The short version

  • Only Tryton has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Tryton ordinary series are supported for only one year, so any deployment not pinned to a long term support major version needs a funded upgrade project every twelve months, which is the largest hidden cost of running Tryton.
  • They diverge on capability: Rydoo covers Receipt OCR, Tryton covers Modular installation.
  • 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.

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.

Tryton

  • Ordinary series are supported for only one year, so any deployment not pinned to a long term support major version needs a funded upgrade project every twelve months, which is the largest hidden cost of running Tryton.
  • There is no vendor to buy support from, only a list of independent service providers, so procurement teams that require a single accountable supplier with an SLA have to construct one themselves.
  • The module ecosystem is far smaller than Odoo or ERPNext, so region-specific tax rules, payroll and industry add-ons frequently have to be written rather than installed.
  • Out of the box reporting is thin and there is no built-in business intelligence layer, so most deployments end up exporting to an external tool to get management reporting.
  • Documentation and community discussion are functional but sparse compared with commercial ERPs, which lengthens implementation for teams that have not worked with Tryton before and makes hiring experienced consultants harder.

Answered from the vendors’ own pages

Rydoo: Does Rydoo issue cards?

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

Tryton: What licence is Tryton under?

The platform and official modules are GPL-3.0-or-later. There is no paid enterprise edition.

Rydoo: Is there a minimum?

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

Tryton: How long is a release supported?

Series are released every six months and supported for one year. Major versions get five years of long term support, so pin to an LTS release unless you can fund annual upgrades.

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.

Tryton: Is there a hosted version from the project?

No. The foundation lists independent service providers who offer hosting and support commercially.

Tryton: How does it differ from Odoo?

Tryton has no open core split, so there is no paid edition holding back features, but the module ecosystem and partner network are much smaller.
