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; Zycus implementations run long and are consultant-led, so the gap between the sales demonstration and a configured live system is measured in quarters, during which the licence is already being paid.
  • They diverge on capability: Odoo covers Sales management, Zycus covers Spend analysis.
  • Prices and features above were last checked on 31 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

Zycus

  • Implementations run long and are consultant-led, so the gap between the sales demonstration and a configured live system is measured in quarters, during which the licence is already being paid.
  • The AI capability is marketed well ahead of what is typically enabled in a customer instance, and buyers should insist on seeing agentic features running on their own data before valuing them in a business case.
  • A large share of engineering and support capacity sits in India, so North American and European customers need coverage windows and escalation paths written into the contract rather than assumed.
  • The user interface across modules is inconsistent, reflecting different development eras, which raises training cost and reduces adoption among occasional requisitioners.
  • Pricing is entirely quoted and structured around spend under management, so a business whose spend grows faces increases unrelated to how much it uses the software.

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
Zycus: Is it cheaper than Coupa or Ariba?

Usually on licence, and that price gap is the most common reason organisations shortlist it. Compare total cost including implementation, where the gap narrows.

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
Zycus: Which module is strongest?

Spend analysis. Classifying dirty purchase data across multiple ERPs is where Zycus consistently performs well against alternatives.

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
Zycus: How long is an implementation?

Plan for several quarters for a multi-module deployment. Phase it so one module delivers value before the rest go live.

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
Zycus: What about support coverage?

Much of the delivery and support organisation is in India. Get the coverage hours, response times and escalation route into the contract explicitly.
