Keep the tools that work. Fix the handoffs that don't.
You should not have to replace tools that already work. This is a compatibility reference for the Booking-to-Review System and the Booking-First Website + System, not a separate offer. Compatibility reference; no partnership or certification is implied. Final qualification happens in the written scope.
step 1
Working tool
The tool you already run: booking, payments, CRM, or messaging.
step 2
Required capability
The booking, deposit, reminder, or review handoff the loop needs from it.
step 3
Compatibility status
One of four: Common candidate, Compatible, Needs review, Not compatible.
step 4
Written scope
Qualification is confirmed once access and setup are checked in scope.
Compatibility by use case.
Each tool below has its own page covering who it is built for, where it sits in the loop, what can be assessed or configured, and the limits worth knowing. Being listed here means we have written up compatibility. It does not mean an official partnership, native support, certification, or identical functionality across plans and regions.
Appointment and practice operations
Client records, intake, and appointments in one clinical or practice system. The follow-up stages usually live outside it.
- SimplePractice compatibility · Clinical practice management for behavioral health. Tight HIPAA surface.
Wellness and personal services
Personal-service and studio booking, often with a marketplace listing alongside your own booking page.
- Mindbody compatibility · Fitness, wellness, and beauty booking with a large marketplace footprint.
- Booksy compatibility · Booking and marketplace for barbers and salons. Marketplace surface plus owned booking.
Field service operations
Dispatch, technician scheduling, and job history. Request capture and post-job follow-up are the usual manual gaps.
- ServiceTitan compatibility · Enterprise field-services platform. Powerful, opinionated, and expensive to change.
- FieldEdge compatibility · Field-services platform for HVAC and plumbing shops with dispatch depth.
Scheduling and communications infrastructure
The scheduling and message-delivery layer sitting under the loop rather than a stage of it.
- Calendly compatibility · A scheduling candidate for a narrow calendar and service setup; current fit is confirmed in the written scope.
- Postmark compatibility · Transactional email with domain authentication wired for the sending domain.
If your tool is not listed, or you are not sure which of these your flow actually depends on, start with the Loop Audit. It is $495 and takes about five business days to read booking, deposits, reminders, reviews, and rebooking on the tools you already run.
- Choose booking software by business model · which tool assumptions match how you actually take work.
- What booking software should handle · where the tool's job ends and a connected workflow starts.

Two kinds of uncertainty.
Being absent from this list is a compatibility question, not a verdict. Which path fits depends on what you are actually unsure about.
technical uncertainty
You do not know what your flow does today.
Bookings, deposits, reminders, follow-up, and reviews are spread across tools and nobody has read the whole path end to end. The Loop Audit reads it and says whether a flagship system qualifies.

The unclear part is ownership, policy, or adoption.
Nobody owns the follow-up, the policy is unwritten, or the team will not use what gets installed. That is an operating-model question, and it belongs with Ray Williams Consulting before any system goes in.

Start with a Loop AuditWhat a tool has to do to qualify.
- Deposits
- The booking tool can require a deposit at the time of booking.
- Reminders
- Native SMS and email inside the tool, or a Twilio path where compatibility is confirmed in scope.
- Reviews
- A direct route to Google Business Profile, not a walled marketplace.
- Owner access
- You own every account. No agency-locked seats. No reseller dependencies.
Named out loud so nobody wastes time.
Custom in-house booking
A booking tool your prior developer built. We do not install on it.
What to do: Not compatible as built. A compatible booking tool, confirmed during scope, is the prerequisite. If you are weighing whether to move, that is an operating decision Ray Williams Consulting can talk through.
PayPal as the only payments option
PayPal alone does not cover deposit-required booking; processor compatibility is confirmed during scope.
What to do: Add Stripe or Square. PayPal can stay as a secondary option.
