[marcoboers]

How can I set the VAT on the created invoice? Or make make a certain tax rate the standard of a new invoice?

You should be able use:

$invoice = new Invoice();
$invoice->client_id = 1;
$invoice->addInvoiceItem('Item', 'Notes...', 10);
$invoice->tax_name1 = 'VAT';
$invoice->tax_rate1 = 17;
$invoice->save();
