The short version

  • Each has a real cost: Lago free tier limited to 10,000 entities per month with 5M event cap; 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: Lago covers Real-time usage metering, Tryton covers Modular installation.
  • 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.

Lago

  • Free tier limited to 10,000 entities per month with 5M event cap
  • No specific pricing published for Pro annual plan or Scale plan
  • Self-hosted and on-premise deployments require engineering resources
  • Community support only on free tier
  • Scale plan requires annual contracts and sales engagement

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.
