SignUpGenius, SignUp.com, Google Forms, or a PTO platform? 2026 pricing, what the free tiers actually limit, and which one fills shifts for a parent group.
Most parent groups pick a volunteer signup tool once, in a hurry, during the first week of school, and then live with it for a decade. The choice matters less than boards think for small events and more than they think for the ones that need forty adults on a Saturday. This guide compares what each option costs in 2026 and where each one breaks.
Not here to compare? Two shortcuts:
- Want a free PTO volunteer signup tool you can post today, with no parent logins and no per seat pricing? Start there; this guide is for boards weighing tools against each other.
- Comparing whole PTO platforms rather than signup tools? The PTA software comparison covers accounting, membership, and directories alongside signups.
1. What a volunteer signup tool has to do
A volunteer signup does four things: it shows open slots with a date and a time, it lets a parent claim one in under a minute, it sends a reminder before the shift, and it tells the coordinator who is coming. Everything past those four is convenience.
The failure mode is almost never the software. It is the account wall. Every login a parent has to create between the link and the claimed slot costs you volunteers, and the loss is heaviest among the families you are trying hardest to reach: new parents, second language families, and anyone signing up from a phone in a pickup line. Ask of any tool whether a parent can claim a shift from a text message without registering.
The second question is who owns the list next year. A signup living in a departing volunteer coordinator's personal account is a list you will rebuild from scratch. Tools that allow more than one organizer without charging for the privilege are worth real money to a board that turns over every June.
Key Takeaway
Judge a signup tool on two things: how many taps stand between the link and a claimed slot, and whether next year's coordinator can get into the account. Feature lists are mostly noise.
2. Comparison at a glance
Prices below are 2026 list prices taken from each vendor's own pricing page. Nonprofit and school discounts exist at several of them and are worth asking about before you pay.
| Tool | Free tier | Paid from | Parent login? | Best for |
|---|---|---|---|---|
| SchoolRelay | Yes, full signups | $99 / yr | No | Signups that live on the public parent page |
| SignUpGenius | Yes, with ads | $107.89 / yr | No | Boards who want the format parents recognize |
| SignUp.com | Yes, 1 organizer | $99.99 / yr | No | Groups that need SMS reminders on a budget |
| Google Forms | Yes, unlimited | Free | No | One off collection where slots cannot run out |
| Konstella | No | Several hundred / yr | Yes | Schools already running the whole platform |
| Membership Toolkit | No | Several hundred / yr | Yes | Large PTOs needing signups tied to membership |
3. SignUpGenius: the one everyone already knows
SignUpGenius is the default in American schools, and that familiarity is a genuine advantage. Parents have used it for soccer snacks and class parties, so the layout needs no explanation. Slots, quantities, and date grouping all work the way a coordinator expects.
The free tier is advertising supported, and the ads are the reason most boards eventually upgrade. On a conference signup shared with four hundred families, an advertisement sitting above the slot list looks like something the PTO chose to put there. Paid plans start at $11.99 a month, or $107.89 billed annually, which removes advertising and adds custom themes, more administrators, and higher email and text limits. Gold runs $29.99 a month and Platinum $59.99 a month for larger groups.
The weakness is that a SignUpGenius link is an island. It sits in an email, and when the email scrolls away the signup is effectively gone. Boards that pair it with a permanent page parents can return to fill more shifts than boards that only send links.
4. SignUp.com: the closest direct competitor
SignUp.com (formerly VolunteerSpot) does the same job with a cleaner free tier. The Basic plan is free with unlimited participants, unlimited signups, and unlimited email, which is more generous than it first appears. The limits are structural rather than volume based: one assistant organizer, one custom question, one group page, and no SMS reminders.
Those limits map badly onto a PTO. One assistant organizer means the president cannot help the volunteer coordinator without sharing a password, which is the exact handoff problem from section one. Starter at $99.99 a year lifts the group page cap and adds unlimited SMS reminders, and SMS is the single upgrade most likely to change fill rates. There is also a Campus plan starting at $99 a year aimed at K-12 schools, worth pricing against Starter because the feature sets differ more than the price does.
Plus at $249.99 a year adds waivers and five assistant organizers. Max at $499.99 a year adds hours tracking, which matters if your district requires logged volunteer hours or your group reports them for a grant.
5. Google Forms: the free do it yourself route
Google Forms costs nothing, has no participant cap, and every board already has an account. For collecting interest, gathering allergy information, or asking who can bake, it is adequate and nobody should be talked out of it.
It fails at the one thing signup tools exist for: limited slots. Google Forms has no native way to close an option once it fills, so nine parents claim the 9am shift and nobody claims the 2pm. Add on scripts can approximate the behavior, and every one of them is a dependency on the volunteer who installed it. There are also no automatic reminders, which is a larger loss than most boards expect. Reminders, not recruiting, are what turn a claimed slot into an adult who shows up.
Use Google Forms when running out is impossible. Use something else when it is not.
6. Signups bundled inside a bigger platform
Konstella and Membership Toolkit both include volunteer signups inside a larger system that also handles directories, membership dues, and in Membership Toolkit's case accounting. Both run to several hundred dollars a year and both require parents to hold an account.
Neither is worth buying for signups alone, and buying one for that reason is the most common overspend in this category. They earn their price when a school is already committed to the platform for membership and directory work, at which point a separate signup tool is one more login and one more list to reconcile. If you are evaluating them as whole systems rather than as signup tools, the PTA software comparison is the better page, and there are dedicated writeups for Konstella and Membership Toolkit.
The account requirement deserves weight. A platform that asks every parent to register will reach the engaged third of your families well and the other two thirds barely at all. That tradeoff is defensible for a private school with a hundred families and much harder to justify for a Title I elementary with eight hundred.
7. SchoolRelay: signups attached to your public page
SchoolRelay takes the opposite position from the platforms: no parent account, ever. Volunteer signups sit on the same public page that carries your announcements, calendar, and links, so a parent who arrives to check the spirit week date sees the open shifts on the way past. Signups are part of the free tier, and the $99 a year Pro plan adds push notifications and custom branding rather than gating the signups themselves.
The tradeoff is real and worth stating. Without accounts there is no parent to parent messaging and no private directory, so a school that wants a closed community should look at Konstella instead. What you get for that is a link that works for every family on the first tap, and a page that is still there in November when the email is gone. The volunteer signup page covers how shifts, reminders, and cancellations work.
8. What the free tiers actually cost you
Every tool here has a free tier, and the free tiers are not equivalent. Three costs recur:
- Advertising. A free SignUpGenius signup carries ads that parents may reasonably read as PTO endorsements. For a conference or fundraiser signup that reaches the whole school, this is the tier's real price.
- Single organizer accounts. Free tiers that allow one administrator push boards toward shared passwords, which is how a signup list leaves with a departing volunteer. Read the officer transition guide before you set up any account in a personal name.
- No SMS. Text reminders are behind the paywall almost everywhere. If your no show rate is the problem you are trying to fix, SMS is the feature you are actually shopping for, and it is worth more than themes, custom questions, or design control.
None of that argues for paying. It argues for knowing which limit will bite first, because every board hits one of these three in the second semester.
9. How to choose in ten minutes
Answer three questions in order and the field narrows to one or two options.
- Can slots run out? If no, Google Forms is finished and free. If yes, keep going.
- Do parents already have accounts on a platform you pay for? If yes, use the signups you are already buying. Adding a second tool splits the list and doubles the reconciling.
- Is the problem recruiting or attendance? Recruiting problems are solved by putting the signup somewhere parents already go, which means a permanent page rather than an email. Attendance problems are solved by SMS reminders, which means a paid tier somewhere.
Whatever you pick, create the account under a role address such asvolunteers@yourschoolpto.org rather than a personal inbox, and add a second organizer on day one if the tier allows it. The volunteer recruitment toolkit covers the asking half of the problem, which is the half no software solves.
