Is there a payment method available?

We provide services to United States citizens while operating remotely. To establish trust and facilitate smooth business transactions, we have represented ourselves as being based in the US.
Currently, we wish to send an invoice for our services; however, we lack an account that is commonly used in the US. Is there a payment method available that would allow us to send invoices, enabling them to pay using their credit cards or banking applications?
Subsequently, we would like to withdraw the funds to our accounts in our country.
