error units in invoice

Hi @izquierdocreativo,

Could you please show me a screenshot of the details from a test order, and its PDF invoice? You can use imgbb.com to upload the images, and then share their URLs here.

To clarify, this is the order details I refer to:

The problem from what I see is that woocommerce does not respect the purchase of fractional products and has done what it wanted. The invoice plugin respects what woo says.
Sorry for the inconvenience and thank you very much for your reply.

You’re right. This is the default behavior from WooCommerce. However, some plugins enables the decimals in the quantity field.

If you need to allow this in your store by yourself, without any plugin, you could use this code snippet, that seems to be working yet:

// Add min value to the quantity field (default = 1)
add_filter('woocommerce_quantity_input_min', 'min_decimal');
function min_decimal($val) {
    return 0.1;
}
 
// Add step value to the quantity field (default = 1)
add_filter('woocommerce_quantity_input_step', 'nsk_allow_decimal');
function nsk_allow_decimal($val) {
    return 0.1;
}
 
// Removes the WooCommerce filter, that is validating the quantity to be an int
remove_filter('woocommerce_stock_amount', 'intval');
 
// Add a filter, that validates the quantity to be a float
add_filter('woocommerce_stock_amount', 'floatval');
 
// Add unit price fix when showing the unit price on processed orders
add_filter('woocommerce_order_amount_item_total', 'unit_price_fix', 10, 5);
function unit_price_fix($price, $order, $item, $inc_tax = false, $round = true) {
    $qty = (!empty($item['qty']) && $item['qty'] != 0) ? $item['qty'] : 1;
    if($inc_tax) {
        $price = ($item['line_total'] + $item['line_tax']) / $qty;
    } else {
        $price = $item['line_total'] / $qty;
    }
    $price = $round ? round( $price, 2 ) : $price;
    return $price;
}

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use filters

Hope it helps!
