Sales commissions are one of the strongest tools a leadership team has for steering how its reps behave. As a business grows, though, the way those payouts are designed, calculated and verified changes in ways that many founders fail to anticipate.
As explained in a recent Brainz Magazine analysis, commission problems grow with organisational complexity rather than with the number of salespeople alone. Drawing on patterns seen across hundreds of commercial teams, the piece describes four stages of commission maturity that growing companies pass through. Knowing which stage a business is in helps leaders spot weak points before they damage trust within the sales team or throw financial forecasts off course.
The first stage covers the earliest period, when a company has between one and five reps. Founders usually work out payouts themselves, often as a flat percentage of closed revenue. The appeal is obvious: every rep knows exactly what a signed deal will earn them, so the incentive is immediate and easy to act on. The weakness is less visible. A flat rate rewards every dollar the same way, so a heavily discounted one-year contract pays the same share as a high-margin multi-year agreement. The advice at this point is to invest in thoughtful plan design instead of software, tying compensation to margin, retention and unit economics before the team expands.
The second stage typically arrives once a company has ten to twenty-five reps. Responsibility for commissions moves to finance or operations, and plans start to include quotas, tiered accelerators, split deals, ramp periods and clawbacks. All of this usually lives in a spreadsheet that grows more tangled with every new rule. The real cost appears when a rep can no longer estimate the commission on a deal still in the pipeline. At that point the plan stops shaping day-to-day decisions and turns into a payment that is only understood after the fact. The recommended remedy is clarity: a plan that cannot be explained on a single page with simple calculation rules has lost its strategic purpose to mechanics.
The third stage is where most founders get stuck, and headcount is rarely the trigger. Diversification causes it, whether through a broader product range, subsidiaries in other countries, multiple currencies or separate roles for SDRs, account executives and account managers. The warning signs are familiar. Closing out commissions stretches from hours into weeks, reps keep their own private records to check the official figures, and disputes become routine. Errors also cut unevenly: overpayments caused by broken formulas or later refunds tend to slip through unnoticed, while any underpayment is raised straight away and erodes morale. The underlying issue is that spreadsheets produce a monthly total per person and lose the deal-level logic and timeline behind it, which makes later audits or quarterly reviews extremely difficult. Adding more formula fixes cannot solve what is essentially a data and infrastructure problem.
The fourth stage replaces manual month-end work with automated, connected incentive management. Mature organisations separate compensation rules from fixed formulas so plans can change on set dates without rewriting past calculations. They connect commission systems directly to CRM, billing and ERP tools so contract changes and payment statuses update automatically. They also keep a permanent, deal-by-deal audit record, which supports ASC 606 requirements to capitalise incremental customer acquisition costs at the contract level. For leaders unsure where they stand, the article suggests a simple test. Choose a closed quarter, select three reps at random and ask finance to show exactly how each payout was calculated, including the rule versions and adjustments in force at the time. If that takes days of spreadsheet detective work instead of minutes, the company is in stage three, and fixing the structure early will cost far less than rebuilding the sales team’s trust later.
