About

Turn every Cardmarket order into a ready-to-send PDF invoice — without copy-pasting, without spreadsheets, without accounting software.

JellyBill is a browser extension built specifically for Cardmarket sellers. Open any order page, click JellyBill, and your invoice is ready in seconds.

HOW IT WORKS
────────────────────────────────────

1. Open a Cardmarket order in your browser.

2. Click JellyBill in the side panel or use the button on the order page.

3. Review the items, buyer details, and totals.

4. Download your PDF invoice — done.

JellyBill automatically reads product names, quantities, prices, shipping costs, and the buyer's address from the order page. You set up your business details once — and JellyBill reuses them on every invoice from that point forward.

WHY SELLERS USE JelllyBill
────────────────────────────────────

► Saves time
No more manually copying order data into Word, Excel, or any other tool. JellyBill reads the order page for you.

► Looks professional
Clean, well-structured invoice layouts your customers will appreciate — and that hold up for your own records.

► Scales with you
Works equally well for hobby sellers who ship a few cards a week and for high-volume shops that invoice every single day.

► Stays organized
Invoice numbers and your seller profile are stored in one place. No more searching for last month's invoice.

► Built specifically for Cardmarket
JellyBill understands real Cardmarket order pages — it's not a generic template you have to fill in yourself.

► Cloud sync
Sign in at jelllybill.com to sync your profile across devices and access your invoice history in your online dashboard. Paid plans offer more invoices per month.

PRIVACY & PERMISSIONS
────────────────────────────────────

JellyBill only activates on Cardmarket order pages and on jelllybill.com when you use the dashboard. It needs permission to read the order page you have open so it can build the invoice from that data. No data is collected or shared beyond what is described in the privacy policy at jelllybill.com.
