Indicate discount for submitting invoices to the bank

We are currently diligently using up our equity. Now we would like to submit the first invoices that have accumulated to the bank. Soon it will be time to draw down the construction financing.

Now to the question: we have often negotiated and taken advantage of discounts. Do we now provide the bank with the actual amount paid (i.e., invoice amount minus discount) or the invoice amount? The latter would of course be preferable for us, as it would give us some buffer for later (even if the discount only saved small amounts).

We couldn't find anything about this on Google or in the documents, but maybe someone here knows more about it?

Thanks and best regards!

The bank sees the actual debits from the account, taking into account the discount. My bank generously rounds up odd amounts. You can also ask for, say, [5.000€] for small expenses, as individual invoices would be too much effort.

She does not see it with us, the equity came from accounts at other banks. Hence the question...

Well then, there will surely be a request for a transfer receipt.

I have always summed up the original invoice amounts in the payment request. The invoices had to be attached for this. If a discount was directly shown on the invoice and deducted by the craftsman (rarely), of course that amount applied. Always what is "bottom right" in the original was stated.

This way, discounts and cash discounts flow into your pocket and it also solves the problem of withholdings. If you start to also pull those out of the invoices, you could take years until full payment and go crazy with the receipt chaos.
Our house construction consisted of about 150 invoices. The bank already groans enough having to collect all the invoices, no one wants to see transfer receipts there (I wouldn’t know why either).

Similar with us. The bank never wanted transfer receipts. Only the invoice and occasionally a construction progress report from the architect.
