ChatGPT answers, unedited

Yes. What you’re describing is essentially an agency multi-tenant platform: one agency account, with a separate workspace for each client/brand.

A few platforms currently fit that model particularly well:

• orshot.com — probably the closest match if you're talking about creative/template production. Each client gets an isolated workspace with its own templates, brand assets, API keys and logs. It also supports role-based permissions, white-label embedding, and workspace transfer to a client. Orshot
• picnie.com — built specifically around agencies producing assets for many brands. It has client workspaces, locked brand kits, templates, role permissions and client-specific production pipelines. Picnie
• canva.com — strong if you want a mainstream design tool. It supports Brand Kits, Brand Templates, brand folders, brand controls and permissions around publishing/approval. The main limitation is that its agency/client account structure isn't as explicitly "one isolated tenant per client" as the newer agency platforms. Canva
• relato.com — more oriented toward content/AI workflows than graphic design. Each client workspace can have its own brand library, workflow, members and permissions, while the agency gets a unified dashboard. Relato
• useaims.com — another interesting model: one account can contain multiple isolated brand workspaces, each with its own Brand Kit, assets, history and team. Billing/settings can be restricted to owners/admins. AIMS - AI-Powered Content Creation

If billing is the key requirement

There's an important distinction between:

A. Agency pays the software bill

Agency → Platform
Client A/B/C are just workspaces.

versus:

B. Agency controls client-level billing

Agency
├── Client A → $500/mo
├── Client B → $1,200/mo
└── Client C → $300/mo

For the second model, Invent is particularly interesting: it explicitly offers dedicated client workspaces, feature delegation, managed billing, spending caps, and a consolidated agency dashboard. Invent

The product architecture you're describing

If you're thinking about this as a platform you might build, I'd model it roughly as:

AGENCY
│
├── Team
│   ├── Admin
│   ├── Account Manager
│   └── Designer
│
├── CLIENT A
│   ├── Brand Kit
│   ├── Templates
│   ├── Assets
│   ├── Users / Permissions
│   ├── Usage
│   └── Billing
│
├── CLIENT B
│   ├── Brand Kit
│   ├── Templates
│   ├── Assets
│   ├── Users / Permissions
│   ├── Usage
│   └── Billing
│
└── CLIENT C
    └── ...

The really valuable part isn't just "multiple workspaces." It's letting the agency create a client workspace from a template, then customize the brand, permissions, templates and billing rules without duplicating the entire account.

If you're asking because you're considering building something like this, I can also break down the existing landscape and identify the gap none of these platforms seem to solve well.

Yes. What you’re describing is essentially an agency multi-tenant platform: one agency account, with a separate workspace for each client/brand, where you can control templates, access, branding, and billing independently.

A few options stand out:

If your main need is design templates

I'd look closely at Marq. It supports multiple brands within one account, brand-specific access, locked templates, brand assets, permissions, and approval workflows. Marq Marq Help Center

marq.com

If you want a separate mini-platform for every client

Orshot is particularly interesting. It gives you isolated client workspaces with their own templates, brand assets, users/roles, API keys, etc., and can even embed the editor into your own white-labeled client portal. Orshot

orshot.com

If billing per client is the important part

Invent is closer to the SaaS/reseller model you're describing. It explicitly supports sub-organizations, feature delegation, managed billing, spending caps, team/role management, and consolidated agency reporting. Invent

useinvent.com

There are also newer platforms explicitly building around this exact architecture. For example, XainFlow describes each client workspace as having its own brand settings, team permissions, assets, and billing, while Relato has a workspace-per-client model with separate brand libraries and scoped permissions. XainFlow Relato

The architecture I'd look for

If you're evaluating this because you want to build or buy something for your agency, the ideal setup is:

Agency
→ Client A workspace
→ Client B workspace
→ Client C workspace

Each workspace should have:

• 🎨 Its own brand kit / fonts / colors / logos
• 📐 Its own template library
• 👥 Its own users and permissions
• 🔒 Isolation from other clients
• 💳 Its own subscription/billing
• 📊 Its own usage/accounting
• 🏷️ Client-specific branding/white-labeling
• 🔄 Ability for your agency team to switch between clients
• 📋 Ability to clone a standard template/workflow when onboarding a new client

If you're specifically talking about a platform where your agency sells template-based creative production to clients—e.g. “Client logs in → chooses their brand → edits approved templates → downloads/publishes → agency bills them monthly”—I can narrow this down to the 3–5 platforms that most closely match that exact business model, including pricing and whether clients can pay separately.

If your main need is design templates

I'd look closely at Marq. It supports multiple brands within one account, brand-specific access, locked templates, brand assets, permissions, and approval workflows. Marq Marq Help Center

marq.com

If you want a separate mini-platform for every client

Orshot is particularly interesting. It gives you isolated client workspaces with their own templates, brand assets, users/roles, API keys, etc., and can even embed the editor into your own white-labeled client portal. orshot.com

orshot.com

If billing per client is the important part

Invent is closer to the SaaS/reseller model you're describing. It explicitly supports sub-organizations, feature delegation, managed billing, spending caps, team/role management, and consolidated agency reporting. useinvent.com

Yes. What you’re describing is essentially an agency/multi-client brand management platform where the agency has one master account, but each client gets an isolated workspace with its own templates, users, permissions, and ideally billing.

A few options stand out:

1. Marq — closest fit for templates + permissions

Marq

Marq is probably the closest match if the core product is branded templates/content creation.

It supports:

• Separate groups/subgroups for different teams
• Brand-specific template libraries
• Template-level permissions
• View-only, user, and admin roles
• Brand assets, fonts, logos, colors
• Template locking so clients can't break the design
• Approval workflows
• Enterprise roles for template, group, billing, etc. www.marq.com

The catch: its pricing is fundamentally based around licenses within an account, rather than being purpose-built as an agency "Client A / Client B / Client C" hierarchy. Enterprise gives you much more control, including group management and custom roles. www.marq.com

2. Canva — good if clients mainly need to create/edit designs

Canva

Canva can be structured with teams, Brand Kits, templates, folders, permissions and roles, and agencies can manage branded environments for clients. There are also Canva agency partners specifically doing this kind of setup. partners.canva.com

But it's less naturally designed around:

Agency → 30 clients → each client has their own billing, permissions, templates, users

You can make it work, but the account/workspace architecture and billing model are important limitations to investigate.

3. A custom/white-label client portal

If what you really mean is something more like:

Agency
→ Client A
→ Client B
→ Client C
→ Client D

with each client having:

• their own brand
• their own template library
• their own users
• client-specific permissions
• client-specific subscription/billing
• agency admins who can see/manage everyone
• optional white-labeling

then I don't think the mainstream design tools are quite the perfect product.

There are platforms built around the multi-client workspace concept. For example, Draftbase explicitly supports one agency login with separate organizations per client, isolated content/templates, client-specific billing and scoped roles. draftbase.co

If you're asking because you're thinking about building this

There's actually a pretty clear product gap here.

I'd model it as:

Then you could have something like:

Agency Dashboard

Acme Creative

→ Nike — 12 users — $299/mo
→ Starbucks — 8 users — $199/mo
→ Local Dental — 3 users — $79/mo
→ Real Estate Co — 17 users — $399/mo

Agency staff can jump between clients without separate logins, while each client sees only their own brand environment.

That architecture is substantially more compelling for agencies than simply giving them a giant Canva/Marq account.

If you tell me what kind of templates you're talking about (social posts, websites, proposals, ads, emails, documents, etc.), I can narrow this down to the 5–10 platforms that actually fit and compare their multi-client + permissions + billing architecture.

Yes. What you’re describing is essentially an agency multi-tenant platform: one agency account, with isolated client/brand workspaces, each having its own templates, permissions, users, and billing.

A few platforms are particularly close:

If you mean a platform for creative templates specifically

Orshot looks unusually close to your description. It explicitly supports a workspace per client, with isolated templates, brand assets, API keys and users, plus role-based permissions. It can also be white-labeled/embedded into your own client portal. orshot.com

Canva Enterprise is stronger if the core product is actual graphic design. It supports multiple brands, Brand Kits, brand templates, approvals and granular admin controls. www.canva.com

If you're thinking about building this

The architecture I'd look for is:

Agency
→ Client/Brand A
→ brand kit + templates + users + permissions + usage/billing

→ Client/Brand B
→ brand kit + templates + users + permissions + usage/billing

→ Client/Brand C
→ brand kit + templates + users + permissions + usage/billing

while the agency has a master dashboard to switch between clients.

There are actually relatively few products that combine all four of these cleanly:

1. Per-client template/brand isolation
2. Per-client roles and permissions
3. Agency-wide admin view
4. Per-client billing/usage controls

For example, Canva nails #1–3 but isn't really designed around an agency reselling separate client environments and billing each client. Invent is much closer to the latter model, with sub-organizations, feature delegation, managed billing and spending caps. www.useinvent.com

If you're asking because you want to build a platform like this, I can also map out the existing competitors and identify the gap in the market / what nobody seems to do well yet.

Yes. What you’re describing is essentially an agency/multi-tenant brand management platform: one agency account, multiple isolated client workspaces, with each client having its own templates, brand assets, users/permissions, and billing.

A few options stand out:

Closest match: Orshot

Orshot for Agencies

Orshot is particularly interesting if you're talking about generating branded visual content for many clients. It explicitly supports one isolated workspace per client, with separate templates, brand assets, API keys, and render logs. It also offers a white-label studio that can live inside your client portal. orshot.com

Best for sophisticated brand-template management: Marq

Marq

Marq is stronger if the core problem is "clients need to create things from approved brand templates without breaking the brand." It supports locked template elements, brand assets, custom template libraries, groups, roles, and granular template permissions. help.marq.com

Its Enterprise plan adds custom roles, group management, template management, approvals, API/webhooks, and SSO/SCIM. www.marq.com

The catch is that Marq's pricing is primarily based on licenses within an organization, rather than being purpose-built around "Client A pays $X, Client B pays $Y" under one agency master account. www.marq.com

If billing + client operations matter as much as templates: Trellis

Trellis

Trellis is more of a client operating system. It has multi-tenant access, granular permissions, client portals, Stripe invoicing/billing, and white-label branding. www.justtrellis.com

So if your desired setup is something like:

Agency
→ Client A → Brand A → Templates A → Users A → $500/mo
→ Client B → Brand B → Templates B → Users B → $1,200/mo
→ Client C → Brand C → Templates C → Users C → $300/mo

…and your agency staff can move between all three clients without logging into separate accounts, Orshot/Trellis are closer to the architecture you're describing than Canva-style team accounts.

If you're actually thinking about building a platform like this, that's an even more interesting distinction: the feature set is basically multi-tenancy + brand/template management + RBAC + client-level billing + agency-level administration. I can also map out what the existing competitors do and where there’s a gap in the market.

Yes. If by “platform” you mean one agency account where each client can have its own brand kit/templates, isolated permissions, and separate billing, there are a few options.

Closest matches

1. Marq — probably the closest for brand/template management

Marq supports:

• Multiple brands in one account
• Client/brand-specific template access
• Brand kits with logos, colors, fonts, etc.
• Locked template elements
• Role/group-based permissions
• Separate access to different brands
• Agency-oriented setup and custom account configuration www.marq.com

It even lets you swap brand kits on a template, which is useful if an agency has a common template structure but different client identities. help.marq.com

Marq

Caveat: Marq is strongest on brand governance/content creation. If you specifically need each client to have its own subscription/invoice/payment method, I'd verify that with their sales team rather than assuming the multi-brand functionality equals multi-client billing.

2. Orshot — interesting if you're generating lots of client content

Orshot is explicitly designed around agencies: you can create an isolated workspace for each client, with its own templates, brand assets, API keys and render history. It also offers white-label Studio and agency/partner pricing. orshot.com

Orshot for Agencies

This is particularly interesting if your agency wants to let clients generate their own social graphics, ads, PDFs, etc. from controlled templates.

3. Influentials — closer to an agency operating system

It explicitly offers:

• Multi-brand workspace switching
• Client-level approvals
• Granular agency roles
• White-label reporting
• Consolidated or per-client billing www.influentials.com

Influentials for Agencies

However, its focus appears to be influencer/creator campaign management rather than a general-purpose template/design platform.

If you're actually describing a product you want to build...

The feature combination you described is quite specific:

Agency → Clients → Brand Kits → Templates → Users/Permissions → Billing

I'd model it something like:

AGENCY
│
├── Client A
│   ├── Brand kit
│   ├── Templates
│   ├── Client users
│   ├── Agency users with access
│   └── Billing/subscription
│
├── Client B
│   ├── Brand kit
│   ├── Templates
│   ├── Client users
│   ├── Agency users with access
│   └── Billing/subscription
│
└── Client C
    ├── Brand kit
    ├── Templates
    ├── Client users
    ├── Agency users with access
    └── Billing/subscription

That's actually a fairly underserved SaaS pattern. A lot of tools support multi-brand or team permissions, but fewer treat agency → client → isolated workspace + client-specific billing as a first-class object.

If you tell me what kind of templates you're talking about (e.g. Canva/social posts, email templates, websites, proposals, ads, PDFs, presentations, or something else), I can give you a much tighter list of platforms that support this exact agency model.

Yes. If you mean one agency account where you can manage multiple client brands, each with its own templates/assets, user permissions, and billing, there are several platforms that get close.

Best fits

Orshot is particularly interesting if you're talking about a design/content-production agency. It gives you a separate workspace for each client, with isolated templates, brand assets, API keys and render history. Your agency can switch between clients from one login, while each client can have its own users and roles. It can also be white-labeled/embedded into your own client portal. orshot.com

Orshot for Agencies

ManyRequests is probably the stronger choice if you mean a broader agency operating system: client portals, requests, subscriptions, invoicing, CRM, files, permissions, etc. It specifically supports client-side teams and granular permissions. manyrequests.com

ManyRequests

Tarkle is another good fit if you're selling standardized/productized services. It has white-label client portals, branded checkout, client-managed team access, orders, payments and deliverables. orshot.commanyrequests.comtarkle.com

Tarkle

If you're imagining something more specific...

For example:

Agency
→ Client A
→ Brand A
→ Brand templates A
→ 5 client users
→ Client A pays $2,000/mo

→ Client B
→ Brand B
→ Brand templates B
→ 3 client users
→ Client B pays $750/mo

Agency admins can access everything, but clients only see their own brand.

Yes — that architecture exists, and Orshot is probably the closest match if templates/brand assets are the core product. If billing + projects + client management are equally important, I'd look harder at ManyRequests/Tarkle.

If you're asking because you're considering building this platform, that's also an interesting SaaS model. The combination of multi-tenant client workspaces + brand/template management + agency permissions + per-client billing is still not particularly well served by the mainstream tools.

Yes. What you’re describing is essentially a multi-client / multi-workspace agency platform where each client gets an isolated environment, while your agency has a master view.

A few platforms that fit:

The closest match to your description

Orshot looks particularly close if you're talking about creative/design templates.

It gives an agency:

• One workspace per client
• Separate templates and brand assets for each client
• Role-based permissions within each workspace
• Separate API keys and usage tracking
• Ability to white-label the editor
• Ability to transfer an entire client workspace to the client later orshot.com

Audienceful is another strong match if this is specifically for email marketing. Each client gets separate templates, branding, data, team permissions, and billing, while your agency manages everything from one account. www.audienceful.com

And Canva's agency offering handles the brand/template/permission side very well: Brand Kits, Brand Templates, Brand Folders, and controls over who can edit, publish, or approve. www.canva.com

If you're thinking about building this as a product

The architecture you're describing would usually be:

Agency
→ Client A workspace
→ Brand Kit A
→ Templates A
→ Users/permissions A
→ Billing A

→ Client B workspace
→ Brand Kit B
→ Templates B
→ Users/permissions B
→ Billing B

while the agency gets a master dashboard to switch between clients.

There are actually platforms doing almost exactly this. For example, XainFlow describes isolated workspaces with per-workspace brand colors, fonts, style guides, team permissions, asset libraries, and separate billing/usage tracking. www.xainflow.com

If you tell me what kind of templates you're talking about (social graphics, ads, websites, presentations, emails, proposals, AI-generated content, etc.), I can narrow this down to the 3–5 platforms that most closely match, including pricing and whether the client can log in themselves.

Yes. If you mean an agency operating one platform across many clients, with each client having its own brand kit/templates, user permissions, and ideally separate billing, there are a few good fits.

Best matches

1. Medal Social — probably closest to your exact agency model

Medal Social for Agencies

It explicitly supports:

• One workspace per client
• Separate brand voice/data per workspace
• Different users/seats per client
• Per-client billing
• Agency-wide dashboard to switch between clients
• White-label client-facing experience

This is particularly compelling if the "templates" you're talking about are social/content templates and AI-generated content rather than graphic-design templates.

2. Frontify — strongest for brand/template governance

Frontify is much more mature if you're talking about a creative/marketing agency managing brand guidelines, assets, and reusable templates.

It lets you create separate brand portals with their own permissions, while managing multiple brands centrally. You can also lock portions of templates so clients can edit approved fields without breaking the brand. www.frontify.com

The catch: it's more of an enterprise brand-management/DAM platform than an agency billing/workspace platform. You'd likely need to work out the client billing model separately.

3. Marq — strong for client-specific templates

Marq is worth looking at if the core requirement is:

"I build templates for each client, clients can use them, but they can't mess up the underlying design."

It supports brand templates, locked design elements, user/group permissions, client-specific template collections, and approval workflows. help.marq.com

The distinction I'd make

If your desired architecture is:

Agency
→ Client A workspace
→ Client B workspace
→ Client C workspace
→ each with its own templates + users + permissions + billing

then Medal Social looks unusually close to that model.

If it's more:

Agency
→ 30 different brands
→ each has brand guidelines + logos + fonts + templates + asset library
→ clients/partners get restricted access

then Frontify is probably the better fit.

If you're thinking about building a SaaS product with this architecture yourself, that's also a very recognizable product category: multi-tenant agency workspace / client portal + brand template management + usage-based or seat-based billing. There are still relatively few platforms that do all of those pieces elegantly in one place.

Yes. If you mean a platform where one agency account can manage multiple clients/brands, with each client having its own templates, brand assets, user permissions, and billing, there are a few options.

Closest fits

1. Marq — probably the closest for brand/template management

Marq is specifically built around brand templates and governance. It supports:

• Multiple brand kits
• Brand-specific templates
• Locked design elements
• Permissions by user/group
• Client-specific template collections
• Multiple teams/subgroups
• Admin vs. template-admin vs. user roles
• Separate control over billing/account administration help.marq.com

It even has functionality for people working across multiple clients, locations, or sub-brands, including swapping brand kits on the same template. help.marq.com

The catch: Marq's pricing is primarily per license within an account, rather than being purpose-built as an agency "one account → 50 independent client workspaces → each client gets its own invoice" system. Enterprise is where the more sophisticated group/role/template management lives. www.marq.com

2. Plai — closer to the agency/client model

Plai explicitly has client/brand workspaces, where an agency can switch between clients, control which platforms/features each client sees, and assign role-based access. It also supports Stripe billing and client subscriptions. www.plai.io

This is a better fit if you're thinking:

Agency → Client A → Brand + users + assets + billing
Agency → Client B → Brand + users + assets + billing
Agency → Client C → Brand + users + assets + billing

But it's more of a marketing/ads platform than a dedicated brand-template production platform.

3. Influentials — interesting if reporting/campaigns are the main use case

It specifically advertises a multi-brand workspace switcher, granular agency roles, client-level approvals, and consolidated or per-client billing. www.influentials.com

If you're describing a product you want to build

There is actually an interesting gap here.

What you're describing sounds like an "Agency OS for branded content":

AGENCY
│
├── Client A
│   ├── Brand Kit
│   ├── Templates
│   ├── Assets
│   ├── Users / Permissions
│   ├── Approvals
│   └── Billing
│
├── Client B
│   ├── Brand Kit
│   ├── Templates
│   ├── Assets
│   ├── Users / Permissions
│   ├── Approvals
│   └── Billing
│
└── Client C
    ├── Brand Kit
    ├── Templates
    ├── Assets
    ├── Users / Permissions
    ├── Approvals
    └── Billing

Marq gets closest on the template/brand-governance side; Plai gets closer on the agency → client workspace → billing side. I don't see an obvious dominant platform that combines those two models exceptionally well.

If you tell me what the templates are for (Canva-style social posts, proposals, PDFs, ads, websites, email, print collateral, etc.), I can narrow this down to the 3–5 platforms that actually fit your workflow, including pricing and whether each supports true client isolation.

Yes. What you’re describing is essentially an agency multi-tenant platform: one agency account, with isolated client workspaces where each client can have its own templates, branding, users/permissions, and billing.

A few examples worth looking at:

For your exact description, Orshot is particularly interesting if the "templates" are visual/design templates. It gives an agency separate client workspaces with isolated templates, brand assets, API keys and permissions, plus a white-label editor. orshot.com

If the bigger requirement is "I want to sell a service to clients and control exactly what each client gets/pay for," I'd look closely at Medal Social. It explicitly supports one workspace per client, per-workspace seats/roles, white-labeling, and different billing arrangements per client. www.medalsocial.comseven16groupsupport.com

And Seven16 is closer to the model where the agency itself becomes the reseller: each client gets a branded, isolated workspace, while the agency can choose who pays and bill clients through its own Stripe account. seven16groupsupport.com

If you're thinking about building this

The underlying architecture you'd want is roughly:

Agency
→ Client A workspace
→ Client B workspace
→ Client C workspace

Each workspace has:

• its own brand kit
• its own template library
• its own users + roles
• its own assets/data
• its own usage limits
• its own billing/subscription
• optional custom domain/white-labeling

Meanwhile the agency gets a global admin view and can jump between clients without separate logins.

That's a pretty established SaaS pattern now, often called multi-tenant / parent-child workspaces / agency workspaces.

If you tell me what kind of templates you're talking about (e.g. Canva/social posts, websites, proposals, reports, AI content, ads, email, etc.), I can narrow this down to the 3–5 platforms that most closely match your exact use case.

Yes. What you’re describing is basically an agency operating system with isolated client workspaces:

• One agency account
• Separate workspace/brand per client
• Client-specific templates + brand kits
• Role-based permissions for your team and the client
• Ability to restrict users to specific clients
• Per-client billing or the ability to pass billing through
• Ideally white-labeling so the client sees your agency rather than the underlying software

A few platforms are getting close:

1. Marq — strongest fit for brand/template management

Marq is particularly strong if the core problem is creating and managing branded collateral for many clients.

It supports multiple brands, brand-specific access, lockable templates, user/group permissions, and custom roles. help.marq.com

The interesting part is that its multi-brand system can let a single template adapt its logos, colors, fonts, and other assets depending on the selected brand. help.marq.com

Caveat: Marq is more of a brand/content production platform than a complete agency client-management + billing platform. You'd want to verify exactly how its account/brand structure maps to separate client billing.

2. Medal Social — very close to the agency OS you're describing

Medal Social explicitly markets one workspace per client, separate brand voice/data, per-client seats/billing, and white-labeling. www.medalsocial.com

This is particularly interesting if you're talking about social/content production rather than graphic design.

3. Influentials — another agency-oriented option

Influentials has a multi-brand workspace switcher, granular team roles, client-level approvals, white-label reporting, and consolidated or per-client billing. www.influentials.com

If you're thinking about building this as a product

There is actually a pretty clear product category here:

“Shopify Organizations + Canva brand kits + agency billing, but purpose-built for agencies.”

The key abstraction would be:

Agency → Clients → Brands → Templates → Users/Roles → Usage/Billing

For example:

Your agency employees could have access across clients, while a client user only sees their own workspace.

If that's the product you're considering, I'd say there's still room here. The existing products tend to specialize in one piece—brand management, social media, reporting, CRM, or white-labeling—rather than making client isolation + templates + permissions + billing the central primitive.

If you tell me what kind of templates/content the agency is managing (social posts, websites, ads, proposals, documents, email, etc.), I can narrow this down to the 5–10 closest products and show you where the gaps are.

Yes. What you’re describing is essentially a multi-client agency platform with:

• Separate workspace/account per client
• Client-specific brand templates/assets
• Role-based permissions for agency staff vs. clients
• Separate client billing or usage tracking
• Ideally, one agency login/dashboard across all clients
• Optionally white-labeling so clients see your agency’s branding

A few platforms currently fit that model particularly well:

1. Orshot — strongest fit for branded templates/content production

Orshot is specifically built around agency workflows. Each client can have an isolated workspace with its own templates, brand assets, API keys and render history, while your agency manages everything from one account. It also supports role-based permissions and embedding/white-labeling the studio. orshot.com

Orshot for Agencies

2. Medal Social — strongest fit if this is social/content management

Medal Social offers one workspace per client, separate brand voice, client-level users/permissions, and per-client billing. It also supports white-labeling on its higher tier. www.medalsocial.com

Medal Social for Agencies

3. Relato — good for content workflows

Relato has a workspace-per-client architecture with separate brand libraries, workflows, team members and permissions. You can create a reusable workspace template and then customize it for each new client. www.relato.com

Relato for Agencies

4. MB Suite — good if you want broader client portals

MB Suite uses parent/child workspaces: your agency sits at the top, with each client having an autonomous account, separate data, dashboards, integrations, roles and a white-labeled portal. mb-suite.com

MB Suite for Agencies

The key distinction: if by "brand templates" you mean something like Canva-style templates where each client has their own logo/colors/fonts and your team can produce assets from those templates, Orshot is probably closest to what you're describing. If you mean a broader agency operating system—CRM, projects, reporting, client portals, etc.—I'd look at the workspace-based platforms instead.

If you tell me what you're actually producing (social posts, ads, PDFs, websites, presentations, email campaigns, etc.), I can narrow this down to 3–5 platforms that fit and compare templates + permissions + client billing + white-labeling.

Yes. If by “agency” you mean one agency account that manages multiple clients/brands, with each client having its own templates, users/permissions, and ideally its own billing, there are a few platforms worth looking at.

Closest fit: Marq

Marq is probably the closest match to what you're describing.

It supports:

• Separate brand templates and brand assets
• Template-level permissions — control who can view/use/edit templates
• Groups/subgroups for organizing users by client/team
• Different roles such as account admin, template admin, user, viewer, and billing admin
• Locked templates so clients can customize content without breaking the design
• Approval workflows
• Enterprise/API/SSO capabilities www.marq.com

Marq

The catch: Marq's pricing is fundamentally organized around accounts and licenses, rather than being purpose-built as an agency “Client A / Client B / Client C” multi-tenant system. Its billing admin controls the subscription for the account. help.marq.com

If your requirement is specifically “agency → many independent clients”

That's a slightly different category. You'd ideally want something like:

Agency
→ Client A workspace
→ Client B workspace
→ Client C workspace

And each workspace has:

That true multi-tenant structure is less common among design/template platforms. Many tools can technically accomplish it with separate teams/accounts, but aren't designed around agencies managing dozens of clients.
