Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Thredd

  • Pricing is entirely unpublished, so cost comparison against competing processors requires a sales process.
  • The 2023 rebrand from GPS to Thredd means research under either name alone can miss relevant material, and partner or press references before 2023 will still say GPS.
  • Issuer processing does not include the banking licence itself, so a fintech still needs a separate BIN sponsor or bank partner, adding a second relationship to manage.
  • As shared infrastructure behind many fintech brands, an outage or processing delay at Thredd becomes a simultaneous incident for every programme running on it, with limited visibility for any single customer into root cause.
  • Its verticals span crypto, BNPL and remittance broadly, so depth of specialist support in any one vertical may be thinner than a processor focused narrowly on that niche.

Thunder Client

  • Paid plans are billed annually only: Starter is $3 per user per month and capped at a maximum of 10 seats, Business is $7 per user per month with 500 monthly collection runs per user, and Enterprise is $16 per user per month for unlimited runs
