I need to be able to send my customers' recurring invoices and have them pay with auto payment (credit cards, ACH, etc). But one of the recurring invoice lines will change value every month. QuickBooks billing/payments can not handle this feature. Seems to me that many businesses besides mine would rely on this a great deal - utilities, etc - any business with variable charges. Are there plans to offer this soon? Is there a work around? Are there better billing systems that have this and integrate with QuickBooks Online?
