What solution do you use for institutional/company off-ramp?

Hi everyone! Wanted to share my experience related to signing up my company to take crypto as a payment.
Basically we have a web2 & web3 consultancy company. Revenue in the 6 figures per year, so we decided to provide our customers with possibility to cover via crypto payments (stables, btc, eth).

For the past 4 weeks, we've tried signing up our company to a cex (centralized exchange) so that we can "cash out" any crypto to FIAT whenever needed to pay bills etc.

We've tried all major ones such as: Binance, ByBit, Kraken, etc. and 1 month later nobody has approved our KYB request or our account. We've even opened support tickets to ask for updates, only to receive no updates.
