The short version

  • Only Convoy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Convoy the default deployment is self-hosted, so you operate Convoy plus Postgres and Redis and carry the on-call burden for the system that delivers your customers' events.; 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: Convoy covers Inbound and outbound, 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.

Convoy

  • The default deployment is self-hosted, so you operate Convoy plus Postgres and Redis and carry the on-call burden for the system that delivers your customers' events.
  • Frain Technologies is a small startup, and putting customer-facing delivery infrastructure on it means accepting real vendor continuity risk on a component that is hard to swap out quickly.
  • The premium tier at a flat 999 US dollars a month is poor value below substantial volume, while the community edition omits the portal, transformations and RBAC that most production deployments end up wanting.
  • The hosted cloud trial is capped at one project and 100 events a day, which is too small to properly evaluate the service before committing.
  • Documentation and the third-party ecosystem are thinner than the established webhook services, so unusual configurations often mean reading the Go source.

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.

Volt: How do refunds work?

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

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

Convoy: Do I have to self-host?

No, there is a hosted cloud, but the trial is capped at 100 events a day and self-hosting is the primary model.
