Logistics efficiency with cloud-based analytics for a biotech innovator

Watch how Sii helped Aker Biomarine plan optimal ship routes and crew shifts, boosting logistics efficiency for their krill-based products. We consolidated data from 20 sources in one platform, using Power Apps and Power BI on Google Cloud. This enabled scenario testing, improved supply chain effectiveness, and implemented scalable technologies to reduce costs across all operations.

Advanced cloud management & IT cost optimization

Discover how Sii optimized Mercator's cloud infrastructure using Azure and Intune. Setting up an Azure Landing Zone for efficient cloud migration cut on-prem server costs and automated IT tasks. The solution streamlined remote onboarding and secure device configuration. Equipment was delivered to users' homes, auto-registered with Mercator's network, and all necessary applications were installed and updated via Intune and Autopilot.

Unified cloud solution with D365 for Sales and Field Service

See how we modernized Stalgast's technology stack including MS Dynamics 365 ERP, CRM, and Field Service functions to maintain growth and expand into foreign markets. We implemented Dynamics 365 F&O for finance, purchasing, sales, WMS warehouse, and production, deployed Dynamics 365 Sales as a CRM solution, and utilized Dynamics 365 Field Service for field operations. Additionally, we integrated Dynamics 365 with external solutions like e-commerce and PIM.

All-in-one IT management for PUMA in 4 continents

Learn how Sii implemented Microsoft Intune to digitalize user support and management of endpoints, including back office and POS devices, while maintaining security. We provided L3 support via a shared center for Intune and SCCM, managing both mobile and fixed infrastructure. This approach reduced maintenance costs and adjusted to PUMA's changing needs in 6 time zones across Latin America, India, Asia, Europe, and South Africa.
