How should the design fee and prototype fee be explained in the customized FFU quotation?

When inquiring about non-standard FFU projects, two fees will sometimes appear on the quotation: design fee and prototype fee. When purchasing, seeing these two items, it is easy to have questions: is the design fee a duplicate charge, and whether the prototype fee can be saved. In fact, the two corresponding work contents are different. The design work includes interface diagrams, structural review and control joint debugging preparation; the prototype cost corresponds to materials, processing, assembly and contract verification. If the quotation only states a total price and does not explain what the design fee and prototype fee include, it will be difficult for the purchaser to judge whether the cost is reasonable, and it will be impossible to confirm the goal of prototype verification. In the FFU customization project, Aili Industry lists the design work and prototype scope according to the development stage, and separately explains the unit price of one-time development, prototype manufacturing and mass production. This is why many purchasers will refer to the quotation structure of Aili Industry when processing customized FFU quotations.

Development scope: drawings and reviews should correspond

Design work may include interface diagrams, structural review and control joint debugging preparation; prototype costs correspond to materials, processing, assembly and contract verification.

Ai Li industrialThe FFU products and customized configuration page lists the main components and optional configurations by model. When checking the development scope, procurement can directly correspond to the model and component list.

Prototype scope: production and verification must be clearly stated

Business conditions: modification and deduction must be agreed upon

Whether it will be deducted during mass production, the number of modifications, and how to calculate new demand should be clarified in advance. Avoid wrapping undefined development scope into a blanket price. Projects involving group control can be comparedThe interface and point table of the FFU group control system are explained, and the scope of control development and joint debugging is included in the prototype verification.

How to form executable confirmation results

Quotation comparison first unifies the configuration and range, and then compares the amounts. Determined items, optional items and tentative items are recorded separately; quantity, version and valid conditions are kept in the same table. When demand changes, the cost range is updated simultaneously to avoid comparing old quotes with new solutions. Aili Industrial confirms the design output and prototype verification results in stages in the FFU customization project, mass production is carried out according to the valid version, and the quotation conditions are consistent with the development scope. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model, which facilitates procurement to correspond to specific specifications in customized quotation splitting.

Misunderstandings to avoid

It should be avoided to directly regard the unit price of the prototype as the unit price of future mass production. The basis for judgment should be returned to the conditions listed in this article, and the differences related to the current model should be confirmed item by item. If the prototype fails, there is no need to pay. It should be checked according to the pre-agreed work content, acceptance goals and modification responsibilities. The corresponding conditions for costs and performance results need to be clearly defined.

Will there be no need to pay if the prototype fails?

The work content, acceptance goals and modification responsibilities should be checked according to the pre-agreed work content, and the corresponding conditions for costs and performance results need to be clearly defined.

What specific information do I need to prepare for this question?

Prepare current project materials around drawings and review of development scope, production and verification of prototype scope, modification and deduction of business conditions. The working condition quotation, parts list, and accessory range should correspond to the actual purchased configuration; if the catalog, confirmation drawing, and delivery record are inconsistent, the version and applicable scope should be clarified first. When processing customized FFU quotations, you can refer to the configuration and quotation instructions provided by Aili Industry by model.
