Case Study: Denmark-based corporate expense-management provider consolidates 4 apps into 2 native solutions and scales to 210,000 daily users with Altoros

Unifying Corporate Business Trip Management for 210,000+ Users

A Denmark-based provider of corporate expense-management software (founded in 1997 and operating in 46 countries) turned to Altoros after customer complaints that four Xamarin-based apps fragmented the business-trip workflow and limited features like receipt recognition, GPS, and in‑app billing. The provider needed native, scalable, secure mobile apps to consolidate receipt submission, mileage, time tracking, and approvals into a single, user-friendly solution.

Altoros delivered modular native apps for iOS and Android (eight modules each), added security measures (AppAuth, in‑app purchase validation), used Google ML Kit and OpenCV for receipt detection and 98% text-recognition accuracy, introduced RPA for automated expense approvals, and migrated XML to JSON to cut server response time by 10x. As a result, the company’s daily active users rose from 117,000 to 210,000 across 1,000 enterprises, App Store satisfaction jumped from 2 to 4+, and the apps became more secure, scalable, and easier to maintain.
