Adding a card
Billing → Payment methods → Add card.
Enter card details — handled by our PCI-DSS Level 1 PSP, helodata never sees the PAN.
The card is verified with a $1 hold that's released immediately.
Default vs backup
You can store multiple payment methods. Mark one as default — that's the one charged for subscriptions and auto top-ups. Backups are used only if the default fails.
We recommend at least two on file: a primary card and a backup. A failed default during a renewal cascades into a 403 account-suspended on the gateway if balance also runs out.
Wire transfers
For Pro+ plans, wire instructions appear on each pending invoice:
Funds clear in 1–3 business days for ACH, 1–5 for international SWIFT. We email when received and apply to balance.
Wires for amounts >$10,000 typically include a small fee on your bank's side — factor that in.
Cryptocurrency
USDT / USDC payments are processed via a self-service flow:
Billing → Payment methods → Crypto top-up.
Choose amount → choose chain (TRC-20 cheapest fees).
Send to the one-time address shown — do not reuse, the address changes per payment.
Balance is credited after 1–6 confirmations (typically <1 hour).
Refunds for crypto top-ups are paid back in the same currency, to the source address; allow 3 business days.
Updating a card
If your card was reissued (same number, new expiry), the PSP usually auto-updates via card-network refresh. Otherwise:
Payment methods → {card} → Update expiry / CVV → re-verify with a $1 hold.
Removing a payment method
Click the trash icon. You can't remove the last payment method if you have an active subscription — cancel the subscription first or add a replacement.
Currency-method matching
Card networks settle in your card's native currency; we display the equivalent in your default currency (set in Address & tax). Cross-currency charges may incur a small bank FX fee.
For lowest cost: keep your billing currency aligned with your card's currency.
API
Cards can't be added via API for PCI-DSS reasons — that flow has to go through the hosted dashboard form.
Common pitfalls
Card auto-renewal failure — most often an expired card. Set a calendar reminder for your card's expiry month.
Wire without reference — without the invoice reference in the wire memo, our reconciliation team has to manually match — expect 1–3 days extra to credit.
Wrong chain for crypto — sending USDT-ERC20 to a TRC20 address loses the funds. Double-check the chain before sending.
