In short
Applies to: Business owners, anyone learning accounting, and finance teams
- An order-level setup cost is spread across fewer units in a small batch, so its cost per unit can be higher.
- Prepare the quotation using the actual quantity and scope. Keep short-term additional-cash decisions separate from sustainable pricing that must cover the business over time.
A customer asks for ten units at the same unit price as an order of 100. Material use may scale with quantity, but machine setup, design, inspection preparation and delivery may not. Ignoring those costs can turn a seemingly reasonable quotation into a loss-making order.
Separate the unit and order costs
Define exactly what the customer is buying: quantity, specification, tolerances, packing, inspection, delivery and credit terms. Identify the costs that arise for each unit and those that arise once for the order. A supplier quote that omits special testing or freight is not directly comparable with one that includes them.
A fictional batch comparison
Assume material and variable processing cost ₹400 per good unit. Each order also causes ₹6,000 of setup and ₹1,000 of order-specific packing/delivery. These order costs are assumed incremental for each separate batch and have not been included in ₹400.
| Included cost | 10-unit order | 100-unit order |
|---|---|---|
| Unit-related cost at ₹400 each | ₹4,000 | ₹40,000 |
| Setup | ₹6,000 | ₹6,000 |
| Order packing/delivery | ₹1,000 | ₹1,000 |
| Total included order cost | ₹11,000 | ₹47,000 |
| Included cost per good unit | ₹1,100 | ₹470 |
A ₹650 unit quote earns ₹6,500 on ten units against ₹11,000 of listed costs: a ₹4,500 shortfall before other costs. On 100 units it earns ₹65,000 against ₹47,000, leaving ₹18,000 before other costs. This is not an automatic reason to accept or reject either order; it shows why the batch assumptions matter.
Markup is still different from margin
If the ten-unit order needs a 25% markup on the listed ₹11,000, the quoted amount is ₹13,750, or ₹1,375 per unit before GST. The ₹2,750 difference is 20% of ₹13,750. It is not necessarily net profit: general fixed costs, finance, tax and excluded risks still need consideration. See the Price-Setting Calculator for the denominator distinction.
Consider the commercial alternatives
- Show an order setup charge separately when commercially appropriate.
- Set a minimum order value supported by your cost working.
- Offer a different unit rate for a genuinely larger batch.
- Combine compatible production runs only when quality, timing and specifications allow it.
- Confirm charges for design changes, retesting or expedited delivery before accepting the scope.
Check capacity and the time horizon
A special order using otherwise idle capacity needs a review of additional cash flows and any benefit forgone elsewhere. Existing fixed-cost allocation is not automatically an incremental cost. But regularly quoting only additional cash cost can leave the wider business unable to cover rent, people and equipment. Short-term acceptance analysis and a sustainable pricing policy answer different questions.
If the job displaces a better order, include the contribution lost from the displaced work in the decision. Also check whether a low introductory quote creates future expectations or conflicts with existing commitments. The simple table assumes available capacity, no displacement and no additional quality or collection risk.
Questions that often come up
Is every setup cost fixed forever? No. In this example it is fixed for one batch but repeats with each separate order. Cost behaviour depends on the activity being considered.
Can the customer’s larger quantity always reduce cost per unit? Not necessarily. Larger orders can create overtime, extra tooling, storage or working-capital needs.
Does this determine a legally prescribed price? No. It is a management quotation example with stated assumptions, not a statutory valuation.
Your next practical step
Take one recent small order. Rebuild its working using good output, setup, testing, rework, delivery and credit terms. Compare the accepted price with the cost and risks actually assumed. Explore CAS-10: Direct Expenses for traceable job charges.
