For ecommerce brands looking to grow their affiliate channel, one of the most important decisions is whether to manage the programme internally or appoint a specialist affiliate marketing agency.
Both approaches can work.
An in-house affiliate manager offers direct integration with the business, closer day-to-day access to internal teams and greater control over priorities.
A specialist agency brings established publisher relationships, cross-sector experience, dedicated resources and access to expertise that may be difficult to build internally.
The right choice depends on your brand’s size, commercial objectives, existing programme performance and the resources available.
However, the decision shouldn’t simply come down to whether an agency retainer is cheaper than hiring an employee.
The more important question is:
Which management model will generate the greatest additional commercial value for your business?
In this guide, we’ll compare the costs, advantages and limitations of both approaches, explain when each makes sense and explore why a hybrid model is increasingly relevant for ambitious ecommerce brands.
An affiliate marketing agency manages and develops partnerships between a brand and third-party publishers, creators, content platforms and other commercial partners.
A specialist agency’s responsibilities typically include:
The objective should be to grow the programme through more effective partnerships, rather than simply administer the affiliate network.
At Conversion Digital, our approach places particular emphasis on proactive recruitment, commercially aligned publisher relationships and measuring the value generated beyond last-click revenue.
An in-house affiliate manager is employed directly by the brand to oversee its affiliate programme.
The responsibilities can be similar to those of an agency, including publisher communication, recruitment, campaign planning and reporting.
However, an internal manager typically has greater day-to-day access to the business.
They may work closely with:
This can be particularly valuable when affiliate marketing is closely integrated with wider trading and marketing operations.
The challenge is that one individual may be expected to manage every aspect of the programme.
From publisher recruitment and commercial negotiations to technical tracking, attribution, reporting and validation, affiliate management requires a broad combination of skills.
Finding one person with deep expertise across every area can be difficult.
| Consideration | Specialist affiliate agency | In-house affiliate manager |
|---|---|---|
| Publisher relationships | Existing relationships across multiple clients and sectors | Relationships developed around the employer’s programme |
| Expertise | Access to different specialists and wider market experience | Deep knowledge of one brand and its internal operations |
| Recruitment | Potential access to established prospecting processes and publisher contacts | Recruitment capacity depends on individual resources |
| Cost | Retainer, performance fee or hybrid arrangement | Salary, employer costs, tools, recruitment and training |
| Control | Requires agreed priorities and communication processes | Direct internal management |
| Scalability | Can increase resources through the agency, subject to scope | Additional capacity may require recruitment |
| Reporting | Can provide cross-programme experience and specialist analysis | Direct access to internal commercial data |
| Internal integration | Requires collaboration with existing teams | Usually more closely integrated |
| Continuity | Agency may provide wider team coverage | Greater dependency on individual employees |
Neither model automatically delivers stronger results.
The quality of the people, processes and commercial strategy matters more than the label.
Cost is often the starting point when deciding between agency management and an internal hire.
But brands need to compare the total cost of each model, not simply the headline monthly fee or salary.
Employing an affiliate manager involves more than salary.
Depending on the role and business, additional costs may include:
For illustration, consider a hypothetical affiliate manager earning £45,000 annually.
The total employment cost will exceed £45,000 once applicable employer contributions and other expenses are included.
The brand may also require external support for specialist areas such as tracking, analytics or technical integrations.
The exact cost depends on the employee’s circumstances, the business and current employment rules.
Agency pricing varies depending on programme complexity, geographic scope and required services.
Common commercial models include:
Fixed monthly retainer: An agreed management fee covering a defined scope of work.
Retainer plus performance fee: A base management fee combined with commission linked to agreed results.
Performance-led arrangements: Fees tied more directly to measurable commercial outcomes, subject to minimum commitments or other conditions.
Consultancy or project-based support: A defined audit, launch, recruitment project or strategic engagement.
An agency may provide access to multiple areas of expertise without requiring the brand to employ several specialists.
However, agency fees should not be considered in isolation.
Affiliate network charges, publisher commissions, tenancy budgets and other programme costs may still apply under either model.
The correct comparison is not simply:
Agency retainer vs employee salary.
It is:
Total management cost relative to the additional profitable value generated.
A lower-cost arrangement that produces little growth may be more expensive commercially than a higher-cost arrangement that develops a strong, profitable channel.
One of the biggest differences between agency and in-house management is access to publisher relationships.
A specialist affiliate agency may already work with a wide network of:
These relationships can help accelerate introductions and commercial discussions.
For example, an agency managing several fashion and lifestyle programmes may already understand which publishers regularly feature occasionwear, jewellery, beauty and accessories.
That knowledge can help identify relevant opportunities more efficiently.
However, existing contacts alone do not guarantee results.
Publishers still need a compelling reason to promote a brand.
Product relevance, commission, audience fit, brand positioning and commercial potential all influence whether a partnership becomes active.
A successful affiliate programme should not rely entirely on publishers applying through an affiliate network.
It requires identifying relevant partners and developing relationships.
That process should include:
Our guide to recruiting high-quality affiliates explains this process in greater detail.
For brands without dedicated recruitment resources, this is one area where specialist agency support can be particularly valuable.
An experienced in-house affiliate manager can develop a deep understanding of the brand.
They may know the product catalogue, promotional calendar, customer segments, margins and internal decision-making processes exceptionally well.
This can help them make commercially informed decisions quickly.
A specialist agency offers a different advantage.
By working across multiple programmes, an agency can develop insight into:
The agency may recognise patterns and opportunities that are less visible within one programme.
For example, a brand may believe its affiliate channel has reached its natural revenue ceiling.
An agency reviewing the programme might identify that most revenue comes from a small number of voucher and cashback partners, while editorial and creator partnerships remain underdeveloped.
The opportunity may be to improve the partner mix rather than simply increase existing promotional activity.
Our guide to growing an affiliate programme explores how this type of analysis can reveal new growth opportunities.
In-house management can offer important operational advantages.
An internal affiliate manager may attend trading meetings, coordinate directly with merchandising teams and respond quickly to changes in stock, promotions or commercial priorities.
They can also work closely with internal stakeholders without relying on external communication processes.
An agency relationship requires clear responsibilities and regular collaboration.
If the agency operates separately from the wider business, opportunities can be missed.
For example, an agency might recruit a relevant editorial publisher but receive product launch information too late to secure timely coverage.
Or an internal PR team might be developing a major campaign without involving the affiliate team.
These issues are avoidable.
A well-managed agency relationship should include:
The best results usually come when the agency operates as an extension of the brand’s marketing team rather than an isolated supplier.
One of the most important considerations is how performance will be measured.
Affiliate network dashboards are useful for tracking transactions, revenue, commission and publisher activity.
But attributed revenue is not necessarily the same as incremental revenue.
Imagine a programme reporting £100,000 in monthly affiliate sales.
If much of that revenue comes from customers who were already intending to purchase, the actual additional value may be considerably lower.
A strong management approach should investigate:
An in-house manager may benefit from direct access to internal customer and financial data.
An agency may contribute specialist analytical processes and experience across other programmes.
The strongest arrangement often combines both.
For a more detailed explanation, see our affiliate marketing incrementality guide.
Affiliate marketing increasingly overlaps with digital PR, influencer marketing and creator commerce.
Many publishers monetise product recommendations through affiliate links.
Creators may work through commission, product gifting or hybrid arrangements.
Editorial publications may offer a combination of earned coverage and commercial shopping opportunities.
Developing these relationships requires a different approach from managing traditional conversion-focused publishers.
A specialist agency with experience across editorial and creator partnerships can help brands identify relevant opportunities and structure appropriate commercial arrangements.
For example, a fashion brand might want to secure:
An internal affiliate manager can also develop these partnerships, particularly when supported by established PR and influencer teams.
The important factor is whether the business has the relationships, resources and expertise required.
Read our guide to affiliate marketing and digital PR for more on developing editorial publisher relationships.
The resources needed to manage an affiliate programme can change significantly as it develops.
A small programme with a limited number of active partners may be manageable by one internal employee.
A larger programme operating across multiple networks, markets and publisher categories can become more complex.
Growth may introduce additional requirements, including:
An agency may be able to provide additional resources without the brand needing to recruit a new employee for every specialist function.
However, the agency’s scope and pricing may need to expand accordingly.
For in-house teams, scaling may involve recruiting additional affiliate managers or specialist support.
Both approaches can work, but brands should consider future requirements rather than only current workload.
In-house management may be the strongest option when:
For larger ecommerce businesses, a dedicated internal affiliate team can be highly effective.
The challenge is ensuring the team has enough capacity to develop new opportunities rather than becoming consumed by administration.
Agency support may be particularly valuable when:
An agency can also be useful when a programme needs restructuring.
For example, a brand may have operated on the same commission model for several years without reviewing publisher contribution, customer acquisition or profitability.
An external audit can identify opportunities that have become difficult to recognise internally.
For some ecommerce brands, the best solution is not choosing between agency and in-house management.
It is combining them.
Under a hybrid model, the internal team retains ownership of the affiliate channel while a specialist agency supports defined areas.
This could involve:
In-house responsibilities
Agency responsibilities
The exact responsibilities should be agreed clearly.
For example, an ecommerce business might have an experienced internal affiliate manager but limited relationships with premium editorial publishers.
Rather than replacing that employee, the brand could appoint an agency specifically to develop editorial and creator commerce opportunities.
Alternatively, an agency could manage day-to-day programme delivery while the internal ecommerce director retains strategic oversight.
This approach can provide specialist capability while preserving internal control.
To evaluate the two options properly, brands should compare more than total attributed affiliate revenue.
A useful framework includes four areas.
Calculate the full cost of agency management or internal employment, including relevant tools, support and additional programme expenses.
Review validated revenue, contribution margin, acquisition costs and total channel profitability.
Assess whether affiliate activity is introducing new customers and influencing additional purchases rather than simply receiving attribution for existing demand.
Evaluate whether the programme is building new relationships, improving its publisher mix and creating future growth opportunities.
For example, an agency may generate stronger publisher recruitment in the first 90 days without immediately delivering the same level of attributed revenue as an established cashback partner.
Those recruitment activities should still be evaluated against clear activation and performance milestones.
The objective is to measure both short-term commercial outcomes and the development of a stronger channel.
If you appoint an agency, you should expect a clear plan.
The precise scope will vary, but a structured initial period might look like this.
Not every editorial or strategic partnership will deliver sales within 90 days.
However, the agency should be able to demonstrate meaningful progress, explain what has been achieved and identify the next actions.
Before appointing an agency, ask:
The answers should help establish whether the agency offers meaningful additional capability.

At Conversion Digital, we work with ecommerce brands to develop affiliate and partnership programmes focused on profitable growth.
Our approach combines:
We recognise that every brand has different requirements.
Some businesses need full affiliate programme management.
Others already have capable internal teams but require additional expertise, publisher relationships or specialist support.
The objective is to build the right management structure around the brand’s commercial goals.
Through our affiliate and partnership management services, we help ecommerce brands identify growth opportunities and develop partnerships capable of delivering measurable value.
It depends on the brand’s resources, programme complexity and objectives. An in-house manager offers closer internal integration, while a specialist agency can provide broader expertise, established publisher relationships and additional resources.
Pricing varies depending on scope, markets and programme complexity. Common arrangements include fixed monthly retainers, performance fees and hybrid models. Brands should compare total management costs and commercial outcomes rather than headline fees alone.
Yes. A hybrid arrangement can allow an internal team to retain strategic control while an agency supports recruitment, publisher development, specialist partnerships or programme optimisation.
Potential advantages include specialist expertise, publisher relationships, recruitment capacity, technical experience and flexible resources. Results depend on the agency’s capabilities and the agreed scope.
In-house management can make sense when the programme is sufficiently large, the business has access to experienced talent and close daily integration with internal teams is important.
Many specialist agencies work across platforms such as Awin, Rakuten, impact.com and other affiliate networks. The appropriate network depends on the brand’s requirements, publisher mix and target markets.
Evaluate validated revenue, profitability, customer acquisition, publisher recruitment, incremental contribution and the total cost of management. Attributed affiliate revenue alone is not a complete measure of agency value.
Choosing between in-house management and an affiliate agency is ultimately a decision about capability, resources and commercial value.
The right structure should give your brand the expertise and capacity to recruit better partners, optimise existing activity and generate more profitable revenue.
