Product mix pricing, the five decisions behind a range and the step gap that decides which tier people buy

Product mix pricing is what you do when you are not pricing one thing. You are pricing a range, and the prices now have relationships with each other that a buyer reads as information. Five distinct decisions sit inside that, and they are named separately because they fail separately. Price lining, also called product line pricing, sets the steps between tiers. Optional product pricing sets the extras. Captive product pricing sets the consumable that the main purchase requires. By product pricing sets what you do with the output you did not set out to sell. Bundle pricing sets the combined offer.

The five decisions, side by side

Price lining, and the step gap that does the work

Price lining means offering the same kind of thing at a small number of set price points. Three tiers, four shirt qualities, two service levels. The point of the exercise is to let a buyer self select by budget without negotiating, and the whole design is in the gaps.

• Three tiers is the practical default. Two forces a yes or no decision and tends to push buyers down. Five or more makes the choice work, and a buyer who cannot choose quickly often leaves instead.
• Each step has to buy something a buyer can name. If a buyer cannot say in one sentence what the next tier adds, the step is a price difference rather than a product difference, and they will take the cheaper one.
• The gap decides the answer, not the prices. A middle tier priced close to the top one pulls buyers up; priced close to the bottom one it pulls them down. This is the single most useful lever in a tiered price list and it is the one most often set by rounding.
• Read the actual distribution before you redesign anything. Count how many customers sit on each tier. A tier with no real customers on it is not a tier, it is an option you are paying to maintain.

The failure specific to price lining is cost creep. When your costs rise, the temptation is to keep the price points and reduce what each one contains, which is invisible in the price list and extremely visible to a repeat buyer. The alternative is to move a price point and say why, which costs a conversation and keeps the range honest.

Optional product pricing, where the attach rate is the whole case

Add ons are priced against a buyer who has already decided. That changes the psychology and it does not change the arithmetic, which is still margin times volume.

Work it out explicitly before you set an add on price. Take the margin you earn per add on, multiply by the share of buyers who take it, and compare that against what a lower add on price would earn at a higher attach rate. The common error is pricing an add on high because the buyer is captive at that moment, which produces a good margin on a small number and leaves most of the opportunity unsold.

Two rules that keep this clean.

• The base price must stand on its own. If the base is only profitable with an add on attached, you have built a partitioned price and a buyer will discover it at the worst moment.
• An add on that most buyers need is not an add on. It is a component of the product being sold separately, and moving it into the base is usually the better decision even though it raises the headline price.

Captive product pricing, and the number a buyer should be given

Captive pricing is the printer and the cartridge, the machine and the consumable, the platform and the per seat charge. The main item is priced low or moderately and the money comes from what the buyer has to keep buying.

It is a legitimate model and it has one fragile point. The buyer's real cost is the total over the life of the item, and the moment they work that out is the moment they look for an alternative consumable or a different supplier. So the decision is not whether to price this way, it is whether you can defend the consumable price against a substitute.

The version that holds up publishes the total cost of ownership itself. Stating what the first year costs including consumables reads as confidence and removes the discovery, and in business to business purchasing it is increasingly expected rather than optional. The version that fails hides the consumable price until after the main purchase, which works once per customer.

By product pricing, which is free money with one condition

A by product is something your main activity produces that you did not set out to sell: offcuts, data, residual capacity, a tool you built internally. The arithmetic is unusually simple. Any price above the cost of handling it improves the economics of the main business, so almost any sale is a good sale.

The one condition is that selling it must not damage the main product. Residual capacity sold cheaply to a buyer who would otherwise have paid full price for the main offer is not a by product sale, it is a discount with extra steps. Keep the two audiences separable, and if they are not, price the by product high enough that it stops being an alternative route to the main thing.

Bundles, and the attach question first

A bundle moves the comparison, because once your package holds four things and a rival's holds three different things, prices stop being directly comparable. That is the real effect and it is legitimate when the bundle suits the buyer.

Before building one, run the check that decides whether it earns anything. Add up what the components are worth separately, subtract the bundle price, and that difference is what the bundle costs you per sale. Then ask what share of those buyers would have bought the second component anyway. A bundle discounting something your buyers were already purchasing is a price cut in a package. A bundle moving something nobody was choosing is a genuine widening of the business.

The adjacent case where one item is deliberately priced below its own cost to pull in a profitable second sale is a different tactic with its own conditions, and we cover it in loss leader in marketing, how the tactic works, when it pays and the lines not to cross.

A sequence for designing a range

• Write the margin per unit for every item first. The relationships between prices are only safe to design once you know what each one earns.
• Decide the number of tiers and name what each step buys in one sentence a buyer would recognise. If you cannot write the sentence, merge the tiers.
• Set the gaps deliberately and predict which tier most buyers should land on. That prediction is testable within a quarter.
• Separate genuine add ons from components and move the components into the base.
• Publish the total cost over a year wherever a consumable or a per seat charge is involved.
• Count the customers per tier after a quarter and compare with the prediction. The gap tells you whether to move a price or to change what a tier contains.

Where you are pricing a service rather than a product, the hardest part is deciding what the unit even is, because an hour, a deliverable and an outcome produce three different price lists for the same work.

Questions about product mix pricing

What is price lining in simple terms

Offering the same kind of product at a small number of fixed price points so a buyer can choose by budget without negotiating. The design decision is the gap between the points, not the points themselves.

How many tiers should a price list have

Three works for most businesses. Two pushes buyers down, and five or more makes choosing hard enough that some buyers postpone. Every tier has to add something a buyer can name in one sentence.

What is the difference between optional product and captive product pricing

An optional product is something the buyer may add. A captive product is something the main purchase requires in order to keep working. The second one obliges you to publish the cost over time, because the buyer's real number is the total rather than the first invoice.

Should a bundle always be cheaper than the parts

It usually is, and the question worth answering first is what that discount costs you per sale and what share of buyers would have bought the second item anyway. If most of them would, the bundle is a price cut rather than a new offer.

How do I price a by product

Above the cost of handling it, and high enough that it does not become a cheap route to your main product. Within those two limits almost any price improves the overall economics.

What should I do when costs rise across a range

Move a price point and say why, rather than keeping the price and quietly reducing what the tier contains. A repeat buyer notices the second one immediately and it costs more trust than a stated increase.

The tier a buyer is put in before they see your range

A product range is a structure a buyer walks through, comparing steps and choosing. That walk is skipped when somebody asks an assistant which option suits a business like theirs and gets one recommendation back, naming a company and sometimes naming a tier. The step gaps you set, the add ons you separated and the total you published are inputs to that recommendation rather than a page the buyer reads, and a range described from stale sources can have a buyer steered to a tier you no longer sell. What is being said about your range, and by which sources, is a thing to read rather than infer. AI Knows Us takes that reading across ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews, so the recommendation your range is producing stops being invisible to the people who designed it.
