Membership plans (Free vs Pro)

What paid membership adds, and how upgrades, downgrades and cancellation work.

Kartadum has a free plan and paid (Pro) plans that unlock advanced features such as richer pricing and collection tools.

Upgrading

  • Add a payment method before upgrading — paid plans charge your default card or SEPA mandate.
  • There is no free trial; upgrading starts a paid subscription right away.

Downgrading or cancelling

  • Downgrade and cancellation take effect at the end of your current billing period.
  • You keep your current tier until then.
