How does the no-monthly-fee model work for booking software?

Instead of charging a monthly subscription, GrabMySlot charges 3% plus Stripe's standard payment processing fee on each deposit collected. If you collect a $50 deposit, GrabMySlot takes $1.50. If you collect no deposits in a month, your cost is zero. The fee only applies when you're actively using the deposit collection feature.

At what volume does a 3% fee become more expensive than a $39/month subscription?

At 3% per deposit, you'd need to collect $1,300 per month in total deposit value to equal a $39/month subscription. That's 26 deposits of $50 each, or 13 deposits of $100 each, or 8 deposits of $150 each. Most service businesses at typical solo volumes stay well below that threshold.

Does GrabMySlot charge anything other than the 3% fee?

No. The 3% covers GrabMySlot's platform fee plus Stripe payment processing. There's no setup fee, no monthly minimum, no per-seat charge (and no feature gating, all features are available from the first booking.

Why would a software company charge per transaction instead of monthly?

The per-transaction model aligns the software company's revenue with the provider's activity. When the provider collects more deposits, GrabMySlot earns more. When the provider has a slow month or goes on vacation, GrabMySlot earns nothing. This is the opposite of a subscription model, where the company earns the same regardless of whether you're using the software.

Booking Software With No Monthly Fee: How the 3% Model Works

Most booking software charges a monthly fee whether you use it or not. Acuity Scheduling at $34/month. Jobber at $39 to $119/month. HouseCall Pro at $59 to $299/month. These are predictable costs with predictable feature sets.

GrabMySlot works differently: no monthly fee, 3% of each deposit collected. This is a better model for a specific type of service provider. It's worth understanding when it's cheaper, when it's not, and what the math actually looks like at different business volumes.

How the 3% model works

Every time a customer pays a deposit through GrabMySlot, GrabMySlot takes 3% of that deposit amount. The 3% covers GrabMySlot's platform fee and Stripe's payment processing combined. Nothing else is charged. No monthly fee. No setup fee. No per-user charge. No feature tiers that require upgrading to access deposits.

A concrete example: a plumber collects a $75 deposit on each service call. GrabMySlot takes $2.25. The plumber receives $72.75. At 15 service calls per month, the plumber collects $1,125 in deposits and pays GrabMySlot $33.75. That's the entire software cost for the month.

In January, when the plumber takes two weeks off and collects five deposits instead of fifteen: $11.25 in fees. In a week with zero bookings due to illness: $0. The cost moves with the business, not against it.

When the 3% model costs less than a subscription

The breakeven point against a $39/month subscription is $1,300 in monthly deposit volume. Here's how that plays out at different deposit amounts and booking volumes:

Deposit per booking	Monthly bookings for breakeven vs. $39/mo	Monthly bookings for breakeven vs. $59/mo
$25	52 bookings	79 bookings
$50	26 bookings	39 bookings
$75	17 bookings	26 bookings
$100	13 bookings	20 bookings
$150	9 bookings	13 bookings

A solo plumber doing 10 service calls per month with a $75 deposit pays $22.50 in GrabMySlot fees. That's $16.50 less than Jobber's Core plan (which doesn't even include deposits) and $36.50 less than Jobber's Connect plan. A personal trainer doing 20 sessions per month with a $40 deposit per new client pays $24, less than Acuity's Growing plan at $34/month.

When the 3% model costs more

High-volume businesses collecting large deposits will eventually pay more in percentage fees than a flat subscription would cost. A roofing contractor collecting a $500 deposit on every estimate visit across 50 estimates per month is collecting $25,000 in deposits and paying $750 to GrabMySlot. A flat Jobber subscription is a fraction of that.

The inflection point varies by deposit size and volume, but the pattern is consistent: the 3% model is better for lower-volume businesses and for businesses with variable monthly activity. Fixed subscriptions are better for high-volume operations where monthly booking counts are predictably high and deposit amounts are large.

What you get with no monthly fee

The no-monthly-fee structure means slow months don't create financial pressure. A seasonal landscaper whose business drops 80% in winter pays nearly nothing during those months rather than $39 to $59/month for software that's largely idle. A trades provider who takes a three-week vacation pays zero during those weeks.

There are no feature tiers to navigate. Every GrabMySlot feature, deposit collection, Google and Outlook calendar sync, automated reminders (team round-robin scheduling) is available from the first booking. There's no "you need to upgrade to access deposits" gatekeeping.

The honest comparison with Jobber

Jobber Core is $39/month. It does not include deposit collection. Jobber Connect is $119/month and does. For a solo contractor who specifically needs deposit collection, the relevant comparison is GrabMySlot's 3% versus Jobber's $119/month.

A contractor collecting $50 deposits on 15 service calls per month ($750 total deposit volume) pays GrabMySlot $22.50. The same contractor on Jobber Connect pays $119. The difference is $96.50 per month, or $1,158 per year. GrabMySlot does not include Jobber's invoicing, CRM, or GPS dispatch. For contractors who need those features, Jobber Connect is worth the price. For contractors who don't, the math is clear.

GrabMySlot is free to start. No monthly fee. You pay 3% plus Stripe's standard payment processing fee only when you collect a deposit. Set up your booking page at grabmyslot.com.
