Try to get the ear of the CEO or CFO of the company.

Explain in a few minutes how major tech companies now take it.

Explain set up a free coinbase wallet and sweep the btc into whatever fiat they want so their bank gets the value in the fiat they want event though you paid CB with crypto.

Once a CEO or CFO is properly 'informed' their resistance to bitcoin drops. Its an acceptable way to take crypto and do sweeps into fiat with many companies now.

Once a company understand services such as CB don't have to 'hold' the bitcoin, it can be converted and deposited to fiat, the risk factor becomes minor.

Sure CB could close tomorrow, but they're emerging as the main corporate gateway for bitcoin/fiat sweeps.
