We are now accepting payments online. All online transactions are charged a 2.9% transaction fee on top of the regular invoice amount. This transaction fee is not added automatically and must be inputed manually on the payment screen. Failure to include the transaction fee while making an online payment will result in further fees from United Micro Data, Inc. until all charges are paid in full. Payments may be made using Visa, Mastercard, American Express, Discover or your Pay Pal account. Simply click on the Pay Now button below.
