Can I use Xoom to send money to a business?
Xoom is a person to person remittance service and does not support transactions for goods or business purposes. While you may be able to submit a transaction intended for a business, the transaction will eventually be rejected or the transaction will not be completed as the business receiving the payment will not be able to associate it with an invoice number.
Why can not deposit money with website
We will enable deposit/withdraw sections as soon as we launch. We are working hard to make this happen in the very near future.
