The short version

  • Only Apache OFBiz has a free tier, so it costs nothing to try first.
  • Each has a real cost: Apache OFBiz oFBiz has disclosed repeated critical vulnerabilities including pre-authentication remote code execution and authentication bypass chains, several exploited in the wild, so an internet-facing instance that is not patched promptly is a genuine breach risk rather than a theoretical one.; 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: Apache OFBiz covers Entity engine, 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.

Apache OFBiz

  • OFBiz has disclosed repeated critical vulnerabilities including pre-authentication remote code execution and authentication bypass chains, several exploited in the wild, so an internet-facing instance that is not patched promptly is a genuine breach risk rather than a theoretical one.
  • There is no vendor, no support contract and no hosted edition, so every deployment depends on either in-house Java skill or an integrator you find and vet yourself.
  • The screens and default workflows look and behave like enterprise software from the 2000s, and user acceptance in a finance or warehouse team is frequently the reason projects stall.
  • It is a framework rather than a configurable product, so meaningful deployments require Java, XML widget and entity engine development, which puts the real cost in developer months rather than licence fees.
  • Localisation for tax, statutory reporting and payroll is largely absent, so any country-specific compliance requirement has to be built, and that build has to be maintained against upstream releases.

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

Apache OFBiz: Is Apache OFBiz safe to run on the public internet?

Only with disciplined patching. It has shipped fixes for pre-authentication remote code execution and authentication bypass flaws, with CVEs continuing into 2026, and some have been exploited in the wild.

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.

Apache OFBiz: What does it cost?

Nothing to licence. It is Apache 2.0. The cost is Java development, hosting and ongoing security maintenance.

Zycus: Which module is strongest?

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

Apache OFBiz: Can I use it as a finished ERP?

Not realistically. It is a framework with reference applications, and most production deployments are custom builds on top of it.

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.

Apache OFBiz: Why choose it over a GPL ERP?

The Apache 2.0 licence is permissive, so an integrator can build and sell a derived commercial product without copyleft obligations.

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.
