For a multi-client agency where legal approval and a defensible version/audit history are requirements, I’d shortlist these:

What I'd look at first

Hootsuite Enterprise is particularly relevant if you need formal governance. It supports multiple approval tiers, role-based permissions, approval history, and audit exports. It also added the ability to document approvals that happened outside Hootsuite, with approval notes captured in the history. Hootsuite Help Center Hootsuite

hootsuite.com

Sprout Social Advanced is another strong fit for an agency. Its workflows can have multiple steps with multiple approvers, and its Approval Activity records edits, comments, workflow status, and who made changes. Its audit trail also records events such as post creation, editing, and approval. External approvers are supported on Advanced. Sprout Social Support Sprout Social Support Sprout Social Support

Planable Enterprise is worth testing if version history itself is the critical requirement. Planable says every saved post creates a version checkpoint, with the ability to compare and restore previous versions; Enterprise retains that history indefinitely. Its Enterprise workflow supports sequential stages such as brand → legal → executive → client. Planable

planable.io

For your specific workflow

I'd structure it roughly as:

Draft → Internal review → Legal → Client → Final approval → Scheduled/published

And make these non-negotiable requirements when evaluating vendors:

• Approval cannot be bypassed without being logged.
• Editing an approved post should invalidate/retrigger approval.
• Every revision should retain author + timestamp.
• Legal approval should be distinguishable from ordinary comments.
• External client approvals should be captured in the audit record.
• You should be able to export the approval history.
• Separate workflows/permissions should be possible for each client.
• The approval should apply to the actual platform-specific post, including creative, links, captions and first comments—not merely a copy of the text.

That last point is important: some platforms' approval systems are considerably more sophisticated than simply putting a "Legal approved" checkbox on a content calendar. Hootsuite, for example, describes editing trails and approval history, while Planable explicitly creates version checkpoints. Hootsuite Planable

If you tell me roughly how many clients/users you have (e.g. 20 clients, 50 staff) and whether legal is internal or an outside law firm, I can narrow this to 2–3 platforms and compare the actual workflow and pricing tiers.

Sprout Social Advanced is another strong fit for an agency. Its workflows can have multiple steps with multiple approvers, and its Approval Activity records edits, comments, workflow status, and who made changes. Its audit trail also records events such as post creation, editing, and approval. External approvers are supported on Advanced. support.sproutsocial.com support.sproutsocial.com support.sproutsocial.com

Planable Enterprise is worth testing if version history itself is the critical requirement. Planable says every saved post creates a version checkpoint, with the ability to compare and restore previous versions; Enterprise retains that history indefinitely. Its Enterprise workflow supports sequential stages such as brand → legal → executive → client.

For your requirements—multiple clients, legal sign-off, controlled publishing, and a defensible history of who changed/approved what—I’d look primarily at enterprise social-media management platforms rather than a basic content calendar.

Strong candidates

• Hootsuite — particularly relevant if legal/compliance needs to be part of the workflow. It supports up to three approval layers, role-based permissions, approval history, and an editing trail showing changes and previous versions. Its Enterprise tier can also document approvals that happened outside Hootsuite, with notes recorded in the approval history and CSV exports. Hootsuite Hootsuite Help Center Hootsuite

hootsuite.com

• Sprout Social — strong for agency/client workflows. You can create multi-step approval workflows, assign different approvers, and include external approvers. Its Approval Activity records edits, comments, workflow status, and who made changes; it also offers a customer audit trail. Sprout Social Support Sprout Social Support

sproutsocial.com

• Sked Social — worth evaluating if your legal/compliance requirement is particularly strict. Its enterprise offering advertises multi-step approval chains, per-post audit logs, immutable activity logs, exports, RBAC/SSO, and routing by region/channel/content type. Sked Social

skedsocial.com

• Maeve Social — interesting if true version-specific approval history is your biggest concern. Its workflow records the version associated with an approval, while subsequent edits create a new version and preserve the earlier decision against the previous version. It also supports internal and no-login client reviews. Maeve Social

What I'd specifically test in a demo

Don't just ask whether a product has "approvals." Give the vendor this scenario:

Writer creates post → internal reviewer edits → legal approves → client approves → writer makes a change → legal approval must become invalid → new version goes back through legal → final publisher schedules it.

Then verify that the system can show:

• exactly which version legal approved
• every change between versions
• who made each change and when
• rejection reasons/comments
• approval order and timestamps
• client-specific permissions/workspaces
• whether approval is automatically invalidated after an edit
• exportable audit records
• SSO/RBAC and retention controls

For a multi-client agency, I'd shortlist Hootsuite Enterprise and Sprout Social Advanced/Enterprise first, then compare them against Sked if your legal/audit requirements are unusually stringent. The key distinction is that "approval workflow" and version-linked approval/audit history aren't necessarily the same thing. Sprout Social Support Hootsuite Help Center

If you tell me roughly how many clients/users you have and whether clients need to log in to approve, I can narrow this to 2–3 platforms and compare their workflows and likely fit.

For a multi-client agency workflow where legal approval, audit trails, and version history matter, you’ll want more than a normal social scheduler. Look for a platform with:

• Multi-client workspaces (each client isolated)
• Approval chains (creator → account manager → legal → client)
• Locked approved versions (so nobody accidentally edits the approved copy)
• Revision history (who changed what and when)
• Audit logs (proof of approval)
• Role-based permissions
• Approval before publishing gates

Platforms that fit this use case:

A few workflow patterns:

If legal must approve before anything goes live

Prioritize:

1. Sprout Social
2. Hootsuite
3. Planable

These are closer to enterprise governance systems.

If you are an agency managing dozens of clients

Prioritize:

1. Sendible
2. Planable
3. SocialPilot

Agency-oriented tools commonly emphasize client workspaces and approval flows. Tareno SocialPilot

If your biggest risk is “which version did legal approve?”

Make sure the tool can answer:

• “Show me the exact post version approved.”
• “Who approved it?”
• “When did they approve it?”
• “What changed afterward?”
• “Can we prove the published post matches the approved one?”

Some platforms explicitly preserve approval snapshots and revision comparisons; for example, Postoria describes approval snapshots containing the social versions, media, captions, and links, with comparison between review rounds. Postoria

For a many-client agency with legal sign-off, I would shortlist:

• Enterprise/regulatory: Sprout Social or Hootsuite
• Agency workflow: Planable or Sendible
• Heavy client review + version tracking: Ovia or similar approval-first platforms Ovia

If you tell me roughly how many clients, which networks (LinkedIn/Instagram/etc.), and whether “legal” means internal counsel vs client legal teams, I can narrow this to 2–3 options.

Yes. For many clients + legal approval + version history, I’d focus on agency-oriented social publishing platforms rather than a generic project-management tool.

My shortlist

• planable.io — probably my first choice for your use case. It supports required approvals for client work, and its Enterprise tier supports multi-level approval, such as brand → legal → executive → client. It also keeps version checkpoints so you can compare/restore earlier versions. Planable
• hootsuite.com — strongest if governance/compliance is the priority. It supports up to three approval layers, role-based permissions, approval history, and an audit trail. It also added the ability in 2026 to document approvals that happened externally, with those approvals captured in the approval history and CSV exports. Hootsuite Hootsuite
• sproutsocial.com — strong enterprise alternative. Its workflows can have multiple steps and multiple approvers, with approval activity showing edits, comments, workflow stage, and who made changes. It also offers customer audit-trail exports. Sprout Social Support
• postoria.io — interesting if easy client review is particularly important. It captures a read-only snapshot of the actual social-network versions being reviewed and preserves approval history between review rounds. External reviewers don't need an account. Postoria

What I'd choose

If your workflow is something like:

Writer → Account Manager → Legal → Client → Schedule

I'd lean Planable if you want the best combination of client collaboration + version control + structured approvals.

If the requirement is more like:

"We need to be able to prove exactly who approved which version, when, and prevent unauthorized changes from going live."

I'd lean Hootsuite or Sprout Social, with Hootsuite getting the edge for governance/audit-oriented workflows. Hootsuite Hootsuite

One important thing to test in demos: what happens when an already-approved post is edited? You want the approval to become invalid and the post to go back through the required approval chain—not simply remain marked "approved." That is critical for legal sign-off.

If you tell me roughly how many clients/accounts you manage and whether legal approval is internal or performed by each client, I can narrow this to the best 2–3 platforms and compare pricing/workflows.

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

1. planable.io — best fit for an agency

• Separate workspace for each client.
• Required approvals prevent publishing before sign-off.
• Multi-level approval can enforce a sequence such as content team → legal → client.
• Version history lets you see previous versions and restore them.
• You can customize approval workflows per client workspace. Planable Planable
• Particularly good if the core problem is content production + client/legal approval, rather than enterprise social listening.
• hootsuite.com — best if you also need a mature social-management suite

• Supports up to three approval layers with designated approvers.
• Maintains approval history and an editing trail showing changes/previous versions.
• Specifically supports workflows involving legal/compliance reviewers.
• Has agency-oriented multi-client functionality. Hootsuite Hootsuite
• sprinklr.com — best for large, highly regulated enterprises

• More of an enterprise customer-experience/social platform than a straightforward content calendar.
• Supports approval workflows designed around regulatory/compliance requirements. Sprinklr
• I'd consider it if you're dealing with large volumes, extensive compliance controls, multiple departments, and formal audit requirements.

My recommendation

If you're an agency managing dozens/hundreds of client accounts, I'd start with Planable Enterprise. Its workflow maps unusually well to what you're describing:

Draft → internal review → legal approval → client approval → locked/approved → publish

Planable explicitly supports multi-level approval for workflows involving team, clients, internal stakeholders, and legal, and Enterprise retains version history indefinitely. Planable

If you tell me roughly how many clients/posts per month and whether legal approval is required on every post or only certain clients/campaigns, I can narrow this to 2–3 platforms and compare them on workflow, audit trail, permissions, client access, and price.

Yes. For your requirements, I’d look first at Planable.

It’s particularly well suited to an agency managing many clients because it combines client workspaces, approval workflows, legal/internal review, and version history in one system. Planable Planable

Best fit: Planable

You can structure a workflow such as:

Content creator → Account manager → Legal → Client → Scheduled/published

Planable's Enterprise plan supports multi-level approvals, so a post can move through multiple stakeholders in a defined sequence. It also lets you lock content after approval so that an approved post can't quietly be changed afterward. Planable Planable

For version control, Planable creates a version checkpoint whenever a post is saved, allowing you to see previous versions, compare them, and restore an earlier version. Enterprise retains version history indefinitely. Planable

For multiple clients, you can have a separate workspace for each client, with their own content, permissions, approval process, and connected social accounts. Planable

Another strong option: Sprout Social

Sprout Social is worth considering if you also need a more comprehensive social-management/analytics platform.

Its approval workflows support multiple steps and multiple approvers, and its Approval Activity records edits, comments, workflow status, and who made changes. It also has audit-trail events for actions such as creating, editing, approving, and publishing posts. Sprout Social Support Sprout Social Support

My recommendation

If the core problem is "nothing gets published until Legal and the client approve the correct version," I'd choose Planable. If you're looking for an all-in-one enterprise social platform where approvals are one component alongside analytics, listening, engagement, and reporting, I'd lean Sprout Social.

If you tell me roughly how many clients/users you have and whether Legal needs to approve before or after the client, I can narrow this down to 2–3 platforms and map the exact workflow you'd want.

Yes. For that workflow, I’d look at Planable first, with Sprout Social as the stronger alternative if you also need a more full-scale social-management platform.

Best fit: Planable

planable.io is particularly well suited to agencies managing many clients because you can create separate approval flows for each client/brand, have client stakeholders approve content, and keep the discussion attached to the actual post. Planable Planable

The important part for your use case is that Planable has:

• Required approvals — a post can't proceed until the designated approver signs off.
• Multi-level approvals on Enterprise — useful for something like Content → Brand → Legal → Client. Planable
• Version history — saved versions can be compared and restored, with Enterprise retaining history indefinitely. Planable
• Client-specific workflows and permissions.
• Lock after approval, preventing someone from quietly changing an approved post afterward. Planable
• A visual calendar/feed where clients can review the actual post rather than approving a spreadsheet row.

Strong alternative: Sprout Social

sproutsocial.com is better if you're looking for a broader enterprise social-management system.

Its approval workflows support multiple steps and multiple approvers, including configurations where all designated people must approve. It also records edits, comments, workflow status, and approval activity while a post is awaiting approval. Sprout Social Support

For example:

Account manager → Client → Legal → Schedule

Sprout also supports external approvers on its Advanced plan, which could be useful if your clients' legal teams don't need full platform accounts. Sprout Social Support

My recommendation

If your central problem is "nothing gets published until the right client/legal people approve the exact version," I'd choose Planable. Its workflow and version-control model maps very closely to that requirement. Planable

If you're managing dozens/hundreds of client accounts and need serious publishing, analytics, permissions, and compliance controls in addition to approvals, I'd lean toward Sprout Social.

If you tell me roughly how many clients/users you have and whether "legal approval" needs to be a formal auditable sign-off, I can narrow it down to 2–3 platforms and explain which one I'd buy.

Yes. For a multi-client agency where posts need legal approval and a defensible version/audit history, I’d shortlist these:

• Sprout Social — probably the safest all-around choice. It supports client-specific groups/permissions and multi-step approval workflows, including internal and external approvals. Its Approval Activity records edits, comments, workflow steps, and who made changes; it also has customer-facing audit logs. Sprout Social Support Sprout Social Sprout Social

sproutsocial.com

• Hootsuite — strong if legal/compliance is a formal gate. It supports up to three approval layers, role-based permissions, approval history, and an editing trail. Its 2026 update also added a way to record approvals that happened externally, including approval notes and CSV audit history. Hootsuite Hootsuite

hootsuite.com

• Planable — worth considering if the client review experience is more important than deep enterprise governance. Current comparisons specifically highlight it for its approval interface, while Kontentino is stronger for complex agency approval structures. Kontentino
• Warrant — I'd investigate this if by "legal approval" you mean actual regulatory/legal compliance, rather than simply having a lawyer click Approve. It is specifically designed around marketing compliance, with disclosures, regulations, versioning, approval workflows, and audit trails. Warrant

hellowarrant.com

What I'd choose

For your requirements, I'd rank them:

1. Sprout Social → best overall agency + client + approval/audit combination
2. Hootsuite → best if governance/compliance is particularly important
3. Warrant → best if you're in a heavily regulated environment and legal review is central
4. Planable/Kontentino → best if the workflow is primarily client content approval

The key requirement I'd insist on in a demo is version-bound approval: if Legal approves Version 4, then someone changes the caption afterward, the system should invalidate that approval and require Version 5 to be approved again. That's much more valuable legally than merely having a generic "approved" status. Kontentino

If you tell me how many clients/users you have and what industry the clients are in (e.g. financial, healthcare, pharma, legal, general brands), I can narrow this down to 2–3 platforms and compare their approval workflow, version history, audit trail, client access, and likely cost.

Yes. For a multi-client agency where posts need formal legal approval and a defensible version history, I’d shortlist these:

My first choice: Planable

planable.io is particularly close to what you're describing.

You can give each client their own workspace and configure different approval rules per client. For a regulated client, for example, you could have:

Content team → Account manager → Legal → Client → Scheduled

Planable's Enterprise multi-level approval workflow supports sequential stages, and it can lock approved posts so edits require the approval process to be revisited. Planable Planable

The other important piece for you is version history: Planable creates checkpoints as posts are saved, allowing previous versions to be reviewed and restored. Planable Planable

It also supports separate client workspaces, permissions, internal discussions, client approvals, and managing multiple brands/clients from the agency environment. Planable Planable

If legal/compliance is the primary concern

I'd also look seriously at Hootsuite Enterprise. Its approval workflow supports multiple tiers, role-based permissions, post locking after approval, and an audit trail of actions—features explicitly aimed at enterprise/compliance workflows. Social Media Dashboard

The distinction I'd make is:

• Planable → better if you want a pleasant agency + client collaboration/approval experience.
• Hootsuite → better if you're a larger organization where governance, permissions, auditability, and enterprise social management are paramount.
• Suits → worth investigating if the key requirement is that an approval is tied to the exact version that was reviewed; it records version changes and resets approval when an approved card is edited. Suits™

For your specific requirement, I'd start with Planable and Hootsuite side-by-side. The critical demo question isn't just "does it have approvals?" Ask them to demonstrate: Legal approves v3 → someone edits the caption → system shows v4 → v3's legal approval remains preserved → v4 cannot publish until legal approves again. That's the behavior you want for a genuinely defensible audit trail.

The distinction I'd make is:

Yes. For that requirement, I’d look at content/social workflow platforms rather than a basic scheduler.

My top pick: Planable

planable.io is particularly well matched to an agency managing many clients because it supports:

• Separate client workspaces with customized approval processes for each client. Planable Planable
• Multi-step approvals, e.g. Writer → Account Lead → Legal → Client → Publish. Multi-level approval is available on Enterprise. Planable Planable
• Required approvals, so a post can't be published until the required sign-off happens. Planable
• Version history showing previous versions, who changed them, and allowing restoration. Enterprise retains version history indefinitely. Planable
• Internal vs. client-facing comments, useful when your team needs to discuss legal/strategy issues without the client seeing everything. Planable
• Locking after approval, which helps prevent someone from changing an approved post without sending it through approval again. Planable

Two alternatives worth considering

Sprout Social is stronger if you also need sophisticated social listening, engagement, analytics, and publishing. Its approval workflows support multiple steps/users, and its Approval Activity records edits, comments, workflow status, and who performed actions. Sprout Social Support

Hootsuite is another strong enterprise option. It supports up to three approval layers, including legal/compliance reviewers, and maintains approval history. It also added the ability in 2026 to record external approvals and approval notes in an audit-ready history. Hootsuite Hootsuite

What I'd choose

If your primary problem is:

"We manage lots of clients, and every post needs a defensible trail from draft → revisions → legal approval → client approval → publication."

I'd start with Planable Enterprise. It seems closest to the workflow you're describing, particularly because multi-level approvals + version history + client workspaces are core features rather than workarounds. Planable Planable

If you tell me how your approval chain works (e.g. copywriter → account manager → legal → client) and roughly how many clients/users, I can narrow it down between Planable, Sprout, Hootsuite, and a few more enterprise options.

For a multi-client environment where legal approval, auditability, and version history matter, you’ll want more than a basic social scheduler. Look for:

• Multi-stage approval workflows (creator → internal reviewer → legal/compliance → client)
• Version history tied to the approved asset (so you can prove exactly what was signed off)
• Approval timestamps and user audit logs
• Role-based permissions (who can edit vs. approve vs. publish)
• Client workspaces or portals
• Ability to prevent publishing until approval is complete Kontentino Social Media Dashboard

Platforms worth evaluating:

How I’d narrow it down

• Agency with dozens/hundreds of clients: Start with Planable, Kontentino, or Ovia. They are designed around client review loops rather than only internal approvals. Kontentino Ovia
• Highly regulated clients requiring legal signoff records: Evaluate Sprout Social, Hootsuite Enterprise, or a compliance-focused platform like Warrant. Hootsuite Warrant
• Need proof in disputes (“who approved this exact caption/image?”): prioritize tools where approval is attached to a specific version, not just a comment thread. Kontentino

A few questions would change the recommendation:

1. Are you an agency managing external clients, or an in-house team managing many brands?
2. Do legal reviewers need to approve every post, or only certain categories (claims, promotions, regulated topics)?
3. Do clients need to approve through a portal/link without creating accounts?

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

• planable.io — my first choice for an agency. It supports separate workspaces/workflows per client, required approvals, and Enterprise-level multi-stage approvals such as brand → legal → executive → client. It also keeps version checkpoints so you can compare/restore prior versions. Planable Planable Planable
• hootsuite.com — better if you need a more enterprise-oriented social-management platform. It supports up to three approval layers, role-based permissions, approval history, and workflows involving legal/compliance. Hootsuite Social Media Dashboard
• apaya.com — worth evaluating for heavily regulated clients. It specifically positions itself around enterprise/legal review and provides content history and approval trails, with per-client approval configurations. Apaya Apaya

What I'd choose

If you're a marketing/social agency managing dozens of clients, I'd start with Planable. The key advantage is that you can make the workflow client-specific rather than forcing every client through the same process—for example:

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

while a less regulated client could simply use:

Draft → Internal approval → Client approval → Scheduled

Planable explicitly supports different approval layers per workspace/client and keeps the editing history attached to the content. Planable Planable

If by "legal approval" you mean you need a formal, auditable record showing exactly which version was approved, by whom, when, and ensuring the approved version cannot be silently changed before publishing, I'd put Hootsuite and Apaya into the evaluation alongside Planable.

If you tell me roughly how many clients/users you have and whether you manage social posts only or also ads, blogs, email, and other marketing content, I can narrow this to the best 2–3 platforms and compare their approval/version-control capabilities.

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

• Planable — best fit for an agency/client workflow. You can create separate workspaces per client, assign roles/permissions, route posts through approval stages, and keep version history showing who changed what and when. Its Enterprise tier supports multi-level sequential approvals, which could be configured as Creator → Account Manager → Legal → Client → Publish. Planable Planable

• Hootsuite — best if governance/compliance is the priority. It supports up to three approval layers, role-based publishing permissions, approval history, and an editing trail. Hootsuite specifically describes legal/compliance reviewers as a use case. Hootsuite Social Media Dashboard

hootsuite.com

• Sprout Social — strong enterprise alternative. Its approval workflows support multiple steps/users, including "all approvers" vs. "any approver," and Approval Activity records edits, comments, workflow status, and approvals. It also offers an audit-trail export. Sprout Social Support

sproutsocial.com

My recommendation

For an agency managing lots of clients, I'd start with Planable. Its client-specific workspaces and content-centric approvals make it particularly well suited to:

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

The version history is especially important: Planable says each saved post gets a version checkpoint, allowing you to compare and restore previous versions; Enterprise retains that history indefinitely. Planable

If your requirement is more formal compliance/audit governance than client collaboration, I'd put Hootsuite ahead of Planable.

If you tell me roughly how many clients, users, and posts/month you have—and whether legal approval is internal legal staff or an external law firm—I can narrow this to the best 2–3 platforms and compare pricing/workflows.

For a multi-client environment where posts need legal/compliance approval, audit trails, and version history, you’ll want a social media management platform with workflow approvals, not just a scheduler.

Good fits:

For your specific requirement (legal approval steps + many clients), I’d prioritize:

1. Gain — if legal/compliance auditability is the biggest concern. It treats approvals as a formal record rather than just a “thumbs up.” Gain
2. Hootsuite Enterprise — if you have corporate governance, multiple departments, or regulated clients. Hootsuite
3. Planable or Ovia — if your main challenge is agency workflow and getting clients to approve quickly. Kontentino Ovia

Before choosing, verify these features:

• Separate workspace/client areas
• Custom approval chains (creator → account manager → legal → client)
• Required approvers (not optional comments)
• Version locking (approval tied to a specific version)
• Full audit log (who approved, rejected, changed, and when)
• Permission controls by client/team member
• Exportable approval history for compliance records

If you’re an agency managing dozens/hundreds of client accounts, I’d lean toward Gain or Planable. If you’re managing regulated industries (healthcare, finance, government, etc.), I’d look harder at Hootsuite Enterprise or a dedicated governance workflow tool.

Yes. For a multi-client agency where legal/compliance approval, auditability, and post/version history are requirements, I’d shortlist Sprout Social and Hootsuite, with Sprout Social as my first choice.

Best fit: sproutsocial.com

Sprout is particularly well suited to an agency setup:

• Client-specific workspaces/groups: You can separate clients and control who has access to each social profile. Sprout Social
• Multi-step approvals: You can create workflows with multiple steps and multiple approvers, including an "all approvers" requirement. Sprout Social Support
• External/client approvers: Advanced supports up to three external approvers, so clients or legal reviewers don't necessarily need full platform access. Sprout Social Support
• Change history: Approval Activity records edits, comments, workflow status, and who made changes while the post is awaiting approval. Sprout Social Support
• Audit trail: Sprout maintains customer-facing audit logs documenting user activity and actions, which is useful when you need to demonstrate who did what. Sprout Social
• Agency-oriented permissions and calendars: It specifically supports agency workflows, separate client environments, permissions, shared calendars, and client collaboration. Sprout Social

A workflow could look like:

Writer → Account Manager → Legal → Client → Scheduled/Published

And you can make certain clients require a different chain, e.g.:

Writer → Internal Compliance → Client Legal → Client Marketing → Publish

Strong alternative: hootsuite.com

Hootsuite is also strong for this use case. It supports up to three approval layers, custom approval workflows, role-based permissions, and an approval history showing who edited, sent, or approved content. Hootsuite

One particularly relevant recent feature is documented external approvals: Hootsuite can record an approval that happened outside the platform, including notes, and retain it in approval history and CSV exports. Hootsuite

What I'd choose

If "legal approval" is a hard requirement rather than simply client sign-off, I'd start with Sprout Social Advanced and Hootsuite Business/Enterprise in a side-by-side demo. The key thing I'd test is whether their version history meets your legal team's definition of an auditable record—not just whether they show an "approved" badge.

If you tell me how many clients/users you have and whether legal is internal or each client's outside legal team, I can narrow this down to 2–3 platforms and map the exact approval workflow you'd want.

For a multi-client environment where posts need legal approval steps, audit trails, and version history, you’ll want more than a normal social scheduler. Look for a platform with:

• Multi-stage approvals (creator → account manager → legal/compliance → client)
• Role-based permissions
• Locked approved versions (changes force re-approval)
• Timestamped approval history
• Client workspaces/brand separation
• Comments attached to the exact post/version
• Exportable audit records

Good fits:

My shortlist by scenario

• Large agency + regulated clients (healthcare, finance, legal): Gain or Hootsuite
• Marketing agency managing dozens/hundreds of clients: Gain or Ovia
• Need clients to approve without creating accounts: Ovia, Postoria, or Gain Ovia Postoria Gain
• Need a compliance-style audit trail: Gain or Hootsuite Gain Hootsuite

A typical workflow you’d configure would look like:

1. Copywriter creates draft
2. Designer attaches creative assets
3. Internal review
4. Legal/compliance approval
5. Client approval
6. Version locked
7. Scheduled publishing
8. Archive retains final approved version + approval record

If you’re managing many clients as an agency, I’d start by evaluating Gain vs. Ovia; if this is an enterprise marketing department with strict governance, I’d look hardest at Hootsuite or Gain. Ovia Gain Hootsuite

I can also help compare these against your current stack (e.g., Sprout, Asana, Monday, Jira, Adobe, Canva, SharePoint) if you have one.

Yes. For a multi-client agency where legal approval and an auditable version trail are requirements, I’d shortlist these:

1. planable.io — probably the best fit

Planable is particularly strong for the workflow you described:

Draft → internal review → legal → client → schedule/publish

• Multi-level approvals: you can create sequential approval stages, e.g. content team → legal → client. Planable
• Version history: saved versions let you see what changed, compare versions, and restore an earlier version. Enterprise retains history indefinitely. Planable Planable
• Client separation: dedicated workspaces for each client/brand, with internal discussions that aren't exposed to clients. Planable
• Approval permissions: only designated people can approve, which is useful when legal sign-off has to be explicit. Planable
• Auditability: activity/version history can show who did what and when, including approval activity. Planable
• It is built specifically around agency/client content workflows rather than just being a generic social scheduler. Planable

For example, you could configure:

Copywriter → Account Manager → Legal → Client → Auto-schedule

That's very close to the workflow you described.

2. sproutsocial.com — better if you need a larger social-management suite

Sprout has multi-step/multi-user approval workflows, client-specific groups and permissions, and agency-oriented features. Sprout Social Support Sprout Social

Its Approval Activity records edits, comments, workflow stage, and who made changes while a post is awaiting approval. Sprout Social Support

I'd favor Sprout if you also need robust publishing, social listening, engagement, analytics and reporting across a large operation. For pure content approval/version control, I think Planable is the cleaner fit.

My recommendation

If your primary requirement is "we manage many clients and absolutely cannot publish a post without the right legal/client sign-offs, while retaining a defensible history of revisions", I'd start with Planable Enterprise.

If you're building a much broader enterprise social-media operation, evaluate Sprout Social alongside it.

One important distinction: if by "legal approval" you mean regulated-industry compliance with formal records retention, e-signatures, immutable audit logs, legal holds, etc., I'd evaluate the compliance/audit capabilities separately rather than assuming a social-media platform's version history satisfies your legal-record requirements.

For managing many clients with legal approval steps, auditability, and version history, you’ll want a social media management platform with multi-stage approval workflows, not just a scheduler. The key features to look for are:

• Client-specific workspaces or brand separation
• Draft → internal review → legal/compliance → client approval → publish workflow
• Approval tied to a specific version (so edits after approval trigger re-review)
• Full audit trail: who changed what, who approved it, and when
• Role-based permissions (creator, editor, legal reviewer, client approver)
• Commenting/markup directly on the post or creative
• Exportable approval history for disputes or compliance reviews

Platforms worth evaluating:

A typical agency/legal workflow would look like:

1. Social team drafts post + attaches creative
2. Account manager reviews
3. Legal/compliance reviews only posts requiring it
4. Client approves final version
5. Platform locks the approved version
6. Post publishes
7. Approval record remains searchable

For your use case (“many clients” + “legal approval steps”), I’d narrow the shortlist to:

• Agency-focused: Planable, Ovia, Kontentino
• Enterprise/compliance-heavy: Sprout Social, Hootsuite, Warrant
• If legal sign-off is a formal requirement: prioritize tools that lock approvals to versions rather than just recording a thumbs-up

A few questions would change the recommendation:

1. Are you an agency managing external clients, or an in-house team managing multiple brands?
2. Do you need approval from client legal teams, or only your internal legal/compliance team?
3. Roughly how many clients/accounts (10, 100, 1,000+)?

For your use case—many clients + legal/compliance approval + auditable version history—I’d shortlist these:

My pick: Hootsuite

hootsuite.com is probably the safest starting point if legal sign-off and auditability are the priority.

It supports multi-level approval chains, role-based permissions, approval history, and an editing trail showing changes and previous versions. More importantly, its 2026 update allows external approvals/bypassed approvals to be documented in the approval history and CSV exports, which is useful if your legal team sometimes approves outside the platform. Hootsuite Hootsuite

Strong alternative: Sprout Social

sproutsocial.com is particularly attractive if you're running an agency with separate environments for lots of clients. It supports separate client accounts, roles/permissions, multi-step approval workflows, and external approvers. Sprout Social Sprout Social Support

One caveat: Sprout's detailed Approval Activity history is primarily available while a post is awaiting approval, so I'd investigate whether its audit/export capabilities meet your legal-record requirements before committing. Sprout Social Support

If client experience matters most

Ovia is interesting because it explicitly tracks every caption, crop, change, approval, approver, and version, while allowing clients to review without creating an account. Ovia

Bottom line:

• Compliance/legal + audit trail → Hootsuite
• Large agency managing many client accounts → Sprout Social
• Simple client review + strong version history → Ovia

If you tell me roughly how many clients/posts you manage and whether legal approval needs to be a formal sequential chain (e.g. Copy → Account Lead → Legal → Client), I can narrow this to the best 2–3 platforms and compare their workflows/pricing.

hootsuite.com is probably the safest starting point if legal sign-off and auditability are the priority.

sproutsocial.com is particularly attractive if you're running an agency with separate environments for lots of clients. It supports separate client accounts, roles/permissions, multi-step approval workflows, and external approvers. sproutsocial.com support.sproutsocial.com

One caveat: Sprout's detailed Approval Activity history is primarily available while a post is awaiting approval, so I'd investigate whether its audit/export capabilities meet your legal-record requirements before committing.

If client experience matters most

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

Best fit: Planable

planable.io is particularly well suited to agencies managing many clients because it combines client workspaces, approval workflows, collaboration, scheduling, and version history in the same system. Planable Planable

For your workflow, you could configure something like:

Draft → Internal review → Legal approval → Client approval → Lock approved version → Schedule/publish

The important pieces are:

• Required approvals: posts can't proceed until designated approvers sign off.
• Multi-level approvals: Enterprise supports sequential stages, which is useful for legal → client → final approval workflows. Planable
• Version history: every saved version can be reviewed, compared, and restored, giving you a record of how the post changed. Planable
• Lock after approval: prevents someone from quietly modifying the approved content afterward. Planable
• Separate client workspaces: each client can have their own content, users, permissions, and workflow. Planable
• Internal vs. client-facing feedback: your team can work privately before exposing a post to the client. Planable

Strong alternative: Sprout Social

sproutsocial.com is worth considering if you're looking for a more comprehensive enterprise social-management platform. It supports client-specific groups/permissions and multi-step approval workflows, including external stakeholders who don't necessarily need a Sprout login. Sprout Social Sprout Social

I'd favor Sprout if you also need sophisticated social listening, analytics, engagement/inbox management, and enterprise governance.

Another option: Hootsuite

hootsuite.com supports up to three approval layers, configurable approvers, and an approval history showing who sent, edited, and approved posts. It explicitly supports legal/compliance reviewers. Hootsuite

My recommendation

If the core problem is "we need to prove which version was approved by legal/client before it went live," I'd start with Planable. Its combination of version history + sequential approvals + approval locking is unusually close to the workflow you're describing.

If this is for a large agency with, say, 20–100+ clients, I can also compare Planable vs. Sprout vs. Hootsuite vs. Aprimo/Brandfolder specifically for audit trails, legal/compliance controls, permissions, SSO, and pricing.

Yes. For a multi-client agency setup where legal approval is mandatory and you need an auditable version history, I’d shortlist these:

1. Hootsuite — best for compliance-heavy operations.

It supports multi-level approval workflows, role-based permissions, approval history, editing trails, and external approvals. Hootsuite specifically supports up to three approval layers and records who edited/approved content. Hootsuite Hootsuite
hootsuite.com

2. Planable — best for agencies with lots of clients.

This is particularly attractive if your workflow is agency → internal review → legal → client → publish. It supports separate client workspaces, multi-level approvals, client-facing approval, and version history showing what changed and when. Enterprise retains version history indefinitely. Planable Planable
planable.io

3. Sprout Social — strong middle ground.

It has client-specific groups/permissions and multi-step approval workflows. Its Approval Activity records edits, comments, workflow status and approvers, while its audit trail includes events such as post creation, editing and approval. Sprout Social Support Sprout Social Sprout Social Support
sproutsocial.com

What I'd choose

If legal/compliance is the primary concern, I'd lean Hootsuite Enterprise.

If you're an agency managing many clients and want the client approval experience to be exceptionally simple, I'd lean Planable Enterprise.

The workflow I'd want the platform to enforce is:

Draft → Internal review → Legal approval → Client approval → Lock approved version → Schedule/publish → Permanent audit record

The important detail is locking/re-approval after edits. You don't want someone changing a legally approved caption afterward without triggering legal review again. Hootsuite and Planable both address this kind of approval/version-control requirement. Social Media Dashboard Planable

If you tell me roughly how many clients, users, and posts/month you have—and whether this is for a regulated industry like financial services or healthcare—I can narrow it to the best 2–3 platforms and compare their approval hierarchy, audit trail, version retention, client access, and pricing.

Yes. For that requirement, I’d look first at Planable and Sprout Social.

Best fit: Planable

planable.io is particularly well suited to an agency managing many clients because it combines:

• Separate workspaces per client, keeping brands and permissions isolated. Planable Planable
• Required approvals so a post cannot be scheduled/published until approval is obtained. Planable
• Multi-level approval workflows on Enterprise—for example: Content → Legal → Client → Final approval. Planable
• Version history, including who changed what and the ability to compare/restore earlier versions. Enterprise retains history indefinitely. Planable
• Internal discussions and notes that can remain hidden from the client until you're ready. Planable
• A centralized approval queue for people approving content across multiple client workspaces. Planable

A workflow could look like:

Writer → Account Manager → Legal → Client → Locked/Approved → Scheduled → Published

The lock-after-approval feature is particularly useful for legal compliance because you can prevent someone from quietly changing the copy/media after sign-off. Planable

Strong alternative: Sprout Social

sproutsocial.com is the better choice if you also need a more comprehensive enterprise social-management platform. Its approval workflows support multiple steps and multiple approvers, and its Approval Activity records edits, comments, workflow status, and who performed actions. Sprout Social Support It also has client-specific groups, permissions, calendars, and separate environments for agencies. Sprout Social

My recommendation

If your primary problem is "we need legally defensible approval and version control across dozens of clients," I'd choose Planable Enterprise.

If the requirement is broader—approval + publishing + social listening + analytics + large enterprise social operations—I'd evaluate Sprout Social alongside it.

One important distinction: if by "legal approval" you mean you need a formal compliance/audit trail (e.g., regulated financial, healthcare, pharmaceutical, or highly regulated advertising), I'd also evaluate dedicated compliance/workflow platforms rather than assuming a social scheduler's approval history is sufficient for your legal/audit requirements.

For a multi-client environment where posts need legal approval steps, auditability, and version history, you’ll want a social media management / content approval platform with workflow controls, not just a scheduler.

Good fits to evaluate:

For a legal review process, I’d prioritize these features:

• Approval stages: e.g., Creator → Account Manager → Brand Manager → Legal → Scheduled
• Approval locking: once legal approves, edits should force a new review cycle
• Immutable history: who changed what, when, and which version was approved
• Role permissions: legal reviewers should approve without being able to accidentally publish
• Client separation: each client needs its own workspace, assets, calendars, and approval rules
• Exportable records: useful if you need compliance evidence later

My shortlist based on your requirements:

1. Gain — strongest match if legal/compliance documentation is the priority. Gain
2. Hootsuite Enterprise — better if you’re a large organization with governance requirements. Hootsuite
3. Planable or Ovia — better if you’re primarily an agency managing many clients and want smoother client sign-off. Kontentino Ovia

A key question: are these posts mainly social media posts (LinkedIn/Instagram/etc.), or do you also need approval history for ads, PDFs, web pages, and other marketing assets? That changes the best choice.

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

Planable

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

Agorapulse

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.
