# Customer proof points expire. Track them.

*Sep 9, 2026 · svgslid.es blog*

Logos, quotes and case studies come with permission, and permission has an end date. Keep a proof library in Sheets and get warned before a quote goes stale.

## TL;DR
- Every customer logo and quote you use was approved by someone, for some use, until some date. Write all three down.
- One row per proof point: claim, customer, scope, source of approval, expiry, days left, used in.
- A Workspace Studio flow can check the sheet weekly and post what is about to expire to Chat.
- September’s new Studio steps (Move Drive file, Copy Drive file) can also move retired assets out of the way.

## The logo strip nobody re-checked

A customer agreed to a logo on the website two years ago. Their champion left. The logo is still on the homepage, in four decks and on a printed one-pager. Nobody knows whether the permission covered print.
Proof points are borrowed. Treat them like anything else with a licence: record the terms, and track the end date.

## The proof library

- **Claim:** the exact words you use. “Cut file transfer tickets by 60%.”
- **Customer** and **contact** who approved it.
- **Scope:** logo, name only, quote, case study, website, print, events. A dropdown keeps it consistent.
- **Source:** a link to the approval: an email, a signed form, a comment in a doc.
- **Expires:** the date the permission ends, or a review date if it has none. One year is a sensible default.
- **Days left:** `=IF(G2="","No date",G2-TODAY())`, with red under 30 and amber under 90.
- **Used in:** every asset that carries it.

The **Used in** column is what makes expiry cheap to handle. When a quote ends, you already know which files to open.

## Get warned before it expires

Workspace Studio builds flows from starters and steps, without code. A weekly flow with two steps is enough here:

- **Starter:** on a schedule, every Monday morning.
- **Step:** ask Gemini, with the Proof sheet as its source, to list rows with fewer than 30 days left, with the claim, customer and Used in.
- **Step:** notify the proof owner in Chat.

On September 2, Google added four new Studio steps (https://workspaceupdates.googleblog.com/2026/09/automate-drive-gmail-and-google-chat-actions-with-new-steps-in-Workspace-Studio.html): Move Drive file, Copy Drive file, Send a Chat reply and Reply to email. Move Drive file lets the same flow move an expired logo file from your shared assets folder to a Retired folder, so nobody drops it into a new deck.
One constraint to plan around: Google’s getting-started guide (https://support.google.com/workspace-studio/answer/16444479) says flows fail on files in shared drives or shared folders, and on spreadsheets that use IMPORTRANGE. Keep the sheet the flow reads private to the flow owner.

## On the page

- **Logos as vectors.** A customer logo pasted as a PNG goes soft in print and can’t be recoloured for a one-colour strip. Add the logo to Google Slides as an SVG (https://svgslid.es/guides/svg-logos-icons-google-slides) and recolour it (https://svgslid.es/guides/recolor-svg-in-google-slides) to match the strip.
- **Tag each logo** in its alt text title with the proof row key, such as `proof:acme-logo`. Then a search, by hand or by script, finds every use.
- **Quotes keep their attribution** exactly as approved: name, title, company.

## What we have tested

- **Checked in Sheets:** the Days left formula.
- **Not yet built by us:** the Studio flow above. Starter and step names follow Google’s help pages; your Studio may label them slightly differently.
