# Agency vs in-house team: the right call for ecommerce

> For most ecommerce brands the right setup is hybrid: use an agency to get several specialties quickly, and keep an ecommerce lead inside who makes the decisions. An in-house team knows the product best, but its fixed cost and the knowledge lost when people leave are real risks. Always open ad accounts in the brand's name.

## Agency or in-house team: which should an ecommerce brand choose?

For most ecommerce brands the right answer is both, in sequence: start with an agency, then add a small in-house team that works alongside it. An agency is faster when you need several specialties at once (ads, tracking, SEO, creative) and the budget can't cover a hire for each. Product knowledge, goals and decisions should stay inside.

Framing it as "one or the other" usually leads to the wrong call. The useful question is which work belongs inside the brand and which is done better, and more cheaply, outside. Brands that hire before answering that tend to come back to the same question a few months later.

## What does an in-house marketing team really cost?

Salary is only the start. On top of it come payroll taxes and benefits. Hiring takes a few months, and a new person needs a few more to learn the account. Licences for creative, analytics and reporting tools, training, and the time a manager spends on that hire all belong in the calculation.

The biggest cost is the one you don't see: overloading a single person. There's a pattern we see often. A brand hires one "digital marketing specialist" and expects them to run Meta ads, Google Ads, SEO, email flows, social content and the GA4 setup at the same time. That person tries hard to keep up with everything and never goes deep on any of it. Six months later the brand concludes that "digital marketing doesn't work for us." The channel wasn't the problem. The structure was.

Then there's continuity risk. When the person who built the account leaves, the campaign logic, the testing history and some of the logins can leave with them.

## What are the pros and cons of working with an agency?

An agency's biggest strength is breadth. One contract gives you access to several people who know ads, measurement, creative and SEO. A good agency has seen the same problem in other accounts, so it usually finds the cause faster, whether that's a Meta campaign stuck in the learning phase or a gap between GA4 and ad platform sales. When someone is on holiday, your account isn't left without an owner.

The downsides are real too. An agency won't know your brand as well as you do, so you have to feed it product, stock and promotion calendar information. Communication can lag. With a weak agency, a smaller account can slip down the priority list. And the most serious risk: if your ad accounts were opened in the agency's name, leaving can mean losing your data and history.

If you want to understand agency pricing models (fixed fee, budget-based fee, performance-based models), our article on [digital marketing agency fees](/en/blog/digital-marketing-agency-fees) explains when each one makes sense.

## How do agency, in-house and freelancer compare?

| Criterion | In-house team | Agency | Freelancer |
|---|---|---|---|
| Speed to start | Slow, hiring and onboarding needed | Fast, team in place | Fast |
| Range of expertise | Limited by headcount | Broad, several specialists | Usually one area |
| Product and brand knowledge | Deep | As much as you share | As much as you share |
| Fixed cost | High, continues in quiet months | Contract-based, flexible | Low, per project |
| Risk when someone leaves | High | Low, the team takes over | High |
| Management load | High, hiring and development on you | Medium, goals and briefs on you | Medium to high |

A freelancer is a good fit for a single, well-defined job, such as a landing page design or a one-off SEO audit. Once several channels have to be managed together, coordinating three or four freelancers becomes a part-time job in itself.

## When does an in-house team make more sense?

Building inside pays off in a few situations. If creative needs a daily rhythm (dozens of new videos, product shoots and social posts every week), having the person who makes them inside the brand, next to the product, is a big advantage. If your ad spend and order volume justify someone running a channel full time, an in-house specialist makes sense. And if CRM and customer data are the core of your business, it's risky for that knowledge to live outside.

Even then, most brands keep getting outside help for work that needs deep specialist skills, such as tracking setup, technical SEO or launching a new channel.

## When does an agency make more sense?

An agency usually delivers more in these phases:

- You're opening a new channel (for example Google Shopping or TikTok ads for the first time) and want to cut the cost of trial and error.
- Your tracking is incomplete: the Pixel, Conversions API, GA4 and conversion tracking need to be set up correctly once.
- Revenue has been flat for a while and you need an outside view from someone who has seen many accounts.
- You need to get ready for a peak season like Black Friday quickly and have no time to hire.

## How do you set up a hybrid model?

The structure we recommend most is a few of the right people inside and a specialist agency outside. Build it in this order:

1. **Name an owner inside.** An ecommerce or marketing lead who manages the agency, sets goals and passes on product, stock and promotion plans. Without this person, even an experienced agency works blind.
2. **Keep account ownership with the brand.** Google Ads, your Meta business portfolio, GA4 and your store platform should be opened in the brand's name, with access granted to the agency. According to Google's help page, you can change someone's access level or remove it at any time.
3. **Write down who decides what.** Which decisions can the agency make alone, and which need your approval? Budget increases, new channels and pricing messages usually belong in the second group.
4. **Agree on one report and a weekly rhythm.** Focus on business metrics such as store revenue, new customers and contribution margin rather than dashboard ROAS.
5. **Review the setup every quarter.** Look at which work is growing inside and make your first in-house hire based on that.

## What should your first in-house hire be?

Our view is clear: your first hire usually shouldn't be an ads specialist. Ad management is the easiest expertise to buy from outside. The person most brands are missing is an ecommerce lead who understands operations and data and can manage an agency. Next comes a creative producer: someone who can hold the product and make new videos and images every week has a direct effect on ad performance.

## How do you stay in control when working with an agency?

A few technical details prevent most future problems. According to Google, agencies manage multiple client accounts through a manager account (MCC); a linked account keeps its own sign-in, and if you part ways, you simply remove the link. On Shopify, you never hand over the store owner's password: Shopify Partners use collaborator accounts with permissions you can limit. If an agency shows a partner badge, know what it means: Google requires an optimization score of about 70 across managed accounts, a set amount of ad spend over 90 days and at least half of the account strategists certified. If you share customer data, define the data processor relationship in your contract under your local privacy law (in Türkiye, KVKK).

Deciding which work stays inside and how to bring in outside help is the first step of our [growth strategy work](/en/services/growth-strategy).

Pricing is shared in writing after the audit.

## Key takeaways

- For most ecommerce brands the right setup is hybrid: an owner who decides inside, a specialist agency outside.
- An in-house team costs more than salary: hiring time, tools, management time and knowledge lost when someone leaves.
- An agency brings breadth and speed; you still have to supply brand and product knowledge.
- Ad accounts, GA4 and your store platform should always be in the brand's name, with only access given to the agency.
- Your first in-house hire is usually an ecommerce lead or a creative producer, not an ads specialist.

## FAQ

### Should a small ecommerce brand start with an agency or a hire?

If you need ads, tracking and creative at the same time and the budget can't cover a specialist for each, starting with an agency is usually faster. Expecting one in-house generalist to master every channel is a common mistake. You still need someone inside who manages the agency and passes on product and stock information.

### Whose name should ad accounts be in when working with an agency?

Google Ads, your Meta business portfolio, GA4 and your store platform should always be opened in the brand's name, with only access granted to the agency. In Google Ads, agencies link your account to their manager account; if you leave, you remove the link and your history stays with you. On Shopify, use a collaborator account instead of sharing the owner login.

### Can an in-house team and an agency work together?

Yes, and for most growing ecommerce brands it's the most efficient setup. The in-house team owns goals, product knowledge and creative production, while the agency runs work that needs deep expertise, such as ad management, tracking and SEO. It works when decision rights are written down and both sides follow one shared report.

### What is the difference between a freelancer and an agency?

A freelancer is usually a specialist in one area and a flexible choice for defined, one-off projects. An agency offers several specialties under one contract, and the team takes over when someone leaves. If you need several channels managed together, coordinating multiple freelancers gradually becomes a separate workload for you.
