Billing, trials and invoices

Paid plans start with a 14-day trial (once per account). A card is required; you are charged at the end of the trial unless you cancel.
Payments, invoices, VAT numbers, plan changes and cancellation are handled in the Stripe customer portal (Billing → Manage subscription).
Prices exclude VAT. Add your VAT number at checkout; where applicable, EU business customers are invoiced under reverse charge.
If a payment fails, Stripe retries automatically and monitoring continues meanwhile. If the invoice remains unpaid, monitoring is paused automatically and resumes as soon as it is paid.
When you downgrade, stores above the new limit are paused (newest first) and reactivated automatically if you upgrade again.
