Agency Commission Model vs RetailerBoost: Who Actually Pays for the Ads?

When comparing Google Ads management options, the pricing model matters less than one fundamental question: who is paying for the advertising?

Most merchants assume that "commission on sales" means they only pay when results happen. But with traditional agencies, that is only half true. You still fund every click out of your own pocket. The commission model just changes how the agency calculates their management fee.

This post breaks down exactly how the typical agency commission model compares to what we do at RetailerBoost. No jargon, no spin - just a clear look at who pays for what, who carries the risk, and what that means for your business.

The Typical Agency Commission Model

Here is how most agencies structure commission-based pricing:

• You fund 100% of the ad spend directly to Google
• You pay the agency a commission (typically 10-20% of revenue or ad spend)
• You sign a contract (typically 3-12 months minimum)
• You may also pay a monthly retainer on top of the commission
• If campaigns do not convert, you lose the ad spend - the agency still gets paid

The commission structure sounds performance-based, but your money is at risk from day one. Every click costs you whether it converts or not. The agency earns their fee regardless of your profitability.

The RetailerBoost Model

Here is how we structure our pricing:

• We fund 100% of the ad spend with our own capital
• You pay a commission only on sales we generate (typically 8-15%)
• No contract - cancel anytime
• No retainer - zero monthly fees
• If campaigns do not convert, we lose money - you pay nothing

The difference is not subtle. We invest our money before you pay anything. If we cannot generate profitable sales, we absorb the loss. Your only cost is a percentage of revenue we actually deliver.

Side-by-Side Comparison

A Real Example

Let us say $10,000 is spent on Google Shopping ads for your products. Here is how the numbers work out depending on who pays for that ad spend:

With a Traditional Agency (You Fund Ad Spend)

• You pay Google $10,000 for clicks
• You pay the agency $1,500 monthly retainer
• Your total upfront cost: $11,500
• Scenario A: Ads generate $15,000 in sales (+ 10% commission = $1,500)
• Your total cost: $13,000. Your revenue: $15,000. Your profit: $2,000
• Scenario B: Ads generate $5,000 in sales (you still paid $11,500 upfront)
• Your total cost: $11,500+. Your revenue: $5,000. Your loss: $6,500+
• Scenario C: Ads generate $0 in sales (you still paid $11,500)
• Your total cost: $11,500. Your revenue: $0. Your loss: $11,500

With RetailerBoost (We Fund Ad Spend)

• We pay Google $10,000 for clicks on your behalf
• No retainer: $0
• Your total upfront cost: $0
• Scenario A: Ads generate $15,000 in sales (12% commission = $1,800)
• Your total cost: $1,800. Your revenue: $15,000. Your profit: $13,200
• Scenario B: Ads generate $5,000 in sales (12% commission = $600)
• Your total cost: $600. Your revenue: $5,000. Your profit: $4,400
• Scenario C: Ads generate $0 in sales (12% of $0 = $0)
• Your total cost: $0. Your revenue: $0. Your loss: $0. We absorb the $10,000 ad spend.

Same $10,000 ad spend. Same campaigns. Completely different risk profile. With a traditional agency, you can lose thousands even when ads underperform. With RetailerBoost, you profit on every sale we generate, and if we generate nothing, you pay nothing.

Why This Matters for Your Business

Cash Flow

With agencies, marketing is a cost that precedes revenue. You pay Google and the agency before knowing if campaigns will work. With RetailerBoost, you pay after receiving revenue from completed sales. Marketing becomes a cost that follows revenue, not one that drains cash flow hoping for results.

Risk

Agency relationships put 100% of the advertising risk on you. If their campaigns underperform, you lose money. They still collect fees. With RetailerBoost, we carry 100% of the advertising risk. If our campaigns underperform, we lose money. You pay nothing.

Predictability

Agency costs vary month to month based on ad spend, performance bonuses, and fluctuating results. With RetailerBoost, your ROI is fixed. At 12% commission, you always get 8.33X return on what you pay us. At 10%, you get 10X. The math never changes.

Commitment

Agencies typically require 3-12 month contracts to protect their investment in learning your account. We require nothing. Cancel anytime. If we are not delivering value, you should leave. Our job is to earn your business every month, not lock you into a contract.

When to Choose Each Model

Choose a Traditional Agency if...

• You need strategic consulting beyond campaign management
• You want control over specific campaigns, creative, and targeting
• You have budget for multi-channel coordination (Google, Meta, email, etc.)
• You are comfortable funding ad spend and accepting variable ROI

Choose RetailerBoost if...

• You want someone else to fund the ad spend entirely
• You need fixed, predictable ROI on customer acquisition
• Cash flow matters and you want to pay after revenue, not before
• You want zero financial risk if campaigns do not convert
• You prefer no contracts and the flexibility to cancel anytime
• You sell physical products via Google Shopping

The Bottom Line

The critical difference between agency commission models and RetailerBoost is not the percentage or the fee structure. It is who pays for the advertising.

With agencies, you fund the ads. You carry the risk. You pay upfront. You sign contracts.

With RetailerBoost, we fund the ads. We carry the risk. You pay after. No contracts.

That is the difference that matters. Everything else is details.
