reservation system for personal trainers

Personal trainers - whether fitness trainers or coaches focused on personal development - primarily sell their time and expertise. Every unbooked appointment is a loss, every no-show is frustrating, and every hour spent scheduling appointments by phone or through messages is time that could have been devoted to a client. An online reservation system brings order to a trainer's schedule while giving clients the convenience they have come to expect.

What you need to manage ...
  • Setting available time slots so clients can choose a time that suits them.
  • Tracking training packages - clients pay upfront for a block of sessions and then use their credit over time.
  • Accepting online payments for individual sessions and packages without having to handle cash or process transfers manually.
  • Automatic reminders before each session so clients arrive prepared and on time.
  • Managing different types of services - individual training, group sessions, online consultations, or gift vouchers for a one-hour training session.
  • Keeping client records and collaboration history clearly organized in one place.

For personal trainers, an online reservation system is not just a matter of convenience - it is a way to professionalize the entire approach to working with clients. A large part of a trainer's working day is often devoted to administration that, while necessary, provides no direct value - scheduling appointments, confirming payments, sending reminders, and looking up client records. A well-configured reservation system automates these routines - allowing trainers to actually train instead of spending the afternoon on the phone or answering messages. For clients, online reservations are a natural part of today's experience - they simply choose an available time, pay, and receive confirmation with all the details. No waiting for a response, no uncertainty about whether the time slot is actually available. The system can also automatically collect initial information during the reservation process - so the trainer knows in advance about the client's goals, health limitations, or previous experience. Instead of spending the introductory session asking questions, they can start training right away.

The economics of a personal trainer's work depend on filling as much paid time as possible. Training packages - blocks of ten or twenty sessions purchased in advance - benefit both parties. The trainer or coach is guaranteed payment upfront, while the client commits to a long-term working relationship. Training gift vouchers can also attract entirely new clients who might never have picked up the phone themselves - a partner, friend, or employer buys the voucher for them, and the client schedules the session independently, at their convenience and without pressure. Automated communication before and after each session - whether it is an appointment reminder, preparation instructions, or a short questionnaire after a completed session - helps trainers build relationships and maintain a professional image without additional manual work. And for trainers who offer group sessions or online workshops alongside individual training, having everything together on a single reservation page is a major advantage - with no need to manage multiple tools or coordinate different calendars.

Key features for personal trainers

An online reservation system for personal trainers covers the entire cycle, from selecting a time slot and making a payment to automated client communication and collaboration records. Whether you work one-on-one, lead group sessions, or offer online coaching, the system adapts to your services and saves you the time you currently spend organizing instead of training.

Punch cards and customer credit

Customers who use your services repeatedly and regularly will welcome an efficient way to pay for them, including a discount. Whether it's a punch card for a certain number of visits or a set value, or top-up credit that customers draw down, this feature has you covered.

Punch cards and customer credit

more in the documentation

Offer loyal customers a more convenient way to pay for repeat visits – a punch card for a set number of visits or value, or top-up customer credit.

The reenio system offers several ways to let customers pay for reservations based on a previously prepaid value, instead of individual direct payments.

Punch cards work as a special type of coupon with a set number of visits or a gradually drawn-down amount (credit-based punch card). Applying the punch card code adjusts the reservation price accordingly, either by subtracting a defined amount or applying a discount of up to 100%. These codes don't have to be tied to a specific registered customer account, so they can be used easily and flexibly. They can also be restricted to specific events, so you clearly define which offered activities a punch card can be used for and which not.

Customer credit, on the other hand, works as a virtual wallet linked to a registered and logged-in customer account. A customer can top up their credit themselves online via a payment gateway (potentially with a bonus), or you can top it up manually in the administration, for example when paying in cash at reception. A credit wallet can in principle also have an expiration set.

Both solutions can be used effectively together with online payments, where the whole process of purchasing punch cards or credit can be fully automated. There are many possibilities, and it always depends on your specific settings and how you think through how and under what rules these customer-loyalty tools will work for your particular type of business.

Event: Interval

This event type allows opening hours to be split into regular time slots. Customers book one or more consecutive time slots according to their own needs. One of the most widely used and most efficient event types.

Interval event type

more in the documentation

If you offer services in regular time slots (60 minutes, 90 minutes, etc.), this is the ideal event type, offering a simple and clear booking process.

The Interval event type lets you define a time range within a single day and split it into smaller, regular chunks. On the reservation page, a customer chooses these specific time slots, which can also follow on from one another, extending their reservation according to the defined rules.

This event type is typically suitable for sports facilities and sports complexes, consulting and advisory services, wellness, or a sauna.

Notifications

Keeping customers informed is one of the key functions of any system. The ability to send a customer confirmation of a reservation being created, cancelled, or paid, or a reminder about it, is thus an integral part of the reenio system.

The reservation system can automatically inform customers, as well as admins and employees, about what's happening around reservations – you can set up system notifications according to your needs and the way you operate.

System notifications are automatic e-mails and SMS messages that the system sends on behalf of your reservation page without any further action on your part. These include confirmation of a successful reservation, confirmation of cancellation, confirmation of payment, reservation approval, a PDF with reservation codes, a reminder of an upcoming event, and more.

For each event type in the settings, you determine which channel it should be sent through – e-mail, SMS, or both – and, if relevant, how far in advance. For example, a reminder about an upcoming event can be sent 24 hours and also 3 hours in advance. Sending, of course, assumes you have the corresponding customer contact details available.

  • For customers

    All communication and information from the system to the customer, including a reminder so a reservation doesn't lapse unnecessarily.

  • For administrators

    To provide a basic overview of what's happening in the system without needing to constantly check and log into the administration.

  • For employees

    Ideal when a specific employee needs to be notified that a reservation for their services has been made and they need to plan for it.

Unlike custom messages, these are messages with a fixed, predefined content reflecting reservation information – their content or form cannot be freely edited, only when and to whom they are sent can be configured.

Multi-language support

The system supports several languages, both in the administration and on the reservation page. This lets you tailor the booking process for customers from different countries, in different languages at the same time.

Multi-language support

more in the documentation

Reach and communicate with your customers in their own language, whether they're booking from your home country or from abroad – the reservation page and the entire administration can run in multiple language versions at the same time. 4 supported languages are available for the administration, and 7 languages are available for localizing the reservation page.

Custom content that you enter into the system yourself (terms and conditions, resource descriptions, event names, homepage information, etc.) needs to be translated and provided by you. The system offers a clear way to manage information across multiple languages.

Online payments

Being able to pay for a reserved service through an online payment gateway is now the standard. Customers today are used to paying quickly and securely in online shops and expect the same comfort when booking or ordering services online.

Online payments

more in the documentation

Let customers pay for their reservation or tickets online right away, before the service is provided – faster, more convenient, and with the certainty that the reservation will be paid, and therefore used.

The reenio system allows you to require prepayment as part of the booking process, so a customer's reservation only becomes valid once paid. You decide yourself whether online payment is mandatory, or whether you leave it up to the customer to pay on site. With mandatory payment, you can set a deadline by which a new reservation must be paid, otherwise it is automatically cancelled and the slot is released for another customer.

For online payments you can choose from several supported payment gateways. The reservation system then handles the technical connection and communication with the chosen gateway, but all business and formal matters are handled directly with the payment gateway provider – you keep the money you receive under your own control, in your own merchant account.

  • GoPay

    An online payment gateway offering a wide range of payment methods, from card payments to fast bank transfers, Apple Pay, or Google Pay.

  • Comgate

    Another Czech payment gateway that also operates in other European countries. Its payment methods vary and cover common needs.

  • Stripe

    A global payment gateway that is becoming increasingly popular. It offers fast integration and approval, so you can start accepting payments within minutes.

  • Bank transfer

    A special type of payment method where the reservation system itself can generate a QR code for payment and then automatically verify and match received payments.

After a successful payment, the system automatically marks the reservation as paid and generates and sends the customer a payment document. The reenio system offers a wide range of options and features for working with payments, including exports, refunds, and more. However, it should be noted that reenio itself is not an accounting system.

Gift coupons

A discount for new and loyal customers, a gift for using a specific service, or a gift of a certain value? The gift coupon feature can handle all of this, offering not only flexible coupon types but also direct online sales of them.

Offer your customers gift coupons for your services, and at the same time let them buy gift coupons online – the customer immediately receives their coupon by e-mail and can give it as a gift or use it right away.

Gift coupons are part of the broader discount coupon and punch card functionality, with a similar approach and possible uses for all these tools. You create a coupon with predefined parameters – a set validity period, discount amount, or value – and assign it to specific events it can be applied to (so you can have different coupons for different service offerings, or events that don't accept coupons at all). The customer then receives a coupon code, either directly from you or through an online purchase.

  • One-off redeemable amount

    A classic coupon with a fixed monetary value, typically for one-off use as a gift.

  • Percentage discount

    A discount coupon for a proportional amount, typically suitable for giving to new customers or as a punch card, etc.

  • Gradually redeemable amount

    The coupon has a certain monetary value which is used up gradually – a form of virtual wallet.

  • No discount

    A type of coupon that doesn't adjust the price at all, but can be used, for example, to restrict reservations to a limited group of customers.

For genuine gift coupons, the ability to create your own design (PDF) is important, reflecting not just your visual style and intended use, but also allowing space for a dedication and so on.

Customer database

An overview of your customers, their details, and history is key to any business. The customer database not only records this data but also provides tools for communication, data export, and meeting GDPR requirements.

Customer database

more in the documentation

Keep a clear customer database with a reservation history and a whole range of related tools. The reenio system automatically builds the customer database based on reservations made or direct registration. A registered customer gains the ability to log in and manage their reservations directly within the reservation page. If customer credit is used, they can see their balance within their account and top it up online.

Depending on your settings, a reservation can also be allowed without registration, simply by entering an e-mail address or phone number, which is especially suitable where you don't expect one specific customer to use the reservation system regularly and often.

A well-maintained, extensive customer database is an important marketing tool. The system offers the option of bulk sending e-mail or SMS messages, which is useful for reaching customers with a new offer, a discount campaign, but also operational information or as part of crisis management.

The customer database naturally contains personal data, which today requires a certain approach to how it's handled and protected. The reservation system allows you to set up automatic deletion of personal data after a chosen period, and also keeps track of customer requests to have their data deleted. This makes it easier to meet GDPR requirements in line with the rules defined for your particular business.

If you need to import a customer database from another system or a manually maintained spreadsheet, that's no problem – an existing customer list can be easily and smartly imported into the reenio system.

Event: One single event

The easiest event type to set up and use, offering a booking for a specific, fixed time from and to, including an optional capacity limit. A customer always books the entire listed event.

Event: One single event

more in the documentation

Offer customers a reservation for a fixed time slot with a limited capacity – ideal wherever more than one person needs to be able to attend an event, but not more than you're able to serve.

With the Full single event type, a customer always books the whole event as set, i.e. a fixed time slot from – to, with no option to choose a custom time. This is typically an event with a higher capacity, taking place at a fixed time – suitable for sports events and lessons, seminars, lectures, concerts, exhibition openings, one-off courses, workshops, or tours.

For this type you can also enable a so-called waiting list, where a customer can still express interest in booking even after all available capacity has been used up. This event type also supports creating recurring reservations and supports online events.

Google Calendar sync

Having a clear overview in a calendar is an important part of organizing time, especially with online reservations. Thanks to synchronization, you can keep your Google Calendar up to date, and conversely block off time within the range of events on offer.

Google Calendar sync

more in the documentation

Calendar synchronization lets you connect the reenio system with an external calendar. This is typically a connection with Google Calendar, and is set up simply by logging in with your Google account and granting access.

Reservations created in the reenio system will appear in your calendar, but the reverse doesn't happen – reservations aren't created from events in your Google Calendar (the booking process is complex enough that a calendar event alone isn't sufficient). In the other direction, i.e. from Google Calendar into the reenio system, synchronization is therefore only limited – events can be synchronized as time blocks, so that no new reservation can be created for that particular date and time.
