Solving the Hoover Tractor INVOICE issue

Using an Accessor in order to pad the INVOICE when calling it from a relationship. But this breaks other relationships where the INVOICE is standard without padding Currently looking into something like so

public function order(): BelongsTo  
{  
    $this->INVOICE = Str::padLeft($this->INVOICE, 15);  
    return $this->belongsTo(Order::class, 'INVOICE', 'INVOICE');  
}

Did not like this at the end of the day
