General Business License

Wisconsin does not have a statewide general business license. Businesses must register their entity with the Wisconsin Department of Financial Institutions and register with the Wisconsin Department of Revenue for sales and use tax and withholding tax purposes. Some Wisconsin municipalities require local business licenses, though this varies. Milwaukee, Madison, and Green Bay have their own licensing requirements. Wisconsin's one-stop portal at DFI.wi.gov helps streamline business registration.

4
Not building service agreements with property management companies — recurring commercial work provides stability
5
Neglecting the HVAC and water heater segment — water heater replacement is one of the most profitable single services
