Software development from Vienna
Kais Solutions builds custom web applications for businesses in Vienna and across Austria and runs its own products – from warehouse management to the digital menu.
Own products
Alongside client projects, Kais Solutions also develops and runs its own applications – for warehouse management, hospitality and family history.
Warehouse & inventory
Warehouse management as a web application
Web-based warehouse management for items, storage locations, stock movements and stocktaking – multi-tenant and for multiple sites.
Hospitality
Digital menu via QR code
Digital menu via QR code for restaurants: multilingual, managed centrally, with order taking for waiters and a kitchen board.
Family & genealogy
Family tree online
Online family tree software: record people, relationships, photos and stories – including for blended families, adoption and large families.
Learning & training
Live quiz for code with verified answers
Live quiz for programming courses: AI writes the questions, and every code question is executed and checked before it goes live.
Contracts
Digital contract management
Create contracts digitally, sign them electronically, store them with versions and keep an eye on deadlines – the first focus is employment contracts.
Administration
Business hub for sole proprietors
Mileage log, customers and projects, fixed costs and tax deadlines in one place – built for Austrian sole proprietors.
