iIDMK was founded in 2013, launching an e-service that facilitates the sending and importing of invoices across different applications, including accounting software. Its proprietary system, Maszfaktue.pl, is a desktop application developed in C# using .NET technology and the WPF graphical engine, hosted on the Azure platform. The architecture follows a client-server model based on WCF services. The use of this technology was chosen due to its strong integration with the Windows environment. The customer-facing web component is developed in PHP using the Yii framework, while the website operates on the WordPress platform. Additionally, the system incorporates OCR technology and offers mobile applications for both iOS and Android devices.
