Payment before or after completion of the construction phase?

I find different things about it and would like to know how this topic is contractually regulated or possibly renegotiated with you.

According to the work contract, we would always pay first and then another construction phase would be completed. Our payments are therefore always ahead.

According to the assessment of a friend with industry experience, this is not unusual, but he would try to renegotiate that. An already paid invoice is no longer a "lever."

How was it with you?

Not only that... if the entrepreneur goes bankrupt, you are left without a roof and without money for the roof... Payment should be made after the service has been rendered.

Would never advance payment either. We have now also received an invoice that is a whopping 50% higher than the service provided so far. This can be quite accurately derived from the offer/order. We will accordingly reduce the invoice and write a letter to the craftsman.

According to the contract, we would always pay first

What exactly does "was" mean?

The law is clear.

[632a Baugesetzbuch]: The contractor is obliged to perform in advance.

Payment therefore after performance.

According to the contract, we would always pay first and then another construction phase would be completed. So our payments are always ahead.

I can hardly imagine that. Doesn't your payment schedule show the trade you are paying for next to the percentages? At the beginning, planning is often listed, so many think that they are making advance payments. Please post your payment schedule anonymously.
