How can I get previous customer balance in current bill?
What do you mean? Are you looking for variable for the purpose of customizing the look of the invoice?
Yes, customize the invoice or I need to show customer previous balance due + current payment and balance outstanding in invoice.
There is currently no variable which contains customer balance. I’ll have a look at it soon. For now, you will need to send customer statement to show the outstanding balance.

@lubos any news on this feature?
Nothing has changed. If you want a customer balance, create a Customer Statement.
Hello! Any news about this feature? I need this feature by the apartment association invoices. Cos people pay who knows what kind of amount and its always a headache to clear unpaid invoices. Also im tired to send every month around 100 customer statements 
Any news on this @lubos ? Even knowing the variable to use it in custom themes will suffice for now.
@BawarYassin, if you read the entire thread, you will see there is no such variable for sales invoices. Themes can only change the appearance of the invoice, not the content.
@Tut, And if you check the date, you will see he said “currently” seven years ago. I was hoping for an update on this.
There’s still no such variable. All the variables used are included in the default “Plain Theme”.
