Click on the Batch Entry icon.
The 'Type' drop down box in the batch entry form will let you select Cashbook, Accounts Receivable or Accounts Payable entries.
If you select AR or AP, you will be able to enter a customer or vendor number. The Allocation button will only be activated when all these fields have been filled in correctly.
To enter the amount for the receipt or payment, you must enter the first line in the detail section of the batch.
Once you have entered the amount, click on Allocate or press Alt+L to enter the allocation screen.
In this screen you can apply the amount to existing invoices which are displayed in spreadsheet format or you can apply payments directly.
When posting these transactions Cashbook will create the necessary batches in the Accounts Receivable and Accounts Payable systems.
