Running a website from Cosmopolis: the Washington rules

Selling or advertising online brings no special license, but a few apply to many Cosmopolis businesses:

  • Many Washington cities license businesses, and those city licences are added to the state business license as endorsements, each with its own fee and extra processing time. In Cosmopolis, that means asking Grays Harbor County and the City of Cosmopolis. Official source
  • Washington’s state retail sales tax rate is 6.5%, with a local rate added depending on the city or county. Washington State Department of Revenue
  • Under the Americans with Disabilities Act, businesses open to the public must make their goods and services accessible to people with disabilities, and the Justice Department’s guidance says that includes their websites. ADA.gov guidance

Each business is different; this is general information, not legal advice.

Cosmopolis web design FAQ

Can my website list the towns around Cosmopolis that I serve?

Yes. List Westport, Hoquiam, Montesano or any other place you work on a service area page, and every page keeps the contact form.

Can the website be an online store?

Yes. An online store with catalog, cart and online payment costs the same $89 a month as a regular website; sales tax is yours to collect (Washington’s state rate is 6.5%, and local taxes may apply).

Does a small business in Cosmopolis need a website?

Your market is bigger than the city: Grays Harbor County has 3,707 nonemployer businesses and 1,558 with employees (2023), and customers search across the whole area. A website is how people outside Cosmopolis find you.

Is there a setup fee?

No. No setup fee: you only pay the $89 monthly fee, after you approve your website. There is no lock-in contract either: you can end the service whenever you need.
