My husband miscalculated at the construction site this year. what can I do?

Isn't your husband very clear about the accounts? I think it's better to talk to the leader first and see how to solve it. Secondly, I think it is better to find a correct settlement method. There are many people on the construction site, and the accounts are even more complicated. It is not enough to keep a notebook. You can take your husband to the construction site. A clerk, as long as he records at ordinary times, generally won't make mistakes.
