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.; Tyler Enterprise ERP (Munis) implementation is a one to two year project with data conversion and chart of accounts redesign, and the professional services cost regularly exceeds the software cost in the first years.
  • They diverge on capability: Apache OFBiz covers Entity engine, Tyler Enterprise ERP (Munis) covers Fund accounting.
  • 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.

Tyler Enterprise ERP (Munis)

  • Implementation is a one to two year project with data conversion and chart of accounts redesign, and the professional services cost regularly exceeds the software cost in the first years.
  • Nothing is published, and pricing varies substantially between jurisdictions of similar size, so buyers should compare quotes with peer authorities and cooperative contract pricing rather than negotiate blind.
  • Tyler is steering customers from perpetual on-premise licences to cloud subscription, which converts a capital purchase into a recurring operating cost that many jurisdictions have not budgeted for over a ten year horizon.
  • The user experience is generational and module-dependent, with parts of the system still reflecting older design, so occasional users such as departmental approvers need repeated training.
  • Tyler has acquired heavily and its product portfolio overlaps, so a jurisdiction can find itself running two Tyler products that do similar things with an integration between them rather than one coherent system.

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.

Tyler Enterprise ERP (Munis): Is Munis still a product?

Yes, sold as Tyler Enterprise ERP. Users and job adverts still say Munis, and Tyler continues to use the name alongside the new one.

Apache OFBiz: What does it cost?

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

Tyler Enterprise ERP (Munis): What does it cost?

Not published. Licence is quoted by modules, users and population, and implementation is separate. Ask peer jurisdictions of similar size for their contract, which is generally a public record.

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.

Tyler Enterprise ERP (Munis): Can we stay on-premise?

Tyler is directing new business to its cloud offering. Existing on-premise customers are being encouraged to migrate, so model the subscription cost before assuming the old licensing continues indefinitely.

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.

Tyler Enterprise ERP (Munis): Why not use a commercial ERP?

Fund accounting, encumbrances, GASB reporting and state-specific payroll rules are the reason. Corporate ERP requires heavy customisation to satisfy a government audit.
