Change Invoice Created Date equal to Invoice Paid Date WHMCS

1. We need to edit invoicepdf.tpl file to achieve the same. The file is responsible for all the invoices PDF file generated.

2. The file can be found at whmcsfolder/templates/{your active template}/invoicepdf.tpl

3. Find the below code (around line number 64)

$pdf->Cell(0, 6, Lang::trans(‘invoicesdatecreated’) . ‘: ‘ . $datecreated, 0, 1, ‘L’, ‘1’);
$pdf->Cell(0, 6, Lang::trans(‘invoicesdatedue’) . ‘: ‘ . $duedate, 0, 1, ‘L’, ‘1’);

4. We need to replace the above code by the following lines of code :

if(!empty($datepaid)){
$pdf->Cell(0, 6, Lang::trans('invoicesdatecreated') . ': ' . $datepaid, 0, 1, 'L', '1');
}else{
$pdf->Cell(0, 6, Lang::trans('invoicesdatecreated') . ': ' . $datecreated, 0, 1, 'L', '1');
$pdf->Cell(0, 6, Lang::trans('invoicesdatedue') . ': ' . $duedate, 0, 1, 'L', '1');
}

5. Save the file.

Done!!
