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.

Split the work in the administration across your whole team while staying in control of who can see, edit, and configure what – from full administrator access down to simply viewing reservations.

Any number of users, each under their own account, can have access to the reenio reservation system's administration. The system offers several user roles which, combined with specific permissions, clearly define what activities a given user is allowed to carry out.

• Administrator

  Full access to all data and settings.

• Employee

  A flexible role typically for users who manage reservations, events, and communicate with customers, and so on.

• Receptionist

  A role designed for quickly and efficiently working with existing reservations, creating them, and checking them in.

• Read-only

  A supplementary role intended purely for access to information, typically as a safe way to view data.

Thanks to user roles and permissions, working with reservations can be entrusted to other people without them needing access to the reservation page settings or other system parameters – an employee, for example, can process reservations but can't change the system's configuration or access the record of online payments. In specific cases, you can also set a restriction to a specific group of reservations based on a resource (e.g. only a particular branch or service).

Logging in can be secured with two-factor authentication, or password entry can be replaced with modern passkeys – verification by fingerprint, face recognition, or the device's own screen lock.

Collect the documents you need from customers directly during the booking process – consents, confirmations, photos, or other files, which you'll always have on hand for a specific reservation or customer. Similarly, you can also store documents for a specific customer and have a complete profile with their history.

The storage feature lets customers upload, and the system store, files linked to a specific reservation or customer profile. Typical uses include various confirmations, powers of attorney, photos, or copies of documents needed to provide the service – anything that makes communication and the delivery of the service itself easier, because you already have the documents available at the time of booking.

File uploads are added to the booking form using custom forms as a separate form field. A file can also be collected during the customer registration process, through a similar extension of the registration form. Another option is managing files directly in the administration, where you can typically work with them within a specific customer's detail page.

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.

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.

The reenio system is under continuous, ongoing development, which brings new features, integrations with other tools and devices, and improvements to existing features and elements of the administration and the reservation page. Development follows both the needs of users and their businesses, as well as developments in the technology world – new technical solutions or web technologies are gradually incorporated into the system so that every user can work with them effectively.

Development also automatically responds to current formal and legislative requirements, for example in the area of personal data protection (GDPR) or obligations related to reporting illegal content or online withdrawal from a contract. Thanks to this, you can run the reservation system in compliance with current rules without having to track and address every legislative change yourself.

Thanks to the system's concept, which uses cloud technologies for its operation and works as SaaS (Software as a Service), it always holds true that new features or updates are available to all users. The availability of these features and changes is always automatic, and the user doesn't need to carry out any system update or installation.

You can find an overview of news and current changes on an ongoing basis in the documentation or in the system's administration.

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.

The reenio reservation system runs primarily on Microsoft Azure, one of the most widespread and thoroughly vetted cloud solutions in the world. Running in the cloud means you don't have to worry about your own servers, their maintenance, or backing up data – the infrastructure, availability, and security are handled by Microsoft, which invests heavily in the performance, security, and certification of the Azure platform over the long term. Some selected services also run on Amazon Web Services (AWS).

The Microsoft Azure platform was the first cloud solution in the Czech Republic to be vetted and listed in the eGovernment cloud computing catalogue, with the highest achievable security level, BÚ3. Running in such a vetted environment brings greater resilience against attacks or outages, modern data security, and continuous security updates already at the level of the platform itself.

Thanks to cloud operation, the reservation system is accessible from anywhere with an internet connection and can flexibly respond to growing demands – whether in terms of number of customers, reservations, or the volume of data.

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.

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.

Handle payments received in person on the spot too – mark a reservation as paid, generate an accounting document, and print it directly on a POS printer, or accept a card payment right away through a connected payment terminal.

The cash register feature lets you mark a reservation as paid directly in the administration, even when the payment took place outside the online payment gateway, for example in cash at reception. The system can then issue a corresponding accounting document for the payment received this way, respecting the configured document numbering, and so on.

For card payments, the system can also be connected to a payment terminal (SumUp, GP Tom, Comgate), which means a payment request can be sent to the terminal directly with a button in the reservation detail, and after a successful payment the system automatically marks the reservation as paid, creates the payment and document, and sends the customer a confirmation by e-mail, just like with payment via the online gateway.

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.
