You do agency-level work.
You’re doing it with WeTransfer.

The work is professional. The delivery process isn’t. Every project means the same friction — and clients sense it.

“Is this the final version?”

You sent v3 in an email. Then v4 in a follow-up. Then v4b with the fixed logo in a third thread. Now the client isn’t sure which one they actually approved — and neither are you.

Secure preview link with version history. Client approves v4b. That’s what goes live. Nothing else.

Dropbox, Drive, WeTransfer — three folders later.

Every client gets a slightly different setup. One prefers Drive, one uses Dropbox, one wants files via email. You spend time managing file logistics instead of building creatives.

One workspace per client in advox. Same structure every time. You control the environment.

“I never approved that version.”

Something went live that the client doesn’t recognize. They’re sure they signed off on a different version. You have no record. The conversation goes sideways fast.

Audit trail: version number, timestamp, who approved, when. 30 seconds to resolve any dispute.

You look smaller than you are.

Agencies send clients to structured review portals. You send a Dropbox link and a WhatsApp message. The work is equally good. The process signals otherwise to the client.

Clients approve directly in a clean interface — no account needed.

Send a link.
Get a sign-off.
Keep the proof.

Generate a secure preview link for any creative — with the real HTML5 file, not a screenshot. Your client clicks Approve or leaves a comment directly on the version. You get a locked, timestamped sign-off you can point to forever.

No client account needed — just a link they click
Shows the actual HTML5 creative, not a static image
Approval is locked to that exact version number — no ambiguity
Comments thread directly on the creative, on the version
Full audit trail: who approved, which version, when
Optional password protection for sensitive work

The practical benefit: when a client says “that’s not what I approved,” you open the audit log. Version 3, approved by [client name], 14 March, 11:24am. The conversation ends there. You don’t lose the revision round.

One workspace
per client.
Zero overlap.

Every client gets their own isolated space in advox — their campaigns, their assets, their history. Nothing bleeds between projects. And every file you upload is automatically versioned. No naming conventions, no manual tracking.

Separate workspace per client — they only ever see their own work
Every upload creates a new version automatically
Full history preserved — nothing gets overwritten
Version comparison — show clients exactly what changed
New workspace in under 2 minutes

One client, five projects, two years of history. Everything is still there, in the right workspace, with the right version trail. You can find any deliverable from any project in 30 seconds — even if the client comes back 18 months later.

Before & after

The same project. A very different experience.

WITHOUT ADVOX

Send v3 via WeTransfer with a long explanatory email
Client replies on WhatsApp with feedback — "use green, not blue"
Upload v4 to Dropbox, share link again, hope they find it
Client responds "looks good!" in an email — not a formal sign-off
Three months later: "I never approved that version"
No record, no timestamp, no proof — you eat the revision
1–2h per project on logistics, zero protection if it goes wrong

WITH ADVOX

Upload v3 → generate secure preview link → paste in one message
Client leaves comment directly on the creative in the preview
Upload v4 → new version in same link — client clicks Approve
Sign-off is locked: v4, client name, timestamp
Three months later: open audit log, 30 seconds to close the conversation
You have proof. The client doesn't have an argument.
Delivery in one link · Approval on record · No disputes

Built for how
freelancers actually work.

advox is not a tool you’ll grow into. From day one, Lite gives you what you need to run projects professionally.

Secure preview links

Share a link to the real HTML5 creative. No screenshot, no video recording. Optional password protection for sensitive client work. The client sees exactly what will run.

Complete version history

Every upload creates a new version. Every version is preserved. You can go back to any point in a project’s history — even if a client wants something “like the v2 we had”.

Comments on the creative

Clients leave feedback directly on the version they’re reviewing — not in a separate email thread. You always know exactly which version a comment refers to.

Production Plan

List every deliverable for a project — formats, sizes, placements — in a structured table. Link each row to the actual asset. Always know what’s built, what’s approved, what’s missing.

Campaign statistics

Engagement reports that show clients how their ad actually performed included in every plan.

Ready in 2 minutes

No demo needed. Self-signup via Stripe. Create your first workspace, upload a creative, send the preview link — all before your next client call. Cancel anytime.

Lite covers everything a solo freelancer needs for professional client delivery.

Straight answers.

Do my clients need to create an advox account?

No. Clients receive a link. They click it, see the creative, and click Approve or leave a comment — that's it. No signup, no password, no app to install. You can optionally add password protection to the link if the work is sensitive.

Can i run multiple clients on Lite?

Lite includes 1 workspace and 1 active campaign per month. If you work with multiple clients simultaneously, you'd either use a single workspace for all, or upgrade to Grow which gives you 3 workspaces and 3 active campaigns. For most freelancers doing sequential project work, Lite is enough.

What file types does advox support?

HTML5 creatives are the primary format — advox shows clients the actual interactive creative in the preview, not a screenshot. Images (JPG, PNG, GIF), videos, audio spots and other campaign assets are also supported for storage and versioning.

What if a client tries to dispute an approved version?

Open the audit trail for that creative. It shows the exact version number, the approver's name, and the timestamp of the sign-off. The approval is locked — it cannot be changed retroactively. That record is your protection.

Can I offer Ad Streaming to clients as a freelancer?

Yes. On Lite, you get 5,000 streaming impressions per month and can offer your clients live creative updates without re-booking. This is especially useful if you manage campaigns directly with publishers — the tag is permanent, and you control what creative runs via advox.

Is there a free trial?

There's no time-limited trial, but at €3/month you can start with Lite, run your next real project through it, and cancel anytime if it's not for you. No long-term commitment, no annual contract — it's month-to-month with immediate cancellation.

Professional delivery.
From €3/month.
