# 下单前检查清单：买钢材、木材或瓷砖之前

下单前十分钟的核对，省掉再跑一趟供应商。

## 1\. 先优化，再清点

不要凭原始工件清单直接下单。把清单跑一遍优化器，看方案实际需要多少根型材、多少张板材或多少箱，再按这个数字下单。与手工估算相比，材料需求可以下降 10–15%。

## 2\. 加一个受控的余量

为返切和搬运损伤加 5–10%——不要更多。过大的余量会掩盖计划错误并占用现金。把余量写进订单，但让它作为单独一行保持可见，这样才能追踪实际用了多少。

## 3\. 查清你已有的库存

边角料架、上个任务剩下的箱、用剩的短料——把它们作为原料填进计算器，让新材料只补足差额。线性计算器正是为这种场景支持多种原料长度。

## 4\. 确认尺寸与标准

型材是 6 m 还是 6.1 m？板材是 2440×1220 还是 2500×1250？钢筋用美制还是公制？板规还是 mm？每个行业都有地区标准——在定稿方案之前，与供应商确认实际到货尺寸。

## 5\. 合批，并对好批次

把本周的任务合并成一张订单，价格更好、送货更少。瓷砖和壁纸要确认所有箱子同一批次或同一批号——不同生产批次颜色会有差异，铺上之后一目了然。
