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.

Modern Treasury

  • You must already have or be able to obtain your own bank accounts with the right connectivity, so early stage companies without a banking relationship cannot use it and are pushed towards a sponsor bank model instead.
  • Pricing rests on an annual minimum commitment, and companies that miss their volume forecast pay the minimum regardless, which makes the headline per-transaction rate close to irrelevant in year one.
  • Supported bank connectivity is a finite list, so if your bank is not on it you are either waiting for an integration or changing banks, which is a far larger project than adopting the software.
  • It is software over banking, not banking, so it does not solve card issuing, deposit accounts or the licensing questions that a company embedding financial products still has to answer elsewhere.
  • The ledger is genuinely good but adopting it properly means making it the source of truth for balances in your product, which is a significant application change rather than a payments integration and is where implementations run long.

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.

Modern Treasury: Is Modern Treasury a bank or a banking as a service provider?

Neither. You hold your own bank accounts and it is software over them. That avoids sponsor bank concentration risk but means you need the bank relationship yourself.

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.

Modern Treasury: What does it cost?

Not published. A platform access fee plus usage fees across rails, on an annual term with a single minimum commitment. Negotiate the minimum, not the per-transaction rate.

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.

Modern Treasury: Which rails are supported?

ACH, wires, RTP, FedNow, push to card, cheques and stablecoin payments, subject to what your bank supports.

Modern Treasury: Do we still need our own compliance programme?

Yes. KYB, KYC and transaction monitoring are included in the platform, but you are the one holding the accounts and the regulatory obligation sits with you and your bank.
