Looks like the client provided binance address and thats why its not showing on blockchain but actually transfered internally from Binance account to binance account. Sent client internal transfer ID and they are now checking there binance account, once they confirm, we are all set.
Thank you all these amazing people here on the forum.
Exactly, just provide the transfer or internal transaction ID to him and tell him that the transaction went successfully. Now that this is all set and good, you might want to lock the thread.
