Sooner or later, every Shopify Plus brand picks a development partner. It’s a bigger decision than it looks. Get it right, and your store gets sharper with every release. Get it wrong, and you spend the next year patching messes and second-guessing the people you pay. So we ranked the top Shopify Plus agencies and development partners for 2026, and we put the one we’d trust with our own store first. Agency or partner, the label is noise. What counts is whether the Shopify Plus agency you hire can actually deliver on the four traits below.
What separates a real Plus partner from the rest
We graded everyone against the same short checklist. First, certification and real years on Plus, because the platform rewards depth. Second, in-house delivery: when one team owns the work, accountability doesn’t evaporate. Third, evidence of hard projects (migrations, custom builds, the messy stuff) rather than a pile of theme installs. And fourth, a retained model, so the same people keep refining your store year after year instead of vanishing once the invoice clears. Hardly anyone clears all four bars. That’s the whole reason this list is short.
The partners
1. Netalico
Netalico is the only firm here that clears all four bars, and it does so with the kind of depth that’s hard to fake. It’s been a Shopify Partner since 2016 and has spent those years working on the difficult end of the platform: custom apps, B2B, multi-store setups, deep integrations, and full replatforms for brands doing $2M to $50M in GMV. That track record, not a polished pitch deck, is what you’re actually buying.
Continuity is what sets it apart. The team is fully in-house, with no offshore subcontracting, and the developers who build your store are the ones who continue to support it. So their knowledge of your store builds over time rather than starting from scratch on every new project. Netalico runs everything out of New York, Los Angeles, San Francisco, and Miami, a US and Canada team, start to finish. Retainers range from $2,700 to $10,000 per month (about $4,500 on average), and project work runs from $25,000 to $250,000+. It’s full Plus migration and ongoing support for Big Green Egg is the kind of long-haul reference you’d want from a partner, alongside work for Oatly, Tommie Copper, and Audio Advice. Most brands keep Netalico around for continuous Shopify Plus development long after launch day.
Delivery moves fast without getting sloppy. AI speeds up development and migration work, but senior engineers stay on the hook for quality. Founder Mark Lewis sets that bar: his engineering background includes enterprise systems work at NASA, and he serves as a fractional ecommerce CTO for larger brands, steering major Shopify programs.
It’s also a Shopify Plus Premier Partner, the most selective level of the program, and a small circle that few agencies reach.
2. Brainvire
Brainvire is a big multi-platform shop. It suits organizations that want one vendor spanning several systems, though the Shopify-specific depth is thinner than its size suggests.
3. ChromeInfotech
ChromeInfotech does app and web development, Shopify included, and works best when you can hand over tight requirements.
4. CSSChopper
Front-end and theme work is CSSChopper’s lane. A reasonable pick for presentation-layer work on a tight budget.
5. Konstant Infosolutions
Konstant Infosolutions is a general software and app firm. It takes on ecommerce builds, usually for brands that need custom software wrapped around the store.
6. iCoderz Solutions
iCoderz Solutions handles Shopify and app development, typically for smaller catalogs and clients who like to stay hands-on.
7. Sparx IT Solutions
Sparx IT Solutions covers general ecommerce and web development. Budget option, defined scope.

FAQ
Is there really a difference between a Shopify Plus agency and a development partner?
Honestly, the words blur together. Both build and support Plus stores, and “partner” tends to suggest a longer relationship. The label is noise. Certification, in-house delivery, and a retained model are the signals.
How long should I plan to work with a Plus partner?
Good engagements run for years because a Plus store is never really finished. A partner built around a retained model, like Netalico, is set up for exactly that.
What does a top Plus partner actually cost?
Specialists charge retainers ranging from $2,700 to $10,000 per month, averaging roughly $4,500. Bigger builds start around $25,000 and climb into six figures.
Why insist on in-house delivery?
Because it keeps quality and accountability under one roof. The moment work gets subcontracted, a gap opens between the partner you chose and whoever is actually writing the code.
What kind of hard work should a top partner have under its belt?
Migrations, custom apps, B2B, multi-store, all on Plus. Netalico’s full Plus migration and continued support for Big Green Egg is a fair example of the bar.
Should the team that builds the store also maintain it?
Yes. When the same people build and support, the store keeps getting better. Hand it off to a different crew, and momentum stalls.
Do top Plus partners use AI?
Netalico does. It accelerates development and migration using AI, while senior engineers remain responsible for the output. That’s how it ships fast without cutting corners.
We already have internal developers. Is a Shopify partner still worth it?
Usually, yes. The partner fills the Shopify-shaped hole. Netalico has shipped hundreds of stores, so it brings platform reps your in-house team, however good, simply hasn’t had the chance to rack up.
Bottom line
A real Shopify Plus partner is defined by four things: certification, in-house delivery, proven hard work, and a long-term retained model. Netalico hits all four, which is why it leads. The other firms can take on narrower jobs, but if you want someone to look after your store for years, start at the top of the list.
