Billing & fees
Prepaid, and only for trades Kardlane handled successfully.
- The fee is a share of your profit on a successful trade:
fee rate × (vendor rate − customer rate) × value. It’s reserved from your balance when the card is sent and charged when the trade succeeds. - Failed trades are free. So is anything that failed because of us (our system, or the AI being unavailable).
- Verified successes are charged even if a trade is later marked failed or handled outside — the agent confirmed the vendor paid.
- Partial trades: the fee applies to the verified-redeemed cards only, however the trade is resolved.

Top up from the dashboard’s Billing page. Below the low-balance level you get an alert; below the minimum, new trades go straight to review instead of being handled, until you top up. Each trade’s page shows exactly what it cost.
