The short version

  • Each has a real cost: Klarna merchant fees for the short-term products run around 5.99% plus a fixed fee in the United States, roughly double a standard card rate, so unless Klarna measurably lifts average order value or conversion it is a straight margin loss.; 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.
  • They diverge on capability: Klarna covers Pay in 4, Sila covers ACH origination.
  • 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.

Klarna

  • Merchant fees for the short-term products run around 5.99% plus a fixed fee in the United States, roughly double a standard card rate, so unless Klarna measurably lifts average order value or conversion it is a straight margin loss.
  • Rates are negotiated and unpublished, which means small merchants pay the standard rate while large ones negotiate down, and you cannot benchmark what you are being charged without going to market.
  • Returns and partial refunds are handled through Klarna's systems rather than your payment processor, so your finance team reconciles a second settlement flow and customer service handles a second dispute process.
  • Buy now pay later is being brought under consumer credit regulation in the UK, the EU and Australia, which is already changing affordability checks and disclosures; the checkout experience that converts today may be legally required to add friction.
  • Klarna owns the post-purchase relationship, sending payment reminders and marketing in its own name, so a shopper who has a poor collections experience associates it with your brand while you have no control over the messaging.

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.

Answered from the vendors’ own pages

Klarna: What does Klarna cost a merchant?

Sila: Does Sila require a sponsor bank?

Yes. Funds sit at a partner bank, and which bank that is affects your product features and your regulatory exposure, so ask before signing.

Klarna: Does the merchant carry the credit risk?

Klarna: Can I use Klarna alongside my existing processor?
