- No payment processor migration required
Every offset option and pledge, tracked in one place
Create and manage offset options, then confirm and retire every contribution shoppers pledge — with a real-time view of participation and impact, no spreadsheets required.
- Create, edit, and pause offset options in seconds
- Respond to pledges: confirm, decline, or mark retired
- See total contributions and impact at a glance
From pledge to retired credit — fully tracked
Every contribution moves through a clear lifecycle, so merchants and shoppers both know exactly where their money went.

Questions merchants ask us
Do you process payments directly?
Green Cart Pass tracks the offset option a shopper chooses and the pledge it creates. In production, the contribution amount is added to the order and settled through your existing payment processor — we don't hold funds ourselves.
Which offset providers do you work with?
Merchants can list options for reforestation, renewable energy credits, verified carbon credits, and ocean plastic cleanup, each backed by a project of your choosing.
How long does integration take?
Most merchants are live the same day: create an account, add your first offset option, and it's ready to appear at checkout.
Can I change pricing later?
Yes — edit the price, impact unit, or status of any offset option at any time from your dashboard.
