Common problems we solve
- Buyers hesitate on digital products because there's nothing to inspect
- Marketplaces (Gumroad, Etsy) take 10–30% of every sale
- Generic checkouts ask for shipping address on a $9 download
- You have no way to add an order bump or post-purchase upsell without engineering
Why cartt.io
0% platform fee
Stripe processes payments to your own account. Keep ~96.4% per sale after Stripe's processing. On a $97 ebook, that's ~$93.50 in your pocket.
Instant delivery messaging
'Instant access after payment' as a built-in trust signal. Buyers see the delivery promise at the friction point — right next to the pay button.
Minimum-field checkout
Email + payment. No shipping address. No phone. No company field. Every removed field adds ~1–3% to completion rate.
Order bumps + post-purchase upsells
Add a $19 bonus pack at checkout. Pitch a $97 upgrade after payment. Built-in, no apps.
Real urgency
Cohort countdown timers for launches. Early-bird pricing windows. Limited-quantity tracking. Real urgency, not fake reset-on-refresh timers.
Hosted file delivery
Upload your digital files. We host them. Buyers get a unique download link by email. You can update files anytime — buyers always get the latest.
