The traditional agency model is currently caught in what I call The Execution Trap. For decades, agencies and consultants have lived by a simple, if exhausting, math: more revenue requires more heads, and more heads require more management. But as AI begins to handle the high-volume execution tasks—copywriting, initial design mocks, data cleaning, and basic scheduling—the billable hour is losing its grip. To survive, smart firms are pivoting toward 'Operations-as-a-Service' (OaaS), a model where you don't just provide the output; you architect the system. This shift allows you to leverage the best SaaS affiliate programs to create a layer of recurring wealth that persists long after the initial implementation project ends.
I’ve watched hundreds of agencies struggle with the 'Agency Tax'—that invisible margin eater where manual processes steal the profit from every new contract. The OaaS pivot isn't just about efficiency; it's about changing your position in the value chain. You stop being a line item for 'labor' and start being the architect of 'results.'

We are witnessing the commoditization of the output. If a client can use an AI tool to generate a 1,000-word blog post or a functional piece of code in thirty seconds, they will eventually stop paying an agency £500 for it. They might pay for the strategy behind the post, but the execution itself is trending toward zero cost.
This is where most agencies panic. They try to 'add more value' by doing more manual work, which only accelerates their burn. The alternative is to own the stack. When you recommend, implement, and optimize the AI tools that run a client's business, you transition from a vendor to a partner.
Naming the Strategy: The Stack Stewardship Model
I call this The Stack Stewardship Model. In this framework, the agency’s role is to curate a bespoke selection of AI tools—an 'AI Stack'—that replaces or augments a client’s internal functions.
You aren't just selling your time anymore; you are selling a curated ecosystem. This ecosystem requires ongoing 'stewardship' to ensure the AI agents are prompted correctly, the data flows are clean, and the automations aren't breaking. This creates two distinct revenue streams:
- The Implementation Fee: A high-value, one-off project to audit the client's current costs and build their AI operations.
- The Recurring Referral Layer: By integrating the best SaaS affiliate programs into your recommendations, you earn a percentage of the software spend your clients are already prepared to commit to.
Why Most 'Affiliate' Strategies Fail
Most consultants treat affiliate marketing as a side hustle—dropping links in a PDF and hoping for a kickback. This is a mistake. To build real wealth, your referral revenue must be a byproduct of your Commercial Insight.
When I look at the costs of a traditional marketing agency, the overhead is usually dominated by junior-level execution staff. By shifting a client's budget away from human labor and toward high-leverage AI tools, you are actually saving them money while increasing your own margin.
Your recommendation carries weight because it is backed by a business case. If you show a client how an AI tool replaces a £3,000/month service for £30/month, they won't care that you're earning a 20% commission on that £30. They care about the £2,970 they just saved. This is why you should focus on partner programs that offer lifetime recurring commissions—these are the real gems in the world of SaaS partnerships.
How to Select the Best SaaS Affiliate Programs for OaaS
Not all programs are created equal. As a strategist, you need to filter for three things: Utility, Stickiness, and Incentive.
1. Utility: Does it solve a core business problem?
Don't recommend 'shiny' tools. Recommend tools that handle fundamental business functions: CRM, automated outreach, AI-driven accounting, or customer service bots. The more 'boring' the function, the more essential the tool.
2. Stickiness: How hard is it to switch?
Tools that hold data (CRMs) or run core processes (Automation platforms) have high switching costs. This ensures your recurring revenue stays stable for years, not months.
3. Incentive: Does the partner program reward the relationship?
Look for programs that offer tiered rewards. For example, our Penny Partner Program is designed specifically for consultants who want to guide their clients through the AI transition. We don't just want a link click; we want to support you as the trusted advisor.
The 90/10 Rule of AI Implementation
A common pattern I see across industries is the 90/10 Rule: AI can typically handle 90% of a specific operational function (like lead qualification or initial customer support). The remaining 10% still requires human oversight—the 'steward.'
Your agency should be that 10%. You provide the high-level strategy and the monthly optimization. The 90% is handled by the tools you've recommended. This allows you to manage 10x more clients with the same headcount. You aren't scaling people; you're scaling systems.
Moving from Consultant to Architect
If you're currently billing by the hour, the transition can feel daunting. You might worry that by making a client's business 'too efficient' with AI, you'll work yourself out of a job.
Actually, the opposite is true. When you compare the value of Penny vs. a traditional business consultant, the differentiator is the ability to produce measurable ROI quickly. A consultant who spends six months writing a report is a cost center. An architect who implements an automated savings engine in six weeks is a profit center.
By owning the 'Operations-as-a-Service' layer, you become indispensable. You are the person who knows how the entire machine works. If the client stops paying for your stewardship, they risk the machine breaking.
Your Step-by-Step OaaS Roadmap
- Audit Your Current Deliverables: Which of your agency’s services are now 80-90% automatable?
- Build Your 'Certified Stack': Select 3-5 core AI tools that solve these problems. Apply for their partner programs. These should be your go-to recommendations—the 'best SaaS affiliate programs' for your specific niche.
- Productize the Implementation: Stop selling 'consulting.' Start selling an 'AI Ops Setup' for a flat, high-value fee.
- The Stewardship Retainer: Offer a low-maintenance monthly retainer to oversee the stack, update prompts, and monitor the AI’s performance.
- Track the Savings: Use the savings you generate for your clients as your primary marketing case study.
The Window is Closing
The gap between what AI can do and what businesses are doing is currently a canyon. This canyon is your opportunity. But it won't stay open forever. As businesses become more AI-literate, they will start building these stacks themselves.
The agencies that win over the next three years will be those that plant their flag as 'Stack Stewards' now. Don't just be another person selling AI services. Be the person who builds the infrastructure that makes those services possible.
