$320 a month is $3,840 a year before you've added anything
Walla's entry tier is $320/month per location. That's a defensible price for a studio doing $40,000 a month across several rooms and staff — it's a hard price for a 60-member yoga studio where the software bill would be eating a visible share of monthly revenue. And $320 is the floor, not the average: the Pro tier that carries the full marketing suite, branded app, and two-way texting is $599/month per location.

$69/month, flat, with every feature included. $828 a year. No tier above it to graduate onto and no feature held back to justify one.
