Stacks, basement heaters, and old drains in the close-in neighborhoods are a different visit from a newer suburban water heater. Winter freeze is a real season, not a footnote. In St. Louis, the housing decides the visit: brick houses and basements in the city and close-in suburbs, with a separate newer stock in St. Charles. The weather on the truck is humid summers, cold winters, ice, tornado and hail risk, and clay that moves with moisture. Central West End, Soulard, and Clayton are worth naming only when they are real stops. Kirkwood and St. Charles are a different drive until you can reach them the same day. City of St. Louis permits is the local counter to ask when the job needs a permit or a city registration. This page names that office. It does not invent a fee. The Illinois side of the metro is a different state license. This page is about the Missouri side: the city, Clayton, Kirkwood, and St. Charles. Do not imply one license covers both banks of the river. City customers want a crew that can work an old brick house. Suburban customers want a crew that shows up inside a normal window. Those are different promises.

Start the route in Central West End, Soulard, and Clayton. Add Kirkwood and St. Charles when you can reach them the same day. City customers want a crew that can work an old brick house. Suburban customers want a crew that shows up inside a normal window. Those are different promises.
The Missouri guide has the filing office. This page is the local version: what the first jobs are, which permit counter to call, and how to price a day here.
Some boxes are labeled Partner. ServiceBase has not joined those programs. The links go to each company's own homepage, not a tracking link. If a program later approves us, the address will change and we may earn a commission. You can file, insure, and bank anywhere. Official government links are not partner links.

Keep the checklist on your account
The guide stays public. An account saves your state, city, and trade, and lets you mark each filing as you go. The advertising credit is reserved when you register. It can be spent after the free website is live.
You can start as a sole proprietor if the state lets the license sit in your own name. Form an LLC when you want the company on the license, the van, and the bank account, and when the board's qualifier rules allow it. Read those rules first. An LLC does not authorize an apprentice to pull permits. File with the state before you apply for an EIN if you are forming the company.
We do not have a filing fee for Missouri that we are willing to print. Use the SBA lookup, choose Missouri, and read the fee on the state office's own page. Sole proprietors who operate under their own name often skip this filing. Confirm that on the same site.
If your customers are in St. Louis, the registered-agent address still has to satisfy Missouri. Read the filing office's rule. A neighbor's kitchen table is not always an acceptable address.
An employer identification number is the business tax ID. The IRS issues it online at no charge and says you never have to pay a company to get one. If you form an LLC, file with the state first. The IRS says an EIN application can stall when the state filing is not done. A sole proprietor can often start with a Social Security number and get an EIN when a bank or a hire requires it.
Apply on the IRS page if you want the number yourself. LegalZoom, the partner beside this step, can request it while they form the company. That service is optional. The IRS fee is still zero either way.
Read the plumbing board for the exam, the hours, and who may pull a permit. Then check the city for water-heater and sewer permits. The license number belongs on the site next to the phone.
We could not confirm one statewide contractor-board address. Check the city or county, and any state board that names your specific trade.
City of St. Louis permits is the local counter for work in St. Louis. We are naming that office, not linking a fee schedule we have not read. Call them or open the city's own site and ask what a new plumber has to register before the first job in Soulard.
The Missouri guide repeats the board link and tells you what we could not verify. Read it before you pay a filing service.
05Insure the work
General liability that names plumbing, including water damage. Commercial auto for the van. Workers' compensation before a second person is in a crawl space or an attic. A water-heater job can become a claim weeks later, so ask the insurer about completed operations and keep the certificate current.
Workers' compensation is a state program. Before anyone works with you, including a friend, ask an insurer and the state labor office whether you must carry it. This guide does not quote a headcount, because those rules differ and the state page is the source. The SBA page describes the common policies. It does not sell them. Buy the policy before you work in a house in St. Louis.
Parts houses and permit fees belong on the business account. Emergency work pays in bursts. Move tax money the day the deposit clears so a slow week does not spend it. The account name should match the name on the invoice you text the customer.
The bank will usually ask for your ID, the EIN or your Social Security number, and the formation papers if you filed an LLC. A checking account and a habit of setting tax money aside are enough at the start.
07Price a day in St. Louis
Publish a service-call or diagnostic price, and quote the repair after you see it. Drains, water heaters, slab leaks, and fixtures are different visits. Say whether after-hours is a real dispatch or the next morning.
The housing decides the price more than a national rate sheet. An attic heater, a boiler, a stack in a rowhouse, and a slab leak are not one line item. Name the one you want, and refer the one you do not.

Leak repair, water heaters, and the drain or sewer work you can finish. In St. Louis, MO, list Central West End and St. Charles together only if one crew really covers both.
Write the price you want for the common job in Central West End and the price you want for a far stop in St. Charles. If the second number is not worth the drive, leave St. Charles off the service area.
08Open the profile, the reviews, and the site
Claim the Google Business Profile for St. Louis, MO. Set hours you answer. The service area should list Central West End, Soulard, and Clayton if those are real stops, and it should leave off towns you will not drive.
Ask for a review after a clean job, and ask them to mention the neighborhood and the task. A review that says the work and Kirkwood helps the next search. A review that says 'great service' does not.
Google Business Profile with the license and the neighborhoods you will drive at night. Reviews that say 'slab leak in Meyerland' are worth more than 'great guy.' The website names the failures, and the form asks what is leaking and whether water is still moving. ServiceBase files that request so you can call it back when you are out from under a house.
When the name and the phone are real, create the free plumber site with St. Louis already filled in. Quote requests land in your list. The site does not replace City of St. Louis permits.
Pick the service you can finish, search the name at the SBA: state registration lookup, get the free EIN from the IRS, read the license page, call City of St. Louis permits, insure the work, open a business account, and publish a page that names Central West End and the jobs you want. Leak repair, water heaters, and the drain or sewer work you can finish.

Can I publish a plumber site before the LLC is approved?
You can draft it. Put it in public under the name you will actually use, with the phone you answer. If the state requires the license before you advertise the work, wait. The free ServiceBase site does not file the company. Signup can open with plumber and St. Louis filled in so you are not retyping them.
