Examples
Twelve bikes vs the $218 should-cost
You assemble commuter bikes, and before the spring season you write a standard cost of $218 per bike under the conditions you expect: $165 frame kit, $28 hardware, and $25 bench labor. On April 11 you finish 12 bikes. A frame-kit supplier invoices $2,040 ($170 each), a hardware supplier invoices $360, and bench wages for that run are $360, so actual is $2,760, or $230 a bike. Enter those bills at $2,760 in QuickBooks Online or Xero; do not rewrite them to $218. The $218 stays on the cost card as the should-cost, and the $12 gap is the control signal; price variance would explain only the kit-price slice, not the whole overage.
Last January invoice is not the standard
You cook wholesale pasta sauce and never write a should-cost. On January 9, a tomato packer invoices 80 cases of crushed tomatoes at $18.50 a case ($1,480), and you treat $18.50 as the standard when you quote a grocery chain for the summer pack. On June 6 the next lot is $22.25 a case, but the jobs still look fine because you have nothing to compare except that old bill. That $18.50 was winter actual cost, not a forecast under projected summer prices and cook yield. Write the should-cost from the conditions you expect, then compare later invoices to it; price variance is the gap after that yardstick exists.
Why it matters
Standard cost is the should-cost you write before a repeatable run, under the material prices, yield, and labor you expect, and you use it for cost control and to judge productive efficiency while still posting vendor bills at actual cost. You set or refresh it when you price a SKU or start a season of the same item, and you compare after each run or at month-end if you manufacture; a reseller or a one-off custom job almost never needs one. Price variance is the price gap against that yardstick, not the yardstick itself. Treat last period's invoice as the standard and you have no forecast under projected conditions; skip the compare and you have no control signal, so leave the invoices at what you paid and watch the gap.
