Should the interior plaster/staircase and entrance door area be billed separately?

Hello everyone,

I need your help!!

The following problem:

The interior plastering in our new building was already completed in January 2014 except for the staircase to the first floor and the front door, as these had not yet been installed. This was supposed to be "touched up" later. The invoice for the interior plastering was also paid in January.
Now a separate invoice for the staircase and door amounting to €238 has arrived with the reasoning that this is usually handled this way, that these areas are not included. This was not mentioned in any of the (pre-) discussions or communicated in writing.
Does anyone maybe have experience with this? Is this separation and separate billing lawful or is the company trying to rip us off??
What should and can we do??

Thank you very much in advance for your answers!!

Hello,

what exactly is stated in the BB regarding interior plaster?

Hello construction expert,

what do you mean by BB?

Description of work.

From my point of view, such a procedure would make sense – if a service has been provided, it should also be billed. If only partially provided, then it should be billed proportionally, but this should also be evident from the invoice. If you spread it out over several years (to take it to the extreme) – it will become very difficult for the contractor at some point. And the wrong approach 'we bill everything at once, but then deliver sometime later' is also not really ideal...

There were a total of 2 invoices. The first was an installment invoice, in the second the item description was "completion of the work," although the stair area was not yet finished. From my point of view, this can only mean that it implies all walls, including the stairs and door, so the third invoice is complete nonsense. Or????

P.S. Unfortunately, there is no construction description, everything was agreed upon orally.
