Before I enter them, I have two credit memo’s from a vendor - I pay them by ACH. Am I able to enter them as I would an invoice with a negative amount, will the system use the credit memo’s automatically, I have not had to deal with a credit memo yet. Thanks for the help in advance 
Good afternoon! Unfortunately, you would not be able to enter credit memos in Ramp unless you use one of our direct ERP integrations (i.e. Quickbooks Online, Xero, NetSuite, or Sage).
I also want to mention that you can’t create bills with a negative amount at this time. However, a potential workaround could be to add a line item to your bill with the credit memo amount. See the example from my demo account below:
Some more info on credit memos can be found here
Hope this is helpful
