This video shows how to change a reservation’s dates in Roomdoo. Below you’ll find the step-by-step details.

​
Before changing the dates

Before modifying a reservation, check two things:
1

There's real availability in the planning for the new dates

If there’s no free room of the matching type for the new dates, the system won’t allow the change. You can see this directly in the PMS planning.
2

The reservation isn't from an OTA

The dates of reservations from external channels (Booking.com, Expedia, Hotelbeds, etc.) can’t be changed in Roomdoo. The change is made in the OTA itself and then syncs automatically into Roomdoo. More on this below in Locked reservations.

​
How to change the dates

1

Open the reservation

Click the reservation in the planning. You can also use the search bar in the top-right corner and find it by booking reference or guest name, or open it from the Reservations list with View in planning.
2

Reservation tab → Details

Inside the folio, go to the Reservation tab and, within it, to Details.
3

Change dates button

In the Reservation dates section, on the right, you’ll find Change dates. If there’s a padlock icon next to it, the reservation is locked (see below).

4

Pick the new dates

A pop-up opens with two calendars: the new check-in on the left and the new check-out on the right.

5

Review the price

Nights the reservation already had keep their price. New nights take the rate’s price while Set price according to assigned rate is on. If you turn it off, you can set a Fixed price per night (with a % Discount) or, turning that option off too, the price of each new night. At the bottom you’ll see the Before the change / After the change summary.
6

Save

Click Save and the reservation is updated. The planning refreshes automatically.

​
Keeping the original price

If the guest wants to keep the price they had, turn off Set price according to assigned rate and give the new nights the same nightly price the reservation had, with Fixed price per night or night by night.

​
Early departure: release nights without shortening the reservation

If the guest leaves early, you’d normally shorten the reservation with Change dates. Sometimes you can’t, or it isn’t the best option:
  • The reservation comes from an OTA and its dates are locked.
  • The reservation already has a validated invoice that includes those nights.
  • The guest will pay for the nights anyway (for example, on a non-refundable rate) and you only want to sell the room again.
In those cases, mark the remaining nights as Reselling: the room becomes available again on those nights, OTAs included, and the reservation keeps its dates, amount and invoice.
1

Open Manage room

In the reservation, go to the Room tab and click Manage room.
2

Turn on Mark reservation as Reselling

The reservation calendar appears, with a Reselling checkbox on each night.
3

Tick the nights you want to release

Tick only the nights the guest won’t stay. Roomdoo warns you: “If you mark the reservation as Reselling, availability will be released automatically and you may run out of space at the property.”

4

Save

Click Save. The reservation now shows the Reselling status and those nights are free to be sold.The reservation’s departure date doesn’t change, so the check-out is only available from that date.
Reselling doesn’t change the price: the ticked nights stay in the reservation with their amount. If the guest also shouldn’t pay for them and you can’t shorten the reservation, contact support, as a corrective invoice may be needed.

​
When the reservation is locked

If after clicking Change dates you see a message saying “Reservation blocked — It is not possible to modify the dates of this reservation”, it almost always means the reservation came from an OTA. Roomdoo locks modifications on these reservations automatically, so the change in the PMS and the change in the OTA don’t get out of sync.

​
How to know which channel the reservation came from

Inside the reservation, in the Reservation → Details tab, there’s a field called Sales channel (and, if the reservation came through an agency or OTA, another one called Agency) that shows where it came from (Booking.com, Expedia, direct website, etc.).

​
What to do

1

Identify the OTA

Look at the sales channel in the reservation file.
2

Make the change from the OTA

Go into the corresponding OTA panel and change the dates there.
3

Wait for it to sync back to Roomdoo

As soon as the OTA confirms the change, it syncs to Roomdoo automatically. It usually takes seconds to a few minutes.
If the change can’t be made in the OTA and it’s urgent, contact support. Keep in mind that a date change made in Roomdoo isn’t sent to the OTA: the reservation stops being in sync with it and, if the OTA later sends a modification, it will put its own dates back.
The system message doesn’t explain why it’s blocked. If the user sees this, it’s most likely an OTA reservation — check the sales channel to confirm and guide them to the right channel.

​
Common cases

Possible causes:
  • The room type isn’t the same. You’re looking at free rooms of a different type than the one in the reservation. Availability is checked by room type, not globally.
  • Free rooms have a restriction applied (minimum stay, sales stop, channel restriction). A room can be physically free but not on sale for that specific date.
If it’s none of these, contact support.
If the reservation didn’t come from an OTA but is still locked, there’s probably a special flag applied (for example, a reservation created via an external integration that left the lock on).In that case, contact support with the booking reference — we’ll review it.
It appears when Roomdoo rejects the change at the final step (on save), not when it blocks the modification from the start. First a Something went wrong window shows the reason, then a second one with a generic message: the first message is the one that tells you the cause. The usual causes are:
  • The reservation already has an issued invoice and the change would affect billing
  • A conflict with another reservation that landed in the new dates right before you saved
  • A temporary database connection issue
Try again. If it persists, contact support with the booking reference.
If searching by booking reference or guest name doesn’t return the reservation, first check that your filters are correct (no date filters in the way, on the right property).If it still doesn’t show up, it could be:
  • The reservation is cancelled and your filters hide them by default
  • You’re searching by an internal channel manager code: search by the OTA booking reference, the folio number or the guest name instead
  • The reservation hasn’t arrived from the OTA yet (wait a few minutes and search again)
After checking the above, if it still doesn’t appear, contact support.

​
When to contact support

Contact support when:
  • The folio’s Invoice tab shows an invoice number with a series already issued (not the text “to invoice”)
  • The reservation is from an OTA and the change can’t be made in the OTA
  • The reservation can’t be found and you’ve checked the usual filters
  • “Reservation blocked” appears on a reservation that didn’t come from an OTA
  • After several attempts, the generic “Something went wrong” keeps appearing
Don’t try to “duplicate” the reservation or create a new one with the dates you wanted as a workaround. If there’s an issued invoice or complex services in play, doing so leaves accounting fragments that won’t reconcile. Better to ask support to modify the original one safely.
