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.

Stoplight

  • The free plan allows one project and one user
  • Private projects, multi branch support and custom domains start at the Startup plan, $113 a month billed annually
  • SSO and shared style guides are Pro Team only, at $362 a month billed annually
  • Seats beyond each plan's allowance are $11 to $27 each per month depending on tier and billing period
