Examples
Eighteen chairs vs the $94 preset
You build outdoor furniture. Before the season you write a cost standard of $94 per cedar Adirondack chair (lumber, hardware, and shop labor). In May you finish 18 chairs. A lumber supplier bills $1,260 for boards, a hardware supplier bills $216 for bolts, and shop wages for that run are $540, so actual cost is $2,016, or $112 a chair. The $18 unfavorable variance is the point of the standard: you still enter the lumber and hardware bills at those amounts, then compare $112 to $94 on a production sheet. Do not change the vendor bills to $94. Watch the gap; if lumber keeps running over, refresh the standard or raise the selling price.
Leftover soap is not stocked at the preset
You make bar soap. You set a cost standard of $3.20 per bar for the lavender SKU. In September you pour 400 bars. An oils supplier bills $1,040 for oils and you record $480 of kettle wages, so actual is $3.80 a bar. At September 30 you have 90 bars left. In QuickBooks Online or Xero you change the inventory item cost to $3.20 so leftover stock matches the preset, and the extra $0.60 a bar sits in supplies expense. That hides the variance and understates inventory by $54. Leave the 90 bars at the $3.80 actual (or keep a variance account). The $3.20 is the yardstick you compare against, not the stock value. A cost sheet would only list those actual oils and wages after the pour; it is not the preset.
Why it matters
A cost standard is a dollar target you write before you make a repeatable product, then you compare what you actually spent. You set or refresh it when you price a SKU or start a season of the same item, and you check it after each run or at month-end if you manufacture; a reseller or a one-off custom job almost never needs one. The cost sheet adds up actual elements after the fact. A cost unit is only the quantity you measure against, such as each or a pound. Cost-plus is a customer pricing method, not an internal yardstick. If you post inventory at the preset and dump the difference into expense, stock and cost of sales are wrong, and you cannot see whether materials or labor ran over.
