How to Compare Print Quotes for a Multi-SKU Program

The useful answer is simple: do not compare multi-SKU print quotes by unit price alone. Put every vendor’s proposal into one worksheet that uses the same SKU quantities, material construction, tooling assumptions, delivery schedule and reorder scenario. Then compare total delivered cost, cash committed and inventory exposed to obsolescence.

This matters because two quotes can describe the same nominal program while pricing very different production plans. One vendor may combine versions digitally, another may charge separate flexographic plates, and a third may substitute a different adhesive or ship the entire annual quantity at once. Those are operating differences, not accounting details.

The short answer

Issue one bid sheet with a separate row for every SKU and version.
Lock the physical specification before evaluating price.
Separate one-time tooling and prepress from recurring production charges.
Compare the quoted initial order and at least one realistic reorder scenario.
Add freight, storage, spoilage and obsolete inventory to the printed price.
Document ownership and reuse terms for plates, dies and structural tooling.

Start with one quantity matrix

A total such as “250,000 labels” is not enough. A program containing five SKUs at 50,000 each has a different production and inventory profile from one containing a 200,000-unit core SKU and four 12,500-unit versions. Give every bidder the annual forecast, initial release quantity and quantity by artwork.

Identify the number of distinct artworks, shared and unique dielines, shared and unique materials, and any variable-data requirement. Digital and hybrid label systems are positioned for versioning, shorter runs, variable data and faster changeovers, while flexographic production requires process-specific prepress and plates. That does not establish one universal cost crossover; it means the production process must be visible in the quote.

For a deeper cost model, use the same variables covered in this guide to breaking custom-label quotes into comparable cost drivers. If business stickers or roll labels form part of the bid, CustomStickers can also be included as a clearly specified quote option rather than compared against an incomplete scope.

Normalize the quote line by line

Cost area	What every vendor should state	Common comparison error	Reorder question
Artwork and prepress	Files covered, proof type, revisions and preflight work	Treating bundled setup as free	Is prepress charged again for an unchanged file?
Plates and tooling	Plate, die or cutting-form charges by SKU	Comparing one bundled fee with itemized tooling	Who owns and stores each tool?
Material construction	Facestock or board, adhesive, liner, coating and finish	Accepting “white film” or “corrugated” as complete specifications	Can the same construction be reordered without substitution?
Production	Quantity by SKU, process, makeready and overs policy	Dividing the entire program by one total quantity	What changes when only one SKU is reordered?
Packing and freight	Cartons, pallets, origin, delivery terms and accessorials	Comparing delivered pricing with ex-works pricing	Can releases be consolidated or staged?
Inventory	Shipment schedule, supplier-held stock and storage charges	Ignoring cash and obsolete-version exposure	What inventory remains if artwork changes?

Separate fixed production costs from run costs

For flexographic labels, ask vendors to separate artwork preparation, proofing, plates, press makeready and production instead of using one undifferentiated setup line. Digital printing does not use printing plates, but that does not make its prepress, finishing or changeover work costless.

Packaging tooling needs the same treatment. Depending on the process, tooling can include flexographic plates, cylinders, flexible or solid dies, and cutting or creasing forms. Corrugated conversion may include printing, die-cutting, folding and gluing, while finished packaging is generally delivered flat and palletized. The FEFCO overview of corrugated production provides useful process context.

Record who owns each tool, where it is stored, how long it will be retained and what changes require replacement. A low first-order price is less attractive if every artwork adjustment triggers new plates or if an inaccessible die prevents competitive reordering.

Lock the complete material and application specification

For pressure-sensitive labels, compare the complete construction: facestock, adhesive, liner, laminate or coating, dimensions and the package surface. PET and glass are higher-surface-energy substrates than materials such as HDPE, LDPE and polypropylene, so two adhesives described only as “permanent” are not necessarily equivalent.

The bid sheet should also state whether labels are applied by hand or machine, the container geometry, application temperature and expected moisture or service exposure. Cold or wet application conditions can reduce initial tack. For machine-applied rolls, specify core size, maximum outer diameter, labels per roll, gap or pitch, orientation and unwind direction. Use a documented roll-label unwind requirement rather than relying on a visual guess.

Treat verification and compliance as priced deliverables

If a SKU carries a barcode, specify its symbology, size, placement, quiet-zone allowance, background, contrast and any varnish or laminate over the code. Package shape, curvature, sheen and barcode placement can affect scanning. Ask whether the quote includes a production verification report, especially when introducing or modifying a code. The GS1 implementation guidance recommends verification for new or changed barcodes.

For food-contact applications, request documentation for the actual finished construction and intended use. The FDA’s food-packaging information explains that packaging components can include adhesives and colorants and that food-contact substances subject to food-additive requirements must be authorized for their intended use. Generic “food-safe” wording is not a substitute for construction-specific documentation.

Add freight, storage and inventory risk

Require the shipping origin, carton and pallet counts, delivery terms, accessorial charges and release schedule. Carriers may price freight using actual or dimensional weight, whichever is greater, so a lightweight but bulky packaging shipment can still carry a substantial freight charge. Compare delivered cost to delivered cost, not a factory price to a landed price.

Storage also belongs in the comparison. Record pallet footprint, cartons per SKU, shelf life, environmental requirements and whether the vendor can hold inventory for staged releases. Avery Dennison, for example, publishes supplier-specific storage recommendations of 15–25°C and 35–65% relative humidity for its self-adhesive materials; those values should not be treated as universal requirements for every stock.

More importantly, estimate what becomes obsolete after an ingredient, regulatory, barcode or design change. Standardizing shared components can reduce that exposure, particularly when the same carton, insert or base label works across several products. This approach is developed further in the guide to standardizing ecommerce packaging components.

Compare the first order and the likely reorder

Build at least two totals. The first should cover the initial program: prepress, proofs, tooling, production, packing and delivered freight. The second should model a realistic reorder, such as one fast-moving SKU replenished alone while slower versions remain in stock.

For each scenario, calculate total delivered cost divided by usable units received. Keep setup and tooling visible beside that figure, and add expected storage charges and obsolete inventory as separate risk lines. Do not spread a one-time die across an optimistic lifetime volume unless the tool ownership, usable life and forecast are documented.

Make the award from a controlled comparison

Send vendors the same revision of the specification and require them to list every exception or substitution. Reject silent material changes, unclear tooling ownership and freight marked merely “additional.” Then award the program using the scenario that resembles how the business will actually buy: mixed initial launch, uneven SKU replenishment, staged delivery and occasional artwork changes.

The next step is to create one SKU-level bid sheet and ask each vendor to return it with no blank fields. Once quantities, construction, tooling, delivery and reorder assumptions are normalized, the lowest-cost production plan usually becomes much easier to identify—and much harder to disguise behind a deceptively low unit price.
