How do we book an imported laptop into our expenses?

A staff member of ours purchased(with his money) a laptop while on a trip abroad. The boss said the company will bear the expenses of it. The laptop was purchased in Singapore. A bill is available in Singapore currency in his name. He however has not paid any customs duty for it since he wasn't frisked/asked. How does one go about accounting this entry and what is the right way of reimbursing the money paid to the employee?

Thanks in advance for any help you are able to provide.
