I've missed a payment an account out of action so need it back on ASAP

Thanks for posting here, @daniel-eliteston. 

May I know further details about the missed payment? Any additional information is a great help so I can provide you with an exact and timely solution. 

In the meantime, I've added these articles that you can open for guidance about processing payments in QuickBooks Online (QBO):

• Enter bills and record bill payments in QuickBooks Online

• Record your payments to credit cards

Feel free to get back here and add more details about your concern. I'll be always around to assist you. Take care.
