The short version

  • Only Odoo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Odoo the free plan is limited to one app, so any second module moves the whole account to a paid per user plan; SAP S/4HANA implementation and integration costs routinely run to several times the software cost, and the subscription clock typically starts long before go live, so the first contract year buys much less usable production time than the headline suggests.
  • They diverge on capability: Odoo covers Sales management, SAP S/4HANA covers HANA in-memory database.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Odoo

  • The free plan is limited to one app, so any second module moves the whole account to a paid per user plan
  • Standard runs $13.50 to $16.90 per user per month and Custom $20.40 to $25.50, both quoted with a yearly discount applied
  • Implementation services and custom development are not included in any plan
  • Odoo.sh hosting is required for custom modules and is charged separately from the subscription
  • SMS credits and AI scanning are billed on top of the per user price

SAP S/4HANA

  • Implementation and integration costs routinely run to several times the software cost, and the subscription clock typically starts long before go live, so the first contract year buys much less usable production time than the headline suggests.
  • Custom ABAP from an ECC installation must be assessed against the simplification list and either retired or rebuilt, and this remediation is normally the largest and most underestimated line in a brownfield conversion.
  • The public cloud edition constrains modification by design, so organisations that depend on non-standard processes are pushed either to change the process or to pay for the private edition, and that decision is often made after the contract is signed.
  • SAP intends extensions to live on the separately licensed Business Technology Platform, so the extensibility model that makes upgrades safe also adds a second subscription and a second set of skills to the total cost.
  • Exit is effectively impossible at reasonable cost, because the data model, the accumulated configuration and the trained staff around a large installation represent a switching cost that outweighs any competing vendor's discount, so the decision binds for a decade or more.

Answered from the vendors’ own pages

Odoo: How much does Odoo cost per user?

Odoo pricing ranges from $0/month for one free app with unlimited users, to $13.50-$16.90/month per user for Standard, and $20.40-$25.50/month per user for Custom, depending on billing frequency (yearly vs monthly).

Source
SAP S/4HANA: What is the actual deadline for leaving ECC?

SAP has set mainstream maintenance for the older Business Suite to end in 2027, with paid extended maintenance available for a further period to 2030. Confirm the current dates and terms with SAP directly, because the commercial detail has been adjusted more than once and it determines your negotiating window.

Odoo: Is there a free Odoo plan?

Yes, Odoo offers a free plan that includes unlimited users for one app with hosting and support included on Odoo Online.

Source
SAP S/4HANA: Greenfield or brownfield?

Brownfield carries your existing configuration and custom code forward, which is faster to start and slower to finish because everything must be remediated. Greenfield rebuilds on standard processes, which costs more in change management and leaves a cleaner system. The right answer depends mostly on how much of your existing configuration you would defend to a board.

Odoo: How does Odoo define a paying user?

A paying user is typically an employee who has access to the Odoo backend to create, view, or edit documents. Customers and suppliers accessing portals are free users and do not count toward the seat limit.

Source
SAP S/4HANA: Is the public cloud edition cheaper?

To run, generally yes. Whether it is cheaper overall depends on whether your processes fit within its extensibility limits. If they do not, the savings evaporate into workarounds or into a move to the private edition.

Odoo: What is included in Odoo's Standard plan?

The Standard plan at $13.50-$16.90/user/month includes all Odoo apps, hosting, unlimited support and maintenance, daily backups, 24/7 monitoring and security, and free eLearning platform access.

Source
SAP S/4HANA: How should I approach pricing negotiation?

Treat licence, infrastructure, BTP, the integrator and the internal backfill as one number and negotiate against it. Also settle indirect and digital access terms explicitly in writing, since usage from connected systems has been a recurring source of unbudgeted cost.
