Transition from legacy on-premise ERP (Microsoft Dynamics GP) to S/4HANA Public Cloud for Winncom

Winncom, a global distributor and provider of telecom solutions, was using a legacy on-premise ERP system that lacked scalability, had limited capabilities, failed to provide visibility across global operations, and featured inefficient and sometimes manual operations. Additionally, the platform was nearing the end of its life.  Winncom was seeking a modern and efficient cloud solution to replace their existing system, support their growth, and streamline business operations in accordance with best practices. They chose to migrate to S/4HANA Public Cloud and subsequently implement SAP Sales Cloud, aiming to achieve an integrated, cloud-first, AI-driven platform that connects and unifies sales and operational processes. 

Winncom turned to ACBaltica to guide their leap into the cloud. The result? Faster operations, better control, and record-breaking sales in the first month after go-live.

Customer

Winncom Technologies is a global distributor and provider of comprehensive networking solutions – both wireless and wired. The company operates in 17 locations worldwide, including:

• 7 offices in North and South America

• 5 in Europe

• 4 in Asia

• 1 in Africa 

 Challenge

Winncom was relying on a legacy on-premise Microsoft Dynamics GP ERP system that had become a barrier to growth. The platform lacked scalability and couldn’t support key functions – especially in logistics and global visibility. Additionally, it was nearing end-of-life, meaning end of support, no critical security updates. 

Some critical issues included:

• Manual and fragmented processes (many handled in Excel)

• No proper workflow for essential processes (e.g., payments or fixed asset tracking)

• Missing sales orders due to email-only communication and non-transparent sales order flow

• Inability to properly track debts, assets, and approvals

• No real-time data to support decision-making

The company was ready to standardize operations, digitize core processes, and enable real-time insights to support business growth and improve customer experience, eventually increasing revenue opportunities. 

Solution

Why SAP

Winncom selected SAP S/4HANA Public Cloud Edition, and later added SAP Sales Cloud, to build a modern, AI-ready, cloud-first ERP ecosystem. Key reasons for choosing SAP included:

• Real-time visibility across all business units
• Streamlined workflows with automation
• Cloud-first approach aligned with Winncom digital transformation strategy
• Standardized best practices – no need for heavy customizations
• LowerTCO

Why Public Cloud

Winncom wanted out-of-the-box best practices, not a heavily customized solution. That made the Public Cloud Edition of S/4HANA the ideal fit: scalable, efficient, and fast to implement.

Implementation process

The project started with the goal to implement/automate 45 processes, and eventually the list grew to 73 processes, covering automation for lines of business listed below (LoB):

• Finance
• Sales
• Sourcing and Procurement

Previously, all those processes were carried out in a custom way – but with the transition to SAP S/4HANA, they were implemented according to SAP best practices. 
Since Winncom doesn’t have an internal IT team, business users led the process. Due to that, some gaps were discovered late in the project. However, thanks to ACBaltica’s on-site support, the go-live in North and South America proceeded smoothly. Due to careful preparation, the ACBaltica team successfully avoided downtime and went live without pausing business processes. A global rollout is planned next.

Results and benefits

Due to the transition from the legacy on-premise ERP and implementation of SAP S/4HANA Public Cloud Edition, Winncomm gained the following benefits:

• Record sales in March 2025 – the first month after go-live
• Significantly reduced month-end closing time
• Streamlined operations and improved internal efficiency
• Real-time visibility into global activities and deadlines
• Sales and operational teams aligned through one platform

With SAP S/4HANA Public Cloud, Winncom moved from outdated, manual systems to a connected, cloud-based, data-driven operation – and the results speak for themselves.
