Click on the "Accounts Receivables" tab, then click on the "Aging / Statements"  sub-tab. This will bring up the "Aging" report which lists all customers with their current open balances and open credits.

Select all customers by clicking the check box on the grid. 

 Click on the "Send" button above the grid, select the "End Date" and click on "Send". The system will create a PDF file of the statements for the customers that were selected and will fax or email them to your customers. 

The information on the statements is based on the transaction date and not on the date when the transaction was entered into the system.

When the user runs an on-screen aging report for a past "As Of" date, the aging information shown will reflect the reality of the customer's account based on all transactions that were entered with a transaction date less than or equal to the "As Of" date specified in the search. This applies to all transactions that affect the customer's balance such as invoices, credits, payments, open credits, discounts, etc.

You cannot generate past statements for any customer if they don't currently have an open balance for that period.
