The short version

  • Only ADempiere has a free tier, so it costs nothing to try first.
  • Each has a real cost: ADempiere there is no company behind it, so there is no support contract to buy, no SLA, no escalation path and no roadmap commitment; if your implementation partner leaves the market you own the problem entirely.; Rydoo a five-user minimum means very small teams pay for seats they do not have, which removes Rydoo from consideration for firms of two or three.
  • They diverge on capability: ADempiere covers Application dictionary, Rydoo covers Receipt OCR.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

ADempiere

  • There is no company behind it, so there is no support contract to buy, no SLA, no escalation path and no roadmap commitment; if your implementation partner leaves the market you own the problem entirely.
  • The official website adempiere.net does not resolve, which strands most of the historic documentation and tutorials that search engines still point at and makes onboarding a new developer considerably harder.
  • The last conventional stable release, 3.9.4, is from January 2023, so despite ongoing GitHub activity a buyer evaluating on release cadence sees a project moving slowly.
  • iDempiere, a later fork of the same codebase, absorbed much of the developer community, so ADempiere competes for contributors with its own descendant and is the smaller of the two ecosystems.
  • The interface and the Java Swing heritage feel dated, and staff coming from a modern cloud ERP will need training and will complain; expect resistance from finance and warehouse users during rollout.

Rydoo

  • A five-user minimum means very small teams pay for seats they do not have, which removes Rydoo from consideration for firms of two or three.
  • Pricing is per user rather than per active user, so organisations where most staff claim expenses twice a year still pay a full seat every month for them.
  • There is no card issuing, so real-time spend control and pre-authorisation are outside the product and remain with your bank.
  • Per diem and multi-entity handling sit on the higher tier, so the countries that most need Rydoo generally cannot buy the cheap plan.
  • Receipt extraction quality varies by language and receipt format, and finance teams still review a meaningful share of claims by hand.

Answered from the vendors’ own pages

ADempiere: Should I choose ADempiere or iDempiere?

Look at iDempiere first. It is a later fork of the same codebase with a more active community and a modular OSGi architecture. Choose ADempiere if a specific partner or localisation you need only exists there.

Rydoo: Does Rydoo issue cards?

No. It is expense software only; you keep your existing corporate card or bank programme.

ADempiere: Is ADempiere free?

The software is GPL licensed with no licence fee. The cost is implementation, customisation and permanent in-house maintenance, which for a real deployment is substantial.

Rydoo: Is there a minimum?

Yes, pricing carries a five-user minimum, so the smallest bill is five seats regardless of headcount.

ADempiere: Is the project still alive?

Development continues on GitHub with commits into 2026, but the official website is down and the last stable release is from January 2023. Treat it as maintained rather than actively advancing.

Rydoo: Do I need the Pro plan?

If you operate per diems, multiple legal entities or multi-currency claims, yes. Essentials is for single-entity receipt and approval workflows.

ADempiere: What is the application dictionary?

It is the metadata layer inherited from Compiere that stores the definition of every window, field and validation rule as data, so you can change the application without touching source code.
