Hi Catherine,
thank you for your message!
By default, the plugin shows the date format as Y-m-d (e.g. 2020-07-20)
You may change it by editing your custom invoice template:
For the date of sale you may change the date format by changing this code line:
<?php echo $invoice->getDateOfSale(); ?>
to:
<?php $dateOfSale = new DateTime($invoice->getDateOfSale());
$dateOfSaleFormatted = $dateOfSale->format('d/m/Y');
echo $dateOfSaleFormatted; ?>
or even simpler:
<?php echo DateTime::createFromFormat('Y-m-d', $invoice->getDateOfSale())->format('d/m/Y'); ?>
You may add similar changes for getDateOfIssue and getDateOfPay.
I hope it will be helpful.
Best regards,
