Yes. What you’re describing is agency-oriented social media workflow software, not just a scheduler. The critical requirements are:

• Separate workspace/client environments
• Required approval before publishing
• Sequential approvals such as Writer → Account Manager → Legal → Client
• Approval tied to the exact version reviewed
• Full version history and audit trail
• Client access without giving them broad account permissions
• Ability to manage many brands/social accounts centrally

My top pick: Planable

Planable is probably the closest fit. It supports dedicated client workspaces, required approvals, client collaboration, and version history. Its Enterprise tier specifically supports multi-level approval, so you can build something like:

Draft → Internal review → Legal → Client approval → Schedule/publish

Importantly, Planable records versions and lets you compare/restore earlier versions; its multi-level workflow is designed for cases where different stakeholders must approve in a specific order. planable.io

Also worth evaluating

Hootsuite — better if you want a more established enterprise social-management platform around the approval workflow. It supports up to three approval layers, ordered approvers, permissions, and approval history showing who edited/approved content. www.hootsuite.com

Hootsuite

Agorapulse — strong general-purpose option for agencies, with team approval workflows; its Custom enterprise tier adds multi-step approvals, custom roles and SSO. www.agorapulse.com

Maeve Social — particularly interesting if your auditability/version-to-approval relationship is the main concern. It explicitly records who approved what, when, and against which version, and supports internal → client review workflows. maevesocial.com

Maeve Social

What I'd choose

If you're managing many clients and need defensible legal sign-off, I'd shortlist:

One feature I would insist on during demos: if Legal approves Version 7, then someone changes the caption to Version 8, the system should automatically invalidate the approval and require Legal to approve again. Otherwise, you have an approval process but not reliable legal sign-off. That version-locking behavior is specifically called out as an important distinction in modern approval systems. www.kontentino.com

If you tell me roughly how many clients/users you have and whether “legal approval” is internal or the client's legal department, I can narrow this to the best 2–3 platforms and compare their actual pricing/features for your setup.

Yes. For your requirements—many clients + legal approval + auditability + version history—I’d shortlist these:

My pick: Planable

For an agency with lots of separate client accounts, Planable looks particularly aligned. You can give each client its own workspace and approval flow, while keeping your agency's internal discussions separate from client-facing feedback. planable.io

Most importantly, it supports multi-level approval, so you could model something like:

Copywriter → Account Manager → Legal → Client → Schedule

Planable's version history records checkpoints as posts are edited, allowing you to see previous versions and restore them. Its Enterprise tier retains that history indefinitely. planable.ioplanable.io

That's important for legal approval because you ideally want the approval attached to the specific version that was reviewed, rather than simply having a generic "approved" status.

One thing I'd verify in demos

Ask each vendor this exact question:

"If Legal approves version 7 of a post, and someone changes one word afterward, does the approval automatically become invalid and require re-approval?"

That's the key control for your use case. An audit trail showing who edited/approved something is useful, but version-bound approval is much stronger.

If you tell me roughly how many clients/users you have and whether legal approval is mandatory for every post or only certain clients/content, I can narrow this to the best 2–3 platforms and compare their workflows and pricing.

Yes. What you’re describing is agency-grade content approval, not just a social scheduler. The key requirements are:

• Multi-client workspaces with permissions separated by client
• Sequential approvals, e.g. Creator → Account Manager → Legal → Client
• Required approval before publishing
• Version history, with approval tied to the exact version
• Audit trail showing who changed/approved/rejected what and when
• Client approval without necessarily giving clients full platform access
• Calendar/scheduling across multiple social networks

My shortlist

What I'd choose

For many clients + legal approval + defensible version history, I'd demo Gain and Planable first.

If your requirement is more like:

"We have 50+ clients, each has different approval chains, and legal approval has to be provable after the fact."

then Gain is particularly worth investigating because the product is explicitly built around approval records and multiple stakeholder types, including clients and legal. gainapp.com

If your priority is:

"Our clients need a really easy place to review posts, comment, make changes, and approve them."

I'd lean toward Planable. Its version history and multi-level approval model are especially relevant. planable.io

One important requirement I'd make non-negotiable in your evaluation: an approval must become invalid if the approved post is subsequently edited. Otherwise you can have a perfectly documented "Legal approved it" record while the published post is actually different. That's exactly the version-control problem these systems need to solve. www.kontentino.com

If you tell me roughly how many clients/users you have and whether you're an agency or an in-house team, I can narrow this to the 2–3 platforms I'd actually shortlist, including pricing and which one handles the legal/version workflow best.

Yes. For an agency managing many clients where posts need formal legal approval plus a defensible version/audit history, I’d shortlist these:

My first choice: Planable

Planable is particularly well matched to your requirement.

It supports separate workspaces and approval processes for each client, so you could have, for example:

Client → Draft → Internal review → Legal → Client approval → Scheduled → Published

Its Enterprise multi-level approval workflow can enforce sequential approval—for example, creative → legal → executive → client—and prevent scheduling until the required approvals are complete. planable.io

More importantly for your version-control requirement, Planable creates version checkpoints when posts are saved, allowing you to see previous versions, compare them, and restore an earlier version. Enterprise retains that history indefinitely. planable.io

Sprout Social is the other one I'd seriously evaluate

Sprout Social has robust multi-step publishing workflows, including multiple approvers and "all approvers" versus "any approver" behavior. Its Approval Activity records edits, comments, workflow steps, and approval/rejection actions. support.sproutsocial.comsproutsocial.com

It's especially attractive if you also need sophisticated social listening, analytics, reporting, and enterprise permissions across clients. sproutsocial.com

Hootsuite

Hootsuite is another strong enterprise option. It supports custom approval workflows with up to three layers, and its approval history shows who edited, sent, and approved posts. www.hootsuite.com

Bottom line: If the core problem is "our agency needs to prove exactly which version was reviewed and approved by legal before it went live," I'd start with Planable Enterprise. If you need a broader enterprise social-management suite beyond content approvals, I'd compare it closely with Sprout Social.

If you tell me roughly how many clients/users you have and whether legal approval needs to be sequential (e.g. account manager → legal → client), I can narrow this to the best 1–2 options and compare their actual plans/features.

Yes. For your requirements, I’d shortlist Planable, Sprout Social, and Hootsuite—but Planable looks like the closest fit if the core problem is client-by-client content approval and a defensible version trail.

My pick: Planable

Planable is built around agencies and multi-client workflows. It gives you:

• Separate workspaces per client/brand
• Required approvals before a post can be scheduled/published
• Multi-level approvals—e.g. writer → legal → client → final approver
• Version history showing who changed what and allowing restoration of previous versions
• Internal comments/notes that can remain hidden from clients
• Client-facing approval without having to dump everything into email/Docs
• A record of the approval workflow attached to the actual content planable.io

Importantly, Planable specifically describes its Enterprise multi-level workflow as suitable for regulated environments where brand → legal → executive → client approval needs to happen sequentially. Its Enterprise version history is retained indefinitely. planable.ioplanable.io

How I'd compare them

Sprout Social has particularly strong approval controls: multi-step/multi-user workflows, external approvers, permissions, and an Approval Activity trail showing edits, comments, and who made changes. support.sproutsocial.com

Hootsuite supports up to three approval layers and maintains approval history showing who sent, edited, and approved posts. It explicitly positions the workflow for legal/compliance reviewers. www.hootsuite.com

The workflow I'd want

For your use case, I'd configure it roughly as:

Content creator → Account manager → Legal → Client → Scheduled

with the platform preventing publication until the required approvals are complete.

The key distinction is that you're not merely looking for a social scheduler with an "approve" button. You want workflow governance + auditability + version control. On that criterion, I'd start by evaluating Planable Enterprise, then compare it against Sprout Social Advanced/Enterprise.

If you tell me roughly how many clients, posts/month, and whether legal approval is internal or client-side, I can narrow this down to the best 2–3 platforms and what each would cost.

For your requirements—many clients, legal sign-off, mandatory approval gates, and a defensible version history—I’d shortlist these:

I'd lean toward Planable

Planable is unusually well matched to an agency → client → legal → publish workflow. You can make approval mandatory so a post can't be scheduled/published without approval, and Enterprise supports multiple sequential approval levels—for example:

Content team → Legal → Client → Final publisher

It also keeps version checkpoints so you can see what a post looked like at different points, compare versions, and restore an earlier version. Enterprise retains version history indefinitely. help.planable.io

For multiple clients, Planable uses separate workspaces, which makes it straightforward to isolate each client's content, users, approvals, and calendars. help.planable.io

When I'd choose Sprout instead

If you need more than approval management—deep publishing, analytics, social listening, inbox management, and enterprise social governance—Sprout Social is probably the stronger overall platform. Its approval workflows support multiple steps and multiple approvers, and its Approval Activity records edits, comments, and the current workflow step while a post is awaiting approval. support.sproutsocial.com

One important distinction

If "legal approval" means you need an audit-grade record for regulated content, I'd specifically test how each platform handles:

• immutable approval records
• who approved and when
• what exact version was approved
• changes after legal approval
• locking an approved post
• exporting the audit trail
• retention periods
• external/client approvers

Planable can lock content after approval, preventing changes to the approved text/media/scheduling details, which is particularly useful for your use case. help.planable.io

Bottom line: Start with Planable if your core problem is content review/approval across lots of clients. Start with Sprout Social if you want a broader enterprise social-media-management suite and approvals are one component of it. Hootsuite is a strong third option, particularly if governance and documented external approvals are priorities. www.hootsuite.com

Yes. For many clients + mandatory legal approval + auditable version history, I’d shortlist these:

My pick: Hootsuite

For your specific requirement, Hootsuite is probably the first platform I'd evaluate. Its workflow can require sequential approval—for example:

Content creator → Account manager → Legal → Client → Publish

Hootsuite supports up to three approval layers, role-based permissions, and locks approved posts so changes send the content back through approval. Its approval history records who edited/approved content, and its newer external-approval feature can document approvals that occurred outside Hootsuite. www.hootsuite.comwww.hootsuite.com

That last point is particularly useful if your clients' attorneys approve content via email or another system: you can record that external approval against the post rather than losing the audit trail. www.hootsuite.comwww.hootsuite.com

Hootsuite approval workflow

Sprout Social is a very close alternative

Sprout is particularly attractive if you're an agency managing lots of separate client accounts. It supports client-specific groups/permissions, shared calendars, multi-step approval workflows, and external approvers. sproutsocial.com

It also maintains customer-facing audit-trail logs recording user activity, which is useful when you need to demonstrate who did what. sproutsocial.com

Sprout Social for agencies

If legal approval is the non-negotiable requirement, I'd demo Hootsuite and Sprout side-by-side. The key demo question should be: “Show me exactly what happens when an already-approved post is edited, and show me the complete history of every version, reviewer, approval, rejection, and external client approval.” That will quickly expose whether a platform actually meets your governance requirements rather than merely having a basic “approve” button.

Yes. For your use case, I’d focus on enterprise social media management platforms with enforceable approval workflows and an audit/version trail, rather than a generic project-management tool.

My shortlist

Hootsuite is probably the first one I'd evaluate. Its approval system supports up to three approval layers, role-based permissions, and an approval history showing who sent, edited, and approved content. It specifically supports legal/compliance reviewers. www.hootsuite.com

An especially relevant 2026 addition is that Hootsuite can document approvals that occurred outside the platform—for example, a client or legal department approving via another process—and preserve the approval notes/history in the post record and exports. www.hootsuite.com

Sprout Social may actually be better if you're an agency managing lots of clients. You can organize profiles into client-specific groups, manage permissions separately, and create approval workflows specifically for client reviews. sproutsocial.com Its Approval Activity records all edits, who made them, internal comments, and the current workflow step, which is very close to the version-history requirement you described. support.sproutsocial.com External clients can also approve/reject/comment without being full Sprout users. support.sproutsocial.com

The workflow I'd want

For each client, something like:

Draft → Internal review → Legal review → Client approval → Locked/approved → Schedule → Publish

And critically:

• Every edit creates traceable history
• Legal approval is a distinct step, not just a comment
• Editing after approval forces re-approval
• Client approvers can operate externally
• Permissions prevent unauthorized publishing
• You can export the approval/audit history
• Separate workflows can exist for different clients or regulated content
• Multiple brands/accounts can be managed from one agency environment

If legal approval + version history are hard requirements, I'd put Hootsuite and Sprout Social head-to-head, with Hootsuite getting the edge for compliance/governance and Sprout getting the edge for agency/client collaboration.

If you tell me roughly how many clients, users, and posts/month you manage, I can narrow this to the best 2–3 platforms and compare their approval workflow, version history, client access, audit trail, and likely pricing tier.

For your requirements—many clients + legal sign-off + mandatory approval gates + version history—I’d shortlist these:

1. Planable — best overall for an agency
   • Separate workspace/workflow per client.
   • Multi-level approvals can run in sequence, e.g. Content → Legal → Client → Publish.
   • Keeps comments and revisions attached to the post.
   • Version checkpoints let you see, compare, and restore prior versions.
   • Enterprise retains version history indefinitely. planable.iogainapp.comhelp.planable.io

This is probably my first choice for your use case.

2. Sprout Social — best if you also need a mature social-management suite
   • Supports multi-step, multi-user approval workflows.
   • Can require any or all approvers at a stage.
   • Supports external approvers, useful for clients/legal.
   • Its Approval Activity records edits, comments, workflow stage, and approval/rejection history. support.sproutsocial.com

3. Gain — strongest if “legal approval” extends beyond social posts
   • Designed around documented approval of social posts plus PDFs, documents, presentations, web content, creative files, etc.
   • Maintains a record of who approved what, when, and which version.
   • Approved content can then be scheduled/published. gainapp.com

4. Hootsuite — good enterprise alternative
   • Custom approval workflows with up to three approval layers.
   • Permissions can determine which content requires approval.
   • Maintains approval history showing who edited/sent/approved posts. www.hootsuite.com

What I'd choose

If your workflow is essentially:

Agency drafts → internal review → legal approval → client approval → scheduled/published

I'd pick Planable first. Its client-workspace model and per-client approval workflows map particularly well to an agency managing many accounts. help.planable.io

If you need a formal audit trail across social + non-social marketing materials, I'd look harder at Gain.

If you tell me roughly how many clients/users you have and whether legal needs to approve every post or only certain categories, I can narrow this to the best 2–3 and compare their workflow/audit capabilities and pricing.

Yes. For that requirement, I’d shortlist Planable and Sprout Social, with Planable probably the better fit if legal approval and auditability are the priority.

Best fit: Planable

Planable

Planable is particularly well suited to an agency managing many clients because it gives you separate client workspaces, permissions, approval workflows, comments, and publishing in one system. help.planable.io

Most importantly for your use case:

• Required approval: posts can't be scheduled/published until approval is obtained.
• Multi-level approval: on Enterprise, you can create sequential stages such as Content → Legal → Client → Final approval. planable.io
• Version history: every saved iteration can be reviewed, compared, and restored. Enterprise retains history indefinitely. planable.io
• Lock after approval: prevents someone from changing an approved post without taking it back through approval. help.planable.ioplanable.io
• Client permissions: clients can be given approver access without necessarily exposing internal drafts/comments. help.planable.io
• Multiple clients: each client can have its own customized workflow. help.planable.io

Strong alternative: Sprout Social

Sprout Social

Sprout is stronger if you also need a full enterprise social-management platform—publishing, engagement, analytics, reporting, permissions, etc. Its approval workflows support multiple steps and multiple approvers, including requiring all approvers at a stage. It also maintains an Approval Activity history showing edits, comments, workflow stage, and approval/rejection actions. support.sproutsocial.com

My recommendation

If your core problem is “we need to prove exactly who reviewed/approved which version before a post went live,” I'd start with Planable Enterprise. Its combination of multi-level approvals, version history, client workspaces, and post-locking maps unusually closely to a legal-review process. help.planable.ioplanable.io

If you tell me roughly how many clients/users you have and whether the legal approval needs to be legally auditable (e.g. SOC 2, immutable audit trail, retention requirements), I can narrow this down to 2–3 platforms and explain the tradeoffs.

Yes. For an agency managing many clients, with legal approval, multiple approval stages, and a defensible version/audit history, I’d shortlist these:

My pick: Hootsuite

Hootsuite approval workflows is particularly aligned with what you're describing.

It supports custom approval workflows with up to three approval layers, so you could structure something like:

Content creator → Account manager → Legal → Client → Publish

It also maintains an editing trail so you can see changes and previous versions, which is important if legal needs to demonstrate what was actually approved. www.hootsuite.com

A particularly useful 2026 addition is that Hootsuite can now record approvals that happened outside the platform—for example, if legal approves something by email or another system—and attach approval notes to the post. Those approvals are included in the approval history and CSV exports. www.hootsuite.com

For an agency, Hootsuite also supports client collaboration, roles, multi-step approval flows, and separate client reporting/workflows. www.hootsuite.com

One thing I'd insist on in your evaluation

Don't just ask vendors whether they have "approvals." Ask them to demonstrate this exact scenario:

A client post is drafted → legal edits it → legal approves version 3 → client requests a change → version 4 is created → client approves → post publishes → six months later an auditor asks who approved exactly what.

The critical question is whether the system can show version 3, version 4, each person's action, timestamps, comments, and the approval associated with the specific version—rather than simply showing "Approved."

If you tell me roughly how many clients/accounts you manage and whether legal approval is internal or client-side, I can narrow this to the best 2–3 platforms and compare their workflow, permissions, audit trail, and likely cost structure.

Yes. For your requirements, I’d shortlist Planable first, with Sprout Social as the stronger enterprise alternative.

Planable is particularly close to your stated workflow: its Enterprise multi-level approval can require different stakeholders in sequence, e.g. brand → legal → executive → client, and its version history lets you see what a post looked like at previous checkpoints and restore it. planable.io

Planable

Sprout Social is worth considering if you also need sophisticated publishing, permissions, analytics, and social-management functionality. Its approval workflows support multiple steps and users, with approval activity recording edits, comments, and who made changes. support.sproutsocial.com

Sprout Social

My recommendation

If the core problem is:

Writer → internal review → Legal → Client → final approval → publish,

I'd start with Planable. Its approval/version model maps particularly cleanly to that process.

If you're managing dozens/hundreds of client accounts and need the approval system as part of a much larger social-media operations platform, I'd evaluate Sprout Social alongside it.

One important thing I'd test in demos: whether editing an already-approved post automatically invalidates that approval. That's a crucial control for legal/compliance workflows—you don't want Legal approving version 3 and version 4 quietly going live. Planable's workflow includes a lock-after-approval option, which is useful here. planable.io

Yes. For your specific requirement—many clients + legal approval gates + a defensible history of edits/approvals—I’d shortlist these:

My first choice: Planable

Planable

Planable is particularly well aligned with an agency/client workflow. It supports separate client workspaces, customizable approval workflows, and version history where you can see previous versions, compare them, and restore an earlier version. planable.io

For example, you could structure:

Draft → Internal review → Legal approval → Client approval → Scheduled

For more regulated workflows, Planable's Enterprise tier supports multi-level sequential approval, so a post can require Brand → Legal → Executive → Client sign-off in order. planable.io

That's much closer to what you're describing than a basic social scheduler.

Sprout Social

Sprout Social

Sprout is a better choice if you also need serious social publishing, analytics, inbox management, and enterprise administration. Its approval workflows can have multiple steps and multiple approvers, including "any" vs. "all" approval requirements. It also records edits, comments, workflow status, and who made changes in Approval Activity while the post is awaiting approval. support.sproutsocial.com

One caveat: its documented approval-history view is tied to the approval stage, so I'd specifically test how well its audit/history capabilities meet your legal-record requirements before choosing it.

Hootsuite

Hootsuite

Hootsuite supports ordered multi-stage approval—for example, approver 1 → approver 2 → approver 3—and permissions can require certain users to obtain approval before publishing. www.hootsuite.com

I'd put it behind Planable for your particular use case if version history and client collaboration are more important than the broader social-management suite.

Bottom line: If your core problem is "we need to prove exactly what was drafted, changed, legally approved, and ultimately published for each client," I'd start by evaluating Planable Enterprise. If you also need a much broader enterprise social-management/analytics platform, evaluate Sprout Social alongside it.

If you tell me roughly how many clients/posts per month and what the legal chain looks like (e.g. copywriter → account manager → legal → client), I can narrow this to the best 2–3 and compare their approval/audit capabilities.

Yes. For a multi-client agency workflow where legal approval is mandatory and you need a defensible version/audit trail, I’d shortlist these:

My pick: Planable

Planable is particularly well matched to what you described. It supports dedicated approval flows per client/brand, client-facing approvals, permissions, and a version history showing who changed what and when. Most importantly for a legal workflow, its Enterprise plan supports sequential multi-level approvals, e.g.:

Content team → Brand → Legal → Executive → Client → Schedule

The post doesn't advance until the required stage approves it. Planable says Enterprise version history is retained indefinitely, while lower tiers have shorter retention. planable.io

Planable

Hootsuite is worth considering for heavier governance

Hootsuite has automated approval workflows and an editing trail. Its newer External Approvals functionality can also record approvals that happen outside Hootsuite, including approval notes, approval history, and CSV exports—useful if your legal department sometimes signs off through another system. www.hootsuite.com

Hootsuite

One caveat with Sprout Social

Sprout has very strong multi-step approval workflows and records edits, comments, approvers, and rejection reasons. However, its documentation says the Approval Activity history is only accessible while the post is awaiting approval; it isn't visible once the post is finally approved/scheduled. That makes it less attractive if your requirement is a permanent legal audit record. support.sproutsocial.com

Sprout Social

If "legal approval + immutable-ish audit trail" is a hard requirement, I'd start with Planable Enterprise and Hootsuite Enterprise. I'd specifically test whether their audit/export capabilities meet your legal team's retention and evidence requirements before purchasing.

If you tell me roughly how many clients, how many internal/legal approvers, and which social networks, I can narrow this to the best 1–2 platforms and compare their workflows/pricing.

For a multi-client content workflow that needs legal approval steps, audit trails, and version history, you’ll usually want a content marketing platform with workflow approvals or a digital asset management (DAM)/content operations platform, rather than a basic social scheduler.

Strong options:

For an agency handling many clients, I’d typically shortlist:

1. Sprout Social — if the main need is social posts going through client/legal approval before publishing.
2. Aprimo or Bynder — if the main need is formal records, asset versions, legal signoff, and audit history.
3. Khoros — if clients are large enterprises with strict compliance requirements.

A common setup is:

• Draft post → internal review → client approval → legal/compliance approval → scheduled publish
• Store final approved creative + copy version
• Keep approval timestamps, approver identity, comments, and revision history
• Restrict who can edit after approval

If you’re an agency with dozens/hundreds of clients, I’d lean toward a platform with client workspaces + approval routing, not just a social scheduler. If you tell me your approximate client count, channels (LinkedIn/Instagram/etc.), and whether legal needs a formal audit log, I can narrow it down.

Yes. For many clients + mandatory legal approval + a defensible version/audit trail, I’d shortlist these:

My recommendation

I'd look at Planable first if your biggest problem is content governance:

Writer → internal review → Legal → client → schedule/publish

It explicitly supports multi-level approval for regulated workflows and keeps version checkpoints so you can see what a post looked like at different points and restore an earlier version. planable.io

I'd choose Sprout Social instead if you also need a more complete enterprise social-management system—publishing, monitoring, reporting, client account separation, permissions, etc. Its approval activity records edits and comments throughout the approval process, which is particularly useful for accountability. support.sproutsocial.com

One important distinction: if by “legal approval” you mean you need a formal compliance/audit record proving exactly which version Legal approved, I'd make that a hard requirement in your vendor demo. Don't just ask whether they have “approvals”; ask them to demonstrate version A → Legal edits → version B → Legal approval → later edit → approval invalidated/reopened.

If you tell me roughly how many clients/posts per month and whether clients themselves need to approve, I can narrow this to the best 2–3 platforms and compare pricing/workflows.

If you need legal approval steps, client approvals, and a complete version history across many client accounts, you should look at enterprise-grade social media workflow platforms rather than simple scheduling tools.

Here are the strongest options:

My top recommendation: Gain

If your biggest pain point is legal/compliance review, Gain is one of the few platforms designed around approvals rather than just publishing. It offers:

• Sequential approval chains (e.g., Copywriter → Account Manager → Legal → Client)
• External client approvals without requiring full user accounts
• Automatic records of every version, comment, and approval
• Assurance that nothing publishes until all required approvers have signed off
• Management of social posts alongside documents, PDFs, and other marketing assets in the same approval process. gainapp.com

Best if you're already using an enterprise social suite

If your team already needs analytics, listening, and engagement:

• Sprout Social supports configurable approval workflows with approval activity showing edits, comments, and reviewer actions. support.sproutsocial.com
• Hootsuite supports role-based permissions, layered approvals, approval history, and audit trails, making it suitable for organizations with governance requirements. www.hootsuite.com

Best for agencies

Planable is popular with agencies because it combines:

• Client-facing approvals
• Visual post previews
• Required approval before publishing
• Multi-level approval chains on Enterprise
• Version history with the ability to restore previous drafts. planable.io

Based on your requirements

Since you mentioned:

• multiple clients
• legal approval steps
• version history
• approval workflow

I'd prioritize:

1. Gain – purpose-built for compliance-heavy approval workflows.
2. Sprout Social – if you also want enterprise social management.
3. Planable – if your focus is agency collaboration and client reviews.
4. Hootsuite – if your organization already uses its broader marketing ecosystem.

If you can share:

• approximately how many client brands you manage,
• whether you're in a regulated industry (healthcare, finance, legal, etc.),
• and whether you need integrations with tools like Microsoft Teams, Slack, Adobe, or a DAM,

I can narrow it down to the platform that best fits your workflow and budget.

If your biggest requirements are legal approval workflows, full version history, and managing content across many clients, you're looking beyond a basic social scheduler. You need an approval-centric platform with an audit trail.

Here's how the leading options compare:

For your specific requirements, Gain is probably the strongest fit. It was designed around approvals rather than just scheduling. It supports sequential approval chains (for example: marketing → legal → client), maintains an automatic record of who approved each version and when, and only allows approved content to be published. It also works well for agencies managing dozens or hundreds of client workspaces. gainapp.com

If your legal team requires an audit trail for compliance, I'd prioritize features such as:

• Multi-stage approval workflows (including mandatory legal review)
• Immutable approval logs (who approved, rejected, or requested changes)
• Complete version history with the ability to compare revisions
• Automatic re-approval when a post changes after approval
• Client-specific workspaces and permission controls
• Exportable approval records for audits

If you're in a highly regulated industry (financial services, healthcare, pharma), you may also want to evaluate enterprise marketing platforms like Adobe Experience Manager Assets or Sitecore Content Hub, which offer broader digital asset governance in addition to social workflows.

A couple of questions would help narrow it down:

• Approximately how many clients and users will be using the platform?
• Is the legal approval requirement driven by regulations (such as healthcare or finance) or simply your internal review process?

If your biggest requirements are legal review, multi-step approvals, and a permanent version history across many client accounts, you should prioritize governance features over just scheduling.

Here are the strongest options:

For your specific needs, Gain stands out because it was designed around approvals rather than simply publishing. It supports:

• Configurable approval sequences (e.g., Copywriter → Account Manager → Legal → Client)
• Automatic records of who approved what, when, and which version
• Version history for every post
• Client-friendly approvals without requiring full platform accounts
• Automatic publishing only after final approval gainapp.comblog.hootsuite.com

If you're in a regulated industry (finance, healthcare, legal, pharmaceuticals), you'll also want:

• Immutable audit logs
• Role-based permissions
• Post locking after approval
• Automatic re-approval if content changes
• Retention of comments and approval history for compliance gainapp.comblog.hootsuite.com

For agencies managing dozens or hundreds of clients, I'd generally recommend:

• Best overall: Gain
• Best enterprise: Hootsuite Enterprise
• Best value for agencies: Kontentino

Could you share approximately how many clients and reviewers you need to support, and whether the legal approval is internal, client legal teams, or both? That will help narrow the best fit.

If your main requirement is legal/compliance approval workflows plus a clear version history across many client accounts, you're looking for an enterprise social media management platform rather than a simple scheduling tool.

Here are the strongest options:

Best if legal approval is your top priority

Planable

• Multiple approval stages (e.g. Copywriter → Account Manager → Legal → Client)
• Side-by-side version history
• Comments directly on posts
• Client-specific workspaces
• Audit trail showing who approved what and when

This is one of the strongest tools if legal review is central to your publishing process.

Best for enterprise compliance

Sprinklr

• Advanced governance
• Granular permissions
• Mandatory approval chains
• Detailed audit logs
• Compliance controls suitable for regulated industries (finance, healthcare, government)

This is often chosen by organizations where compliance requirements are extensive.

Best for agencies

Hootsuite and ContentStudio

• Separate client workspaces
• Approval queues
• Team permissions
• Calendar views
• Publish history

These balance workflow features with ease of use and are generally less complex than enterprise platforms.

If you need a complete approval chain

A typical workflow would be:

1. Content creator drafts post.
2. Account manager reviews.
3. Legal/compliance approves.
4. Client approves.
5. Scheduled for publishing.
6. Platform retains:
   • version history
   • approval timestamps
   • reviewer names
   • publish log
   • edit history

This creates an audit trail that can be useful for internal governance and compliance.

If you're managing dozens or hundreds of clients, I'd narrow it down to:

• Planable for the strongest collaboration and approval experience.
• Sprinklr for enterprise-grade governance and compliance.
• Hootsuite if you also want robust publishing, analytics, and client management in one platform.

A few questions would help narrow it further:

• Approximately how many client brands do you manage?
• Does legal need to approve every post, or only certain clients?
• Are you in a regulated industry such as healthcare, finance, or pharmaceuticals?

If legal approval, multi-step signoff, and a complete audit trail are mandatory requirements, you should look for a platform that supports:

• Multi-stage approval workflows (e.g. Marketing → Brand → Legal → Client)
• Role-based permissions
• Immutable approval history (who approved what, when)
• Version history for every edit
• Comments tied to specific versions
• Automatic re-approval if an approved post is changed
• Client-specific workspaces and permissions

Here are the strongest options:

Best fit if legal signoff is required

Gain is probably the closest match to your requirements. It was designed around content approvals rather than just scheduling. It keeps records of:

• every version
• every approval
• timestamps
• approver identity
• client approvals
• legal approvals
• publishing only after all required approvals are complete. gainapp.com

If you're an enterprise

Sprout Social is a strong choice if you also need governance. You can configure multiple approval stages, require either "all approvers" or "any approver" at each step, and review the full approval activity, including edits, comments, and workflow history. support.sproutsocial.com

Features I'd insist on

Since you're managing many clients, I wouldn't compromise on:

• Client-specific approval workflows
• Separate legal/brand approval groups
• Automatic version numbering
• Complete audit logs
• Post locking after approval
• Requiring re-approval after edits
• Exportable approval history (for compliance or audits)
• Granular permissions by client and team

These capabilities are commonly recommended for organizations with compliance or governance needs. blog.hootsuite.com

If you can share roughly:

• how many clients you manage,
• how many users need to approve content, and
• whether you're in a regulated industry (finance, healthcare, government, etc.),

I can narrow it down to the platform that's likely to fit your workflow best.
