This account is for individuals to send or receive personal payments to their digital wallets. Once received they can transfer them out to their bank, PayPal, Digital Gift Cards or Digital or Plastic VISA Card. More Info on a personal account.
Note: If you are an individual with a small business you can also use a personal account.
This account is for companies wanting to receive or make payments, build applications using the XTRM API or companies receiving 'Employer' payments from another company. If you create a company account it will require approval and you will be the master admin for that company account. The master admin can login and review transactions and reports plus run payment programs and a lot more. More Info
