Illustration for Selling a Mobile Detailing Business

This guide covers what transfers, how small businesses get valued, and the IRS form that splits the price. It is not tax or legal advice, and it can’t predict your sale price.

The question owners ask

A detailer on a small-business forum described two years of work:

  • about $22,000 a month in revenue
  • 1,500 past clients
  • a lead list of 12,000 people
  • 250 five-star reviews

The owner still did about half the jobs and planned to sell the assets. What is a client list or a review profile worth, compared with the equipment?

Commenters asked about profit, not revenue, and warned of low offers for the list alone. A buyer pays for what keeps earning after you leave. If a helper does part of the work, paying your first detailing helper covers how trainee pay and raises can keep them.

Asset sale or the whole company?

The SBA says a sales agreement covers “the purchase of assets or stock of a corporation.” For a solo detailer, an asset sale is the common route. The buyer picks the pieces, and the agreement spells out who keeps any debts.

IRS Publication 544 explains why this matters at tax time. The sale of a business “is usually not a sale of one asset.” Each asset is treated as sold separately. The gain or loss on each is figured on its own.

What transfers, and how

What you’re selling IRS Form 8594 class How it moves to the buyer
Van, trailer, water tank, pressure washer, polishers Class V (vehicles and equipment) Title and bill of sale. Gear you wrote off may trigger depreciation recapture
Client list, booking history, lead list Class VI (customer-based intangibles; business records) Export and hand over the file
Business name, logo, website, domain Class VI (trade name); SBA counts websites and domains as intellectual property Written assignment; domain moved at the registrar
Google Business Profile and its reviews Not named; ask your tax preparer Add the buyer as an owner, then transfer primary ownership
Business phone number Not named; ask your tax preparer Keep service active and port the number to the buyer’s carrier
Your promise not to compete Class VI (covenant not to compete) A clause in the sales agreement
Goodwill: repeat customers, reputation Class VII (goodwill and going concern) Whatever price is left after the other classes

Reviews. The listing platform lets a profile have several owners but only one primary owner. You need at least one other owner or manager before you can hand off primary ownership. If the buyer changes the name beyond a minor tweak, its guidelines treat it as a new business. The old profile is marked closed and a new one starts from zero. Our guide to service-area Business Profiles covers the setup side.

Phone number. The FCC says you can keep a number when changing providers in the same geographic area. Its first rule: don’t cancel your service before the new company starts the port.

Lead list. A list is only as useful as the permission behind it. Our booking software guide explains the FCC’s consent rules for reminder and marketing texts.

How a small business gets valued

The SBA names three common approaches:

  • Income: looks at projected revenue and accounts for risks. If half the jobs leave with you, that is a risk.
  • Market: compares your business with similar ones that recently sold.
  • Assets: subtracts liabilities from the value of all assets. For a detailer, that’s mostly the van and gear.

The SBA’s page on buying a business says the main draw is an existing blueprint. That includes an established customer base and “fully trained employees.” A detailer who is the only trained worker has less blueprint to sell.

Regulars on maintenance plans help, and so do prices you can show on paper. That’s one more reason to keep your price list written down.

The SBA points sellers to a national valuation-standards nonprofit for appraisal resources. In Indiana, for example, the state’s Small Business Development Center says its valuation specialists offer no- or low-cost business valuations.

Splitting the price on Form 8594

The IRS instructions cover a group of assets that makes up a business changing hands. Both buyer and seller generally file Form 8594 with their tax returns. The price is spread across seven asset classes in order, using the “residual method.” What’s left lands in Class VII, goodwill.

Publication 544 says a written allocation binds both sides unless the IRS finds the amounts aren’t appropriate. Settle it with a tax professional before closing.

One trap catches detailers. If you sell depreciated equipment at a gain, the IRS says part of that gain may count as ordinary income. Keep your depreciation records for the van and big gear.

Before you list it

  • Gather financial statements and tax returns. The SBA warns that leaving any assets or liabilities out of the agreement “can create problems” after the sale.
  • Have an attorney review the sales agreement, as the SBA advises.
  • Consider a gradual sale. The SBA describes payments over time as an option for buyers who can’t pay all at once. You carry the risk if they stop paying.
  • Start early. The Indiana SBDC says a good exit strategy can take months or even years.
