SHOPIFY AGENCY VS IN-HOUSE
Quick answer
Hire in-house when Shopify is your main channel, the work is steady every week, and you can afford and manage a full team. Hire an agency when you need several specialist skills at once (paid media, CRO, development, retention, and analytics), when the work comes in waves, or when Shopify has to be run together with Amazon and other channels. Many growing brands use a hybrid: an in-house owner who makes decisions, plus an agency that executes the specialist work.

The decision in one table
The right answer depends less on company size and more on what kind of work you need done, how often, and who will own the results.
| Work area | In-house fits when | An agency fits when |
|---|---|---|
| Strategy and ownership | You have a leader who can set targets, approve tradeoffs, and own the P&L for the store | Nobody internal has run a store at your next stage of growth yet |
| Paid media (Meta, Google, TikTok) | Spend is large enough to keep a specialist busy full time | You need several ad platforms covered without hiring several specialists |
| Theme and development work | You ship site changes every week and need someone on call | Development comes in projects, such as a migration, redesign, or app cleanup |
| Conversion rate optimization | You have enough traffic to test continuously and someone to run tests | You need a structured audit and testing roadmap before committing headcount |
| Email, SMS, and retention | Lifecycle marketing is a core growth lever you want to build long term | Flows need to be rebuilt once, then maintained |
| Analytics and attribution | You have a data person who already owns reporting | Shopify, ad platform, and GA4 numbers disagree and nobody can reconcile them |
| Multichannel operations | Shopify is your only channel | Shopify, Amazon, and TikTok Shop compete for the same inventory, budget, and customers |
What an in-house Shopify team usually includes
A store that is run fully in-house typically needs these roles covered, either as separate hires or combined in fewer people:
- Ecommerce lead: owns revenue, margin, and the roadmap for the store.
- Performance marketer: runs Meta, Google, and other paid channels, including creative testing.
- Developer or technical marketer: maintains the theme, apps, tracking, and site speed.
- Designer or content lead: produces product imagery, landing pages, and ad creative.
- Retention marketer: owns email, SMS, subscriptions, and loyalty.
- Analyst: keeps Shopify reports, GA4, and ad platform data consistent.
The common failure mode is not the lack of one role. It is that one or two people try to cover all six, and the specialist work (tracking, testing, creative volume) slips first.
What each option costs
Use real salary data for the in-house side and written quotes for the agency side. Avoid comparing a single salary with a full agency retainer, because they rarely cover the same scope.
In-house salary benchmarks (U.S., base wages only). The U.S. Bureau of Labor Statistics reports these May 2024 median annual wages:
- Marketing managers: $161,030 median. The lowest 10 percent earned less than $81,900 and the highest 10 percent earned more than $239,200.
- Web developers: $90,930 median. The lowest 10 percent earned less than $48,560 and the highest 10 percent earned more than $162,870.
- Web and digital interface designers: $98,090 median.
These figures are base wages. The full cost of an employee also includes benefits, payroll taxes, recruiting, management time, software seats, and the time it takes a new hire to become productive.
Agency costs. There is no reliable public benchmark for Shopify agency fees, because pricing depends on scope. Common structures are a monthly retainer, a percentage of ad spend, a project fee for builds and migrations, or a combination. Ask every agency for a written scope that lists exactly which channels, deliverables, meetings, and reports are included, then compare that scope with the roles you would otherwise need to hire.
When in-house is the better choice
- Shopify is your primary or only sales channel and the workload is steady every week.
- You already have an experienced ecommerce leader who can hire and manage specialists.
- Brand knowledge, speed of internal approvals, or product complexity make outside execution slow.
- You want to build long-term capability, such as an in-house creative studio or data team.
When an agency is the better choice
- You need several specialist skills at once and cannot justify a full-time hire for each.
- Work comes in waves: a replatform, a redesign, a peak-season push, or a new market launch.
- Results have stalled and you need an outside team that has seen the same problems in other stores.
- Shopify has to be coordinated with Amazon, TikTok Shop, or wholesale, and no internal team owns all of them.
The hybrid model most growing brands end up with
A hybrid keeps decisions inside the company and moves specialist execution outside. A typical split is an in-house ecommerce lead who owns targets, budget, and priorities, and an agency that runs paid media, CRO, development sprints, and reporting. The hybrid works when three things are written down: who approves spend and site changes, which metrics define success, and who owns the data and accounts if the relationship ends.
A 30-day way to decide
- List the work. Write down every recurring Shopify task for the last 90 days and how many hours it took.
- Group it by skill. Separate strategy, paid media, development, creative, retention, and analytics.
- Price the in-house version. Use the salary benchmarks above plus benefits and tools for each role you would need.
- Get two or three agency scopes. Ask each agency to price the same task list, not a generic package.
- Decide ownership first. Whatever you choose, make sure your company owns the Shopify store, ad accounts, analytics, and creative files.
Questions to ask a Shopify agency before you hire
- Who works on the account day to day, and how many other accounts do they manage?
- Which tasks are included in the fee, and which are billed separately?
- How do you measure success: platform ROAS, or contribution margin and new customer growth?
- How do you reconcile Shopify, GA4, and ad platform numbers?
- What happens to accounts, code, and creative if we stop working together?
How Eva helps
Eva runs Shopify as part of a connected commerce system, alongside Amazon and TikTok Shop, so acquisition, conversion, inventory, and retention decisions share one owner and one set of numbers. Eva is an Amazon Ads Advanced Partner, which matters for brands whose Shopify customers also search for them on Amazon. Many brands work with Eva in the hybrid model above: their team keeps strategy and approvals, and Eva handles specialist execution and reporting.

Frequently asked questions
Is it cheaper to hire a Shopify agency or an in-house team?
It depends on scope. One in-house marketing manager in the U.S. had a median base wage of $161,030 in May 2024, according to the Bureau of Labor Statistics, before benefits and tools. An agency can be cheaper when you need several specialist skills part time, and more expensive when you need one skill full time. Compare written agency scopes against the full set of roles you would need to hire.
When should a Shopify brand move from an agency to in-house?
Consider moving work in-house when a specific discipline has steady, full-time workload, when you have a leader who can manage that hire, and when speed of internal decisions matters more than outside experience. Many brands move one function at a time rather than all at once.
Can I use an agency and an in-house team together?
Yes. A hybrid model is common: an in-house ecommerce lead owns targets, budget, and approvals, and an agency executes paid media, CRO, development, or reporting. Write down who approves changes and which metrics define success before you start.
What should a Shopify agency contract include?
A written scope of channels and deliverables, named team members, reporting cadence, the metrics used to judge performance, notice period, and a clause confirming that your company owns the Shopify store, ad accounts, analytics properties, code, and creative.
Does Eva work with brands that already have an in-house team?
Yes. Eva often works alongside in-house teams, handling specialist execution across Shopify, Amazon, and TikTok Shop while the brand’s team keeps strategy and approvals.
