If by “separate programs per store” you mean you manage multiple clients, and each Shopify store needs its own independent marketing/loyalty/automation program, I’d prioritize software that supports multiple independent accounts/tenants under one agency login.

A key distinction: Shopify itself can group multiple stores and provide centralized user management, but the stores still have their own settings, data, and configurations. On Shopify Plus, expansion stores remain operationally independent, and apps are generally billed per store. Shopify Help Center Shopify Help Center

What I’d look for

• Multi-account/agency management — one login, easy switching between clients.
• True account separation — customers, campaigns, automations and reporting don't accidentally mix.
• Per-store billing — each client can pay for their own program.
• Client permissions — you can manage the account without giving clients access to other stores.
• Shopify-native integration — ideally a direct Shopify app rather than a complicated middleware setup.
• Agency/portfolio reporting — useful if you want a dashboard across all clients without merging their data.

For example, Klaviyo explicitly supports multiple accounts under one login, with each ecommerce store generally using its own Klaviyo account. It also has portfolio functionality for viewing multiple accounts together. Klaviyo Help Center

Shopify has also improved its own partner organization/RBAC system in 2026, including roles that can be scoped to particular stores, which is useful if your team is managing client stores. shopify.com

But I can give you a much more specific recommendation if you tell me what “programs” means in your case — e.g. loyalty/rewards, email/SMS, affiliate/referral, subscriptions, memberships, customer retention, or something else. The best platform changes substantially depending on that.

If by “separate programs per store” you mean you manage multiple clients, and each Shopify store needs its own apps/automation/programs without mixing data, I’d structure the stack around Shopify’s multi-store model rather than looking for one giant platform.

My recommendation

Use Shopify Partner/Organization management as the base, then choose software that supports multiple independent store accounts.

Shopify now lets organizations group multiple stores, with store-level permissions and app permissions so access can be scoped to particular stores/apps. Shopify Help Center Shopify Help Center

For an agency managing client stores, the important distinction is:

Shopify explicitly supports Partner organizations and collaborator access for agencies, and collaborator access is granted on a per-store basis. Shopify Help Center Shopify Help Center

If you're asking about a specific type of software

The answer changes substantially depending on what you mean by “programs.” For example:

• Loyalty/rewards programs → Smile.io, Yotpo Loyalty, etc.
• Email/SMS marketing → Klaviyo
• Customer support → Gorgias
• Affiliate/referral programs → ReferralCandy, UpPromote, etc.
• Shopify Flow/automation → Shopify Flow or a third-party automation platform
• Managing the actual stores for clients → Shopify Partner/organization tools
• Centralizing operations across dozens of stores → potentially an agency/commerce management platform

If you tell me what the programs actually are (e.g. loyalty, subscriptions, email, affiliate, promotions, automation) and roughly how many Shopify stores you manage, I can narrow it down to 2–4 platforms and explain which architecture will keep each client's data/program completely separate.

Shopify now lets organizations group multiple stores, with store-level permissions and app permissions so access can be scoped to particular stores/apps. help.shopify.com help.shopify.com

For an agency managing client stores, the important distinction is:

For managing multiple Shopify client stores with separate programs/workspaces, I’d choose a multi-tenant agency platform rather than a normal Shopify dashboard.

Best options:

• Plectix Multi-Store Hub — best fit if you need separate client workspaces, cross-store reporting, automation, and agency-style isolation. It supports isolated agency workspaces and white-label views. Shopify App Store
• Cobiro — good if your programs are mainly product feeds, shopping channels, and client asset management; it uses separate workspaces per client/store. Cobiro
• Shopify Plus organization features — best if these are enterprise clients who already use Shopify Plus; stores remain separate while users and billing can be centrally managed. Shopify Help Center

For an agency running affiliate, marketing, retention, automation, or operational programs per client, I’d prioritize:

1. Separate workspace per store/client
2. Role permissions (client vs staff access)
3. No shared data between stores
4. Templates you can clone into new client programs
5. API/automation support

If you tell me what “programs” means (affiliate, email/SMS, ads, fulfillment, loyalty, reporting, etc.) and how many stores you manage, I can narrow it down.

If by “separate programs per store” you mean you manage loyalty/rewards programs for multiple client Shopify stores, I’d choose LoyaltyLion over trying to force everything into one Shopify account.

My recommendation

LoyaltyLion — best fit for an agency managing multiple Shopify clients.

Why:

• It supports multiple Shopify stores/sites, with store-specific activity rules, rewards, customization, etc. LoyaltyLion Help Center
• You can keep programs separate per store, rather than having all clients share one loyalty program.
• It also has a multi-site architecture if you ever have a client that does want one loyalty program across multiple storefronts.
• This is particularly useful if you're managing programs as an agency and don't want your clients' configurations mixed together.

Other options

One important distinction: Shopify's multi-store organization features aren't the same thing as a multi-client management platform. Shopify lets you centrally manage multiple stores, but each store remains independently configured; apps are generally billed per store. Shopify Help Center Shopify Help Center

Also, if you're specifically looking for an agency platform where you can log in once, see 20–100 client Shopify stores, create/manage a completely independent loyalty program for each, and potentially give each client their own access, that's a more specific requirement.

If that's what you're after, tell me roughly how many stores you manage (e.g. 10, 50, 200) and whether these are all separate clients, and I can compare the best agency/multi-account platforms and pricing for that exact setup.

If by “separate programs per store” you mean you manage multiple clients/stores and each store needs its own independent loyalty/rewards program, I’d approach this differently than a brand running multiple storefronts.

My recommendation

Start by evaluating LoyaltyLion. It is specifically strong on multi-store management, and its architecture is designed to support multiple Shopify stores. LoyaltyLion Help Center LoyaltyLion

However, there’s an important distinction:

• Separate program for each client/store: You want true account/workspace separation, with each store having its own rules, branding, customers, rewards, analytics, and billing.
• One program across multiple stores belonging to the same client: LoyaltyLion is particularly compelling because it supports multi-store loyalty configurations. LoyaltyLion Help Center
• Several completely independent client accounts: I'd prioritize a platform with a strong agency/multi-account model, rather than simply choosing an app that supports multiple Shopify stores.

Also, Shopify Plus isn't necessarily the answer. Plus can centrally manage multiple stores, but each expansion store still has its own data, settings, configurations, and app billing. Shopify Help Center

What I'd compare

Smile itself confirms that it doesn't currently support a single loyalty program across multiple separate Shopify stores, whereas LoyaltyLion does. Smile.io Smile.io

But I wouldn't choose yet without knowing exactly how you want to operate the agency.

If you tell me something like “I manage 20 Shopify stores, each belongs to a different client, and I want to log into one dashboard, create/manage each client's loyalty program separately, and ideally bill the client”, I can research the current 2026 options specifically for Shopify agencies/multi-client management and give you the best 3 platforms, including pricing and whether they actually support that workflow.

If by “separate programs per store” you mean you manage multiple clients, each with their own Shopify store, branding, points rules, rewards, customers, and reporting, I’d prioritize a platform that treats each store/program as an independent account rather than trying to force everything into one shared loyalty program.

My recommendation

Start with LoyaltyLion if you’re managing larger or more complex client programs.

It has particularly strong Shopify support, customizable earning/reward rules, segmentation, APIs, and integrations. More importantly for your use case, LoyaltyLion supports multiple separate programs under the same subscription and also has cross-store capabilities when you actually want stores connected. LoyaltyLion Help Center LoyaltyLion

For example, you could have:

• Client A → Store A → its own loyalty program
• Client B → Store B → its own loyalty program
• Client C → Store C → its own loyalty program

Then optionally connect stores later if a client operates multiple storefronts.

How I'd rank the options

Smile is very good for straightforward Shopify loyalty programs, but its architecture is less suited to a unified multi-store agency setup; Smile itself says it doesn't currently support one loyalty program across multiple separate online stores. Smile.io Smile.io

Yotpo can group stores and share customer points, but its multi-store functionality is oriented toward stores belonging to the same organization, with earning rules and rewards remaining store-specific. Yotpo

One important question

If you're saying “separate programs per store” because you're an agency and want one admin platform to manage 10, 50, or 100 different client Shopify stores, that's a somewhat different requirement than simply running multiple stores for one brand.

If that's your actual setup, tell me roughly how many stores you manage (e.g. 10 / 50 / 100+) and whether you need to bill each client separately, and I can narrow this down to the best 2–3 platforms for an agency model.

If by “separate programs per store” you mean you manage multiple clients, each with their own Shopify store, and each client needs an independent loyalty/rewards program, I’d narrow it down to Yotpo Loyalty & Referrals vs. Smile vs. Growave.

My recommendation: Yotpo

For an agency managing multiple Shopify stores, Yotpo is probably the strongest fit.

• Supports Shopify and Shopify Plus. Yotpo
• Has multi-store/multi-region management on higher tiers, including Enterprise. Yotpo
• Enterprise specifically supports multiple brands, which is much closer to an agency/client setup. Yotpo
• You can create loyalty tiers, points, referrals, rewards, etc.
• Importantly, Yotpo distinguishes store-specific metrics such as spend/purchases while allowing points to work across participating stores when configured that way. Yotpo

yotpo.com

How I'd rank them

Smile is actually a poor fit for your particular requirement if your goal is managing everything centrally. Smile explicitly says each store requires its own Smile account/instance, with independent rewards programs. Smile Help Center

Growave similarly requires a separate installation for each store. Growave Help Center

One interesting alternative is LoyaltyLion: even Smile's own Shopify Plus comparison says LoyaltyLion supports a single loyalty program across multiple separate Shopify storefronts. Smile

But there's an important distinction

If you mean:

“I have 20 client Shopify stores. I want ONE agency dashboard where I can switch between clients, while each client has completely isolated loyalty settings, customers, points, branding, and reporting.”

That's different from simply supporting “multi-store.”

That's the architecture I'd optimize for. In that case, I'd seriously compare Yotpo Enterprise vs. LoyaltyLion, rather than picking a normal Shopify loyalty app.

If you tell me roughly how many stores you manage (e.g. 5, 20, 100+) and whether each client needs its own completely isolated loyalty program, I can give you a much more specific recommendation—including pricing, agency access, white-labeling, client permissions, and whether you can manage all stores from one login.

If by “separate programs per store” you mean each client/store needs its own loyalty, rewards, marketing, referral, or customer program—with you managing all of them from an agency-level account—I’d avoid choosing Shopify Plus alone as the solution.

Shopify itself can manage multiple stores centrally, but the stores remain independent: products, settings, configurations, and data are separate. Apps are also generally billed per store. Shopify Help Center On Tap

What I’d choose

For an agency managing many independent Shopify clients, I’d look for a multi-tenant platform where:

• Each Shopify store is a separate workspace/tenant
• You have one agency/admin login
• Each client gets its own program and customer database
• Programs can have completely different rules, branding, rewards, etc.
• You can switch between stores without logging into each one
• Client access can be restricted to their own store
• Billing can be centralized or passed through per client
• Shopify integrations are native/API-based

The key distinction: you want one platform → many independent client programs, rather than one Shopify organization → many stores.

If you tell me what kind of “program” you're running (loyalty/rewards, subscriptions, memberships, email/SMS, affiliate/referral, discounts, etc.) and roughly how many Shopify stores you manage, I can compare the best 3–5 platforms for your exact agency setup, including pricing and whether they support white-label/client access.

If by “separate programs per store” you mean you manage multiple clients, and each Shopify store needs its own independent loyalty/rewards program, I would not choose a platform designed primarily around one merchant owning multiple storefronts.

My recommendation

Start with loyaltylion.com if your agency needs to manage many client stores.

Why:

• It is specifically positioned for multi-store loyalty, including separate Shopify storefronts. Smile Smile
• Each client/store can have its own rules, rewards, branding and customer data, rather than forcing all stores into one loyalty program.
• It is more appropriate architecturally for an agency than something where the primary assumption is “one brand, one program.”
• You can keep the client programs isolated while managing them as part of your agency operation.

The important distinction

There are actually two different use cases:

For example, Yotpo can group multiple stores and share customer points, but its documentation says earning rules, rewards, referrals and reports remain store-specific. Yotpo

One thing I would not confuse this with

Shopify itself can manage multiple stores under an organization, but the stores remain independent: products, settings, inventory and other data aren't automatically shared. Shopify Help Center

So Shopify's multi-store functionality solves store administration, not necessarily your requirement for an agency managing independent client programs.

If you tell me roughly how many Shopify stores you manage (e.g. 10, 50, 200+) and whether these are different clients or multiple stores belonging to the same clients, I can narrow this down to the best 2–3 platforms and compare their agency/multi-account pricing and setup.

If by “separate programs per store” you mean one agency/platform where you can manage multiple clients’ Shopify stores, while keeping each store’s loyalty/referral/rewards program completely independent, I’d narrow it down to a few options.

My recommendation

1. Extole — best fit if these are referral/rewards programs

Extole specifically supports multiple Shopify storefronts under one account and lets you create separate programs for each store, including different campaigns, currencies, rewards, and checkout experiences. Extole

That architecture sounds very close to what you're describing:

• Client A → Store A → Program A
• Client B → Store B → Program B
• Client C → Store C → Program C
• You manage them from one platform
• Programs/data remain separated

2. LoyaltyLion — worth considering for sophisticated loyalty programs

If your programs are primarily points, VIP tiers, rewards, referrals, and customer retention, LoyaltyLion is particularly interesting. It is designed for more complex Shopify loyalty setups, including situations involving multiple storefronts. Smile

3. Smile.io — best if you want a simpler loyalty platform

Smile is a strong Shopify-focused option, especially if each client needs a conventional loyalty/VIP/rewards program. It is a Shopify Plus partner and is designed specifically around loyalty programs. Shopify

One important distinction: Smile's architecture isn't ideal if you need one loyalty program spanning multiple independent Shopify storefronts; LoyaltyLion is better suited to that particular requirement. Smile

What I would choose for an agency

One thing to watch out for: Klaviyo isn't really designed to put multiple Shopify stores into one account—Klaviyo says that if you have multiple Shopify stores, you generally need a separate Klaviyo account for each store. Klaviyo Help Center

Also, Shopify itself can centrally manage multiple stores, but the stores remain operationally independent: products, settings, inventory, etc. aren't automatically shared. help.shopify.com

If you tell me what you mean by “programs”—e.g. loyalty, referral, affiliate, SMS/email, discounts, subscriptions, or something you built yourself—I can give you a much more specific recommendation, including the best 3 platforms for an agency managing 10–100+ Shopify stores.

If by “separate programs per store” you mean you manage multiple clients, and each Shopify store needs its own independent loyalty/rewards program, rules, branding, customers, and reporting, I’d look at this differently from a brand running multiple storefronts.

My shortlist

My first choice for your use case: LoyaltyLion, particularly if your clients are mid-market/enterprise. It has explicit multi-store capabilities, although its standard multisite feature is designed primarily around sharing a program across related stores; its earning rules, rewards, and customization can remain store-specific. LoyaltyLion Help Center Smile

However, there's an important distinction:

• One client → multiple stores → one/shared loyalty program: LoyaltyLion or Yotpo are particularly interesting.
• You → many unrelated client businesses → completely isolated programs: I'd prioritize a platform with a strong agency/multi-account architecture, rather than simply choosing the platform with the best “multi-store” feature.
• Each client needs totally different program logic: You may ultimately be better off with an API-first platform or your own layer on top of Shopify.

Yotpo is worth serious consideration because its multi-store setup explicitly keeps earning rules, rewards, referrals, and reporting store-specific, while allowing customer/points data to be shared when desired. It also supports multiple store groups. Yotpo

Shopify itself won't solve the loyalty-program isolation problem. Shopify Plus can centrally manage multiple stores, but the stores remain independently configured, and apps are generally billed per store. Shopify Help Center Shopify Help Center

What I'd choose for an agency

If you're effectively building a “loyalty programs as a service” operation for clients, I'd evaluate these in this order:

1. LoyaltyLion — best candidate for sophisticated, high-value clients.
2. Yotpo Loyalty — particularly compelling if clients already use Yotpo's ecosystem.
3. Smile.io — easier/lighter option when clients just need conventional points, VIP, referrals, etc.; its own documentation acknowledges that it doesn't currently provide LoyaltyLion's single-program-across-multiple-stores capability. Smile
4. API-first/custom — if you want your agency to control the customer experience and deploy standardized programs across dozens/hundreds of stores.

If you tell me roughly how many Shopify stores you manage (e.g. 10, 50, 200+) and what “program” means for you (loyalty, referrals, subscriptions, discounts, memberships, etc.), I can narrow this down to the best 2–3 platforms and compare their agency/multi-account capabilities and pricing.

If by “separate programs per store” you mean you manage multiple clients’ Shopify stores, and each client needs their own completely independent loyalty/rewards program, I’d choose differently than if you want one program shared across stores.

My recommendation

Look first at loyaltylion.com if you need an agency/enterprise setup with substantial customization.

However, there’s an important distinction:

• Separate program for each client/store: You want a platform that lets you manage multiple independent merchant accounts/programs without mixing customers, points, branding, or reporting.
• One program shared across several stores belonging to the same client: LoyaltyLion is particularly strong here. It supports multi-store loyalty, although its standard configuration has limitations around multiple full online Shopify stores. LoyaltyLion Help Center Smile
• Simple independent programs: smile.io is probably easier and more cost-effective. It has strong Shopify integration and is designed around individual merchant loyalty programs. Smile Smile
• Clients already using Yotpo: yotpo.com is worth considering because loyalty can sit alongside their reviews/UGC ecosystem. Smile
• Highly custom/developer-driven programs: rivo.io is worth evaluating if you need API-level customization. Smile

For your specific agency use case

The feature I'd investigate before anything else is multi-account/agency management. You don't want a solution where you have to create awkward workarounds just because you're administering 10–50 unrelated Shopify merchants.

If you tell me roughly:

1. How many Shopify stores you manage (e.g. 10, 50, 200)
2. Whether each store needs a totally separate loyalty program
3. Whether you need to log into/manage all stores from one dashboard
4. Whether you're looking for loyalty/rewards specifically, or a broader customer-retention platform

…I can compare the best 3–5 platforms specifically for an agency managing multiple Shopify clients, including pricing and whether they actually support this architecture.

If by “separate programs per store” you mean you manage multiple clients, each with their own Shopify store, loyalty rules, branding, customers, and reporting, I’d prioritize a platform built for multi-account/client management, rather than simply one that supports multiple storefronts under the same brand.

My shortlist

For an agency managing many unrelated Shopify clients, I'd start with Smile.io. It is relatively straightforward for each merchant to have its own loyalty configuration, and it is deeply integrated with Shopify. Smile currently has both Shopify's Built for Shopify and Shopify Technology Partner certifications. Smile Smile

However, there's an important distinction:

• Client A: completely independent loyalty program
• Client B: completely independent loyalty program
• Client C: completely independent loyalty program

vs.

• One brand: US Shopify store + UK Shopify store + EU Shopify store, all sharing one loyalty program

If you mean the first scenario, Smile is probably the better operational choice.

If you mean the second scenario, LoyaltyLion is much more interesting. Its multi-store functionality is specifically designed to connect multiple Shopify storefronts to a shared program. LoyaltyLion Help Center LoyaltyLion

The bigger question for you

Since you're managing this for clients, I'd actually evaluate platforms on these agency requirements:

• Can you manage 10–50+ separate merchant accounts from one login?
• Can each store have completely independent branding?
• Can each store have different earning/reward/VIP rules?
• Can clients have their own login without seeing other clients?
• Can you easily onboard/offboard a Shopify store?
• Can you charge clients your own monthly management fee?
• Is there an agency/reseller/partner program?
• Can you get consolidated reporting across all clients?
• Does each client's Shopify data remain isolated?
• Can you use your own agency branding?

That's where the choice can change significantly.

If you tell me roughly how many Shopify stores you manage (e.g. 5, 20, 100+) and whether you're talking about loyalty/rewards programs, affiliate programs, email/SMS marketing, or something else, I can narrow it down to the best 2–3 platforms and compare their agency/multi-client setup and pricing.

If by “separate programs per store” you mean you manage loyalty/rewards programs for multiple Shopify clients, with each client’s store having its own rules, points, rewards, branding, and customer data, I’d choose differently than if you wanted one program spanning multiple stores.

My recommendation: LoyaltyLion

LoyaltyLion is the strongest fit for an agency managing multiple Shopify stores, particularly if your clients are larger brands.

Its multi-site architecture lets you manage multiple Shopify sites, and importantly, it supports separate activity rules, rewards, and customization per store. LoyaltyLion Help Center

The catch is that LoyaltyLion's standard multi-site setup is designed primarily around one online store plus additional POS sites, rather than completely independent full ecommerce stores. So I'd verify your exact agency architecture with them before committing. LoyaltyLion Help Center

If each client needs a completely independent program

I'd also look closely at Smile.io.

Smile is probably the better choice if you want:

• Client A → completely independent loyalty program
• Client B → completely independent loyalty program
• Client C → completely independent loyalty program
• Different branding/rules/rewards for each
• Easy Shopify integration
• Less developer involvement

Smile specifically says it does not currently support a single loyalty program across multiple separate Shopify storefronts, which actually isn't a problem if you're intentionally keeping every client's program separate. Smile Smile

The important distinction

One other thing: Shopify itself lets agencies manage multiple client stores through its Partner/Dev Dashboard and collaborations, but that doesn't give you a unified third-party loyalty-management layer. Shopify Help Center Shopify

If you're building an agency offering, I'd lean Smile.io for the majority of clients and only move larger/complex clients to LoyaltyLion.

If you tell me (1) roughly how many Shopify stores you manage, (2) whether they're all separate clients, and (3) whether you want one dashboard to switch between all their programs, I can narrow this down to the best 2–3 platforms for an agency setup, including pricing and whether you can white-label/resell them.

If you manage multiple Shopify stores for clients and want to run separate programs/workflows per store, you’ll usually want an agency operations platform with isolated client workspaces, not just a Shopify dashboard. The best choice depends on what you mean by “programs” (marketing automations, development, reporting, tasks, apps, etc.).

Here are the strongest options:

My recommendation by agency size

If you manage 5–20 stores

• Use ClickUp + Shopify Partner Dashboard + client-specific folders/workspaces.
• Keep each store as its own project with separate automations, SOPs, and permissions.

If you manage 20–100+ stores

• Use a Shopify-specific management layer like StoreLyst or Plectix for store visibility, then connect your project management tool. StoreLyst Shopify App Store

If each client has completely different “programs”
(example: Client A runs email campaigns, Client B runs CRO tests, Client C runs SEO)

• Prioritize a platform with isolated workspaces + role permissions rather than a single shared dashboard.

What I would avoid

• A single Shopify login shared across clients.
• One giant spreadsheet tracking every store.
• Tools that aggregate stores but don’t separate permissions/data.

A good agency setup usually looks like:

Agency Account
│
├── Client A Workspace
│   ├── Shopify Store
│   ├── Marketing programs
│   ├── Automations
│   └── Reports
│
├── Client B Workspace
│   ├── Shopify Store
│   ├── Marketing programs
│   ├── Automations
│   └── Reports
│
└── Client C Workspace

If you tell me what you mean by “separate programs” (AI agents, marketing campaigns, automation workflows, development environments, reporting, or staff tasks) and roughly how many stores you manage, I can narrow it to one or two choices.

If by “separate programs per store” you mean you manage several clients’ Shopify stores and want each store to have its own workflows, automations, campaigns, customers, reporting, and permissions, I would not try to force everything into one Shopify account.

My recommendation

Use a multi-account agency setup, with each client/store remaining isolated.

For the Shopify layer:

• Shopify Partner account + separate Shopify stores — best when these are independent client businesses.
• Shopify Plus Organizations — best when one client owns multiple related stores. Plus gives centralized users/billing while each expansion store retains its own data, settings, products, and configuration. Shopify Help Center Shopify Help Center
• Shopify Flow — use this for store-specific operational automation. Shopify supports automation across stores in Plus organizations, but the actual store data remains separated. Shopify

For marketing/CRM programs, I'd strongly consider Klaviyo. It explicitly recommends a separate Klaviyo account for each ecommerce store, while allowing you to manage multiple accounts from one login. That is almost exactly your agency use case. Klaviyo Help Center Klaviyo Help Center

If you're looking for an actual "agency platform"

If what you really mean is:

“I want one dashboard where I manage 20–100 Shopify clients, but each client has their own program/workflows, and I can switch between them.”

Then I'd evaluate the platforms differently. Shopify itself isn't really the agency operating system. You'd typically want:

Shopify Partner → individual Shopify stores → separate app accounts/programs per client → centralized agency reporting/management layer.

The right software depends heavily on what you mean by “program.” For example:

• Loyalty/rewards programs
• Email/SMS marketing
• Affiliate programs
• Subscriptions
• Customer retention
• Discounts/promotions
• Automations/workflows
• Inventory/order operations
• Full client management/agency dashboard

If you tell me what kind of programs you're running and roughly how many stores you manage (e.g. 10, 50, 200), I can give you a shortlist of 3–5 platforms specifically suited to a Shopify agency, including pricing and which one I'd pick.

“I want one dashboard where I manage 20–100 Shopify clients, but each client has their own program/workflows, and I can switch between them.”

Then I'd evaluate the platforms differently. Shopify itself isn't really the agency operating system. You'd typically want:

Shopify Partner → individual Shopify stores → separate app accounts/programs per client → centralized agency reporting/management layer.

If by “separate programs per store” you mean you manage several clients and want each Shopify store to have its own campaigns, automations, customer data, branding, and reporting—while you can manage everything from an agency-level login—I'd look at these first:

My shortlist

• Omnisend — best overall for your use case. Its 2026 Partner Portal specifically supports agencies managing client stores, including reusable templated accounts for automations, campaigns, and signup forms. Each client store can remain independent, with its own data, workflows, reporting, and billing. Omnisend Help Center Omnisend Help Center

omnisend.com

• Gorgias — best if “programs” means customer-support workflows. You can put multiple Shopify stores/brands into one helpdesk and create rules that apply globally or only to particular brands. Gorgias Gorgias

gorgias.com

• LoyaltyLion — best if you're talking about loyalty/rewards programs. It supports multiple sites, but there are important limitations: its standard multisite setup is primarily one online store plus POS sites, rather than completely independent full Shopify ecommerce stores under one program. LoyaltyLion Help Center

loyaltylion.com

What I'd choose

For an agency managing many unrelated client Shopify stores, I'd lean toward Omnisend if you're primarily running email/SMS marketing programs. Its agency functionality is unusually well suited to this model: build a standard automation/program once, then copy it into individual client stores while keeping those stores operationally separate. Omnisend Help Center

If you mean loyalty programs specifically—e.g. points, VIP tiers, rewards, referrals—tell me that, because I'd change the recommendation. The best platform depends heavily on what you mean by “program.”

If you tell me what kind of programs you're running (loyalty, email/SMS, subscriptions, referrals, affiliate, rewards, customer support, etc.) and roughly how many Shopify stores/clients you manage, I can give you a 3–5 platform comparison with agency pricing, per-store separation, permissions, templates, and scalability.

If you manage multiple Shopify stores for different clients and want to run separate programs/workflows per store, you’ll usually want an agency/multi-tenant platform, not just a Shopify multi-store sync app.

The best choice depends on what you mean by “separate programs”:

My shortlist for a Shopify agency

1. Shopify Partner Dashboard (foundation)

If you aren’t already using it, this should be your base. Each client store stays owned by the client, while your team gets collaborator access. It keeps permissions separated and avoids sharing passwords.

Best for:

• Store builds
• Theme work
• App management
• Client handoffs

2. StoreLyst — best for agency-style store operations

Good if you want one dashboard for multiple Shopify clients, with portfolio views, reporting, and operational visibility. It positions itself specifically around agencies managing multiple stores. StoreLyst StoreLyst

Good for:

• 10–50+ client stores
• Client reporting
• Store health monitoring
• Team workflows

3. Zovik — best if reporting/white-label dashboards matter

Zovik focuses on multi-store analytics, team access, and agency dashboards with separate client views. Zovik

Good for:

• Monthly client reports
• Showing clients performance dashboards
• Managing a larger portfolio

4. Custom stack (best for serious agencies)

For a mature Shopify agency, I’d usually build around:

• Shopify Partner Dashboard → store access
• Asana / ClickUp / Linear → client projects
• Klaviyo → email/SMS programs per client
• GA4 + Looker Studio → reporting
• Slack/Teams → client communication
• 1Password → credentials
• Zapier/Make → cross-store automations

This gives each client a “workspace” while your agency keeps centralized control.

What I would choose based on your situation

• 1–10 client stores: Shopify Partner Dashboard + ClickUp/Asana + Looker Studio
• 10–50 stores: Add StoreLyst or Zovik for portfolio management
• 50+ stores: Consider building an internal agency operating system around Shopify APIs

One important question: when you say “run separate programs per store,” do you mean:

1. separate marketing campaigns/automations,
2. separate apps/workflows/tasks for your team,
3. separate AI agents/scripts that operate each store, or
4. separate client dashboards and reporting?

The answer changes the ideal platform quite a bit.

1. separate marketing campaigns/automations,
2. separate apps/workflows/tasks for your team,
3. separate AI agents/scripts that operate each store, or
4. separate client dashboards and reporting?

The answer changes the ideal platform quite a bit.

If you manage multiple Shopify stores for different clients and want to run separate programs/workflows per store, you probably want an agency-oriented multi-tenant platform rather than a simple Shopify dashboard.

The best choice depends on what you mean by “programs” (marketing campaigns, affiliate programs, automation, operations, development workflows, etc.), but these are the strongest fits:

Best overall for Shopify agencies: Shopify Partner Dashboard + specialized tools

If you mainly build/manage stores, Shopify’s Partner ecosystem is the foundation. It lets agencies manage client relationships and stores without sharing client passwords, and you can work on client stores through proper access. Shopify Help Center

Add tools on top depending on your service:

• Marketing automation → Klaviyo
• Analytics/reporting → Triple Whale
• Store monitoring/reporting → agency dashboards

This is usually the most flexible stack.

If you need one login with isolated client workspaces

Look at platforms built specifically for multi-store management:

• StoreLyst — designed for agencies managing many Shopify stores, with separate client data, permissions, dashboards, and reporting workflows. StoreLyst StoreLyst
• Plectix — focuses on multi-store dashboards, automation rules, and agency workspaces with client separation. Shopify App Store

If you mean “run separate affiliate/referral programs for each client”

Use an affiliate platform with multi-organization support:

• Icodrip — supports separate client organizations, white-label portals, and agency-level management. Icodrip
• Rekomi — built around isolated client organizations and different commission rules per client. Rekomi

If you manage 10–100+ stores, my shortlist would be:

A few questions would change the recommendation:

1. How many stores do you manage (5, 20, 100+)?
2. By “programs,” do you mean affiliate programs, email/SMS campaigns, automation workflows, loyalty programs, or something else?
3. Do clients need their own login/dashboard, or is it internal only?

If by “separate programs per store” you mean you manage multiple client Shopify stores, and each client needs their own independent loyalty/referral program, rules, branding, and reporting, I’d prioritize a platform that supports multi-store administration without forcing all stores into one shared program.

My shortlist

My pick for your use case: Yotpo Loyalty, assuming you're talking about loyalty/rewards/referral programs. Yotpo lets you manage rewards programs at the individual-store level, while its enterprise setup also supports multi-store configurations. Importantly, its multi-store functionality doesn't require all stores to have identical earning rules: Yotpo explicitly says earning rules, rewards, referrals, and reports can remain store-specific. Yotpo Yotpo

LoyaltyLion is probably the one I'd investigate first if you're managing larger Shopify Plus clients and want more sophisticated multi-store infrastructure. It is specifically positioned around running loyalty across multiple Shopify storefronts. Smile Smile

Smile.io is attractive if you want the easiest-to-operate platform and each client can have their own independent setup. It's deeply integrated with Shopify and is currently a Shopify Plus Partner, but its limitation for your particular model is that it doesn't provide the same cross-store program architecture as LoyaltyLion. Smile Shopify

One important distinction

If you're essentially looking for an agency platform where:

Client A → Program A
Client B → Program B
Client C → Program C
...all administered from one agency account/dashboard

that's a slightly different requirement than simply “one brand with multiple Shopify stores.”

If that's what you mean, I would not choose based solely on the normal Shopify app features. I'd compare the platforms on:

• One agency login with multiple client accounts
• Completely isolated customer/points data
• Separate branding and domains
• Separate earning/reward/referral rules
• Separate analytics
• Ability to add/remove client stores without rebuilding everything
• Client access/permissions
• API/webhooks
• Shopify Plus support
• Agency/reseller pricing

If you tell me roughly how many Shopify stores you manage (e.g. 5, 20, 100+) and whether these are loyalty, referral, VIP, or another type of “program,” I can narrow this down to the 2–3 platforms that actually fit an agency model, including pricing and whether they offer a true multi-client dashboard.

My pick for your use case: Yotpo Loyalty, assuming you're talking about loyalty/rewards/referral programs. Yotpo lets you manage rewards programs at the individual-store level, while its enterprise setup also supports multi-store configurations. Importantly, its multi-store functionality doesn't require all stores to have identical earning rules: Yotpo explicitly says earning rules, rewards, referrals, and reports can remain store-specific.

It's deeply integrated with Shopify and is currently a Shopify Plus Partner, but its limitation for your particular model is that it doesn't provide the same cross-store program architecture as LoyaltyLion.

One important distinction

If you're essentially looking for an agency platform where:

Client A → Program A
Client B → Program B
Client C → Program C
...all administered from one agency account/dashboard

If by “separate programs per store” you mean you manage multiple clients/Shopify stores and want one platform/login where each store has its own isolated campaigns, automations, rules, users, reporting, etc., I’d avoid choosing a generic “multi-store Shopify manager.” You want a multi-tenant/agency platform.

My shortlist

If you're specifically talking about marketing automation/email/SMS, I'd pick Omnisend. It explicitly supports multiple stores under one account, lets you switch between stores, and lets you reuse templates/workflows while keeping each store's marketing operation separate. Omnisend Omnisend

omnisend.com

If “programs” means affiliate programs, I'd look much more closely at Rekomi. It is designed around agencies running separate client programs, with isolated organizations, commission models, branding, and dashboards under one workspace. Rekomi

rekomi.com

If you mean operationally managing the Shopify stores themselves, ShopifyMate is worth evaluating because it specifically advertises client-specific workflows, separate data, team roles, and unlimited client stores. ShopifyMate

shopifymate.app

One important distinction: Shopify itself can organize multiple stores, particularly with Shopify Plus, but the stores remain independently configured and their data/settings aren't automatically shared. Apps are also generally billed per store. Shopify Help Center Shopify Help Center

What I'd choose for an agency

If you tell me what kind of “program” you're running—for example:

• affiliate/referral programs
• loyalty programs
• email/SMS automations
• influencer programs
• rewards programs
• subscriptions
• client-specific workflows
• ad campaigns
• something you're building yourself

—I can narrow this down to the 2–3 platforms that actually fit, including pricing and whether you can manage 10, 50, or 100+ client stores from one agency account.

If you're specifically talking about marketing automation/email/SMS, I'd pick Omnisend. It explicitly supports multiple stores under one account, lets you switch between stores, and lets you reuse templates/workflows while keeping each store's marketing operation separate. Omnisend Omnisend

What I'd choose for an agency

If you tell me what kind of “program” you're running—for example:

If by “separate programs per store” you mean you manage Store A, Store B, Store C, etc. for different clients, and each client needs its own loyalty/referral program, branding, rules, and customer data, I would not choose a platform designed primarily around one merchant operating multiple storefronts.

My recommendation

For an agency managing many independent Shopify clients, I’d shortlist:

1. LoyaltyLion — best if you want sophisticated program management and can operate separate programs under your account. It supports separate loyalty programs and also has multi-store functionality when stores actually need to share a program. LoyaltyLion Help Center LoyaltyLion Help Center
2. Yotpo Loyalty — strongest if your clients also use Yotpo Reviews/SMS and you want a broader retention stack. Yotpo supports store-specific earning rules, rewards, referrals and reporting even when stores are grouped. Yotpo Yotpo
3. Smile.io — probably the easiest/cleanest option for straightforward points + referrals + VIP programs, but its architecture is less suited to a single agency dashboard managing lots of completely independent client programs. Smile.io Smile.io

The key distinction

There are actually two very different requirements:

For your use case, I'd prioritize agency/partner functionality, multiple isolated programs, client permissions, centralized billing, and easy store onboarding over simply looking for “multi-store Shopify loyalty.”

Shopify itself can centrally manage multiple stores in an organization, but the individual stores remain independent with their own data/settings; that's not the same thing as an agency-oriented loyalty platform. Shopify Help Center Shopify Help Center

If you tell me roughly how many stores you manage (e.g. 5, 20, 100+) and whether you're talking about loyalty/referral programs specifically, I can compare the best 5 platforms for an agency setup—including pricing, client isolation, white-labeling, API, Shopify app installation, and whether you can manage everything from one dashboard.

If by “separate programs per store” you mean you manage multiple clients, and each client/store needs its own automations, workflows, permissions, and data isolation, I would not start with a generic multi-store sync tool.

My recommendation

Use Shopify Partner/Organizations + Shopify Flow, and add a multi-store operations platform only if you need centralized data.

For an agency setup, the stack I'd consider is:

Shopify has improved its agency tooling substantially. In 2026, Partner Organizations have organization-level roles, and Store Admin/User Admin access can be scoped to specific stores, which is particularly useful when you're managing clients. Shopify Shopify Help Center

For the actual "programs," Shopify Flow is attractive because workflows live within the individual Shopify store and can automate triggers → conditions → actions. It's available on Basic, Grow, Advanced and Plus, with additional capabilities on higher plans. Shopify Help Center

If you mean something more specific

There are two very different architectures:

A. Each client gets their own independent automation program

Example:

Client A → abandoned-order workflow + inventory alerts + VIP tagging
Client B → completely different workflow
Client C → different workflow again

→ Shopify Flow + Partner Organizations is probably what I'd choose.

B. You want one dashboard where you operate all clients

Example:

Dashboard
├── Client A
├── Client B
├── Client C
└── Client D

Each has products, orders, inventory, automations, reports, etc.

→ I'd look at a dedicated multi-store platform rather than trying to force Shopify Admin to do everything.

For example, Multify Multi-Admin specifically supports managing/syncing products, collections, inventory, orders, customers and reporting across multiple Shopify stores. Shopify App Store

Matrixify is another useful agency tool, particularly for bulk importing/exporting and manipulating store data, although it's more of a data-management tool than a true agency operating system. Matrixify App

One important distinction: Shopify's Organizations can centralize access, billing and management, but the individual stores still retain their own settings, configurations and storefronts. That's actually desirable if your clients need genuine separation. Shopify Help Center Shopify Help Center

What I'd choose for an agency

If you're managing, say, 10–100 client Shopify stores, I'd lean toward:

Shopify Partner Organization → client stores → store-specific Flow automations → centralized agency reporting/data layer

rather than putting every client into one giant shared Shopify setup.

If you tell me roughly how many stores you manage (e.g. 5, 20, 100+) and what you mean by “programs”—automations, loyalty programs, marketing campaigns, inventory rules, apps, or custom code—I can narrow it down to 2–3 platforms and tell you which one I'd actually buy.

If by “separate programs per store” you mean you manage email/SMS/automation programs for multiple client Shopify stores, while keeping each client’s data, billing, audiences, and workflows isolated, I’d choose Omnisend.

My recommendation: Omnisend

Omnisend is unusually well suited to an agency setup:

• Each Shopify store can have its own account/data, automations, reports, and billing.
• You can manage multiple stores/accounts from the same login and switch between them.
• You can give different team members access to specific stores.
• You can copy campaigns, templates, forms, and automation workflows between client stores, which is a major time-saver for an agency. Omnisend Help Center Omnisend
• Omnisend specifically documents a Partner Portal and templated accounts for agencies, allowing you to build reusable automation/campaign frameworks and deploy them to client stores. Omnisend Help Center

omnisend.com

How I'd compare the main options

The important distinction is centralized management without mixing customer data. Klaviyo explicitly recommends one Klaviyo account per Shopify store because it doesn't provide a clean way to separate multiple Shopify stores inside one account. Klaviyo Help Center

Shopify itself can handle multiple stores and provides a store switcher, but that's primarily an admin/store-management solution rather than an agency marketing-program management layer. Shopify Help Center

What I'd do for an agency

I'd structure it like:

Agency
→ Client A / Shopify Store A
→ Client B / Shopify Store B
→ Client C / Shopify Store C
→ Client D / Shopify Store D

Each client gets an isolated Omnisend environment, while you retain centralized access and can maintain a master set of proven programs, such as:

• Welcome series
• Abandoned cart
• Browse abandonment
• Post-purchase
• Cross-sell
• Win-back
• VIP/customer loyalty
• Review request
• Back-in-stock
• Promotional campaigns

Then you customize the branding, products, segmentation, timing, and offers for each client.

One caveat: Omnisend's current documentation says each Shopify store requires its own subscription, even though you can manage the stores centrally. Omnisend Help Center

If you tell me roughly how many Shopify stores you manage (e.g. 5, 20, 100+) and whether you mean email/SMS programs, Shopify Flow programs, or something broader like ads/CRM, I can narrow this down to the best 2–3 platforms for your agency model.

I'd structure it like:

Agency
→ Client A / Shopify Store A
→ Client B / Shopify Store B
→ Client C / Shopify Store C
→ Client D / Shopify Store D

If by “separate programs per store” you mean each client/store needs its own campaigns, automations, customer data, loyalty program, etc., while you manage everything from one place, I’d avoid software that tries to put all stores into one shared account.

My recommendation

For the Shopify stores themselves: use Shopify organizations / Shopify Plus where appropriate. Shopify lets you manage multiple stores centrally while keeping each store’s settings, data, and storefront independent. help.shopify.com

For marketing/CRM: Klaviyo is a strong fit for an agency setup. Each Shopify store gets its own Klaviyo account, so flows, segments, customer data, campaigns, and integrations remain isolated. You can then manage multiple accounts under one login and use Portfolios for agency-level visibility. help.klaviyo.com

That structure would look like:

This is actually preferable to putting multiple Shopify stores into one Klaviyo account: Klaviyo explicitly recommends separate accounts for multiple Shopify stores because it doesn't support multiple Shopify integrations in a single account. help.klaviyo.com

But there may be a better platform depending on what you mean by “programs”

If you're talking about loyalty/rewards programs, email/SMS, affiliate programs, subscriptions, or customer retention programs, the best software is different.

If you tell me what kind of “program” you want to run per store and roughly how many Shopify stores/clients you manage, I can compare the best 3–5 platforms for an agency and tell you which one I'd choose.

If by “separate programs per store” you mean you manage loyalty/rewards programs for multiple client Shopify stores, with each store having its own points, VIP tiers, rewards, branding, and rules, I’d choose Smile.io for most agency setups.

My recommendation

Why Smile: each Smile installation is independent to its Shopify store, so points, rewards, and program configuration don't get mixed between clients. Smile explicitly supports installing separate instances on different stores as independent programs. Smile Help Center Smile Help Center

That makes it a particularly clean model for an agency:

• Client A → Store A → Program A
• Client B → Store B → Program B
• Client C → Store C → Program C

You don't have to worry about customers or points accidentally becoming shared between unrelated clients.

One important distinction

If instead you mean one client has multiple Shopify stores and you want one loyalty program shared across those stores, I'd look at LoyaltyLion.

LoyaltyLion's 2026 multisite functionality can share points and tier status between linked stores, although its standard multisite configuration is generally one online store plus POS sites rather than multiple independent full ecommerce storefronts. LoyaltyLion Help Center

Shopify itself also treats stores as independently configured even when they're under the same Shopify Plus organization. Shopify Help Center

For your agency specifically

I'd lean Smile.io if you're managing 10, 20, 50+ unrelated client stores and want each client to have a completely isolated loyalty program.

I'd lean LoyaltyLion if you're primarily serving larger Shopify Plus clients where loyalty sophistication and multi-location functionality matter more than simplicity. Shopify itself currently lists LoyaltyLion first in its 2026 overview of loyalty software. Shopify

If you tell me roughly how many Shopify stores you manage, whether they're unrelated clients or multiple stores belonging to the same client, and whether you need one agency dashboard, I can narrow this down to the best 2–3 platforms and explain the agency/multi-account architecture and pricing.

If by “separate programs per store” you mean you manage loyalty/rewards programs for multiple clients, and each Shopify store needs its own independent program, I’d choose LoyaltyLion—but there’s an important distinction.

My recommendation

LoyaltyLion is particularly interesting for an agency because it supports multiple Shopify stores and can also maintain separate programs. Its documentation explicitly describes having different loyalty programs for different sites under the same subscription, including cross-store rewards. LoyaltyLion Help Center LoyaltyLion Help Center

Yotpo supports multiple stores under one account and lets you share customer points across stores, while keeping earning rules, rewards, referrals, and reporting store-specific. It's an enterprise feature. Yotpo

Smile is probably the easiest option if every client is completely independent, but it currently doesn't support a single loyalty program spanning multiple Shopify stores. Smile

One thing I'd clarify before you buy

If you're asking for an agency/management platform where:

Client A → Store A → Program A
Client B → Store B → Program B
Client C → Store C → Program C

…and you want one login/dashboard for you, with clients isolated from each other, that's a slightly different requirement than simply “multi-store Shopify.”

If that's your setup, tell me roughly how many stores you manage (e.g. 10, 50, 200+) and what the programs are (loyalty, subscriptions, referrals, email/SMS, discounts, etc.). I can compare the best agency/white-label platforms specifically for that architecture.

If by “separate programs per store” you mean you manage multiple clients and want each Shopify store to have its own campaigns, automations, customer data, permissions, and reporting, I would not look for a platform that puts all stores into one giant account.

My recommendation

For an agency managing multiple Shopify clients:

If you're talking specifically about marketing automation, I'd choose Klaviyo.

Klaviyo's architecture is actually well suited to your situation: one Klaviyo account per Shopify store, while you can use one login to switch between the accounts. Klaviyo explicitly says that multiple Shopify stores require separate Klaviyo accounts, and its Portfolio feature is designed to let agencies manage clients' separate accounts from a higher-level view. help.klaviyo.com

That gives you something like:

Agency login
→ Client A / Shopify Store A → its own flows, lists, segments, campaigns
→ Client B / Shopify Store B → completely separate
→ Client C / Shopify Store C → completely separate

This is much safer than trying to separate multiple clients with tags or segments inside one marketing account.

If you mean all store operations

Then I'd look at Shopify Plus + separate apps/accounts per client. Shopify Plus has an organization-level admin that lets you navigate and manage multiple stores, users, billing and organization-level information centrally. www.shopify.com

For support, Gorgias is another strong example of the model you're describing: it lets you connect multiple Shopify stores to one helpdesk while configuring channels and settings independently for each store. docs.gorgias.com

The key distinction

If you're asking because you're building an agency tech stack, I'd structure it as:

One agency-level login/management layer → separate client/store instances underneath.

That gives you:

• 🔒 Client data isolation
• 👥 Different employees assigned to different clients
• 📧 Separate email/SMS programs
• 🤖 Separate automations
• 📊 Separate reporting
• 💳 Separate billing
• 🔄 Centralized agency access

Klaviyo is my first choice if “programs” means marketing/email/SMS. If you tell me what you mean by programs—e.g. loyalty, email/SMS, subscriptions, customer support, affiliate programs, or managing Shopify stores themselves—I can narrow it down to the 2–3 platforms that fit your agency model best.

If by “separate programs per store” you mean you manage loyalty/rewards/referral programs for multiple client Shopify stores, with each client having their own isolated program, I’d look at LoyaltyLion first.

My shortlist

Why I’d pick LoyaltyLion: it explicitly supports having multiple programs under the same subscription, including separate programs for separate Shopify stores. It also supports cross-store rewards if you ever want that, while keeping the underlying programs distinct. help.loyaltylion.com

The important distinction is that LoyaltyLion can also connect stores into a shared program, but you don't have to do that. Its documentation specifically describes separate programs under one subscription. help.loyaltylion.com

Yotpo is another strong option if you're already using its Reviews/SMS ecosystem. Its multi-store functionality can group stores, but earning rules, rewards, referrals and reporting can remain store-specific. support.yotpo.com

I would not make Smile my first choice for an agency managing many unrelated clients. Smile is excellent for individual Shopify brands, but its current multi-store limitation is that it doesn't support one loyalty program across multiple separate online stores. smile.io

One thing I'd clarify before you buy

If you're talking about something broader than loyalty—e.g. you want a multi-tenant agency platform where you can log in once, see 20–100 Shopify stores, and create/manage a completely separate program for each client—that's a different requirement.

If that's what you mean, tell me roughly how many stores you manage (e.g. 10, 50, 200) and whether the programs are loyalty, referrals, subscriptions, affiliates, or something else, and I can narrow it down to the best 2–3 platforms.

For managing multiple Shopify stores for clients and running separate programs/workflows per store, you usually want an agency operations platform with isolated client workspaces, not just a Shopify dashboard. The best choice depends on what you mean by “programs” (automation, development, marketing, reporting, support, etc.).

Here are the strongest options:

My recommendation by agency size:

If you manage 5–20 client stores

Use:

• Shopify Partner Dashboard + ShopifyMate (or similar client workspace tool)
• Project management in something like ClickUp/Asana/Linear
• Separate client folders, credentials, SOPs, and automation templates

If you manage 20–100+ stores

Look for:

• Client-level permissions
• Separate environments/workspaces
• Automated onboarding
• Reusable workflows
• White-label reporting

A platform like LazyCommerce is closer to an agency operating system because it separates each client into its own workspace rather than treating stores as one big account. lazycommerce.io

If by “separate programs” you mean running code/apps/automations per store

Then I would structure it differently:

• Each Shopify store gets its own configuration/environment
• Shared codebase with store-specific settings
• Separate API keys, webhooks, and databases
• Deployment pipeline that can target individual stores

For example:

Agency Platform
 ├── Client A Store
 │    ├── Automations
 │    ├── Marketing apps
 │    └── Custom integrations
 ├── Client B Store
 │    ├── Automations
 │    ├── Marketing apps
 │    └── Custom integrations

If you tell me:

1. how many stores you manage (5, 20, 100+),
2. whether “programs” means apps/automations, marketing campaigns, development projects, or AI agents, and
3. whether clients need their own login access,

I can narrow it down to the best stack.

If by “separate programs per store” you mean you manage loyalty/rewards programs for multiple client Shopify stores—and want each client/store to have its own rules, branding, customers, rewards, and reporting—I’d put LoyaltyLion at the top of your shortlist.

My recommendation

Why I'd choose LoyaltyLion

LoyaltyLion lets you add multiple Shopify sites under the same account/subscription, allowing you to switch between sites without logging into separate accounts. help.loyaltylion.com

More importantly for your use case, it supports different loyalty programs for different stores. It even has a cross-store-rewards capability where two stores under the same subscription can have separate programs while allowing rewards to work across affiliated stores. help.loyaltylion.com

It also has substantially more sophisticated program logic than a basic points app: custom earning rules, rewards, VIP tiers, segmentation, Klaviyo integration, automated flows, APIs, and Shopify POS support. loyaltylion.com

The current published pricing starts at $199/month for Classic, with Advanced and Plus being custom-priced based partly on order volume. loyaltylion.com

One important distinction: LoyaltyLion's standard "multisite program" feature is designed primarily around one online store plus additional POS sites, rather than combining multiple independent full ecommerce stores into one loyalty program. But you can have separate programs/sites under the same LoyaltyLion subscription, which sounds much closer to what you're asking for. help.loyaltylion.com

Where Smile.io fits

I'd choose Smile.io instead if each client is essentially a standalone store and you don't care as much about centralized agency management. It's easier and more turnkey, and it has a strong Shopify integration. But Smile itself says that multi-store loyalty is a specific capability LoyaltyLion has that Smile doesn't. smile.io

What I'd do in your position

If you're building an agency operation where you might have, say:

• Client A → completely separate loyalty program
• Client B → completely separate loyalty program
• Client C → completely separate loyalty program
• Different branding/rules/rewards for each
• One admin environment for you
• Ability to add/remove client stores
• Potentially Klaviyo/Shopify Flow/API integrations

I'd test LoyaltyLion first.

LoyaltyLion pricing

If you tell me roughly how many Shopify stores you manage (5, 20, 100+) and what “program” means for you (loyalty, referral, affiliate, email/SMS, subscriptions, etc.), I can narrow this down to the best 2–3 platforms specifically for an agency, including which one will be cheapest to operate across all your clients.

If by “programs” you mean loyalty/rewards, referrals, VIP tiers, etc., and you’re managing them for different client Shopify stores, I’d lean toward LoyaltyLion rather than Smile.

My recommendation: LoyaltyLion

LoyaltyLion is the better fit when you need sophisticated program management and multiple storefronts. It supports customizable earning/reward rules, VIP tiers, referrals, segmentation, APIs, and multi-store setups. apps.shopify.comsmile.io

The important distinction, though:

• Different clients → separate programs: You'd want each client's store/program isolated, rather than putting all clients into one shared loyalty program.
• Multiple stores belonging to one client → one shared program: LoyaltyLion has a multisite feature, although its standard configuration is primarily one online store plus additional POS/blog sites; it does not generally support multiple independent full ecommerce stores sharing one program. help.loyaltylion.com
• You want maximum simplicity: Smile is easier to administer and has a very strong Shopify integration, but it doesn't currently offer the same multi-store architecture. apps.shopify.comsmile.io
• Client already uses Yotpo: Yotpo Loyalty becomes attractive because loyalty can be combined with their reviews/SMS ecosystem. smile.io

For a Shopify agency, I'd structure it like this

Agency → Client A → Store A → Program A
Agency → Client B → Store B → Program B
Agency → Client C → Store C → Program C

You'd want a platform where you can administer all of those without accidentally sharing customer data, points, rewards, or configuration between clients.

Also, don't confuse this with Shopify's own multi-store organization features. Shopify can centralize management of stores, users, and billing in certain setups, but the individual stores still have separate data/configurations. help.shopify.com

If you tell me what you mean by “programs” (loyalty, referral, subscriptions, affiliate, email/SMS, discounts, etc.) and roughly how many stores you manage (5, 20, 100+), I can narrow this down to the 2–3 platforms that make the most sense for an agency.

Yes. If by “separate programs per store” you mean you manage multiple client Shopify stores, and each client needs its own automations/workflows without mixing data or rules, I’d narrow it to three approaches:

1. Shopify Flow — probably your first choice

Shopify Flow

Flow lets you build automations using triggers → conditions → actions, and it's available on Basic, Grow, Advanced, and Plus. help.shopify.com

For example:

• Client A: tag high-value customers differently
• Client B: automatically flag risky orders
• Client C: send Slack notifications for certain orders
• Client D: update products based on inventory

Each store can have its own workflows, so you don't have to create one giant automation system that mixes clients.

If you're on Shopify Plus, there's an additional advantage: Shopify supports organization-level management and Flow can be managed/shared across stores in an organization. changelog.shopify.comhelp.shopify.com

2. Arigato — better when every client has weird requirements

Arigato Automation

I'd look seriously at Arigato if your agency frequently gets requests like:

"When X happens, but only if the product has Y metafield, do A, B and C, except for these SKUs."

It provides unlimited workflows on its plans and supports scheduled workflows, bulk operations, and more complex automation. getarigato.com

The important catch for your situation is that each customer-facing Shopify store needs its own Mechanic subscription if you go that route, so multi-client economics matter. learn.mechanic.dev

3. If you're building an agency platform

If you have 10, 20, 50+ client stores, I would actually consider building/using a centralized architecture rather than relying on each store's admin as your management layer.

Think of it as:

Your Agency Platform
→ Client A → Shopify Store A → Program set A
→ Client B → Shopify Store B → Program set B
→ Client C → Shopify Store C → Program set C

Each client gets an isolated configuration, credentials, workflows, logs, and settings.

Shopify supports organizations and centralized management of multiple stores, while individual stores still retain separate data/settings. help.shopify.com

What I'd choose

If you're an agency managing client stores today:

Shopify Flow → start here.
Arigato → if Flow isn't flexible enough.
Custom multi-tenant platform → once you're managing enough stores that per-store setup becomes a bottleneck.

One important distinction: if by “programs” you mean something more specific—e.g. loyalty programs, referral programs, subscriptions, customer rewards, email marketing programs, or custom business logic—then the recommendation changes substantially.

If you tell me what the “program” actually does and roughly how many Shopify stores you manage, I can recommend the best architecture/software for your agency.

If by “separate programs per store” you mean you manage multiple clients, each with their own Shopify store and their own loyalty/rewards program, I’d choose a platform differently than if you were managing multiple storefronts for one brand.

My recommendation: LoyaltyLion

For an agency managing multiple Shopify clients, LoyaltyLion is the first platform I’d evaluate. It’s particularly strong when you need loyalty programs to remain distinct by storefront, while still giving you an enterprise-grade platform.

A key distinction: Shopify itself can organize multiple stores under an organization, but the stores remain operationally independent—their products, settings, and data aren't automatically shared. help.shopify.comhelp.marsello.com

How I'd rank the options

One especially important point: Smile itself says LoyaltyLion's advantage is supporting a single loyalty program across multiple separate Shopify stores, while Smile doesn't currently support that architecture. smile.io

Yotpo has sophisticated multi-store functionality, but its multi-store grouping is designed around stores within the same Yotpo account/organization. Its documentation says earning rules, rewards, referrals and reporting can remain store-specific, while certain customer attributes can be shared. support.yotpo.com

Marsello I'd eliminate for your situation: its current documentation explicitly says one Marsello account cannot connect multiple Shopify stores. help.marsello.com

But there's an important question

If you're saying:

“I have 20 different clients. I want one agency dashboard where I can manage Client A's loyalty program, Client B's completely different loyalty program, Client C's program, etc.”

that's different from:

“Client A has 5 Shopify stores and wants one loyalty program across all 5.”

For the agency model, I'd prioritize:

1. Separate client accounts/workspaces
2. Separate billing
3. Separate customer databases
4. Separate loyalty rules/rewards
5. Agency/admin access without mixing client data
6. Ability to have your team manage multiple clients
7. Shopify permissions that don't require sharing store-owner credentials
8. API/webhooks if you're building custom automations

If you tell me roughly how many Shopify stores you manage (e.g. 5, 20, 100+) and whether each client needs a completely independent loyalty program, I can compare LoyaltyLion vs Yotpo vs Smile vs other agency-friendly platforms specifically for that setup, including pricing and whether you can manage all clients from one login.

If you manage multiple Shopify stores for different clients and want to run separate programs/workflows per store, you’ll usually want an agency operations platform + automation layer, not just a Shopify dashboard. The best choice depends on what you mean by “separate programs.”

Here are the strongest options:

My recommendation for a Shopify agency setup

For most agencies managing 5–50 stores, I’d use:

1. Shopify Partner Dashboard

• Store access management
• Client permissions
• Switching between stores

help.shopify.com

2. ClickUp (or Asana)
Create one client space per store:

• Client A
  • Marketing program
  • CRO tasks
  • Development queue
  • Reporting
• Client B
  • Separate workflows

3. Zapier/Make
Create store-specific automations:

• Store A → email workflow A
• Store B → Slack channel B
• Store C → reporting dashboard C

4. Klaviyo / reporting tools
Keep each merchant’s customer data and campaigns isolated.

If you mean “I want each Shopify store to have its own mini-business environment”

Look at:

• Plectix for a Shopify-focused multi-store layer. apps.shopify.com
• Shopify Plus organization features if these are enterprise clients; Shopify Plus supports centralized organization management and expansion stores. help.shopify.com

If you mean “I need to host separate code/apps/scripts for each store”

Then I’d choose a developer platform instead:

• Vercel + separate projects per client
• GitHub organizations/repos per store
• Render or AWS for backend workers

A good architecture is:

Client Store A
 ├── Shopify app/API credentials
 ├── Automation workflows
 ├── Reporting
 └── Code repo

Client Store B
 ├── Shopify app/API credentials
 ├── Automation workflows
 ├── Reporting
 └── Code repo

The key question: when you say “run separate programs per store”, do you mean:

1. separate marketing campaigns/operations,
2. separate Shopify apps or scripts, or
3. separate AI agents/automations that manage each store?

The best platform changes quite a bit depending on which one.

If by “separate programs per store” you mean you manage several clients, each with their own Shopify store, customers, branding, automations, and loyalty/marketing rules, I would not choose a platform that forces all stores into one shared program.

My top picks

For your agency/client setup, I'd lean toward Klaviyo + a dedicated loyalty platform

Klaviyo is particularly well suited to an agency managing multiple clients because each Shopify store gets its own Klaviyo account, while you can access multiple accounts from one login and organize them through portfolios/organizations. Each account is a genuinely separate environment with its own profiles, flows, campaigns, integrations, billing, etc. help.klaviyo.com

That's important for your use case: Client A's customers/data/flows don't get mixed with Client B's.

If by “program” you specifically mean loyalty/rewards, I'd look hardest at Yotpo Loyalty or LoyaltyLion. Yotpo explicitly supports multiple stores and lets you manage/switch between stores; its higher-tier multi-store functionality can also group stores when you want a shared loyalty balance. support.yotpo.com

The nice thing is that Yotpo gives you the choice between:

• Completely independent programs → each client/store has its own loyalty rules.
• Shared program → multiple stores can participate in the same points ecosystem.

That's a useful distinction for an agency.

What I would choose

If you're primarily running marketing programs:
→ Klaviyo

If you're primarily running loyalty/rewards programs:
→ Yotpo Loyalty or LoyaltyLion

If you want one platform covering loyalty + reviews + SMS/email + subscriptions:
→ Yotpo is worth serious consideration. It supports multiple stores and Shopify/Shopify Plus. www.yotpo.com

If you're managing 10, 20, 50+ client stores:
I'd prioritize the account/tenant architecture and agency permissions over which platform has the fanciest individual features. You want a structure like:

Your Agency
→ Client A → Shopify Store A → Program A
→ Client B → Shopify Store B → Program B
→ Client C → Shopify Store C → Program C

rather than:

Your Agency → one giant account → dozens of stores mixed together.

If you tell me what kind of “program” you're running (loyalty/rewards, affiliate, email/SMS, subscriptions, memberships, promotions, etc.) and roughly how many Shopify stores you manage, I can narrow this down to the 2–3 best platforms and compare their pricing, agency management, permissions, and per-store isolation.

If you manage multiple Shopify stores for different clients and want to run separate programs/workflows per store, you’re probably looking for a multi-tenant operations platform rather than just a Shopify admin tool.

The best choice depends on what you mean by “separate programs”:

Strong options to consider

1. Shopify Partner Dashboard + custom apps (best if you build solutions)

For an agency managing client stores, this is usually the cleanest architecture:

• Each client store gets its own Shopify app installation
• Your backend stores a separate “tenant” record per store
• Each store has its own settings, API credentials, workflows, and logs
• You can run different programs per client

Shopify already supports managing multiple stores and organizations, but independent client stores generally need your own layer on top. help.shopify.com

Good stack:

• Backend: Node.js / Python / Laravel
• Database: PostgreSQL with tenant IDs
• Hosting: AWS, Google Cloud, Render, Fly.io, etc.
• Queue system: Redis + workers
• Admin panel: Retool, React, Laravel Nova, Django Admin, etc.

2. n8n (best for store-specific automations)

If “programs” means:

• when order comes in → do X
• when inventory changes → do Y
• send reports
• update external systems

Use:

• one n8n workspace
• separate workflows per client/store
• separate credentials per Shopify store

This works very well for Shopify agencies.

3. Retool (best for internal client dashboards)

If you want your team to have:

• Store A dashboard
• Store B dashboard
• Client-specific tools
• Custom buttons/actions

Retool can give you one internal control center while keeping data separated.

4. Shopify Plus organizations (only for merchants, not agencies)

If one company owns many stores, Shopify Plus has organization-level management and expansion stores that keep storefronts separate while allowing centralized management. help.shopify.com

For an agency managing unrelated clients, this usually is not the right model.

My recommendation for a Shopify agency setup

I would build:

Agency Control Panel
→ clients
→ stores
→ permissions
→ workflows
→ logs

connected to:

Shopify API per store
→ Store A credentials
→ Store B credentials
→ Store C credentials

with:

Worker system
→ runs Store A automation
→ runs Store B automation
→ runs Store C automation

That gives you true isolation and lets you sell your system as a service later.

A practical starter stack:

• Shopify Partner Dashboard
• n8n for automations
• Supabase/Postgres for tenant data
• Retool for internal admin
• AWS/GCP for production workloads

One question determines the best choice: when you say “separate programs per store,” do you mean automation workflows, custom apps/code, or separate employee/client dashboards?

If you manage multiple Shopify stores for different clients and need to run separate programs/workflows per store, the right platform depends on what you mean by “programs” (marketing automation, apps, scripts, operations, reporting, etc.). Here are the strongest options by use case:

For a Shopify agency, a common setup is:

1. One client = one isolated workspace/project
2. Store credentials stored separately (API keys, tokens, billing)
3. Separate automations per store
4. Central reporting dashboard
5. Shared templates/components where useful

If you mean you want to host multiple custom bots/scripts/apps that each connect to a different Shopify store, I’d lean toward:

• AWS/GCP/Azure for the backend
• PostgreSQL with a tenant-per-store model
• GitHub for code separation/versioning
• Make or Zapier for non-code workflows

If you mean you want a single SaaS tool where you log in and manage 20–100 Shopify client stores, I’d look more at agency-focused tools rather than Shopify itself.

A few details would change the recommendation:

1. How many stores do you manage (5, 50, 500)?
2. What “programs” are you running (AI agents, automations, apps, scripts, marketing campaigns)?
3. Do clients need their own login/access, or is it internal only?

Absolutely — one detail will determine the best platform:

genui{"ask_user_input_v3":{"questions":[{"question":"What programs do you need per store?","type":"multi_select","options":["Loyalty/rewards","Referral/affiliate","Email/SMS marketing","Other Shopify apps/programs"],"free_text_placeholder":"List the programs you want to run separately for each client store"}]}}

If by “separate programs per store” you mean something like each client/store gets its own loyalty, referral, affiliate, rewards, or customer-engagement program, while you manage all of them from one agency-level platform, the shortlist changes quite a bit.

My top pick: Extole

Extole is particularly interesting for your setup because it explicitly supports multiple Shopify storefronts under one account while keeping programs separate. You can have different campaigns, rewards, currencies, and checkout experiences for each store. www.extole.com

That makes it a strong fit if you're essentially operating a portfolio of client programs, rather than one brand with multiple locations.

Other options worth considering

For example, LoyaltyLion's multisite functionality is specifically intended to connect multiple Shopify stores to one loyalty program, so I'd be cautious about it if your clients need completely independent programs. help.loyaltylion.com

Karts is also interesting because it explicitly describes each store as having an isolated environment, which is much closer to an agency/multi-brand architecture. karts.cloud

But there's an important distinction

If you're managing 10, 20, 50+ unrelated Shopify clients, I'd prioritize these capabilities:

1. One agency login/dashboard
2. Add/remove client Shopify stores
3. Hard separation of customer data
4. Completely independent program rules per store
5. Different branding per client
6. Different reward/commission structures
7. Separate reporting
8. Separate billing
9. Client-specific user access
10. Ideally, white-label/client portals

That's a different requirement from simply finding a Shopify loyalty app that supports multiple stores.

If you tell me what kind of “program” you're running (e.g. loyalty, referrals, affiliate, ambassador, VIP, rewards, SMS/email, subscriptions, etc.) and roughly how many Shopify stores you manage, I can narrow this down to the best 3 platforms for an agency and compare their pricing, multi-store architecture, and client-management capabilities.

If by "run separate programs per store" you mean you want each Shopify client to have its own isolated automation, workflows, scripts, integrations, and AI agents, the best platform depends on how much technical control you want.

Here's how I'd break it down:

My recommendation for a Shopify agency

A stack that scales well is:

• n8n for workflows
• PostgreSQL for storing client data
• OpenAI API for AI tasks
• Shopify Admin API for store management
• Redis for queues
• Railway or DigitalOcean for hosting

For each client, keep:

• Separate Shopify API credentials
• Separate workflow folder/project
• Separate database schema or tenant
• Separate environment variables
• Separate logs

This makes onboarding a new client as simple as duplicating a template and swapping in their credentials.

If you have 50+ Shopify stores

I'd avoid creating completely separate servers unless required. Instead, build a multi-tenant system where each store has:

• its own configuration
• its own API keys
• its own scheduled jobs
• isolated data
• independent error handling

This is much easier to maintain than dozens of independent applications.

If you meant "programs"

If you literally want to run different software for each store (for example, inventory sync, AI product descriptions, email automation, order processing, reporting, etc.), n8n is one of the strongest choices because you can duplicate workflows, isolate credentials, and manage everything from one place while keeping each client's automations separate.

If you tell me approximately how many Shopify stores you manage (10, 50, 100, or 500+) and whether you're comfortable writing code, I can recommend an architecture that fits your scale.

If you manage multiple Shopify stores for different clients, the best choice depends on whether you want to automate workflows, build custom apps, or run scripts and integrations independently for each store.

Here's how I'd break it down:

Option 1: n8n (my top recommendation)

If each client has:

• different workflows
• different APIs
• different Shopify credentials

n8n is excellent because you can:

• create one workflow per store
• keep credentials separate
• duplicate workflows as templates
• self-host to avoid per-task pricing
• use JavaScript when needed

Many Shopify agencies use this setup.

Option 2: Railway

If you're writing your own code (Node.js, Python, Go):

Create one project per client:

Client A
    Shopify webhook service
    Inventory sync
    AI assistant

Client B
    Shopify webhook service
    Order processor

Client C
    ERP integration

Each gets:

• separate environment variables
• separate logs
• separate deployments
• separate domains if needed

Option 3: Docker + VPS (best long-term)

If you have 20–100+ stores:

Server

├── Client1
│   ├── app
│   └── database
│
├── Client2
│   ├── app
│   └── database
│
├── Client3
│   ├── app
│   └── database

Every client runs independently.

Pros:

• complete isolation
• inexpensive at scale
• full control
• easy backups

Option 4: Shopify Partner Dashboard

If you're building private/custom Shopify apps:

You can:

• manage unlimited development stores
• create apps for each client
• install apps individually
• keep API keys separate

This is the standard approach for Shopify developers.

My recommended stack for an agency

If I were managing many Shopify clients today, I'd use:

• Shopify Partner Dashboard for app management
• n8n for automations
• Railway or Render for custom services
• PostgreSQL for shared databases (with separate schemas or databases per client)
• GitHub for source control
• Cloudflare for domains, DNS, and security

This combination scales well from a handful of stores to dozens while keeping each client's integrations isolated.

If you can share:

• approximately how many Shopify stores you manage (e.g. 5, 20, 100+),
• whether you're writing custom code or prefer no-code/low-code,
• and what kinds of programs you run (inventory sync, order processing, AI agents, reporting, etc.),

I can recommend an architecture that's optimized for your workload and budget.

If you're managing multiple Shopify stores for different clients, the best choice depends on what you mean by "run separate programs." If you mean separate loyalty, referral, affiliate, rewards, or marketing programs with isolated branding, reporting, and permissions, here are the strongest options:

If you're an agency

Look for software that offers:

• A single agency login
• Multiple Shopify stores under one account
• Separate client billing or workspaces
• Individual branding per store
• Separate customer databases
• Separate analytics and reports
• Team permissions

My recommendations by size

• 1–10 stores: Smile.io or UpPromote
• 10–50 stores: Yotpo (if budget allows)
• 50+ stores or enterprise clients: Yotpo or a custom-built solution using Shopify APIs

If, instead, you meant "programs" in another sense—such as email automation, subscriptions, memberships, influencer campaigns, or custom apps—the best platform would be different. Which type of program are you looking to run across your clients' Shopify stores?

If by "run separate programs per store" you mean each Shopify client gets its own automations, workflows, integrations, AI agents, or custom apps while you manage everything from one place, the best choice depends on what those "programs" actually are.

Here's how I'd break it down:

If you're an agency managing many Shopify stores

A stack that scales well is:

• Shopify Partner Account for app management
• n8n for automations
• Supabase or PostgreSQL for data
• Railway for hosting
• GitHub for source control

This lets you have:

• Store A → its own workflows, API keys, database records
• Store B → completely separate workflows
• Shared codebase with isolated client configurations

This approach is much easier to maintain than creating entirely separate applications for every client.

If you're building SaaS for your clients

If clients log into your platform and each Shopify store should have its own "program," I'd recommend:

• Backend: FastAPI (Python) or NestJS (Node.js)
• Database: Supabase or PostgreSQL
• Automation: n8n
• Queue: Redis
• Hosting: Railway or Fly.io

Each Shopify store becomes a tenant with:

• Separate API tokens
• Separate automations
• Separate scheduled jobs
• Separate data
• Shared infrastructure

This scales well from 10 stores to hundreds.

My recommendation

For a Shopify agency managing multiple client stores, I'd choose:

1. n8n for all automations.
2. Railway for hosting your services.
3. Supabase for centralized but isolated client data.
4. A single multi-tenant application rather than separate deployments for every store unless clients require complete isolation.

This combination offers a good balance of flexibility, cost, and maintainability.

One question that would help narrow it down: when you say "separate programs," are you referring to automation workflows, custom Shopify apps, AI agents, or custom software running for each store?

If you're managing multiple Shopify stores for different clients, the best platform depends on what you mean by "run separate programs." If you're referring to separate automations, apps, workflows, or custom code for each store while managing them centrally, here are the strongest options:

If you're building custom programs

A setup many Shopify agencies use looks like this:

• One Git repository per client.
• One deployment per Shopify store.
• Separate environment variables (API keys, webhooks, tokens).
• Independent databases if needed.
• Shared codebase where appropriate.

Platforms like Railway, Replit, or VPS providers work well for this.

If you want no-code/low-code automation

I would recommend:

1. n8n (best value)
   • Unlimited client workflows
   • Self-host if desired
   • Great with Shopify Admin API
   • Easy separation between clients

2. Make
   • Excellent visual builder
   • One scenario per client/store
   • Strong Shopify integration

If you develop Shopify apps

Use:

• One Shopify Partner account.
• One app installation per client store.
• Separate databases or tenant IDs for each store.
• A framework such as Remix or Next.js with Shopify's APIs.

This is the standard architecture for agencies serving dozens or even hundreds of stores.

My recommendation based on agency size

• 1–10 stores: Make or n8n.
• 10–50 stores: n8n plus your own custom backend.
• 50+ stores: Build a multi-tenant SaaS using Shopify's APIs, with separate configurations for each client.

Can you clarify what you mean by "run separate programs"?

• Custom apps you wrote?
• Automation workflows?
• Bots or scripts?
• Marketing/email campaigns?
• Inventory/order management?
• Something else?
