How to Compare Two Multimeter Quotations Line by Line
Two quotations for the same model number rarely describe the same purchase. One may include a holster, a printed manual in the buyer’s language and a colour box, while the other prices the meter alone and treats every one of those as an extra. Comparing the two unit prices directly produces a number that looks decisive and is usually wrong, because the cheaper line is quoting a different product.
The fix is not complicated. Put both quotations into the same structure, line by line, and make each supplier state what sits under every number. A quotation that survives that treatment is comparable. One that does not is a starting point for a conversation, not a basis for a decision.
We issue quotations from a factory in Wenzhou that has been building instruments since 2008, across 127 models in four families, and the enquiries that go smoothly are the ones where the buyer arrives with this structure already in mind. The rest tend to spend a week exchanging messages about items that could have been settled in the first reply.
Start With the Same Specification, Not the Same Model Name
Before any price is compared, confirm that both quotations describe the same instrument. The count class, the DC accuracy, the range set and the accessories decide most of the cost, and a model name alone does not pin any of them down. A 1999-count meter and a 6000-count meter can carry similar family names and differ by a factor in price, and the same model sold with and without a holster is two different line items.
Write the specification you are buying into the enquiry: counts, DC volts accuracy, the ranges you need, whether temperature or capacitance is required, and the accessory list. Ask each supplier to confirm that specification in writing in the quotation. When both replies confirm the same list, the prices are finally talking about the same thing.
The Lines a Quotation Should Show
A quotation that is going to be compared needs more than a unit price and a lead time. The table below lists the lines that decide the real cost, what each one controls, and the question to send back when a line is absent. Any supplier who can answer all five in one reply has given you a document you can act on.
| Line on the quotation | What it decides | What to ask if it is missing |
|---|---|---|
| Unit price at a stated quantity | The price per piece at one specific order size, and whether it includes the accessories listed | Ask for the price at your actual quantity, not the price at the minimum |
| MOQ per model and per colour | Whether a mixed order is possible and how the price changes between tiers | Ask for the tier table, and whether models can be combined to reach a tier |
| Tooling or setup charge | The one time cost of a custom label, silk screen, housing colour or packaging print | Ask whether the charge is per order or per artwork, and what happens on a repeat order |
| Packaging, manual and label | Whether the box, the printed manual and the label are included or priced separately | Ask for the packaging specification and the language of the manual in writing |
| Trade term and port | Where the supplier’s responsibility ends and the freight cost begins | Ask for the exact term, for example FOB Wenzhou or FOB Ningbo, and for the carton dimensions |
The fifth line deserves more attention than it usually gets. A price quoted as FOB Wenzhou and a price quoted as FOB Ningbo are not the same offer, because the inland leg to the port is included in one and not the other, and the port handling charges differ. Two quotations that look five percent apart can reverse once the term is normalised to the same port.
Unit Price Means Nothing Without Its MOQ Tier
Every factory price sits on a quantity curve, and a quotation that gives one number without saying which point on the curve it belongs to cannot be compared with anything. Ask for the tier table: the price at your trial quantity, at the quantity you expect for the first year, and at the quantity that fills a container. The shape of that table tells you more about the supplier than the first number does.
Ask as well whether models can be combined to reach a tier, and whether colours count separately. A supplier who requires the full minimum for each model and each colour is offering a different commercial proposition from one who will combine a mixed order, even when the headline unit price is identical. This is the point where a factory price and a retail or trading price separate most clearly, and it is worth settling before samples are discussed.
Tooling, Samples and Who Pays for Them
Custom work carries a one time cost, and the quotation should say what it covers and when it is charged again. A label or a printed box usually involves artwork, a plate or a print run, and the supplier may charge once per artwork or once per order. Ask which, and ask what happens when the same artwork is repeated next year.
Samples are the other line that gets buried. Ask whether the sample is charged at the unit price or at a handling price, whether the courier cost is on your account, and whether the sample charge is credited against the first bulk order. Our own terms are that sample cost is refunded from the first bulk order of the same model, and samples ship by express in three to seven working days, but the point of the question is not our answer. It is that every supplier should have one, and the ones who do not are telling you something about how the order will be handled later.
Packaging, Manuals and Labels Are Priced Separately
Packaging is where two quotations diverge most often, because it is easy to quote a meter and silent about the box. A colour box, a printed manual in the destination language, a barcode label and a shrink wrap are four separate items, and a supplier may include some and charge for others. Ask for the packaging specification in writing, including the carton quantity and the carton dimensions, because those numbers decide the freight.
Language is the part that gets missed. A manual printed in English is not the same line item as a manual printed in Spanish, Russian or Arabic, and the second one may need artwork, a proof and a minimum print run. If your market needs a localised manual, put it in the enquiry rather than discovering it at the packing stage. Our own note on packaging and manual localisation sets out what that work involves and where the lead time goes.
Trade Terms, Payment Split and the Real Delivered Cost
Once the unit price, the tier and the packaging are aligned, three more lines decide the cash cost of the order. The trade term fixes where the supplier’s obligation ends. The payment split fixes how much money leaves your account before the goods leave the factory, and the warranty fixes what happens after they arrive.
Our standard terms are FOB Wenzhou or FOB Ningbo, T/T with a 30 percent deposit to confirm production and the balance before shipment, and L/C at sight for larger amounts. A 12 month warranty covers defects in the instrument. Those are our terms, not a universal benchmark, and a quotation from another supplier may offer something different on every one of the three lines. The comparison only works when both quotations state them, so ask for all three explicitly and write the answers into the same table.
The payment split matters more than it looks on a small order. A supplier asking for the full amount before production and one asking for thirty percent are offering different risk positions even at the same unit price, and the difference belongs in the comparison rather than in a footnote. The same applies to the lead time: ask whether it is counted from the deposit, from artwork approval or from the sample sign off, because those three starting points can be a week apart.
What to Send Back to Make the Comparison Conclusive
With both quotations normalised, the reply that settles the decision contains four things: the specification both suppliers confirmed, the tier table at your real quantities, the packaging and manual specification, and the trade and payment terms. Send that package to each supplier and ask them to restate their price against it. The prices that come back are comparable, and the supplier who answers precisely is usually the one who will handle the production order precisely as well.
If you are at that stage now, send us the specification and the quantities you are working with. Engineers and sales staff at our factory in Wenzhou will return a quotation in that structure, with the tier table, the packaging lines and the trade terms spelled out, so it can be put next to the other reply without a translation step. That reply normally goes out within one working day, and it will name the models in the range that fit the specification you sent rather than the models we would prefer to sell.
For an order that involves a private label or a custom range, the OEM and private label overview explains what the factory needs from you before artwork can start, and the sample to production timeline sets out the stages between a confirmed sample and a shipped carton. Reading both before the quotation stage usually removes one round of questions from the exchange.
