A brief is checked against the client’s monthly creative cap before it reaches design.
A Google Sheets add-on totals the creatives a brief asks for, compares them with the client’s monthly cap and logs the submission. Over-cap work goes to the account manager instead of straight to design.

The business problem
Each client buys a set number of creatives a month: statics, carousels, GIFs or videos, landing pages. A brief lists what the team wants made. Checking it means adding up the brief and everything the client’s other briefs have already used that month. It was a manual sum, done brief by brief.
What changed
Yash built Scope Check as a Google Sheets add-on. The project manager runs it from the sheet’s Extensions menu or a side panel. It reads the request table, looks up the client’s caps in a master workbook, subtracts what other briefs have used and shows the result under the table. Submitting logs one row per creative type to a central ledger. If the brief is over cap, a Yes/No prompt sends it to the account manager as pending approval.
Before & after
| Area | Before | After |
|---|---|---|
| Cap check | A manual sum, brief by brief | One click, against the client’s monthly caps |
| Over-cap briefs | Relied on someone spotting them | Flagged, then pending account manager approval |
| Record of requests | Spread across individual briefs | One ledger row per brief and creative type |
| Sign-in | Each brief carried its own script and an authorisation prompt | One private add-on, installed once for the whole domain |
The business value
The check covers five creative types and counts only live work: rejected and superseded ledger rows are ignored, so a resubmitted brief does not count against itself. The add-on went live for the whole company on 5 November 2026. No time saving is claimed, because nobody tracked how long manual checks took.
The value is control more than time: over-cap work is seen before design starts, and every submission leaves a record. Try your own volumes in the savings calculator.
Why the system is dependable
The logic is tested away from the sheet. One suite has 21 assertions and an adversarial suite has 50 checks: 47 pass and three document known limits, such as a time-zone edge case on ledger dates. The add-on asks for four permissions, each with a stated reason. Before the switch, the old script was backed up.
A closer look at the build

Could this work for your team?
If a monthly allowance lives in people’s heads and a spreadsheet, a small check at the point of submission can keep it honest without a new system.
