How do DAOs pay for IRL costs

I'm planning to create a social DAO that hosts real-life events periodically. So basically, I could pay for something in real-life (e.g. catering) through a crypto transfer or sending the crypto to my wallet, exchanging to fiat, sending it to my bank account and paying for the costs. However, most businesses don't have a cryptocurrency wallet yet and the latter defeats the purpose of DAOs where everything is democritized and there is no hierarchy in groups.

So my question is, is there a way to make real-life payments through a DAO while ensuring decentralization and transparency?

My knowledge about DAOs is not very extensive so I'm sorry for my ignorance.

Thanks in advance.
