Whmcs custom invoice template

To configure WHMCS with a custom invoice numbering sequence:

1. Go to Configuration ( ) > System Settings >Tax Configuration
2. Toggle Tax Support to On.
   
3. Toggle Custom Invoice Numbering to On.
   
4. For Custom Invoice Numbering Format, enter the invoice numbering format to use. You can enter characters that will appear in the invoice number that the client will see and additional tags that the system will replace with a value when generating the individual invoices. You can use the following tags:

• The Next Invoice Number value.
• The four-digit year value for the current date.
• The two-digit month value for the current date.
• The two-digit day value for the current date. For example:
• ABC- would generate invoice numbers like ABC-1234 , ABC-1235 , and ABC-1236 .
• --~ would generate invoice numbers like 21-06-2023~1234 , 21-06-2023~1235 , and 22-06-2023~1236 .
• IND/ would generate invoice numbers like IND/1234 , IND/1235 , and IND/1236 .

1. For Next Invoice Number, specify the number to assign to the next generated invoice.
   
2. Click Save.

The next invoice that WHMCS generates will use an invoice number with the custom format and number sequence that you specified.
