Can Google Forms limit responses natively?

No. Google Forms has no built-in response cap or scheduled close. You can only toggle 'Accepting responses' manually. FormGuard adds the missing controls: a total response limit, per-choice quotas, and scheduled close/reopen, enforced automatically.

What happens when the response limit is reached?

FormGuard stops accepting responses and shows late respondents a clear custom message instead of letting them submit into an overfilled list. Per-choice quotas work the same way: when one workshop option fills up, only that option closes — the rest of the form stays open.

Can a form close and reopen on a schedule?

Yes. Set a close time (for example Friday 5 PM) and an optional reopen time. The form enforces the schedule on its own, so you never have to remember to flip the switch — or apologize for forgetting.

Response limits & scheduled close

Stop babysitting your Google Form's response count

Google Forms has no native response cap. FormGuard adds what teachers actually need: a total response limit, per-choice quotas so one workshop doesn't overbook, and scheduled close/reopen for deadlines. Set it once — the form enforces it, and late respondents get a clear message instead of a silent overfill.

Install FormGuard Close after N responses

How it actually works: Google Forms offers no built-in cap — the limit is enforced by FormGuard's triggers, which watch submissions and flip the form closed at exactly the number you set. No script to maintain, no manual toggle to remember.

Quick fit check

Need	Fit
Cap total signups (e.g. 100 seats, then stop)	Good fit: set the number, the form closes itself.
Limit seats per choice (workshop A: 20, workshop B: 15)	Good fit: per-choice quotas; a full option closes while others stay open.
Close at a deadline, reopen later	Good fit: scheduled close/reopen runs on its own.
Waitlists after the cap	Partial: late respondents see your custom full message; pair with a second form for waitlist capture.
Complex approval chains after signup	Not a FormGuard use case — see FormFlow.

Manual monitoring vs limiter add-ons vs FormGuard

Every approach enforces the cap somehow. The difference is who remembers, and what the respondent sees.

Decision point	Manual toggle	Basic limiter add-ons	FormGuard
Enforcing the cap	You watch the response count and flip "Accepting responses" off by hand — at midnight, on weekends, during class.	Usually a single total cap.	Total response limit plus per-choice quotas, enforced automatically at exactly the number you set.
Deadlines	Set an alarm. Hope you hear it.	Varies; scheduling is often absent.	Scheduled close and reopen — the form opens Monday 8 AM and closes Friday 5 PM on its own.
Late respondents	They submit into an overfilled list and you email apologies.	Depends on the add-on.	They see your custom "we're full" message immediately. No silent overfill.
Per-option sellouts	Not possible natively.	Rarely supported.	One full workshop option closes; the rest of the form keeps accepting signups.

Set it up in five minutes

Install FormGuard and open it on your form.
Set the total response limit (e.g. 100).
Optional: add per-choice quotas on the questions with limited seats.
Optional: set a close time — and a reopen time if signups run in windows.
Write the custom message late respondents will see.
Test with the form open: submit past the cap and confirm it closes with your message.

Why teachers stop doing this by hand

The classic failure is the overnight overfill: signups close "at 100" in the announcement, but nobody is awake at 2 AM to flip the toggle, and by morning there are 134 responses for 100 seats. The second classic is the popular workshop: one session fills in an hour while others sit half-empty, and the form has no way to say "this option is full, pick another." A cap that only works when someone is watching is not a cap. FormGuard watches so you don't have to.
