Everything about your subscription is self-serve, from your account. No long-term contract, no call to cancel. ## What you can do * **Change plan** — move up or down as your needs change. Upgrades take effect right away; downgrades apply at your next billing date. * **Update your card** — change your payment method anytime. * **Download invoices** — view and download your billing history. * **Cancel** — any time, from your account or by emailing [support@slingso.com](mailto:support@slingso.com). ## Good to know * Billing is in **US dollars**. * On an upgrade, your coverage expands immediately — the agent starts working the extra products, questions, and engines on your next run. * On a downgrade, anything above your new plan's limits is **paused automatically** — the extra products and scenarios, keeping the ones you've tracked longest — and you're told exactly which. Nothing is deleted; resume them once you're back under your limit or move up again. See what each tier covers before you change. Need a hand with anything billing-related?
