The short version

  • Only Mercury has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mercury treasury access requires a $250,000 balance held with Mercury; Socure coverage and accuracy depend on US consumer data density, so international expansion means adding a second, document-based vendor rather than scaling the same contract.
  • They diverge on capability: Mercury covers Business checking, Socure covers ID+ identity verification.
  • 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.

Mercury

  • Treasury access requires a $250,000 balance held with Mercury
  • Non USD international wires carry a 1% conversion fee
  • Choosing OUR wire coding, which covers intermediary bank charges, costs $15 per wire
  • ACH invoicing is $1 per transaction on Mercury Plus and only free on the $299 a month Pro plan
  • Advanced and recurring invoicing require Mercury Plus at $29.90 a month

Socure

  • Coverage and accuracy depend on US consumer data density, so international expansion means adding a second, document-based vendor rather than scaling the same contract.
  • Data-only verification performs worst on thin-file populations, and young, recently arrived or credit-invisible applicants are declined at higher rates, which creates a fair lending exposure a bank must monitor.
  • Pricing is per decision with an annual commitment and is not published, so the cost of a traffic spike or a bot attack on your signup flow lands on your bill.
  • Modules for verification, fraud and compliance are licensed separately, so the shortlist price rarely matches the final contract once screening and document fallback are added.
  • A probabilistic score is harder to defend to an examiner than a documented identification procedure, so US institutions still have to map the score to explicit Customer Identification Programme controls themselves.
