Construction cost monitoring - how do you do it?

Hello! We are in the middle of the construction phase and a lot of invoices are coming in (single awarding of trades). Now my question to you: How do you monitor your expenses? Have you created your own Excel sheets or are there recommended links where one can find a kind of pre-made document? I would like to record all possible expenses so that at the end of the construction period I can quantify the total costs (all inclusive, also catering on the construction site, tips, tool purchases, fees etc., which one often tends to overlook...). Thank you very much for your help! MeisterBob

We have created a simple Excel table. It is only about expenses for various items (which you can, for example, group in blocks).

Excel or another spreadsheet program is the tool of choice here.
Those who are not afraid to entrust their data to Google can use Google Docs. Then you always have the list on hand.
That’s how I did it anyway.

We also have an Excel table with the following columns
- original planned figures
- adjusted plan based on the availability of concrete offers or invoices.
- ACTUAL (already paid)

I also have Excel. I have columns with accounts and what goes to whom for what purpose and when. This way I also have control over savings books, what was deducted from the checking account and what is gone from the big pile. To have constant access, I uploaded the file to Dropbox and can access it anytime from my phone, tablet, or other PCs. So far, for me at least, this is the most efficient method to always be up-to-date.

Planned figures and blocks such as interior construction, outdoor facilities, incidental construction costs, etc. I have also incorporated and equipped with formulas. This way I always know immediately what is still available and where I currently stand.
