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

• Theme/app enhancements

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.
