Booking Systems for Service Businesses: Dubsado vs Calendly vs Custom Compared

If you run a service business — coach, consultant, photographer, therapist, wedding supplier — the right booking system is worth thousands a year in time and lost leads. Here's the honest comparison.

Calendly — best for simple "book a call"

• **Cost:** Free to £16/month
• **Best for:** Free discovery calls, sales calls, anyone who just needs a slot picked
• **Limitations:** No invoicing, no contracts, no proposals, no workflows. It's a scheduler, not a CRM.

Acuity Scheduling — best for paid sessions

• **Cost:** £12–£40/month
• **Best for:** Therapists, coaches, fitness — anyone selling individual paid sessions
• **Strengths:** Take payment at booking, packages, gift certificates, intake forms
• **Limitations:** Weak contracts, no proposal workflow, dated UI

Dubsado — best for full client workflows

• **Cost:** £30/month (£200/year)
• **Best for:** Photographers, wedding suppliers, designers, consultants — anyone with a full enquiry → proposal → contract → invoice → project flow
• **Strengths:** Genuine end-to-end CRM, beautiful client portal, automated workflows, branded everything, contracts + invoicing built-in
• **Limitations:** Steep learning curve (this is where I help — most clients save 20+ hours setting it up properly)

Custom-built booking system

• **Cost:** £4k–£15k one-off
• **Best for:** Multi-staff businesses, complex availability rules, integrations with bespoke systems, anyone whose business *is* the booking flow (e.g. a marketplace)
• **Strengths:** Exactly what you need, no monthly SaaS bill, scales infinitely
• **Limitations:** Upfront cost and you own the maintenance (or pay someone to)

My recommendation flow

• Just need calls in your diary → **Calendly**
• Paid 1:1 sessions only → **Acuity**
• Full client journey with proposals/contracts/invoices → **Dubsado** (and get help setting it up)
• Bespoke, multi-staff, or marketplace → **Custom build**

The wrong system costs you more in lost time than the right one ever costs in subscriptions. Pick on workflow fit, not price.
