Billing questions
Is there a setup fee?
No. Self-serve setup takes minutes. Business plans include a guided onboarding call.
Can we change plans later?
Yes, upgrade or downgrade any time from the billing page; Stripe prorates automatically.
What counts as a root domain?
A registrable domain like example.com or example.co.uk. All of its subdomains are included, up to your hostname limit.
What happens after the trial?
14 days, full Pro features, no card required. If you don't pick a plan, monitoring pauses and nothing is charged. Your inventory stays saved for 30 days.
Can I lock in a plan early?
Yes. Pick a plan during your trial and you won't be charged until the trial ends. Do it in the first 10 days and we add 7 extra free days on top. Cancel any time before the first charge and you pay nothing.
Can we pay annually or by invoice?
Yes. Annual plans include two months free. Business customers can pay by invoice — contact us.
