Solution:

You should generate the invoice number using mutateFormDataBeforeCreate https://filamentphp.com/docs/3.x/panels/resources/creating-records#customizing-data-before-saving...

Resource

php 
class InvoiceResource extends Resource
{
Forms\Components\TextInput::make('invoice_number')
                        ->readOnly()

                        ->validationMessages([

                        ])
                        ->formatStateUsing(function (Forms\Set $set) {
                            self::generateInvoiceNumber($set);
                        })
