I’ve sat on both sides of this question. At Amazon, I led software teams and had to decide what engineering time was worth. At Daily Bloom, the Shopify brand I co-founded, I’m the one paying the app bills and the agency invoices. So here’s the straight answer.
A fractional CTO for a Shopify brand usually costs $4,000 to $25,000 a month, depending on how many hours you need. My own retainers start at $1,500 a month for a lighter advisor role, or $4,000 a month for about one day a week. Most brands start with my $1,500 fixed-price audit instead.
What the market charges
Most fractional CTOs price by monthly hours, not by the hour. These are typical US ranges right now:
For comparison, a full-time CTO runs about $400,000 in the first year once you count salary, equity, benefits, and recruiting. For a Shopify brand, that’s almost never the right hire.
What I charge
The Advisor role is lighter than a typical advisory engagement: about six hours a month of calls, email, and reviews. I built it for smaller stores that need a second opinion more than a second pair of hands.
Every engagement is fixed scope, and you can stop after the audit and keep everything in it. I’d rather you hire me again because the audit was useful than because you’re locked in.
Why you need fewer hours than a startup does
Shopify already runs your hosting, checkout, security, and uptime. Nobody on your payroll is keeping servers alive at 2 a.m. What you’re paying for is judgment about everything bolted on top: the apps, the integrations, the theme, your agency’s work, and where AI can take tasks off your plate.
For most brands doing $500K to $20M a year, that fits in about one day a week.
A story from my own store
Daily Bloom was on Shopify Plus. When I finally sat down and listed what Plus gave us that we’d actually miss, the list was close to empty. Scripts were gone, checkout changes had moved to apps, Shopify Flow now works on every plan, and even B2B comes in a basic form on the lower plans. The one real argument left was card processing, since higher plans get lower rates. So I ran our order volume against the fees, and in our quieter months it wasn’t close. Plus starts at about $2,500 a month and Grow at about $105, so moving to Grow saves us roughly $2,400 a month. That’s three and a half times what I saved cutting apps.
That’s the kind of thing a fractional CTO should find in the first two weeks, not the second year.
What pushes the price up
A headless storefront or custom apps someone has to maintain
More than one agency or freelancer working on the store at once
A replatform, ERP, or 3PL change coming in the next six months
An in-house developer or small team who needs a manager
When you don’t need one
I’ll say it plainly: plenty of stores don’t need me. Skip it if all of these are true:
You’re on a standard theme with a handful of apps
Your developer or agency spend is small, and you trust the invoices
You have no big platform decisions coming in the next six months
In that case, put the money into ads or inventory. Shopify’s built-in tools will carry you further than a CTO would.
When it pays for itself
The math usually comes out of money you’re already spending. Brands doing $1M to $5M a year typically spend $1,000 to $3,500 a month on apps, and a mid-market agency retainer often runs $5,000 to $10,000 a month. At Daily Bloom, my first pass through our apps cut $683 a month on its own, enough to cover a $1,500 audit in about two months. I walk through how in how to cut your Shopify app bill.
