The short version

  • Only Afterpay has a free tier, so it costs nothing to try first.
  • Each has a real cost: Afterpay a missed instalment triggers a late fee, and while total late fees on a purchase are capped, repeated missed payments across multiple purchases can add up to a meaningful cost that the interest-free marketing does not foreground.; 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: Afterpay covers Four-instalment split, Sila covers ACH origination.
  • 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.

Afterpay

  • A missed instalment triggers a late fee, and while total late fees on a purchase are capped, repeated missed payments across multiple purchases can add up to a meaningful cost that the interest-free marketing does not foreground.
  • Afterpay has updated its reporting policies so that late payment history can be shared with credit bureaus in some markets including the US, meaning a product marketed as simple instalments can now affect a credit score.
  • Merchants pay a transaction fee commonly in the 4 to 6 percent range plus a fixed fee, well above standard card processing, a cost that is typically absorbed into retail pricing rather than disclosed to the shopper choosing to use Afterpay.
  • Spending limits and approval are based on repayment history within the app rather than a full credit check, which can make it easier to accumulate multiple concurrent instalment obligations across different purchases than a shopper realises.
  • It is only usable at participating retailers or via the Afterpay Card, so coverage is narrower than a general-purpose credit or debit card despite behaving like one at checkout.

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

Afterpay: Does Afterpay charge interest?

Not on the standard four-instalment Pay in 4 plan if every payment is made on time; longer instalment plans in some markets can carry interest, and missed payments incur late fees regardless.

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.

Afterpay: Can Afterpay affect my credit score?

Afterpay has updated its policies so that late payment history can be reported to credit bureaus in some markets including the US, which can affect a credit score even though the core product is marketed as interest-free.

Sila: Is Sila still operating?

Yes. It continues to trade and announced an API integration with GBank in 2025 covering ACH, RTP and FedNow.

Afterpay: Who actually pays for Afterpay to be free for shoppers?

Merchants pay a per-transaction fee, commonly 4 to 6 percent plus a fixed fee, which is generally built into retail pricing rather than shown to the shopper.

Sila: What does it cost?

Sila does not publish rates. Expect per-transaction pricing plus a monthly minimum, quoted after a compliance conversation.

Sila: Can I use it outside the United States?

No. Sila covers US rails only.
