Questions, answered.
What is HoldKit?
HoldKit is modular booking software. It gives your business an online calendar and reservation system where customers choose what they want, pick an available date or time, fill out any forms you require, and complete their booking. You can subscribe to the full platform or only the modules you need.
Can I buy only one module?
Yes. Individual modules are $9.99/month each. You can add or remove modules as your needs change.
Do I need the full platform?
No. Many businesses start with a single module — for example, just Calendar Booking. The Full Kit is there when you want everything working together.
Does HoldKit support payments?
Yes. With the Payments & Deposits module you can collect full payment, a partial deposit, or no payment at booking time, and track balances until they're settled.
Can HoldKit be used for rentals?
Yes. HoldKit supports date-range rentals with availability tracking, quantity limits, deposits, and pickup or delivery details — for anything from party equipment to tools, gear, and vehicles.
Can I use HoldKit for appointments?
Yes. The Calendar Booking module handles time-slot appointments with configurable durations, buffers, lead times, and working hours.
Can I reserve products or inventory?
Yes. The Inventory Reservations module tracks how many units of each product or item you have, so customers can only reserve what's actually available for their date.
Can customers book online?
Yes. Every HoldKit plan includes an online booking page. Customers browse availability, make their selection, and book from any device — desktop, tablet, or phone.
Can I customize booking forms?
Yes. The Custom Booking Forms module lets you add your own fields — text, choices, checkboxes, addresses, and acknowledgements — so every booking arrives with the information you need.
Is HoldKit only for event businesses?
No. HoldKit works for appointments, rentals, equipment, venues, classes, services, product reservations, and events. It's a general-purpose booking platform — you model your workflow, not the other way around.
