For a 12 × 8-inch steel cover, the catalog's minimum-or-piece model gives a coating invoice of $224.00 for one part, $22.40 each at ten and $3.78 each at 100. If your finisher instead adds $200 per lot to the per-part price, the second table shows that different contract. Confirm which rule applies before sending your quote.

The catalog treats $200 as a minimum
This is an outside-service example for fabricated industrial covers, not a consumer price list for wheels or patio furniture. The catalog prices powder by the part's surface, the way coaters quote it: $2.50 per square foot. The cover has about 1.35 ft² of surface, both faces and the edges, so it pays $3.38 a piece. A part that has not been measured yet pays $7. The catalog also has a $2.50 piece floor for smaller parts and a 12% invoice fee. It takes the greater of the lot minimum and piece total, then adds the fee.
The final column adds a shop's 30% markup to the outside invoice alone. It pays for administration and whatever margin the shop chooses; it is not a finisher surcharge. Cutting, bending, welding, hardware, transportation and tax are absent. Keep those in their own routing lines so a customer sees a complete manufactured part price.
| Finish | Qty | Vendor lot | Vendor/part | With 30% markup/part |
|---|---|---|---|---|
| Powder coat | 1 | $224.00 | $224.00 | $291.20 |
| Powder coat | 10 | $224.00 | $22.40 | $29.12 |
| Powder coat | 100 | $378.00 | $3.78 | $4.91 |
A true lot-plus-piece agreement costs more
The research assumption of $200 lot plus the piece price is a useful second scenario, but it differs from the default minimum rule. Here we explicitly switch the invoice to additive charging. Both tables use the same 12% fee and the same geometry; their difference comes entirely from the contract wording.
Ask for written confirmation when a vendor says 'minimum $200, $7 each.' That phrase can describe either rule. On a batch of 100 covers, confusing a minimum with an additional setup charge changes the outside invoice before the shop has touched its markup. Do not silently change our pricing engine catalog to resolve an ambiguous email.
| Finish | Qty | Vendor lot | Vendor/part | With 30% markup/part |
|---|---|---|---|---|
| Powder coat | 1 | $227.78 | $227.78 | $296.11 |
| Powder coat | 10 | $261.80 | $26.18 | $34.03 |
| Powder coat | 100 | $602.00 | $6.02 | $7.83 |
Specify what the coater will actually handle
Color, gloss, texture, masking locations, acceptable rack marks and cosmetic faces belong on the purchase order. Tell the vendor whether parts arrive clean and bare or need stripping and repair. A common color on an existing rack may be easier to schedule than a one-off custom powder, but the estimator should get the actual lot price rather than infer a universal discount.
Separate thick coating from precision fits. Identify threads, ground lands, electrical contact points and gasket areas that must remain clear. Budget incoming inspection after coating, especially when a welded box has visible corners or a lid that must still fit. Those are estimator decisions, not capabilities proved by the table.
For repeat work, record how many covers fit a rack and the quantities the vendor actually invoices together. Combining compatible colors may spread a lot minimum, while mixing customers or revisions can create traceability and packing work. Give the buyer a quantity break only when the production and finishing batches support it.
Finish assumptions
- • 12 × 8 × 0.060 in steel cover, priced by its surface; quantities 1/10/100.
- • $200 lot, $2.50/ft² of surface ($7/part before the part is measured), $2.50 piece floor, 12% fee. Default uses max(lot,pieces); alternative explicitly uses lot+pieces.
- • 30% shop markup shown separately. No masking, stripping, freight, tax, production labor or lead-time promise.
| Finish | Qty | Vendor lot | Vendor/part | With 30% markup/part |
|---|---|---|---|---|
| Powder coat | 1 | $224.00 | $224.00 | $291.20 |
| Powder coat | 10 | $224.00 | $22.40 | $29.12 |
| Powder coat | 100 | $378.00 | $3.78 | $4.91 |
