The short version

  • Only PostgreSQL has a free tier, so it costs nothing to try first.
  • Each has a real cost: PostgreSQL requires manual scaling across multiple machines for very large deployments; Xero the Early plan caps you at 20 invoices and 5 bills per month, and the invoice limit counts both approving and sending
  • They diverge on capability: PostgreSQL covers ACID Compliance, Xero covers Bank reconciliation.

Where each one falls short

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

PostgreSQL

  • Requires manual scaling across multiple machines for very large deployments
  • Performance tuning requires deep knowledge of database internals
  • No built-in graphical admin interface; command-line tools are primary method

Xero

  • The Early plan caps you at 20 invoices and 5 bills per month, and the invoice limit counts both approving and sending
  • Invoices created by connected app partners count against the Early plan invoice limit
  • Multiple currencies, project time and cost tracking, employee expense and mileage claims and industry benchmarking are restricted to the top Established plan at $90 per month
  • Cash flow forecasting is capped at 30 days on Early and 60 days on Growing, with 180 days only on Established
  • Payroll is not included in any plan and costs an extra $36 a month plus $6 per employee or contractor through Gusto
  • Inventory Plus is a paid optional add-on rather than part of any plan
  • The advertised 90% off applies only to the first 6 months, after which the regular $25, $55 or $90 monthly price auto-renews
  • The introductory discount excludes add-ons, usage charges and payment fees
  • Payment fees apply to online invoice payments and to bill payments other than standard domestic ACH, and are billed on top of the subscription
  • Subscriptions are billed monthly with no annual payment option, and after upgrading you must wait one month before downgrading to a cheaper plan
  • Xero states subscription prices are increasing from October 1, 2026
