A quote you can act on comes from one complete first message

Start with the purchasing type: a complete standard assembly, full bar stock, cut-to-length parts, end machining, replacement of an old part, or distributor stock. Each route follows a different quoting path. Standard parts are checked against model, nut fit and stock; bar stock is priced on material and cutting; machined parts are priced from the drawing and the operations it needs. Leave the type out and the supplier can only quote the broadest case, or send a question back. That spends the first round on nothing.

Then close each line item. One row per model should carry diameter and lead, overall length, thread length, nut style and nut quantity, quantity, the accuracy requirement or the machine it goes on, packing, destination and target date. A mixed order cannot be reduced to a single total quantity, because a total hides the batch structure and forces a cautious estimate. Fields you genuinely do not know yet can be marked as pending, as long as you say who will decide them and when. That is far more useful than an empty field.

Validity, payment terms and changes all need settling before payment

A quotation is tied to the material price, exchange rate, stock position and production slot at the time it was written. Validity is therefore a working condition, not a formality. Payment terms carry the same weight: the deposit share, the balance trigger, who absorbs bank charges, and the exact point the delivery period starts. State whether it starts when the deposit lands, when the drawing is approved, or only when both are done. One extra line at quotation stage saves a round of emails on payment day and keeps the production slot stable.

Drawing changes and quantity changes both need re-confirmation, and one question decides whether a full re-quote is required: does the change alter how the part is machined or how it is inspected? If it does, ask for a new quotation and state whether the earlier one is withdrawn. If it does not, a written note on the existing quotation is enough. Quantity moves more than unit price: more models in the mix changes batch planning, more long parts changes the packing and freight structure. Send the old drawing, the revised drawing, the version number, the change list and the new quantity list in one message, so cost, timing and re-sampling can be judged together.

Before requesting a custom ball screw quote, list the drawing, dimensions, accuracy, quantity, and packing requirements.

Align these before you send

Put the items below into the same message. In most cases the reply is a price you can execute on, rather than a request for missing information.

  • Purchasing type: standard assembly, bar stock, cut length, end machining, replacement, or distributor stock.
  • One row per model: diameter and lead, overall length, thread length, nut style and nut quantity.
  • Machining scope: support unit model, end drawing, bearing journal and coupling-end fit.
  • Packing: rust prevention, labels, carton marks, long-part support, and whether shipment photos are needed.
  • Commercial frame: target date, destination, quotation validity, and who confirms the payment terms.
  • Change record: drawing version, change date, and whether the earlier quotation still applies.
  • Application note: machine type, travel, speed and mounting direction, so the selection can be checked.

FAQ

RFQ and quotation questions

These three come up at quotation stage more than any others, and each one decides how many emails follow.

Can I get a quotation with only a model number?

Yes, but the quotation will carry conditions. Without diameter and lead, length, nut style and quantity, the supplier can only price a general configuration, and any later difference has to be reconfirmed. Marking the unknowns is more useful than leaving them out.

The quotation is still within validity. Can I pay against it?

Check the scope it covers first: models, quantity, accuracy, machining, packing, destination, and when the delivery period starts. If nothing changed, the quotation can be used as issued. If any single item moved, ask for an updated quotation instead of releasing production on the old scope.

Why does a quantity change need a new price?

Quantity changes more than the unit price. Batch planning for mixed models, packing for long parts and the freight structure all follow it. Send the new quantity list with the models grouped, and reconfirm once rather than correcting it during production.
