Content approval software for agencies: 5 tools compared
Short answer: Content approval software exists to stop drafts getting approved or rejected over email, where feedback gets lost in a thread and nobody can tell which version a client actually signed off on. As of October 2026, Planable's Basic plan runs $33 a workspace a month for 60 posts, Gain's Starter plan is $99 a month for 3 team members, Pallyy's Pro plan is $25 a month for a single social set, Filestage's Starter plan is $199 a month for unlimited projects, and Ziflow's Standard plan is $199 a month billed annually. Planable and Pallyy lean toward social content specifically, Gain is built around agency-client approval relationships, and Filestage and Ziflow handle broader creative files like video and PDFs. None of the five give a client anything beyond the approval step itself.
You want clients to approve content in one place with a clear trail, not scattered across email replies and Slack messages that are easy to lose.

What a content approval tool actually needs to do
Content approval sounds like a simple feature, but a tool that handles it well needs a few specific things working together.
- Version clarity: When a client says "approved," the tool needs to make it unambiguous exactly which version that applies to, especially after a few rounds of revisions.
- Comments tied to the content: Feedback attached to a specific line, frame or image, not a general comment that requires guessing what it refers to. See shared creative boards for client feedback.
- A record of who approved what, and when: Useful for billing disputes and for proving a client signed off before something went live.
- Enough workspace separation: One client shouldn't be able to see another client's drafts or comments.
The best content approval tools, compared
Planable
Planable, a social media content planning and approval tool built around a visual feed and calendar view, prices its Basic plan at $33 a workspace a month for 60 posts and 4 social pages, and Pro at $49 a month for 150 posts, 10 social pages and required-approval workflows (Basic only supports optional approval, not a hard gate). Pricing is per workspace, which usually means per client, so an agency running several clients needs to multiply this out, and a Social Inbox add-on for managing comments costs $7.50 a workspace a month extra. If Planable is not the one, Planable alternatives compares five others.
- Best for: Agencies specifically managing social content (more in social media agency software) who want a visual calendar clients can browse, not just a list of posts to approve.
Gain
Gain, an approval workflow tool built specifically around agency-client content sign-off, prices its Starter plan at $99 a month for 3 team members and 6 workspaces, and its Agency plan at $199 a month for 6 team members and 12 workspaces, adding white-label branding and white-label PDF reports clients can download. Every tier includes unlimited reviewers, which matters since the number of client stakeholders who need to weigh in is usually the variable agencies underestimate.
- Best for: Agencies that want the approval tool itself to look and feel white-labeled to the client, not just branded on the surface.
Pallyy
Pallyy, a social media scheduling tool with built-in approval workflows, treats each client as one "social set" and prices its Pro plan at $25 a month for a single set with 1 user, and its Agency plan at $99 a month for 10 sets and 3 users, with additional sets or users at $10 a month each. Approval workflows are available from the Pro tier up, which makes this one of the cheaper entry points on this list for a single-client use case.
- Best for: A smaller agency or freelancer running a handful of social clients who wants scheduling and approval in the same cheap tool.
Filestage
Filestage, a review and approval platform built for creative files including video, PDFs and design assets rather than social posts specifically, has a genuinely usable free tier for 1 active project and 5 new files a month, then jumps to $199 a month for its Starter plan covering unlimited active projects and files. Its Business plan at $329 a month adds "review agents" for automated compliance checks and more reviewer groups.
- Best for: Agencies approving video, design files or long documents, not just social posts, where frame-by-frame or page-by-page commenting matters.
Ziflow
Ziflow, a proofing and approval tool supporting over 1,200 file types, offers a genuinely free tier for 2 users with unlimited proofs and reviewers, then Standard at $199 a month (annual) for 15 free users and 2 workflow stages, and Pro at $329 a month for 20 free users and 3 workflow stages plus integrations with Asana and monday.com. The multi-stage workflow support, routing a proof through more than one approval step in sequence, is a genuine differentiator from the social-first tools on this list.
- Best for: Agencies with a formal multi-step internal review before anything goes to the client, not just a single client approval gate.

A worked example: 5 social clients, 20 posts each a month
Say you run 5 social clients, each needing roughly 20 posts approved a month, 100 posts total across the agency. On Planable, that's comfortably inside the Pro plan's 150-post ceiling if you run all 5 clients in one shared workspace, at $49 a month, or you could split clients into separate workspaces for cleaner access control, which would push you toward $33 times 5 on the Basic plan instead, closer to $165 a month. On Pallyy, 5 social sets land you on the Agency plan at $99 a month regardless of post volume, since Pallyy doesn't cap posts the way Planable does. Gain's Agency plan at $199 a month covers up to 12 workspaces, more headroom than this scenario needs, but its white-label PDF reporting may be worth the extra cost if clients specifically want a downloadable sign-off record. The right pick here depends less on the raw math and more on whether you want per-client workspace separation (Planable Basic) or a flatter per-set cost that doesn't change with volume (Pallyy).
When approvals belong inside a full client portal
All five tools above do one job, getting content approved, and do it well. None of them hold the brief that content was built against, the invoice tied to that work, or the campaign results it fed into. For a client who only interacts with your agency around content sign-off, that separation is fine. For a client who's also checking results, approving invoices and reading status updates, having approvals live in a different tool from everything else means another login and another place for them to miss a notification. Some agencies solve this by routing approvals through a client portal that holds the brief, the approval and the results together in one branded view, rather than running a dedicated approval tool as a separate client touchpoint.
How I'd approach this
If content approval is the only client-facing friction you're trying to fix, pick based on content type: Pallyy or Planable for straightforward social content on a budget, Gain if you want the tool itself to feel white-labeled, and Filestage or Ziflow once you're approving video or design files with a multi-step internal review before the client ever sees it (see these Filestage and Ziflow alternatives). Where I'd step in is if approvals are just one piece of a bigger pattern, where clients are also chasing status, invoices and results across several disconnected tools, in which case a single portal covering all of it usually serves the client better than five point solutions stitched together.
Questions people ask
What's the cheapest content approval tool for agencies?
Pallyy's Pro plan at $25 a month for a single client is the cheapest entry point on this list, though it's built specifically around social content rather than broader creative files.
Which content approval tool supports multi-stage review?
Ziflow supports multi-stage workflows from its Standard plan ($199 a month, annual), routing a proof through sequential approval steps. Filestage adds similar multi-group review at its Business tier ($329 a month).
Can clients approve content from their phone?
All five tools work in a mobile browser, though the experience varies. Planable and Pallyy, built around social content, tend to feel more natural on mobile than Filestage or Ziflow, which are built more around desktop review of larger files.
Is content approval software the same as a client portal?
No. These tools handle one specific step, getting a draft approved, and don't hold a client's brief, invoices or campaign results. A client portal covers that broader view, with approvals often as one piece of it.
Do any of these tools have a free tier?
Filestage and Ziflow both offer genuinely usable free tiers for small-scale testing, 1 project with 5 files a month on Filestage, and 2 users with unlimited proofs on Ziflow. Planable, Gain and Pallyy's free or trial options are more limited.
Roughly what does a custom approval workflow cost?
As a broad reference, fixes and finishes start at around $1,500, and new builds start higher, always a fixed price agreed in writing before I start, never an hourly rate. My AI app cost guide explains what actually drives a quote up or down.
Is my agency too small for this?
No. Most of the owners I work with have no tech team at all, that is the whole point. If the smarter move is a cheap software subscription instead of custom software, I will tell you that on the first call, even though it means I do not get paid.
