Hi,

We've made several improvements and additions to our system's invoicing part and payment terms options.

1. The End-of-Month option is available for payment terms now, and it can be set by the company's financial settings on your network (CRM) module.
2. There are some enhancements on the invoicing part, and a DUTY/VAT invoice has been added as an Invoice type. For this type of invoicing, the payment term will be immediate, and otherwise, normal payment terms will be applied to the invoice automatically. 
3. A splitting option has been made available for anticipated invoice items. You can split anticipated items into two pieces according to the unit amount or number of units.  
4. For the invoicing list pages for both sales and purchase invoices, 4 quick filters have been added. 

For more information, please see the attached manual.
