The short version

  • Only Zelle has a free tier, so it costs nothing to try first.
  • Each has a real cost: Sila no pricing is published, so you cannot compare Sila against Moov or Dwolla without entering two sales processes, and small programmes frequently find the monthly minimum dominates their cost at low volume.; Zelle both sender and recipient must have US bank accounts, so it does not work for international transfers
  • They diverge on capability: Sila covers ACH origination, Zelle covers Instant money transfers.
  • 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.

Sila

  • No pricing is published, so you cannot compare Sila against Moov or Dwolla without entering two sales processes, and small programmes frequently find the monthly minimum dominates their cost at low volume.
  • Sila is materially smaller and less well capitalised than the banking-as-a-service names it competes with, which matters because your customer funds and your payment rails depend on the vendor still trading in three years.
  • The sponsor bank behind your programme determines what you can offer and how fast you can change it, and bank partnerships in this sector have been reshuffled repeatedly since 2023, so a bank change during your contract is a realistic risk rather than a theoretical one.
  • Coverage is United States only, so any product with cross-border ambitions needs a second payments vendor and a second reconciliation process from the outset.
  • Onboarding involves compliance diligence on your own programme, and teams routinely underestimate this, with weeks lost between signing and first live transaction while policies, flow of funds diagrams and BSA arrangements are reviewed.

Zelle

  • Both sender and recipient must have US bank accounts, so it does not work for international transfers
  • Payments cannot be reversed once the recipient is enrolled, and a payment can only be cancelled while the recipient has not yet enrolled
  • Send limits are set by each participating financial institution rather than published by Zelle
  • Reimbursement is limited to qualifying imposter scams rather than a general purchase protection
  • Business use requires a separate small business account
