What happens after the initial contract term
Per Quartix's own Terms and Conditions, the initial contract runs 12 to 36 months as selected by the customer. At expiration, the customer moves to a 1-month rolling contract automatically — not another multi-year commitment — and either party can then give one month's notice to end it.
Within the original minimum term, though, the Terms state plainly that 'the Customer may not cancel or terminate the Contract until the Minimum Period specified in the Contract has expired' — there is no early-exit option described, only the option to wait it out or breach and face termination for cause.
Billing runs via direct debit rather than credit card, which Quartix's FAQ describes as 'a streamlined approach' for predictable payments — a genuine difference from most competitors' card-based billing, worth confirming fits your accounts-payable process before signing.
