what determines the bank account that is selected by default on the customer payment?

AI generated answer (using internal Slack threads):

The default bank account that is selected on the customer payment is determined by the settings in the Accounting Preferences. You can set up your default payment account on Setup > Accounting > Accounting Preferences on the Items/Transactions tab. However, this setting applies to all payments, not just certain ones. If you need to set the default payment account by subsidiaries, you can use a client script and a custom record. You would create a custom record in which you enter a bank account for each subsidiary, and then create a client script to apply this setting. Please note that there is no option to set a GL account at the customer level. If you have specific requirements, you could potentially use a workflow to update your account based on those requirements, but this may not always be feasible. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
