Small business website advice, Buffalo edition

In Buffalo, 6.6% of workers walk to their jobs and 0.0% take public transportation, a rare share for South Dakota. In a dense, walkable place, location and hours matter as much as price. Hours have to be right, because people walk over after checking them.

Climate normals for Buffalo

Buffalo weather, in normals: July highs around 86°F, January lows around 11°F, measured at Buffalo Asos, 1.3 miles away (1991-2020). About 13 inches of rain and melted snow fall in a normal year, most of it in May. The high reaches 90°F or more on about 30 days a year, and the low falls to freezing or below on about 172 days. A dry climate favors irrigation, xeriscaping and pool service, and water rules are a common question. A website that changes with the season helps: new hours, a seasonal service, a storm notice, sent by email and included in the monthly fee.

These are some of the South Dakota and federal rules a small business with a website runs into:

  • Selling to customers in other states? Each state sets its own threshold for remote sellers; South Dakota’s is More than $100,000 in gross revenue from sales into South Dakota in the previous or current calendar year (the Department’s page lists no transaction-count test). Official source
