JustSignup vs Konstella for PTA sign-ups
Konstella is a private community platform for PTAs and PTOs: directory, rooms, messaging, payments and sign-ups, behind a verified-parent login. The school pays, from $424 a year on Basic to $1,274 on Platinum, plus a 3% + 20¢ fee on payments at the Basic tier (Konstella FAQ, September 2026). JustSignup does one of those jobs, the sign-up sheet, without a login or an app, for free on the first page and $79 a year for the PTA's whole calendar.
| Konstella | JustSignup | |
|---|---|---|
| What it is | A whole-school community platform: directory, groups, messaging, payments, sign-ups | A sign-up page: shifts, jobs and items, with reminders and a waitlist |
| Who can sign up | Verified parents of the school, approved by the Konstella admin or invited by code | Anyone with the link: parents, grandparents, the neighbor who helps every year |
| Accounts | Parent account and app (iPhone, Android, web) | None. Name and email |
| Chasing non-responders | One-click email to families who haven't read the sign-up | Share only the open spots; a reminder the day before to everyone who did sign up |
| Payments | Yes, through Stripe; 3% + 20¢ Konstella fee on Basic, none on Premium and Platinum | Not offered |
| Price | School pays $424, $849 or $1,274 a year; free for parents | First page free; Pro $9/mo or $79/yr for the PTA |
If your school has adopted Konstella, use its sign-ups; everyone is already there. If your PTA is choosing a tool for sign-ups alone, or you need something the whole community can use without joining anything, JustSignup is the lighter answer at a fraction of the price.
