Marketplace growth: Should you hire an agency, recruit in-house, or go it alone?

As the founder of a marketplace agency, it would be incredibly easy for me to tell you to outsource everything to professionals like us right away. After all, we live and breathe this industry, and we know exactly how to drive sales. But the truth is, an agency isn’t always the right fit. Depending on your current business stage, available resources, and long-term goals, jumping into an agency partnership too soon can backfire – especially if you haven’t nailed your product-market fit or ironed out your logistics infrastructure.

On the flip side, trying to handle everything single-handedly can quickly turn into an expensive, time-consuming lesson. Similarly, bringing on your first full-time hire without deep marketplace expertise carries its own set of risks. The key to success lies in matching your operational strategy to your company’s actual growth stage. In this guide, we will break down exactly when to partner with an agency, when to build an in-house team, and when it makes more sense to go it alone.

Weighing up the options: Which path is right for you?

Every path has its advantages and drawbacks. Ultimately, your choice should align with your budget, growth objectives, and existing e-commerce experience. Here is what you need to consider for each option.

When to choose an agency

An agency is usually your best bet if:

• You are brand new to online marketplaces: If you lack hands-on experience, an agency can guide you through the entire journey – from initial account setup and channel selection to launching ad campaigns and optimising your listings.
• You don’t have the time to manage daily operations: Running a business means spinning a lot of plates. Partnering with an agency allows you to delegate day-to-day marketplace management to dedicated specialists.
• You need fast, scalable results: Agencies come equipped with specialised knowledge, proven frameworks, and advanced software tools to get your products live and visible without the usual trial-and-error delays.
• You want to mitigate costly mistakes: Working with experts significantly reduces the risk of account suspensions, compliance issues, or wasted ad spend due to a lack of platform-specific expertise.
• Your internal resources are stretched thin: If you don’t have an established e-commerce department or an in-house expert, an agency instantly fills that gap as your strategic partner.

When to hire an in-house specialist

Recruiting an in-house specialist makes the most sense if:

• You want absolute control over your operations: Having an internal team member allows you to monitor progress in real time, pivot strategies instantly, and maintain direct oversight without any third-party intermediaries.
• You have the capital to invest in team building: Hiring requires substantial upfront and ongoing investments in salaries, training, and software licences. If your budget allows, building your own e-commerce division offers great long-term value.
• You want to build long-term internal expertise: Bringing a specialist in-house embeds vital institutional knowledge directly into your company culture, which pays off as you scale.
• You manage an extensive product catalogue: If you are dealing with thousands of SKUs, having an internal specialist focused solely on inventory health, listing optimisation, and performance analysis can often be more cost-effective than outsourcing.
• You need 100% dedicated focus: An internal employee lives and breathes your brand alone, allowing them to deeply align with your core values and company culture.

When to manage marketplace sales independently

Going it alone is a viable strategy if:

• You are a bootstrapped startup with a tight budget: If you are testing the waters and need to preserve capital, handling operations yourself eliminates agency fees or payroll commitments.
• You have the time and bandwidth to learn: If you are willing to invest hours into mastering marketplace algorithms, platform policies, advertising tools, and listing optimisation, you can absolutely kick-start the process on your own.
• You are selling a highly curated, small selection of products: Managing a small inventory is relatively straightforward and doesn’t initially require complex enterprise software or an entire team.
• You want to understand the mechanics from the ground up: Starting independently gives you invaluable, hands-on insight into how these channels work, making it much easier to manage agencies or employees down the line.
• You already have a background in e-commerce: If you have previously run an independent online store or sold on regional platforms like Allegro, adapting your skills to new marketplaces will be a much smoother ride.

Cost comparison: Agency vs. in-house vs. going it alone

Let’s talk numbers. The financial reality varies significantly depending on your target market and where you source your talent.

Recruiting a dedicated in-house specialist in the UK or Western Europe typically requires a monthly budget of around £3,500 to £5,500 gross (approx. €4,000 to €6,500), depending heavily on their seniority and location. In the CEE region, local salary expectations may be slightly lower, but regardless of geography, you must factor in additional overheads: employer National Insurance or tax contributions, recruitment fees, training, software subscriptions, and the onboarding time required to get them fully up to speed.

With an agency, costs are heavily influenced by the location of the team and their operational reach. Monthly retainers for European marketplace management generally start from around £1,200 to £2,500 (approx. €1,500 to €3,000) for core channels. However, this can easily scale up to several thousand pounds depending on the project scope, SKU complexity, and the number of international platforms (like Amazon, eMAG, Kaufland, or Bol) being managed simultaneously.

If you choose to handle things independently, your primary investment is your own time and mental energy. While there is no direct upfront financial outlay for labour, going it alone can stifle your growth and increase the risk of making expensive mistakes that could have been avoided with expert guidance.

Summary

There is no one-size-fits-all answer here. The right choice hinges entirely on your current business lifecycle, financial resources, and ultimate growth targets.
