Planning, reporting and consolidating in the trading network
How do you manage a retail group with a turnover of around two billion euros? The trading group expert SE, based in Langenhagen, relies on an intelligent solution for planning, reporting and consolidation.
With consumer electronics, information technology, telecommunications, entertainment and electrical household appliances, expert achieves annual sales of over 2.2 billion euros (2020/21). Around ten years ago, growing requirements and increasing complexity prompted the expert SE headquarters to introduce the Corporate Planning controlling software.
From KER to an integrated solution
At expert, Corporate Planner was initially used for the short-term income statement (KER). Strategic and operational controlling, integrated financial planning and group consolidation are now intertwined. Flexible analyses, agile and resilient planning as well as audit-proof financial statements for management and legal consolidation contribute to the success of the trading group.
Time savings through automation
“Bundling current data, distribution and processing, individual analyzes and company-wide consolidation – all of this has to be a lean process for us,” says Hakan Kelloglu, authorized representative and head of accounting/controlling at expert SE. “With Corporate Planner we have reduced the effort for complex processes and simplified processes.”
expert achieves significant time savings through automatic imports of data from different source systems and the automated preparation of the data for further processing. The central solution also ensures uniform reporting at expert headquarters and at subsidiaries. Changes to account structures or reports can be made quickly and securely for all subsidiaries with their current 62 locations.
Transparency at any aggregation level
Information from sales, marketing and other departments is incorporated into group-wide planning. Together with the KER data from the individual companies, they serve as the basis for the year-end forecast and the five-year planning for management.
The solution with the corporate planning software automatically derives the balance sheet and financial planning for the entire retail group from the profit and loss planning (P&L). Intelligent business calculation logic automatically generates group planning from the individual plans with a high level of transparency at any aggregation level. During the Corona pandemic, expert was able to quickly create lockdown scenarios and simulations and use them as a basis for decision-making.
Reduced effort, faster action
With the support of the consulting firm Trusted Decisions, expert optimally implemented the corporate planning software solutions for operational controlling, financial planning and consolidation and achieved massive time savings in existing tasks as well as in implementing new requirements. This means that tasks such as creating the KER can now be carried out comfortably. Planning, analysis and reporting have been greatly accelerated. The cost of consolidation was massively reduced.
