Pennsylvania
Do you need a license to be a mobile mechanic in Pennsylvania?
We did not find one, and the Department of State catalogue of licensing boards is why. The rules that do reach you are a consumer protection regulation and a tax registration.
Pennsylvania does not appear to license automotive repair. The evidence is the Department of State catalogue: the Bureau of Professional and Occupational Affairs supports 29 licensing boards and commissions, and the list runs from Accountancy to Veterinary Medicine with exactly one vehicle entry on it, for manufacturers, dealers and salespersons. Repair is not there.
That is a weaker kind of negative than the one Texas offers, and the difference is worth naming. Texas has an agency that writes down in print that the state does not license repair shops. Pennsylvania has an agency that lists what it does license and does not list repair. The first is a statement, the second is an absence, and an absence from one catalogue is not proof that nothing exists anywhere in Pennsylvania law.
Two things do reach a mobile mechanic here, and both are more useful than the license question. The Bureau of Consumer Protection has a regulation on automotive industry trade practices whose definition of a repair shop is a person doing the work rather than a building it happens in. And the sales tax rules treat repair to a motor vehicle as a taxable service, so the labor is taxed here, and they say where the tax license lives when the business has no regular premises.
Twenty nine licensing boards, and repair is on none of them
The Department of State page for boards and commissions states how many there are and then lists them. Reading the list is the fastest way to see the shape of Pennsylvania occupational licensing: it covers medicine, the trades that touch the body, the professions with a public safety exam behind them, and vehicle sales.
The only vehicle related board is for manufacturers, dealers and salespersons. Somebody who sells you a car in Pennsylvania is licensed by a board. Somebody who repairs it is not on that page.
We are reporting what the catalogue contains. Pennsylvania statutes are large and this page has not read all of them, which is why the search list below shows the pages we actually opened rather than claiming the question is closed.

The regulation defines a repair shop as a person, not a building
Chapter 301 of Title 37 is the Bureau of Consumer Protection regulation on automotive industry trade practices, and its definitions section is where the mobile question is quietly settled. A repair shop is a person who diagnoses or repairs vehicles for compensation. There is no premises in the sentence.
The definition then names examples, and they are all buildings: body shops, retail stores offering automotive services, dealer service departments. Reading only the examples would give the wrong impression, because they are introduced as things the definition includes rather than as its limits.
The one carve out in the definition is the fleet case. An establishment that repairs and maintains vehicles for the exclusive use of its own employees sits outside it. That turns on whose vehicles are being worked on, not on where.
“A person who, for compensation, engages in the business of diagnosing or repairing malfunctions of or damage to motor vehicles”

Pennsylvania taxes the work on a vehicle, by name
The sales tax regulation on persons rendering taxable services lists what counts, and motor vehicles get their own line rather than being folded in with tangible personal property generally. Inspecting, cleaning, lubricating, polishing, repairing and waxing a motor vehicle are all named.
The heading of the subsection is the part people miss. These are taxable services whether or not any tangible personal property changes hands, so a diagnosis with no parts fitted is not obviously outside the tax in Pennsylvania the way it would be in Texas.
The same regulation puts the consumables on the business. A repair shop pays tax on the brushes, sandpaper and masking tape it uses up, and may buy the parts that go to the customer under a resale exemption instead. That split is the same one every state draws, and Pennsylvania draws it with an auto repair shop as its worked example.

The one regulation in this cluster written for somebody without premises
Registration for sales tax purposes is required of a person who maintains a place of business in the Commonwealth and sells taxable services here, and the Department issues a license rather than charging for one. The registration itself is free.
What makes this section unusual is the display rule. The regulation says where the license hangs, and then anticipates the case where there is nowhere to hang it: if the licensee has no regular place of business, it goes on the cart, stand, truck or other merchandising device, and if there is no such device the licensee carries it.
That sentence was written decades before anybody used the phrase mobile mechanic, and it is still the clearest acknowledgement in this whole cluster that a taxable business can be a person and a vehicle. It is worth reading before assuming that Pennsylvania rules assume a building.

- City and township business privilege taxes and licenses, which vary across Pennsylvania and are not a state matter.
- The full list of unfair practices in section 301.5, which is longer than the parts quoted here and includes storage, parts return and completion time rules.
- The statutory exemptions from sales tax that a particular customer may hold, such as those available to manufacturers and farms.
Questions people ask
Is there a Pennsylvania state license for auto repair?
We did not find one. The Department of State supports 29 professional and occupational licensing boards and the published list contains no automotive repair board. That is an absence from a catalogue rather than an agency saying no license exists, and it is weaker evidence than the equivalent statement Texas publishes.
Is repair labor taxable in Pennsylvania?
The Department of Revenue regulation on taxable services names inspecting, altering, cleaning, lubricating, polishing, repairing and waxing motor vehicles, and applies whether or not tangible personal property is transferred with the service. Read the regulation before pricing a job on the assumption that labor is free of tax.
Where does a mobile business display a Pennsylvania sales tax license?
The regulation says that where the licensee maintains no regular place of business the license goes upon his cart, stand, truck or other merchandising device, and that a licensee with no such device carries it.
Does Pennsylvania require a written estimate?
The trade practices regulation treats charging for repairs that were not authorized in writing as an unfair or deceptive practice, and then sets out three alternatives a customer may choose from when the repairs and their cost are not known at the outset. The choice between them belongs to the customer.
Who checked this, and what it is not
This page has not been reviewed by a licensed professional. It was written by reading the agency pages quoted above and nothing else. Every quote links to the page it came from and carries the date we read it, so you can check each one yourself, and the agency is the only thing on this page that is authoritative.
This is not legal, tax or accounting advice, and it does not tell you what you have to do. It describes what the agencies publish, on the date we read it. Rules change, and a rule can apply differently to two businesses that look alike. Check with the agency, or with a lawyer or accountant licensed in your state, before you act on anything here.

Where a CRM fits into any of this
Most of what is quoted above is a records problem wearing a legal hat: a written estimate the customer agreed to, an invoice that splits parts from labor, and a way to find both a year later. Fixty is a CRM for one mobile mechanic that does those three things from a phone, alongside photo inspections, scheduling and card payments. Starter is $99/mo with a 14 day free trial. It does not tell you what your state requires, and nothing here is advice about that.
