Why B2B Sales Incentive Plans Fail: 7 Common Mistakes and How to Fix Them

A salesperson closes a $500,000 contract and earns a substantial commission. The sales team celebrates, but Finance later discovers that heavy discounting has left the business with little profit. Elsewhere, two account managers claim commission on the same customer, and a third salesperson delays signing a contract because the following quarter offers a more favourable payout.

These situations are not always the result of poor performance or employee behaviour. Often, the sales incentive plan is rewarding outcomes the business did not intend to encourage.

For B2B businesses, where sales cycles can be long, contracts may involve several employees and customer relationships can continue for years, these design weaknesses become particularly expensive. Here are seven common problems and practical ways to address them.

1. Paying commission on revenue without considering profitability

A revenue-based commission is easy to explain and administer, which makes it attractive to many businesses. However, it can also reward a salesperson for winning work that contributes relatively little profit.

Consider two contracts with the same revenue but different margins.

Illustrative figures, not market benchmarks.

Both deals generate the same commission even though Deal B produces twice the gross profit. This does not mean every business should pay commission directly on profit: salespeople may have little control over costs, and margin data may be unavailable until after the sale.

What to do instead: Ask Finance to model the incentive cost against actual deal margins. Depending on what salespeople can control, consider minimum margin requirements, discount approvals or a modest margin-related measure alongside revenue. Make the calculation transparent before changing the plan.

2. Rewarding a signed contract before the revenue is secure

Long B2B sales cycles create a difficult question: when has someone earned commission? At contract signature, customer onboarding, invoicing, payment or another defined milestone?

If the plan pays the full amount immediately upon signature, employees may receive commission on deals that are later cancelled, reduced or never implemented. Waiting until every dollar is collected can create a different problem, particularly where the salesperson has no control over billing or collections.

What to do instead: Choose a crediting and payment point that reflects the sales cycle and the risk the business can reasonably manage. A defined milestone approach, such as part of the incentive on an eligible signed deal and the balance after implementation, may suit some businesses. Explain cancellations, refunds, amendments and any later adjustments clearly in the written terms, with contractual and legal review where appropriate.

3. Using the same incentive plan for every sales role

A Business Development Manager pursuing new customers has a different job from an Account Manager responsible for renewals. Yet many companies put both on the same revenue target and commission rate.

This can lead account managers to prioritise easy renewals while new-business roles chase contracts without considering long-term customer value. It can also make the plan seem unfair when one role has greater control over sales outcomes than another.

What to do instead: Identify the main responsibilities of each role before choosing the measure.

These are possible measures, not fixed rules. Choose measures only where performance can be reliably recorded and meaningfully influenced by the role.

4. Creating disputes over who gets credit for a sale

A new-business salesperson introduces a customer, a solutions specialist helps negotiate the contract and an account manager takes responsibility after implementation. When the customer expands its contract, who earns commission?

Without a clear answer, the business risks paying multiple full commissions on the same revenue or creating conflict between employees who were all essential to the outcome.

What to do instead: Establish written rules for account ownership, shared deals, territory changes, handovers and renewals. Agree on any split credit as early as practicable, document it in the CRM or deal approval process and ensure Finance can model the total incentive cost. Where collaboration is central to the business model, a defined team measure may sometimes work better than individual deal credit.

5. Introducing accelerators without modelling the cost

Accelerators increase the payout rate when performance exceeds a target. They can be effective, but an attractive payout curve is not necessarily an affordable one.

Imagine a salesperson with a $60,000 target annual incentive. The plan pays 100% of that incentive at target and 200% at 120% quota achievement. At 120% attainment, the incentive would be $120,000, before considering the employee's fixed remuneration. If several employees exceed target at once, incentive costs may be materially higher than the original budget.

Higher payouts may be commercially justified when the additional sales are sufficiently profitable. The risk arises when no one has tested what the plan would pay in exceptional scenarios.

What to do instead: Model results below target, at target and substantially above target. Include unusually large contracts, discounting, multiple employees reaching accelerators and revenue subsequently reversing. Finance should review the expected and maximum plausible cost before the plan is launched.

6. Setting targets that employees cannot reasonably influence

A sales target can look achievable in a spreadsheet while being unrealistic for the territory, customer base or length of the sales cycle. Conversely, a well-established territory may offer easier access to revenue than a new market.

When targets ignore these differences, employees may stop seeing the plan as a fair reflection of their contribution. Managers may then spend more time negotiating exceptions than managing sales performance.

What to do instead: Use historical results, pipeline quality, market potential, customer assignments and the sales cycle to test quotas. Explain how targets will be handled for new starters, extended leave, territory changes and material reorganisations. Avoid changing targets retrospectively without reviewing contractual obligations and the impact on employees.

7. Writing incentive rules that nobody can consistently interpret

Even a commercially sound incentive formula can fail if the plan document is ambiguous. Disputes often arise over what qualifies as a sale, when commission becomes payable, whether a customer is considered new or existing, and what happens when an employee leaves.

Employees should not have to rely on an informal explanation from their manager to understand how their incentive will be calculated.

What to do instead: Include definitions, eligibility, performance periods, crediting rules, payout calculations, worked examples, adjustment processes and dispute resolution arrangements in the plan document. Use plain language and test the rules against actual scenarios before employees receive them.

For Australian employers, commission arrangements must also be considered alongside employment contracts, applicable awards or enterprise agreements and minimum employment entitlements. The Fair Work Ombudsman guidance on commission payments explains that commission may be paid on top of wages and that commission-only arrangements are subject to additional requirements. An attractive earning opportunity does not remove the need to meet applicable minimum entitlements.

How to test your existing B2B sales incentive plan

Before redesigning everything, take three to five actual deals from the previous year and ask your Sales, Finance and HR teams to review how the plan treated them.

Choose examples that expose different risks: a heavily discounted contract, a multi-person sale, a deal later cancelled, a large contract that triggered an accelerator and a customer renewal.

For each case, answer these questions:

1. What behaviour and commercial outcome did we want to encourage?
2. What commission did the plan actually produce?
3. Did that payout make commercial sense given margin, delivery risk and customer value?
4. Could the employee have predicted the result from the written rules?
5. Would we be comfortable applying the same rule consistently to other employees?

If the answers reveal a problem, change the relevant design rule rather than adding an extra layer of complexity across the entire plan.

A practical checklist before approving the next incentive plan

• Each sales role has measures linked to outcomes it can influence.
• Revenue and incentive costs have been tested against profitability.
• Crediting and payment milestones are documented.
• Shared deals and account ownership have clear rules.
• Quotas and accelerators have been modelled using realistic scenarios.
• New starter, leaver, leave and territory change arrangements are addressed.
• Finance can reproduce the calculations from reliable data.
• Employees can understand the rules and see worked examples.
• HR or legal advisers have reviewed employment obligations where necessary.

Fix the design before increasing the commission rate

When a sales incentive plan fails to motivate employees, increasing commission rates is often the first suggestion. However, larger payouts will not necessarily fix poor targets, inconsistent crediting or incentives that reward unprofitable sales.

A better starting point is to establish where the current plan creates the wrong outcomes and test the financial and behavioural impact of changing those rules. In many cases, a clearer measure, better definition or more appropriate payment milestone will achieve more than an additional commission percentage.

Frequently asked questions

Should B2B sales commission be based on revenue or profit?

Neither is automatically best. Revenue is often easier to measure, while profit measures can better reflect deal quality. Consider what the salesperson can influence, the reliability of the data and whether a margin requirement would be clearer than paying entirely on profit.

What is a sales incentive accelerator?

An accelerator increases incentive earnings once an employee reaches a specified level of performance. The payout curve should be financially modelled before implementation.

How do you prevent commission disputes on shared deals?

Define account ownership, eligibility and split credit in advance, record the decision in the relevant system and apply the rules consistently.

Can an Australian employee be paid commission only?

Commission-only arrangements are subject to applicable award, agreement and minimum wage rules. Employers should check Fair Work's official guidance and the employee's particular circumstances.

How often should a B2B sales incentive plan be reviewed?

Review performance and exceptions during the year, then assess design effectiveness before the next plan cycle. Changes should be managed transparently and consistently with the applicable contractual and employment obligations.
