Subscribing to a plan

Changing plans
Upgrading
You can upgrade at any time. The new plan takes effect immediately and you're charged a prorated amount for the remainder of the current billing period. All new features and limits are available right away.
Downgrading
When you downgrade, the change takes effect at the end of your current billing period. You keep access to the higher-tier features until then. Make sure your usage is within the lower plan's limits before the switch:
- If you have more domains than the new plan allows, deactivate or delete some before downgrading
- Active schedules will be paused if the new plan doesn't support scheduling
- API integrations will stop working if the new plan doesn't include API access
Cancelling
You can cancel your subscription at any time from the Billing page:
- Go to Billing
- Click Cancel Subscription
- Your access continues until the end of the current billing period
- After that, your account reverts to the free trial
Your data (checks, scans, issues) is preserved when you cancel. If you resubscribe later, everything will still be there. However, features gated by your plan (schedules, API access, etc.) will be inaccessible on the free trial.
Resuming a cancelled subscription
If you've cancelled but your billing period hasn't ended yet, you can resume the subscription from the Billing page. This restores the plan without any interruption.
Payment methods
StackShield uses Stripe for secure payment processing. We accept all major credit and debit cards. You can update your payment method at any time from the Billing page.
Invoices
View and download invoices from the Billing page:
- Go to Billing
- Click Invoice History
- Click Download on any invoice to get a PDF
Invoices include your payment amount, billing period, and plan details. They are generated automatically each billing cycle.
Usage limits
Some plan features have usage limits that are tracked per billing period:
- Domain limit — you'll see a notice when creating a check if you've reached your plan's domain limit
- Manual scan limit — free trial users have a limited number of manual scans per period
You can see your current usage on the Billing page. If you need more capacity, upgrading your plan takes effect immediately.
FAQ
Do I need a credit card to start?
No. The 14-day free trial is fully functional without a credit card. You only need to add payment details when upgrading to a paid plan.
What happens after my free trial ends?
After 14 days, you'll need to choose a paid plan to continue using StackShield. Your data is preserved, so you can pick up right where you left off.
What happens if my payment fails?
Stripe will retry the payment a few times. If it continues to fail, your subscription will be cancelled. You can update your payment method and resubscribe at any time.
Can I get a refund?
Contact our support team if you need a refund. We handle refund requests on a case-by-case basis.
