Simoleons are less getting , not having money. Very less pay why?

Make lots of nails and sell them

Which level do you have.  If you are at the beginning, do not expent your city so quick. Demolish existing buildings and build them again.  You will get money for each update and you have not to invastigate additi8nal simeleons into streets and building services. Further you can look in the HQ if there are products offers which are under the maximal sellprice. Buy them and sell them to the highest sellprice.I

One mistake a lot of new players do is buy items from the global market….dont, make and produce them yourself take your time don’t upgrade beyond the capabilities of your utilities and services.
