Vantaggi
If you're the kind of person who is able to fly below the radar you should be fine. If not you should probably find employment elsewhere.
Svantaggi
Payment Express is dominated by the owner of the company Andy Cullen. I work in the accounts/logistics team so have gotten a better understanding of his nature than most over the years. He doesn't treat anyone well. I think the Trump comparison is appropriate. Andy is probably more intelligent than Trump because he knows how to use a computer but they both lack any moral compass and lack the ability to experience empathy. Andy has repeatedly racked up huge accounts with suppliers only to flip out and demand huge discounts based on the vague promise of continued business. Andy has also received advice from employment lawyers on how to terminate employees arbitrarily using the excuse of "restructuring". If you ever receive such an email from a senior staff member, your fate has already been decided.
