SAP S/4HANA and Odoo: the core stays, the units move faster

For groups on SAP Cloud ERP Private (S/4HANA Cloud, private edition) or S/4HANA on their own servers.

Too deep?

The short answer

• SAP S/4HANA, private edition and on-premise is a good fit for large groups that need the deepest processes and control over their own landscape.
• Odoo is a good fit for subsidiaries, acquisitions, new countries and service units around the group core.
• TRC ERP sets Odoo up for your business and connects what you keep.

What SAP S/4HANA, private edition and on-premise does well

• S/4HANA, in the private edition or on your own servers, runs the most complex group operations, with deep finance, supply chain and industry processes.
• It suits groups that want control over their own upgrades and extensions.

Where Odoo fits

• Keep S/4HANA as the group core. Odoo runs subsidiaries, acquisitions, new countries and retail or service units, posting to the group.
• Large S/4HANA programs often carry existing processes forward. A unit on Odoo can work in new ways now, joined to the core, without waiting for the next rollout wave.

The deciding factor: Whether the unit needs the group's full template, or its own operations joined to the group ledger.

Two-tier ERP. Your group core stays the system of record. Odoo runs this unit and feeds the core. How two-tier works

Timing for larger organizations

For larger organizations, the requirements stage is shaped to you. If your processes are documented and your requirements are clear, 60 days can be enough. Most larger organizations need a little longer. We agree the timing and terms with you, and often it is still at our risk.

• The unit needs the group's full template and only reports into it.

Questions buyers ask

Whether the unit needs the group's full template, or its own operations joined to the group ledger.

No. One company, site or process first, with what you keep connected.

Journeys to explore

• Open a country operation in months, feeding the group core A telecoms group is launching in a new country: stores selling devices and contracts, field engineers installing service, a help desk taking customer tickets and a local finance team. A rollout of the group core to the new country would not be ready for the launch date.
• A group upgraded its core. Now modernize the divisions. A diversified group has just finished a long upgrade of its core ERP. Each division still runs its own separate system, and the team is tired of big programs.
• Move one existing division off its own system, with the group core unchanged A group's hospitality division has run its own separate system for years, beside the group finance system. Figures are re-keyed into group reporting every month, and the division's managers can't see margin by outlet until long after the month ends.
• Large enterprise Keep your group core, connect around it, or replace it in phases.
