I'm searching for this answer myself. So far one can accept STEEM payments sent to their STEEM wallet here on steemit. So yesterday a client had paid for a t-shirt with steem by sending an ETH payment to the company's ETH->STEEM wallet address via blocktrades (the recommended STEEM buying option on steemit: https://blocktrades.us/?input_coin_type=btc&output_coin_type=steem&receive_address=olkodesign .)

My advice for you & your accountant is to research as much about blockchain technology & cryptocurrencies as possible and to get him interested by informing him as much as you know as well. The technology is the future of money -- it's basically giving the power back to the individual. If I buy a truffle from you and pay you directly via the blockchain (depending on the coin we use,) and I'm located in the U.S. and you're in Italy, then we don't need to pay the fees associated with fiat (i.e., converting USD to Euro, paying a foreign transaction fee by use of a bank card, fees from paypal or sending money with Western Union shudder.) Banking fees is a multi-billion dollar industry.

As far as constructive criticism to your website, I would like to see an active stream of information about truffles. I have never tried one, but your website doesn't do much to convince me to do so. What do they taste like? What exactly are they, a type of fungus, right? I only know about them from an episode of the Simpsons where they were using a pig to snuff the truffles out in the woods.

This is the type of information that is both valuable to your site's ranking and your potential customers. I didn't realize I could buy a truffle for 7 euros. I thought the price range was in the 1,000's. But still, after surfing two or three pages in your site I just exed it out because it left work for me to do on my own to decide I want to buy one. I left not knowing anything more than I came in with. Anyway, beautiful photographs on the site and a lot of potential.

Here's a truffle hog in action:

May your time be spent productively to produce your happiness.
