The Stripe-native trial capture engine. Verify solvency at signup and capture revenue automatically before the trial ends.
A seamless flow that validates funds when motivation is highest.
User enters card details. Trialock creates a smart hold/pre-auth for the sub amount via Stripe.
The user enjoys the full trial period with zero disruption. The card is already proven solvent.
Shortly before trial end (e.g., 2 hours), Trialock automatically captures the payment.
Subscription activates successfully. Involuntary churn is virtually eliminated.
Handling the payment logic at signup ensures the user is committed. Waiting 14 days for a "cold" charge leads to 10x higher failure rates.
By placing a microscopic hold, we instantly filter out burner cards and empty gift cards that would have churned anyway.
Clear, automated messaging informs the user of the upcoming charge, building trust and reducing chargeback risk.
