Comparing Packaging Machinery Quotes on a Like-for-Like Basis

Three suppliers send quotes for the same kind of machine, and the prices differ by 30 percent or more. Before you pick the lowest, check whether it really is the lowest cost or whether the quotes just cover different things.

Put every quote on the same scope first. Add each missing item at your own estimated cost, and the ranking can change. In the worked example below, the cheapest headline price ($72,000) becomes the second-cheapest normalized total, and an $8,000 advantage turns into a $2,600 deficit. That comparison is a price analysis; a later section explains when a buyer also needs a cost analysis of the elements inside a quote.

Why quotes are hard to compare

A quote describes what the supplier will do for a price, and suppliers describe different things. Five differences cause most of the trouble.

Scope comes first. One quote includes change parts for each pack format, factory acceptance testing, training and an initial set of spares. Another lists only the machine. Silence in a quote is not a zero, and it is not an inclusion either.

Trade terms are next. One price is ex works, another is delivered to your dock (see the ICC Incoterms rules). The freight, insurance and handling in between cost the same money whoever invoices them. Imported Equipment Costs Beyond the Factory Price shows how the terms move cost between buyer and seller.

Performance claims are a third. A rated speed of 60 packs a minute doesn’t say which product, pack or film it was measured on, or what the line around the machine can use, a point covered in Why Faster Machines Do Not Always Increase Line Output.

Then acceptance terms. Some quotes define a pass in numbers, such as output and reject rate over a fixed run. Others say only that the machine will be “tested”.

Last, warranty, spares and service. Warranty length, what it covers, who pays for travel and shipping of parts, and response times all vary, and none of them appear in the machine price.

Step 1: write your requirement sheet first

Don’t let a supplier’s quote template define the job. Write a one- or two-page requirement sheet and send the same sheet to every supplier. It should state:

• the product and its relevant properties (size, weight, stickiness, fragility);
• pack sizes and formats, and how many you must run on day one and within two years;
• target good output per shift, not rated machine speed;
• packaging materials, including the film or container specification;
• utilities available at the site (voltage and phase, compressed air, water);
• upstream and downstream equipment the machine must connect to;
• standards your market requires, such as electrical and machine-safety rules;
• the language of manuals and software.

Ask each supplier to answer in your format, line by line, and to say so wherever they swap a requirement for an alternative.

If the quotes cover different machine types or pack formats, such as rollstock forming against premade pouches, compare the packaging systems first; Rollstock Versus Premade Pouches: Comparing the Total Packaging Cost shows how.

Step 2: normalize scope with a table

Build one table with the same rows for every supplier. Each cell holds one of three entries: included, excluded, or priced separately with the amount. Then add every excluded item at your own estimate, marked as an estimate.

Typical rows:

• machine and options;
• change parts for each format;
• integration items (infeed, discharge, interfaces);
• freight and trade term;
• installation and commissioning days;
• training;
• factory acceptance test (FAT) and site acceptance test (SAT);
• documentation;
• initial spare parts;
• warranty length and what it covers;
• response times;
• software and remote support.

The formula is simple:

Normalized total = Headline price
                 + Items priced separately (supplier's figure)
                 + Items excluded (your estimate)

Some costs fall on your site whichever supplier you choose (utilities, layout, rigging); The True Installed Cost of Packaging Automation covers them. They are the same across suppliers and can be left out of the comparison, unless a supplier’s design changes them.

A worked example

Worked example with three quotes labeled A, B and C. Replace each line with the supplier’s written quote.

Requirement: three pack formats (the first format’s tooling comes with the machine), delivered to your dock, five commissioning days, operator training, a FAT and an initial spare parts set.

Your estimates for items a quote leaves out: change parts for two extra formats $2,300, freight to site $2,500, commissioning at $1,000 per day, training $1,200, FAT cost (travel and test material) $1,300, initial spares $1,500.

The arithmetic, line by line:

A: $2,800 + $2,500 + $6,000 + $1,200 + $1,300 + $1,500 = $15,300
   $72,000 + $15,300 = $87,300
B: $2,000 + $1,200 + $1,500 = $4,700
   $80,000 + $4,700 = $84,700
C: $2,500
   $95,000 + $2,500 = $97,500

The headline order was A, B, C. The normalized order is B, A, C. Supplier B is now $2,600 below A ($87,300 - $84,700), where it was $8,000 above on headline price. The gap between B and C narrows from $15,000 to $12,800 ($97,500 - $84,700).

That doesn’t make B the better supplier. The table ranks scopes at your estimated prices and says nothing yet about performance, warranty or reliability.

Price analysis or cost analysis: which one a quote review needs

The normalization table above is a price analysis. It compares what each supplier asks for a defined scope and never asks what the machine costs the supplier to build. A cost analysis goes one level down and examines the elements that make up a price. Both terms are defined in the U.S. Federal Acquisition Regulation, in FAR 15.404-1:

• Price analysis is “the process of examining and evaluating a proposed price without evaluating its separate cost elements and proposed profit.”
• Cost analysis is “the review and evaluation of any separate cost elements and profit or fee in an offeror’s or contractor’s proposal,” used to judge whether a price is fair and reasonable or whether proposed costs are realistic.

The definitions come from U.S. federal government contracting. FAR 15.404-1 tells federal contracting officers how to evaluate offers, and when each analysis is required depends on federal rules about certified cost or pricing data. None of that binds a private company buying a packaging machine. The distinction is still useful, because it separates two different questions a buyer can ask of a quote.

The techniques FAR lists for price analysis translate directly. Comparing competing quotes is what Step 2 does. Comparing with prices paid before is valid only after adjusting for differences in terms, quantities and timing, which FAR also requires. FAR’s “rough yardsticks”, such as dollars per pound or per horsepower, are meant to flag inconsistencies that need a question, not to set a price. And an independent estimate is your own bottom-up figure, built as in The True Installed Cost of Packaging Automation.

Cost analysis earns its place when competition does not do the work. If only one supplier can build the machine, there is no competing price to compare, and the remaining check is whether the parts of the price make sense. A supplier may decline to show its internal costs. You can still examine the elements a quote does itemize. In the worked example, Supplier A charges 5 commissioning days at $1,200, or $6,000, against your estimate of 5 days at $1,000, or $5,000. That $1,000 difference is a cost-element question: does the day rate include travel and accommodation, and what happens if commissioning needs a sixth day?

Cost analysis in this procurement sense is also different from a manufacturing or production cost analysis of your own product. That second kind asks what each pack costs you to make; Cost per Good Pack covers it.

Step 3: compare performance on the same basis

Ask every supplier to show speed and reject rate on your product and pack, in a sample test or FAT. Count good packs over a fixed run time, for example 60 minutes, with the same material in each test. A rated speed on a different product is no basis for comparison.

Then turn the differences into cost with cost per good pack, a method covered in Cost per Good Pack: A More Useful Measure Than Nameplate Speed. A simple version for rejects:

Packs run = Good packs needed / (1 - reject rate)
Rejects   = Packs run - Good packs needed
Annual reject cost = Rejects x material cost per pack

Worked example: 1,200,000 good packs a year, $0.10 of material and product lost per rejected pack, and reject rates of 4 percent (A), 2 percent (B) and 1 percent (C). Replace each rate with a trial on the plant’s own product.

On these assumptions A costs about $2,550 a year more than B in rejects ($5,000 - $2,450), which widens B’s lead. Reject cost is only one term; speed differences, downtime and labor belong in the same per-good-pack view.

Step 4: acceptance and payment terms

Define acceptance in writing before you sign:

• the output required, as good packs over a stated run time;
• the maximum reject rate, and how rejects are counted;
• the product, pack and material used in the test;
• the run duration, long enough to show stable running rather than a good first ten minutes.

Tie payment milestones to those tests, for example a deposit with the order, a payment after FAT, a payment on delivery, and a retention held until SAT passes. Settle in the contract who pays if a test fails: repeat travel, re-test, and the cost of waiting. The size of the retention and the legal wording are for you to negotiate, with your own legal review.

Step 5: costs that arrive after delivery

The purchase price is one slice of the total. Ask each supplier for these:

• prices and lead times for wear parts and the recommended spares list;
• service rates per day, travel and accommodation rules, and response times;
• consumables the machine needs, such as ribbons, blades or seals, and their prices;
• software update policy and whether remote support carries a fee after the warranty ends.

These items rarely change the first-year ranking much, but over several years they can. To turn a total cost into a payback figure, see Automation Payback, ROI and TCO: What Each Metric Tells You.

When the conclusion changes

The table changes if your estimates are wrong. If you already hold spares, your own technicians commission machines, or you ship freight in your own truck, the excluded items may cost far less than assumed. If a supplier’s design needs a different utility connection or conveyor, site costs are no longer equal. Before committing to buying at all, check whether contract packing would cost less at your volume. Where quotes mix currencies or trade terms, normalize those first.

Checklist

• Requirement sheet written first and sent unchanged to every supplier.
• Every quote entered in the same table, with every row filled in.
• Excluded items priced at your own estimate, labeled as estimates.
• Trade term and delivery point identical across quotes.
• Speed and reject rate measured on your product, in good packs over a fixed time.
• Acceptance criteria and payment milestones in writing.
• Spares, service rates, lead times and consumables priced.
• Where only one supplier quotes, or extras are priced separately, the itemized elements checked against your own estimate.
• Reference check and sample test done on the supplier with the lowest normalized total.

The lowest normalized total still needs a reference check and a sample test. The model ranks scopes at your estimated prices; it can’t judge supplier reliability, and this site does not recommend suppliers.

Assumptions and limits

• Replace the dollar amounts, reject rates and volumes with the written quotes and the plant’s measured reject rates.
• Missing items are priced with the buyer’s own estimates, which may be wrong. Rerun the table when real prices arrive.
• The model ignores taxes, financing, the time value of money, ramp-up and residual value.
• Warranty length, response times and software support are compared as text. They are not priced in the example.
• It ranks scopes and costs, not supplier reliability, and it does not recommend any supplier.
• Treat it as a comparison tool, not financial, legal, safety or engineering advice.
