Local competition in Tarentum

ZIP code 15084, which covers Tarentum and the area around it, had 251 business establishments with employees in 2023. Here is part of that mix, with what each website should show:

  • 4 furniture stores: product photos by room, store hours and, if you want, an online store with the same monthly fee.
  • 7 plumbing, heating and air-conditioning contractors: emergency availability in plain words, the towns you cover and license information.
  • 12 full-service restaurants: the menu, the dining room, private-event information and the hours, kept current by email.
  • 4 beauty salons: services with prices, photos of real work, the stylists and the hours.
  • 3 child care centers: ages served, hours, tuition or fees and how to schedule a tour.

Allegheny County as a whole had 33,812 employer establishments in 2023 and another 91,967 nonemployer businesses, the one-person shops and independent contractors that often have no website at all.

Tarentum’s working residents are concentrated in manufacturing (15.6%) and professional, management and administrative services (11.9%). For any of them, a clear website is the difference between being compared and being skipped.

Weather in Tarentum: plan the website around it

By the 1991-2020 normals of the Salina weather station (13 miles from Tarentum), July highs average 83°F and January lows average 20°F. Precipitation totals about 46 inches a year, with June the wettest month. The high reaches 90°F or more on about 10 days a year, and the low falls to freezing or below on about 140 days. Winter reshuffles demand: snow removal, heating and ice-dam repairs in the cold months, yard work and construction once it thaws. A website that changes with the season help: winter hours, summer specials, storm-season notices, sent by email and included in the monthly fee.

The legal basics for Tarentum businesses online

Some homework before launch:

  • 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 Tarentum, that means asking Allegheny County and the Borough of Tarentum. Official source
  • If you send marketing email from your new business address, the CAN-SPAM rules (16 CFR Part 316) apply, including an easy way for people to opt out. 16 CFR Part 316
  • Out-of-state sellers have to collect Pennsylvania sales tax once they reach the state threshold: At least $100,000 in annual Pennsylvania gross sales, measured by calendar year; there is no transaction-count test. Sales and Use Tax Bulletin 2019-01; Act 13 of 2019
