You defined the minimum value for the field to be 0. So it's never going to show you a negative number, remove min="0"

Thank You alen for this tip. I removed min="0" but it did not have any effect. I also removed the 'placeholder' and 'step' entries. Now I have: <input name="amount" type="number" value="{{ $invoice->left() }}" class="form-control" wire:model.lazy="values.{{ $invoice->id }}.amount">

The browser´s code inspector shows: <input name="amount" type="number" value="655.85" class="form-control" wire:model.lazy="values.5705.amount">

The page in the the browser shows an empty input. Somewhere Laravel/Livewire seem to block the value.
