What kind of businesses Rock Valley has

The Census counted 242 establishments with employees in 2023 in ZIP code 51247, which includes Rock Valley and its surroundings. A few examples from the same count:

  • Insurance agencies: 7. Their website should show the lines you write (auto, home, business, life), the carriers you work with and a quote request form.
  • Beauty salons: 5. Their website should show a price list, a gallery of recent work and a contact form for appointment requests by email.
  • Custom home builders: 5. Their website should show a portfolio page per home, the steps of working with you and a contact form for buyers who are still comparing builders.
  • Auto repair shops: 4. Their website should show the services you do, the makes you work on, hours and a form to describe the problem.

Sioux County as a whole had 1,345 employer establishments in 2023 and another 3,024 nonemployer businesses, the one-person shops and independent contractors that often have no website at all. Sioux County has far more than the national share of farm and forestry support services: 18 of them in the 2023 count. In that line of work, farmers book custom harvesting, spraying and equipment work by the season, so the website should show the crops, acres or animals you handle, your equipment and the counties you cover. Next on the list: trucking companies, 124 of them, at about five times the national share. 22.2% of employed residents work in education, health care and social assistance, and 10.7% in retail trade.

What Iowa asks of a business with a website

Before your website goes live, it helps to have the basics of the business in order.

  • The Iowa Consumer Data Protection Act rarely reaches a local business: Businesses doing business in Iowa or targeting Iowa residents that, in a calendar year, control or process personal data of at least 100,000 consumers, or of at least 25,000 consumers while deriving over 50% of gross revenue from selling personal data. A typical small website or online store is far below both thresholds and is outside the law. Iowa Code chapter 715D (SF 262, 2023)
  • Iowa’s state sales tax rate is 6%, and many cities and counties add a 1% local option sales tax on top of it. Iowa Department of Revenue
  • Selling to customers in other states? Each state sets its own threshold for remote sellers; Iowa’s is $100,000 or more in gross revenue from Iowa sales in the immediately preceding or the current calendar year. There is no transaction-count test. Iowa Code 423.14A(3)(a)
