How AI agents are transforming the agency model and creating a new way to deliver marketing, operations, and growth services.

The Traditional Agency Model

For decades, e-commerce and marketing agencies have relied on monthly retainers to manage client stores and campaigns:

• Teams manually update products, run campaigns, and optimise sites.
• Agencies charge a fixed fee, regardless of workload efficiency or performance.
• Clients pay for human labour and hours, not always measurable outcomes.

While effective, this model has limitations:

• High cost for clients, especially small and medium-sized businesses
• Manual processes can be slow and error-prone
• Scaling services across multiple clients often requires hiring more staff

Enter AI Agents: Services Without Retainers

AI agents offer a new paradigm: Agents as Services (AaaS). Instead of paying for hours or retainers, clients can leverage autonomous digital workers to handle tasks continuously, efficiently, and reliably.

How It Works:

• AI agents integrate with e-commerce platforms like Shopify, BigCommerce, and Adobe Commerce.
• Agents automate repetitive workflows: product management, inventory tracking, marketing campaigns, and reporting.
• Performance is measurable and outcome-focused, rather than time-based.

Benefits Over Traditional Retainers

1. Cost Efficiency

• Clients pay for outcomes rather than human hours.
• AI agents operate 24/7 without additional staffing costs.

2. Scalability

• Agencies can manage multiple clients simultaneously using the same AI agent framework.
• Adding more products or campaigns requires minimal additional effort.

3. Consistency and Accuracy

• AI executes workflows with precision.
• No human error in product listings, promotions, or marketing campaigns.

4. Real-Time Optimisation

• AI agents adapt to changes instantly: adjusting pricing, updating stock, or optimising campaigns.
• Traditional retainers require human teams to respond manually, often with delays.

5. Outcome-Focused Services

• Success is measured by tangible metrics like sales, conversion rates, and traffic growth.
• Agencies can focus on strategy and creative input, while agents handle execution.

Real-World Example: Agencies Using AI as a Service

An agency managing multiple BigCommerce clients implemented VortexIQ AI agents:

• Agents automated product listings, pricing updates, and inventory management.
• Marketing campaigns, email sequences, and social ads were executed and optimised automatically.
• Reporting and dashboards were delivered in real-time to clients.

Results:

• Agency reduced manual work by 70%
• Clients saw a 30% increase in efficiency and measurable ROI improvements
• Agencies shifted to outcome-based pricing, eliminating traditional retainers

Why Agencies Should Embrace Agents as Services

1. Deliver More Value: Clients get automation, accuracy, and measurable outcomes.
2. Reduce Overhead: Less dependency on human labour and manual processes.
3. Scale Faster: Serve more clients without proportionally increasing staff.
4. Focus on Strategy: Human teams can concentrate on high-value, creative work.
5. Future-Proof: Agencies that adopt AaaS position themselves ahead of competitors.

Final Word

The future of agency services is Agents as Services. AI agents transform operations, marketing, and analytics into automated, outcome-focused workflows. Traditional retainers will become obsolete as agencies adopt AI-driven models, delivering better results faster, cheaper, and more efficiently.

The agencies that succeed will be the ones who embrace autonomous agents as their core service delivery model.
