# Customer Inquiry (CUST.Q)
Read Time: 1 minute(s)
The CUST.Q procedure provides an on-line inquiry for a selected customer. The inquiry includes information about the customers open balance, credit limit, sales history, open orders, job status and A/R activity, contacts and the contact log.
The number of days of sales history which is displayed depends on parameters used when running SALES.P2 , a separate procedure that updates sales analysis data. Note that this update is normally setup as as part of the nightly batch processing.
The number of days of A/R activity displayed depends on the setting in ACCT.CONTROL .
Information in CUST.Q is read-only data. You do have the ability to log transactions by using a button provided to add a new log transaction. Log transactions are stored in a separate data file. Customer data should be entered through the customer entry procedure ( CUST.E )
