In most practices, check in/out, invoice flags, and sending invoice items back are all controlled by your practice software.
This is most likely because IDEXX Sync (the program that connects your main software to Instinct) is not working at your practice. This means that check ins/outs cannot occur automatically and invoice flags will not be accurate.
If you suspect this, please contact your practice administrator to confirm (and fix). You can ask them to “restart the Datapoint Services” on your server (not the server itself, just restart the Datapoint Services). If that doesn’t work they may need to reach out to IDEXX to get it working. Their standard support hours are 7:00 AM – 4:30 PM Central Time on Monday through Friday.
