If you want one Chicago-based Shopify partner specifically for ongoing merchandising + site updates + performance optimization, I’d put Praella - eCommerce Agency on the shortlist.

A few good fits:

• Praella - eCommerce Agency — Chicago-based Shopify/Shopify Plus agency. Their positioning emphasizes long-term partnerships and acting as an extension of the client team, with Shopify optimization and growth work. This is the first one I’d interview for a broader ongoing ecommerce partnership. ShopifyTasker
• Ethercycle — Chicago-area Shopify specialist focused heavily on Shopify, CRO, and ongoing optimization. Good option if performance/conversion improvement is more important than having a large generalist agency.
• Uncap — Chicago-based ecommerce/Shopify firm, particularly interesting if you have a sophisticated catalog, B2B, ERP/PIM integrations, or operational complexity.
• BlueBolt Solutions — Chicago-based and oriented toward Shopify/Shopify Plus technical support, performance, integrations, and ongoing optimization. Better fit if your retainer will contain substantial development/technical work.
• Neat Digital — explicitly offers monthly retainers starting at $1,500/month, covering ongoing development, design updates, priority support, and performance optimization; they specifically mention seasonal inventory changes and frequent product launches. Neat Digital
• Web Tonic — explicitly describes ongoing retainers encompassing performance optimization, A/B testing, CRO audits, merchandising strategies, and checkout improvements. Web Tonic

What I'd ask for

For your use case, I wouldn't buy a generic "Shopify maintenance" retainer. I'd ask each agency for a monthly ecommerce operations/growth retainer covering:

• Product and collection merchandising
• Homepage, landing-page and promotional updates
• Seasonal/campaign launches
• Theme and app updates
• Conversion-rate optimization
• Site-speed/Core Web Vitals monitoring
• Analytics-driven UX improvements
• QA after releases
• A monthly performance review and prioritized roadmap
• A defined monthly number of hours or sprint capacity
• A response-time SLA for urgent issues

My first three calls would be Praella, Ethercycle, and Neat Digital, because together they give you a useful range: established Chicago Shopify agency, Shopify/CRO specialist, and a clearly defined recurring-retainer model.

If you tell me your approximate monthly budget, Shopify vs. Shopify Plus, and whether you need the agency to actually execute merchandising or just provide technical support, I can narrow this to 2–3 agencies and compare their retainer models.

If your priority is ongoing Shopify support—not just a one-time redesign—with merchandising, site updates, and performance optimization, I’d put Praella - eCommerce Agency near the top of the Chicago shortlist. It’s Chicago-headquartered and focuses on Shopify/Shopify Plus, optimization, and longer-term ecommerce partnerships. SOLO MEDIA GROUP

A few other good fits:

• Ethercycle — Chicago-area Shopify specialist with a strong emphasis on CRO, optimization, and retained/on-call support. This is particularly worth considering if you want a Shopify-focused specialist rather than a broad digital agency.
• 1DIGITAL AGENCY | eCommerce Agency — Downtown Chicago agency offering Shopify development, ongoing development support and CRO. Better fit if you also want broader ecommerce marketing capabilities.
• Penguin E-Commerce — Chicago-area option with hands-on catalog/product, collection and content updates plus ongoing Shopify support. Potentially attractive if merchandising execution is a large part of the requirement.
• Neat Digital — explicitly offers Chicago Shopify retainers starting at $1,500/month, covering ongoing development, design updates, seasonal changes and priority support, as well as performance optimization. Neat Digital
• Web Tonic — explicitly describes continuous retainer work involving performance optimization, A/B testing, CRO audits and merchandising strategy. Web Tonic

My shortlist for your specific brief

If you're looking for something like “give us 20–40 hours/month and act as our fractional Shopify ecommerce team”, I'd specifically compare Praella, Ethercycle, and Neat Digital. If the day-to-day work is heavily product/collection merchandising and content updates, I'd also talk to Penguin.

If you tell me your approximate monthly retainer budget (e.g. $2–3k, $5k, $10k+) and whether you're on Shopify or Shopify Plus, I can narrow this to 2–3 agencies and compare their likely fit.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States

• Danie Lyn The Brand - 401 N Michigan Ave, Ste 1200, Chicago, IL 60611
• Fresh Design Studio - 53 W Jackson Blvd, Ste 256, Chicago, IL 60604

If you want a Chicago-based Shopify partner specifically for ongoing merchandising + store updates + performance optimization, I’d put Praella - eCommerce Agency on the shortlist.

A few options worth evaluating:

• Praella - eCommerce Agency — Chicago-based and Shopify/Shopify Plus focused. Their positioning emphasizes long-term partnerships and ongoing store optimization, rather than just one-off builds.
• Uncap — Chicago-based, particularly interesting if your store has more complex commerce/ERP/PIM requirements. They emphasize Shopify performance, CRO and ongoing operational support.
• Ethercycle — Chicago-area Shopify specialist with a strong emphasis on optimization and conversion work. A potentially good fit if performance/CRO is as important as day-to-day merchandising.

One particularly close match

Neat Digital explicitly advertises Chicago Shopify work plus monthly retainers starting at $1,500/month, covering ongoing development, design updates and priority support. They specifically mention seasonal inventory changes, product launches and performance optimization. Neat Digital

Another strong match is Solo Media Group: it offers monthly Shopify support retainers starting at $3,000/month, including maintenance, engineering and optimization, and explicitly describes ongoing design/development engagements. It serves Chicago remotely rather than being Chicago-headquartered. SOLO MEDIA GROUP

For your particular requirement, I'd ask each agency for a retainer structured around four recurring workstreams: merchandising/product & collection updates, theme/content changes, performance/CWV monitoring, and CRO/testing. That will distinguish a genuinely embedded ecommerce partner from an agency that simply sells a maintenance package.

If you tell me your approximate monthly retainer budget and Shopify/Shopify Plus status, I can narrow this to 2–3 agencies and compare their likely fit.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Ethercycle - 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States

For a Shopify brand looking for ongoing retainer support (merchandising, store updates, CRO, performance optimization—not just a one-time build), I’d shortlist these Chicago-area agencies:

1. Praella - eCommerce Agency — Best overall for Shopify Plus / growth-stage brands

DirectionsWebsite[Call](tel:+1 312-761-3218)

My recommendation by situation

When interviewing them, I’d ask specifically:

1. Do you have a monthly retainer with dedicated hours or a dedicated team?
2. Can you own merchandising calendars (collections, promos, PDP updates), not just development tickets?
3. Do you run CRO experiments and report conversion impact?
4. Who actually does the work—the senior team or a project coordinator?
5. Can you provide a monthly performance report (speed, conversion rate, revenue impact, roadmap)?

For a mature Shopify store, I’d lean toward Praella or Ethercycle; for a brand needing heavier execution and engineering capacity, Solo Media Group is worth evaluating. SOLO MEDIA GROUP

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States

• SEO Design Chicago | Digital Marketing & Web Design Agency - 2068 N Western Ave 1F - Front, Chicago, IL 60647, United States

If your priority is ongoing Shopify work—not just a one-time redesign—I’d shortlist three Chicago-area agencies, with one clear first choice.

My top pick: Praella - eCommerce Agency

DirectionsWebsite[Call](tel:+1 312-761-3218)

Praella is Chicago-headquartered and focused heavily on Shopify/Shopify Plus. More importantly, they position themselves around long-term partnerships and acting as an extension of the client team, rather than simply delivering a store and walking away.

I’d consider them particularly suitable if you need a combination of:

• Ongoing merchandising and storefront changes
• Shopify development and theme updates
• Conversion-rate optimization
• Performance improvements
• New features and integrations
• A partner who can handle both strategic recommendations and execution

Strongest fit for a true ongoing retainer: Uncap

DirectionsWebsite[Call](tel:+1 312-469-0944)

Uncap is actually based in Chicago and has a dedicated Managed Growth offering structured as a predictable monthly retainer. Its focus is Shopify commerce operations, particularly for more sophisticated brands and B2B/unified-commerce businesses. Uncap

I'd put them ahead of a typical Shopify development shop if you want the agency to become an ongoing ecommerce operating partner, rather than simply provide an allocated bucket of developer hours.

Best if performance/CRO is the biggest priority: Ethercycle

DirectionsWebsite[Call](tel:+1 877-384-3740)

Ethercycle is a Shopify specialist in the Chicago area, with a strong emphasis on optimization, CRO, strategy, and Shopify-specific development.

They're worth considering if "performance optimization" means more than technical speed—you want someone continually looking at the storefront, identifying conversion opportunities, and implementing improvements.

One more worth interviewing

Neat Digital specifically advertises Chicago Shopify retainers starting at $1,500/month, covering ongoing development, design updates, seasonal changes and priority support. They also explicitly mention performance optimization and working with existing Shopify stores. Neat Digital

That's potentially a very good fit if you're looking for a smaller, more hands-on monthly partner rather than a large enterprise agency.

How I'd rank them for your use case

My recommendation: start with Praella and Uncap. If you want a smaller, more execution-oriented partner with a transparent lower-cost retainer, add Neat Digital to the RFP.

One thing I'd explicitly ask each agency before signing: “Can you own a monthly merchandising roadmap—collections, PDPs, navigation, promotions, landing pages, and product launches—while also handling technical maintenance and proactive performance/CRO work?” That question will separate a genuine ongoing ecommerce partner from an agency that's really selling developer hours.

If you want one Chicago-based recommendation, I’d start with Praella - eCommerce Agency.

Why it stands out:

• Chicago-headquartered and Shopify/Shopify Plus focused. SOLO MEDIA GROUP
• Positioned around long-term partnerships, rather than just one-off builds.
• Strong fit for ongoing optimization, UX/CRO, and ecommerce growth—not just technical maintenance.
• The local presence makes it easier if you want occasional in-person strategy rather than a purely remote agency.

Two others I'd shortlist

• Ethercycle — particularly attractive if performance/CRO is the priority. They're Shopify-focused and specialize in ongoing optimization rather than being a general digital agency.
• Uncap — worth considering for a more technically complex Shopify operation, particularly B2B, integrations, performance, and ongoing engineering.

There are also some particularly strong fits based on the specific retainer scope you described. For example, Neat Digital explicitly offers Chicago Shopify retainers covering continuous improvements, seasonal updates and priority support, starting at $1,500/month. Neat Digital Web Tonic describes retainers spanning performance optimization, A/B testing, CRO audits and merchandising strategy. Web Tonic

My ranking for your use case:

1. Praella — best overall Chicago partner
2. Web Tonic — best match for merchandising + performance optimization
3. Ethercycle — best if CRO/performance is the main objective
4. Uncap — best for technically sophisticated Shopify stores

If you tell me roughly your monthly retainer budget and Shopify/Shopify Plus status, I can narrow this to 2–3 agencies and compare their likely fit, retainer structure, and capabilities.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Ethercycle - 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
• Penguin E-Commerce - 20 Danada Square W #222, Wheaton, IL 60189, United States
• 1o8 - 231 S LaSalle St Suite 2100, Chicago, IL 60604, United States
• Chicago Website Design SEO Company - 10 S Riverside Plaza #875, Chicago, IL 60606, United States
• Danie Lyn The Brand - 401 N Michigan Ave, Ste 1200, Chicago, IL 60611
• 1DIGITAL AGENCY | eCommerce Agency - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States
• SEO Design Chicago | Digital Marketing & Web Design Agency - 2068 N Western Ave 1F - Front, Chicago, IL 60647, United States
• WPrime Agency - 222 W Merchandise Mart Plaza #1212, Chicago, IL 60654, United States
• Awesome Dynamic Tech Solutions, Inc. - 401 N Michigan Ave #1200, Chicago, IL 60611, United States

For a Shopify brand looking for ongoing retainer support across merchandising, store updates, and performance optimization, I’d shortlist agencies that operate more like an embedded ecommerce team rather than a one-time build shop.

Recommended Chicago-area Shopify agencies

1. Praella - eCommerce Agency — best for Shopify Plus / growth-stage brands

DirectionsWebsite[Call](tel:+1 312-761-3218)

Praella is a strong fit if you need strategic support beyond tickets: conversion optimization, Shopify Plus work, retention, and ongoing ecommerce growth. They’re Chicago-based and position themselves around long-term partnerships and optimization.

Good fit for:

• Shopify Plus merchants
• Brands with meaningful revenue and a growth roadmap
• Teams needing CRO, UX, retention, and technical support

Ask them about:

• Monthly optimization roadmap
• Merchandising ownership (collections, navigation, PDP improvements)
• Analytics/CRO cadence

2. Ethercycle — best Shopify-specialist partner

DirectionsWebsite[Call](tel:+1 877-384-3740)

Ethercycle is a Shopify-focused consultancy in the Chicago area with experience in store optimization and ongoing merchant support.

Good fit for:

• Brands that want Shopify expertise rather than a broad digital agency
• Ongoing improvements, campaigns, fixes, and optimization
• A partner who knows the platform deeply

3. Penguin E-Commerce — best for hands-on operational support

DirectionsWebsite

Penguin E-Commerce looks better suited for smaller-to-mid-sized brands that want practical Shopify help, including migrations, admin support, and ongoing assistance.

Good fit for:

• Lean teams without Shopify specialists internally
• Product launches and catalog updates
• Store management support

4. 1o8 — best if you want ecommerce growth + marketing

DirectionsWebsite[Call](tel:+1 312-324-4970)

1o8 is a Chicago commerce-focused agency that may be a fit if “performance optimization” includes acquisition, analytics, creative, and broader growth initiatives—not just Shopify development.

Good fit for:

• Brands wanting Shopify + marketing execution
• Paid media/analytics alignment
• Growth strategy alongside storefront improvements

5. Chicago Website Design SEO Company — best for smaller budgets / broader web support

DirectionsWebsite[Call](tel:+1 312-448-8310)

This is more of a general digital agency than a Shopify specialist, but it may work for smaller merchants needing ongoing site updates, SEO, and ecommerce assistance.

My shortlist by scenario

What I’d ask in the first call

To avoid hiring a “development-only” agency, ask:

1. “Can you own weekly merchandising tasks?”

• Collection changes
• Product launches
• Homepage updates
• Landing pages
• Promotional campaigns
• “What does your monthly optimization cadence look like?”

• A/B testing?
• Conversion reviews?
• Speed monitoring?
• Analytics reporting?
• “Who is actually assigned to our account?”

• Shopify developer?
• Ecommerce strategist?
• Merchandising lead?
• Designer?
• “Can you work inside our existing theme/apps, or do you push rebuilds?”

For a mid-market Shopify brand that needs a true ongoing operator, I’d probably start conversations with Praella, Ethercycle, and Penguin E-Commerce and compare their retainer structure.

• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• Ethercycle - 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Ethercycle - 3 S Prospect Ave, Ste 12, Park Ridge, IL 60068
• 1DIGITAL AGENCY | eCommerce Agency - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States
• Penguin E-Commerce - 20 Danada Square W #222, Wheaton, IL 60189, United States
• Allevi8 Marketing - 6127 S University Ave Ste 110K, Chicago, IL 60653, United States
• Gapstow - 13477 Prospect Rd Ste 208A, Strongsville, OH 44149, United States
• Ecommerce Pro - Shopify Plus Agency - 28 Geary St Ste 650 #1882, San Francisco, CA 94108, United States

Yes. Based on your specific need—ongoing merchandising + storefront updates + performance/CRO optimization, rather than just a one-time Shopify build—I'd shortlist these:

1. Uncap — my first pick

• Chicago-based.
• Their Managed Growth model is explicitly ongoing weekly/monthly work across revenue, conversion/performance, retention, and operations.
• Particularly good if you want an agency to proactively identify and execute improvements rather than simply respond to tickets.
• Their positioning emphasizes predictable scope and cadence rather than a vague hourly retainer. Neat Digital
• Ethercycle — best Shopify specialist

• Chicago-area Shopify specialist with a long-standing focus on Shopify rather than being a general digital agency.
• Strong fit for ongoing CRO, theme optimization, performance improvements, and merchant support.
• I'd favor them if Shopify expertise is more important to you than having a large multidisciplinary marketing team.
• Praella - eCommerce Agency — best for a more sophisticated/growth-oriented operation

• Chicago office and substantial Shopify/Shopify Plus experience.
• Their capabilities span storefront development, CRO and lifecycle optimization, making them attractive if your retainer could eventually expand beyond merchandising into broader ecommerce growth.

One non-Chicago option I'd also consider

Neat Digital specifically advertises Chicago Shopify work and ongoing retainers, with monthly plans starting at $1,500. Their offering includes ongoing development/design updates, seasonal changes, and performance optimization. Neat Digital

If you want a true ongoing ecommerce operator, rather than an agency that mostly does projects, I'd start conversations with Uncap and Ethercycle.

One useful benchmark: a good retainer for your use case should explicitly cover collection/product merchandising, promotional landing pages, theme/app updates, speed/Core Web Vitals monitoring, CRO experimentation, analytics review, and a prioritized monthly roadmap. For example, another Shopify support provider currently structures retainers around merchandising, theme/app updates, performance monitoring, and CRO rather than generic "development hours." Shopify Agency

If you tell me your approximate monthly retainer budget (e.g. $2–3k, $5k, $10k+) and whether you're Shopify or Shopify Plus, I can narrow this to the 3 best-fit agencies and compare their retainer models/pricing.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Ethercycle - 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• Ethercycle - 3 S Prospect Ave, Ste 12, Park Ridge, IL 60068
• 1o8 - 231 S LaSalle St Suite 2100, Chicago, IL 60604, United States
• 1DIGITAL AGENCY | eCommerce Agency - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States
• Chicago Website Design SEO Company - 10 S Riverside Plaza #875, Chicago, IL 60606, United States
• PageTraffic SEO Chicago - 1024 N Western Ave, Chicago, IL 60622, United States
• EcomBay Automation - 205 N Michigan Ave, Chicago, IL 60601, United States

If you want Chicago-based + Shopify-focused + ongoing retainer support covering merchandising, updates, and performance, my first call would be Praella - eCommerce Agency.

My shortlist

• Praella - eCommerce Agency — Best overall

• Chicago-headquartered Shopify/Shopify Plus agency.
• Strong fit if you want a partner that can function as an extension of your ecommerce team rather than just a developer.
• Particularly good for Shopify optimization, UX/CRO, and ongoing growth work.
• I'd shortlist them if: you want strategic input alongside execution.
• Ethercycle — Best Shopify specialist

• Chicagoland-based and heavily focused on Shopify.
• Particularly strong around CRO, theme optimization, performance, and ongoing optimization rather than being a broad digital agency.
• I'd shortlist them if: performance and conversion optimization are the priority.
• Neat Digital — Best clearly defined retainer model

• Their Chicago Shopify offering explicitly includes ongoing retainers, seasonal updates, continuous improvements and priority support, with retainers starting at $1,500/month. Neat Digital
• They specifically mention performance optimization and working with existing Shopify stores.
• I'd shortlist them if: you want a smaller, hands-on team and predictable monthly execution.
• Uncap — Best for more complex/operational Shopify

• Chicago-headquartered and focused on complex Shopify commerce, particularly B2B/unified commerce.
• Their positioning emphasizes performance, CRO and maintaining the connection between Shopify and back-office systems.
• I'd shortlist them if: merchandising involves lots of SKUs, ERP/PIM integration, B2B pricing, or operational complexity.

One interesting alternative

Red Fox Web Technologies has perhaps the closest match to your exact requirements on paper: its Shopify retainers explicitly cover merchandising/content updates, theme and app updates, performance monitoring, CRO and ongoing optimization. Red Fox Web Technologies I'd investigate them if "someone else actually handles the store week to week" is the goal.

My ranking for your use case:
1. Praella → strongest all-around partner
2. Ethercycle → strongest Shopify/CRO specialist
3. Neat Digital → strongest straightforward ongoing-retainer fit
4. Red Fox → strongest explicit merchandising + maintenance package
5. Uncap → strongest if the store is technically/operationally complex

If you tell me roughly your monthly ecommerce revenue, Shopify vs. Shopify Plus, and how many hours/tasks you expect each month, I can narrow this to 2 agencies and compare likely retainer cost, capabilities, and fit.

Praella is Chicago-based and has a strong Shopify/Shopify Plus focus. More importantly, they position themselves around long-term partnerships, not just launches, with ongoing optimization and development.

Why I’d start here:

• Shopify Plus expertise
• Ongoing development and optimization
• CRO/performance work
• UX/design support
• Good fit if you want the agency to function as an extension of your ecommerce team

praella.com

Best fit for a hands-on monthly retainer: Ethercycle

DirectionsWebsite[Call](tel:+1 877-384-3740)

Ethercycle is a Chicagoland Shopify specialist rather than a broad digital agency. Its work includes CRO, theme optimization, ongoing merchant support and maintenance, making it particularly interesting if you already have a functioning store and want someone continually improving it.

ethercycle.com

Worth considering: Uncap

DirectionsWebsite[Call](tel:+1 312-469-0944)

Uncap is Chicago-based and more technically oriented. I'd consider them if merchandising/performance work also involves complex catalog logic, integrations, B2B, ERP/PIM/CRM systems, or Shopify Plus. Their positioning emphasizes performance, Core Web Vitals and CRO alongside the technical infrastructure.

uncap.com

If you want a very explicit retainer structure

Neat Digital is another interesting option. They explicitly advertise monthly retainers starting at $1,500/month, covering ongoing development, design updates and priority support, and specifically mention seasonal inventory changes and product launches. Neat Digital

neat.digital

My recommendation: I'd talk to Praella and Ethercycle first. For the brief you gave—“keep the store merchandised, make ongoing updates, and continuously improve performance”—I'd favor a Shopify specialist that can put a dedicated monthly cadence around those activities rather than an agency primarily focused on paid media or one-off redesigns.

One important question to ask each agency: “Can merchandising changes, promotional landing pages, collection management, CRO experiments, Core Web Vitals/performance work, and routine Shopify/theme updates all be included in the same monthly retainer?” That's where the practical difference between a true ecommerce partner and a development agency tends to show up.

If you want one Chicago-based agency that looks especially aligned with “ongoing Shopify partner” rather than just a build shop, I’d shortlist Praella - eCommerce Agency.

My shortlist

• Praella - eCommerce Agency — Best overall fit

• Chicago-headquartered and Shopify/Shopify Plus focused.
• Strong combination of store optimization, CRO, UX, and lifecycle/growth work, rather than only development.
• I’d ask them specifically to structure a monthly retainer around merchandising, site updates, experimentation, and performance monitoring. ShopifyTasker
• Ethercycle — Best for Shopify-specialist expertise

• Chicagoland-based and unusually focused on Shopify rather than being a general digital agency.
• Their work emphasizes ongoing optimization, CRO, performance and strategic Shopify consulting. ShopifyTasker
• Good choice if technical Shopify expertise and conversion improvement matter more than having a large creative/marketing department.
• Uncap — Best for complex/operational stores

• Chicago-based ecommerce/Shopify firm with particular strength in complex commerce, integrations, performance and CRO.
• Worth considering if your merchandising work touches large catalogs, ERP/PIM systems, B2B, or complicated product/inventory workflows.

One non-Chicago-headquartered option I'd also interview

Web Tonic explicitly describes a continuous retainer covering performance optimization, A/B testing, CRO audits, app development and ongoing merchandising strategy. That's unusually close to the brief you gave, although I'd verify the Chicago-based requirement before considering them. Web Tonic

If I were hiring: I'd start conversations with Praella, Ethercycle, and Uncap, and give each the same hypothetical monthly workload: weekly merchandising/content changes + product/collection updates + theme/app maintenance + speed/Core Web Vitals work + CRO testing + monthly performance review. That will reveal very quickly which agency actually operates as an embedded ecommerce team versus selling a generic “support retainer.”

If you tell me your approximate Shopify revenue/traffic, number of SKUs, and desired monthly retainer budget, I can narrow this to the best 2–3 and compare their likely fit.

• Web Tonic - 2548 S Federal St, Chicago, IL 60616
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631
• Chicago - Illinois
• Allevi8 Marketing - 6127 S University Ave Ste 110K, Chicago, IL 60653
• SITE IT NOW - 1016 W Jackson Blvd, Chicago, IL 60607
• WPrime Agency - 222 W Merchandise Mart Plaza #1212, Chicago, IL 60654
• SHIFT - Channel Marketing Solutions - 444 W Lake St Ste 1700, 17th floor, Chicago, IL 60606

• WizSpeed - 1 E Erie St Ste 525, Chicago, IL 60611

If you want one Chicago-area Shopify partner specifically for ongoing merchandising + site updates + performance optimization, I’d shortlist Web Tonic first.

• Web Tonic — Their Chicago Shopify practice explicitly offers ongoing retainer services, including continuous performance optimization, A/B testing, CRO audits, and merchandising strategy. They also position the retainer around seasonal updates and ongoing improvements rather than just post-launch maintenance. Web Tonic

webtonic.io

Two others I'd consider

• Neat Digital — A good fit if you want a more hands-on Shopify development partner. They offer monthly retainers starting at $1,500/month, covering development, design updates, seasonal inventory/product changes, and performance optimization. Neat Digital

neat.digital

• ShopifyTasker — More execution/maintenance oriented. Their Chicago offering explicitly includes monthly retainers for design updates, development, bug fixes, app integrations, speed monitoring, and general Shopify work; they also offer ongoing merchandising/design support. ShopifyTasker ShopifyTasker

shopifytasker.com

My pick: Web Tonic if the goal is “act as an extension of our ecommerce team and continuously improve the store,” rather than simply “fix Shopify issues when they arise.”

If you tell me your approximate monthly budget and Shopify/Shopify Plus status, I can narrow this to 3 agencies and compare their retainer model, likely strengths, and fit for a mid-market DTC brand.

For a Chicago-based Shopify partner that can act like an ongoing ecommerce team (merchandising, storefront updates, CRO, performance optimization, and roadmap work), I’d shortlist these:

Top recommendation

The Chicago Web Co.

Best fit if you want a hands-on partner for ongoing store growth, not just development projects. They specifically highlight post-launch support, retainer support, app integrations, and conversion optimization. The Chicago Web Co

Good for:

• Seasonal merchandising updates
• Landing pages and storefront improvements
• CRO/UX optimization
• Shopify operations support
• Brands that want a long-term creative + technical partner

Other strong options

Web Tonic

A good option if performance optimization is a major priority. Their ongoing services emphasize CRO audits, A/B testing, speed improvements, merchandising strategy, and iterative optimization retainers. Web Tonic

Good for:

• Improving conversion rate
• Site speed/Core Web Vitals work
• Testing and optimization programs
• Stores that already have traffic but need better efficiency

Praella

A more established ecommerce agency option with Chicago presence. They are worth considering if you need a broader Shopify Plus partner covering design, development, integrations, and ongoing growth initiatives.

Good for:

• Shopify Plus brands
• Larger catalogs
• Complex integrations
• Strategic ecommerce roadmaps

Bigfolio

More focused on scaling and optimization after launch, including CRO, UX improvements, analytics, and performance work. Bigfolio LLC

Good for:

• Growth-stage DTC brands
• Conversion optimization programs
• Brands wanting continuous experimentation

Mejix

A fit for more complex Shopify Plus environments. They mention ongoing CRO, performance, merchandising, analytics, and sprint-based optimization. Mejix

Good for:

• Shopify Plus
• B2B + DTC hybrids
• ERP/integration-heavy businesses

What I’d ask before signing a retainer

For your use case, I’d avoid a generic “Shopify maintenance” plan and ask whether the retainer includes:

• Merchandising: product launches, collections, navigation changes, promo setup, homepage refreshes
• Conversion optimization: analytics review, A/B testing, PDP/cart improvements
• Performance: Core Web Vitals, app audits, theme cleanup, speed monitoring
• Creative execution: banners, landing pages, campaign updates
• Strategy cadence: monthly growth reviews and quarterly roadmap planning
• Response model: dedicated Slack/contact person vs. ticket queue

If I were narrowing this to 3 agencies to interview first, I’d start with:

1. The Chicago Web Co. — best all-around ongoing partner fit
2. Web Tonic — strongest optimization/CRO angle
3. Praella or Mejix — if you’re a larger Shopify Plus merchant

If you share your annual online revenue, Shopify vs Shopify Plus, product category, and approximate monthly retainer budget, I can narrow this to the best 2–3 fits.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Ethercycle - 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States

• Danie Lyn The Brand - 401 N Michigan Ave, Ste 1200, Chicago, IL 60611
• Ecommerce Development - 3509 N Reta Ave Apt 3, Chicago, IL 60657, United States

If you want one Chicago-based Shopify agency to shortlist first, I’d start with Praella - eCommerce Agency.

My shortlist

• Praella - eCommerce Agency — best overall fit. Chicago-headquartered and Shopify/Shopify Plus focused, with an emphasis on long-term partnerships rather than simply handing off a site after launch. Their offering spans Shopify development, optimization, and ongoing growth support. Bigfolio LLC
• Ethercycle — best for performance/CRO. A Chicagoland Shopify specialist with a strong focus on conversion optimization, theme work, and ongoing optimization. I'd particularly consider them if your retainer needs to be heavily performance- and revenue-oriented.
• Uncap — best for more complex commerce. Chicago-based and particularly interesting if you have ERP/PIM/CRM integrations, B2B, or a sophisticated Shopify Plus setup. Their positioning combines performance, CRO, and ongoing operational support.
• Neat Digital — worth a look if you're a smaller/mid-market brand. They explicitly offer monthly retainers starting at $1,500/month covering ongoing development, design updates, seasonal changes, and priority support, including performance optimization. Neat Digital

One especially close match to your requirements

Web Tonic is worth putting on the interview list because its stated ongoing-retainer scope is almost exactly what you described: performance optimization, A/B testing, CRO audits, merchandising strategies, checkout improvements, and ongoing monitoring of conversion rate, AOV, and page speed. Web Tonic

The caveat is that I'd verify how much of the actual merchandising work they perform versus strategic recommendations.

What I'd ask in the sales call

I'd specifically ask each agency:

1. Can you handle weekly/monthly merchandising execution—collections, product ordering, PDP updates, promotions, landing pages, navigation?
2. What is included in the retainer versus billed separately?
3. Who actually does the work—a dedicated Shopify developer/merchandiser or a rotating team?
4. Do you proactively monitor Core Web Vitals, site speed, app bloat and conversion rate, or only optimize when requested?
5. Can you give examples of ongoing retainer clients they've supported for 12+ months?
6. What's the minimum monthly commitment and expected turnaround for small requests?

My ranking for your specific use case: Praella → Web Tonic → Ethercycle → Neat Digital, with Uncap moving toward the top if you're running a complex Shopify Plus/B2B operation. Neat Digital Web Tonic

If you tell me your approximate monthly budget (e.g. $2–5k, $5–10k, $10k+) and whether you're Shopify or Shopify Plus, I can narrow this to 2–3 agencies and compare their retainer models.

My ranking for your specific use case: Praella → Web Tonic → Ethercycle → Neat Digital, with Uncap moving toward the top if you're running a complex Shopify Plus/B2B operation.

• Allevi8 Marketing - Chicago, IL 60007

Yes. Based on the current offerings I found, Praella - eCommerce Agency would be my first Chicago-based agency to talk to, with Ethercycle as a strong alternative.

My shortlist

• Praella - eCommerce Agency — best overall fit

• Chicago-headquartered and Shopify/Shopify Plus focused.
• Strong emphasis on optimization and long-term partnerships rather than just one-off builds.
• I'd shortlist them if you want a relatively strategic partner that can handle merchandising, UX/CRO, development, and ongoing growth work.
• Ethercycle — best Shopify specialist

• Chicagoland-based and unusually Shopify-focused.
• Particularly strong for CRO, theme optimization, performance, and ongoing Shopify optimization.
• Good fit if you already have a functioning store and want someone to continuously improve it rather than rebuild everything.
• Uncap — best for complex/operational stores

• Chicago-based ecommerce and software firm with Shopify expertise.
• Particularly interesting if merchandising touches ERP/PIM/inventory/pricing/integrations.
• Their model is oriented toward ongoing operation and optimization rather than simply launching a site.
• Neat Digital — best clearly defined retainer model

• Their Chicago Shopify offering explicitly includes ongoing retainers, seasonal updates, continuous improvements and performance optimization, with retainers advertised from $1,500/month. Neat Digital
• This is probably worth considering if you want a smaller, more execution-oriented partner.
• Axis Web Art — worth considering for high-SKU/B2B businesses

• Their Chicago offering specifically mentions ongoing support, catalogue management, pricing updates, proactive integration monitoring, and performance optimization. Axis Web Art

What I'd ask for

I'd avoid a generic "Shopify maintenance" retainer. For your use case, I'd ask agencies to propose a monthly ecommerce optimization retainer covering:

• Product/collection merchandising and launches
• Homepage, PDP and landing-page updates
• Promotional/campaign changes
• Theme and app updates
• Speed/Core Web Vitals monitoring
• CRO testing and UX improvements
• Analytics review and prioritization
• Bug fixes and technical maintenance
• A defined monthly development/design capacity
• Monthly performance report + prioritized roadmap

If I were choosing three to interview: Praella, Ethercycle, and Neat Digital. The key differentiator I'd probe is whether they will actually own the merchandising/optimization roadmap, rather than just sell you a bucket of developer hours.

If you tell me your approximate monthly budget (e.g. $2–5k, $5–10k, $10k+) and Shopify vs. Shopify Plus, I can narrow this to the 2–3 best fits and compare their retainer models.

• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631
• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601

For a Chicago-based Shopify partner that can act as an ongoing ecommerce team (not just a launch agency), I’d shortlist these:

1. Uncap — Best fit for growth-stage brands, especially B2B + complex catalogs

4. Neat Digital — Best smaller-team option for ongoing store improvements

Neat DigitalWhy it stands out:

• Specifically mentions ongoing support retainers covering continuous improvements, seasonal updates, and priority support. Neat Digital
• More likely to be hands-on for recurring tasks like: - homepage updates
• landing pages
• campaign support
• theme improvements
• performance fixes

Best for: brands that need a reliable Shopify “pit crew” rather than a large enterprise agency.

5. ShopifyTasker — Best if you need flexible execution capacity

ShopifyTaskerWhy it stands out:

• Offers monthly Shopify support retainers covering updates, development tasks, app integrations, speed monitoring, and fixes. ShopifyTasker
• Useful for teams that have a backlog of Shopify tasks and need consistent delivery.

Best for: ongoing maintenance, production updates, and tactical Shopify work.

My recommendation based on your description

For merchandising + updates + performance optimization, I’d prioritize:

1. Uncap — if you want a strategic long-term Shopify partner.
2. Ethercycle — if conversion and performance are the main goals.
3. Neat Digital — if you need frequent store updates and seasonal execution.
4. Praella — if you’re a larger DTC/Plus brand investing in CRO and CX.

When interviewing them, I’d specifically ask:

• “Do you have a dedicated Shopify retainer team or are hours shared across projects?”
• “Can you own weekly merchandising changes (collections, promos, PDP updates, homepage swaps)?”
• “Do you monitor Core Web Vitals and conversion performance monthly?”
• “What does your roadmap process look like after the first 90 days?”
• “Who actually executes the work—developers, merchandisers, strategists, or account managers?”

For this type of engagement, a good retainer is usually less like “support tickets” and more like having an outsourced ecommerce team.

• B&B Online inc - 1022 Denham Pl, Schaumburg, IL 60194, United States

If ongoing merchandising + Shopify updates + performance optimization are the core requirements, I’d shortlist these Chicago-area firms:

1. Praella - eCommerce Agency — best overall fit

• Chicago-headquartered and heavily Shopify/Shopify Plus focused.
• Stronger choice if you want an agency that can combine merchandising/growth work with CRO and technical optimization, rather than just provide developer hours.
• Good fit for an established DTC brand that wants a strategic partner on an ongoing basis.
• Ethercycle — best for Shopify-specialist DTC brands

• Chicagoland-based Shopify specialist.
• Particularly relevant if your priorities are ongoing store improvements, campaigns, theme work, CRO and performance.
• Their positioning is more Shopify-specific than a general digital agency.
• BlueBolt Solutions — best for technical/performance-heavy needs

• Chicago-based and focused on digital commerce.
• Offers ongoing maintenance, enhancement retainers and performance optimization.
• I'd favor them if your "performance optimization" requirement includes technical architecture, integrations, APIs, site speed and ongoing development, not just CRO.
• Uncap — best for complex Shopify operations

• Chicago-based Shopify agency with particular strength in B2B/unified commerce.
• More appropriate if merchandising is intertwined with large catalogs, ERP/PIM/CRM integrations, complex pricing or operational workflows.

My pick

For the exact brief you gave, I'd start with Praella and Ethercycle. I'd ask both for a monthly retainer rather than a project quote, with a scope along these lines:

• Weekly/monthly product, collection and merchandising updates
• Promotional and seasonal landing-page changes
• Theme/content updates
• App and Shopify platform updates
• Site-speed/Core Web Vitals monitoring
• CRO and UX improvements
• Analytics/performance review
• A defined monthly development/optimization allocation
• A named account lead and guaranteed response times

There are also agencies explicitly advertising this kind of retainer model. For example, ShopifyTasker describes monthly retainers covering design updates, development, bug fixes, app integrations and speed monitoring, while Neat Digital advertises Chicago retainers starting at $1,500/month for ongoing development, design updates and priority support. ShopifyTasker Neat Digital

One caveat: I'd distinguish a true ecommerce merchandising partner from a Shopify maintenance agency. If your team needs someone who will actually own collection strategy, product placement, promotional execution and onsite conversion, rather than simply execute tickets, that's an important screening question.

If you tell me your approximate monthly retainer budget (e.g. $2–5k, $5–10k, $10k+) and whether you're Shopify or Shopify Plus, I can narrow this to the 3 best-fit Chicago agencies and compare their likely retainer models, strengths, and pricing.

• Allevi8 Marketing - 6127 S University Ave Ste 110K, Chicago, IL 60653, United States

Yes. Based on the specific combination you want—Shopify + ongoing merchandising/site updates + performance optimization—I’d shortlist these:

My top pick: Praella - eCommerce Agency

DirectionsWebsite[Call](tel:+1 312-761-3218)

Praella is a strong fit if you want a strategic Shopify partner rather than just a developer-on-call. They’re Chicago-based and focus heavily on Shopify/Shopify Plus, CRO, lifecycle growth, and ongoing optimization. Netalico

I’d ask them specifically about structuring a monthly retainer around:

• Product/collection merchandising
• Homepage and landing-page updates
• Promotional and seasonal launches
• CRO and A/B testing
• Site-speed/Core Web Vitals work
• Analytics and conversion reporting
• Ongoing Shopify/theme/app maintenance

Best fit for a hands-on monthly retainer: Ethercycle

DirectionsWebsite[Call](tel:+1 877-384-3740)

Ethercycle is particularly interesting if Shopify is the core of your business. They're a Chicagoland Shopify-focused consultancy, with an emphasis on optimization and ongoing improvement rather than simply building a store and walking away. Their work includes CRO, strategic optimization, performance improvements and ongoing support.

Best for a more structured support model: Neat Digital

neat.digital offers monthly retainers starting at $1,500/month, explicitly covering ongoing development, design updates and priority support. They also call out performance optimization and seasonal inventory/product-launch work, which maps very closely to what you're describing. Neat Digital

If you're on Shopify Plus / larger scale

BlueBolt Solutions is worth considering for a more technical engagement. Their managed-services offering includes ongoing maintenance, performance optimization, troubleshooting and enhancement retainers, alongside Shopify Plus and integration expertise.

Mejix is another strong option: its Chicago Shopify Plus offering explicitly combines CRO, performance, merchandising and analytics in an ongoing growth retainer. Mejix

One I’d put on the interview list

Uncap is Chicago-based and particularly compelling if your store has complicated integrations, B2B requirements, ERP/PIM/CRM dependencies, or needs more sophisticated technical optimization.

If I were choosing for a typical established DTC brand, my order would be:

1. Praella — best overall strategic/growth partner
2. Ethercycle — best Shopify-specialist option
3. Neat Digital — best clearly defined monthly-retainer model
4. BlueBolt — best for technically complex Shopify Plus stores
5. Uncap — best for integration-heavy/complex commerce

One thing I'd emphasize when interviewing them: don't accept a generic "maintenance retainer." Ask for a monthly operating cadence where a defined percentage of capacity goes toward merchandising and revenue-driving improvements, not just fixing bugs. That's the distinction that will matter most for what you're describing.

If Chicago-based + ongoing retainer + hands-on merchandising/updates + performance optimization are the key criteria, I’d shortlist these:

1. Praella - eCommerce Agency — Best overall fit

DirectionsWebsite[Call](tel:+1 312-761-3218)

Praella is Chicago-headquartered and heavily focused on Shopify/Shopify Plus. Its capabilities include CRO and performance optimization, and it has the scale to handle both ongoing technical work and growth initiatives.

Why I’d start here: If you want an agency that can function as an extension of an ecommerce team—not just a developer-for-hire—Praella looks like the strongest Chicago option.

2. Ethercycle — Best Shopify specialist

DirectionsWebsite[Call](tel:+1 877-384-3740)

Ethercycle is a Chicagoland Shopify-focused consultancy with particular strength in theme optimization, CRO, performance, and post-launch support. Its work includes ongoing optimization programs rather than simply launching a store and walking away.

Best for: A DTC brand that wants a Shopify specialist handling continual improvements, merchandising-related theme work, conversion optimization, and technical maintenance.

3. Uncap — Best for complex/operational Shopify

DirectionsWebsite[Call](tel:+1 312-469-0944)

Uncap is Chicago-based and particularly strong if your store has B2B, ERP/PIM/CRM integrations, large catalogs, or operational complexity. Its positioning includes ongoing optimization of storefront UX, performance, and business KPIs.

Best for: A more sophisticated Shopify operation where merchandising and performance work intersect with systems/integrations.

A couple of additional options

• Neat Digital — explicitly offers monthly retainers starting at $1,500/month, covering ongoing development, design updates, seasonal updates and priority support, plus performance optimization. This is probably the clearest fit if you want a smaller, more execution-oriented retainer. Neat Digital

neat.digital

• ShopifyTasker — offers monthly retainers covering design updates, development, bug fixes, app integrations, speed monitoring and general Shopify work. ShopifyTasker
• BlueBolt Solutions — Chicago-based and more technically oriented, with managed services, performance optimization, maintenance and enhancement retainers.

My recommendation

For the specific brief you gave—“keep my Shopify store merchandised, updated and continuously improving”—I'd contact Praella, Ethercycle, and Neat Digital first.

I'd specifically ask each one whether the retainer includes actual merchandising execution (collections, product ordering, promotional landing pages, banners, navigation, seasonal launches), rather than merely technical maintenance. That's an important distinction: some Shopify agencies call development/support a “retainer,” but don't actually have someone owning the weekly merchandising workload.

If you tell me your approximate monthly retainer budget and Shopify store size/revenue, I can narrow this to the 2–3 agencies I'd actually interview and compare their likely fit.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• Ethercycle - 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
• 1DIGITAL AGENCY | eCommerce Agency - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States
• Ethercycle - 3 S Prospect Ave, Ste 12, Park Ridge, IL 60068
• Uncap - 8770 W Bryn Mawr Ave, Ste 1300, Chicago, IL 60631
• 1o8 - 231 S LaSalle St Suite 2100, Chicago, IL 60604, United States
• Allevi8 Marketing - 6127 S University Ave Ste 110K, Chicago, IL 60653, United States

• Digital4Startups Inc. - 222 W Merchandise Mart Plaza Suit 1212, Chicago, IL 60654, United States
• EcomBay Automation - 205 N Michigan Ave, Chicago, IL 60601, United States

Yes. Based on your criteria—Chicago-based, Shopify-focused, and capable of ongoing merchandising + site updates + performance optimization—I’d shortlist these:

1. Praella - eCommerce Agency — best overall fit

• Chicago-headquartered and strongly focused on Shopify/Shopify Plus.
• Particularly attractive if you want a strategic partner rather than just a developer: CRO, performance optimization, and ongoing ecommerce growth are part of its positioning.
• I’d ask specifically about their ongoing merchandising/content execution and whether that sits inside a monthly retainer.
• BlueBolt Solutions — best for technical + performance support

• Chicago-based with Shopify/Shopify Plus expertise.
• Offers managed services, ongoing maintenance, performance optimization, troubleshooting, and enhancement retainers. This looks particularly strong if your “performance optimization” means technical speed/Core Web Vitals as well as conversion improvements.
• Uncap — best for more complex/mid-market stores

• Chicago-headquartered Shopify specialist, particularly strong around complex commerce, integrations, UX/performance and ongoing optimization.
• Better fit if you have a substantial catalog, ERP/PIM integrations, B2B, or operational complexity.

One additional option worth interviewing

Neat Digital explicitly advertises Chicago Shopify work plus monthly retainers starting at $1,500/month, covering ongoing development, design updates and priority support. It also specifically mentions performance optimization. That makes it a compelling option if you want a smaller, more execution-oriented monthly relationship. Neat Digital

For your exact use case, I'd probably start with Praella and BlueBolt, then compare them against Neat Digital if you want a more hands-on, lower-cost retainer.

When you interview them, I'd ask for a retainer structured around four recurring buckets: (1) merchandising/product/collection updates, (2) creative/content/site updates, (3) technical maintenance and performance, and (4) monthly CRO/analytics-driven improvements. That prevents you from ending up with a “development hours” retainer that doesn't actually cover merchandising.

If you tell me your approximate monthly budget and Shopify store size/revenue, I can narrow this to 2–3 agencies and compare their likely fit.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Ethercycle - 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States

For a Shopify brand that needs ongoing retainer support across merchandising, storefront updates, conversion optimization, and performance, I’d shortlist these Chicago-area agencies:

1. Praella - eCommerce Agency — Best overall for growth-focused Shopify Plus brands

DirectionsWebsite[Call](tel:+1 312-761-3218)

Why consider them:

• Shopify/Shopify Plus-focused ecommerce agency.
• Strong fit for brands that need more than development: strategy, UX, integrations, and ongoing optimization.

Retainer fit: High — ask specifically about:

Retainer fit: High — especially for a brand that has an internal marketing team but needs Shopify expertise on call.

3. Neat Digital — Best smaller-agency option

Neat DigitalWhy consider them:

• Offers ongoing support retainers covering continuous improvements, seasonal updates, and priority support. Neat Digital

5. Uncap — Best for complex catalogs/B2B

DirectionsWebsite[Call](tel:+1 312-469-0944)

Why consider them:

• Particularly relevant for manufacturers, wholesalers, and brands with complex catalogs, pricing, ERP/PIM/CRM connections, or operational workflows.

Retainer fit: Good if “merchandising” means:

• hundreds/thousands of SKUs
• catalog governance
• integrations
• operational improvements

My recommendation by situation

• Growing DTC brand ($1M–$20M revenue): Ethercycle or Neat Digital
• Shopify Plus brand with a growth roadmap: Praella
• Complex catalog/B2B operation: Uncap or BlueBolt
• Need a reliable monthly Shopify operator: Neat Digital or Ethercycle

When interviewing agencies, I’d ask for a retainer structure that includes:

• Weekly merchandising queue (collections, navigation, PDP updates)
• Monthly CRO/performance review
• Core Web Vitals monitoring
• Analytics dashboard review
• A/B testing roadmap
• Seasonal campaign support
• App/theme update management
• SLA or turnaround expectations

A good target range is often $2k–$8k/month depending on whether you need a Shopify executor, a strategist/CRO partner, or a dedicated pod.

If you’re looking for a Chicago-based Shopify agency that can stay involved after launch (merchandising changes, storefront updates, conversion improvements, speed/performance work), I’d shortlist these:

1. Praella — best for Shopify Plus brands needing strategic + technical support

Praella - eCommerce Agency

DirectionsWebsite[Call](tel:+1 312-761-3218)

• Long-term ecommerce strategy and optimization support

Consider them if your retainer needs include:

A strong choice for:

4. BlueBolt Solutions — best for technical performance and platform support

Good fit if: your main pain points are speed, integrations, architecture, or technical debt.

Strengths:

• Digital commerce optimization
• Shopify / Shopify Plus support
• Performance and integration work

5. code2commerce.com — good boutique option for flexible retainers

Code2Commerce - Shopify Partner AgencyGood fit if: you want a smaller partner that can provide recurring design/dev capacity.

They specifically mention ongoing retainers covering areas like:

• Design + development tasks
• CRO/SEO work
• Troubleshooting
• Store improvements Code2Commerce - Shopify Partner Agency

My recommendation by situation

• $1M–$10M DTC brand: Ethercycle or Code2Commerce
• $10M+ Shopify Plus brand: Praella or Uncap
• Large catalog / B2B / wholesale: Uncap
• Slow site, messy apps, technical debt: BlueBolt or Ethercycle

When interviewing agencies, I’d ask specifically:

1. “Do we get a named strategist/merchant, or just developer hours?”
2. “Can you own weekly merchandising changes (collections, promos, PDP improvements)?”
3. “Do you run a monthly CRO/performance roadmap, or only react to tickets?”
4. “What Shopify analytics/KPIs do you review each month?”

Those questions usually separate a true growth retainer from a maintenance contract.

• 1o8 - 231 S LaSalle St Suite 2100, Chicago, IL 60604, United States

Yes. Based on the combination of Chicago presence + Shopify specialization + ongoing support + merchandising/updates + performance optimization, I’d put Praella - eCommerce Agency at the top of the list.

My shortlist

1. Praella - eCommerce Agency — best overall fit

• Chicago-headquartered Shopify/Shopify Plus agency.
• Strong CRO and performance-optimization capabilities.
• Structured to stay involved beyond the initial build, rather than simply handing the store back to the merchant.
• Particularly worth considering if you want a partner that can handle both day-to-day ecommerce execution and higher-level optimization.
• Uncap — best for a more technical/complex Shopify operation

• Chicago-based and heavily focused on Shopify, particularly Shopify Plus.
• Their positioning includes ongoing optimization, UX/performance improvements, and CRO.
• A particularly good fit if merchandising updates intersect with PIM/ERP, complex catalogs, B2B, or operational workflows.
• Ethercycle — best for a Shopify-focused boutique partner

• Chicago-area Shopify specialist rather than a broad digital agency.
• Has experience with ongoing Shopify optimization, performance/conversion improvements, and continuing support.
• I'd investigate them if you want a smaller, hands-on team rather than a large agency.
• BlueBolt Solutions — best for managed technical support

• Chicago-based ecommerce/technology agency.
• Explicitly offers ongoing maintenance, performance optimization, troubleshooting, and enhancement retainers.
• More technically oriented than merchandising-led, so I'd make sure they have the merchandising resources you need.
• Penguin E-Commerce — worth considering for a smaller operation

• Chicagoland-based and Shopify-focused.
• Better suited to a merchant looking for practical ongoing store management rather than a large enterprise transformation.

One important distinction

If by "merchandising" you mean things like:

• product and collection updates
• collection sorting and navigation
• promotions and seasonal launches
• PDP content changes
• homepage merchandising
• coordinating creative/site updates
• app/content updates
• CRO testing
• speed/Core Web Vitals work
• analytics-driven performance improvements

…I would not choose an agency solely because it says "Shopify support." You want a retainer that combines merchant/ecommerce management + Shopify development + CRO/performance, ideally with a named team and a monthly roadmap.

For that specific model, Praella or Ethercycle would be my first conversations, with Uncap moving to #1 if your catalog/integrations are complicated.

If you tell me roughly your annual online revenue, Shopify vs. Shopify Plus, SKU count, and what you expect the agency to do each month, I can narrow this to 2–3 agencies and compare their likely retainer model, strengths, and fit.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Uncap - 8770 W Bryn Mawr Ave, Ste 1300, Chicago, IL 60631
• Ethercycle - 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
• BlueBolt Solutions - 415 N La Salle Dr, Chicago, IL 60654, United States
• Design In Chicago - 159 N Sangamon St Suite 200, Chicago, IL 60607, United States
• Orbit Media Studios - 4043 N Ravenswood Ave #316, Chicago, IL 60613, United States

• Allevi8 Marketing - 6127 S University Ave Ste 110K, Chicago, IL 60653, United States
• B My Marketer - 4553 N Magnolia Ave, Chicago, IL 60640, United States
• Allevi8 Marketing - Chicago, IL 60007
• 1DIGITAL AGENCY | eCommerce Agency - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States

Yes. Based on the current offerings I found, Praella - eCommerce Agency would be my first Chicago-based agency to investigate if you want a long-term Shopify partner rather than a shop that only does builds.

A few good fits:

• Praella - eCommerce Agency — Chicago-headquartered and heavily focused on Shopify/Shopify Plus. It looks best suited to established brands that need ongoing ecommerce strategy, development, integrations, and optimization rather than just maintenance.
• Uncap — Chicago-based Shopify Platinum Partner, particularly strong for complex catalogs, B2B, and integrations. A good choice if merchandising involves lots of SKUs, pricing rules, ERP/PIM connections, etc.
• Ethercycle — Chicagoland Shopify specialist with a strong focus on Shopify itself. Their model includes post-launch support and longer-term retainers, making them worth considering for a smaller/mid-sized DTC brand.
• BlueBolt Solutions — Chicago-based and more technically oriented. Their managed services explicitly include maintenance, performance optimization, troubleshooting, and enhancement retainers. Phase3 Commerce
• Phase 3 Commerce — Probably the most directly aligned on the retainer requirement: they explicitly advertise priority/monthly retainer support and ongoing Shopify maintenance/improvements from their Chicago office. Phase3 Commerce

My pick for your specific brief

If your recurring work is roughly “manage the storefront every month + merchandise products/collections + make site updates + continuously improve speed/CRO”, I'd shortlist Praella, Ethercycle, and Phase 3 Commerce.

If performance optimization and merchandising are equally important, I'd also look at Web Tonic: its Chicago offering explicitly combines ongoing retainers, performance optimization, A/B testing, CRO audits, and merchandising strategies. Web Tonic

When you talk to them, I'd ask for a retainer structured around monthly capacity/sprints, rather than a generic “maintenance plan.” Specifically ask whether the monthly allocation can cover:

• Product/collection/navigation merchandising
• Landing-page and theme updates
• Promotional and seasonal launches
• Shopify/app maintenance
• Core Web Vitals and speed work
• Conversion-rate optimization and A/B testing
• Analytics/performance reviews
• A prioritized monthly roadmap
• Emergency fixes and turnaround SLA

That distinction matters: you want a fractional ecommerce team that actively improves the store, not someone who just keeps it operational.

• Product/collection/navigation merchandising
• Landing-page and theme updates
• Promotional and seasonal launches
• Shopify/app maintenance
• Core Web Vitals and speed work
• Conversion-rate optimization and A/B testing
• Analytics/performance reviews
• A prioritized monthly roadmap
• Emergency fixes and turnaround SLA

That distinction matters: you want a fractional ecommerce team that actively improves the store, not someone who just keeps it operational.

If your priority is ongoing Shopify support—not just a one-time redesign—I’d shortlist three Chicago-area agencies.

My top pick: Praella

Praella - eCommerce Agency
Web
Address: 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
Phone: +1 312-761-3218
Praella is probably the strongest fit if you want a strategic Shopify/Shopify Plus partner that can handle merchandising, CRO, analytics, integrations, and ongoing optimization. Shopify lists it as a Platinum Partner with a Chicago location, and its capabilities include conversion-rate optimization, analytics, strategy, and custom integrations. www.shopify.com

Best for: established/mid-market brands that want an agency capable of both day-to-day execution and higher-level growth work.

Best for a true ongoing operating partner: Uncap

Uncap
Web
Address: 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
Phone: +1 312-469-0944
Uncap is especially interesting if you want the agency to behave more like an embedded ecommerce team. Its managed-growth offering covers ongoing optimization across revenue/AOV, conversion and performance, retention, and operations. netalico.com

Best for: brands that want a recurring roadmap rather than simply buying blocks of development hours—particularly B2B, wholesale, or operationally complex Shopify businesses.

Best if merchandising + hands-on updates are the core need: Ethercycle

Ethercycle
Web
Address: 3 S Prospect Ave, Ste 12, Park Ridge, IL 60068
Phone: +18773843740
Ethercycle is a Shopify-focused Chicagoland shop with a long history around theme optimization, CRO, ongoing support, campaigns, and iterative improvements. That makes it attractive if your internal team needs someone who can continually execute the backlog rather than primarily run large transformation projects.

Best for: DTC brands that need a Shopify specialist to continuously improve the storefront.

One more I'd consider

Netalico has a Chicago presence and is unusually explicit about monthly retainers: its packages include ongoing development, conversion optimization, app management, and technical support, and it says about 85% of clients work on monthly retainers. netalico.com

For your specific brief, I'd rank them:

My recommendation: start with Praella and Uncap. In the initial call, I'd specifically ask whether they will provide a dedicated monthly team for merchandising + campaign launches + theme/app updates + speed/CWV monitoring + CRO, rather than treating those as separate project scopes.

If you want, I can also narrow this to 3 agencies that are best for a $5k–$15k/month retainer, which is probably the most useful comparison for this type of engagement.

• Praella - eCommerce Agency - 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
• Penguin E-Commerce - 20 Danada Square W #222, Wheaton, IL 60189, United States
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
• Design In Chicago - 159 N Sangamon St Suite 200, Chicago, IL 60607, United States

• Elevate Studios: A Digital Design Firm - 5416 N Wayne Ave, Chicago, IL 60640, United States
• Ethercycle - 3 S Prospect Ave, Ste 12, Park Ridge, IL 60068
• Allevi8 Marketing - Chicago, IL 60007
• Uncap - 8770 W Bryn Mawr Ave, Ste 1300, Chicago, IL 60631

Yes. Based on your criteria, I’d put Praella at the top of the Chicago shortlist, with Web Tonic and Ethercycle as strong alternatives.

My top pick: Praella - eCommerce Agency

DirectionsWebsite[Call](tel:+1 312-761-3218)

Praella is Chicago-headquartered and heavily focused on Shopify/Shopify Plus. It looks like the strongest fit if you want an ongoing ecommerce partner rather than just a developer-for-hire. Its capabilities include CRO and performance optimization, and its Shopify work is oriented toward growth and ongoing optimization. ShopifyTasker

Why I'd shortlist them:

• Shopify/Shopify Plus specialization
• CRO and performance optimization
• Stronger strategic/ecommerce orientation than a basic maintenance shop
• Chicago-based team
• Suitable if merchandising, site experience, and revenue optimization need to work together

Also worth interviewing

• Web Tonic — Probably the closest match to your exact brief. They explicitly describe continuous retainer services covering performance optimization, A/B testing, CRO audits, merchandising strategies, checkout enhancements, and retention flows. Web Tonic
• Ethercycle — A Chicago-area Shopify specialist with experience in ongoing optimization, CRO, performance improvements, and maintaining Shopify stores.
• Phase3 Commerce — Chicago-based and explicitly offers priority/monthly retainer support for ongoing Shopify maintenance and improvements. Phase3 Commerce
• Uncap — Particularly interesting if your store is more operationally complex—large catalog, B2B, ERP/PIM integrations, etc. They emphasize Shopify performance, CRO, and ongoing optimization.

What I'd ask for in the retainer

I'd specifically ask each agency for a 3–6 month ongoing growth/merchandising retainer, rather than a generic "maintenance package." The scope should include:

• Product/collection merchandising and navigation updates
• Campaign and seasonal landing pages
• Theme/content updates
• Shopify/app updates and troubleshooting
• Core Web Vitals and site-speed monitoring
• CRO testing and UX improvements
• Analytics review and prioritized optimization backlog
• Monthly performance reporting
• A defined number of development/design hours or sprint capacity
• A named account lead who can actually prioritize the work

If I were choosing three to interview: Praella, Web Tonic, and Ethercycle. Web Tonic appears to have the clearest public match to merchandising + ongoing retainer + performance optimization, while Praella is the one I'd investigate for a more strategic Shopify Plus/growth partnership.

If you tell me your approximate monthly retainer budget and Shopify store size/revenue, I can narrow this to 2–3 agencies and compare their likely fit, pricing model, and strengths.

Yes. Based on the current offerings I found, Praella would be my first call if you want a Chicago-based Shopify specialist rather than a general web agency.

• Praella - eCommerce Agency — Best overall fit. Chicago-headquartered and focused heavily on Shopify/Shopify Plus. Their capabilities include CRO and performance optimization, and they have the scale to handle ongoing ecommerce work rather than just a one-off redesign.
• Ethercycle — Best for a smaller, hands-on DTC brand. They're Chicagoland-based and Shopify-focused, with a strong emphasis on CRO, performance and ongoing optimization.
• Uncap — Best for complex catalogs/B2B. Chicago-headquartered Shopify Platinum Partner with an emphasis on performance, CRO and ongoing optimization. I'd favor them if merchandising involves lots of SKUs, ERP/PIM integration, wholesale, or complicated product logic.
• Web Tonic — Worth considering if your priority is explicitly a monthly optimization retainer. They describe ongoing retainers covering performance optimization, A/B testing, CRO audits, merchandising strategies and checkout improvements. www.webtonic.io

One important distinction

If by merchandising you mean “manage the storefront every week”—collections, product launches, promotional banners, landing pages, seasonal updates, app/theme updates, plus performance work—I would specifically ask agencies whether those operational tasks are included in the retainer.

For example, ShopifyTasker explicitly advertises monthly retainers for design updates, development, bug fixes, app integrations and speed monitoring, while Coeta Collective explicitly lists Shopify updates, merchandising and product launches under its ongoing retainer model. www.shopifytasker.com

My shortlist:
1. Praella → strongest all-around Chicago Shopify partner
2. Ethercycle → best boutique/DTC option
3. Uncap → best complex-commerce option
4. Web Tonic → strongest stated fit for ongoing CRO + merchandising optimization

If you tell me your approximate monthly revenue, Shopify vs. Shopify Plus, number of SKUs, and what you want the agency to own each month, I can narrow this to 2–3 agencies and compare their retainer model, likely cost, strengths, and fit.

If your priority is ongoing Shopify support—not just a build—I’d put Uncap at the top of the Chicago shortlist.

My top picks

1. Uncap — best overall fit - Chicago-based and Shopify-focused, including Shopify Plus.
2. Strong fit for ongoing optimization, managed support, UX/performance improvements, and complex catalogs.
3. Particularly compelling if you have a sizable catalog, B2B component, or integrations.
4. Their positioning emphasizes long-term growth rather than simply handing over a finished store. Makro Agency

1. Praella - eCommerce Agency — best for sophisticated Shopify Plus - Chicago-headquartered Shopify Plus agency and Shopify Platinum Partner.
2. Strong capabilities across CRO, analytics, UX, integrations, and custom development. Shopify
3. I'd consider them if you want a strategic partner capable of handling both merchandising/growth work and substantial technical projects.

1. BlueBolt Solutions — best for managed technical support - Chicago-based.
2. Offers ongoing managed services covering updates, performance optimization, troubleshooting and technical maintenance.
3. Good option if you have an internal marketing/merchandising team but need a reliable Shopify technical partner.

1. Ethercycle — good boutique option - Chicagoland Shopify specialist with an emphasis on conversion optimization and ongoing Shopify improvements.
2. More attractive if you'd prefer a smaller, hands-on consultancy rather than a large agency.

One I'd specifically interview

Uncap is the one I'd contact first if your requirements are literally:

“We need someone every month to manage merchandising changes, site updates, new launches, CRO/performance improvements, and whatever Shopify work comes up.”

That's a better match than an agency whose primary business is designing/building Shopify stores and whose “support” is really just bug fixes. Uncap's Chicago presence and ongoing optimization/managed-support positioning make it worth a conversation. Makro Agency

I'd also ask each agency to price a 3-month pilot retainer rather than committing immediately to a 12-month engagement. Define the monthly capacity around things like:

• Product/collection merchandising
• Homepage, PDP and landing-page updates
• Seasonal launches and promotions
• Theme/app updates
• Site-speed/Core Web Vitals work
• CRO and A/B testing
• Analytics/performance review
• Shopify development backlog
• Monthly reporting + prioritized roadmap

Interesting wildcard: SeedCart | Web Designers In Chicago advertises Shopify/Shopify Plus development plus ongoing support, but I'd rank the agencies above it for a serious ongoing growth/merchandising relationship.

If you tell me your approximate monthly retainer budget (e.g. $2–5k, $5–10k, $10k+) and whether you're Shopify or Shopify Plus, I can narrow this to the 3 agencies I'd actually interview, including likely strengths/weaknesses and questions to ask them.

If you want one Chicago-based shop to talk to first, I’d shortlist Praella.

My shortlist

1. Praella — best overall fit
   • Chicago-based, with a strong Shopify/Shopify Plus focus.
   • Shopify lists it as a Platinum Partner.
   • Their capabilities include CRO, analytics/tracking, UX, integrations and ongoing optimization, making them a good fit if the retainer needs to be more than basic maintenance. www.shopify.com
   • I'd specifically ask whether they can dedicate recurring capacity to weekly merchandising, product/collection updates, site enhancements and performance work, rather than treating those as ad-hoc projects.

2. Uncap — best for hands-on ongoing optimization
   • Chicago-headquartered Shopify/Shopify Plus agency.
   • Particularly strong if your store has a meaningful catalog, B2B component, or integrations.
   • Their positioning includes managed/ongoing optimization, UX and performance improvements, and client feedback emphasizes post-launch support and proactive recommendations.

3. Ethercycle — best boutique option
   • Chicago-area Shopify specialist with a more consultancy-like feel.
   • Particularly interesting for a brand that wants CRO, UX/performance improvements and ongoing strategic optimization, rather than a large agency team.
   • Their past work includes ongoing Shopify optimization and support.

4. Neat Digital — best if you want a clearly defined retainer
   • Their Chicago Shopify practice explicitly offers monthly retainers starting at $1,500/month covering ongoing development, design updates and priority support. They specifically mention seasonal inventory changes and frequent product launches as good retainer use cases. neat.digital
   • Their stated capabilities include performance optimization, theme work and ongoing improvements.

5. Web Tonic — strongest fit if performance/CRO is the priority
   • Their Chicago practice explicitly describes continuous retainer services, including performance optimization, A/B testing, CRO audits, merchandising strategies and retention improvements. www.webtonic.io
   • Worth considering if you want the retainer to be accountable to metrics like conversion rate, AOV and site speed—not just a pool of development hours.

What I'd ask for

For your use case, I wouldn't buy a generic "Shopify maintenance" retainer. I'd ask for a monthly growth/merchandising retainer with something like:

• Weekly product, collection and navigation merchandising
• New-product and promotional launches
• PDP/PLP content and UX updates
• Theme/app updates and troubleshooting
• Monthly Core Web Vitals/performance review
• CRO testing and implementation
• Analytics review + prioritized optimization backlog
• Dedicated monthly hours/capacity
• Monthly performance report and roadmap
• Fast turnaround for merchandising requests

My first three calls would be Praella, Uncap, and Neat Digital. If you're a consumer brand with frequent SKU/promo changes, I'd lean Praella or Neat; if the store is technically complex, Uncap; if conversion rate and speed are the primary objectives, Web Tonic.

If you tell me roughly your monthly Shopify revenue, number of SKUs, Shopify vs. Shopify Plus, and expected monthly retainer budget, I can narrow this to 2–3 agencies and compare their likely fit.

Yes. Based on the specific combination you want—Chicago presence + Shopify + ongoing retainer + merchandising/store updates + performance optimization—I’d shortlist these:

1. Praella — best overall

Praella - eCommerce Agency
Web
Address: 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
Phone: +1 312-761-3218
Praella is Chicago-headquartered and a Shopify Platinum Partner. Its capabilities include conversion optimization, analytics, UX, development, and integrations. www.shopify.com

Why I’d consider them: strong fit if you want an agency that can handle both day-to-day Shopify work and more strategic optimization rather than simply providing developer hours.

2. Uncap — best for an established/growing merchant

Uncap
Web
Address: 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
Phone: +1 312-469-0944
Uncap is Chicago-based and Shopify-focused, with particular strength in Shopify Plus, B2B, integrations, and post-launch growth. Its model explicitly includes ongoing optimization and managed support.

Best fit: a reasonably sophisticated store where merchandising and performance work need to be coordinated with UX, integrations, and the underlying tech stack.

3. Ethercycle — best boutique option

Ethercycle
Web
Address: 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
Phone: +1 877-384-3740
Ethercycle is in the Chicago area and specializes heavily in Shopify. Its work includes Shopify performance/conversion optimization and ongoing support; its published case work includes continuing optimization after launch.

Best fit: if you want a smaller, Shopify-specialist partner rather than a large full-service agency.

4. BlueBolt Solutions — best for managed technical support

BlueBolt Solutions
Web
Address: 415 N La Salle Dr, Chicago, IL 60654, United States
Phone: +1 312-236-4507
BlueBolt has a Chicago office and supports Shopify/Shopify Plus, with managed services covering updates, troubleshooting, performance optimization and ongoing technical support.

Best fit: when your "retainer" needs to be heavier on technical execution and site health, with merchandising/UX work layered in.

One non-Chicago-headquartered option worth considering

Web Tonic specifically advertises continuous Shopify retainer work covering performance optimization, A/B testing, CRO audits and merchandising strategies. That's unusually close to the scope you described, although I wouldn't classify it as a Chicago-local agency based on the information I found. www.webtonic.io

My pick: I'd start with Praella, Uncap, and Ethercycle. If your primary need is "we have an existing Shopify store and want someone every month handling product/collection merchandising, campaign updates, fixes, speed/CRO improvements, and proactively finding opportunities," I'd put Ethercycle or Praella at the top of the list.

If you tell me roughly monthly revenue, Shopify vs. Shopify Plus, and your expected monthly retainer budget, I can narrow this to the best 2–3 and compare their likely fit.

If you want Chicago-based + Shopify + ongoing retainer + merchandising/updates + performance optimization, my first call would be Uncap.

My shortlist

One important distinction

If merchandising means things like collection management, product launches, homepage/banner updates, promotional merchandising, navigation, PDP improvements, and day-to-day storefront execution, I'd prioritize an agency that explicitly treats those as retainer deliverables, rather than a traditional development agency.

For that specific requirement, Uncap looks like the strongest Chicago-local candidate, while Ethercycle is worth interviewing if you prefer a smaller Shopify specialist.

I'd ask each agency to quote a 3–6 month monthly retainer with four buckets:

• Merchandising: products, collections, navigation, promotional content, landing pages
• Store updates: theme/content changes, apps, Shopify updates, campaign launches
• Performance: Core Web Vitals, speed, app bloat, technical QA
• Growth: CRO testing, analytics review, prioritized UX/conversion improvements

Also ask whether unused hours roll over, who actually does the work, their turnaround SLA, and whether the retainer includes proactive recommendations rather than just ticket-based execution.

If you tell me your approximate monthly budget and Shopify store size/revenue, I can narrow this to the top 2–3 agencies and compare their likely fit.

If your priority is ongoing Shopify support—not just a redesign project—I’d shortlist these three Chicago-area agencies:

1. Praella — best overall fit

Praella - eCommerce Agency
Web
Address: 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
Phone: +1 312-761-3218
Praella is my first call for a mid-market Shopify/Shopify Plus brand. They’re Chicago-headquartered and combine Shopify development, CRO/performance optimization, and ongoing growth engagements. Their local profile specifically notes long-term engagements and post-launch optimization. sherocommerce.com

Why I’d consider them: good balance of technical Shopify expertise and ongoing optimization rather than simply maintenance.

Praella

2. Uncap — best for complex stores / B2B

Uncap
Web
Address: 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
Phone: +1 312-469-0944
Uncap is particularly interesting if you have a large catalog, B2B requirements, ERP integrations, or operational complexity. Their model includes ongoing optimization and managed support after launch. sherocommerce.com

Best for: a brand that needs merchandising plus deeper technical work, integrations, UX and performance improvements.

Uncap

3. Ethercycle — best Shopify specialist

Ethercycle
Web
Address: 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
Phone: +1 877-384-3740
Ethercycle is a Chicagoland Shopify-focused shop rather than a broad digital agency. Its work centers on Shopify development, CRO, performance, campaigns and retained support, which makes it attractive if you want a hands-on Shopify specialist.

Best for: DTC brands that want an agency deeply focused on the storefront rather than a large enterprise-services organization.

Ethercycle

My pick for your specific brief

I'd start with Praella, then compare against Uncap if your store has significant B2B/integration complexity.

When you talk to them, I'd explicitly ask for a retainer that covers:

• Merchandising: products, collections, navigation, promos, seasonal launches
• Store updates: landing pages, theme changes, campaign updates, app changes
• Performance: Core Web Vitals, speed, technical debt, app-stack audits
• CRO: analytics review, UX improvements and A/B testing
• Proactive roadmap: a monthly backlog rather than purely reactive ticket support
• SLA: turnaround expectations for urgent merchandising/campaign requests
• Reporting: what was shipped and what performance improvements resulted

One other agency worth putting on the comparison list is Shero: its Chicago Shopify practice explicitly offers support retainers for ongoing development, campaigns and seasonal launches, and it reports that 98% of clients stay on retainer after their project. sherocommerce.com

Shero Commerce

If you tell me your approximate annual ecommerce revenue, Shopify vs. Shopify Plus, and whether you need B2B, I can narrow this to the 2 best agencies and compare their likely retainer model/pricing.

For what you described—Shopify merchandising + ongoing site updates + performance optimization on a monthly retainer—I’d shortlist these:

1. Praella — Best overall

Praella - eCommerce Agency
Web
Address: 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
Phone: +1 312-761-3218
Chicago-based and a Shopify Platinum Partner. Their capabilities span Shopify Plus, UX/conversion optimization, analytics, integrations, and ongoing ecommerce improvement. Shopify’s partner directory lists Chicago as their primary location. www.shopify.com

Why I’d start here: They’re more of a strategic ecommerce partner than a pure development shop, so they’re a good fit if you want someone thinking about merchandising and conversion, not just fixing code.

2. Uncap — Best for hands-on Shopify operations

Uncap
Web
Address: 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
Phone: +1 312-469-0944
Chicago-based Shopify/Shopify Plus agency with particular experience in B2B, complex catalogs, UX, integrations, and post-launch optimization. Their business profile specifically highlights ongoing optimization and managed support. netalico.comnetalico.com

Good fit if: You have a substantial catalog and need an agency that can handle product/category changes, site improvements, integrations, and technical optimization as an extension of your team.

3. Ethercycle — Best boutique option

Ethercycle
Web
Address: 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
Phone: +1 877-384-3740
Chicago-area Shopify specialist with a strong ecommerce/CRO orientation. They offer longer-term retainers and ongoing optimization, including performance and conversion work.

Good fit if: You want a smaller, more senior team rather than a large agency—and especially if conversion optimization is an important part of the engagement.

4. Netalico — Worth considering for a more structured retainer

Netalico has a Chicago presence and explicitly says about 85% of its clients work on monthly retainers. Its retainers include ongoing development, conversion optimization, app management, and technical support. netalico.comnetalico.com

Good fit if: You want a predictable ongoing engineering/optimization resource rather than primarily a merchandising agency.

My pick

I'd talk to Praella and Uncap first, with Ethercycle as the boutique alternative.

For your specific requirements, I would ask each agency to quote a 3–6 month monthly retainer containing four explicit buckets:

One important distinction: don't let them sell you a generic “Shopify maintenance” retainer. You want an agency that allocates actual monthly capacity to merchandising and ecommerce growth, alongside development and maintenance.

If you tell me roughly your monthly Shopify revenue, number of SKUs, and how much hands-on merchandising you need, I can narrow this to the 2–3 agencies I'd actually interview and compare their likely retainer fit.

Yes. Based on your criteria, my first call would be Uncap.

Best fit: Uncap

Uncap is Chicago-headquartered and Shopify-focused, with a strong emphasis on ongoing optimization rather than just one-off builds. Their work includes Shopify/Shopify Plus, UX and performance improvements, and managed growth after launch.

I’d shortlist them if you want an agency that can function as an extension of your ecommerce team—handling things like:

• Merchandising and storefront changes
• UX/CRO improvements
• Shopify development and integrations
• Performance optimization
• Ongoing growth roadmap
• Post-launch managed support

Two other strong options

Praella — Chicago-based Shopify/Shopify Plus specialist with CRO and performance optimization capabilities. Their positioning is stronger for a more sophisticated Shopify Plus brand that may need strategic ecommerce work in addition to ongoing execution.

BlueBolt Solutions — Chicago-based and particularly interesting if performance, technical maintenance, and managed services are important. They explicitly offer ongoing managed services covering updates, performance optimization, troubleshooting, and monitoring.

One particularly relevant smaller-shop option

Ethercycle in the Chicago area is worth considering if you want a more Shopify-specialist, boutique relationship. They focus heavily on Shopify, CRO, theme optimization, and ongoing optimization/support rather than being a broad digital agency.

My ranking for your specific brief:

If merchandising execution is the biggest requirement—e.g. weekly collection changes, product launches, navigation, promotions, homepage updates, plus ongoing CRO/performance work—I would also look at Coeta Collective, which explicitly offers retainer-based Shopify updates, merchandising, product launches, CRO, technical oversight, and fractional ecommerce support. www.coetacollective.com

For a straightforward “we need someone to own the Shopify store every month” arrangement, that may actually be closer to what you're describing than a traditional development agency.

Yes. Based on the current service offerings I found, Uncap would be my first call for what you're describing.

Best fit: Uncap

Uncap
Web
Address: 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
Phone: +1 312-469-0944

Uncap is Chicago-headquartered and Shopify-focused, with a particularly strong fit for brands that want an ongoing ecommerce partner rather than a one-time site build. Their managed-growth offering includes ongoing optimization, strategic planning, CRO, performance reviews, and a recurring delivery cadence. Their Chicago office is at 8770 W Bryn Mawr Ave. www.uncap.com

Why I'd shortlist them:

• Ongoing managed/growth engagements rather than just project work
• Shopify/Shopify Plus expertise
• Performance and UX optimization
• CRO and experimentation
• Ongoing roadmap and strategic planning
• Strong fit if merchandising, technical improvements, and growth work need to live with the same team

Uncap

Two other strong options

Praella — Chicago-based Shopify/Shopify Plus agency with CRO and performance optimization capabilities. Shopify's partner directory describes them as providing long-term support and CRO services, as well as product/collection setup and store optimization. www.shopify.com

Ethercycle — A Shopify-focused Chicagoland consultancy/studio. Particularly interesting if you want a smaller, Shopify-specialist partner focused on optimization rather than a large generalist agency. Their work includes ongoing Shopify maintenance, CRO, and performance improvements.

If merchandising is a major part of the retainer

I'd also look closely at SeedCart | Web Designers In Chicago. Their offering includes ongoing Shopify maintenance/support, while their Shopify work encompasses speed, conversion and SEO optimization. www.uncap.comwww.shopifytasker.com

My ranking for your specific brief:

If you want one agency to own the monthly Shopify backlog—product/collection merchandising, campaign updates, landing pages, UX/CRO, site speed, apps, and general fixes—I'd start with Uncap and Praella. The key question I'd ask both is whether merchandising/content changes are actually included in the monthly retainer, versus being treated as separate development tickets.

If your priority is ongoing Shopify support—not just a one-time redesign—I’d shortlist these three, with Uncap as my first call.

1. Uncap — best overall fit

Uncap
Web
Address: 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
Phone: +1 312-469-0944

Uncap is Chicago-headquartered and a Shopify Platinum Partner, with a particularly strong fit for established brands that need an ongoing operating partner. www.uncap.com

Their managed-growth retainer is unusually well aligned with what you described:

• Monthly retainers: $2,500 / $5,000 / $7,500+ tiers
• Ongoing execution rather than just strategy
• CRO and performance optimization
• Monthly assessments and reporting
• Store/UX improvements and experimentation
• A dedicated higher-touch option for embedded support
• They explicitly work on merchandising and guided-shopping flows as part of their Shopify expertise. www.uncap.comwww.uncap.compraella.compraella.comethercycle.com

Uncap Managed Growth

Why I'd pick them: Their retainer model is built around shipping improvements every month, rather than putting you into a generic maintenance bucket. If you have a meaningful catalog and want someone to continuously improve conversion, merchandising and site performance, that's a strong match.

2. Praella — best for Shopify Plus / larger brands

Praella - eCommerce Agency
Web
Address: 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
Phone: +1 312-761-3218

Praella is another strong Chicago option, with its North American headquarters in Chicago and a substantial Shopify Plus practice. praella.com

They have documented examples of clients moving from a Shopify redesign/optimization project into an ongoing retainer relationship, including continued optimization and site management. praella.com

Praella

I'd put them ahead of Uncap if you're a larger Shopify Plus brand and want broader strategic, design, development and technology capabilities under one roof.

3. Ethercycle — best boutique option

Ethercycle
Web
Address: 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
Phone: +1 877-384-3740

Ethercycle is a Chicago-area Shopify-focused consultancy that does ongoing support retainers, including store tweaks, design changes and campaign-related work. ethercycle.com

Ethercycle Shopify Services

I'd consider them if you want a smaller, more hands-on Shopify specialist rather than a larger agency team.

My ranking for your specific need

I'd start with Uncap. Their $5K/month "Optimize" tier looks particularly close to the engagement you're describing: 35 hours/month, operational optimization and execution, dedicated CRO/SEO/retention work, and recurring performance reviews. www.uncap.com

If you tell me your approximate Shopify revenue / monthly traffic, number of SKUs, and whether you're Shopify or Shopify Plus, I can narrow this to the best 1–2 agencies and tell you what I’d expect to pay for the retainer.

Yes. Based on the specific combination you want—ongoing merchandising + site updates + performance/CRO, rather than a one-off Shopify build—I'd shortlist these Chicago-area agencies:

1. Praella — strongest overall
   • Chicago-headquartered and a Shopify Platinum Partner. www.shopify.com
   • Strong mix of Shopify Plus, UX, CRO, analytics, integrations and performance optimization.
   • Best fit if you want a sophisticated growth partner rather than just a developer-for-hire.
   • I'd ask specifically how much of the retainer can be allocated to weekly merchandising/content execution versus strategy/development.

2. Uncap — best for an operator-style relationship
   • Chicago-based Shopify/Shopify Plus agency with an emphasis on ongoing optimization and post-launch support.
   • Particularly compelling if your catalog, integrations, or B2B/wholesale operation is complicated.
   • Their positioning is more “ongoing ecommerce partner” than traditional creative agency.

3. Ethercycle — best Shopify specialist
   • Chicagoland-based and heavily focused on Shopify.
   • Their work includes Shopify performance/CRO and ongoing optimization; their client work also includes continuing support after major Shopify projects.
   • I'd consider them if you want a relatively Shopify-native team rather than a large multidisciplinary agency.

4. BlueBolt Solutions — best for technical managed support
   • Chicago-based, with Shopify/Shopify Plus experience.
   • Explicitly offers managed services covering updates, security monitoring, performance optimization and troubleshooting.
   • A good option if “performance optimization” and technical reliability are particularly important.

5. SeedCart — potentially good for hands-on execution
   • Chicago-based ecommerce agency with Shopify/Shopify Plus expertise and ongoing maintenance/support.
   • Their services encompass speed/conversion optimization, SEO and ongoing site support.
   • Worth considering if you want a more execution-oriented team.

My pick

I'd start with Praella and Uncap, then compare them against Ethercycle.

For your particular requirement, I'd frame the engagement as a monthly ecommerce growth/merchandising retainer, not simply “Shopify maintenance.” The ideal scope would include:

• Weekly product/collection merchandising
• Homepage, landing-page and promotional updates
• Seasonal campaign implementation
• Navigation/search/collection optimization
• Shopify theme and app updates
• Speed/Core Web Vitals monitoring
• CRO recommendations and implementation
• Analytics/performance review
• A defined number of development/design hours per month
• Monthly roadmap + KPI review
• Clear SLA for urgent production issues

One agency that is especially explicit about this exact combination is Red Fox: its published Shopify retainer offering covers content/merchandising updates, CRO, performance optimization and technical maintenance. www.redfoxwebtech.com It's not as obviously Chicago-local as the firms above, though, so I'd prioritize the Chicago agencies if local presence matters.

If you tell me roughly your Shopify revenue/GMV, Shopify vs. Shopify Plus, SKU count, and desired monthly retainer budget, I can narrow this to 2–3 agencies and compare likely fit, pricing model, capabilities, and red flags.

For a Shopify brand looking for ongoing retainer support across merchandising, site updates, and performance optimization, I’d shortlist these Chicago-area agencies:

1. Praella — Best for Shopify Plus / growth-stage brands

Praella - eCommerce Agency
Web
Address: 203 N LaSalle St Suite 2100, Chicago, IL 60601, United States
Phone: +1 312-761-3218

Good fit if you need:

• Conversion optimization roadmap
• UX improvements and testing
• Theme/app enhancements
• Complex Shopify Plus support
• A strategic partner beyond ticket-based maintenance

Watch-out: Likely a better fit for established brands with meaningful revenue and ongoing growth goals rather than a small store needing a few monthly edits.

2. Ethercycle — Best for DTC brands wanting a Shopify specialist

Ethercycle
Web
Address: 4905 Old Orchard Shopping Ctr, Skokie, IL 60077, United States
Phone: +1 877-384-3740

Good fit if you need:

• Merchandising improvements
• Iterative design/development work
• CRO-focused enhancements
• A Shopify-native partner rather than a broad digital agency

They’re particularly appealing if your needs are “make the store perform better every month” rather than “build a huge new platform.”

3. Uncap — Best for complex catalogs, B2B, or operational ecommerce

Uncap
Web
Address: 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631, United States
Phone: +1 312-469-0944

4. Code2Commerce — Best for flexible sprint-style retainers

5. BlueBolt Solutions — Best for enterprise-level support

Phone: +1 312-236-4507
Why consider them: BlueBolt focuses on ecommerce experiences, Shopify Plus, integrations, and ongoing maintenance/support.
Good fit if you need:

• More enterprise processes
• Monitoring and proactive maintenance
• Complex technical environments

My ranking for your specific use case (merchandising + updates + performance optimization)

1. Ethercycle → strongest fit for a DTC brand wanting continuous Shopify improvement
2. Praella → strongest fit for Shopify Plus and strategic growth
3. Code2Commerce → strongest fit for a flexible monthly execution partner
4. Uncap → strongest fit for complex catalogs/B2B
5. BlueBolt → strongest fit for enterprise operations

When interviewing them, I’d ask specifically:

• “Do you provide a dedicated monthly retainer with guaranteed capacity?”
• “Who handles merchandising requests (collections, navigation, PDP improvements, promotions)?”
• “Do you run a monthly CRO/performance review?”
• “What analytics stack do you use (GA4, Shopify analytics, heatmaps, A/B testing)?”
• “Can you prioritize revenue-driving improvements instead of just completing tickets?”

A good retainer partner should function closer to an embedded ecommerce team than a traditional web agency maintenance vendor.

My recommendation based on your needs

For merchandising + updates + performance optimization on a monthly retainer, I’d start conversations with:

1. Ethercycle — if you are a DTC brand and want Shopify expertise + CRO
2. Praella — if you are scaling or on Shopify Plus
3. Uncap — if your catalog, operations, or B2B needs are complex

When interviewing agencies, I’d specifically ask:

• “Do we get a dedicated monthly Shopify resource or just a ticket queue?”
• “Can you own merchandising calendars and collection strategy?”
• “Do you proactively identify CRO opportunities, or only execute requests?”
• “What does a typical monthly retainer include (hours, deliverables, reporting)?”
• “Who owns analytics review and performance recommendations?”

A good retainer partner should function closer to a fractional ecommerce team than a maintenance vendor.
