- Compare specifications, not totals: make both suppliers quote the same configuration before you compare prices.
- Peak power, total stack power and average output are three different numbers that all get printed as the same watt figure.
- Price the omissions: spare parts validity, training, packing grade and warranty freight often outweigh the quoted discount.
- The beneficiary name on the bank account must match the invoice and the business licence, or the deal is not safe to fund.
A quotation from a Chinese laser factory is not a price. It is a specification document with a number at the bottom, and the number is the least informative part of it. Buyers lose more money on the lines they never read than on the price they negotiate.
We write quotations every day and we read our customers' competing quotations every week. This is a buyer's guide to reading one — including the parts that are technically not lies.
Why two quotes for the "same" machine differ by 300%
"Diode laser, 808 nm, 1200 W" describes dozens of different products. Two factories can both be accurate and still ship machines that behave nothing alike, because a model name is not a specification. Here is what actually changes between a stripped-down unit and a fully configured one:
- Laser source count and brand. A 4-bar stack and a 12-bar stack can share a model name and have completely different treatment speed, lifetime and repair cost.
- How power is defined. Total stack power, peak handpiece power and average output are three different numbers that all get printed as "1200 W".
- Spot size options. One fixed large tip, or a set that lets you treat large areas and small areas at the correct energy density.
- Cooling architecture. TEC plus water plus compressor is not the same as a radiator-only loop, especially in a 35 °C treatment room.
- Software and screen. A large interface with saved protocols and a locked-down panel both "have a touchscreen".
- Spare part grade. Handpieces and power supplies from the same bill of materials as the demo unit, or whatever was available that week.
None of this appears on a one-page quotation unless you ask for it. So step one is not negotiating. Step one is making sure both quotes describe the same machine.
The eight lines that carry the real price
| Line on the quotation | What it usually says | What it can hide | Ask for in writing |
|---|---|---|---|
| Power | "1200 W" | Peak vs average, and where it is measured | Fluence in J/cm² at a stated spot size and pulse width |
| Wavelength | "808 nm" or a four-wavelength list | One stack vs several independently switchable stacks | Which wavelengths are standard and which are paid options |
| Spot size | One number, e.g. 12×18 mm | Which sizes exist later, and the price per extra tip | Full size list, including the small tip used on faces |
| Laser source | "Imported bars" | Brand, and rated shot count | Brand and rated shot life, stated on the invoice |
| Cooling | "Water + air + TEC" | Whether a compressor is actually fitted | Maximum ambient room temperature the unit is rated for |
| Handpiece | "Standard handpiece" | Whether a spare is available, and at what price | Spare handpiece price today, valid 12–24 months |
| Warranty | "2 years" | What is excluded, and who pays return freight | Exclusions list, response time, freight responsibility |
| Certificates | "CE / ISO available" | Whether the certificate names your exact model | The document with the model number visible |
Most of these answer "it depends", and that is fine. What matters is whether the supplier can answer all eight in writing in one reply. A supplier who deflects three of them has told you something useful.
Peak power vs average power: the number that gets inflated
Power is the most abused figure in this industry because it is easy to inflate and hard for a buyer to measure. Peak power is a momentary value measured in microseconds. What reaches the skin across a pulse is energy density: joules per square centimetre, delivered through a particular spot size over a particular pulse duration.
Three questions cut through it:
- "At which point is the 1200 W measured — total stack, handpiece output, or peak?"
- "What is the maximum fluence in J/cm² through the largest spot size?"
- "Will you show the power meter reading at the handpiece output in the pre-shipment video?"
A factory that tests every unit on a meter before shipping will not hesitate on the third question. This is why our own diode laser platforms and picosecond systems are quoted with energy and spot-size tables rather than a single watt figure: a number without a measurement point is marketing, not a specification.
What the quotation quietly leaves out
These gaps are rarely malicious. They are simply the items a factory omits when the last buyer did not ask. Price them in before you compare totals.
- Spare parts list and prices. Ask for 12–24 months of price validity. A machine you cannot repair economically is a write-off with a warranty attached.
- Training. Live session, protocol library, operator manual in your language. "Free training" often means a PDF.
- Packing grade. Export crate versus cardboard. Sea freight in a thin crate is how handpieces arrive bent.
- Freight, insurance and duty. None of these is inside a FOB number.
- Battery transport documents if the unit contains lithium cells: MSDS plus UN38.3 test summary.
- Consumables. CO2 tips, needles, gel, membranes. CO2 fractional platforms in particular carry a real recurring consumable line.
- Software. Whether protocols are editable, and whether the unit counts treatments or locks itself.
- Local compliance. Who is responsible for electrical requirements and registration in your market. That is a question for your authority or a local consultant, not for the factory.
Entry quote vs configured quote: where the difference goes
The table below is illustrative — the point is the direction of each line, not an amount. It compares the same machine bought two ways.
| Item | Entry quote | Configured quote | Three-year consequence |
|---|---|---|---|
| Laser stack | Fewer bars, shorter rated life | More bars, brand named on the invoice | Earlier replacement, or lost treatment days |
| Spot sizes | One large tip | Large plus small tip | Cannot treat small areas safely; referral cases go elsewhere |
| Cooling | Radiator loop only | TEC + water + compressor | More downtime in summer, more patient complaints |
| Spare handpiece | Not offered, price unknown | Priced at order, one held in stock | Two to six weeks idle instead of one day |
| Warranty freight | Buyer pays both ways | Split, with a stated response time | One repair can consume a large share of the saving |
| Training | Manual only | Live session plus protocols | Under-treated patients and weaker word of mouth |
The honest comparison adds three years of ownership to both columns: consumables, one probable repair, spare parts, and the revenue lost during downtime. The entry quote rarely wins that comparison, which is why the cheapest quotation usually turns out to be the most expensive one.
The five-minute quotation audit
- Is the currency stated, and is the Incoterm (EXW, FOB, CIF, DDP) written next to the total?
- Is there a price validity date, and does it match the lead time?
- Is power defined at a named measurement point, with units?
- Are the included wavelengths and spot sizes listed individually?
- Does the certificate carry the same model number as the quotation?
- Are warranty exclusions written out, including freight responsibility?
- Are spare parts prices attached, with a validity period?
- Is the payment structure stated: deposit percentage, balance trigger, beneficiary name?
Eight yes/no answers. A quotation that fails four of them is not a quotation, it is a price list.
Payment terms: the part people read last and should read first
A normal structure is a deposit to start production and the balance before shipment, or against a pre-shipment video of your own serial number. The percentages matter less than where the money goes.
- The beneficiary name must match the company on the invoice and on the business licence. A different name appearing at the payment step is the most common fraud signal in this trade.
- Pay to a company account, quoting the proforma invoice number. Not a personal account, not a third party's collection account.
- Tie the balance to something you can verify: a named inspection, a test video showing your serial number, or a bill of lading.
- On larger orders, a letter of credit is a standard tool rather than paranoia. Ask your bank for the cost before deciding it is not worth it.

Ten questions to send back in writing
- Which exact model and configuration does this price cover?
- At which point is the stated power measured, and what fluence range is guaranteed?
- Brand and rated shot count of the laser source, stated on the invoice?
- Which certificate covers this model number, and can you send it with the model visible?
- What is excluded from the warranty, and who pays freight in each direction?
- Can you send a spare parts price list valid for 24 months?
- What is in the export packing, and is it rated for sea freight?
- What maximum ambient temperature is the cooling system rated for?
- What training is included, in what format and language?
- Which documents ship with the unit: manual, test report, battery documents, packing list?
Ten questions, one email. Answers that come back quickly, in writing, with numbers, mean you have found a supplier worth the next conversation.
Bottom line
A quotation is a draft contract, not a price tag. Read the eight lines that carry the real cost, force every ambiguous number into writing, and add three years of ownership before you compare totals. If you do only one thing after reading this, run the five-minute audit on the quote sitting in your inbox right now.
If you want a second pair of eyes on a quotation — ours or a competitor's — send it to our engineers. We will mark what is properly specified, what is missing and what it would take to fix it, with no obligation. You can also email it to gaojiping@xhlmarketing.com.
