Customers in an older borough often ask around first, and the website is where that recommendation gets checked. New in town? Then the website has to do what word of mouth does for the older names: show the work, the people and the prices.

Before you publish: Pennsylvania and federal rules
A website doesn’t need a special license, but the business behind it follows the same Pennsylvania rules as any other.
- The name customers see has to be your legal name or a fictitious name registered with Pennsylvania. Fictitious Names Act of 1982, 54 Pa.C.S. §§ 301 et seq. (registration under § 311)
- The Pennsylvania sales tax rate is 6 percent. Only two local add-ons exist: 1 percent in Allegheny County and 2 percent in Philadelphia. Pennsylvania Department of Revenue
- Municipal requirements are separate: check with the local municipality about taxes, zoning requirements, local licenses and permits. In Mount Oliver, that means asking Allegheny County and the Borough of Mount Oliver. Official source
