Errors

Error: GUID is already in use

Scenario

You may get the following error message when you process credit card and ACH payments through Practice CS.
Error message
GUID is already in use.

Cause

This client's ID is the same as another one of your clients. This can happen if you have multiple firm databases.

Solution

  1. Make a list of clients that share a client ID you'll process payments for.
  2. Contact Practice CS Support.
  3. Support will work with you so you can process payments for the clients.
To avoid this error in the future:
  • Use a unique client ID for every new client.
  • Use the newer Practice CS database for all new credit card and ACH transactions that must be performed in the new database. If you use the older database to process a credit card or ACH payment, the transaction will not complete.
Internal use only
Work with a Practice CS Consultant to give the list of clients to the TRTA Professional Platform Analysts. Give the customer a turnaround time of 2 business days.
Why this issue happens
Each client is assigned a unique identifier on the back end. If the client ID and the unique identifier doesn't match, the transaction will not complete successfully.
If you process a payment for a client, the CS Payment account will store the client ID and the unique identifier. If you create another client with the same client ID and try to process a payment in the new database, it will have a different unique identifier than what CS Payment has stored, and the transaction will fail.
