The erphome reservation page is a handful of tools that together make you independent of Booking.com and Airbnb. Here is each of the main ones on its own, with specifics, setup steps and answers to the usual questions.
Automatic calendar sync with Booking.com and Airbnb over iCal. Occupied dates block everywhere, and double bookings stop happening.
Take booking payments into your own account through Przelewy24 or PayU. The booking confirms itself automatically once the money arrives, with no commission.
Generate a one-off payment link (BLIK, transfer, card) for a booking or a deposit and send it to the guest by email or text.
Put an apartment booking form on your own site with one line of code. The widget shows availability, and the booking finishes with you.
A full overview of everything is on the home page, and step by step in the help centre.
