Beginner question - how to pay an invoice?

This is a complete beginner question. I'm new to the office environment.A company has created a sign for us and they've sent over a proforma invoice with their bank name, sort code, account number and account name.If I send this to our accountant does she have all the details she needs to process it? I'm worried she will start asking lots of questions and I won't know the answers to them. via /r/business https://ift.tt/2MbRCuo
