How much does a Shopify marketing agency cost?

The Real Numbers for a Shopify Store

Expect a $1,500–$7,500 CAD monthly retainer to a Shopify marketing agency, with the exact figure set by how many channels you run and your monthly ad spend. That fee buys management — not media, not your Shopify plan, not apps.

The retainer is the ongoing fee for ongoing work: running Google and Meta ads, doing e-commerce SEO on collection and product pages, building email and SMS flows, and producing content. A single channel — just paid ads, or just SEO — usually sits at the lower end, often $1,500–$3,000. A full-funnel program that coordinates paid acquisition, SEO, email, and creative together typically runs $5,000–$10,000+, because there are more moving parts and more senior oversight keeping them aligned to revenue.

Then there are costs that are not the agency's fee but land on the same credit card. Ad spend goes straight to Google and Meta; most e-commerce SMBs run $2,000–$10,000 a month there, and a '$1,500 ads' quote almost always means $1,500 of management on top of that. Your Shopify subscription is $39–$399/month plus per-sale transaction fees. Paid apps — Klaviyo or similar for email, a reviews app, an upsell app — add their own monthly fees. And a store rebuild is a separate one-time project: $5,000–$15,000 for a templated build, $15,000–$50,000+ for a heavily customized one. Add these up before comparing quotes, or you'll think one agency is cheaper when it has simply left costs off the page.

What Drives a Shopify Agency's Price

Two agencies can quote double the difference for the same Shopify store, and the gap comes down to a few things specific to e-commerce.

Catalogue size and complexity matter more here than in lead-gen. A store with 30 SKUs and one collection is far less work than a 2,000-SKU catalogue with variants, seasonal drops, and a feed pushing every product into Google Shopping and Meta catalogue ads. Feed management — keeping titles, images, prices, and stock accurate across channels — is real ongoing labour that quietly drives the number.

Who does the work is the factor buyers underestimate most. A retainer where a senior strategist owns your account costs more than one where a junior runs a templated checklist across forty stores — and the difference shows in return on ad spend, not just the invoice. Cheap e-commerce retainers are often cheap because they're a thin layer over Shopify's default apps and automated reports.

Channel mix sets the rest. Email and SMS are high-return and relatively cheap to run; paid social and Shopping management get pricier as spend and creative volume rise, because someone has to keep producing ad creative that doesn't fatigue. A store leaning on one channel pays less than one running acquisition, retention, and content together. As always, ask any quote to separate management from ad spend, app fees, and your Shopify plan — it's the fastest way to compare like with like.

The Pricing Models You'll See

Shopify agencies price one of four ways, and each is fair in a particular situation.

Flat monthly retainer — a fixed fee for a defined scope. This is the cleanest model for SEO, email, content, and full-funnel work because it doesn't penalize you for growing. It's the right default for most stores and what we use for most engagements.

Percentage of ad spend — common for Google Shopping and Meta management, usually 10–20% of what you spend on the platform. It's simple, but it carries a built-in conflict: the agency earns more when you spend more, profitable or not. It's fine at smaller budgets; above roughly $10,000/month in spend, a flat management fee is usually fairer.

Percentage of revenue or commission — sometimes pitched for e-commerce as 'we win when you win.' It can align incentives, but watch how revenue is attributed: if every sale, including returning customers who'd have bought anyway, counts toward the agency's cut, you can overpay. Insist on a clear attribution window and what's in or out.

Project-based — a one-time fee for a store build, a Shopify migration, or a conversion-rate audit. Right for anything with a defined start and end. There's no single correct model, but be cautious of any agency that won't explain why it prices the way it does, or that uses percentage-of-spend on a large budget with no cap.

When a Shopify Agency Is Worth It

It's worth it once the cost of getting acquisition wrong exceeds the management fee — which for most stores happens the moment they put real money into ads. Below that, you may be better off learning the basics yourself.

The case against an agency is honest at the smallest scale. If your store is doing a few sales a week and you can only spare $500–$800 a month total, most capable agencies can't do meaningful work for that. You're better off setting up Shopify email flows, getting your product feed clean, collecting reviews, and learning Meta ads yourself until the store can fund a real engagement. We say this even though we are an agency, because a $500 retainer that produces nothing is worse than none.

The case for an agency strengthens fast as spend rises. Once you're putting $3,000–$10,000 a month into Google Shopping and Meta, the cost of a poorly structured account, a broken conversion tag, or creative that never gets tested quickly dwarfs the management fee. A good Shopify agency doesn't just run ads — it fixes the leaks: an abandoned-cart flow that isn't firing, product pages that don't convert the traffic you're paying for, a feed that's suppressing half your catalogue.

A useful test: total a year of agency fees, then estimate what you'd lose in wasted ad spend, slow ramp, and your own hours doing it part-time. If the agency number is smaller, it's worth it. For most stores past the hobby stage, it is.
