About
Ugur Hasdemir: Independent S/4HANA Finance Architect
I make sure the financial truth matches the operational reality. For 15+ years I have designed and validated SAP S/4HANA Finance for global manufacturers, utilities, and logistics businesses, and I do it independently of any System Integrator.
Independent S/4HANA Finance Architect · Utrecht, Netherlands · SAP Press author
What I do
I am a Finance-first design validator. While System Integrators build to the spec they are given, I check whether the spec is right: enterprise structure, ledger and group valuation, margin analysis, product costing, intercompany, allocations, and the close. When the design is sound, programs avoid the expensive rework that surfaces after go-live.
Track record
I have led Finance design on enterprise S/4HANA programs, including Content Lead for the Accounting and Controlling streams of a major European utility's next-generation ERP program, with key design decisions spanning ledger models, segment and profit-center design, margin analysis, overhead cost accounting, value flows and settlements, and intercompany billing. My work has supported finance transformations at organizations including Unilever, Air France-KLM, Cargill, and LeasePlan.
Credibility
I am an SAP Press and Rheinwerk author, and I write regularly at s4hanablog.com on the design decisions that make or break S/4HANA Finance.
How I work
Independent, vendor-neutral, and direct. I tell you what I see, not what is comfortable. I am based in Utrecht and work with programs across the Netherlands and DACH.
Depth of coverage
Where my work goes deep.
Target Operating Model Design
The finance operating model behind the system: enterprise structure, ledgers, and the reporting dimensions that decide how the business steers and closes.
Finance Integration into Logistics & Manufacturing
The value flows where logistics and production become financial postings, so inventory, costing, and the P&L agree.
Financial Accounting, AP/AR & Fixed Assets
General ledger, payables, receivables, and asset accounting designed to close cleanly and satisfy both group and local reporting.
Investment Management
Capital and project spend from budget through settlement, with the controls and capitalization that keep CAPEX auditable.
Product Costing & Overhead Cost Accounting
Costing runs, overhead allocations, and variance analysis that tie standard and actual cost back to a margin you can defend.
