Connect your diary to Square
Below you can find a list of information on how to connect ResDiary to your Square POS account:
We do have a guide that explains this process thoroughly.
Only your ResDiary admin user with admin access to the Square account can connect the two systems.
You can connect more than one location, but note that revoking or disconnecting the integration in one location will remove access for all locations under the same Square merchant. If you manage multiple venues, plan carefully or contact our support team before disconnecting.
By connecting to Square you’re granting ResDiary secure access to:
Send bookings to Square with guest details.
Read check, payment, and table updates from Square.
Manage your connected locations.
📌 Note: This doesn’t give us access to your bank or financial reports, only to the data needed for syncing bookings and payments.
Map your venue
This sections highlights tips to ensure you diary information is synced correctly:
📌 Note: If your table names don’t match on Square, bookings won’t appear on the right tables in Square.
Match your booking buffer time
This feature automatically links Square checks to ResDiary bookings when you open a check directly in Square, instead of seating the booking in ResDiary first.
When you have a booking on a specific table and open a check in Square on that same table, the system automatically matches them together, even if the customer arrives early or late.
For example, if you have a booking for 7:00 pm, on table 12 on ResDiary, instead of seating it in ResDiary, you open a check directly in Square on that same table 12.
With the five minute buffer, if you open the Square check on table 12 anytime between 6:55 and 7:05 it will automatically match to your ResDiary booking.
📌 Note: If you prefer to seat bookings in ResDiary first, you can do so at any time. This buffer only applies when you open checks directly in Square.
