This is not legal, tax, or insurance advice. Read the official pages linked here. Partner offers are optional and labeled.
Pick the calls you already know how to finish: drains and water heaters, or repipes, not all of them in week one. Write the referrals down. Gas, boilers, and sewer cameras can wait until they are honestly on the truck.
The state guides under this page cover all 50 states and the District of Columbia. Each one names the filing office and the licensing board we could verify, and it says so when we could not confirm a direct address. City guides cover the metros ServiceBase writes about for this trade, including Austin, TX, Houston, TX, Dallas–Fort Worth, TX, Las Vegas, NV.
High-demand trades with thin local websites are the ones to read first: chimney sweeps and standby generator installation in cold markets, snow removal, and Christmas light installation from November through January, then landscaping, electrical, cleaning, and roofing, in the cities linked below. The steps are the same shape for every trade. The license and the first job are not.
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. Nothing on this page is a discount code.

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.
The name should sound like a plumber a neighbor would recommend. Search the state filing office and the license board, because the name on the license and the name on the invoice have to match. Spell it the way you will answer the phone at night.
02Form an LLC or stay a sole proprietor
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.
Each state guide links the filing office. Where we could verify an LLC fee from an official page, that guide prints the fee and the source. Everywhere else, the fee stays on the state's site.
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.
Plumbing is a licensed trade in most states: an exam, documented hours, and a company registration are the usual pieces. A local permit sits on top for water heaters, repipes, and sewer work. Read the board's scope so you know whether gas, medical gas, or septic is included. Put the license number on the website. If your application is in progress, limit the work to what the board allows an unlicensed helper to do, and do not advertise the rest.
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.
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 the city you will serve.
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 the real visit
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.
08Get found, then create the free site
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.
In your first city, the profile, the reviews, and the site should name the neighborhoods you actually drive. ServiceBase publishes the page and keeps quote requests in a list on your account. No card. It does not file the LLC, get the EIN, or buy the insurance.
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. The SBA page linked in the steps explains the structures in general. A lawyer or an accountant can apply them to you. This guide cannot.
Does a plumber need a state license?
Plumbing is a licensed trade in most states: an exam, documented hours, and a company registration are the usual pieces. A local permit sits on top for water heaters, repipes, and sewer work. Read the board's scope so you know whether gas, medical gas, or septic is included. Put the license number on the website. If your application is in progress, limit the work to what the board allows an unlicensed helper to do, and do not advertise the rest.
Is an EIN free?
Yes. The IRS issues an employer identification number at no charge and says you never have to pay a fee for one. Use the IRS link in the steps if you want the number yourself. LegalZoom, the partner on that step, can request it while they form the company. That service is optional, and the IRS fee is still zero.
What does the free plumber site include?
A public page for your plumber business and city, and a list of the quote requests that come from that page. No card. It does not form the company, get the EIN, buy insurance, or replace a license. The website guide for this trade is separate: it is about what the page should say once the company is real.
