Customize PDF invoice output

First of all you can create one page PDF document with empty space where aMember will output invoice information and upload it in PDF Invoice configuration page (Custom PDF template for invoice).

Then specify Top margin - How much [pt] skip from top of template before start to output invoice.

In case such customisation ability is not enough for you, you can customize of aMember output as well.

There is 4 hooks to customize pdf invoice without change core files:

2 hooks to alter left and right column before table with info

/**
 * @param stdClass $col
 * @param User $user
 * @param Invoice $invoice
 * @param InvoicePayment $payment
 */
Am_Event::PDF_INVOICE_COL_LEFT;  //allow to customize left column with data before table
Am_Event::PDF_INVOICE_COL_RIGHT; //allow to customize right column with data before table

You can put the following code to site.php file and this customization will not be affected by upgrade.

Am_Di::getInstance()->hook->add(Am_Event::PDF_INVOICE_COL_LEFT, function (Am_Event $event) {
    /** @var $payment InvoicePayment */
    $payment = $event->getPayment();

    $col = $event->getCol();
    //print_rre($col); //you can uncomment this line and see what is present in $col object
    $col->add('Invoice Number: ' . $payment->pk(), 'invoiceNumber'); // alter some line
    $col->remove('date'); //remove line
