Everything in the free version
- Time-slot booking. Customers pick a date, then choose from the open times you offer, based on your hours and slot length.
- Google Calendar sync. DrezSync connects to your own Google Calendar, so every booking lives in the calendar you already use.
- Auto-block booked times. Anything already on your calendar is hidden from the form, so the same slot is never offered twice.
- One booking field per form. Drop a booking into any Gravity Form with a single field.
- Custom accent color. Set the color of the selected time button to match your brand.
What DrezSync Pro adds
- Date-range booking for rentals. Let customers book a range of days, check-in to check-out, for rentals, stays, or equipment hire.
- Slot capacity for group bookings. Allow more than one booking in the same time slot, up to a limit you set, for classes, tours, or tastings.
- Multiple booking fields per form. Put more than one booking on a single form, each tied to its own calendar.
- Calendar chosen by a form answer. Route each booking to a different Google Calendar based on what the customer picks, such as a location, staff member, or service. DrezSync books the matching calendar.
- Overlap protection across fields. When a form has more than one booking, DrezSync stops the same person from choosing times that clash.
- Custom event titles and customer invites. Choose what each calendar event is called, and automatically send the customer a Google Calendar invite.
- Priority support. Direct email support is included with your Pro subscription.

Frequently Asked Questions
Getting started
Do I need Gravity Forms?
Yes. DrezSync is an add-on for Gravity Forms, so you need it installed, active, and licensed. DrezSync adds one field to your forms. It does not replace your form plugin, and it does not work on its own.
Do I need a Google Workspace account, or will a normal Gmail work?
A normal Google account is fine. DrezSync connects to whichever Google Calendar you point it at, personal or Workspace. You do not need a paid Google plan.
How long does setup take?
The Google connection takes about ten minutes and you only do it once. It is the longest part, because Google asks you to create a project and authorise your own account. After that, adding booking to a form is a single field and takes a minute.
What if I would rather not do the Google setup myself?
We offer a done-for-you setup for a flat $149. We connect Google Calendar to your site and the deliverable is simply the plugin showing Connected.
Do I need to be technical?
No, but the Google connection involves following a step-by-step guide through Google’s own console, which is fiddlier than most plugin setups. It is copy and paste rather than code. If that is not how you want to spend an evening, the done-for-you setup exists for exactly that reason.
How it works
Where does my booking data go? Can you see it?
No. The connection is strictly between your website and your own Google account. Nothing is sent to Ally Drez, and DrezSync does not track your visitors or add analytics. Your bookings are saved as normal Gravity Forms entries on your site, and your events go on your own calendar.
What stops two people booking the same time?
DrezSync reads your Google Calendar live, so a time that already has an event never appears on the form. It also re-checks availability at the moment someone submits, so the slot cannot be taken in the gap between choosing and submitting.
Does it work with my theme or page builder?
DrezSync adds a field to a Gravity Form, so wherever your form works, the booking field works. There is no separate booking page or template to fit into your design. You also set the accent colour of the selected time, so it matches your brand rather than ours.
Can I use more than one calendar?
Yes, and this is in the free version. Each booking field connects to one Google Calendar, and you can put as many booking fields on a form as you need, each with its own calendar and its own hours. Pro adds two things on top: overlap protection across those fields, so the same person cannot be booked twice at once, and dynamic routing, where a single field picks its calendar from another answer on the form, such as a Location dropdown.
What does the calendar event look like?
Every booking is written to your calendar with the details the customer entered in the event description. On Pro you can set your own event title using merge tags, for example “Consultation with Jane Smith”, and have Google send the customer their own calendar invite.
Free and Pro
What is actually free?
A complete booking tool. Time-slot booking, Google Calendar sync, automatic blocking of taken times, as many booking fields per form as you need each with its own calendar, and a custom accent colour. The free version is not a trial or a crippled demo. It is a working booking plugin, and for a lot of businesses it is all they will ever need.
What does Pro add?
Growth features, not core function: date-range booking for rentals with check-in and check-out times, slot capacity for group bookings, overlap protection across booking fields, calendar routing by another field, custom event titles, automatic customer invites, and priority support.
What happens if my Pro subscription lapses?
You keep everything. The Pro features you are already using keep working, and your forms and bookings stay intact. A lapsed subscription only stops future updates and priority support. You bought it, you keep it. Renewing restores updates and support.
Can I move my licence to another site?
Yes. Deactivate it on the old site from the DrezSync Account screen, then activate it on the new one. Deactivating does not touch your connection, forms, or bookings on the old site, it just reverts that site to the free behavior.
Will upgrading break what I have set up?
No. Your Google connection, your booking fields, and every booking carry straight across. Pro installs alongside the free version and takes over, and your existing forms simply gain the Pro settings at their defaults. There is nothing to reconfigure.
What DrezSync does not do
We would rather tell you now than have you find out after buying.
Can customers cancel or reschedule their own booking?
No. There is no self-service cancellation or reschedule link. You cancel and move bookings yourself, by deleting or dragging the event in Google Calendar, and the times reopen automatically. If customer self-service is essential to you, DrezSync is not the right fit.
Can I set a minimum notice, so nobody books the next hour?
Not currently. DrezSync offers every open slot that has not already passed, so someone could book a time ten minutes from now. There is no lead-time or minimum-notice setting.
Can I add buffer time between appointments?
Not currently. Slots run back to back within the hours you set. If you need a gap between bookings, the practical workaround is a longer slot length that includes your buffer.
How far ahead can people book?
There is no limit. Any future date on an open day will offer times. There is no setting to cap how far out the calendar goes.
Can I take payments or a deposit at the time of booking?
Not through DrezSync. Payments are Gravity Forms’ job, through its own payment add-ons such as Stripe. The DrezSync booking field sits on your form like any other field, so a form can collect both, but the payment side is configured in Gravity Forms rather than in DrezSync.
Does it send reminder emails?
Not on its own, and it is worth being precise about what sends what.
Gravity Forms sends your form’s confirmation email, the immediate “we have your booking” message. That is Gravity Forms’ job and DrezSync does not touch it.
DrezSync Pro adds one setting on the booking field, Invite the customer, which is off by default. Switch it on and the customer is added as a guest on the Google Calendar event, and Google emails them a genuine calendar invite. The appointment then sits in their own calendar, so they get whatever reminder their calendar is set to give them, usually a notification the day before and again shortly beforehand. That reminder comes from Google and the customer controls it, not you. It uses the email address from your form, so the form needs an email field for the invite to have anywhere to go.
What DrezSync does not have is a reminder scheduler of its own. There is no “email them 24 hours before” setting, no SMS, and no follow-up after the appointment. If you need reminders on your own schedule and in your own words, that is a job for Gravity Forms notifications with a scheduling add-on, or your CRM.
Support
What support comes with the free version?
The free version is supported through our documentation, which covers setup and the common questions. We are a small team, and we keep the plugin genuinely free by putting our time into clear guides instead of one-to-one support.
How do I get a person?
Pro includes priority email support. Outside that, we offer a done-for-you setup of the Google connection at a flat $149, one-off troubleshooting at a flat $95 per issue, and quotes for larger projects.
What does paid support cover?
Setting up and troubleshooting the Google connection, configuring the booking field and its rules, and diagnosing how DrezSync behaves on your site.
It does not cover your hosting, your theme, other plugins, Google account administration, or custom development, though we can quote those separately.
