Hide payment options?

[everclean]

Hello,

I have a Shopify store that sells services. I already have a custom payment method that allows customers to pay later. But is it possible to make this the only way to check out, and then later pay via the payment invoice that I send to the customer? If I want the credit card & mobilepay options to be hidden during checkout and available at checkout via an invoice?

thank you in advance.
