What is Gravity Forms Booking?
Gravity Booking turns a Gravity Forms form into a full WordPress appointment booking system. The customer picks a service, staff member, location, date, and time slot, all inside the form.
It’s built by arguably the top WordPress development agency, WPExperts, and ships as a free WordPress.org plugin with a paid Pro tier layered on top. The free version covers basic service and availability setup.
Gravity Booking Pro adds staff, locations, calendar sync, and exports.
What it includes:
- Native Gravity Forms fields for service, staff, location, and time slot, not a bridge field
- Staff-level calendars and working hours
- A customer dashboard shortcode
- Google Calendar two-way sync and Outlook 365 integration (Pro)
- A dedicated mobile app for managing bookings on the go
- Free version on WordPress.org, Pro tiers starting at $79/year
What’s listed but not shipped: iCal, Google Meet, and Zoom are all marked “Coming Soon” on the pricing page as of this writing.
What is Simply Schedule Appointments?
Simply Schedule Appointments (SSA) is a standalone WordPress booking plugin built by NSquared. Its Gravity Forms integration adds a single Appointment field to your form.
The form collects the data. SSA owns the scheduling logic, the calendar, the notifications, everything.
It launched on WordPress.org in 2018 and has 60,000+ active installs today, with a 5.0-star rating across 154 reviews (152 five-star, the rest four and three-star, zero one- or two-star). That’s an unusually clean review record for a plugin this size.
What it includes:
- A genuine free Basic tier: setup wizard, unlimited appointment types, blackout dates, WordPress user integration
- Three booking flow layouts (Expanded, Express, First Available) and a WCAG-AA accessible widget with a built-in contrast checker
- The Gravity Forms integration, but only on Plus tier and above; the free tier doesn’t include it
- Team and resource booking, but only on the top Business tier
Be clear-eyed about the gate structure. Google Calendar sync and Zoom/Meet live on Plus. Payments and SMS reminders don’t show up until Professional.
Multi-staff scheduling is Business-only, at an introductory $399/year. A lot of buyers assume Plus gets them everything. It doesn’t.
One more thing worth flagging honestly: SSA’s early-2026 changelog shows two unauthenticated SQL injection patches and a stored XSS fix, all reported through Patchstack and fixed within days.
That’s normal for an actively maintained plugin under responsible disclosure. It’s still worth knowing before you install.
Gravity Forms Booking vs Simply Schedule Appointments: Booking Addon vs Standalone Scheduler
Gravity Booking extends Gravity Forms. Simply Schedule Appointments connects to it. That single architectural fact drives everything else.
| Element | Gravity Booking | Simply Schedule Appointments |
| What it is | Gravity Forms addon | Standalone scheduler with a Gravity Forms field |
| Where booking logic lives | Inside Gravity Forms | Inside Simply Schedule Appointment |
| Booking fields | Multiple native fields (service, staff, location, slot) | One Appointment field |
| Data model | Services, staff, locations, customers | Appointment types, team members, resources |
| Front end | The Gravity Forms form itself | SSA’s booking widget, embedded in the form |
| Requires a second admin area | No | Yes |
| Gravity Forms tier required for integration | Any | Plus edition or higher |
With SSA, you run two systems and keep them in sync. With Gravity Booking, the booking data and the form entry are the same record.
The trade-off cuts the other way too. A standalone scheduler survives if you ever drop Gravity Forms. A Gravity Forms addon doesn’t. If you’re not fully committed to Gravity Forms long-term, that’s a real consideration.

Gravity Forms Booking vs Simply Schedule Appointments For Staff, Services, And Locations
🡪 Gravity Forms Booking models a service business directly. You build services, group them into categories, assign staff with their own hours and time zones, and tie staff to specific locations.
🡪 Simply Schedule Appointments models appointment types instead, and only its top Business tier adds team members and resources.
- Staff in Gravity Booking get their own slot durations, their own working hours, and a personal login dashboard.
- Location filtering means a three-branch clinic only shows customers the slots that actually apply to the branch they picked.
That’s a meaningfully different setup from Simply Schedule Appointment’s model, where “resources” means rooms and equipment, not branches with their own staff rosters.
If your business has physical locations with different staff at each, that distinction matters.
Case Scenario
A clinic with three branches, nine practitioners, and twelve services. Gravity Booking handles this as a native data model: service, category, staff, location, all connected.
On Simply Schedule Appointment, you’d need the Business tier ($399/yr intro, $499/yr renewal) just to get team scheduling. And you’d still be approximating locations through resources rather than modeling them directly.
Where Simply Schedule Appointments Is The Better Pick
Don’t hedge here. Some use cases are clearly SSA’s:
- Solo consultants and coaches who want a Calendly-style flow
- Anyone who needs Zoom or Google Meet links generated automatically, today, not on a roadmap
- Businesses that need SMS reminders via Twilio right now
- Group and class bookings
- Teams with accessibility requirements, thanks to the WCAG-AA widget
- Anyone who wants a plugin with an eight-year track record and a five-star public review history before they commit budget
Where Gravity Booking Is The Better Pick
- Multi-staff, multi-location service businesses, once you’re comfortable being an early adopter
- Anyone who wants booking data living inside Gravity Forms entries, not a separate system
- Agencies running several client sites, thanks to multi-site licensing
- Buyers who want a lifetime license instead of rising annual renewals
- Teams that manage appointments from a phone
- Sites already deep in the Gravity Forms ecosystem who don’t want a second admin area
Gravity Forms Booking vs Simply Schedule Appointments Pricing
The headline prices look close. The real gap shows up at the feature you actually need.
| Feature | Gravity Booking | Simply Schedule Appointments |
| Entry paid tier | $79/yr (Basic) | $99/yr intro, $129/yr renewal (Plus) |
| Gravity Forms integration included at | $79/yr (native, no gate) | $99/yr intro (Plus, gated) |
| Cheapest tier with multi-staff | $79/yr | $399/yr intro, $499/yr renewal (Business) |
| Cheapest tier with true multi-location | $129/yr (Business tier) | Not available as a location entity at any tier |
| Payments included at | $79/yr | $199/yr intro, $249/yr renewal (Professional) |
| Sites per licence | 1, 3, 10, or 1,000 | 1 |
| Lifetime option | Yes | No, annual only, renews at full price |
| Money-back guarantee | 14 days | 30 days |
Run the three-year math for a five-staff, two-location business.
🡪 On Gravity Booking, that’s the $129/yr Business tier, roughly $387 over three years, or a one-time lifetime fee if you want to skip renewals entirely.
🡪 On Simply Schedule Appointments, multi-staff support alone requires Business at $399 year one and $499 every year after, putting you near $1,400 over three years, before you’ve added payments or SMS.
That gap is the number that should drive your decision if staff count is your binding constraint.
Can you switch from Simply Schedule Appointments to Gravity Booking?
Yes. Here’s the short version:
- Rebuild your SSA appointment types as Gravity Booking services
- Recreate team members as staff profiles with their own hours
- Re-point your existing Gravity Forms form to Gravity Booking’s native fields instead of the SSA Appointment field
- Export your existing appointments to CSV and import them into Gravity Booking
It’s not instant, but it’s not a rebuild from scratch either.
Verdict on Gravity Forms Booking vs Simply Schedule Appointments
If you’re a solo operator or small team with one location, and you want Zoom, SMS, and payments working today from a plugin with a proven track record, Simply Schedule Appointments is the safer buy.
If you run a multi-staff, multi-location operation and want that structure built into Gravity Forms itself, without paying $499 a year just to unlock staff scheduling, Gravity Booking is the better architectural fit.
Try the free tier first, on a low-stakes site, before you commit to a paid Business license.
