The recent boom of the e-commerce industry means that we have an increasing number of specialised agencies popping up on the market, like mushroom after the rain, offering dedicated services specifically targeted at companies selling online. Find out, which companies offer support for e-commerces and how they can help you.

There are a number of challenges associated with the development of an e-commerce business, most of which can be solved in two ways. Firstly, you can hire new people, expand your in-house team, and create new departments. The second option is to take advantage of external companies that specialise in the relevant areas. Deciding on which solution is the most suitable for online shop owners depends on a number of factors and specific company needs. However, the latter is increasingly proving to be the more cost-effective, faster and efficient way.

What companies can assist in the development of e-commerce?

More importantly, there are obstacles that are practically impossible to work around using only in-house resources or would involve enormous costs, something the company is not prepared to do.

In this article, we will profoundly cover the areas of e-commerce in which external agencies can provide their assistance as well as list some examples of specific companies that specialise in these areas.

Agency or in-house team?

Before we move on to a list of agencies that can help with boost your e-commerce development, let’s take a moment to address this important dilemma that business owners and managers often have to face. When the need for further development arises, such as building an online shop’s SEO or assistance in entering a foreign marketplace, this question is usually the first to pop up. As a rule, there is no one-size-fits-all answer, but market trends show that, thanks to their expertise, agencies are increasingly becoming that optimal solution. What is the reason behind this?

There are two key advantages.

1. The agency’s extensive knowledge and experience as well as a track record of methods proven over many projects

Even the most experienced specialists have typically worked for only a handful of companies. On the other hand, specialised agencies are able to offer a ready-made, proven process that is often based on years of cooperation with companies from a similar industry. In addition, they offer knowledge, which is accumulated from a number of people who have worked on a variety of projects and know how to seamlessly implement the same methods in a new environment.

2. Lower cost

The cost of employing an experienced person will almost always be higher compared to an agency’s monthly invoice, not to mention the skyrocketing cost of recruitment and the increasingly competitive employment market. Moreover, let’s not forget the additional costs associated with employee onboarding and retention.

The areas in which external companies are able to support e-commerce businesses

As mentioned, we have divided the list of companies according to categories:

  1. Launching and maintaining online sales on marketplace platforms – companies specialising in selling on platforms such as Amazon, eBay, Allegro, Kaufland.de, Zalando, Cdiscount, etc. They help implement and optimise the offering on marketplaces.
  2. Fulfillment – agencies that help with the completion and dispatch of customer orders. Such companies often offer storage space or act as intermediaries in the process of finding optimal solutions in many countries. The services of such companies can prove extremely beneficial when venturing into foreign markets.
  3. Customer service – companies that help with customer service, including foreign sales and with the support of native speakers.
  4. Translation – same as above, companies providing assistance in translating, for example, product and category descriptions when branching out into foreign markets.
  5. SEO – companies offering all sorts of SEO-related services, which are essential for online shops aiming to base their sales on organic traffic.
  6. Legal support – companies offering legal services specialising in e-commerce.
  7. Tax support – companies offering services related to VAT registration and settlement in foreign markets (the so-called VAT compliance service).
  8. Accounting – companies providing accounting services for e-commerce, including for online sales across multiple marketplaces.
  9. Customer experience – companies specialising in analysing user behaviour and creating user-friendly and effective shopping experiences.

We would like to emphasise that in this article we will primarily focus on companies offering dedicated services for e-commerce. We have also written a separate blog article on tools offering e-commerce support services, most of which are based on the SaaS (Software as a Service) model.

So without further ado, let us turn to specific examples of companies falling under each of these categories.

  • the shop’s development stage
  • the company’s organisational culture
  • the number of markets, we operate on
  • the capabilities of our in-house team
  • the situation on the market
  • company’s costs

Each time, it is worth taking a hard look at the company’s current challenges and identify which ones are most in need of external support and should be addressed as soon as possible.
