At five staff, the cheapest booking tool is a flat plan — but a cheap per-seat one runs it close

Ask “what’s the cheapest booking tool” with one person at the desk and the answer is almost always $0 — ten of the seventeen vendors in our index publish a free tier. The question changes shape the moment you have a team. Booking software bills one of two ways: per seat (you pay for each staff member who takes appointments) or flat (one account fee, staff included up to a cap). The intuition is that per-seat pricing punishes you as you grow, so a flat plan must win at five staff. At the very bottom of the market that intuition holds — but only just, and only because one flat plan is unusually cheap. A cheap enough seat beats every other flat plan even at five.

So we fixed the workload at five staff who each need a calendar and a login, and priced the self-serve plans in our 17-vendor index that can seat all five, on both billing terms. (Two vendors — Fresha and Vagaro — publish no confirmable self-serve USD price and are quote-only, so they can’t be ranked here.)

What five seats actually costs

Vendor	Plan	Billing	5 staff/mo, billed annually	5 staff/mo, billed monthly	Notes
TidyCal	Pro	Flat	$8.25	$12	$99/yr or $12/mo; flat, not per seat; up to 25 calendar connections
Picktime	Pro	Per seat	$11.25	not recorded	$2.25/user/mo annual × 5; uncapped, no staff limit
Picktime	Starter	Per seat	$15	$20	$3/user annual or $4/user monthly × 5; uncapped
Setmore	Pro	Per seat	$25	$60	$5/user annual or $12/user monthly × 5
Acuity Scheduling	Standard	Flat	$27	$34	Up to 6 staff
Bookeo	Standard	Flat	$39.95	$39.95	No annual discount; 20 consultants; Small ($29.95) caps at 3
Doodle	Team	Per seat	$44.75	$105	$8.95/user annual or $21/user monthly × 5; 2–100 users
GlossGenius	Gold	Flat	$48	$56	Up to 9 users
Square Appointments	Plus	Flat	$49	$49	No annual rate; per location, multi-staff booking
Calendly	Standard	Per seat	$50	$60	$10/seat annual or $12/seat monthly × 5
Calendly	Teams	Per seat	$80	$100	$16/seat annual or $20/seat monthly × 5
YouCanBookMe	Team	Per seat	$81	$90	$18/member monthly × 5, less the 10% billed-yearly saving

The thesis the buyer question implies — that flat plans win at five staff — survives at the very top of the table, and nowhere else. The single cheapest plan that seats all five is TidyCal Pro at $99/yr, or $8.25/mo, a flat fee that rides the whole team on one account. The cheapest per-seat plan, Picktime Pro at $11.25/mo ($2.25/user at the annual rate, ×5), is $3 behind it and carries no staff cap at all; its sibling Picktime Starter is $15/mo for five on annual billing. Billed month to month the gap widens: TidyCal Pro is $12, while the cheapest per-seat plan that publishes a monthly rate, Picktime Starter, is $20 (Picktime Pro’s monthly-billed rate isn’t recorded). Everything after that is the real lesson: Calendly Standard lands at $50/mo for five seats ($10/seat annual, ×5), and Teams pushes that to $80 annual, $100 billed monthly. It isn’t “per-seat loses,” it’s “an expensive seat loses.” A $2.25 seat beats every flat plan but one; a $16 one doesn’t come close.

The seat price, not the billing model, is the variable

The cleanest way to read this market is to stop asking “flat or per-seat?” and ask “how cheap is the seat?” A low enough per-seat rate beats almost every flat plan; a high one loses to all of them. Picktime proves the point: at $2.25/user/mo annual its Pro plan is $11.25 for five and uncapped, so it beats every flat plan in the table except TidyCal Pro’s $8.25 — Acuity, Bookeo, GlossGenius and Square included — while still being per-seat. The flat-vs-seat framing is a red herring; the price-per-seat is most of the story.

Flat plans matter where a vendor has no cheap seat to sell. Take Bookeo, which is flat-only. Bookeo Small is $29.95/mo flat — but for 3 consultants, so it can’t actually seat five. The plan that does is Bookeo Standard at $39.95/mo, which covers 20 consultants with no per-seat charge — below Calendly Standard’s $50, but well above Picktime, TidyCal, Setmore, and Acuity.

Among the rest of the per-seat tools, the spread is wide. Setmore Pro is $5/user/mo on annual billing, so five seats is $25/mo — cheaper than Acuity, though Setmore’s free tier stops at four users, one short of our test. Doodle Team is $8.95/user/mo annual ($44.75 for five), and Calendly Standard $10/user ($50). The catch on the cheap annual rates is the monthly-billed price: Setmore Pro is $12/user/mo month-to-month, which is $60 for five — more than Acuity’s $34, Square’s $49 or GlossGenius’s $56 on the same monthly terms. Doodle Team jumps to $105 and Picktime Starter to $20. The per-seat advantage at the low end is real only if you prepay the year.

The recurring floor, with an asterisk

The lowest recurring number for five seats is TidyCal Pro at $99/yr ($8.25/mo), or $12/mo billed monthly — one account fee for five staff. The cheapest per-seat plan, Picktime Pro at $11.25/mo ($2.25/user annual), is the runner-up. Below those two, the only way to beat the paid floor is to go free: Appointlet’s Free tier seats up to 5 members (capped at 25 booked meetings/mo) and Doodle’s Free tier is unlimited users ($0, group-booking oriented) — both seat a five-person desk for nothing if their limits fit your volume.

There’s also a one-time option: TidyCal’s Agency tier is a single $79 payment (confirmed flat, unlimited team members, no recurring fee), which costs less than a single year of any subscription on this list — TidyCal Pro’s own $99/yr included — and less than seven months of Pro billed monthly. None of these — Picktime, TidyCal, Appointlet, Doodle — makes a HIPAA claim. They’re lean booking-page tools, not salon or clinic operating systems. If you need a signed BAA, only five vendors in the index publish one (Setmore, Acuity, vcita, GReminders, Vagaro), and none of them is the price floor.

What the per-seat tools are actually selling

It would be easy to read this as “the cheapest tool is the right tool,” but price isn’t the only axis. The higher numbers in the table buy capability, not just seats. Calendly Teams’ $16/seat (annual; $20 billed monthly) buys Salesforce, round-robin and lead routing; Square’s $49 flat plan is a full point-of-sale with payments and no-show fees baked in; GlossGenius Gold at $48 annual, $56 billed monthly (up to nine users) bundles its Forms & Waivers with a HIPAA-compliance option that an $8–12 booking page simply doesn’t have. (GlossGenius advertises HIPAA capability but publishes no BAA — if a signed BAA is a hard requirement, that rules it out and points you to Acuity, Setmore, vcita, GReminders, or quote-only Vagaro instead.)

So the honest answer to the per-seat-vs-flat question is “it depends on the seat price,” not “flat wins at scale.” A cheap seat like Picktime’s $2.25 or Setmore’s $5 annual beats every flat plan but TidyCal Pro even at five staff. A pricey seat like Calendly Teams’ $16 does not — there a flat plan that covers your headcount (TidyCal Pro at $99/yr, Acuity Standard at $27, or Bookeo Standard at $39.95) wins. The mistake isn’t picking per-seat; it’s not multiplying the seat price by your real headcount before you renew.

How to read this

At five staff, the cheapest plan that seats everyone is a flat one: TidyCal Pro at $99/yr ($8.25/mo), or $12 billed monthly, just ahead of the cheapest per-seat plan, Picktime Pro at $11.25/mo (annual, uncapped). Picktime Starter at $15, Setmore Pro at $25 and Acuity Standard at $27 (all annual) are the next rungs; Calendly Standard’s $50 is the price of staying on a high-priced per-seat tool past the point where it pays off. If your booking volume is light, Appointlet’s and Doodle’s free tiers seat five for $0. The rule is simple: the billing model doesn’t decide the winner on its own — the seat price and the billing term do — so multiply it out on the terms you’ll actually pay before you renew.
