Features

NextAvailableSlot is online scheduling software for service businesses. Put a booking calendar on the website you already have, or use the hosted page we give you — then let availability, reminders and records take care of themselves.

A booking calendar you can embed on your own website

Paste a snippet into any site you can add HTML to — Squarespace, WordPress, Webflow or a hand-written page — and visitors book without leaving it. There is no redirect to a third-party domain and nothing for them to sign up for first.

  • One script tag; three install shapes depending on whether you want a single event type, a whole business, or an inline calendar
  • Inherits your page rather than dropping a branded box into it
  • Bookings land on the same calendar as everything else and sync out to Google or Outlook

A branded booking page, if you do not have a website

Every business gets a hosted page at its own address, with its own name, description, imagery and terminology. It works as your whole web presence or as the link in a bio, an email signature or an invoice.

  • Custom URL slug, so the address reads as yours
  • Business-model presets (education, fitness, consulting, healthcare) relabel the interface to match how you talk about your work
  • Three separate booking addresses — the business page, an event type's own page, and a professional's availability page

Availability rules that survive real life

Set the hours you repeat every week, then override them for the weeks you do not. Buffers, notice periods and daily caps stop the calendar from selling you a day you cannot work.

  • Recurring weekly hours, plus one-off date exceptions
  • Seasonal rules with a start and end date, so a schedule change can be set up in advance instead of remembered on the day
  • Buffers between bookings, minimum notice, how far ahead people can book, and a cap per day

Two-way Google Calendar and Microsoft Outlook sync

Connect the calendar you already live in. Bookings appear there, and anything already there blocks the slot here, so you cannot be double-booked by someone who never saw your personal calendar.

  • Two-way: bookings push out, existing events block availability coming back
  • Google Meet and Zoom links generated automatically on the booking
  • Control what a booking is called in your own calendar, for shared or work calendars

Scheduling for a team, not just for you

Each professional keeps their own hours, their own calendar connection and their own booking page, while the business keeps one view of all of it.

  • Invite professionals or approve the ones who request to join
  • Assign clients to specific professionals
  • Availability can span more than one business, and a booking in one blocks the slot in all of them

Session packs, plans and payouts

Sell a block of sessions rather than one appointment at a time. Each booking spends a credit, expiry is yours to set, and what each professional is owed is calculated as the work happens.

  • Plans that grant a pack of credits, with your own pricing and expiry
  • Per-client payout rates, in more than one currency if you work across borders
  • Payments, receipts, refunds and a downloadable payroll statement

Confirmations, reminders and cancellation windows

The back-and-forth that scheduling usually generates happens without you. Clients confirm, reschedule and cancel inside the rules you set.

  • Automatic confirmation and reminder emails
  • Cancellation windows, so a late cancellation is handled by policy rather than by argument
  • Rescheduling that respects the same availability rules as a new booking

A record of what actually happened

Attendance, no-shows, retention and an activity trail of every change, so the schedule is also the reporting.

  • Mark what was delivered; no-shows and cancellations are counted separately
  • Retention reporting per client
  • An activity trail showing who changed what, and when
