# What should I do if my cryptocurrency payment is slightly underpaid and the invoice expires?

If your crypto payment was flagged as underpaid (e.g. due to exchange fees being deducted from the sent amount) and the invoice has since expired, contact support and provide the following details in text format:

1. Your full name and email address
2. Your 7-digit order number (if available)
3. Transaction ID / Hash (TXID) — the long string of letters and digits found in your crypto transaction history
4. The wallet address you sent the payment to
5. The network used (e.g. BEP20, TRC20, Polygon)

Once the team verifies your transaction, your account will be manually processed and sent to you. You will receive an update via email. Always ensure you send the exact invoice amount to avoid underpayment issues — note that some exchanges deduct network fees from the amount sent, which can result in a shortfall.

**If the missing amount is below the minimum transfer limit (e.g. 0.01 USDT when the minimum withdrawal is 5 USDT):** Do not attempt to send the difference. Instead, contact support with your transaction details — the team can manually review and process your payment without requiring the additional amount to be sent.
