No! You can set everything up without writing a single line of code. Just connect your PayPal account, create plans through our dashboard, and share the checkout links. For developers, we also provide a simple API.
No. All payments go directly to your PayPal account. We never touch your money. We just make it easier to set up and manage PayPal subscriptions.
PayPal charges their standard rates (typically 2.9% + $0.30 per transaction). SenSub doesn't add any transaction fees on top—you just pay the flat monthly subscription.
Yes! SenSub works with any existing PayPal Business account. Just connect it in the dashboard using your Client ID and Secret. All your existing plans, transactions, and customer data remain in your PayPal account—we just add the management layer on top.
Stripe is great, but many international users and some market segments prefer or require PayPal. SenSub allows you to offer PayPal subscriptions as easily as if you were using Stripe, without needing to maintain complex PayPal integration code.
We'll notify you when you approach the limit for your current plan. New subscriptions will be paused, but existing subscriptions will continue to be managed without interruption. You can upgrade instantly in your dashboard to continue accepting new subscribers.
Get your first PayPal subscription customer in less than 5 minutes.
