journey after changes to services, forms, widgets, or payment providers. If you are planning a new booking experience or need help untangling an existing one, tell Red Comet about the website or workflow you want to improve.
