Proforma Invoice

[hostpro2u]

Hi,

 

May I know how is the Proforma Invoice system for WHMCS works? As I read from: http://wiki.whmcs.com/Invoicing, it said

 

Proforma Invoicing

 

The sequential numbering is most often used in conjunction with proforma invoicing. If you want to do this, then you need to make a few template changes aswell to reflect the different names - Proforma invoice when unpaid and Invoice once paid. Instructions can be found in the viewinvoice.tpl and invoicepdf.tpl files where the changes need to be made - just need to uncomment the commented out code you will find in those files.

 

I've uncomment below code, but where can I see the result? it will auto-reflect or I need to do something?

 

<title>{$companyname} - {* This code should be uncommented for EU companies using the sequential invoice numbering so that when unpaid it is shown as a proforma invoice*}

{if $status eq "Paid"}{$LANG.invoicenumber}{**}{else}{$LANG.proformainvoicenumber}{/if}{$invoicenum}</title>

 

Is it possible for me to have Proforma Invoice, Official Invoice, and Paid Invoice together?

 

Thanks.
