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Localisation depends on community contribution, so tax, payroll and statutory reporting for your country may be absent, out of date or maintained by one person, and you may end up funding it yourself.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.
Twenty
- Requires technical expertise to customize and maintain compared to no-code CRM platforms
- Self-hosting increases operational overhead and infrastructure costs
- Limited ecosystem of pre-built integrations compared to Salesforce
- Smaller community and third-party extension library than established CRMs
- Enterprise plan requires custom negotiation with no transparent pricing
