As your question is not specific, here's a generic answer - you can send invoices, request payments via PayPal.ME, setup up a web page with either Buy Now, Add to Cart, Donation or Subscription Buttons or send email payment links to customers. Assuming your Business account is setup up properly, you don't really have to do anything - for example, you send an invoice to a person, they pay, the funds minus the transaction fees are deposited into your Account Balance. Same is true if you have a web page setup with Buy Now or Add to Cart item buttons. Customer makes the purchase, completes the checkout process on the PayPal Screens, the money minus the transaction fees are deposited into your Account Balance.
