Background
GEALAN Serbia, part of the internationally recognised GEALAN Group in the fenestration industry, needed an ERP platform to support increasing operational complexity while aligning with group-level expectations. The objective was a unified, efficient environment across sales, finance, procurement, inventory and operations — built on a scalable foundation that could scale with the business. SAP Business One was selected as the core ERP platform, complemented by the Boyum B1UP add-on for targeted customisation.

Key Challenges & How We Addressed Them
Challenge 01 Localization Gap
| Challenge | No dedicated Serbia localization existed in SAP Business One at the time of implementation, creating a compliance and operational fit risk. |
| Approach | Adopted the Hungary localization as the closest operational fit. Performed detailed mapping of Serbian tax and statutory requirements, adjusted processes where needed, and rigorously validated financial transactions and reporting structures. |
| Outcome | A compliant, stable ERP environment delivered despite the localization limitation. |
Challenge 02 Complex Discount Structures
| Challenge | Pricing involved multiple layered discounts, customer-specific pricing, promotional discounts, and combinations of document-level and item-level discounts. |
| Approach | Worked directly with business stakeholders to capture every pricing scenario, configured tailored discount workflows in SAP B1, and validated calculations end-to-end across quotations, orders, and invoices. |
| Outcome | Accurate, automated commercial calculations with significantly reduced manual intervention and pricing inconsistencies. |
Challenge 03 Regulatory & Statutory Alignment
| Challenge | Aligning local statutory requirements with a non-Serbian localization required deep process mapping and validation. |
| Approach | Focused on tax handling, financial reporting structures, compliance-oriented documentation, and consistency of processes across departments. |
| Outcome | A workable, defensible framework supporting both operational efficiency and local compliance expectations. |
Challenge 04 User Adoption & Go-Live Transition
| Challenge | ERP transformations live or die on change management — adoption was a critical success factor. |
| Approach | Cross-functional collaboration sessions, structured user training, process walkthroughs, business alignment workshops, and continuous hands-on support during cutover. |
| Outcome | A stabilized go-live with reduced disruption and confident user adoption. |
