The short answer
Treatwell is a booking system with a built-in marketing module. NuvenarHub is a WhatsApp + CRM + ad-attribution platform that uses Treatwell as the booking back-end. They are complementary, not competing. Most clinics that grow past a single location run both, because Treatwell handles the calendar perfectly and NuvenarHub handles everything that happens before and after the booking.

Where they overlap and where they do not
Treatwell covers the booking surface: clients find you on the Treatwell marketplace, book a slot, get reminders, leave a review. That motion works well and there is no reason to replace it.
Treatwell does not cover everything that happens around the booking:
- Lead capture from outside Treatwell: Meta Lead Ads, Instagram DM, WhatsApp click-to-chat, organic web enquiries. Treatwell does not see these; NuvenarHub captures all of them into a CRM and routes to the next available rep.
- WhatsApp as the primary channel: most UK aesthetics customers prefer WhatsApp over SMS. NuvenarHub is WhatsApp-native. Treatwell offers WhatsApp via partner integrations only.
- Ad-spend attribution: when a clinic spends £5k a month on Meta ads, the founder wants to know which campaigns produce booked revenue. NuvenarHub tracks ad to message to booking to revenue. Treatwell shows bookings but not the channel that drove them.
- Calling with AI summary: outbound and inbound calls recorded, transcribed by Whisper, summarised by Claude with sentiment and next actions. Treatwell does not have a calling stack.
- Multi-location operator view: an operator with 3 clinics on Treatwell sees three siloed marketing modules. NuvenarHub Enterprise gives one workspace per location with shared admin and consolidated reporting.
The recommended stack for a UK clinic in 2026
- Treatwell: keep it as the calendar, the booking page, and the source of truth for appointments. Use the basic plan, not the marketing-premium plan.
- NuvenarHub Pro (or Enterprise for 3+ locations): handle WhatsApp, lead capture, CRM, broadcasts, AI replies, ROAS, calling. Sync to Treatwell.
- Stripe: if you take deposits or sell packages, plug into the NuvenarHub invoicing module which is Stripe-backed.
Net cost: Treatwell base + NuvenarHub Pro. Net revenue: tracked attribution that shows which ad spend produces bookings, plus the WhatsApp channel that most customers actually use. The clinics that move to this stack typically see a 30 to 60 percent growth in recurring revenue over a 90-day window, primarily because WhatsApp follow-ups recover no-shows and bookings that Treatwell-only setups lose.
Migration plan (about 2 hours)
- Connect Treatwell to NuvenarHub via the integrations panel.
- Import the customer list from Treatwell. NuvenarHub keeps Treatwell as the source of truth and adds enrichment (lifecycle stage, lead source, custom properties).
- Wire your WhatsApp Business number into NuvenarHub.
- Connect Meta Lead Ads if you run paid acquisition.
- Set up the AI auto-reply for your top 10 question categories.
- Run the first reactivation broadcast to dormant customers (typical open rate above 70 percent on WhatsApp).
