What should I do if items are missing from a whole-house customization quote? How should I check the quotation?

Check the quotation in three steps: ① Check the spaces — confirm whether each space (entryway, living room, dining room, kitchen, bedroom) has corresponding cabinet body line items, to avoid under-reporting followed by later add-ons; ② Check the specifications — confirm whether the cabinet body particle board, door panel, edge banding process, hardware brand and model, and worktop material are each stated item by item; ③ Check the costs — confirm whether transport, carrying upstairs, installation, removal of existing cabinets, cutouts, visible end panel, and closing strips are listed separately and whether they are included. If you find missing items, ask the other party to add them into the same quotation before comparing prices. Note that the reference unit price is only a budget reference and does not equal a formal quote; the final calculation is based on dimensions, specifications, and on-site conditions.
