Advanced Booking Engine
Let clients book a real slot, in their own time zone, with a deposit

The problem
Scheduling costs more than the meeting
Several emails to fix one time, repeated for every prospect, every week — and the slot you offered was taken by the time they replied.
Back-and-forth over times
Proposing and re-proposing slots turns a two-minute decision into a two-day thread.
Double bookings and no buffers
A calendar that is not the source of truth eventually books two things into the same hour.
No commitment at booking
Without a deposit, a confirmed slot is only as reliable as the client’s memory.
The solution
Availability that is already true
The booking page reflects your live calendar, your service durations and your buffers — and takes payment at the moment of booking.
- Custom appointment types with their own durations and buffers
- Two-way calendar sync with Google, Outlook and iCloud
- Time-zone intelligence so clients always see their own local times
- Deposits collected through integrated payment processing
- Instant confirmation, with the pipeline updated automatically
Feature details
What booking actually gives you
The specific capabilities behind booking in InvoiceSpider.
Custom appointment types
A site survey, a discovery call and an install visit are not the same length. Give each its own duration and buffer so the calendar reflects how you really work.
Calendar sync
Seamless sync with Google, Outlook and iCloud keeps availability accurate in both directions and keeps your pipeline up to date as bookings land.
Time-zone intelligence
No more “what time is that for you?”. Clients see slots in their own time zone, which matters as soon as you work with anyone outside your city.
Deposits at booking
Integrated payment processing lets a client choose a time and pay a deposit in the same step, so the slot is committed rather than pencilled in.
Instant confirmation
The client receives confirmation immediately, and your calendar and sales pipeline both update without anyone doing it by hand.
Buffers that protect the day
Per-service buffers stop appointments stacking back to back, so travel and write-up time is respected automatically.

Benefits
What changes day to day
The practical difference once this is running.
-
Fewer emails per booking
One link replaces the thread of proposed and re-proposed times.
-
No double bookings
Two-way sync means the availability you publish is the availability you have.
-
Firmer commitments
A paid deposit turns a tentative slot into a confirmed one.
-
Works across time zones
Remote and cross-border clients see times that need no conversion.
Use cases
Where it earns its keep
Three situations teams tell us about most often.
On-site survey slots
Publish survey windows with travel buffers built in, so a booked day is actually achievable.
Discovery calls
Share one link that shows genuine availability and collects a deposit for paid sessions.
High-volume scheduling
Different services with different durations run off the same calendar without colliding.
FAQ
Booking questions
What teams ask before switching this on.
Which calendars does booking sync with?
Google, Outlook and iCloud. Sync runs in both directions, so external commitments block your published availability and new bookings appear in your normal calendar.
Can different services have different lengths?
Yes. Custom appointment types let you set a separate duration and buffer for every service or meeting type.
Can I take payment when someone books?
Yes. Integrated payment processing collects a deposit as part of the booking step, and the client receives instant confirmation.
What happens to the deal in my pipeline when a booking is made?
It updates automatically. The calendar and the sales pipeline move together so you are not recording the same outcome twice.
