For PTA chairs, boosters, room parents, coordinators

Describe the event. It does the arithmetic.

One sentence in. Back comes how much you need, what that comes in at the store, and who is bringing what — so you are not the one doing the sums at 9pm.

Real package sizes

It knows what a supermarket shelf actually holds.

Shredded cheese comes in 8 oz, 6 oz and 32 oz. Plates come 30 to a pack. Those sizes were read off real shelves, not guessed — so the list tells you what to put in the cart, not just what you are short of.

Where the numbers come from

A guess wears a dotted underline until you confirm it. We would rather show you which numbers to check than pretend all of them are facts.

What it will not do

It does not guess what anything costs. It is good at how much food a hundred people eat and bad at what your store charges this week, so prices are yours to fill in. The budget total is a total of what you typed.

One event, or a whole season

Nine games, or twenty classroom parties. One link.

A season of games, or a row for every teacher's party, on one sheet with one link. Paste the list straight out of the coach's email or your Google Sheet and it reads the dates, times, names and places back to you, saying what it had to assume. Set what each one needs once, then change any one without touching the rest.

Things and people

Some things need bringing. Some jobs need somebody.

Your sheet holds both, and counts them separately — so you can see the food is covered and nobody has signed up to serve it.

A sign-up sheet

One list. Everything on it is a slot.

Counted in people and hours, never in bags.

Once it is over

Next year's plan already knows you ran out of cheese.

Six taps afterwards: how it went, and for each item whether there was too much, about right, or not enough. Duplicate the event next year and the corrected plan comes with it, with no claims attached. Nothing else on this page compounds; this does.

The volunteer's side

What she gets is a link.

Text it or post it. She opens it on her phone, sees what is still missing with real amounts on it, and claims one with a name and an email. No account, no password, no app. Reminders, cancellation links and thank-yous send themselves.

Her page carries your organization's name and the sheet, and nothing else. No advertising on a volunteer's page, ever.

And the rest of the job

What else it does.

Reminders that send themselves

Emails at the times you choose, from a week out to the morning of. Text reminders are an optional extra for an event.

Instructions for the day

Write “drop everything at the front office” once, and it goes in the day-before and morning-of reminders.

Message everyone who signed up

One note to everyone on the sheet, from you, and their replies come back to you.

You hear before it goes wrong

A note before the day with what is still open, and an email the moment somebody cancels.

A link that looks right on Facebook

Post your sign-up link and the preview shows your event, its date, and what still needs somebody.

Check people in on the day

A phone list of who is coming and what each person is bringing. Tick them off at the door, and see what never turned up.

A waitlist when it fills

Parents who find the sheet full can leave an email, and hear once if a spot opens.

Questions for volunteers

Ask for a child’s name and teacher, or allergies. Only the people running the event see the answers.

One page for your whole group

Everything your PTA needs help with right now, on one link for the newsletter.

In Spanish, checked by you

Families can read the sign-up sheet and get their emails in Spanish. It is translated for you, and you read and change every line before anyone sees it.

Switching takes one paste

Coming from SignUpGenius? Paste your old sign-up and see it rebuilt here, with the quantities worked out, before you make an account.

The paper sheet counts too

Print a “How it went” sheet, mark it with a pen after the event, and take a photo of it. The review fills itself in, and anything unclear is left for you rather than guessed.

A thank-you that shows what you learned

The day after, every volunteer gets a thank-you with your photos and, if you choose, a recap: what ran short, what was too much, and what changes next time. No names on it.

Volunteers keep track too

The sign-up email carries a calendar entry for the day, and if a volunteer makes an account, their slots are waiting in it.

How it fits your group

Nobody has to learn software.

Your organization

Events belong to the PTA or the booster club, not to whoever created them, so next year's chair inherits the lot.

Your committee

Admins manage the roster; members plan and publish events.

Everyone else

Volunteers claim from the link and get the reminders you choose — a week out, three days, the day before, the morning of.

Describe your next event. Correct what's wrong. Send the link.

What it costs

Free to use, and free of advertising. Volunteers never pay and never make an account — they claim a slot from a link with a name and an email.

It is not free to operate, though. So once an event is over, we ask you once whether it was worth contributing to, and take no for an answer. The rest of the questions.
