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 customers a booking for an entire course or cycle of lessons at once – the event is always booked as a single unit, rather than day by day separately.

This event type is fairly specific and lets you define a set of events that are always booked together as a single unit. A typical example is a course taking place every Monday from 9 to 11 for 3 months – a customer doesn't book each Monday separately, but rather books the whole course at once, as an indivisible sequence.

A sequence can also be edited, by using recurrence for the event and then editing individual occurrences, which ensures that all events remain part of the defined sequence. So it's no problem to create a sequence with Monday sessions at 5pm and Wednesday sessions at 7pm.

A sequence is particularly suited to dance courses, swimming courses, educational courses, language classes, kids' clubs, and similar recurring activities.

Offer customers a booking for several consecutive days at once – ideal for rentals and accommodation, which are usually counted in nights or days rather than hours.

This event type lets a customer book one or more consecutive days. In this case, the definition of the events follows on from each other (based on resources), and the system can automatically link such events together. This makes it easy to set, for example, a different price for different days – typically a higher price for weekend accommodation compared to weekdays. Combined with conditional pricing, pricing within this event type can therefore be very flexible.

It's particularly suited to accommodation and space rentals, but you'll also find it useful for all kinds of rental businesses – cars, campervans, e-bikes, or other equipment, where price and availability are calculated at the level of days or nights. By setting a minimum and maximum reservation length, you can easily offer a weekly or weekend rental.

Run your reservation system in compliance with current legislation without having to track every change in this area yourself – we continuously add features that make it easier to meet your obligations. Of course, in this respect the reservation system is just a tool; legislative requirements and processes must always be grounded in the reality of your business, including outside the online world.

For example, as part of GDPR, the reenio system lets you set up automatic deletion of personal data after a chosen period, or keeps track of customer requests to have their personal data deleted. You can also define your own consents that go beyond the defined legitimate interest, and use them as the basis for, for example, sending marketing communications only to customers who have given direct consent for that.

In response to ongoing changes in legislation and amendments to laws, new features have appeared in the reenio system to make it easier to meet the requirements of the so-called "button law", the requirement for easy withdrawal from a contract, or the ability to report illegal content on the reservation page.

Set prices for customers exactly to match your offering – different customer categories, discounts for longer bookings or bookings made well in advance, discount coupons, and any combination of all of these.

The price of a reservation in the reenio system doesn't have to be just a single fixed number – the system provides tools to price your offering intelligently and precisely, in line with how your business works. You can set different pricing categories, for example admission for an individual or a family, which are then automatically factored into the reservation based on the customer's choice.

On top of that, you can tailor the price to the specific circumstances of the reservation – for example, giving a discount to customers who book well in advance, or setting a different rate for a longer stay or rental. Thanks to a custom booking form, you can then easily offer add-on services or a discount for a selected group of customers.

For marketing campaigns and controlled access to selected events, discount coupons are useful, with their own settings for validity and number of uses – whether it's a one-off promotion, a loyalty discount, or a closed group for whom you only open up an event when the corresponding code is used.

The power of this pricing approach lies in the fact that all these tools can be combined and used together as needed. The final price always reflects exactly how you want to offer your services and what the customer themselves chooses.

Run an arbitrarily varied range of services on a single reservation page – one-off events, recurring courses, space rentals, and ticket sales all at the same time? The reenio reservation system can cover even these complex business models.

The reenio reservation system is not limited to just a single type of offering – within one page, you can create any number of resources (places, services, employees) and assign each of them the type of event that best suits that particular offering. This means an hourly court rental via interval events, a monthly yoga course as a full sequence, a one-off seminar as a full single event, and the sale of punch cards or gift coupons, can all run side by side – all on one reservation page and in one administration.

Clarity for such a varied offering is provided by a navigation hub, which can be set up as a multi-step guide, walking the customer through it step by step (e.g. first choosing a service, then an employee or branch).

Last but not least, thanks to collision protection over time, the system also automatically makes sure the same resource (e.g. a specific employee or room) never ends up in two reservations at once, even when it's used across different event and resource types.

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.

Don't lose customers just because an event is already fully booked – let them sign up for a waiting list and automatically notify them as soon as a place opens up for them because an earlier customer cancels their reservation.

The waiting list feature lets customers express interest in a reservation even when an event no longer has free capacity. A reservation doesn't get created for them at that point yet – the system simply records their interest, including their details. As soon as the corresponding capacity becomes available (e.g. another customer cancels their reservation), the system automatically picks a waiting-list candidate from the queue based on order and capacity and creates a standard reservation for them with everything that entails – sending a confirmation, a possible payment request, cancellation rules, and so on. If a candidate on the waiting list doesn't get a spot, the system no longer notifies them any further.

This feature is only available for the Full single event type and must first be enabled and configured for the specific event.

The reenio mobile app (Android and iOS) is mainly used for quick and easy on-the-spot online check-in of individual reservations and tickets. It also includes an overview calendar of reservations and a customer list, so a reservation can be found even without knowing the specific code.

The app is therefore intended for administrators or other users (e.g. temp staff, front-of-house staff, receptionists) who need fast, hands-on access to data and information. This also means that a user doesn't need access to the full system administration to log into the app – a special authorization QR code can be used to log in instead.

A reservation code is primarily scanned as a QR code using the mobile device's camera, but it can also be entered manually or looked up. For larger numbers of visitors, it's a good idea to get a mobile device with a hardware laser code scanner – scanning is significantly faster and more reliable. Combined with automatic check-in mode, where, if everything about the reservation/ticket is in order, the code is automatically marked as checked in a moment after scanning, this becomes a very fast helper.

The app can also check in individual places within a single reservation (e.g. specific seats), and besides reservations it can also handle redeeming coupons or punch cards by scanning their code.

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.

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.

Offer customers a classic bank transfer payment option too, for cases where you don't need instant confirmation – ideal for reservations made well in advance.

Bank transfer payment in the reenio system is especially useful where the deadline for mandatory payment of a reservation is three days or more, or where payment isn't a condition for the reservation to be created at all. The advantage of this approach is that everything happens purely within the reservation system and the bank, without needing an online payment gateway set up. Another advantage is lower costs for processing payments. The downside, on the other hand, is that checking, synchronizing, and the speed of payments is more complex.

The system provides the customer with the payment details (account number, amount, variable symbol – also in the form of a popular payment QR code) needed to send the payment, and based on the variable symbol, the payment can then be traced and matched to a specific reservation or, in the case of gift coupons, a purchase. Matching can be done manually directly in the administration, or automatically – you just need to set up your supported bank to send notifications of incoming payments to a unique e-mail address. As soon as such a notification arrives from the bank, the system matches the payment based on the variable symbol and marks the reservation as paid itself.

Bank transfer is usually also available as one of the methods within the online payment gateway, though in that case enabling it is more of a complication, since it combines completely different payment methods into a single solution. As with other payment methods, the system automatically issues and sends the customer the relevant accounting document the moment the payment is matched.
