Hi,
Can we deal directly with a client now, outside SC? I'm not sure, but it seems I read something somewhere about it recently? Maybe in the last update when SC increased the fees... etc.

Today I had a msg from a potential client who wanted to buy my service but he was struggling with the payment processor.

He messaged me to know if I can accept Paypal, and I replied "NO" because I don't have Paypal.

Then I asked him, why aren't you pay through Seoclerk?...
He replied, with a screenshot, that Seoclerk is only showing him two payment processors and he can't pay with both those processors.

Later, I had nothing to help him with - so I had to tell him sorry.
But maybe I could do something directly if I could ask him if he could pay me with Perfectmoney, Payeer, Neteller, Skrill, or any Crypto.

Though, the client last replied he will try with Coinbase. But it seemed to me that it will be a hassle for him.
Maybe a direct crypto payment could be an easier option for him.

Don't get me wrong - just making an inquiry!

Peace!
