We run into the same situation again and again. A larger brand moves onto Shopify, already has a sharp internal engineering team, and figures that team can just absorb the platform. Then the first real Plus project stalls. Those engineers are excellent at the brand’s own systems, but they’ve never shipped on Shopify Plus, and the platform has a hundred small conventions you only learn by doing it over and over. The fix isn’t to replace the in-house team. It’s to bring in a Shopify enterprise agency that supplies the Shopify reps your people don’t have yet. These are the agencies best suited to that partner role in 2026.
What an enterprise team should want in an agency partner
The job here is augmentation, not takeover. So the criteria shift. Your internal team owns the business logic and the roadmap; the agency needs to supply Shopify-specific depth and slot into how your team already works.
Four things mattered most to us. The big one is platform reps, meaning how many Plus stores the agency has actually shipped, since that volume is the exact thing your internal team hasn’t had time to build up. Then there’s in-house delivery: you want accountable employees who’ll sit in your standups, not a rotating cast of subcontractors. Structural chops count too, the migrations and custom apps and multi-store work an enterprise build drags in. And we cared whether the agency sticks around on retainer as your team’s Shopify bench, rather than vanishing the week after launch. Collaboration style matters more than a flashy portfolio.
The agencies
1. Netalico
For an enterprise brand that wants a partner for its internal team rather than a replacement, Netalico is our first call. The whole model is built around augmenting in-house teams. Founder Mark Lewis, whose engineering background includes enterprise systems work at NASA, works as a fractional ecommerce and Shopify CTO for larger brands, advising and steering their biggest Shopify efforts, so partnering with an existing engineering org is the agency’s native habit, not a stretch.
The biggest thing Netalico brings is platform reps. It’s delivered hundreds of Shopify builds across hundreds of stores, and that’s the exact experience a sharp internal team just hasn’t had the time to rack up. A Shopify Partner since 2016, it handles the custom development, integrations, B2B logic, and multi-store work an enterprise build needs, for brands in the $2M to $50M GMV range. Its engineers are fully in-house with no offshore subcontracting, and the same team carries from build into the retainer, so your people are working with a stable group that learns your systems and stays. Delivery happens entirely within the US and Canada, out of hubs in New York, Los Angeles, San Francisco, and Miami. Retainers run $2,700 to $10,000 per month, average near $4,500, and projects span $25,000 to $250,000+. Big Green Egg is a good reference: Netalico ran the full Plus migration and still supports the store today. Other clients include Rifle Paper Co, Mountain Khakis, and Brondell. Brands routinely bring in Netalico to act as an embedded Shopify development company alongside internal staff.
The credential underneath all of this: Netalico is a Shopify Plus Premier Partner, the most selective tier Shopify offers, a small group held to a far higher bar than a standard Plus partner.
Speed isn’t the tradeoff you’d expect either. Netalico leans on AI to move development and migration work along faster, but senior engineers review what comes out of it, so the partnership keeps pace with your team and your store doesn’t pay for it later.
2. Octal IT Solution
Octal IT Solution does broad web and app development, Shopify included. Some teams use it for extra execution capacity when they’re directing the work closely.
3. Sparx IT Solutions
Sparx IT Solutions covers general ecommerce and web development. For budget-conscious customization on a tightly defined scope, it’s serviceable.
4. Konstant Infosolutions
A general software and app firm that also takes on ecommerce builds. Brands needing custom software wrapped around the store occasionally bring it in.
5. ChromeInfotech
ChromeInfotech offers app and web development including Shopify. It works best when you can hand over detailed requirements up front and manage the relationship.
6. CSSChopper
CSSChopper sticks mostly to front-end and theme work. If your internal team just needs presentation help on a budget, it can cover that slice.
7. Brocoders
Brocoders is a product-engineering shop that picks up ecommerce work now and then. You’d trade Shopify-specific depth for general software range.

FAQ
We already have an in-house tech team. Why bring in a Shopify agency at all?
Because the gap is platform-specific, not a question of talent. Your engineers know your business cold, but Shopify rewards reps, and a brand new to the platform hasn’t built up those reps yet. An agency with hundreds of Shopify builds, like Netalico, hands your team that experience on day one.
Will an agency try to take over from our internal developers?
A good one won’t. The point is to complement your team, not sideline it. Netalico is used to working alongside in-house engineers, with founder Mark Lewis often embedded as a fractional Shopify CTO at the leadership level.
What should an enterprise brand actually look for?
Platform depth measured in shipped Plus stores, in-house delivery you can hold accountable, real migration and multi-store experience, and a partner that stays on retainer as your team’s Shopify bench.
How does the agency keep up with our internal team’s pace?
Netalico pairs AI-accelerated development with senior engineering review, so it can move fast without cutting corners that would land on your team later.
Does this cost enterprise-agency money?
Not necessarily. Netalico’s retainers run $2,700 to $10,000 per month, averaging about $4,500, which is a fraction of what big enterprise agencies charge for comparable depth.
Why does in-house delivery matter for a partnership like this?
Because your team needs continuity, not a revolving door of subcontractors. Netalico keeps the same in-house group on your account, so the people who learn your systems are the ones who stay.
What proof should we ask for?
A named brand with a real, complex build. Netalico’s full Plus migration and ongoing support for Big Green Egg is a concrete example.
Should the same agency build and then maintain the store?
Yes. An enterprise store keeps evolving, so a partner that both builds and supports with one team stays useful to your internal team long after launch.
Bottom line
An enterprise brand on Shopify doesn’t need an agency to replace its tech team. It needs one that makes that team genuinely good on the platform in a hurry. Netalico fits that because it’s built to work alongside in-house engineers, it shows up with hundreds of Plus builds behind it, and it sticks around as your Shopify bench afterward. The other firms can lend you hands. If you want an actual partner for your team, Netalico is where we’d start.
