Lesson 4: Inspection and Negotiation

You have found equipment you want. Everything from here is about reducing the number of ways this can go wrong. That happens in two stages: an inspection that tells you what you are actually buying, and a negotiation that assigns every cost and every risk to somebody in writing.

New buyers spend almost all their energy on the first number and almost none on the terms. That is backwards. The difference between $3,000 and $2,700 for a chair is $300. The difference between "buyer handles removal" and "seller delivers to your dock, disconnected by a licensed technician" can be several times that, and it is far easier to win because it costs the seller convenience rather than cash.

Decide who inspects before you schedule anything

Three levels of inspection exist, and choosing the wrong one is expensive in both directions.

The rule of thumb: if a plausible hidden problem would cost more to fix than ten inspections, hire the technician. On a full operatory package the technician is not an expense, it is the cheapest insurance available. Our overview of what to expect from a dental equipment inspection covers what a professional actually does during a visit.

The inspection sequence

Work in the same order every time. Consistency is what stops you from forgetting the serial plate on the one purchase where it mattered.

Step 1: Identity and paperwork, before you touch anything

1. Photograph the serial plate on every item, and the model number.
2. Confirm the serial matches any paperwork the seller has provided.
3. Ask for service records, manuals, and the original invoice. Photograph them.
4. For anything with software, record the software name and version and ask about license transfer.
5. Ask directly whether there is a lien, lease, or outstanding financing on the equipment.

Step 2: Watch it run, cold

Do not let the seller warm everything up before you arrive. Equipment that has been running for an hour hides the problems that show up on a cold start. Ask for it to be off when you get there, then power it up yourself.

Step 3: Cycle everything, repeatedly

Single tests prove nothing. Run the chair through its full range of motion many times, use every preset, and watch whether it holds position. Run a sterilizer through a complete cycle, not a power-on. Let the compressor cycle and check how long it runs and how often. Intermittent faults are the ones sellers honestly do not know about.

Step 4: Category checks

The pre-purchase checklist and the printable inspection checklist cover this in detail. The short version for the items a startup buys most:

Step 5: Photograph everything, including the problems

Photograph each item from all sides, each serial plate, each defect you found, and the room it sits in. This becomes your record of condition at the time of sale, which matters if the equipment arrives different from how you saw it.

Turning findings into a number

Do not negotiate on impression. Negotiate on a list. After the inspection, build a two-column sheet: what needs to be done, and what it costs.

Hypothetical example. A chair and delivery unit are listed at $4,500. Your inspection finds worn upholstery, original tubing, and slow lift on the chair. Your technician quotes the work.

Now compare that all-in number to a refurbished unit from a dealer with a warranty, and to new. If the dealer's refurbished package is $7,800 installed with a six-month warranty, the "cheaper" private chair is not cheaper. That is the argument you bring to the seller, and it is a much stronger one than "would you take $4,000?" Sellers respond to a specific list of costs far better than to a lower number with no reasoning behind it.

Two rules for using this sheet:

• Share the list, not the conclusion. "Here is what my technician says this needs" is information. "Your chair is junk" ends the conversation.
• Never count the same problem twice. If you are already planning to reupholster because you want a different color, that is not a defect to deduct.

The seven terms that matter more than price

Negotiate these before you negotiate the number, because each one is worth money and most sellers have not thought about them.

1. Inspection contingency. Your offer is subject to a satisfactory technician inspection. If a seller refuses this, that is your answer about the equipment.
2. Who disconnects, and who pays. Disconnection of chairs, delivery units, compressors, and vacuum involves water, air, drains, and electrical. Get it in writing who does it and to what standard, including capping and making the seller's space safe. Read how to disconnect dental equipment safely before agreeing to do it yourself.
3. Who crates, loads, and ships, and on whose account. Freight is a large line on heavy equipment, and whoever books it controls the liftgate, the class, and the insurance. See shipping dental equipment.
4. When risk of loss passes. At pickup, at delivery, or at install. This decides who eats freight damage. Say it explicitly.
5. Arrival condition guarantee. Even on as-is equipment, ask for a short written guarantee that items will power up and function as demonstrated when they arrive, with a stated remedy. Sellers who saw it working will often agree, because they believe it.
6. Removal date and access. Who has keys, what hours, whether a freight elevator is needed, and what happens if the seller's schedule slips past your install date.
7. What is included. Foot controls, headrests, armrests, handpiece tubing, trays, manuals, software media, spare parts, tools. List them. Missing accessories are the most common post-sale argument in this market.

The bill of sale

Even a modest private purchase deserves one page. At minimum it should state:

• Seller and buyer legal names, addresses, and contact information
• Every item by make, model, and serial number, with quantities and accessories listed
• Price, deposit, payment method, and payment timing
• Condition terms: as-is, or as-demonstrated, plus any arrival guarantee or holdback
• Who disconnects, crates, loads, and ships, and who pays for each
• Removal date and the point at which risk of loss passes
• A seller statement that they own the equipment free of liens, leases, and security interests
• For x-ray equipment, an acknowledgment of who will file the state notification of transfer
• For anything that held patient data, confirmation that drives were wiped or removed
• Signatures and date

As-is is not the enemy. Most used equipment sells as-is and that is normal. As-is combined with as demonstrated on a stated date, a serial-number list, and an arrival guarantee is a reasonable deal. As-is with no item list, no serials, and no delivery terms is not a deal, it is a hope. Contracts and liens are areas where a dental-specific attorney is worth a short consult, especially on a package purchase from a closing practice.

Making the offer

1. Open with the package, not the price. "I can take all three operatories and the compressor, pay a deposit this week, and have it removed by the fifteenth" is a strong opening because it solves the seller's actual problem.
2. Anchor with your cost list. Present the repair and logistics sheet and make an offer that reflects it.
3. Ask for terms you value before price. Trade price for terms deliberately: you can pay closer to asking if the seller handles disconnection, or less if you do.
4. Put a date on the offer. Offers without expiration invite shopping.
5. Deposit carefully. A deposit is normal on a package deal. Keep it proportionate, put its purpose and refund conditions in writing, and pay it by a method with a record and recourse. Lesson 4 of the reselling course covers payment safety in detail from the other side, and the same rules protect you as a buyer.

When to walk away

Walking away is a skill, not a failure. In a market where equipment turns over constantly, there is another chair. There is not another opening day.

What to do before Lesson 5

Once terms are agreed, the purchase becomes a logistics problem with a deadline attached to it. Lesson 5 covers the handoff: scheduling removal and freight, sequencing installation against your buildout, commissioning equipment, and the week before you see your first patient. Before then, write your bill of sale template so you are not drafting one at the moment a seller says yes.

Try it

1. Build your inspection kit and sequence. Write a one-page inspection form for the categories you are buying, in the five-step order above. Print several copies. Using the same form every time is what makes the tenth inspection better than the first.
2. Get a technician quote. Call an independent service company and ask what they charge for a pre-purchase inspection of a chair and delivery unit, and whether they travel. Compare that number to the cost of a hydraulic service. That ratio is your argument for hiring them.
3. Practice the cost sheet. Take any current listing for a chair and delivery unit and build the all-in table from this lesson using estimates from the linked guides. Compare the result to a dealer refurbished package. Decide which you would actually buy and write down why.
4. Draft the bill of sale. Write the one-page template now, with blanks. Include the seven terms. Have a dental-specific attorney look at it once; you will use it for years.
5. Rehearse the ask. Write the exact sentences you will use to request an inspection contingency, an arrival guarantee, and a holdback. Read them aloud. These are easier to ask for when you are not inventing the wording in the moment.

Check yourself

1. Why should equipment be cold when you arrive to inspect it?

Because warmed-up equipment hides cold-start problems. Hydraulics, compressors, and electronics often behave differently on first power-up, and those are exactly the faults a seller may honestly not know about. Ask for everything to be off and start it yourself.

2. What is the strongest way to justify a lower offer?

A specific, itemized list of what the equipment needs, with technician estimates, plus the logistics costs you will carry. Sellers respond to a list of costs far better than to a lower number with no reasoning attached.

3. What does a holdback do, and why do sellers often accept one?

It splits payment so that a portion is released only after the equipment arrives and functions as demonstrated. Sellers who genuinely know their equipment works accept it easily, because it costs them nothing. A refusal is information.

4. Why does risk of loss need to be stated in writing?

Because it decides who absorbs freight damage. If the bill of sale does not say whether risk passes at pickup, at delivery, or at installation, a damaged chair becomes an argument at the worst possible time. State it explicitly and align it with who booked and insured the freight.

5. Is as-is a reason to walk away?

No. Most used dental equipment sells as-is and that is normal. What matters is whether as-is is paired with a serial-number item list, a record of what you saw working on a stated date, clear delivery terms, and ideally a short arrival guarantee. As-is with none of those is not a deal worth doing.
