Take in-person card payments

Pair a SumUp Solo card reader with LemonBooking to take in-person card payments. Find the invoice, press “Take payment”, the reader activates and asks for the card. The result comes straight back: payment saved, receipt generated, invoice marked paid.

It works for invoices, memberships, tickets, classes and one-off payments — and refunds run back through the same reader too.

  • 1.29% per transaction for LemonBooking customers
  • 10% off Solo readers through our SumUp partnership
  • Payments flow into your accounting software

Save on heating bills

Connect one or more Google Nest thermostats to control them with your LemonBooking calendar data. The heating comes up before a hirer arrives and drops back down once they've gone, without anyone remembering to do it.

You create two targets per thermostat — say 18°C in use and 10°C idle — then set rules that decide when each applies. Rules can key off day of the week, time of day, time before or after a booking, booking category, facility, location, or even a particular customer.

Save time on key management

Key management eats volunteer time: meeting a hirer to hand over a key, chasing it afterwards, cutting a replacement when it's lost. Fit a Nuki smart lock and LemonBooking issues a PIN instead — for a customer, or for one booking only.

Because the codes come from the calendar, they stop working when the booking ends. And because every entry is logged, you always know who was in the building and when.

Speed up event check-ins

Every ticket LemonBooking sells carries a QR code. Staff and volunteers can scan it with a phone, or with a handheld QR code reader plugged into a laptop on the door — which is faster once a queue builds up, and easier to hand to someone who has never used the system.

Any USB QR code reader that emulates a keyboard will work, but we recommend the Eyoyo Handheld USB 2D Barcode Scanner, about £30 on Amazon UK. Plug it in and you're ready to go. No software needed.

If your venue already runs a different heating or access system, you don't have to replace it. Sync your bookings to Google Calendar for software that reads calendars, or pull locations, facilities, opening hours, customers, bookings and time slots straight from the LemonBooking API.
