The short version

  • Each has a real cost: Highnote card issuing requires a sponsor bank, and that bank sets programme approval, compliance obligations and often minimum volumes, so a small programme can be rejected regardless of technical fit.; 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: Highnote covers Card issuing, 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.

Highnote

  • Card issuing requires a sponsor bank, and that bank sets programme approval, compliance obligations and often minimum volumes, so a small programme can be rejected regardless of technical fit.
  • Pricing is entirely quoted, including platform fees, per active card charges and monthly minimums that do not appear on the website, so the true cost per card is only visible late in a sales process.
  • Interchange sharing is the real revenue model for most customers, and the split is negotiated, capped for regulated debit under the Durbin amendment and sensitive to your spend mix, so revenue projections built on headline interchange rates overstate income.
  • Running issuing and acquiring with one provider concentrates risk: an outage or a compliance action affects both money in and money out at the same time.
  • Highnote is a younger company than the established issuer processors, so long term programme continuity, network certifications in new geographies and international coverage are thinner than the incumbent alternatives.

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

Highnote: Do I need a sponsor bank?

Yes for card issuing in the United States. Highnote is a processor and programme platform, not a bank, and the sponsor bank sets approval and compliance terms.

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.

Highnote: How do customers make money on a card programme?

Mostly interchange sharing. Negotiate the split explicitly and model it against your actual spend mix, since regulated debit interchange is capped.

Sila: Is Sila still operating?

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

Highnote: Can Highnote handle both accepting and issuing payments?

Yes since its 2025 acquiring launch, on the same ledger, which is its main structural differentiator.

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.
