After you've signed up a business account with Paypal you'll want to connect your business bank account to it so you can transfer money from the Paypal account to your regular bank account. This is obviously so you can get at the money.
1. Log into your newly created paypal account at their website.
2. On your My Account page there'll be a button that says Profile. If you put your mouse on it other menu items will show up, you should click on Add Bank Account.
3. Simply put in all your details and click continue. Note that you won't be able to put in your bank account name here; Paypal assumes it is the same as your business name. If it's not the same you shouldn't continue with the bank account set-up because it will fail. You should instead terminate your Paypal account and set up another one with the correct business name details.
4. In a few days check your bank statement for two small deposits made by Paypal. When you have these details return to your Paypal account and put in these amounts where indicated and it should be all confirmed.
Next step is to get your logo onto the Paypal page that your customers will see. Please read the following FAQ for how to do this.
