B2B Loyalty Programs: What Tiered Discounts, Rebates, and Perks Achieve

Why rebate programs are common in B2B and rarely checked

In many business relationships, a discount is part of the standard package: three percent above a certain order quantity, a rebate at year end, a framework agreement with special terms. These rules were usually introduced because a large customer asked for them or a competitor offered something similar. After that they keep running, year after year, without anyone calculating whether they have kept a single customer.

The guiding question of this article is therefore: What do tiered discounts, rebates, and perk programs actually achieve with business customers, and when do they pay off? To answer it, we first clarify the terms, then introduce a mental model, the three types of switching costs, review what studies show about loyalty programs, and finally calculate what a rebate costs.

A rebate the customer would have earned anyway does not bind them. It pays them for staying, which they would have done regardless.

Terms: tiered discount, rebate, perk program

A loyalty program is a fixed rule under which a customer receives something in return for repeated or larger purchases. Belli and colleagues (2022) adopt a common definition: a long-term incentive system intended to strengthen buying behavior over time. In business markets, three basic forms can be distinguished.

These programs differ from the discount in an individual quote in that they are fixed in advance and apply to all customers in a group. How individual discounts are managed is described in the guide Controlling discounts. This article is about rules meant to work beyond a single order.

The mental model: three types of switching costs

A customer stays when switching to another supplier costs them more than they gain. Burnham, Frels, and Mahajan (2003) sorted these switching costs into three types. Procedural switching costs are time and effort: searching for, evaluating, and onboarding a new supplier and changing routines. Financial switching costs are monetary values lost when switching, such as an accumulated rebate. Relational switching costs are the discomfort of giving up an established relationship with people and with a familiar supplier.

The model explains why many loyalty programs work less well than hoped. A cash rebate creates almost exclusively financial switching costs, and that is exactly the type a competitor can offset immediately with a better offer. Procedural and relational switching costs, by contrast, arise from good work: from smooth processes and from people who know the customer. They are more expensive to build but harder to copy.

What research shows about loyalty programs

Dowling and Uncles (1997) produced one of the best-known skeptical assessments. They name three goals companies use to justify programs: defending existing sales and margins, increasing the value of existing customers, and encouraging the purchase of further products. Their finding is sober: most programs do not fundamentally change the structure of a market. They may protect incumbents, but at the cost of higher marketing expenditure. For a program to work, the authors argue, it must enhance the overall value of the offering rather than simply place an extra incentive next to it. One detail in their text stands out: in business markets, loyal customers have always been treated better than spot buyers. The idea is older there than any points program.

Belli, O’Rourke, Carrillat, Pupovac, Melnyk, and Napolova (2022) summarized thirty years of research in a meta-analysis: 429 effect sizes from 110 papers published between 1990 and 2020. They find strong evidence that programs increase customer loyalty. However, they mainly affect behavior, meaning purchase volume, frequency, and retention, and have a clearly weaker effect on attitudes toward the supplier. How strongly they work depends on design: on the program’s structure, the type of reward, and when and how it is delivered. The authors also describe that, besides financial and procedural switching costs, programs can create a habit of staying with the supplier.

A third study shows what this mechanism looks like in practice. Bolton, Kannan, and Bramlett (2000) analyzed data from a global financial services company with a rewards program. Program members gave less weight to bad experiences with the company relative to competitors than non-members did. The program cushions frustration. But it can also mean that a supplier notices problems later, because customers stay for the time being despite their dissatisfaction.

The limits of these findings are clear. Most studies come from retail, airlines, and financial services with many consumers. For small B2B businesses with a few dozen important customers, there is hardly any robust research. The direction can be transferred; the magnitude cannot.

Two views: loyalty or paid habit

The first view considers programs effective and points to the meta-analysis. Someone who has a rebate in prospect concentrates purchases, buys more often, and stays longer. In B2B, buyers are also measured on terms. An annual rebate is a result they can show, and therefore a reason to stay with the supplier.

The second view calls this paid habit. If programs mainly change behavior and barely change attitudes, the customer stays only as long as nobody offers more. A competitor simply has to outbid the rebate. Dowling and Uncles describe the consequence: in the end every supplier in a market has a program, costs have risen, and customers are distributed as before.

I consider both readings correct, but for different parts of a program. Monetary rewards are often an entry ticket in B2B without which a supplier is not even considered by larger customers. They rarely keep the customer. What keeps them is what Friend and Johnson (2017) found missing with lost business customers: attention, flexibility, and solved problems. The guide Why customers leave describes these findings in detail.

What a rebate costs: the windfall calculation

A rebate on revenue comes entirely out of the contribution margin. For it to pay off, it must trigger additional purchases that would not have happened without it. Everything the customer would have bought anyway is a windfall. The required additional volume follows the same formula as in the guide on discounts: rebate ÷ (margin − rebate).

An example with freely chosen figures: a customer buys 80,000 euros a year, the margin is 25 percent, so the contribution margin is 20,000 euros. An annual rebate of 2 percent costs 1,600 euros, which is 8 percent of the earnings from this customer. For the rebate to pay for itself, the customer would have to buy about 7,000 euros more than without it. If they would have ordered the 80,000 euros anyway, the rebate is a pure loss.

The calculation shifts if the rebate prevents churn. How much a retained customer is worth is shown in the guide Calculating customer lifetime value: the expected lifetime is roughly 1 ÷ (1 − repurchase rate). If a program raises the repurchase rate from 75 to 80 percent, the average relationship lengthens from four to five years. That is the yardstick a program must be measured against, and it requires actually measuring the repurchase rate before and after.

A program that builds loyalty: five design rules

Five rules can be derived from the switching cost model and the findings. They apply to a new rule as well as to reviewing an existing one.

1. Define the goal

   Should the program prevent churn, concentrate purchasing, or encourage additional purchases? Each goal has a different measure: repurchase rate, share of the customer’s purchasing, number of service types bought.

2. Reward what is additional

   Monetary benefits only start above previous purchase levels. A tier that already applies at today’s revenue pays for windfalls.

3. Combine money with service

   Supplement or replace part of the rebate with services that build procedural and relational switching costs: a named contact, priority scheduling, onboarding new staff at the customer.

4. Keep it simple

   A customer must understand the rule in one sentence. Complicated tiers with exceptions are treated by purchasing as bargaining chips, not as incentives.

5. Review annually

   Compare repurchase rate, share of purchasing, and contribution margin of participants with the previous year. A program without a review date becomes an entitlement.

Perk programs suit businesses with ongoing service particularly well. If you offer maintenance or service, you can build priority during breakdowns or plannable appointments into a contract, as the guide Selling service contracts describes. Such perks use capacity, but they bind through service instead of money.

Conclusion and next steps

What do tiered discounts, rebates, and perk programs achieve in B2B? Research shows that loyalty programs do change buying behavior but barely change attitudes toward the supplier. Monetary rewards mainly create financial switching costs that a competitor can outbid, and they cost a fixed share of the contribution margin every year. A program becomes worthwhile when it rewards additional rather than existing purchases, combines money with service, and is measured against the repurchase rate. If you want to keep customers, you are better off investing in processes and named contacts than in higher percentages. How to organize the care of existing customers in daily work is shown in the guide Growing existing customers.

• All current tiers, rebates, and special terms are recorded in one list.
• For each program, you know what it cost last year.
• The repurchase rate of participants has been compared with that of other customers.
• Rebates only start above previous purchase levels.
• At least one benefit is based on service rather than money.
• There is a fixed annual review date.

1. This week: List all tiered discounts and rebates and calculate what they cost last year.
2. Next week: For your twenty largest customers, compare the repurchase rate of participants and non-participants.
3. In a month: Convert the most expensive rule into a rebate above previous purchases, or add a service benefit.

You can recognize a good loyalty program by the fact that the customer would miss something that is not on the invoice if it were abolished.
