An ecommerce marketing agency does not have one standard monthly cost. A narrow mandate and an integrated scope covering strategy, media, retention, creative and Shopify execution are different investments. The useful comparison is not the headline retainer alone. It is the total operating cost of getting the required work done with clear ownership.
Shopify's 2026 hiring guide does not provide a standardized ecommerce-agency rate. It says pricing varies by scope and commercial model and recommends obtaining written inclusions, exclusions and fee-change rules. See Shopify's guide to hiring a digital marketing agency.
At 1 At Bat Media, ongoing engagements start at approximately $5,000 per month, depending on scope and client market. The proposal—not this article—controls the currency, included work, exclusions and commercial terms for a specific engagement.
Publisher disclosure: This guide is published by 1 At Bat Media, an ecommerce growth agency. It explains our approach to evaluating agency cost and includes our current starting-price language. It is educational content, not an independent market-pricing study, financial advice, a performance guarantee or a quote for a specific engagement. No client data, testimonials or case-study results are used.
The short answer
Common ecommerce agency pricing structures include a monthly retainer, a percentage of media spend, a fixed project fee, an hourly fee, a hybrid of those models or a fee with a performance component. The right model depends on what the agency owns, how workload changes, which specialists are required and how risk is shared.
Before comparing proposals, separate five cost buckets:
- Agency fees for strategy, management and execution.
- Media spend paid to advertising platforms.
- Pass-through costs such as creators, production or specialized contractors.
- Technology and implementation costs such as software, data work or development.
- Internal operating cost for approvals, assets, merchandising, finance, inventory decisions and agency management.
Then normalize the scope and calculate the additional contribution required to cover the change. A lower retainer can be the more expensive operating model if major responsibilities remain unowned. A higher retainer can also be poor value when the brand pays for capabilities it does not need.

What does an ecommerce agency retainer include?
A proposal may show one monthly number while leaving several other costs elsewhere. Put every cost into the right bucket before deciding whether two proposals are comparable.
| Cost bucket | Examples | Question to resolve |
|---|---|---|
| Agency fee | Strategy, channel management, reporting, meetings and agreed execution | Which outcomes, deliverables, people and hours or capacity are included? |
| Media spend | Meta, Google, TikTok, Amazon or other platform spend | Is the brand paying the platform directly, and is spend reported separately from fees? |
| Creative and production | Static assets, editing, studio production, photography, creators, UGC and usage rights | Is production included, capped, marked up or passed through at cost? |
| Technology and data | Klaviyo, analytics, attribution, feed tools, testing tools and other software | Which tools are required, who contracts for them and who retains access? |
| Development and implementation | Shopify changes, landing pages, tracking, feeds, integrations and migrations | Is implementation included, estimated separately or subject to change orders? |
| Internal operating time | Briefs, approvals, inventory input, merchandising, finance, legal and stakeholder management | What must the client's team supply, and how quickly? |
| Transition cost | Onboarding, documentation, access repair, asset transfer and offboarding | What happens at the start and end of the relationship? |
Google requires third-party partners, when sharing Google advertising cost, to report the exact amount charged by Google exclusive of their own fees. A separate management fee must be disclosed to new customers in writing before the first purchase and on all customer invoices. See Google's third-party transparency requirements.
This distinction also matters when calculating customer acquisition cost. Shopify's 2026 acquisition guide includes advertising, creative, agency and contractor fees, creator fees, software and allocated internal acquisition-team time in the costs that can belong in a full CAC calculation. See Shopify's ecommerce customer-acquisition guide.
Ad spend and agency fees answer different questions. Keep them separate in the contract and reporting, then combine the appropriate acquisition costs when evaluating business economics.

Common ecommerce agency pricing models
No pricing model is automatically fair or unfair. The commercial structure should match the work and make incentives, scope changes and risk understandable.
| Pricing model | How it works | Often useful when | Main question to ask |
|---|---|---|---|
| Fixed monthly retainer | A recurring fee covers a defined operating scope | Work is ongoing and capacity is reasonably predictable | What is included, what is capped and what triggers a scope change? |
| Percentage of media spend | The fee changes with managed advertising spend | Management workload and risk genuinely rise with spend | Does the service expand as the fee rises, and are minimums or tiers defined? |
| Hybrid retainer plus spend percentage | A base fee covers core work and a variable fee changes with spend | The account needs stable strategic coverage plus scalable media management | Which responsibilities belong to each component? |
| Fixed project fee | One price covers a defined deliverable or implementation | The output and acceptance criteria can be specified in advance | What assumptions, revisions, dependencies and change-order rules apply? |
| Hourly or capacity-based fee | The client pays for time or a reserved amount of capacity | Priorities vary and the work cannot be predicted precisely | Who can use the capacity, at what rates and with what reporting? |
| Performance component | Part of the fee depends on an agreed result | The baseline, attribution, margin, exclusions and client responsibilities can be defined credibly | Which result is rewarded, who controls it and how are attribution and refunds handled? |
Percentage-of-spend pricing can become misaligned when the fee rises automatically but service depth does not. A fixed retainer can become misaligned when workload grows materially without a scope review. Performance pricing can become misleading when the contract rewards platform-attributed revenue without accounting for margin, existing demand, returns or the client's own contribution.
The right response is not to reject a model by name. Write down what changes the fee, what the agency controls, what the brand controls and how both sides will handle an ambiguous result.
What changes the cost of an ecommerce agency
Scope and channel count
Managing one mature paid-media channel is a different mandate from coordinating Meta, Google, Klaviyo, performance creative and Shopify conversion. More channels do not only add tasks; they add planning, handoffs, data reconciliation and decision rights.
The ecommerce growth feedback loop explains how those functions exchange evidence when they operate under one shared system.
Depth of execution
“Strategy” can mean a quarterly recommendation or hands-on weekly ownership. “Creative” can mean briefs, editing, original production, creator sourcing, usage rights or all of them. “Email” can mean campaigns only, or campaigns, flows, segmentation, deliverability, design and copy. Require operational definitions.
Seniority and team structure
The fee may reflect access to a senior strategist, channel specialists, analysts, developers or creative operators. Confirm who will actually work on the account after the sale, how much decision authority they have and which work is subcontracted.
Media volume and account complexity
Higher spend can increase the cost of mistakes, reporting requirements, campaign volume, stakeholder scrutiny and testing opportunities. Spend alone does not prove that workload rises in a straight line. Ask the agency to explain the relationship between spend and fee.
Creative volume and production method
The number of concepts, formats, variations and markets can materially change cost. So can creator payments, raw-footage ownership, licensing, whitelisting, reshoots, studio requirements and editing depth.
Shopify and technical work
Landing-page builds, theme work, feed repair, analytics implementation, migrations and custom integrations can require specialist capacity beyond ongoing marketing management. Confirm whether these are included, separately scoped or routed to another provider.
Measurement and reporting requirements
Basic platform reporting is less involved than reconciled reporting across advertising platforms, Shopify, GA4, Klaviyo, finance and cohort views. Advanced experimentation or data engineering can add real work. More dashboards do not automatically mean better decisions.
Speed, geography and stakeholder load
Multiple markets, languages, brands, legal reviews, product lines and approval layers increase coordination. A compressed launch or turnaround may require reserved capacity that a normal cadence does not.
The Four-Layer Agency Cost Framework
The following framework is 1 At Bat Media's decision tool, not an accounting standard or a universal pricing formula.
Layer 1: Build the complete investment map
For each proposal, record:
Agency-model non-media operating cost = agency fees + pass-through production and creator costs + software and data costs + implementation work + internal client-management time + uncovered specialist work + transition cost
Total agency-model investment = agency-model non-media operating cost + media spend
Show the two components separately. If the proposed model changes media investment, record the change explicitly rather than burying it inside the fee comparison.
Use the same period for every option. Separate one-time onboarding or migration work from ongoing monthly cost. If a cost is unknown, label it unknown rather than entering zero.
Layer 2: Normalize the owned scope
Build one responsibility map and mark each item as agency-owned, client-owned, shared, separately priced or unowned.
| Responsibility | Agency A | Agency B | Internal owner | Unresolved risk |
|---|---|---|---|---|
| Commercial strategy and priorities | ||||
| Meta and Google management | ||||
| Creative strategy and briefs | ||||
| Asset production and usage rights | ||||
| Klaviyo campaigns and flows | ||||
| Shopify implementation | ||||
| Measurement and data QA | ||||
| Inventory, margin and merchandising input | ||||
| Weekly decisions and approvals | ||||
| Documentation and offboarding |
This prevents a specialist proposal from appearing cheaper simply because another team must provide strategy, creative, development or analytics.
Layer 3: Price the client-side operating burden
An agency does not eliminate internal ownership. The brand still needs someone who can set priorities, provide commercial context, approve work and resolve inventory, margin, legal and merchandising decisions.
Estimate the recurring time required from each internal role. Include the cost of work that will still go to freelancers or other agencies. Then assess whether the organization has the management capacity to coordinate the model reliably.
Do not assume an agency is inherently cheaper than an internal team. Do not compare one agency retainer with one employee's salary when the two options cover different responsibilities.
Layer 4: Calculate the contribution required to break even
Revenue alone does not determine whether the engagement is affordable. Use contribution after the variable costs your business has chosen to include.
For a simple planning comparison:
Required incremental contribution = (proposed non-media operating cost − current non-media operating cost) + (proposed media spend − current media spend)
If the result is positive:
Required incremental orders = required incremental contribution ÷ contribution per incremental order
Use the same evaluation horizon for the current and proposed models. Contribution per incremental order should be measured before the incremental agency and media costs already placed in the numerator. State the variable costs included, such as product cost, discounts, shipping and fulfillment, payment processing, returns and refunds.
Hypothetical planning example—not client data: if the proposed model incurs $10,000 in gross new monthly operating cost, eliminates $2,000 of existing contractor cost, leaves media spend unchanged and the business earns $40 of contribution per incremental order before those incremental marketing costs, the planning threshold is 200 incremental orders:
($10,000 − $2,000) ÷ $40 = 200
This is a planning threshold, not proof that the agency caused the orders. Attribution rules, seasonality, brand demand, promotions and other work can all affect reported results. Platform attribution assigns credit under configured rules; a controlled lift study provides more direct evidence of causal incrementality when the account is eligible and has sufficient volume. See Google's Conversion Lift documentation.
How to compare an agency with an in-house team
Keep this comparison narrow: which operating model can own the required work at an acceptable total cost and risk?
For the agency model, include the full investment map above. For the internal model, include salary, benefits and payroll burden, recruiting, onboarding, management time, software, creative production, contractors and the cost of specialist gaps. Compare equivalent responsibilities and time horizons.
An internal team may be the better model when the company can recruit and lead the required specialists, marketing is a core operating capability and close daily integration matters. An agency may be useful when the brand needs several capabilities sooner than it can build them internally, needs outside specialist depth or has a workload that does not justify full-time roles in every discipline. A hybrid often works when an internal leader owns the commercial direction and an agency owns defined specialist execution.
For a broader operating-model decision, use the ecommerce agency evaluation framework. This article stays focused on cost.
How to compare proposals line by line
Ask every finalist to complete the same table.
| Proposal field | What a complete answer should state |
|---|---|
| Commercial model | Retainer, percentage, project, hourly, performance component or hybrid |
| Fee and currency | Exact amount, billing currency, taxes and payment timing |
| Scope | Specific responsibilities and deliverables, not only service labels |
| Named team | Roles, seniority, allocation and who owns weekly decisions |
| Variable costs | Spend tiers, pass-through costs, markups, overages and change-order rules |
| Creative | Briefs, concepts, formats, quantities, production, creators, revisions and usage rights |
| Technology | Required tools, contract owner, data access and cancellation responsibility |
| Development | Included capacity, hourly rates, estimates and acceptance criteria |
| Reporting | Data sources, definitions, cadence, access and interpretation |
| Client responsibilities | Inputs, approvals, assets, inventory and turnaround expectations |
| Account and asset control | Ownership, administrator access, source files and transfer process |
| Term and exit | Initial term, renewal, notice, termination, transition and documentation |
Shopify's 2026 hiring guide similarly recommends defining scope, asking what is included and excluded, clarifying how fees change with ad spend or workload and comparing value rather than price alone. See Shopify's guide to hiring a digital marketing agency.
Do not convert every difference into a dollar if the estimate would be fictional. Mark the uncertainty, assign an owner and decide whether the risk is acceptable.
Account ownership, fee transparency and exit risk
The brand should understand who controls its advertising, ecommerce, analytics and lifecycle accounts before work begins.
Account access and account ownership are different. Google explains that linking an existing client account preserves its history and original-user access; billing and payment methods also remain unchanged unless consolidated billing is configured. The manager does not receive administrative ownership by default. See Google's manager-account linking documentation.
Use brand-controlled accounts where practical, give each person an appropriate individual role and document recovery access. Do not share personal credentials. See Google's account-security guidance. The agreement should state who owns:
- advertising and platform accounts;
- Shopify store access and domains;
- GA4, tag management and reporting assets;
- Klaviyo accounts, lists, templates and flows;
- creative source files, raw footage and usage rights;
- landing pages, code, feeds and integrations;
- historical data, documentation and test records.
Also define the exit procedure. A low fee can create a high switching cost when the brand cannot recover accounts, source files, data or documentation.
When a lower agency fee creates a higher total cost
A lower fee can cost more when:
- strategy remains unowned;
- senior involvement ends after the pitch;
- creative production is quoted separately after launch;
- the brand must hire another specialist for retention, development or analytics;
- reporting requires extensive internal reconciliation;
- fee tiers rise automatically without a corresponding service change;
- weak documentation makes transition slow or risky;
- the team optimizes platform attribution without connecting it to CAC, contribution or customer value;
- slow approvals and unclear decision rights waste paid capacity.
A higher fee is not automatically better. It can be poor value when:
- the scope contains channels or capabilities the brand does not need;
- the agency reserves senior people who rarely participate;
- deliverables are based on volume rather than learning or business priorities;
- the operating model duplicates a capable internal team;
- the commercial structure rewards spend or attributed revenue without appropriate guardrails.
The best-value proposal is the one that gives every material responsibility a capable owner, makes the full cost visible and fits the brand's current constraint.
What 1 At Bat Media costs and who is a fit
1 At Bat Media's ongoing engagements start at approximately $5,000 per month, depending on scope and client market. A specific proposal confirms the currency, responsibilities, production requirements, technology, pass-through costs and commercial terms.
The agency is designed primarily for established North American consumer brands with proven demand and a Shopify-led DTC growth mandate, typically generating $5 million to $50 million in total annual revenue. Larger brands can also fit. The senior-led model supports one or more of the following areas:
- Meta and Google paid media;
- Klaviyo email and SMS;
- performance creative;
- UGC and influencer marketing;
- Shopify development and conversion support;
- Amazon advertising.
The model is generally not designed for pre-revenue brands, unvalidated products, accounts below the engagement threshold or one-off tactical requests without a broader growth mandate.
Explore full-service ecommerce growth support or review ecommerce paid media management if those scopes match the current constraint. For a specific price, discuss scope and engagement fit.
Frequently asked questions
How much does an ecommerce marketing agency charge per month?
There is no standardized monthly price. A narrow service and an integrated multi-channel mandate are not comparable. Scope, pricing model, team, workload, production, technology and implementation all affect the cost. Ask for a written scope, complete cost map and explicit client responsibilities.
What does 1 At Bat Media charge?
Ongoing engagements start at approximately $5,000 per month, depending on scope and client market. The proposal confirms currency, included work, exclusions and terms. This article is not a quote.
Is ad spend included in an agency retainer?
Do not assume it is. Media may be billed directly by the platform or through another documented arrangement; the contract should identify the payer and separate platform cost from agency compensation. Google requires third-party partners to disclose their management fees and to report Google advertising cost exclusive of their own fees when that cost is shared.
Should agency fees be included in ecommerce CAC?
Use this structure: fully loaded CAC = acquisition-specific sales and marketing cost for the period ÷ new customers acquired in the same period. Include the documented acquisition portion of a mixed agency retainer, exclude retention-only work and use a consistent allocation method. Shopify's 2026 CAC guidance also includes relevant creative, creator, software and proportional internal acquisition costs.
Is a flat retainer better than percentage of ad spend?
Neither is universally better. A flat retainer offers predictability but needs clear scope-change rules. Percentage pricing can adapt as spend grows but should explain why the service or risk changes with the fee. Compare incentives, included work, minimums, tiers and overages.
Are creative production and creator fees usually included?
There is no universal rule. Some agencies include defined creative capacity; others price production, creators, usage rights or raw footage separately. The proposal should state quantities, formats, revisions, licensing, markups and ownership.
Are onboarding, implementation and change orders normally separate?
There is no universal rule. A proposal should separate one-time onboarding, migration or implementation work from the recurring fee and define the assumptions that trigger a change order. Unknown work should be estimated or marked unknown rather than silently treated as included.
Is an ecommerce agency cheaper than an in-house team?
It depends on equivalent scope. Compare the agency's full operating cost with salary, benefits, recruiting, management, software, production, contractors and specialist gaps for the internal model. An agency is not automatically cheaper, and one employee is not equivalent to a multi-specialist team.
How do I calculate whether an agency retainer can pay back?
Estimate the additional operating-model cost plus any additional media spend, subtract costs the new model displaces and divide the remainder by contribution per incremental order. Treat the result as a planning threshold. Attributed revenue alone does not prove incremental contribution.
Who should own the Google Ads, Shopify, GA4 and Klaviyo accounts?
The brand should retain durable administrative control and recovery access where practical, while granting the agency the permissions required to work. Document account, data, creative and code ownership before onboarding and define the offboarding process.
Compare total operating cost, not only the retainer
The headline fee matters, but it is only one part of the decision. Separate agency compensation from media and pass-through costs, normalize responsibilities, include the internal operating burden and translate the difference into a contribution threshold the business can understand.
That process will not make every proposal identical. It will reveal what the brand is actually buying, which risks remain and whether the operating model fits the work that needs to be done.
