Square for Spas: Honest Review vs SupaDay (2026)

Spas run on appointments, not walk-ins. Every session blocks a treatment room and a therapist for an hour or more. The software has to handle commissions accurately, track every change, and help the spa attract new clients. Square's scheduling is solid — but commission tracking, audit trails, review management, and a real website are all missing or gated behind higher plans.

For spas with complex commission structures and a team that cares about accurate payroll, those gaps show up every week.

Feature comparison

What a spa actually pays

Solo therapist

Square Free: $0/month — booking, reminders, POS. No confirmations, no commissions, no audit trail. SupaDay Grow: $14/month — booking, confirmations, SMS (500/mo), commissions, POS, audit trail.

Square Free is free — but no commission tracking and no booking confirmations.

SupaDay is $14/month with booking confirmations, commissions, and SMS included.

4-therapist spa

Square Plus: $49/month per location — multi-staff, waitlist, SMS (500/mo), deposits, commissions. No audit trail. Square Premium: $149/month per location — adds room and equipment booking. No audit trail. SupaDay Grow: 4 x $14 = $56/month — commissions, POS, SMS, walk-in turn tracking, QR check-in, audit trail.

A 4-therapist spa needs commissions, which Square Plus covers at $49/month. SupaDay Grow is $56/month and adds a full audit trail of every booking change, plus a turn tracker and QR check-in for day spas that take walk-ins. A spa with 3 therapists pays $42/month on SupaDay — less than Square Plus.

8-therapist spa

Square Plus: $49/month per location — same price for 4 or 40 therapists, commissions included. SupaDay Grow: $99/month cap — up to 10 staff. SupaDay Business: $149/month cap — unlimited staff, website builder, reviews, multi-location.

Square's flat per-location price is hard to beat for a big team at one location. What SupaDay adds for a larger spa is an audit trail, walk-in turn tracking, and on Business, review management and a real website. No Square plan has those.

Where SupaDay wins

Commission tracking from $14 per therapist

Spas have some of the most complex commission structures in the industry. A massage therapist earns one rate on a Swedish massage, a different rate on deep tissue, and a third on a hot stone upgrade because the spa provides the equipment. An esthetician earns differently on facials vs. body wraps vs. microdermabrasion. Every service type has its own split.

SupaDay's commission tracking calculates automatically through the free POS at checkout. Therapist finishes a session, the system applies the right rate based on who performed the service and what service it was. Pull the report at end of week, run payroll — no manual reconciliation.

Square starts commission tracking on Plus at $49/month per location. On Square Free, every commission has to be calculated by hand. SupaDay charges per therapist, so a solo therapist pays $14, two pay $28 and three pay $42 — all with commissions included.

Audit trail

Every appointment change logged — who modified it, when, what changed. The audit trail tracks cancellations and shows exactly what happened with any booking. If a client says they cancelled in time but there's no record, the log shows the truth. Square users have been requesting this feature on community forums — it doesn't exist on any Square plan.

A real website for spa discovery

SupaDay includes an SEO-optimized website builder on Business at $22/user/month. A first-time spa client isn't just looking for availability — they're researching the experience, the environment, the treatment menu. Square's booking page shows your services and open slots. It doesn't tell a spa's story or help you rank when someone searches "spa near me" on Google.

Review management

SupaDay includes review management on Business. Square has no built-in review tools. Spa clients research before they book — a $120 massage from a new provider gets vetted online first. Managing that reputation should be built into the software.

Walk-in turn tracking for day spas

Not every spa runs purely on bookings. Day spas, hotel spas, and resort locations get same-day walk-ins looking for a quick facial or last-minute massage. When two therapists are available, someone has to decide who takes the next client. SupaDay's turn tracker handles rotation automatically — a 30-minute express facial counts as a half turn, a 90-minute session counts as a full turn.

Square has no walk-in management on any plan.

A marketplace to bring in new clients — no per-booking cut

SupaDay is launching a client marketplace — a searchable directory where clients find spas near them and book directly. Discovery matters more for spas than most service businesses: a new client looking for a massage therapist searches online before asking around.

The key difference from Fresha: SupaDay's marketplace has no per-booking fee. Fresha takes 20% on the first appointment for every new marketplace client — on a $120 massage, that's $24 before the spa sees a dollar. On a $200 couples package, that's $40. SupaDay's marketplace is included in your subscription. No cut per client, regardless of how many new bookings come through.

Square has no marketplace.

Where Square wins

Free plan for solo therapists starting out

$0/month for a solo massage therapist or esthetician who just needs a booking page and card reader. No other competitor offers a free tier. If you're starting your practice, have no team, and want the simplest setup possible, Square Free gets you running.

The limits matter: no booking confirmations, no commissions, no audit trail. You'll outgrow it quickly — but as a starting point, the price is unbeatable.

The Square ecosystem

For spas already using Square POS, Square Payroll, or Square Marketing, Appointments keeps everything in one place. Commission tracking on Plus and Premium feeds directly into Square Payroll. Marketing campaigns pull from your client list. One dashboard, one login.

That integration is genuine and hard to replicate with separate tools.

Waitlist

Square Plus and Premium include a waitlist — clients can sign up when popular slots are full and get notified when a cancellation opens. SupaDay doesn't have a waitlist yet. For a busy spa where Saturday morning appointments fill up weeks in advance, that's a useful feature.

Per-location pricing for large teams

Square charges per location, not per therapist. For a spa with 4 or more therapists at one location, Square Plus at $49/month covers unlimited staff, commissions included — less than SupaDay Grow at that size.

Where they match up

Both handle core scheduling:

• Online booking — clients pick their therapist, choose their service, book 24/7
• Calendar management — color-coded by therapist, day/week/month views
• Client profiles — service history, notes, preferences, allergy flags
• Staff scheduling — shifts, time off, availability
• Recurring appointments — regulars on a consistent schedule

Who should pick which?

SupaDay makes more sense if:

• You have 1–3 therapists and want commission tracking for less than $49/month
• You want booking confirmations and 500 texts a month for $14, not $49 per location
• You need an audit trail of every appointment change
• You want a real SEO-optimized website for spa discovery
• You want review management included
• You want a marketplace to bring in new clients without paying per booking (coming soon)

Square makes more sense if:

• You're a solo therapist just starting out and want free booking software
• Your spa is already in the Square ecosystem (POS, Payroll, Marketing)
• You have 4 or more therapists at one location (Plus is $49/month for unlimited staff, commissions included)
• A waitlist feature matters for your fully-booked popular slots

The bottom line

Square starts commission tracking on Plus at $49/month per location, and there's no audit trail on any Square plan. For a spa where every therapist runs different rates across multiple service types, manually reconciling commissions is a weekly problem. SupaDay Grow at $14/user/month includes automatic commissions through free POS, walk-in turn tracking for day spas, SMS reminders, and an audit trail — capped at $99 for up to 10 therapists. A spa with up to 3 therapists pays less than Square Plus, and every spa gets the audit trail and walk-in tools Square doesn't have. And SupaDay is launching a client marketplace — a way to bring in new clients across the city with no per-booking cut, unlike Fresha's 20% on first appointments. Deposit collection is coming soon to SupaDay as well. If you're a solo therapist just starting out, Square Free is a reasonable place to begin. If you have a team and want commissions, an audit trail and walk-in tools in one place, SupaDay is the stronger fit. See how SupaDay works for spas →.
