Send the link. Clients review. Approved.

Client approval software lets an agency send a piece of content to a client, capture the client's approval decision, and keep the decision connected to the submitted version and date. The job is replacing scattered email-thread approvals with one review workflow the client can open from their inbox.

No. Writerflow uses magic links: the client clicks a link in their email, sees the document in their browser, leaves comments, and approves or requests changes. No signup, no password, no app download. Reviewer access is free on every plan. Reviewer friction is worth checking before you roll out any tool, because it varies more than the category's marketing suggests: some issue a browser review link that asks only for a name and email, some allow comment-only public links but need an invitation before a formal decision can be recorded, and some require a full account.

Eligible Google Workspace accounts include formal Approvals that can keep a decision connected to an approved version and expose approval details. Writerflow is a fit when an agency also needs the brief, brand voice, revisions, client decision, and approved handoff connected around the written deliverable while keeping its existing drafting stack.

Writerflow sends automatic reminders on a schedule you set and shows which review is still waiting. No response remains pending until the reviewer or another authorized human records an explicit decision.

Writerflow is purpose-built for written client content — blog posts, articles, newsletters, briefs, white papers, ad copy, scripts, press releases, and long-form marketing content. For visual proofing of design files or video assets, tools like Filestage or Ziflow are a better fit. The two categories use the word "approval" but the workflows, review surfaces, and tooling are different.

Filestage is well-built for visual proofing (design, video, banner ads). Writerflow is built for written content. On reviewer access the two are closer than they look: Filestage documents a browser review link that does not require an account, asking a reviewer for a name and email before feedback. Compare them on what written review actually needs — inline comments on specific sentences, a diff of what changed in the copy between drafts, and the decision staying attached to the version it was given on.

Three uses. (1) Dispute resolution — when a client says "I never approved that," you can export a timestamped record of who approved what version on what date, with their IP and email captured. (2) Client-side documentation — for agencies serving regulated-industry clients (financial services, healthcare, legal) where the client needs to show a record of content sign-off. (3) Internal accountability — when a piece ships wrong, you can show whether it was an internal review failure or a client-side approval that came in late. Writerflow itself is not currently SOC2-certified — agencies whose own organization requires enterprise compliance gates (SOC2 Type II, SSO/SCIM, EU data residency) should reach out before signing.

Plans start free, then $49/month for Studio (1 seat; $99 for 3, $149 for 5) with unlimited clients and unlimited documents.
