Selling on Amazon yourself or using an agency – which to choose?

Last updated: 26.05.2026

Selling on Amazon may look simple only from the outside. In practice, it involves daily work on listings, advertising, content, catalogue, compliance, and performance analysis. That is why many companies reach a point where a specific question arises: manage sales in-house or outsource them to a specialised agency?

In-house selling on Amazon - when does it make sense?

Managing sales on your own can be a good option if your business has the people, processes, and time to manage the account on a regular basis. You need to constantly update listings, monitor prices and availability, optimise advertising, respond to technical issues, and ensure compliance with Amazon policies.

The challenge arises when operational tasks start to consume too much of the team's time. Instead of developing products, improving margins, or planning expansion, the company focuses on firefighting daily problems. At that point, Amazon can stop being a growth channel and become a source of chaos.

What are the benefits of working with an Amazon agency?

An agency takes over not just individual tasks, but the entire sales management process. It takes care of the catalogue, content, advertising campaigns, reporting, compliance, troubleshooting, and preparation for development in new markets.

The greatest value of such cooperation is that the company does not have to build everything from scratch. It benefits from the experience of a team that knows typical mistakes, has proven procedures, and can bridge strategy with daily operational work.

1. Time savings and relief for the team

Managing Amazon requires regularity. Listings need to be updated, campaigns analysed, cases opened, and the catalogue constantly organised. These tasks can take up hours of work each week.

An agency takes over the day-to-day management of the account, allowing the client's team to focus on what often has the greatest impact on the business: product, logistics, strategy, pricing, and margin. This is particularly important for companies that want to scale their sales but do not wish to expand their in-house team specifically to manage Amazon.

2. One team instead of several fragmented providers

Selling on Amazon requires multiple skills: strategy, advertising, design, copywriting, analytics, compliance, and account management. When each part is handled by a different provider, delays, inconsistencies, and communication errors are likely to happen.

An agency provides a single team responsible for the whole package. As a result, operations are consistent, decisions are faster, and the client does not have to coordinate multiple companies simultaneously. This is especially important when sales involve a larger catalogue, multiple categories, or several markets.

3. Catalogue organisation and better product presentation

Chaos in the catalogue can severely limit sales. Duplicate listings, incorrect categories, poorly linked variations, wrong attributes, or missing products make it harder for the customer to buy and weaken the visibility of the offer.

An agency organises the catalogue structure: parent-child variations, categories, attributes, EAN codes, duplicates, and listing merges. This is technical work, but its effect is very tangible: more stable listings, an easier choice for the customer, and fewer operational issues.

4. Content that helps sell

On Amazon, a product description is not an accessory. It is one of the most critical elements in the purchase decision. A customer needs to quickly understand what the product is, who it is for, and why they should choose it.

That is why well-prepared titles, bullet points, infographics, comparison tables, A+ content, and brand storytelling matter. Strong content answers the buyer's questions, showcases benefits, and reduces the risk of incorrect purchases. This impacts not only conversions but also the professional perception of the brand.

5. Profit-driven advertising

Ad campaigns on Amazon can drive sales growth, but without control, they can easily become a source of unnecessary costs. Simply launching ads is not enough. You need to analyse which campaigns work, which require optimisation, and where it makes sense to scale the budget.

An agency looks at advertising more broadly than just through the prism of spend. What matters is the cost of sales acquisition, ACoS, TACoS, the impact of campaigns on total sales, and the margin. The goal is not just to increase turnover, but to achieve growth that makes business sense.

6. Lower risk of suspensions and account issues

Amazon has its own rules that must be followed. Document errors, incorrect attributes, brand registration issues, policy violations, or improper seller practices can lead to suspensions and downtime.

An agency helps mitigate these risks. It ensures operations comply with Amazon's policies, supports with Brand Registry, intellectual property protection, requests to support, and technical troubleshooting. Not every case can be resolved immediately, but experience helps choose the right course of action faster.

7. Smoother expansion into new markets

Entering a new market is not just about translating descriptions. One must match categories, pricing, logistics, content, advertising, and formal requirements. Without a process, errors, delays, and unnecessary costs are easily incurred.

An agency helps prepare the expansion in an organised manner. This allows the business to enter new markets faster, avoid common issues, and manage operations across multiple countries simultaneously.

8. Decision-driving reporting

Good reporting is not about sending a table of results. A company needs to know what has changed, why it happened, and what steps should be taken next.

An agency presents data in context. It points out where to increase budget, which products to develop, what needs improvement, and where to reduce costs. Such a report is not merely a summary of the month. It is a decision-making tool.

Who represents the best fit for collaboration with an Amazon agency?

Working with an Amazon agency is particularly beneficial for companies that view this channel not as a one-off test, but as a component of long-term sales growth. This approach works especially well when a brand wants to enter Amazon in a structured way, expand sales across multiple markets, or better leverage the potential of its current account.

Agency vs. in-house sales - which one to choose?

In-house sales will work well if the company has a team that knows Amazon and can regularly manage the account. This is a good solution for brands that want to maintain complete control and are ready to invest time in learning and ongoing optimisation.

An agency will be a better choice if the company wants to organise sales faster, reduce the risk of errors, and develop Amazon as an important business channel. This is particularly relevant with a larger catalogue, international expansion, rising ad costs, or account issues.

The most important question is not, therefore: "Does every company need an agency?". A better question is: "Does our team today have the time, knowledge, and processes to grow Amazon effectively and profitably?".

Such support can be particularly valuable for private labels, manufacturers, and distributors. Private labels require consistent product presentation, recognition, and control over brand image. Manufacturers can use Amazon to sell without intermediaries and gain better control over their offerings. Distributors, on the other hand, often work with a broad catalogue that requires a solid structure, clean listings, and efficient product availability management.

An agency is also a good choice for companies planning international expansion. Selling on Amazon in Germany, France, Italy, Spain, the Netherlands, Poland, the United Kingdom, or the USA requires not only translating content but also adapting strategies to local market characteristics, regional buyer expectations, ads, logistics, and plateform requirements.

Such a collaboration makes the most sense when a company wants to develop Amazon consciously: with control over the catalogue, advertising, prices, stock, margin, and account health. In this model, the agency does not replace the client's business but acts as a partner that helps structure the process, reduce error risks, and build sales on solid foundations.

FAQ - selling on Amazon in-house or with an agency

Can sales on Amazon be managed in-house?

Yes. In-house selling is possible if the company has the right team, time, and knowledge. However, it is important to remember that Amazon requires regular work on the catalogue, advertising, content, compliance, and performance analysis.

When should you consider working with an Amazon agency?

When managing the account starts to take up too much time, ad results are unpredictable, the catalogue needs organizing, or the company wants to expand into more markets without operational chaos.

Does an agency take over the entirety of sales on Amazon?

An agency can take over full operational management, but a successful collaboration also requires client involvement. At the start, product data, images, information on variations, pricing, and availability are needed, among other things.

What is the greatest benefit of working with an agency?

The greatest benefit is access to the experience, processes, and a team of specialists. As a result, the company does not have to learn everything from scratch on its own and can develop sales faster.

Does an agency only help to increase sales?

No. Sales alone are not enough if profitability does not follow. Therefore, ad costs, Amazon fees, returns, logistics, pricing strategy, and margins are also crucial.

Does an agency assist with international expansion?

Yes. An agency helps prepare local listings, ads, pricing, logistics, and compliance with the specific market's requirements. This makes expansion more organised and less risky.

Can all issues with Amazon Support be resolved immediately?

No. Some matters take time and multiple steps of communication. However, the agency's experience helps better prepare cases, respond faster, and reduce sales downtime.
