The best client approval software for an agency depends on three things: how deep your proofing needs to be, how your clients prefer to review, and how your pricing needs to scale. Here's a shortlist of six products (ApproveLite, GoVisually, Filestage, ReviewStudio, Ziflow, and PageProof), compared on the dimensions that decide the purchase. Pricing is as listed on each vendor's pricing page in October 2026; verify current numbers before you buy.
The shortlist at a glance
| Tool | Best for | Pricing model | Starting price | Client/reviewer access | Proofing depth |

| GoVisually | Design proofing for creative teams | Per user | $16/user/mo (Lite) | Invited reviewers | Moderate: design annotations, video/GIF on Pro |
| Filestage | Structured, multi-step proofing | Flat team pricing | Free plan; $199/mo (Starter) | Link + email, no account | Deep: compare versions, workflows |

ApproveLite
ApproveLite is the simplest option on this list, built for agencies that want work, feedback, versions, and final approval together, without per-seat pricing or forcing clients through account setup. Clients review through a shareable link with no account and approve or request changes. Feedback can be left in context on images, videos, PDFs, and documents, with unlimited versions and an approval history that stays with each request. Requests tie to clients, workspaces, and projects, carry scheduled dates, and appear on a content calendar clients can view read-only.
Best reason to choose it: one clean workflow across file types, flat team pricing, and no client onboarding. The workflow it's built for: a clear approve-or-request-changes loop across file types, with feedback in context and approval tied to the exact version.
GoVisually
GoVisually is an online proofing tool focused on design and artwork review, priced per user. Lite is $16/user/month (for 1–5 users, 15 active projects, 15 external reviewers, no video or GIF support). Pro is $33/user/month with a 3-user minimum, adding 250 projects, unlimited external reviewers, video and GIF support, custom branding, and Zapier, Slack, and Adobe integrations. Annual billing saves about 20%, and there's no free plan.
Best reason to choose it: a focused, design-first proofing workspace with strong annotation and branding controls. Main tradeoff: per-user pricing multiplies as your team and reviewers grow, and video support requires the Pro tier.
Filestage
Filestage is a structured proofing platform with a real free plan (1 active project, 10 team members, unlimited reviewers). Starter is $199/month with 10 team members, unlimited projects and files, due dates and reminders, compare versions, and custom branding. Business is $329/month, adding review agents, automations, workflow integrations, and extra review decisions. Reviewers don't need an account; they enter an email. Filestage is GDPR-compliant and ISO 27001-certified, hosted in Germany.
Best reason to choose it: structured multi-step review workflows with a genuine free tier and flat team pricing. Main tradeoff: the jump from free to $199/month is steep for a small team, and the automation depth is more than a simple approve-or-request-changes loop needs.
ReviewStudio
ReviewStudio is per-user proofing with a free plan. Free covers unlimited users but only 3 active reviews. Pro is $12/user/month billed annually (about $15 monthly) with 10 active reviews per user and 25 GB per user; Advanced is $20/user/month billed annually (about $25 monthly) with a 5-user minimum, adding workflows, client and project teams, comment privacy, and API access. It supports all file formats, versioning, and compare and present modes.
Best reason to choose it: affordable per-user proofing with a free tier and solid compare/present tooling. Main tradeoff: per-user costs climb with headcount, and the free plan's 3-review limit is tight.
Ziflow
Ziflow is the workflow-heavy option. The free plan covers 2 users with unlimited proofs and reviewers and pixel-level version comparison. Standard is $199/month billed annually with 15 users and 2 workflow stages; Pro is $329/month billed annually with 20 users, 3 stages, minor versions, and Slack, Teams, Asana, monday.com, and storage integrations. Reviewers never need a license. Enterprise adds SSO, audit logs, e-signatures, and unlimited stages.
Best reason to choose it: multi-stage workflow automation and enterprise controls for high-volume, regulated content. Main tradeoff: the depth and price are overkill for a simple review loop, and lower tiers cap workflow stages.
PageProof
PageProof is premium flat-rate proofing with no per-seat charges and unlimited reviewers, proofs, and storage. Team is $249/month; Team Plus is $499/month (adding SSO, scheduled proofs, and advanced branding); Enterprise is custom-priced and adds compliance, data residency, and digital signing. It supports the broadest file range (static, video, audio, websites, email, 3D, and prototypes), plus side-by-side comparison and automated workflows.
Best reason to choose it: enterprise-grade proofing and compliance with flat, all-inclusive pricing. Main tradeoff: the starting price is the highest on this list, and the compliance and AI tooling is far beyond a small agency's needs.
When to choose which
- ApproveLite: you want a simpler approval workflow, no per-seat pricing, and clients who review without accounts.
- GoVisually: design-focused proofing with per-user pricing is acceptable and you need video/GIF review on the Pro tier.
- Filestage: you want structured review stages with a free tier, and $199/month flat is in budget.
- ReviewStudio: you want per-user pricing with a free plan and compare/present modes.
- Ziflow: you need multi-stage workflows, automation, and enterprise controls.
- PageProof: you need the deepest proofing and compliance, and a flat premium price is fine.
How to decide
- Write down your review loop. If it's send → review → revise → approve, you don't need workflow stages or automation.
- Count your seats honestly. Multiply per-user prices by everyone who touches a proof, including occasional reviewers.
- Check client friction. A login requirement is the single biggest cause of delayed approvals.
- Verify current pricing. Every figure here is from October 2026 and will change.
Frequently asked questions
Which is cheapest for a small agency?
ApproveLite at $15/month flat, or ReviewStudio's free plan if you can live with 3 active reviews. GoVisually's Lite at $16/user is also low for a one- or two-person shop. Run the numbers at your own headcount.
Do reviewers count as paid seats?
It varies. ApproveLite, Filestage, Ziflow, and PageProof don't charge for external reviewers; GoVisually caps reviewers on Lite and makes them unlimited on Pro; ReviewStudio uses unlimited guests. Check each vendor's current seat definition.
Which tool is best for video approval?
Ziflow and PageProof have the deepest video and rich-media review; Filestage and ReviewStudio handle video well too. ApproveLite supports video review through the same request-and-version workflow as every other file type, with feedback left as comments on the work and approval recorded against the exact version.
