Where each one falls short

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

iDempiere

  • There is no vendor, so there is no support contract, no service level agreement and nobody to escalate to; you either build the skills internally or you depend entirely on a local partner whose quality you must judge yourself.
  • It demands real Java, OSGi and PostgreSQL administration, so the running cost is a systems engineer rather than a subscription, and that engineer is harder to hire than a PHP developer.
  • The ZK-based interface is dense and dated, with a data-entry feel inherited from Compiere that staff used to modern software find hostile, which drives up training cost.
  • Localisation depends on community contribution, so tax, payroll and statutory reporting for your country may be absent, out of date or maintained by one person, and you may end up funding it yourself.
  • The documentation is a community wiki with gaps and stale pages, and much of the practical knowledge sits in forum threads and partner heads rather than in anything you can hand to a new administrator.

Odoo Inventory

  • The One App Free plan covers a single app, so using Inventory alongside another Odoo app moves the account onto a paid plan
  • The Standard plan at $16.90 per user per month is restricted to Odoo Online hosting
  • Odoo.sh and on premise hosting require the Custom plan at $25.50 per user per month
  • Odoo Studio, multi company management and external API access require the Custom plan
  • Billing is per user, defined as any employee with backend access to create, view or edit documents
  • The advertised discounted rates apply for the first 12 months, after which the list rates of $21.10 and $31.90 per user per month apply

Answered from the vendors’ own pages

iDempiere: Is iDempiere the same as ADempiere or Compiere?

It shares the lineage. iDempiere forked from ADempiere in 2011 to rebuild the platform on OSGi, and it is the branch that remains actively developed.

Odoo Inventory: How much does the Odoo Inventory app cost?

The Odoo Inventory app is free, forever, with unlimited users at no cost. Additional costs only apply if you install other applications in the Odoo suite.

Source
iDempiere: Is there a paid or enterprise edition?

No. There is no commercial owner and no feature gating. Money is spent on implementation partners and hosting, not on licences.

Odoo Inventory: Do I need to pay to use Odoo Inventory?

No, Odoo Inventory is completely free with no credit card required to start. The free trial and app remain free indefinitely.

Source
iDempiere: What does it actually cost to run?

Nothing in licence fees, and a great deal in skills: expect a partner implementation and ongoing Java and PostgreSQL administration, which for a mid-sized company is comparable to a commercial subscription.

iDempiere: Which database does it need?

PostgreSQL or Oracle. PostgreSQL is the mainstream community choice and the one most partners deploy.
