reservation system for
your business

Connect the reservation system to other applications, smart devices, or automation processes according to your own needs, using the API (Application Programming Interface).

Being able to use the API interface brings a completely new perspective on how you can work with the data managed and provided by the reservation system. Using HTTP-based queries, you can retrieve specific data about reservations, customer overviews, accounting documents, code lists, and more.

Another important element in this regard is so-called Webhooks. These are notifications that can notify any external system, based on an event that has occurred, that a new reservation has been made, that a payment has been received, and so on. Combining Webhook notifications with subsequently retrieving data via the API can result in a comprehensive implementation of your own data-processing logic.

So if you need to build your own statistics dashboards, control lighting in a hall based on ongoing reservations, turn on sauna heating, or communicate with a smart lock, and so on, then using the API offered by the reservation system is essential. A typical use is also a direct connection to automation services such as Make or Home Assistant. What data and methods the API provides (mostly access to data) is described in detail 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.

Offer customers the option to save their ticket, reservation, or coupon directly to their phone, in an app they already know and use – Apple Wallet or Google Wallet.

The reenio system lets customers add the QR code for a reservation or ticket directly to their Apple or Google system wallet, so the customer doesn't need to look up a confirmation e-mail or print a document – the code is saved right on their phone, where they can easily find it when they arrive.

The same option can also be used with coupons – meaning QR codes for gift coupons, discount codes, and punch cards. For a coupon that's drawn down gradually, this solution has one huge advantage: the customer can see their current balance directly in their phone's wallet.

For the customer, this is primarily about convenience and a lower risk of losing or forgetting a ticket or coupon – for you, it means a somewhat smoother and faster check-in process for tickets and coupons.

Tailor the reservation system to your business – whether you run a sports facility, a beauty salon, a rental business, or organize educational courses, the system can flexibly respond to the various needs and ideas linked to your particular type of business. Of course, it's still a universal cloud system rather than a custom-built solution, so some very specific ideas about how it should work or look might not actually be achievable.

The system offers a wide range of settings that make it easier to tailor booking to your specific customers and business. The foundation of this flexibility is the different event types (Full single event, Intervals, Full sequence, Any time, Multi-day, Coupon, Seat reservation), from which you can choose the most suitable one – from one-off workshops, through hourly rentals of sports facilities, to multi-day stays or selling event tickets.

Building on this foundation is a whole range of further settings that let you fine-tune the process further: custom booking forms for collecting specific data, various types of prices and discounts, online payments and payment by credit, reservation approval, waiting lists, collision protection between resources, or automated communication using system and custom messages. Thanks to user roles, you can also involve your whole team with correctly set permissions, and connect the reservation system to other systems as needed via the API or webhooks.

So the system grows together with your business – from a simple setup with minimal configuration, all the way to a comprehensive solution using most of the available features at once.

Easily get data about reservations and customers out of the reenio system, and then work with it in Excel, using AI, or use it for importing into other systems, for example for e-mail marketing.

Overviews of reservations and customers can be easily exported to Excel at any time, including data from your own custom booking and registration forms.

Besides a simple data export, the reservation system can also be connected to other systems using the API or webhooks, letting you pass data programmatically and in real time, as well as work with it at the level of its data structure.

Deliver important information straight to a customer's phone, even in cases where an e-mail message isn't enough for various reasons – reservation confirmation, a reminder before an event, or instructions on how to use the service.

SMS messages are available in the system both as system notifications and as custom messages with any text you like. These can then be automatic, sent in connection with some event, or sent manually directly from a specific customer's detail page, or in bulk to multiple customers at once. SMS messages are limited by their length and what can be communicated, but even so play an important role in keeping customers informed.

An interesting option is using SMS messages for further functionality. This includes verifying a customer's phone number during registration or when creating a new reservation, or as a technical communication channel – for controlling a device using a predefined SMS text, e.g. turning on the sauna heater before the start of a reservation.

A reservation in the reenio system doesn't have to mean just a booked slot in a calendar – it can also mean a ticket. It's just a different way of looking at what you're offering customers, what they're buying, and how the whole process then unfolds.

Every reservation carries everything you'd expect from a ticket – a unique code, a QR code for quick check-in, and information about the time and exactly what it can be used for. From this perspective, selling tickets is a fundamental way of using the reservation system. A ticket is often understood as a document that, for example, matches the visual identity of an event and also contains additional information. All of this can also be provided in the reenio system, where you can create your own design for the reservation confirmation = the look and content of the ticket.

The customer receives their ticket by e-mail right after payment, can save it to their Apple or Google Wallet, and you simply scan it with the mobile app at the entrance. If you want to sell tickets for events, it's really nothing more than a reservation with online payment and a custom confirmation design.

Unlike other event types, the Coupon event type doesn't force the customer to choose a specific date and time to use the reserved services. The reservation only tells them the period during which they can use the service. That's exactly why this event type isn't suitable for services limited by capacity or a specific time – it doesn't let you set an overall capacity, because it isn't known in advance exactly when the customer will use their reservation.

This event type, or rather these reservations, are suitable anywhere you want to sell your services (typically in the form of tickets) while it doesn't much matter exactly when customers arrive, or what the limiting capacity is. Typical uses therefore include various exhibitions, zoos, historical sites, or various forms of access passes.

Let the reservation system automatically make sure you never have two reservations overlapping at the same time if they use the same resource. Thanks to collision protection, there's no problem creating a complex range of events and services while still ensuring effective management of reservations for the same time slot.

Resources (service, employee, place) in the reenio system serve not only as the informational basis for the range of events, their filtering, and navigation, but also as an important element in automating the whole reservation process. Thanks to collision protection, the system automatically evaluates whether a reservation can be created at a given time, or whether it would cause a collision due to the resources involved already being booked – for example, if a sauna would be booked at the same time by another reservation, but for a different service.

If you want to make reservations really efficiently, and want to offer your customers different options, services, prices, etc., then collision protection is definitely a feature worth understanding and getting right. For example, if you run a tire shop and car wash with 3 bays, thanks to collision protection you can offer different services (events) across the bays, and if a customer books one service in bay 1, no other reservation for the same time can be created for bay 1. And the reservation system takes care of exactly this automatically.

Collision protection is available for almost all event types. It cannot be used to protect against collisions at the level of individual seats in a seat map.

Find out everything you need about customers right at the time of booking – extend the standard form with your own fields and tailor the form to a specific event and type of service.

Custom booking forms let you extend the standard reservation form (name, e-mail, phone) with any additional fields your business needs – from checkboxes, through selecting from options, entering text, all the way to uploading a file (e.g. a photo of the customer or a scanned confirmation). It's also possible to collect specialized data, where the system takes care of validating the correct format.

Individual custom fields can be required, or only shown based on the reserved capacity or a previously selected value. A special group is formed by form fields that affect the reservation price – which makes it easy to handle, for example, a surcharge for renting equipment, a discount for members, or a price adjustment for an above-standard scope of service.

A form can be assigned to a single event, or set globally so it automatically applies to all events on the reservation page. Working with custom forms is therefore very simple while also offering very broad possibilities for use.

Data entered in a custom booking form is saved as part of the specific reservation and can also be included in an export to Excel, and worked with further as needed.

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.

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.
