How to Build a B2B Sales Commission Plan: SME Guide
Strategy
A B2B sales commission plan is a compensation system that splits a sales rep's total earnings into a fixed base salary and target-linked variable pay, and sets out in advance, through written rules, which sales are rewarded, at what rate and when. For SMEs, a good plan rests on five pillars: a role-based fixed-to-variable ratio, a realistic quota, a commission rate that protects company profitability, a payment schedule tied to collections, and rules simple enough for everyone to understand them the same way. Once these five are in place, the commission plan stops being a cost item and becomes the company's most powerful steering tool.
In many SMEs, the commission scheme is decided in a hurry when the first sales rep is hired. As the team grows, it turns into a structure riddled with exceptions along the lines of "here's what we promised Mr. Ali last year," and nobody fully understands it. In this guide, we walk you step by step, with sample calculations, through building a sustainable commission plan, whether you're starting from scratch or revising your current one.
Why is a sales commission plan so critical for SMEs?
In large enterprises, the commission plan is usually a joint product of HR, finance and sales operations. In SMEs, the job mostly lands on the desk of a co-founder or sales manager. Yet a poorly designed plan damages a small company much faster:
- It rewards the wrong behavior. A plan that pays bonuses on revenue alone pushes reps to close deals with excessive discounts. Revenue grows, profit erodes.
- It drives away top performers. Plans with a cap lead the best sellers to decide mid-year that "it's no longer worth the effort."
- It disrupts cash flow. Paying commission on sales that have been invoiced but not collected creates a serious cash problem, especially in industries that operate on payment terms.
- It undermines trust. If reps can't calculate their own commission, the plan won't generate motivation, no matter how generous it is.
In short, your commission plan is your sales strategy reflected on the payroll. If your plan doesn't clearly state which customers, which products and at what price you want to sell, your team will decide that based on their own interpretation.
Which commission model is right for your business?
There is no single "right" model. The length of your sales cycle, your product margins and your team's maturity determine the model. These are the models most commonly used by SMEs:
Base salary + commission
The most common model, and the most balanced for most B2B SMEs. The rep receives a regular salary and earns variable pay based on sales performance. In sales with long cycles and multiple decision-makers, it provides the rep with financial security.
Quota-based commission
The rep has a quota for a given period, and commission is calculated based on quota attainment. For example, a rep who reaches 80% of quota receives a set portion of their variable pay, while one who reaches 100% receives all of it. It is the most measurable model from a performance management standpoint.
Tiered (accelerated) commission
The commission rate increases once quota is exceeded. For example, 8% up to quota, 12% between 100% and 130% of quota, and 15% above 130%. This structure is one of the most effective ways to retain high-performing sellers.
Gross profit (margin)-based commission
Commission is calculated not on revenue but on the gross profit of the sale. It is ideal for distribution, wholesale or project-based businesses where discounts directly affect profit. When reps give a discount, they see their own earnings drop too.
Commission only
A fully performance-based model with no base salary. Outside of dealer networks, freelance sales agents or very short-cycle transactions, it is rarely sustainable in B2B. It makes it harder to find qualified candidates and encourages short-term thinking.
Team bonus
A shared bonus pool tied to the team reaching its overall target, in addition to individual commission. It works well as a complement to the individual plan in structures that require collaboration, where pre-sales support and account management are intertwined.
Practical tip: For SMEs building a structured plan for the first time, the combination of "base salary + quota-based commission + above-quota accelerator" is both easy to understand and a fair starting point.
How do you set the fixed-to-variable pay ratio?
The backbone of a commission plan is the concept of on-target earnings (OTE). OTE is the total gross pay a rep earns in a year upon reaching 100% of quota. This amount is split into fixed and variable components. This split is called the "pay mix."
As a general guide, typical role-based ratios are:
- SDR / BDR (role that generates leads and books meetings): 70% fixed – 30% variable
- Account Executive (role that closes deals): between 50% fixed – 50% variable and 60% fixed – 40% variable
- Account manager / customer success (role that grows existing customers): 70-80% fixed – 20-30% variable
- Sales manager: 60-70% fixed – 30-40% variable (tied to team performance)
When setting the ratio, ask yourself: How big is the rep's individual impact on whether the sale happens? In a setup where your marketing team delivers warm leads and your brand awareness is strong, it makes sense to keep the variable share low. Where reps create opportunities from scratch through cold calling, the variable share should be higher.
The sales cycle is also decisive. In enterprise sales averaging 6-9 months, keeping the variable share very high means the rep lives on low income for months. That, in turn, increases team turnover.
Building a commission plan step by step
1. Clarify company goals
Before you start on the plan, write down your commercial priority for the next 12 months. Is it winning new customers, cross-selling to existing ones, pushing a specific product line, or improving profitability? Your commission plan should support no more than 2-3 goals at a time. A plan that rewards five different metrics doesn't truly reward any of them.
2. Define roles
Document each role's responsibility in the sales process. If the SDR's job is to generate qualified meetings, the AE's job is to close deals, and the account manager's job is renewals and growth, each should be rewarded on a different metric. This step moves much faster if role definitions and sales stages are already documented in a B2B sales playbook.
3. Set OTE and the pay mix
Research market pay for similar roles in your industry and city. Then use the ratios above to split out the fixed and variable amounts.
4. Calculate the quota
Use two approaches together when setting quotas:
- Top-down: Divide the company's annual revenue target by the number of reps.
- Bottom-up: Calculate from a rep's realistic activity capacity (monthly meetings, conversion rate, average deal size).
If there is a large gap between the two figures, either the company target is unrealistic or additional resources (new reps, marketing support, lead generation) are needed.
As a common rule of thumb, an AE's annual quota is between 4 and 6 times their OTE. For high-margin software products, this multiple can go up to 5-8; for low-margin products, the quota should be defined on gross profit rather than revenue.
5. Set the commission rate and tiers
The base commission rate is found with a simple formula:
Commission rate = Annual variable pay ÷ Annual quota
Then define the tiers: at what point below quota does commission start (the threshold), and which accelerators kick in above quota?
6. Write the payment rules
- Is commission earned at invoicing or at collection?
- Are payments made monthly or quarterly?
- What happens if the customer cancels the contract within the first few months (clawback)?
- How is commission split on deals touched by more than one rep?
- What happens to commission on uncollected sales if the rep leaves the company?
7. Model and test the plan
Before rolling out the plan, simulate it using last year's actual sales data. What would each rep have earned under this plan? What percentage of revenue would total commission cost have been? Is the gap between top and bottom performers reasonable?
8. Put it in writing and get it signed
The plan should be documented in plain language that reps can understand, with sample calculations, and handed over against signature. In Turkey, bonuses are included in payroll and are subject to income tax and social security (SGK) contributions. It is important to consult your financial advisor and employment law counsel on the plan's alignment with employment contracts and its tax implications.
Sample calculation: A commission plan for an Account Executive
To make this concrete, let's work through a fictional software SME. The figures are only meant to illustrate the method.
Assumptions:
- Annual OTE for the AE: 1,200,000 TL
- Pay mix: 50% fixed – 50% variable
- Annual base salary: 600,000 TL
- Annual target variable pay: 600,000 TL
- Annual quota: 6,000,000 TL in new sales revenue (5 times OTE)
Base commission rate: 600,000 ÷ 6,000,000 = 10%
Tier structure:
- 0-50% of quota: no commission (threshold)
- 50-100% of quota: 10%
- 100-130% of quota: 15% (1.5x accelerator)
- Above 130% of quota: 20% (2x accelerator)
When a threshold is applied, no commission is paid on sales below it, so the rate for the 50-100% band must be recalculated for a rep who hits quota to receive their target variable pay: 600,000 ÷ 3,000,000 = 20%. The tiers then become:
- 50-100%: 20%
- 100-130%: 30%
- Above 130%: 40%
Scenario A – The rep reached 80% of quota (4,800,000 TL): Sales above threshold: 4,800,000 – 3,000,000 = 1,800,000 TL Commission: 1,800,000 × 20% = 360,000 TL Total annual earnings: 960,000 TL
Scenario B – The rep reached 120% of quota (7,200,000 TL): 50-100%: 3,000,000 × 20% = 600,000 TL 100-120%: 1,200,000 × 30% = 360,000 TL Commission: 960,000 TL Total annual earnings: 1,560,000 TL
This example shows how thresholds and accelerators work together: the cost of underperformance stays limited for the company, while above-quota performance is strongly rewarded. In Scenario B, every additional lira the rep generates comes with high profitability, since the company's fixed costs are already covered. That's why the extra commission paid through accelerators usually more than pays for itself.
If you don't want to use a threshold, you can go with the simple 10% rate. Simplicity has value too, especially for teams building a plan for the first time.
How should plans differ for SDRs, AEs and account managers?
SDR / BDR
SDRs don't have authority to close deals, so revenue-based commission isn't fair to them. Instead, the following metrics are used:
- Number of qualified meetings held (not just booked, but accepted by the AE)
- Pipeline value generated from these meetings
- As a small share, closed deals from opportunities they sourced
For example, if the monthly target is 15 qualified meetings and monthly variable pay is 15,000 TL, you could pay 1,000 TL per meeting, raising it to 1,300 TL for each meeting above target. To protect meeting quality, a rule that "meetings not approved by the AE don't count" is a must. For companies considering outsourcing outbound rather than building it in-house, SAAS Corner's B2B SaaS-focused outbound sales and lead generation service is one way to turn SDR costs and commission complexity into a fixed structure.
Account Executive
AEs are rewarded on new sales revenue (or annual recurring revenue). In software companies, it should be clearly stated whether commission is calculated on first-year contract value or total contract value. For multi-year contracts, a common approach is to apply the full rate in the first year and a lower rate in subsequent years.
To keep discounts from spiraling, it's effective to tie commission to pricing discipline, for example, by lowering the commission rate on sales below a certain percentage of list price. If your pricing architecture is value-based, your commission rules shouldn't undermine that logic; our guide on the value-based B2B SaaS pricing model helps you think through pricing and incentive structure together.
Account management and customer success
The key metrics for these roles are net revenue retention, renewal rate and expansion (upsell/cross-sell) revenue. Assigning a lower rate to renewals and a higher rate to expansion steers reps toward growing existing customers.
How do you set a realistic quota?
The most common mistake in quota setting is adding an arbitrary percentage to last year's figure. A sounder approach follows these steps:
- Analyze historical data: Average sales per rep, average deal size, conversion rates and sales cycle length over the last 12-24 months.
- Run a capacity calculation: How many qualified opportunities can a rep work per month? For example, with 10 new opportunities per month, a 25% win rate and an average deal size of 200,000 TL, annual capacity is: 10 × 12 × 0.25 × 200,000 = 6,000,000 TL.
- Factor in ramp time: A new rep shouldn't start with a full quota in month one. For example: 0% in month one, 25% in month two, 50% in month three, 75% in month four, and 100% from month five onward.
- Account for seasonality: Instead of dividing the annual quota by 12, spread it across months or quarters based on the seasonal distribution in historical data.
- Aim for 60-70% of reps to hit quota: If very few on the team hit quota, the quota is unrealistic; if almost everyone exceeds it comfortably, the quota is too low.
Data quality is everything in quota setting. To strengthen your forecasts, AI-powered sales forecasting methods can help you produce far more accurate capacity projections from historical pipeline data.
TL quotas in an inflationary environment
During periods of high inflation, an annual TL-based quota can lose its meaning in the second half of the year. As prices rise, reps easily exceed quota with the same number of customers, and the company pays high accelerators without any real growth. There are several ways to manage this:
- Setting quotas quarterly instead of annually and updating them each quarter
- For products priced in foreign currency, defining the quota in the same currency
- Using metrics less affected by inflation, such as customer count, unit volume or gross profit, instead of revenue
Whichever method you choose, the update rule must be set in writing at the start of the year. Raising quotas unilaterally mid-year is one of the fastest ways to lose the team's trust.
When should commission be paid: at invoicing or at collection?
A significant share of B2B sales in Turkey are made on payment terms. That makes the point at which commission is earned a critical decision:
- Payment at contract signing: The most motivating option for the rep, the riskiest for the company.
- Payment at invoicing: A middle ground, but the risk of uncollectible receivables stays with the company.
- Payment at collection: The safest option for cash flow. It encourages reps to pay attention to customer quality and payment terms.
For many SMEs, a balanced solution is to pay part of the commission (e.g., 50%) at contract signing and the rest at collection. In subscription models, a clawback clause should be added so that commission is recovered if the customer cancels within the first 3-6 months.
What are the most common mistakes in commission plans?
- Excessive complexity: If reps can't work out their commission in their head in 30 seconds, the plan is too complex.
- Capping commission: A cap tells top performers "that's enough." If you're concerned about high earnings, use decelerating rates or a special approval mechanism for very large deals instead of a cap.
- Changing rules mid-year: Plan changes should only be made at the start of a period and announced in advance.
- Rewarding revenue alone: A plan that ignores profitability, collections and customer quality produces short-term growth and long-term problems.
- Leaving territory and account assignments unclear: The "whose customer is this?" debate is the most common source of conflict within teams. Account ownership rules should be part of the plan.
- Delaying payments: Paying commission months after it was earned breaks the link between reward and behavior.
- Never analyzing plan results: Every quarter, check whether the plan is producing the expected behavior.
How can CRM and automation make commission tracking easier?
Calculating commission in Excel spreadsheets quickly becomes a source of errors and disputes once the team grows beyond 3-4 people. A reliable commission system depends on sales data coming from a single source, consistently.
To achieve this:
- Standardize deal fields in your CRM: Deal value, line items, discount rate, account owner, sourcing SDR, close date and collection status should be required fields.
- Map deal stages to commission rules: The "Won" stage and the "Collected" status should be tracked separately.
- Give reps their own dashboards: Every rep should be able to see in real time how close they are to quota and their estimated commission. This transparency alone boosts motivation and reduces disputes.
Your choice of CRM matters here; reporting flexibility and goal management features vary across platforms. If you're struggling with this decision, take a look at our HubSpot vs. Pipedrive decision guide for SMEs.
On the automation side, tools like n8n can be used to set up workflows such as:
- Sending a notification with the estimated commission amount to the rep and their manager when a deal is marked "Won"
- Automatically updating the deal in the CRM when a collection is recorded in the accounting software
- Preparing a per-rep commission summary at the end of each month and sending it to the finance team
- Automatically posting a celebration message in the team channel when 80% and 100% of quota are reached

How much should a commission plan cost the company?
When evaluating commission costs, look not at the commission rate in isolation but at total cost of sales as a percentage of revenue. This ratio varies widely by industry, margin and growth stage, but the calculation method is the same:
- Add up the annual base salaries of all sales staff.
- Add the total variable pay due at 100% quota attainment.
- Include employer social security contributions, benefits and sales tool costs.
- Divide this total by the team's total quota revenue.
The resulting ratio should be evaluated alongside your gross profit margin. A high-margin software company can allocate a larger share of revenue to cost of sales, while a low-margin distribution company needs to keep this ratio much tighter. The rule is simple: the gross profit from additional sales should be clearly higher than the commission paid on those sales. When modeling the plan, make sure this balance holds even in the most optimistic scenario (for example, the team achieving 150% of quota).
What should you do after the plan goes live?
A commission plan isn't a document you write once and forget. For a healthy cycle:
- Monthly: Share commission calculations on time and transparently.
- Quarterly: Review the distribution of quota attainment, average discount rates and plan cost. Is the plan producing unwanted behavior?
- Annually: Redesign the plan in line with changes in company strategy; share the new plan with the team at least a few weeks before the year begins and answer their questions.
When presenting the plan to the team, explain not just the numbers but the logic behind them. A rep who knows the answer to "Why do we pay on gross profit?" will act in the spirit of the plan.
Frequently asked questions
What is the best sales commission model for SMEs?
For most B2B SMEs, the most balanced model is a structure combining base salary plus quota-based commission and an above-quota accelerator. This model gives reps financial security while strongly rewarding high performance. For low-margin businesses, calculating commission on gross profit rather than revenue is recommended.
How is the sales commission rate calculated?
The base commission rate is found by dividing the rep's annual target variable pay by their annual quota. For example, with 600,000 TL in target variable pay and a 6,000,000 TL quota, the rate is 10%. If a threshold or accelerators are used, tier rates are recalculated based on this base rate.
Should commission be paid at the time of sale or at collection?
For B2B businesses that operate on payment terms, the safest method is to tie commission to collection, since it prevents paying commission on sales that can't be collected. To maintain motivation, a hybrid structure that pays part of the commission at contract signing and the rest at collection can also be used. In subscription models, a clawback clause should be added to protect against early cancellations.
How often should a commission plan be updated?
The plan's overall structure should be reviewed once a year, before the period begins. Quotas, however, can be updated quarterly, especially during periods of high inflation, provided the update rule was set in writing at the start of the year. Unilaterally changing the rules mid-year seriously damages team trust.
Conclusion
A good B2B sales commission plan comes not from complex formulas but from clear priorities. Decide what your company wants to achieve this year, choose the right metric for each role, base quotas on real data, write payment rules that protect profitability and cash flow, and document it all simply enough for your team to understand easily. Then use your CRM and automation infrastructure to make calculations transparent and error-free; measure the plan every quarter and improve it as needed.
Your commission plan is the clearest statement your sales strategy makes to your team.
