90% cost reduction
Industry transformation case study
The client & the challenge
Start with the business.
MAR Group’s business brings together manufacturing and trading, including its SONAI home-appliance brand. Its ERP requirements span injection moulding, multi-stage assembly, wholesale activity and a related retail business—an operating model that requires both company-level discipline and group visibility.
Replacing an enterprise ERP must preserve the controls the business depends on. MAR Group’s documented requirements address multi-level BOMs, manufacturing costs, stock availability, intercompany transactions and consolidated reporting. The commercial objective is a materially lower-cost platform with capabilities aligned to those operating needs.

The TDS approach
TDS’s Odoo scope replaces SAP S/4HANA Cloud with a connected model for manufacturing and distribution. Production demand feeds purchasing requirements and approvals; intercompany document flows connect entities while preserving separate ledgers. The design also includes strict negative-stock prevention, serial tracking for finished electrical appliances, manufacturing cost variance treatment and channel-level financial reporting.
Business value first
What the design makes possible
Reset the cost proposition
TDS reports a 90% cost reduction for MAR Group’s SAP S/4HANA-to-Odoo transition. The figure is a client-specific comparison, not a general promise for every SAP migration.
Protect operational discipline
Negative-stock prevention and purchase approval requirements are explicit parts of the design. Lower platform cost does not remove the need for strong transaction controls.
Connect product and group economics
Manufacturing costing, variance treatment and intercompany flows provide a foundation for examining performance across products, channels and legal entities.
The 90% cost reduction is confirmed by TDS management. The reviewed evidence does not define its calculation period or establish an audited whole-life TCO result. The operational capabilities shown are documented project scope; completed go-live, feature-for-feature equivalence and realized operational gains are not asserted.
What makes this case special
Industry knowledge, expressed in the workflow.
This case brings together an enterprise ERP transition and a detailed manufacturing operating model. TDS’s value is in matching the replacement platform to real production, inventory and finance requirements. Any AI capabilities require their own verified scope and are not assumed to be delivered by this migration.
