How this works: Add offset capacity once. When customers opt in to carbon offsets at checkout, carbon is offset automatically — no action needed per order. Each offset issues a certificate directly to your customer. When your capacity becomes low, we notify you.

💰 How you get your money back — plus revenue

You pay the carbon cost upfront at zero Carbonaa margin. When customers opt in at checkout, your prepaid amount is recovered through customer payments — and you earn a revenue share on top.

1.You pay now — the carbon acquisition cost (at cost, no markup).
2.Customer opts in at checkout and pays the offset fee per order.
3.Principal recovered — your prepaid amount is returned to you through these customer payments.
4.Plus revenue share — you earn 8–12% of the margin on every offset, depending on your tier.

Net result: your upfront payment comes back to you through customer offset fees, and you keep the revenue share as profit. The more customers opt in, the faster you recover your principal and the more revenue you earn.

⚠️ Important: Carbon credits are non-refundable

Upon payment, your offset capacity is activated. Carbon is retired per-order when customers opt in at checkout. These retirements are permanent and irreversible. No refunds can be issued once capacity is activated. Please ensure your quantities and details are correct before proceeding.

What if I purchase too much?

Offset capacity never expires. Your capacity carries forward indefinitely.

What if I purchase too little?

Add capacity anytime. Client orders are tracked and offset automatically when capacity is available.

What happens after payment?

Capacity activates immediately. Carbon is offset automatically when customers opt in — certificates are emailed directly to your customer.

Do customers pay me back?

Yes. Customers who opt in pay the offset fee at checkout — that payment recovers your prepaid principal AND earns you a revenue share on every order. Your upfront cost is returned plus profit.

Will I receive proof?

Yes. Official certificate from Official Registry. Downloadable anytime.
