kg1972 You would need to exchange the Lumens for USD, EUR, .... and send it to your bank account (or pick up as cash if you are located in Paris and decide to use tempo as your anchor). You can do the exchange directly on the stellar network.
Here you can find a list of all anchors:

But why would you like to accept Lumens for payment? The stellar network makes it easy to accept any fiat currency directly and there are some anchors with support for CNY, USD, EUR, NGN, ...
Depending on where you are located maybe some of them would work for you.
