@igun997 very weird, it works perfectly for me.

Your error points to this parameter missing:

$this->currency_decimals            = config('invoices.currency.decimals');

Which should be set by default anyway, but maybe something is missing on your end.

Have you done php artisan invoices:install?
If not, please do so.
If you did, please tell me what is the value of your config/invoices.php file's 'currency' => ['decimals' => X]]

[igun997]

'currency' => [ 'code' => 'idr', /** * Usually cents * Used when spelling out the amount and if your currency has decimals. * * Example: Amount in words: Eight hundred fifty thousand sixty-eight EUR and fifteen ct. */ 'fraction' => 'ct.', 'symbol' => 'Rp', /** * Example: 19.00 */ 'decimals' => 2, /** * Example: 1.99 */ 'decimal_point' => '.', /** * By default empty. * Example: 1,999.00 */ 'thousands_separator' => '', /** * Supported tags {VALUE}, {SYMBOL}, {CODE} * Example: 1.99 € */ 'format' => '{VALUE} {SYMBOL}', ],

@igun997 no idea, to be honest, tried with exact same config - copy-pasted your values, I get this PDF:

Maybe try to copy-paste the code once again, and make sure you didn't mix any symbol, maybe some bracket or other symbol is incorrect?

Or, you can put your code to github and attach me as collaborator, then I could debug it for you on your project, maybe.
