Error: GUID is already in use

Show expandable text

Scenario

You might see this error when processing credit card and ACH payments through Practice CS.

Error message

GUID is already in use

Cause

This error means that the client you're processing has the same client ID as another one of your clients. This can happen if you have multiple firm databases.

Solution

To resolve this error:

  1. Make a list of clients that share a client ID who you will process payments for.
  2. Contact Practice CS Support at 800.968.0600.
  3. Support will work with you so you can process payments for the clients.

To avoid this error in the future:

  • We recommend that you use a unique client ID for every new client in Practice CS.
  • You must 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.

Why this issue happens

Each client is assigned a unique identifier on the back end. If the client ID and the unique identifier does not match, the transaction will not complete successfully. So, 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.
