Integration and business environment development

Direct and efficient solutions to do more

Development and integration of extensive, multiplatform business software environments are one of our core areas of expertise. We take the position, that in most cases when you need new functions and add-ons to the legacy applications, there’s no need to exchange them for new complex solutions. A much simpler and affordable solution is to develop new microservices or even larger applications and smoothly integrate them with the existing pieces of your software. A solution like this usually requires far less time and money and can be implemented in a simple way, without the need to disrupt your core day-to-day business processes.

We willingly assist in every stage of your company’s software development, no matter if it has existed for decades or only been built a few years ago. We assess your specific needs for new functions, add-ons, and extensions. We then analyze the existing components of your system such as applications, databases, and both frontend and backoffice user interfaces.

What’s in it for you?

A profound experience

Since 2001 3e Software House has been involved in dozens of business software development and integration projects. We have integrated complicated logistical processes for companies such as DHL Parcel, where we power a multifunctional customer service portal with an extensive parcel collection point network, a large number of APIs for corporate clients, and companies' internal applications as well.

Our experience includes multiple web and mobile GUI integrations. 

We provide integrations with payment and fiscalization services,  geographic information systems, call center applications and much more. Our main integration projects are those including Oracle Micros applications. It’s a popular HORECA enterprise management system, that we are able to enhance in multiple ways including external the menu presentation layer, creation, and integration of web and mobile food ordering interfaces, geolocalisation services, loyalty platforms, and much more. We also possess a deep knowledge of Micros internal menu models and internal scripts.

Oracle Micros platform development and integration

Micros (acquired by Oracle in 2015) workstations have hummed under the front desks of restaurants and hotels for decades. But progressing digital transformation of food and hospitality industries requires integration with other systems and the development of new functions. That’s where we come in.

We have already made such extensions:

  • web and mobile ordering interfaces
  • in-store ordering kiosks
  • online and in-store menu presentation
  • loyalty schemes
  • food delivery management and monitoring
  • online payments and fiscalization
  • many more

We can integrate it


We possess a thorough knowledge of the application, its interfaces, and APIs. We know nearly everything RES POS API - this SOAP-powered API is the main gate to reach from outside to the restaurant server. For example, it is a for web/mobile ordering applications to send order details straight to the restaurant’s system.

PMS/SIM socket

This API is used in each POS (point of sales) post. Posts using POS3700 or similar software can reach through it to communicate with various external applications, ie. with the loyalty system, to check for customer’s grade and calculate his personal discount, or with a delivery system to direct a driver to

Micros Enterprise Manager

The third way to communicate with Micros ecosystem provides access to its main headquarters. Enterprise Manager stores master data about the whole chain’s menus and price lists and can be used to prepare web and mobile menus, pre-calculate orders values, and much more.

We can program it

Integration is important, but it’s useless unless you understand the internal functioning of an app. We are the ones, who know the internal nitty-gritty of Micros as well as its APIs. As example:

We know Micros modules

We understand how Micros defines products. We figured out how they work from simple products such as a Coke bottle, through to various combo meals, their composition, and pricing, to the most complicated one of all - the pizza. We can enhance Micros models, ie adding a picture and producing model-based interfaces. This knowledge enables us to insert and send orders from external applications to Micros through RES POS API.

We can program POS machines

We know ISL scripts - a scripted language that runs on POS3700. Knowing this script we can simply program POS machines to enhance their built-in functions, adding new buttons and functions available for POS operators - ie. related to external software.
