Where each one falls short

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

Dwolla

  • Nothing is published: there are no per-transaction rates, no platform fee and no minimum on the pricing page, so every buyer negotiates blind and small platforms have no way to sanity check what they are quoted.
  • It is payments only, with no deposit accounts, card issuing or general ledger, so companies embedding financial products need at least one further vendor and the reconciliation between them.
  • Instant payment reach depends on the receiving institution supporting RTP or FedNow, so a meaningful share of payouts still fall back to ACH timing regardless of what the API can do.
  • ACH returns and administrative returns remain your operational problem, and platforms new to bank rails routinely underestimate the customer support load that failed debits generate.
  • Access to instant rails runs through Dwolla banking partner, which reintroduces a bank dependency into a product that otherwise avoids sponsor bank programme risk.

Polar

  • Percentage-based fees higher than some specialized processors for high-volume transactions
  • Merchant of record model may not suit companies preferring direct payment control
  • Free Starter tier limited with 5% fees reducing appeal for production use
  • Setup and integration effort required despite API simplicity
