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.

Square

  • Plus plan pricing not specified in documentation
  • Processing fees differ by tier but exact rates not detailed
  • Free plan pricing mentioned but specific features for Plus unclear
  • Text marketing charged at 3¢ per message after first 500 included
