In short

Storvexa integrates payment gateways such as Stripe, PayPal and Razorpay into websites and applications: checkouts, subscriptions, invoices, refunds and the webhooks that keep your records in sync. Card data stays with the payment provider, every flow is tested end to end in test mode, and work is billed hourly or monthly after a written estimate.
