The short version

  • Each has a real cost: 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.; Volt account-to-account payments carry no chargeback mechanism, so consumers lose scheme dispute protection and merchants lose a familiar framework for handling claims.
  • They diverge on capability: Modern Treasury covers Multi-rail payment initiation, Volt covers Pay by bank.
  • 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.

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.

Volt

  • Account-to-account payments carry no chargeback mechanism, so consumers lose scheme dispute protection and merchants lose a familiar framework for handling claims.
  • Refunds are outbound payments rather than reversals, which changes treasury handling and means a refund can fail for reasons a card refund never would.
  • Conversion is lower than a stored card because the shopper must complete a bank authentication journey, and drop-off varies significantly by bank.
  • Core pay by bank pricing is per transaction but refunds, payouts, virtual IBANs, Verify and fraud tooling are billed separately, so the real cost is a stack of line items.
  • Bank API availability and quality vary across markets, and an outage at a major bank removes a slice of your checkout with no fallback unless you keep cards live.

Answered from the vendors’ own pages

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.

Volt: Are there chargebacks?

No. Bank transfers are irrevocable, so disputes are handled commercially between merchant and customer, not through a card scheme.

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.

Volt: How do refunds work?

As a separate outbound payment initiated by the merchant, which Volt charges for separately from the inbound transaction.

Modern Treasury: Which rails are supported?

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

Volt: Which markets are covered?

Europe and the UK, plus Brazil and Australia, on a single API integration.

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.
