The short version

  • Each has a real cost: Skyflow reported contracts near 195,000 US dollars a year with a platform fee before usage put this out of reach of early stage companies, which are precisely the ones whose architecture is still cheap to change.; 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: Skyflow covers Tokenised storage, 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.

Skyflow

  • Reported contracts near 195,000 US dollars a year with a platform fee before usage put this out of reach of early stage companies, which are precisely the ones whose architecture is still cheap to change.
  • Every read of a protected field becomes a network call to a third party, so latency and an external availability dependency enter paths that were previously local database reads, and outage planning has to account for a vendor you do not control.
  • Analytics and joins on vaulted data are constrained; work that was a simple SQL join now happens through secure functions or on tokens, and data teams routinely discover this after the engineering team has committed.
  • Unwinding the vault later is a rewrite rather than a migration because tokens are threaded through every service, so the switching cost climbs steadily and the negotiating position at renewal weakens with each release.
  • Scope reduction is an architectural claim your own assessor must accept, so the audit saving is real only if the implementation genuinely keeps sensitive values off your systems, and partial implementations that leave a cache or a log line in place deliver the cost without the benefit.

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

Skyflow: Does Skyflow really take my systems out of PCI scope?

It can, if card data never touches your infrastructure and the detokenisation happens at the boundary. Your QSA has to agree the design, so validate the architecture with your assessor before signing.

Volt: Are there chargebacks?

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

Skyflow: What does it cost?

Nothing is published. Reported annual contracts sit around 195,000 US dollars, built from a platform fee plus usage by data subject count and additional charges per data residency region.

Volt: How do refunds work?

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

Skyflow: How does it help with data localisation?

Records can be pinned to a specified region, so an Indian or EU residency requirement is met by the vault rather than by you running regional databases and operations teams.

Volt: Which markets are covered?

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

Skyflow: Can I still run analytics on vaulted data?

Partly. Aggregates and comparisons are supported through polymorphic encryption and secure functions, but arbitrary joins against other datasets are harder than they were, and this is the most common late surprise.
