Variable Pay — The Plain Definition
The broader HR definition of variable pay includes stock options, profit sharing, and annual bonuses. None of those apply to a web agency SDR team. At web agency scale, variable pay means two things: commission on verified closes (the primary component) and performance bonuses for hitting specific thresholds (the secondary layer). Everything else in the general definition is enterprise complexity that does not map onto a 3-person cold calling team.
Fixed Pay vs Variable Pay for Web Agency SDRs — The Real Difference
The question most web agency owners ask when hiring their first SDR is not "what is variable pay" — it is "should I pay a salary or commission?" That question is asking the same thing in practical terms. Here is what the difference actually looks like month by month for the same SDR.
The agency owner's risk, not the SDR's
Shared incentive — both benefit from more closes
The fundamental alignment argument for variable pay: A fixed salary creates a situation where the agency bears all the output risk. An SDR on £1,500/month who closes 1 deal costs the agency £1,275 in payroll above what that SDR generated in commission equivalent. An SDR on 15% commission who closes 1 deal costs the agency exactly 15% of the deal they closed — and costs nothing if they close nothing. Variable pay turns payroll from a fixed cost into a variable cost that scales proportionally with revenue.
5 Reasons Fixed Pay Does Not Work for Web Agency SDR Teams
Fixed pay removes the financial incentive to close more
An SDR on a fixed salary earns the same whether they close 2 deals or 6 deals this month. The financial incentive for additional effort above the minimum required to keep the job is zero. Variable pay creates a financial reason to close every additional deal — because every additional verified close directly increases the SDR's monthly earnings.
Fixed pay makes payroll a fixed cost regardless of revenue
A quiet month — whether due to list quality, seasonal patterns, or SDR performance — costs the agency the same in payroll as a strong month. Variable pay means payroll scales with revenue. A quiet month with 2 closes generates 2 commission payments. A strong month with 8 closes generates 8 — but also 4x the revenue those closes brought in.
Fixed pay does not drive quality — it drives attendance
A fixed salary incentivises showing up and doing enough to keep the job. Variable pay incentivises producing verified closes. In a cold calling context where daily output varies significantly between SDRs doing the same number of hours, the difference between incentivising attendance and incentivising output is the difference between a mediocre team and a high-performing one.
Fixed pay has no upper bound on the agency's cost
A fixed salary is the agency's guaranteed minimum payroll cost. If the SDR underperforms, the agency still pays the salary. Variable pay has no guaranteed cost because it only fires on verified closes — and every close it pays on represents revenue the close itself generated. An SDR on commission can never cost the agency more than they earn in commission equivalent.
Fixed pay undermines the leaderboard's motivational power
A live leaderboard showing each SDR's commission earned in real time is the most effective motivational tool for a web agency calling team. That effect requires commission amounts that are both real and meaningful — large enough to create competitive motivation. Fixed salary SDRs have no commission to show on the leaderboard. Variable pay SDRs see their earnings update with every verified close, during the same session — which is why variable pay and live leaderboards are always used together.
Types of Variable Pay That Apply to Web Agency SDR Teams
Indeed's article lists eight types of variable pay including stock options, profit sharing, and spot bonuses. For a web agency cold outreach team, the relevant types are two — everything else is enterprise compensation design that does not apply at this scale.
How to Set Up Variable Pay for a Web Agency SDR Team
Choose flat percentage or tiered commission
Flat percentage (e.g. 15% on every verified close) is simpler to explain and administer. Tiered commission (e.g. 10% under £1,000 / 15% at £1,500–£2,500 / 18% above £2,500) creates a specific financial incentive for SDRs to push for premium packages. For single-niche campaigns with consistent deal values, start flat. For multi-niche campaigns or agencies wanting to incentivise premium conversations, use tiered.
Set the rate based on your actual margin — not what seems generous
Your commission rate must come from your project margin, not from what feels fair. If your net margin on a £1,500 plumber website is 35% (£525), paying 15% commission (£225) leaves you with 20% net (£300). That is sustainable. Paying 25% commission (£375) leaves 10% net — too thin at volume. Calculate from actual margin before setting any rate.
Define exactly what "close" means before any SDR calls
Write this into the commission plan: a qualifying close requires both (1) the SDR logs it in the pipeline creating a Pending Verification status, AND (2) the agency owner explicitly approves it. Commission does not fire on verbal agreements, email confirmations, or SDR self-reporting alone. Owner verification is the gate. Both parties sign the plan before the first call.
Add the weekly bonus threshold for volume consistency
A flat bonus for 3+ verified closes in a calendar week (typically £100–£200) addresses the volume consistency dimension that percentage commission alone does not specifically reward. It creates a weekly goal independent of deal value — an SDR who closes 3 lower-value cleaning deals earns the same weekly bonus as one closing 3 high-value roofer deals. Combine with the tiered rate to incentivise both volume and value simultaneously.
Make commission visible in real time — not at month end
The motivational effect of variable pay is directly proportional to how quickly the SDR sees the reward after the effort that generated it. Month-end commission payment with month-end statement visibility wastes the short feedback loop advantage of web agency cold calling. A live leaderboard that updates commission earned immediately after each verified close delivers the full motivational effect during the session — not 30 days later.
What Variable Pay Looks Like in Practice — A Full Month Example
Here is a complete monthly variable pay calculation for one SDR on a mixed home services campaign using a tiered commission structure with a weekly bonus.
| Close Date | Business | Deal Value | Commission Rate | Commission Earned | Weekly Bonus |
|---|---|---|---|---|---|
| Tue 7 Apr | Reynolds Plumbing Leeds | £2,400 | 15% | £360 | — |
| Thu 9 Apr | Bright Spark Electricals | £1,600 | 12% | £192 | — |
| Fri 10 Apr | City Clean Manchester | £950 | 10% | £95 | — |
| — Week 1 Bonus | 3 verified closes in week 1 (Mon 7 – Sun 13 Apr) | — | £150 | ||
| Wed 15 Apr | Apex Roofing Bradford | £3,200 | 18% | £576 | — |
| Fri 17 Apr | GreenBright Gardens | £1,100 | 12% | £132 | — |
| Tue 22 Apr | FastKey Locksmiths | £750 | 10% | £75 | — |
| Thu 24 Apr | ProPlumb Sheffield | £1,900 | 15% | £285 | — |
| Monthly Total — 7 verified closes + 1 weekly bonus | £1,715 commission + £150 bonus = £1,865 | ||||
The tiered structure in action: the Apex Roofing close at £3,200 earned £576 at 18% — the highest single commission of the month. If the structure had been flat at 15%, Apex would have earned £480 — £96 less. The SDR who pushed the roofer conversation to the premium package earned an extra £96 on that single close. That is the amplified upside of tiered variable pay made concrete in one real close.
Common Variable Pay Mistakes Web Agencies Make
The most expensive variable pay mistake: Starting an SDR without a written commission plan. The moment an SDR closes their first deal, both parties have an interpretation of what they will be paid. Those interpretations are often different. A written commission plan signed by both parties before the first call is the only way to ensure those interpretations are the same. Writing it after the first close to resolve a dispute is too late — that dispute is already in progress.
