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Localisation depends on community contribution, so tax, payroll and statutory reporting for your country may be absent, out of date or maintained by one person, and you may end up funding it yourself.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.

Katana

  • Limited BOM explosion and lead-time offset planning requiring manual work that should be automated
  • No native invoicing capability, making it standalone without accounting system integration
  • Limited native integrations, with heavy reliance on Zapier for non-core tools
  • Slow performance with large datasets and high SKU counts

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.

Katana: What is Katana's pricing structure?

Katana starts at $99/month for the Essential plan with core MRP features. The Pro plan costs $299/month and adds shop floor control and API access. Add-ons for traceability, manufacturing, and warehouse management cost extra and can reach $747-$1,095 total.

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.

Katana: Does Katana support multi-level bills of materials?

Katana has limited BOM explosion and lead-time offset planning capabilities. Complex multi-level BOMs with sub-assemblies require manual workarounds, which becomes increasingly problematic as SKU count grows.

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.

Katana: Can Katana integrate with my accounting software?

Katana has no native invoicing capability and limited integrations with accounting systems. It is essentially standalone and requires manual data export or Zapier integration for most accounting workflows.

Source
iDempiere: Which database does it need?

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

Katana: Does Katana have an offline mode?

No, Katana is a cloud-only solution requiring internet connectivity. There is no built-in offline mode for production floor access without internet.
