As of 2015, the only methods for paying the outstanding balance on a Home Depot credit card is through the mail insert included with the monthly bill or online through the Home Depot Credit Center. Online payments involve creating an account with the site and linking an outside funding source.
After a customer signs up for a Home Depot credit card, she has the ability to create an account with the Credit Center site to manage the card. She can use the Payments page on the site to link a bank account or debit card to process payments. Alternatively, the customer can fill out the balance due form received with each paper statement to mail in payments.
