Sign Proof Approval Checklist: Get Sign-Off Right the First Time
A clear proof approval process for sign shops and their clients: what every proof should show, what the client must check, how to limit revisions, and how to stop costly changes after production starts.
Tool for this: SignAcctPro — Sign shop software: estimating with supplier prices, true-scale mockups and drawings, proofs, jobs and invoices.
The most expensive words in a sign shop are "that's not what I approved." A misspelled name on a channel letter set, a wrong color on a wrapped van or a size the landlord rejects all cost real material and labor to fix. A clear proof approval process protects both sides: the client gets exactly what they expect, and the shop gets a signed record of what was agreed.
What every sign proof should show
A proof is not just a picture. Before it goes to the client, check that it includes:
- Exact wording and spelling, including names, phone numbers, addresses and web addresses.
- Overall dimensions and key measurements (letter height, panel size), with the unit clearly stated.
- Colors named by vinyl code, paint code or Pantone, not just "blue."
- Materials and finish: acrylic, aluminum, ACM, vinyl type, matte or gloss.
- Illumination (if any): front-lit, back-lit (halo), or non-lit.
- Mounting method and, ideally, a mockup on a photo of the actual wall or vehicle.
- Quantity, especially for multi-sign or ADA packages.
- Job reference number, proof version number and date.
What the client must check
Send a short checklist with every proof and ask the client to confirm each line:
- All text is spelled correctly, including names and numbers.
- Size fits the space and meets landlord or HOA rules.
- Colors match their brand.
- Logo is the current version.
- Mounting location is correct.
- They understand that screen colors can differ slightly from the finished sign.
Asking the client to check line by line works far better than "please approve."
Limit revisions, in writing
Endless revisions are where most proof disputes begin. Put the rules in your quote before work starts:
- Revisions included: for example, two rounds of changes per proof.
- Extra revisions: charged at a stated rate.
- New design vs revision: a new layout, a new concept or new content is a new design, not a revision.
- Complete brief first: ask for all text, logos and measurements up front. Most "revisions" are really missing information.
Clients rarely argue with rules they agreed to at the start. They often argue with rules that appear at the end.
Get a real sign-off
A "looks good" text message is not an approval. Ask for one of these:
- A signature on the proof (paper or e-signature).
- An approval button or reply that records the name, date and proof version.
Write on the proof itself: "I approve this proof as shown. Changes after approval may result in extra charges and a new delivery date."
After approval: protect production
- Lock the version. Production uses only the approved version number.
- Changes after approval are a change order with a new price and date, approved again in writing.
- Keep the record. Store every proof version and every approval with the job. If a dispute happens months later, the file answers it.
