Every other kind of proof is approved as a flat thing and delivered as a flat thing. A wrap is approved as a flat template and delivered on an object with curves, seams, recessed handles, a fuel flap and a rear door that opens.
That mismatch is where wrap disputes come from, and almost none of them are about whether the design was nice. They are about where the design ended up once it was on the vehicle.

The four things that go wrong
The wrong vehicle. A template for a 2019 Transit Custom is not a template for a 2023 one, and a long-wheelbase van is not the same object as the standard body. The customer says "a Transit"; the template says otherwise once the vinyl is on the floor.
Hardware in the wrong place. A door handle through a phone number, a fuel flap in a logo, a seam through a face. On the flat template, that hardware is a faint outline nobody was asked to look at.
Curvature nobody accounted for. Text that runs across a body line or a wheel arch stretches and skews in a way the flat proof does not show. Read straight-on it is fine; read from the pavement it bends.
Coverage understood differently. "Full wrap" to a customer often means the whole van including the roof and the rear doors; to a quote it might mean three sides. That is a commercial argument dressed as a design one, and it is settled by the proof or not at all.
What to confirm before you print vinyl
The exact vehicle, in writing, before design. Make, model, year, body length, roof height, and whether the rear is barn doors or a tailgate. The cheapest version of this is a photo of the actual van plus the registration, which settles all of it at once.
Show the panel lines. Proof on the template with the hardware and seams visible rather than on a clean rectangle. If the customer never sees the door handle in the proof, they have not agreed to where it lands.
Check the supplied logos at vehicle scale. A logo pulled off a website is a few hundred pixels wide and the side of a van is two and a half metres — the one problem a preview hides completely, because the file looks perfect at screen size. Check what it can print at before it goes into the layout, rather than after the customer has approved a picture of it.
Call out the compromises yourself. The seam between the door and the panel runs through the tagline here — this is how it will look. A customer who is told this before printing treats it as a design decision. A customer who discovers it at handover treats it as a defect.
Say what is and is not included. Panels wrapped, panels left in body colour, roof, rear doors, whether the wrap is cut around the glass. In the proof, not only in the quote.
Photograph the vehicle before installation day. Existing damage, prior vinyl, mismatched paint. This is not a proofing step, but it is the same instinct: write down what everybody agreed the starting point was.
Getting a sign-off that means something
Wrap work usually has two approvals, and separating them is worth the extra message:
- The template and coverage — the right vehicle, the right panels, hardware and seams in the right places.
- The artwork — the design as it will be printed on that template.
Approving the second without the first is how a beautiful design gets printed for the wrong van. When the yes comes back, make sure it names a version: "approved v2", not "looks great". Wrap jobs go through more rounds than most, and a bare "approved" three rounds in refers to whichever file the customer happens to have open.
If the approval arrives on the phone from someone standing next to the vehicle — which is normal on this work — write it back to them within the hour, naming the file and the time. There is a copy-and-paste version of that message in our artwork approval email templates.
Where a review link helps
Our own tool, so read this with that in mind.
Proofavo sends the customer one link rather than an attachment. No account, no login, and it works on the phone they are holding while standing next to the van — which is where wrap feedback actually happens.
Comments land as pins on the artwork, so "the handle is going to cut through this" is attached to the exact spot rather than described in a reply. Because zoom is on the reviewer's side, somebody can look closely at the panel gap without you exporting a detail crop for them.
The approval binds to the exact file, and a revision supersedes the previous version rather than sitting beside it in an inbox — so there is one current template and one current design, which matters on a job that goes through five rounds. Every approval produces a downloadable record naming the version and the approver, with a SHA-256 fingerprint of the file. When somebody asks why the tagline sits where it sits, that record is the answer.
Flat pricing from $29.90/month, with reviewers always free — the fleet manager, the owner and the marketing person can all look without costing you a seat.
What it does not do: it does not model curvature, generate templates or preflight the file. It is where a person agrees to a specific version, and where that agreement is kept.
