The Default Settings here is to set the prefix and starting running number for vouchers in the Customer module, and configure other default codes.
Note: The default settings here are actually for the Default/Credit Settings tab for each customer in the Customer Master!
1. Set the starting running number for Sales Entry, Cash Sales and Customer Receipt.
2. Enter the default GL or tax codes.
(Make sure that they were not in use previously or there will be an overlap)
3. Set default department, job and salesman code
For example, when you create a new customer in the Customer Master, then the GL codes that are selected for Debtor Control Account and Sales account under the Default/Credit Settings tab are 12100 and 51100 respectively [in red box].
