RapidHVACParts review for Invoice Falcon

We have had issues with the app showing that customers still owe .01 after fully paying for their order. This isnt the end of the world but we have customers asking if they need to pay that .01, etc. so we reached out to invoice falcon support multiple times with examples of the issue, asking for help to resolve it and did not hear back so we have now uninstalled and replaced it with order printer pro.
