Connecting is two decisions and about a minute: sign in to Intuit, then say which of your QuickBooks companies this property belongs to. Prostay never asks for a QuickBooks password, and the connection is per property, so a group with four hotels connects four times.

What you need first

  • A QuickBooks Online subscription, and an Intuit sign-in that can authorise apps for it.
  • To know which QuickBooks company this property's takings belong in. If your accountant keeps one company per hotel, this matters and it is not easy to undo.
  • The Connect / authorize QuickBooks permission on your role.

Connecting

  1. Open Integrations and press Connect on the QuickBooks Online card.
  2. Press Sign in with Intuit.
  3. Sign in and approve the connection on Intuit's site. That page is Intuit's, not Prostay's, and what it asks for is between you and them.
  4. You come back to Prostay, at the company picker below.

Prostay never asks for your QuickBooks password. Intuit does, on its own site.

While it waits, the screen says Connecting to QuickBooks... If you close the tab at that point, nothing has been connected and you can start again from the card.

Choosing the QuickBooks company

If your Intuit sign-in reaches more than one QuickBooks company, you are asked which one this property posts to. Everything this property ever sends goes into the company you pick here.

A screen headed Select QuickBooks Company listing two rows, Marlowe Hospitality LLC and Marlowe Hospitality Holdings LLC, both in Portland OR, each with a chevron on the right.

Picking a company takes you straight into the mapping wizard, because a connection with no mapping cannot post anything. Map your QuickBooks accounts covers the three steps.

What you get once it is connected

The connected QuickBooks screen headed Marlowe Hospitality LLC with a green Connected badge, buttons for Configure, Disconnect and Sync Now, and three cards reading Last Sync 8/14/2026 2:15:00 AM, Sync Mode Daily Journal, and Pending Items 9.
What connecting produces. Pending Items counts the lines waiting in the next journal, not the days you are behind.

  2. Configure reopens the mapping wizard at step one. Nothing is lost by looking.
  3. Sync Now builds the next journal entry and shows it to you before anything is sent.

Three things on this screen are held separately by permission. If the QuickBooks Online card is not on your Integrations page at all, if Sign in with Intuit is greyed out, or if Sync Now is greyed out, your role does not include the permission for that part. An administrator can add them from Users in System Settings, under IntegrationsQuickBooks connection, where seeing the connection, connecting it and running a sync are three separate rights. It is normal for a bookkeeper to hold the sync and not the connection.

The three cards under the header are the state of the connection:

CardWhat it means
Last Sync When a sync last ran, successful or not. A run that failed still moves this, so read it with the activity log rather than on its own.
Sync Mode Daily Journal or Per Invoice, whichever you chose in step three of the wizard.
Pending Items How many lines are waiting in the next entry. It counts lines, not days, so nine here is one night with nine lines in it.

Disconnecting, and what it leaves

Disconnect asks you to confirm, then drops the connection and returns the screen to Sign in with Intuit. Syncing stops immediately.

What it does not do is reach into QuickBooks. Journal entries already posted are documents in your QuickBooks company and stay exactly where they are. Nothing in Prostay changes either: no folio, rate or reservation is touched by connecting or disconnecting.

Common questions

  • Can one QuickBooks company serve two properties?

    Nothing stops you choosing the same company on two properties, and both will post into it. Their entries will sit side by side with nothing in the entry itself naming the hotel, so most groups that try this end up separating them again. Decide it with whoever reads the books.

  • I picked the wrong company. How do I change it?

    Disconnect, then connect again and choose the other company. That changes where future entries go. Entries already posted into the wrong company have to be dealt with in QuickBooks, because nothing in Prostay can withdraw them.

  • Does Prostay store my QuickBooks password?

    It never sees it. You sign in on Intuit’s own site and Intuit tells Prostay that you approved the connection. There is no password field anywhere in this module, and nothing to rotate here if you change your QuickBooks password.

  • The screen has been saying Connecting to QuickBooks for a while.

    Nothing has been connected while that message is on screen. Reload the page and start again from the card. If it happens twice, the authorisation is not getting back from Intuit and that is worth reporting rather than retrying.
